Unreal engine 5 Create ship game with destroyer navy ship with artilleries as enemy

1. 00 Promo: In this course, we learn everything about creating ship that can go through ocean or sea. So first, we create a ocean, and after that, we import some files for our ship. And with that files, we create our ship, and we add some pontoon to it so it will float on ocean. After that, we will use physics force to go forward, go backward, go left, go right. And with all of these, we have animation for its blade. So when we go forward, the blade will rotate and when we go backward, the blade will rotate backwards, right? Next, or ship has a gun, so we can use it to shoot at our enemy. With our gun, we limit it so it won't be able to shoot at our ship. And we have a Zoom capability as well, because our ship can shoot far away. Next, we add some UI like cross hair and health board to it. Next, we need some enemy. So for enemy, we will use a artillery for our beach. So whenever our ship go in front of these artilleries, they will shoot at our ship. And whenever they shoot at our ship, it will have some physics impulse added to our ship, and it can move our ship. Our anti ship gun has lots of visual effects and sounds. So for example, whenever it shoot the barrel will go forward and backward. At the end, we create a ship destruction, as well. So if our health reach zero, or ship will be destroyed. After that, whenever we shoot at our enemy or enemy will be destroyed. So let's learn how we can do that. Without any further ado, let's begin. 2. 01 Create project and make it ready for Ship: For creating a ship game, we need to create a project. And for this project, I'm using ARIO Engine 5.5 0.3. And my recommendation is to use this version that I'm using because in each new version of ARIO engine, they are changing the names. So if you are a beginner and you want to do exactly as I'm doing, just stick with the version that I'm using. So I did open up ARIEL Engine 5.5 0.3, go to Games in here and create a blank project. In here, we needed to be in blueprint. We don't need the starter content, and I want to name this ship. Right? And you can choose where do you want to put your project by clicking in here and put it in whatever folder that you want. After that, you can say head create. No or project is open. At description of this video, there is a zip file that is called ship dot Zep. Download it. Put it on your desktop. You can just click on it to open it, and there is a folder inside it that you can just drag and drop it and put it on your desktop, so it will be extracted. No, we need to import it in ARIEL Engine. For doing that, go to Content drawer, click on the content folder, right click on it, and click on Showing exxplorer and it will open up the content folder of our project in Windows Explorer. And the only thing that we need to do we need to just drag and draw up this ship folder inside this content folder. Don't put it anywhere else. Don't rename anything. Just do as I'm doing, right? Just with that, if you go to ARIEL Engine, you can see the ship folder is in here, but if you double click on it, there is nothing there. The reason is we need to restart our engine, so all of those assets will reappear. But before doing that, I want to change some settings. So for example, go to Edit, go to Editor preferences, and in here, search for open and change the asset editor open location from default to main window. So whenever you open something, it will be open up up here. You can just close this next thing that you want to do. We want to save this level, so head control is on your keyboard and save it wherever you want. You can name your level, whatever you want, as well. But I want to just name it new map, head save, and it will be saved. Now, if you go to Content drawer, click on the content folder, you can see the level is saved in here. Now, next thing that we want to do, we want to go to Edit project setting, and in here, go to maps and modes and change the editorial starter map and game default map from open Word to new map that we create. First time that we are doing it, it will change it to none, but again, click on it and change it to New Map. Do it for both of them like this, go to set the new map there. So whenever we open Arial engine, it will open up over level for us. Now, you can just close that. That's next thing that you want to do. We want to go to edit, go to plug in, and in here, search for water because you want to have a ship. We need some, for example, ocean, right? So we need to enable this water login, enable it, and in here, head yes, and it will tell you you need to restart REL engine. So click in here to restart RILEngine. So all the assets and necessary plugin will be there when it is open, right? Now when the project is open for the first time, there is a error in here. It says collision profile setting, do not include an entry. For fixing that, you can go at the end in here and click on this ad entry to default engine INI. Just click in there. It will add it there automatically. You don't need to worry about it. You can just close it. Now, if you go to content drawer, you can see if you go to ship, you can see the assets folder there. We have lots of things. For example, if you go to SM, you can see a static mesh in here. If you go to Vigilante content, go to vehicle, go to West Ship, you can see a ship in here as well. First thing that I want to do inside this level, what I want to do, I want to add ocean, right? Right now, there is no water at all, right? So for doing that, we need to go on here, click in here and search for ocean, right? And drag and drop this ocean wherever you want, inside or level, right? And now you can see, because we put that there, there is a ocean with a small island, and we can't see or open word. How we can fix that we should click on Water body ocean, go to DtilPanel, go down in here until you reach the train, expand water, height map setting, and change the blemo from Alpha blend to max. No, if you go close, you can see we can't see any water. But if you bring this up a little bit, you can see the water will fill up a level. Now, you can see we have a island at the middle. We can just click on it and make it a smaller like this. Just click on it and make it a smaller. We don't need it that much. Again, click on this point, make this a smaller. If you want to have island, you can do that. But I want ship to lots of room to work with, right? No, with that, you can see it small, and we can make it smaller, as well. Sometimes our real engine crash, so make sure you save a lot. You can see. I'm making this as small as possible. If you don't want this hole to be in here, you can go to selection mode, go to landscape. Make sure you save everything because real engine crash a lot, saving it, right? And no, in here, we can go to scalp, to a scalp and change the tools sernth to one, so it will happen. And next, I want to change the brush size a little bit. You can see it. No it's good. And we can bring these parts up like this, right? That looks good, right? We have a small mountain at the middle of our island in here, and we can put some sp inside this ocean. So next thing, let's just go back to selection mode and we have our ocean. No, there is a warning in here that you can just click in here. It's some water body or not up to date. You can just click on Mark dirty to get rid of that warning if you have that warning. No, we are ready to create a ship blueprint. So make sure you save everything, and you can just close this plug in folder. Now, we are ready. Let's begin. 3. 02 Ship blueprint: Now that we have a ocean, we need to create a ship. Let's see how we can do that. For doing that, I want to go to Content drawer, go to Ship folder in here, right click, create a new folder and I want to call it Blueprints. So all of our blueprints will be here. Right click in here, create a blueprint class. This time, I want to create a type of pawn, so we can be possessed and receive input from a controller, right? So click on Pawn and I want to call it BP Shep, right? I'll click on it to open it. Now in here, what we want to do first, we want to add or ship. But if you go to assets, you can see, we have a skeletal mesh, right? But right now, the ocean and buoyancy of argo engine doesn't work with a skeletal mesh. That's why we have a static mesh of the exact so if you want to have another ship, you need the aesthetic mesh of it as well, exactly at the same size. You can use one of its LODs. If you have a three D artist designer or UNO blender or three D Max or Maya, you can do it yourself. Just one of the low poly LOD of it, create a estatic mesh of it, and imported in AL engine. That's what you want to do. So first thing first, inside this BP ship, what you want to do we want to click on AD and add a estaticms because we know that ARL engine buoyancy and ocean will work with estatic mesh correctly. So add estatic mesh. And because we select the estatic machine here and we did create it over here, that's why it did put it there. You can see this is our ship, right? And it's called untitled. Let's just change that to ship for estatic mesh and drag and drop it and put it as default sin root. Next, with that, what I want to do I want to add a skeletal mesh now as a child of it, right? I want to call it ship. Right? And for the skeletal mesh of it, I want to choose SK west ship, right? Just put it there. Now, you can see both of them in in here, but we want to click on our ShipSM and change the visibility of it. So let's just go down until we see the visibility. We don't want it to make it visible, right? That's it. Now, we have a ship that we can use. With that done, we need to add a spring arm. So with it, we have a camera as well, and click on the spring arm after that and add a camera. Add the camera in here as child or spring arm. Now, with or spring arm, I want to change the length of it to 15,000, right? So it is way back. You can see it. The camera is way back in here. So that's good. If you want to change the target arm length to something bigger or smaller, you can do that. Next, let's just add some offset to the Z. So we bring it up a little bit. Example, 180, and next thing that we want to do, we want to enable use pawn control rotation. So the rotation or spring arm change with the rotation of our controller. No, next thing that I want to do. I want to click on or ship aSM and add the arrow there as well. With this arrow, I want to check the forward vector. So click on it. And because you can see it is too small over here, we can't see it good. So I need to make it bigger. Change the arrow size to something big, 130. No, you can see the forward vector or what is the direction in forward, right? Forward ctor. Now with that now, let's just he compile save. I want to go to Content drawer and I want to go to Ship folder. After that, in Blueprint folder, I want to right click, create a new Blueprint class. This time, I want to create it from game mode base. I want to call it GM BP for game mode blueprint. And we want to call it ship. That's it, don't click on it to open it. And in here, the only thing that you want to change is default punk class. So click in here and change it to BP sheep. That's all we need to do inside this blueprint. You can just close it. Now, we can go to our level and go to Wordsetting. If you don't have this word setting, you can go to Window and open up the word setting. In here, we want to change the game mode overt from non to GMBP Shep. That's it. No, I here, we have player start? Let's just find it and put it on water. Right now, it is not on water. Let's just at F to see where it is. You can see it. It is over here. Now with that done, if you run over game, you can see, we have the ship, we can't move. I won't fall down at all. Let's see how we can fix that. For fixing that, we need to go to BP Ship, click on ShipsM in here, we want to enable simulate physics. We want to change the mass to 100, for example, so it will be easier to manage it, right? So we don't need to put a lot of force to it, so it will move. So with 100, it will be easier. Next, let's just go down and in here, the collision presets, we want it to be physics actor. If it's not physics actor, just click in here and change it to physics actor. And that's it, Let's just had compile, save, and go to our level and run. No, you can see it will fall off into the water, and you can see it's not floating at all. This is a problem. Now, with that, you can see the depth of our ocean is not too much in here. Let's just put it over here and no, let's just run. You can see it is going inside the water and it's hitting the ground beneath the water, right? We don't want that to happen, so we need to make it float. How we can do that, there is a tools in our engine that c buoyancy, and we want to use that next 4. 03 Ship pontoons: No, we have a ship, but it is sinking. How we can make it float. Let's see. For making it float, there is a tools in Area engine that is called buoyancy. So click on ad and search for buoyancy, right? This is the one. Click on it too, add it there, and know with that, you can see there is a buoyancy option. So we need to set up buoyancy data. If you expand this, you can see we have lots of things to set over here and make it customized, right? So first thing first in here, we should add some pontoons. With these pontoons, we can make a boat float to make our ship float. And how we can do that, if we open up the estatic mesh, you can see inside this estatic mesh, I did create some sockets, and you can see the first socket that I create is at the middle at bottom of our ship. There are other sockets as well at front, two at front, atside of our sheep, and there is two at back aside of or ship as well. If you want to add more, you can do it. For example. Let me create the sixth one. If you click in here, it will add another one, and I can position it. For example, I want one of them to be here, right? At back of over a static mesh, and we can add more at front as well. For example, add one in here. So click on at and add it at front, right, like this. And we can name it. For example, this one, head F two, so you can rename it. Put six there, and this one, I can put seven there, right? So no these sockets positions we can use pontoons, right? So for example, the socket number one, the position, the relative location of it is 00 -500. The socket number two is this relative location. The number three has this relative location, and we want to use this sockets position to place our pontoons. So no, for creating pontoons. Let's just go to BP ship, and in here, click on buoyancy and add some pontoon. I need just five of them, but if you want to add more, you can do it. So click in here to add five no, for the first one, you can see, we can put a socket there, but for some reason, it doesn't work. It has a box. So I won't use socket, but I will use relative location. So, for example, the socket number one has the relative location of zero, zero -500. So let's just put it there. 00 -500, right? No, the radius you can change it, how much you want it to be big, but 100 is more than enough. Let's just go to the next one. Index one. Again, I don't want to use socket. I want to just use the socket location. So let's just go here. The socket number two. I can right click in here, copy the values over here, and go here and right click in here and paste it over here. You can see, no, I did put it there. I don't need to change anything. No, I can go to index two. For Index two, I want to go to socket three, right click in here, copy the positions, and let's just paste it over here. Right click paste, and it will put the values there. No, we need two more in here for socket number four. I want to right click copy the position and paste it for this one, right? Right, click Paste. That's it. No, there is just one more Well, just click in here on number five, right click Copy and go to BP ship and in here, paste it for relative location, right? No, you know that we have six and seven in here, but I don't want to use them, so I can just delete them. We don't need it. If you want to add them, you can add them. You can add more pontoons in here and add their position as well. But these five is more than enough because if you have more pontoons, it will be harder for PC and CPU to process all of this, and we will have drop in frame rate. So no, let's just he compile, save go to Olevel run over game. No, you can see it is floating. If I hit F eight and go into the water, you can see it is floating. But you can see this is hitting the ground. But as you can see, it is floating. For you to see it better, what I want to do, I want to stop this and click on water body ocean and bring it up a little bit like this and know that if you run over game, if I eject and go beneath the ship, you can see, it's it's floating. It's not hitting the ground. So over ship is floating and everything looks good, everything awesome. Now, let's say you want the back of over ship to be a little bit down how we can do that. For doing that, we can go to our BP ship, click on buoyancy and change the Z value of the ones to -20, for example, for both of these, -20, and we can decrease this more to -20. It's just for this. Let's just head compile and run, no. Can see. No, it is completely into the water and down. You can see. That looks really awesome. If you want to just leave it with these values, you can do it. But if you want to change the position of these pontoons, you can do it. You can bring the pontoons up. So this sp goes down into the water more. You can play with these values until you reach the result that you want. But right now, you can see it is into the water, and I think it looks awesome and it is floating. No, it's time to be able to look at overshp with the inputs with the most. Let's see how we can do that in next 5. 04 Input mapping: No first thing that we want to do we want to be able to look around with our mouse. For doing that, we need input mapping context and some input action. So let's just go to ship folder. I want to right click in here, create a new folder, and I want to call it inputs, right? Do click on it to open it, right click in here, go to input and create a input mapping context. I want to call it IMC ship. Dog click on it to open it. After that, I want to create input action. So right click in here again, go to input and create input action, and I want to call it IA L around A for input action, right? No, don't click on this input action. I want to change the value type from digital Bollan to access to D. So what you want to do with the X and Y of mouse we want to be able to look around. So let's just save this. We can just close it. Go to IMC ship input mapping Context Shep, click a Mapping to map or input action. Click in choose I look around and in here, how we want to look around, we can just click in here, go to moose and put Msx Y to the axis, right? It will give us X and Y of our mouse. Now, with that done, we need to implement our IMC ship inside or BPsp. So go to event graph in here at the begin play. I want to get the player controller in here, and with that, I want to get the enhance input local player subsystem and add over mapping context to it. Add mapping context, right? We want it to happen just once. It is more than enough. The mapping context that you want to implement is called IMC ship. Now with that done. If you go down in here, find some space, right click Search for IA, L around. There is two of them. One is action value and one is action event. We need the action event. So click in here to it there, right? No, the action value, if we drag and drop and break it, break the vector two D, it will give us X and Y of our moss, right? And with it, we can change the rotation of our controller. And because on this spring arm, we did tell it to use paw control rotation, it will use the rotation of our controller. So in here, the only thing that we need to do is changing the control rotation, for example, with X, we want to change the control a rotation. So we look left and right. Rotation around the Z axis, it is called Ya. So we say add controller. Your input with what value with the X, right? Just with that, if you head compile and run, you can see, with the mouse, I can look left and right, and that does look good, right? Now, the next thing that we want to do, we want to change the control, pitch rotation or rotation around the Y axis, so we can look up and down. And for doing that, again, we can say art controller, pitch input with the Y value of over most. Now with that one, if you head compile save and Runo game, you can see I can look up and down, but it is inverted. So for making it invert again, so it will be easier to work with, we can go to IMC ship. In here, we can add a modifier to over input action. So add the modifier in here of type of negate. And the only thing that you want to negate is just the Y. So unselect the X and Z and just leave the Y there. Just with that, if you had safe and run over game, no, you can see we can look up and down easy. We are looking around over ship. Now, it's time to move over ship, move it forward and backward. Let's see how we can do that next 6. 05 Moving forward and backward: Now let's see how we can actually move over ship. How we want to do it because it is a physics body, we can apply some force to it. Let's see how we can do that. For doing that, first of all, we need input action. So right click in here, go to input and create input action. I want to call it I move forward, backward, right? I'll click on it to open it. The value type, I want it to be axis one D, a float. That's more than enough. No, we want to map it. So go to IMC ship create a new mapping. We want to do it for move forward and backward. And in here, we want it to happen with W with W, we go forward and add another input this time, click in here, head S on your Tboard, put the S there. Whenever we had S, we want to go backward and we want to have a minus value. A negative value. So that's why I want to add a modifier of type of negate like this to pass minus one whenever we hit S on our keyboard. Now with that done, let's just go to our BP Ship, find someplace, for example, in here, search for A, move forward and backward. And in here, let me bring this down over here. First thing that you want to check, we want to check our buoyancy and check if it is in a water body. So if it is in water, we can move it forward and backward. So we will check this with the branch to connect the execution pin to it, right? If we are in the water, this true will happen, and with that, we want to get our ship SM and add force to it. So search for add force. That's it and connect the true to it, right? No, it needs a force. How we can calculate this force. We want to add this force in forward direction of our ship. And you remember we add this arrow in our ship, so we get the forward vector of overship with this arrow. So we can get this arrow get the forward vector of it, search for Get forward vector. Next, because this forward vector is a length of one. I won't move or ship, so that's why we need to multiply it by some big value. So right clicking here, change it to float. So we multiply or vector by a big float value like 320000, for example, we need to test this until we reach the result that we want. For no, just leave it as this value, right? A really big value. Now with that done, we need to be able to go forward and backward, and for doing that, we can use this action value. If we W, it should go forward, and it is giving us one. And if we S on or keyword, this action value will be minus one. So we can multiply, multiply this by the action value that whenever we S, it will give us. Minus one and whenever we hit W d one, and this is our force. We can just put it there. Now if you had compile save go to our level and run over game. Now, if I hit W, you can see it is going forward. And if I it Son or keyboard, you can see it is going backward. That's good. You can see the force is too much, so we need to decrease it. Of course, again, you should play with these values a lot. For example, I want to divide this value by two. Now, if you go to our level and run over game, you can see it is going forward and we can go backward and it does look good. So no next thing that we want to do. Whenever we are going forward, we want to rotate these blades that we have at the back of our ship. So our ship looks much better. Right now, if you go backward or forward, you can see the blades are not moving. Let's see how we can do that. Next. 7. 06 Rotate blades: Know that where ship is moving, we need to rotate the blade so it looks much better, right? So for doing that, we need animation blueprint. So let's just go to content drawer, go to Ship folder, go to Blueprint and in here, right click, go to animation and create animation blueprint. I want to create it for a scale West ship head create and I want to call it ABP ship, right? And don't forget to put this animation blueprint for ship a skeletal anim class. So click in here and it will put it there because we select it over here, right? Or you can just click in here and choose the ABP ship. That's it. No, these two is connected. Let's just see what we can do with that. Double click on the animation blueprint to open it. And in here, first thing that you want to do, let me make this a smaller in here. I want to search for mesh mesh space RFO, so it will give us all the information about the bones inside our skeletal mesh, right? Now, we can do whatever we want with the bones that our sp has. Let's see what bone we want to rotate. For doing that, I want to go to a skeleton by just clicking in here. With that, it will open up the skeleton on our sp. The bones that we want to rotate is these blades in here. Let's just see which one is it. Click on screw joint. You can see, this is the first one that you want to rotate like this and we have left screoint LF screw joint. Again, we want to rotate this as well as you can see. These are the ones that you want to rotate. RT joint. And L F screw joint. This LF means left. This RT means right. Now, how we can do that. For doing that, we have a node that is called modify bone or transform bone. And in here, the bone that we want to rotate, you know that it is we the screw joint and left the screw joint. So choose one of them. We will copy and paste that for the other one as well. What we want to do we don't want to change the translation or a scale. We want to just change the rotation. So in here in detail panel, we can tell it to not expose the translation as pin. You can see it is much cleaner. And for the scale, again, click in here and tell it not to expose as pin. Now, right click on this rotation, split a stroke pin, so we can just change one of these rotations. But for no, which one do we want to rotate? If we go back to our skeletal mesh and he told you, you can see the rotation around the X axis, we want to change, right? The rotation around the X axis, this red one is called role. So that's why we need to change just the role. By default, it will ignore the rotation mode, so we need to click in here and change it to add to existence, and that's it. Now, if we change the role, zoom in here a little bit. We are doing it for the left one. So if you change the row to, for example, 20 and head compile, you can see it is rotating. But I don't want to do it like this. I want to right click on this one, promoted to variable, and I want to call it blade rotation, right? Blade rotation. Know with that done, we can test it in an in preview editor. If you don't have this, you can go to Window and open up an in preview editor. By default, it should be there. Now with that done, if you change the value for blade rotation, you can see the blades are rotating. That's cool. Now, we can copy and paste this node with Control C, Control V to paste it over here and connect it like this, right to here and here. In this one, we want to change the right blade or right screw joint, change it to that and we can use the same variable for the role of this one as well, head compiler, save, and know if we go to preview editor, you can see we are rotating both of them with changing this value, right? But how we can change this value. We want to do it based on the action value, based on the inputs that we have. So let's see how we can do that next video. 8. 07 Force Factor: No, based on the inputs for going forward and backward, we need to rotate the blade, but how we can do it. Let's find out. For doing that, I want to go to BP ship, and in here, on each frame, I want to check if there is any input, right? So in the eventi, we want to check that. So every frame, we are checking that, right? But I don't want to mess this event tick up. What I want to do, I want to create a custom event in here. Search for custom event. I want to call it engine. Manager, right? So, based on the engine, the force that we have, the movement that we have, the input that we have, we want to rotate the blade, right, and we want to connect this custom event to the eventi. So in here, just put the engine manager in here. It's like, whatever we connect to this custom event in here, engine manager, it's like connecting it to the eventi. Now in here what we need to check is to check I move forward and backward action value this time, action value. We want to check. If this action value was bigger than zero, it means we are going forward, and we want to check that with a branch like this, right, connected like this and know if we are going forward, this I move forward backward will give a value bigger than zero, one, at most cases, right? This true will happen, and with it, we want to smoothly rotate the blade, right? So how we can make it this move, we can do it with a variable. So let's just create a variable of type of float and I want to call this one force factor, force factor, right? Just call it force factor. And by default, this force factor will be zero, and we want to smoothly change it to one. And how we can do that, we can do it with F interp two, right? The thing that you want to change is our force factor. So connected to the current, the target, we want it to be one, and we need the Delta time so we can get the word Delta second for that and the interpose bit want to put it on two or whatever value that you want. And no this node on each frame will give us a value closer to the target value that is one, right? So we need to save that inside over force factor like this. And connect the execution pin to it. So we are smoothly change the force factor 0-1 if we are going forward. No, next thing that I want to check. Again, I want to check the input action in here, and I want to check. If it is equal to zero, it means we are not moving at all. So we need to smoothly change the force factor to back to zero. So if there is no input, this zero will happen. We can check it with the branch again, right? If there is no input, this true will happen, and again, we want to change the force factor smoothly. So we can copy all of this with Control C and Control V to paste it over here. But this time because there is no input, we want to change back this force factor to zero. That's it. Now, if this false will happen, it means the input I move forward, backward input is a value less than zero because it's not more than zero, it's not zero, so it is less than zero. So again, what we want to do we copy all of these control C control pay setting here in case of falls. It means we are going backward. We are heading S on over keyboard. That's why this IA move forward and backward is giving us a minus value. And with that, we need to change this force factor from whatever value it has to a negative value minus one, for example, right? That's all we need to do. Now, let's just say set if we had compile save what I want to do, I want to go to Aventq right in here and use a printes ring. So let's just use a print ring in here and show the force factor just connected to here, and it will automatically convert it to a string, so it will show it to us, right? Now, if you run over game, let's just look at it. If you run over game, right now, it's put in zero. But if we had told you, you can see it is smoothly going to one or closer to one, right? Now, you can see or ship hitting the ground and it will go backward, right? But let me see how we can fix that. We can just put the player start. Let me at F to see where it is. It is inside the water. We can bring it a little bit in middle, so it won't hit that easily, right? Now, if you run or game, you can see when we are in here, if you hit W, it will smoothly go to one and you can see it. And if we go backward, it will smoothly go to minus one. You can see that looks really awesome. But we are just changing a variable. With that variable right now, we can't rotate the blades. Now, let's see how we can use this variable to rotate the blade. 9. 08 Blade rotation: No for using that force factor to rotate our blade. For doing that, I want to go to Animation Blueprint. And in here first, we need to get that force factor in event graph, right? In here, first of all, I want to create a begin play event Blueprint begin play. And with this node that is called Try Get Pawn Owner, we can get over BP Ship, right? We can cast it. Two BP ship, right? So if this cast succeeded, it means we can right click on this BP ship and promote it to variable so we can get whatever variable that we want from inside of this BP ship. For example, if I go down, let me make this smaller. In here, we get our BP ship. First of all, we check if it is valid. So search for is valid, right? And if it is valid, we can get the force factor off of it. So search for force factor and get it. Now with that done, we can change the blade rotation value variable that we are using for rotating over blade with this force factor. But how we can change this blade rotation with it. First, we want to check if it is valid, change the blade rotation, right? Know how we can use this force factor. We can multiply this by some value, right? But with what value? We know that this force factor is a value between minus one and one. That's why we multiply it by some value. But what value? We want to get the blade rotation. Get the absolute of it, absolute, right. And each frame, we want to add to it, right, at like 15 unit. And if we just do that and connect these to blade rotation, what will happen? If we run over game, you can see it is always rotating, right? It is always rotating. Doesn't matter if we are moving or not. It will be always rotating and that doesn't look good, right? That's why we need to use this force factor. This we have, we can multiply it by force factor and connect the result to blade rotation. So if we are not moving and there is no input, this force factor will be zero, zero multiplied by whatever value, it will give us zero, and there will be no movement. But if we are going forward, this force factor will be one and one multiplied by whatever value, it will give us whatever value that it is, and the blade will rotate. But if we S on or keyboard, this force factor will be minus one minus one by whatever value, it will negate that whatever value, and it will rotate on the other way. Now, let's just say that. If you had compile save, and go to a level and run over game, no, you can see if I go close. If I had to you, you can see it is going forward. That looks awesome. And if you release it, you can see it will stay to zero, right? Again, if you go backward, you can see it will rotate the other way. That's cool, right? We are going forward and backward, and it does looks good, and it is rotating. One problem that we have in here, whenever we release WK just look at it. If we release WK, all of a sudden, it will go backward a little bit, right? So for fixing that, first of all, I want to increase this value. So every time the blade rotation increase more, for example, 50, right? So it rotates much faster. Next thing, go to BP ship, and in here for going to target zero whenever there is no input, I want to change the interpose bid to really big value like 20, right? Now, if we head compile and run over game, no, if you look at it, you can see the blades is rotating much faster. And if you release WK on our keyboard, you can see that does looks much better, right? That's better. We are finished with blade rotation. 10. 09 Going left and right logic: No, for actually going left and right. Let's see how we can do that. For doing that, first of all, let me delete this printer ring. For going left and right, first, we need an input. So let's just go to content drawer, go to Ship folder, go to input and right clicking here, go to input and create input action, and I want to call it IA Move left, right. Okay? And I'll click on it to open it. The value type, we want it to be Axis one D, make sure you save. And after that, we need to map it inside IMC sheep. In here, add a new mapping. We want to map DIA move left and right. We want to move left and right with D and A onward keyboard. So click in here, head D on your keyboard. No, the D will pass one through D input action. No, we need another one for A. So click in here, head A, and because we want to pass minus one, whenever we head A, we need to negate it with a modifier. So click in here, add the negating here, and it will negate it for us. Now with that done, if you go to our BP ship, let's just find some space, for example, down here, right click in here, search for IA moves right and left. We want the event, so choose the one that is child up enhance action event, right. First in here, we need to check if we are in water or not. So we get this buoyancy. If you are not in the water, we shouldn't be able to go left and right, right? So in here, we check in water body, right? We check that with a branch. Like this. After that, we want to check. If the speed is a little bit, we have some speed, but how we can get the speed. Forgetting the speed, I want to go to event tick and show it to you. So in here, I want to use a printer string, print a string. And in here, I want it to be persistence because we need this speed. I want to change the key to a speed, right? No, the string that I want to show, I want to create it with a format text. So in here, I can say a speed. Is equal to open and closed curly braces. And inside this, I want to say S for a speed, right? No, we can connect these two in a string, but we need to replace these curly braces with the variable that we connect to this Spin, right? So how we can get the speed. For getting the speed, we say get velocity. Okay. And with this velocity, we can get the length of it, vector length, X and Y, and we can show it with connecting it to the S, right? Now, if we head compile save and Runo game, you can see the speed right now is zero. If we go forward, the speed, you can see it will increase, and it is based on centimeter, right? So we need to first change it based on meter, for example, right? So for doing that, we can divide this by 100, so it will give us meter, right, and connect it like this again. Now, if you run over game, you can see if we hit, the speed will increase, and if we release W, the speed will decrease. No, one problem that I see in here is that we are releasing WK but it's moving. So we need to find a way to make it stop much faster. You can see right now we have a speed, right? So if you don't want to decrease the speed really fast, you can do that, but it will cause a lot of problem in future. So that's why I want to click on where Ship SM. And in here, I want to go to linear damping and angular damping and increase them. So for linear damping, I want to put it on 0.5 and angular damping, I want to put it on 0.1. Know with that, if you run over game and have some speed, let's just go forward. When we release WK, you can see the speed stop much faster. A speed decrease much faster, and we can go forward. And if we release WUKi, you can see the speed will decrease much faster. And we want that. It's more natural to do it this way. So now we have a speed. What I want to do with all of this, I want to grab all of it and right click on it and collapse it to function. And I want to call this function get speed. And this function, I want it to be pure. So we can just click on it and tell it to be pure like this. So with it, it's exactly like before, because we are not changing anything inside this function, we are just getting something. So that's why we can make it pure. It will be exactly like before. So if we run over game, you can see, again, the speed is showing it to us, right, and we can stop much faster. That's good. Now, let's see how we can use this get a speed to go left and right. So in here, if you go down in here, first, we want to check if you are in water, right? And if the speed, so we can get the speed again in here, get the speed. And if the speed was bigger than, for example, five, if it was bigger than five, you can go left and right. But how we can do it, this condition is just one. We can't connect both of these to here. There is a node that is called boolean, right? With this node, if we are on water and the speed was bigger than five, this will be true, right? This Boolean will give us true. But if one of these was false, this and Boolean will give us false. So that's why we are using this node. So again, let me explain it one more time. If we are in water and the speed was bigger than five, this true will happen. But if one of these was false, either we are not in water or the speed is less than five, this false will happen, and this is what these and boolean do. No, if this true happen, it means we can go left and right. Okay? But we want to check if we should go left or right. So we need another branch in here. And this time, I want to check this action value. I want to check this action value, the sine of it, so search for sine. If sine of this action value was bigger than zero, it means we are going right. But if it is less than zero, it means a negative value. We are heating A on our keyboard. So you can go left, right? Just with that, let's just use a print string for no print sring. And I want to say on this one, go right and I want to change the color of it to green like this. I want to add the key to here. It doesn't matter what you put in there, it will be okay. Just copy this printer string and paste it in here for going left. If false happened, it means the action value is negative value, so this false will happen, and in here, we want to say we are going left, the color of this one I want it to be red, for example. Now, if you hit compile save and go to a level and run if we hit D or A, nothing will happen, right? But if we hit W and hit D on our keyboard, no, you can see it says go right. And if we hit W and the speed is more than five, and if we hit A on our keyboard, it will say go left. So you can see going left and right is working fine with our ship. But no, we need to actually move it left and right. Let's see how we can do that next 11. 10 Use force local to go right: No, we need to be able to go left and right, and how we can do it, we want to do it with force because it looks more natural. So for doing that, let's just go to BP ship. And in here, in of these two printesing what we want to do, we want to add force to this ship SM right? The static mesh or ship. So add force, this time, we want to add the force at location local so we can change the ya of oversp going left and right with a force. So it is easier with at force at location, local. So just put it there. In case of true, it means we are going right, okay? And this node needs a location and a force. For the location because this is at force at location, local, this location and force need to be in local location as well. So let's see how we can do that. Know that we want to add this force at the location in front of our ship. Why? Because if we just add the force at the middle of this ship, it will go this way. But if we add the force at front, for example, at socket five, it will rotate this way, right? So that's why for going right, we want to get the local location of this socket five to add force to it to this way, so it will go right. Okay? So let's see how we can do that. For doing that, we need to first get our ship SM and get the socket location, get socket location. And the socket name is five for going right. We use socket five. But the problem with this socket location, it will give us the word location of our socket. But we know that this location needs a local location. So forgetting that for converting this word location to a local location, there is a node that is called inverse transform location. So search for transform location. This inverse transform location will transform or convert a word location to a local location. So use this inverse transform location. The location that we want to convert is this socket location, and this node for it to work, it need the ships word location as well. So we can get the word transform right, get for word transform of over ship SM, right? Now this inverse transform location will convert the socket word location to socket, local location. Now we have done it for the location, and it is good. But the force how much force we want to add, and what direction we want to add force. Again, if we go to here, we want to add force at this direction to the right vector of it, right? So for doing that, again, I need to get this ship SM, so let's get it like this. First, we need to get the socket. Rotation. Get the socket rotation five. Again, this rotation is rotation in word space. That's why we need to convert it to local rotation. Again, there is a node that is called transform rotation, and it's called inverse transform rotation. That will convert the word space rotation to local space rotation. So use this inverse transform rotation and connect these to rotation, right? And for it to work for it to give us the local space rotation of over socket five, we need to provide it with the ship SM transform, Word transform of right. Again in here, we say get word transform, get word transform and connect it to here. Now, this will give us the local rotation of our socket five, but we need the right vector. Search for get right vector off of this, and this right vector will give us the direction of where we should apply some force, so over ship, go to the right, right? But this get right vector is giving us a length of one. So that's why we need to multiply this by a big value. For example, 8,000, right, click on this one, change it to float and put 8,000 there. 8,000 is a lot, but let's just test with that and connect these to the force. With this get right vector, we tell it to which direction you should go, you should add force. And with this multiplier by 8,000, we say how much force you should apply to it. Now, if we go here to our level and run our game, can go forward and after that, go right. You can see it is going right. That's good. Let's just change the player start to face somewhere else with selecting it in here, head F, we will go there. I want to put it on this direction. You can see this forward vector in here. Let's just run and go forward, and now you can see, I can rotate over ship. You can see it's rotating. And I think 8,000 is too much. If I release D, you can see it is again rotating a lot, right? Because 8,000 is a lot and the rotation damping is not that much. So next thing that we want to do, maybe we should change this to 4,000, right, and click on or Ship SM and change the angular damping to 0.5 as well, so it won't rotate that much. Now, if you go to our level and run over game, let's see what will happen. If we go forward, we can go right because the force that we apply is 4,000, it won't rotate that much. But if we release D on our keyboard, it won't rotate anymore. You can see it. Again, we can bring it back to 8,000 again and test it, so you will see it better. Now, if you run our game, you can see we are rotating good. But because we have angular damping, more angular damping, it won't rotate that much. And if you release Don or keyboard, it should not rotate that much. And you can see the rotation is gone. No. That looks awesome. That looks beautiful. No, we want to go left. You try to do that yourself. We will do it in next video. 12. 11 Go lef right smoother: No for going left. Actually, it is easy. The only difference is that we want to add force to socket for this time to this direction, to left direction. Let's see how we can do that. For doing that, let's just organize a little bit because it is a mess right now in here. And with that, let me select everything. Hold control, you can select everything like this and bring all of this up here, for example, again, hold control. We want to bring all of this down so we have more space, right? And know with that we can select all of these Control C, Control V to paste it over here and connect the false to these that we paste in here, right? The only difference is that we need to change this socket name 5-4 for both of these, right? And the other problem that it has we are getting the right vector. We don't have a left vector. But what we can do with this right vector, we can negate vector. So just search for negate vector and do this, right? That's it. That's all we need to do. Let's just check if going left is working fine or not. Going forward, after speed is five, we can go left and you can see we are going left correctly. Maybe we should increase the force a little bit, but I think that is good enough. We are going right and we are going left correctly. For you to test it better, we can increase this value by multiplying it by two for both of them. This one as well, multiply them by two, right? And now if you run, it will rotate much faster. You can see it is rotating much faster. That's good. And we can go lift, as well. So let's see what will happen. If we go lift, you can see it is rotating much faster. But what I want to do next, I want to be able to rotate or ship faster if the speed is more. But if the speed is less, we don't want to rotate it much faster. We want to rotate it slower, and how we can do that, we can decide this force value that we have in here based on the speed. And how we can do that, we can get our speed in here and use map range clamp, right? And we can say, if the speed was 0-20, for example, change the force from, for example, 5,000 to 60,000, right, like this and connect it instead of this, right? No, if we are moving forward, slower, we will turn right or left slower as well, right? We can just use copy and pasting from this one to this one as well. Just control, see control, paste it over here as well. You won't see that much effect, but it will look more natural. If we go forward, the speed is less and we are not rotating that much. But when the speed is getting higher and higher, we will rotate more. And if I release W, you can see the rate of rotating will decrease based on the speed. You can see if the speed is less than five, we won't rotate at all, and it will stop rotating. You can see it didn't stop rotating. But if the speed get more than five, we can go left and right much faster. It will make rotating left and right much more smoother. You can see that looks really awesome and beautiful. 13. 12 Rotate ship gun: No, we are able to go left, right, forward, backward and all of that, but it's time to be able to shoot at something. There is a gun in front of our ship that we want to use it. So let's just go to a skeleton in here and zoom a little bit in here. You can see this is over gun. And what we want to do we want to use it to shoot at the stuff, right? So first and first, let's see what bones we need to change, we need to modify. For doing that, we have front gun joint. Let's just check that. This is for going up and down, so that's good. Now we have front gun, edge joint. And with that, we can look left and right, right? So with these bones, we need to aim at stuff, right? So first, let's see how we can modify these bones, and after that, we will use it inside or blueprint. So let's just go to animation Blueprint for over ship, go to anim graph. You remember we did change the rotation of some stuff in here for the blade, right? Right now, we want to change the rotation for our gun. As you can see in here, we want to change the ya up front gun He joint, and we want to change the pitch of front gun joint, right? So we know around which direction we want to rotate the stuff. First, in here, let me zoom in here to the gun so you can see it better like this. Make it a smaller. I think you can see it good in here. In here, let's just use one of these nodes, Control C Control V to paste it over here. We don't need to start from scratch, right? Connect the execution or pose into it and know first thing that we want to do in here, we want to change the bone to modify. First, we want to be able to look up and down. So we should use front gun, we joint, right? As we sit, we need to change the front gun, joint, the pitch of it. So for example, if I put 45 in there and head compile, you can see, no, it's 45 up, and that's it. We can create a variable for this one, promote to a variable, and I want to call it gun pitch. That with it, we are changing the gun pitch. For testing that, let's just head compile. Change the default value to zero in here and head compile. No, I can go to an in preview editor in gun pitch, I can change the pitch of our gun and you can see it's working. But one problem that it has, you can see it can go backward and we don't want that to happen. Let's see what is the limitation of this gun. If we go here, you can see it can go this way this much like zero, right? Let's just put zero. If you look at it, if it go less than zero, it will shoot over ship. So we don't want that. So the gun pitch minimum value should be zero. But the maximum value, let's just see if you go up, we don't want it to go more than this. So 40 I think is more than enough. But how we can use this value that we found in here, we can use clamp on it, so clamped it to a certain value. Only use clamp float, and I want it to be 0-40, right so it doesn't matter how much we are decreasing or increasing this value. I won't get past 40, right, and it won't get less than zero. You can see it will stay there. So you can see, we have some limitation on the gun pitch. It shouldn't reach the back of it, right? No, we done it for this one. What I want to do, I want to do it for the gun ya. For doing that, again, we can just copy and paste this one in here like this, connect the execution, pin to it. And in here, the only thing that you want to change is the bone, front gun, edge joint, right? And I want to just change the ya it as you can see in here, front gun edge joint. We want to change the ya rotation around the Z axis. So if you change these 245 and head compile, you can see it is working fine. If I put -45 and head compile, you can see it is working fine. So we can right click on it, promote it to a variable, and I want to call this one gone ya, right? That's it. Let's just test that out. First of all, I want to change the gun ya value from -45 to zero by default. So by default, it is -45. And after that in an in preview editor, I can change that. You can see, we can rotate it. So now, we have two variables that with those, we can aim at the stuff. Now, let's see how we can actually aim at the stuff. 14. 13 Gun camera: Now that we are able to rotate our gun, we need to have some camera. So with it, we can see where our gun is looking at, right? So for doing that, let's just go to BP ship. And in here, I want to click on Ship skeletal mesh. You can see it over here. I want to click on Ag and add a spring arm to it, right? Add a spring arm, and that's it. I want to cod this one Gun spring arm. So let's just call it Gun springar. And after that, with this spring arm, I want to click on AD and add a camera to it, right? And I want to call this one Gun camera, right? No, let's just go to Viewport. You can see by default, it is on 00 location for both of them, right? So what I want to do, I want to click on Gun Spring arm and because it is child of over sheep, skeletomsh, we can change the parents socket to the camera. Now you can see, where is the camera. The spring arm is a tip of over gun, but the camera is way back in here. 300 back, right? I want to change the arm length of over spring arm to 1,000. And now you can see, we can add some offset, for example, 500 and I want to reposition the spring arm itself by -800, right? Now, you can see it is at middle of over gun and I think we can see everything in this orientation, right? You can put the camera or a spring guard wherever you want. But I did test a lot with it, and I think this way is good. And when we move this barrel, what will happen, there will be a shake inside our camera as well that will make our gunfire looks much better. Next thing that I want to do, always, I enable use pun control rotation. No, a spring arm will rotate with the controller as well. Now with that, if we head compile, go to word and run our game, you can see, by default, the spring arm that we put there it's selected, right? We are moving, and we can move the shep as well. We can look around as well, and the ship is working fine. But we want to be able to switch between these cameras right now, we are just using the front camera, the gun camera. We want to be able to switch between them. Let's see how we can do that next we 15. 14 Switch between cameras: Know what we want to do. We want to be able to switch between the cameras, and how we want to do it, we want to do it with right most bottom. Let's see how we can do that. Let's just go to Content drawer in Input Holder, right click in here, go to Input and create input action. I want to call it IA AM. That's it. You don't need to change anything. You can just close it. Go to IMC ship and map it there. Add the mapping in here. We want to map the IAA and with it, let's just go down, expand this, click in here and after that, right click to put the rightmost button there. Head save, know we can go to BP Ship, go to event graph, and know we can implement the switching between the cameras. So right click in here, search for IAM, right. And in here, whenever we press right Mose button, this start will happen. And whenever we release most button, this complete will happen. So whenever we press rightmost button, we want to enable this gun camera, right? And we can do it with set active, right? And whenever we hold right most bottom, we want to activate the gun camera, and we want to deactivate the camera of our ship, right? So in here again set active and make it false, right? But whenever we release rightmost button, all of these we want it to happen, but in inverse, right? So let me connect these two here. The gun camera, we want it to be deactivated, but the camera over sheep we want it to be activated. Now, with that, licious head compiled save, go to our level, run no, you can see if I hold right most button, it is at gun camera. But if we release it, you can see, No, it is at ship camera. Again, right most button, at gun camera. And when we release it at ship camera. It's working fine, but one problem that we have is that by default, it is at the gun camera. We don't want that to happen. So what we can do about that we can take these lines for deactivating the gun camera and activating the camera of the ship. Control C to copy it and paste it at event begin play, like this. Now with that, if you head compile, save and go to map and run, you can see it is by default at the ship camera. But if you hold the rightmost button, you can see it did go to gun camera, right? That looks awesome, and we can release it to go to ship camera. 16. 15 Rotate gun with controller: No, we can rotate the camera around the gun, and we are switching the camera as well. But when we rotate around the gun, the gun it's not moving with our camera. So you can see, we are looking left right everywhere, but the gun, as you can see, it's not moving at all. We know how to move it. We did talk about it. We do it with gun yaw and gun pitch. So we need to calculate what the yaw and pitch of our gun should be. And where we can do that, we can do it in event graph. So let me first explain how we want to calculate it. You see? Our gun has a rotation and our camera or the controller has its own rotation. We need to calculate the difference between the rotation of these two and add it to the gun so it will face where our camera is looking at. And how we can do that, first of all, we need to get over ship and with it, we want to get control rotation. This is the rotation that our camera is looking at, right? And next, we want to get the actor rotation. This is the rotation that we're going already have. So no, we want to get the difference between them. We can do it with the Delta rotator, right? And we need to connect the control rotation to A and actor rotation to the B. No, it will give us the pitch and yo that our gun should have, right? Right click on here, split a stroke pin. It gives us roll pitch and yo, but we need just the pitch and yo. We can just set the gun pitch like this with the pitch that we calculate in here. And set the gun ya with the yacht that we calculate from here. Give it a execution pin and give it this execution pin from here. Organize a little bit. No, with Teton. Let's just head compile, go to our level, run, and let's just look at our gun. You can see we are moving over gun and we can look up and look down. And you can see it won't go less than zero. You can see and everything, I think, looks awesome, and we are looking left and right, but know that the camera is rotating. The gun is rotating. We need to find out where this gun is looking at. We will do it next. 17. 16 Gun line trace: Know what we want to do. We want to find out where our gun is looking at, actually. So for doing that, I want to go to BP ship and check where we are aiming. If we are aiming, we should check where our gun is looking at, right? So for doing that, I want to go here and with this, I want to see when we are aiming, right? How we can do it, we can check if gun camera is activated or not, right? So with that, we can check if you are aiming or not. So know what I want to do at every frame I want to check. First, if we are aiming or not. If you are aiming at every frame you want to check, where we gun is aiming at, where is looking at, right? So for doing that because I don't want to again mess up eventiq, I will create a custom event in here. So search for custom event, and I want to call it manage aiming. Right, manage aiming. And I want to connect it to a ventiq. So let me find Aventiq. We don't need this printer ring, so let's just delete that, and I want to put the manage aiming in here or aiming manager, whatever you want to call it, it is okay. Now in here, I want to use a branch first. Okay. And with that, get the gun camera and check if it is active, right? Is active. If it is active, in that case, we want to check if it is hitting something or not. W is aiming, right? In case of true, we want to use a line trace by channel. I need a start point and endpoint. Let's just see where should be the start point. If you go to our skeletal mesh, you can see there is a front gun socket at front of our gun, right? So we can check in forward of that, right? Forward of the socket where it's looking at, and how we can do it. Let's just go here, make sure you save everything always. The start point, we want to get the ship, skeletal mesh and socket. Location. The socket that you want to get its location is this one front gun socket, right? Control C to copy it and paste it over here, right? Now, this will give us the start location. But for the end location, what we can do, we can get the socket rotation and get the forward vector of that, right? So we can say, get socket rotation. And the socket rotation that you want to get, we did copy it. So let's just use Control V paste it over here. We need some space. So let's just put this over here. You want to get the forward vector off of it. And because this forward vector is a length of one, so it's too small. Or the end point is not enough. So that's why we want to multiply it by really big value. So right clicking here, change it to float because we want to multiply X, Y, and Z with the big value, right? Like 99999999, right, a really big value. And after that, we want to add the start location to this forward vector multiplied by a really big value to give it that offset, the offset of the start location, right? And this is our location. For you to see it, I will click in here and tell it to show a debuke for one frame. Now, let's just hit compile, save, go to our level and run. Right, no, there is no debuke line, but if you hit right most bottom, no, you can see O goon is finding out what it is looking at. You can see. I can look at the sky and you can see if it's hitting something or not. That's cool, right? And one thing that I want to do I want to increase this value in here, so we make sure it always hits something, right? Again, let's just go to map and run. Now you can see it is hitting everything always, right? It doesn't matter where we are looking at. Now, with that do, with this square at the end of this red line, we find out that it did hit something. If you go to a sky, if there is no square, it means it didn't hit anything. And how we can get we can get it with this out hit result. So we can just break it and check this blocking head. If it did hit something or not. First thing that I want to do in here, I want to right click on this blocking head and promote it to a variable. I want to call it Is it, right? That's it. And connect the execution pin to it. We want to see if our gun is hitting something or not if we shoot it, right? Next, what I want to do? I want to use a branch Okay. And check. If it did hit something, save the location that we hit that something. So we can promote this to a variable, and I can just call it impact point. It's more than enough. In case of true, we want to save the impact point inside a variable. But if it didn't hit anything, again, we want to save this impact point, Control C control V to paste it. But with what value? With the trace end, that end location, put it there. Now with that done, we know if we are hitting something or not, and we are saving where we are heading. If we are hitting something and it is successful, we will save that. But if you are not hitting anything, we will save the trace where it ended, right? This end location that we have in here, it will give it to us in here as well, and we can save it, right? That's it. We want to use all of this information to be able to shoot at some 18. 17 Crosshair: No, we are finding out where we gun is looking at or hitting at, but we don't have any cross hair for showing that. Right now, we are showing it with a D draw debot type, right? We show it with debo of Are engine. We need some crosshair. So for doing that, let's just go to Content drawer, go to Ship folder, right click in here, create a new folder, and I want to call it Widgets, okay? Widget. In here, right click, go to user interface down here and create a Widget blueprint of type of user widget. I want to call it DBP, crosshair. I'll click on it to open it. In here, the only thing that we want to do we want to add an image. And with this image, I want to change the image to cross hair. MD, this one, right? You can see it. Don't worry about the stretchiness of it. We will fix that. The tint color of it, I want to click on it and change it to a black one and change the a little bit so we can see pass through it, right, like this. You put whatever value that you want if you want to change the color or not. I will put 0.5 for the Alpha. That's it. This is our cross hair image. Now, we can go to our BP ship. I want to click on or ship SM, click on add and add a widget, right? Just add a widget and I want to call it cross hair, right? So first thing with this cross hair widget, we want to change the space from word to a screen so we can always see it and it won't go behind the stuff, right? The widget class that we want to create is called WBP crosshair, the one that we create together. And the size of it, I want it to be 100 by 100. That's all we need to do. Now, let's just compile, go to our level. Now, you can see the cross hair there. You can see it. We have the crosshair, but the positioning of it is not good. Actually, you can see we can see it when we are looking this way, right? So how we can change the position of our crosshair. Actually, it is easy. We can get our crosshair over here, right, get our crosser and set the word location on it, right? Set the word location on it with the location that we have the impact point, right? We can get the impact point from here and put it there. In both of these cases, this set word location for our crosser, we want it to happen. So let's just at compile, save and know if you run over game, you can see wherever or gone is aiming at the cross hair will be there. You can see it is at the middle end, it does look good, right? But one problem that we have, if you go here and we are looking at overship, you can see the problem. We shouldn't be able to aim at overship, right? So let's see how we can fix that problem in next video. 19. 18 Crosshiar visibility: Know what we want to do. We want to avoid being able to shoot at a ship. So let's see how we can do that. For doing that in here, after we check if we are hitting something or not, we need some space in here. So let me bring all of this to right like this. And in here, we want to check if this head actor that we have in here, if it is equal to self create self. If it is equal to self, we shouldn't be able to hit anything. So what we can do, we can check with the branch in here, and with it, if it was self, the true will happen, and we don't want to set this impact point. So hold control, dragon drop put it to falls. If it wasn't self, you can save the impact point and you can shoot there, right? And if it was self, what we want to do, we want to set our crosshair in here and set the visibility on it. So set visibility to falso, to fals. But in other cases in here, we want to set the visibility of crosshair to two. Now with that, the crosshair, which disappear whenever we are aiming toward overship, right? But let's just check it if it's work or not, right? In here, you can see if we are looking away, everything good. But if we are looking at overship, again, the crossir is not gone, and we can shoot, right? That is a problem. Why this is happening it's because if we click on our ship skeletal mesh and go to collision category and go to collision presets, it says no collision. So line trace will ignore it. We need to change this to vehicle, and we need to generate overlap and the head event as well for future uses, right? And after that, we need to go to line trace by channel and tell it not to ignore yourself. Now with that done, let's just head compile save, go to our level and run over game. You can see everything is working like before. But if you are facing toward ship, you can see the cross hair will be gone. That looks awesome, right? No, everything looks good, and we can shoot at our ship. So next thing that I want to do, I want to tell it to not show in the wg, right? Just put it non because we have a crosshair. We can use it. You can see. No, you can see whenever we want to shoot our sheep. You can see the cross hair will be gone. That looks awesome. That's beautiful. That's what we want it. 20. 19 gun fire conditions: No, based on the data that we have, we want to decide if we should be able to fire or not, what we want to check. Whenever we hit leftmost button, we want to see if we should shoot or gun or not, if we should fire or not. So for doing that, I want to go to content drawer, go to inputs, and in here, right click, go to input, create input action, and I want to call it IA fire, right? You don't need to change anything inside it. You can just map it in IMC ship. So in here, go up, create a new mapping. I want to hold shift click in here to claps everything, and after that, release shift click in here and it will expand all of these without expanding the childrens. Now, in here, we can map the IFFre, right? The IFFre we want it to happen whenever we hit Leftmost button. That's it. Click in here, hit leftmost button and it will put it there. Just with that, if you go to our BP ship in here, I want to be able to fire. So right click, search for IAFre right, the avent of it. Whenever we press the leftmost button, this start will happen. And in that case, we want to check some stuff with a branch, right? Let's see what we want to check. We want to check if the cross hair was visible. So we get the cross hair check if it is visible. It means it's not aiming at our ship, right? So in that case, we want to say fire. So let's just use a print tring and say Fire, right? And in case of falls, again, use another printer ring, say, not able to shoot, right? This one, I want to change it to red so you will see it better. Now, if we head compiled save and run over game, if I hit leftmost button, it says, Fire, right, because we are facing somewhere wherever we go, we can fire. But if we go toward our ship and hit leftmost bottom, it will say not able to shoot. That's one thing. But the next thing we want to check. If we are not aiming, we shouldn't be able to fire, right? No, we are not aiming, right? So let's see what we can fix that. In here, we can use a boolean like this to check if the crosser is visible and we are aiming. In that case, you can fire. So for doing that, we can get the gun camera, as you know, If the gun camera was active, it means we can shoot, right? So we check that as well and know if we head compile, save, and go to our level and run you can see, if I hit leftmost button, everything is working fine. If we shoot at the ship, it won't be able to do that, but if we go away and we are not at the gun camera, and if we hit leftmost button, it won't be able to shoot. Now the next problem that we have, when the main camera is active, we shouldn't be able to see that crosser. So let's see how we can fix that. For fixing that, we can go up until we see the I aim. Whenever we aim, we want to make the cross hair visible. So set visibility two. Let me connect these to here. True. And whenever we are not aiming, we need to set the visibility of our cross hair to false. So make this pulse. Now, let's see what will happen. If we compile save, and if I run our game again, you can see if hold rightmost button, we can see the crosshair, but if you release it, no, you can't see it. Okay? No, you can see it because we hold rightmost button, you can see the crosshair. And if you release it, you want to be able to see it. But one problem we have. First time that we play our game, you can see the crosshair is in here. So by default, we want to make it invisible, right? So we can go to our BP Sheep, click on crosshair and go down until you find the visible down find the visible in there and make it false by default. Now, if you compile, save and go to our level and run over game, you can see by default, the crosshair is not there. If you hold right most button, the crosshair will be there. And if you release it, it will not be there, right? Everything is working fine. If you are hitting the ground, everything okay, but if you are hitting the ship, it won't be okay. And if you are in the main camera, we won't be able to shoot. That's working fine. We can just get rid of the printer rings. We don't need that anymore. We know when we can shoot and when we shouldn't be able to shoot. So delete that and know we are ready to shoot or gun. 21. 20 Ship projectile: No for firing or a weapon, we need a projectile. Let's see how we can create that. For creating that, I want to go to content go to blueprints and in here, right click create a blueprint class of type of actor, and I want to call it BP ship project tile, right? I'll click on it to open it, and in here, first thing that I want to add is a sphere. Okay? That's it. And I want to make this sphere as a default syn root. Next thing that I want to do, I want to create a material for this sphere so it will look red. So let's just go to content drawer. I will create it just over here. Right click create a material, and I want to call it red. Do click on it to open it. And in here, we can hold tree and hit leftmost button to create a constant tree vector or you can just search for constant tree vector, this one. With this, we can change set a color. So for example, let's just choose red. This color, right? And if you connect it to base color or sphere will be red. Of course, it's not red. Let's just change that. If the blue is zero and green is zero, and red is one, it means it is red. That's it. No, we want to have some emissive color or glowiness, right. For that, we can multiply this color with a really big value like 400 maybe and connect it to emissive color. That's it. I will glow a lot. If we head save, we can use this material. So let's just go here, click on sphere and change the material to red. Just search for it. I didn't find it. Let's just go down until we find it, and that's it. This is the red. Now, you can see it. Next thing that I want to do, I want to change the size of this sphere in all directions. So I will click in here to change the size 2.25 because it's too big for our gun No. Next, I want to go to collision section. So let's just go down. And in this collision section, I want to click in here, change it to custom. I don't want this projectile to block the visibility and the camera, so let's just make it ignore them, but block everything in here, and that's all we need to do. Let's just head compile, save. Now, next thing that we want to do. We want to add the projectile component. Click on AD search for projectile movement and add it there. No, with this projectile movement component, if I go up, you can see, I can put initial Speed and MaxSpeedF example, I want to put 20,000 for initial Speed and 50,000 for maxspeed. That's it. Let's just test that to. If we go toward the X because you know that the X is forward vector, we can simulate it. No, you can see it's working fine. Again, let's just look at it. That's really cool. This is our projectile and it's moving. Now, let's see how we can spawn it whenever we hit leftmost button. Let's just go to BP ship. And in here, if we should be able to fire, this tree will happen and we can spawn actor from class. Which class it's called projectile. So let's just put ship projectile there. It needs a transform spawn transform. So what I want to do for that, if I go here, I want to spawn it a tip of or gun. So this socket is really important. HadfT on it to rename it, control C to copy the name. And now we can go here and get a skeletal mesh of asp, and in here, get socket transform. And the socket that you want to get is called front gun V socket, the one that we copy together. Now with that, we can put it there. If you have compile, save and know if you go to our level, you can see, I can shoot it. You can see, everything is working fine. But the problem right now is that when it hits something, nothing is happening. There is no sound at all. So no, we want to check. Whenever it hits something, do some visual fake, some sounds as well. Let's see if we can do that. And next 22. 21 Ship projectile VFX: No, we want to add some visual effects to our projectile whenever it hits something. So let's just go to Ship Projectile inside its event graph. We can tell it to create event when you hit something, right? So click on Projectile movement, go down in here until you see the Projectile stop. Click on it. Whenever it hits something, this will happen and we will have some impact results. So let's just break it. Like this. First thing that when it hits something we want to do, we want to apply some damage. So if it hits something, it should apply some damage, right? So let's just do apply radio damage because it is a artillery, right? So it should explode, and that's why we use apply radio damage. With that, we can just put a base damage. For example, let's just use 10,000. The location that you want to create this radial damage is the impact point. So let's just put it there. The damage radius, I want to put it on thousand, right. And next, the ignore actor, what I want to do, I want to create a self reference in here. So search for Rf, get a reference to self, right, and make an array with this, make array. That's it, and we can connect it to ignore actors, right? And know the damage causer, we need to set that as well. So connect the damage causer as well. No, it will apply damage to whatever surface that it's hitting. That's cool. For you to see it better, what I want to do, I want to create a draw debug. Sphere, right, for that. The location of this sphere, I want it to be exactly this impact point that we set for aplo radial damage. So I can hit double middle most to create a re root node and connect this from here to here. No, it's more organized this way, right? No, the radius I want it to be the same radius that we have it in here, so 1,000. That's it. Now, the duration, I want it to be, for example, five second thickness. Let's just put ten in there so we can see it. Now, for the color, let's just use a red color. So again, it will be easier to see. Now, if you he compile, say it, go to a level and run over let's just see. If we shoot something, you can see. Whenever it hits something, it will show a sphere that show that in this sphere, it will apply some damage. It's for visualization. At the end, we will delete that, but you can see it's working fine. Next thing that I want to do, let's just go to Ship projectile again. I want to add some explosion whenever it hits something. So in here, I can say spun system at location. And the location that you want to spawn it, again, is this location. We can, again, double middle most in here to create a reroute node and connect it like these two location. For the rotation of it, I can go here and get the impact normal like this and make a rotation from its eggs, right? And connected to the rotation of the system, the Niagara system that we want to spawn. We don't need to change the scale at all. Everything by itself, it's good. No, we should choose the Niagara effect. It's called Niagara dust explosion. One, if you have another explosion for Niagara, you can use it, head compte, save and know if you run we game, let's see what will happen. If we shoot. No, you can see there is a explosion there. Whenever it hits something, you can see it. That looks awesome. If we can go close to this, for example, ground, you will see the explosion better. You can see I'm closer and I can shoot. Now, you can see the explosion. Good. We have a explosion that we can use. That's good. No next thing that you want to do for this ship projectile, we want some sound. So in here, I will drag and drop search for pa sound. At location again. So we want to spawn a sound whenever it hits something, right? What sound? Let me click in here? It's called E grenade explosion. That's it. For the location, again, double middle most on this location and we can just dry and drop it, put it over here, so we will be more organized, right? Head compiled, save No. Let's just go to our map and test that out. If we shoot know, there should be explosion. You can see it. But the problem is the explosion is far away from us, but we can hear it completely. That shouldn't be happening, right? If it's far away from us, we shouldn't be able to hear it at all. But if you just shoot overhear, for example, when it hits something, it's like it exploding near us. So how we can fix that we can go to Content drawer. I want to go to Ship folder, right click in here, create a new folder. And I want to call this one sound. Inside this, I want to go to audio and create a sound attenuation. To tell it if you are far away from us, don't play it for us in that level, right? I will call it essay for sound attenuation and I will call it explosion. That's it. Don't click on it to open it, and you can see in here we have inner radius. So if you are inside that inner radius, it means we can hear the sound completely. I want to change that to 2,500, and the follow of distance, it means if you are inside this flow of distance based on the distance that we have to the middle of the sound, we hear it less. If we are not in this fall of distance, we won't hear it at all. And I want to change the value of it to 15,000, right? Now with that done, we can go over BP projectile and expand this pon sound at location and change the attenuation setting to SA explosion. That's a head compile, save, go to over map, run over game. Now, if we shoot in here, for example, you can see, we can't hear it. But if we get closer, to one of these grounds, you will see the effect better. If I shoot know, we can't hear it, but you should hear, we can't hear it because it's too away from us. You can see? No, we can't hear it because it did explode near us. You see? It did explode near us. But if we go away like this, we won't hear it at all. You can see. But if we hit near stuff like this, we will hear it a little bit. That looks awesome. But one problem that we have is that the projectile is not destroying after it's hitting something. For doing that at the end of this execution path after we spawn sound at location, we can say destroy, right in here. Just say destroy whenever the projectile stop moving. Again, let's just test settled. If we go to over level and run over game, let's just get close to one of these areas. And now, if you shoot, you can see it will be deleted after it hits something. Let's just shoot, can see, we are shooting something, but it's not there anymore like before. And we can hear the sound a little bit. You see. And after this red square is going, you can see that red sphere won't be there. You can see it will be deleted, and it will aploi damage as well. That was it for Ship projectile. 23. 22 Fire calculated projectile: No one problem that we have. Let me show it to you. If you run over game, you can see we are aiming at that point inside our level, right? If we shoot, because our projectile is physics based projectile, that's why it will go like arc and it won't reach that position. So that's why we need to increase the initial speed. Let's see. If we go to Ship projectile, we can just click on projectile movement and increase this by adding just zero or multiplying it by five, for example, and multiply the max speed to five as well. Now, let's just see if we are hitting something or not. If we run over game and shoot there, let's see. You can it's happening, but it's going so fast that it doesn't look that awesome. It doesn't look beautiful. So how we can fix that. I want to bring back these 22000550000, right? In this way, let's just check it one more time. You can see it does look better because we are seeing it, but the problem is it's not hitting anything. There is a node inside Aerial engine that can calculate how much speed this projectile should have to reach that point that you want to hit, right? So for doing that, first of all, we want to check IO gun is hitting something, if it's hitting something with the line trace, we should calculate what the speed it should have, so it will hit that spot. But if it is in the sky and the line trace doesn't hit anything, just use whatever speed, like 20,000. It will be okay, right? No, for doing that, we have something inside or manage aiming, right? In here, we save if we hit anything or not. That's where we want to use it. In here, before spawning or projectile, what I want to do I want to check with a branch like this and check if it is hitting something or not. If it didn't hit anything, just use a normal projectile This projectile that we create together. But if it hits something, this true will happen. And again, we want to spawn something. But before doing that, we want to calculate the speed that that projectile should have so it will reach that impact point, right? So in here, there is a node that is called suggest projectile velocity, right? That's it. That's what we want to use. It needs a start location and end location. For the start location, we can just use this sort location for our line trace that we had from before. So copy it and paste it here for the start location, right? But the end location, we can use impact point because we want to hit that impact point, right? Now, we need to put a launch speed. For example, let's just use 20,000, right? And that's it. What it will give us, it will give us a toss velocity, the velocity or speed or initial speed that or projectile should have to reach that impact point from the tip of over gun, right? This will give us that velocity. But the problem with this projectile that we create, we can't set this toss velocity there. So we need another projectile that can do this kind of stuff. So let's just go to Content drawer, go to Blueprint and duplicate this projectile that we have. And I want to call it ship projectile with a speed, right? So we can set the speed in it, don't click on it to open it. In here, at its begin play, we want to get this projectile movement and set the velocity on it, set the velocity or a speed on it, right? But with what value? The value is that suggested value that we have inside the BPI ship, right? So in here, how we can get that, we can just create a variable of type of vector, and we can call this speed or velocity, whatever you want you can put in there. The important thing is to make it in sense editable and expose on a span so we can set it outside this blueprint, right? Next, we can just connect it like this. After that, in projectile movement, we don't need the initial speed. We don't need the max speed because with this velocity, it will works, right? No, with this new projectile that we create, let's just go to BP shape after calculating the toss velocity that we projectile should have to reach the impact point, we can spawn actor from class. But this time, we want to spawn the projectile with the speed, right? With that, you can see, no, we have a pin in here that it says speed, and we can connect this toss velocity to a speed. It needs the span transform, and we can just use this span transform that we have for the last projectile. It's exactly the same as before. Sit over here, make some space and connect the span transform to a span transform, right? That's it. Now, if you hit compile save and go to our level and run, no, you can see if I aim at that part and hit leftmost bottom, you can see the speed is changing, so it will hit that spot. Doesn't matter where we are heading. The speed will be changed, so it will hit that spot. You can see it how accurate it's doing it, right? That looks really awesome. And we want that to happen because it's really hard with the ship to hit something far away, right? But with this method that we have, we are always shooting at whatever we are aiming. So that looks awesome. But the next thing that you want to add whenever we fire over weapon, there is no visualization. There is no sound to tell us that you fire your weapon. So in Mexico, you will 24. 23 Gun fire VFX: No next thing that you want to do we want to add some visual effects to firing the weapon. So let's see how we can do that. For doing that, I want to go to BP ship, and in here, wherever we are firing or gun. In here, we are firing or gun. So what do you want to do at the end of everything? Let me bring all of this over here. At the end of everything, we want to have some visual effects, some sound as well, right? So first thing first in here, I want a spawn system attached. This time, we want to use attached, so it will attach to the socket that we want. So whenever we move over gun, it looks more natural. In both of these cases, we want to have a spawn system. In both of these cases, we are spawning a projectile and firing over weapon, right? The system that we want to use in here, if you go down, it's called NS west ship front gun. Just choose that there. Now we want to attach it to something. What we want to attach it, we want to attach it to the ship a skeletal mesh. So put the ship a skeletal mesh to attach the component, and know we want to tell it the attach point name, the socket name. Where do we want to attach it to the socket at tip of a gun, right? So controversy to copy this and paste it over here, right? Now with that done, let's just head compile save, go to a level, run, and know if we shoot. You can see there is a No graphic whenever we shoot and you can see if you move over barrel, just look at it. There is a smoke getting out of it, and that looks awesome, right? Can see. So this is the first thing that you want to add to our gun. But we want to add sound as well. For the sound, we can just say spa sound at location, right? And the sound that we want to play is called ES cannon fire. Just put it there for the location. We can get our ship and get socket location. And the socket location that we want to get is the tip of over gun that is called front Gun socket Control C copy from here. We can just paste it over here and connect it like this. Know with that, head compile, save, and know if you run over game, let's see what will happen. If we shoot. Now you can see, we can hear some song. That looks awesome. That sounds awesome, right? No, the next visual face that I want to add to this gun is the recoil of the gun. So whenever we shoot over gun, this gun should go back and forward like this, right? Let's see, we can do that. Next 25. 24 Gun recoil: No next thing that we want to do, we want to have a recoil system. And for doing that, let's just first go to ABP ship, and here, go to anim graph. This time, we want to change the position of the barrel of the gun. This one. So first, let's find out what is the name of this bone. For doing that, click in here to go to a skeleton and find the gun itself. Let's just click on front gun, H joint, move it. You can see it's moving whole body. But if you click on front gun, V joint, with moving this backward and forward, we are creating some recoil effect, right, like this. That looks beautiful. No, we know the name. Front gun, we joined. Let's just go here and move it. So in here, make some space. And in here, again, we want to use modified bone, and this time we want to change the translation. So we don't need this rotation. We can tell it not expose it as pin. We don't need a scale. Don't expose it as a pin. We need just translation or position, right? Click in change it to add to existence, so we add to the position of it. And the translation space, I want it to be in bone space, so it will be based on its parent bone, right? Know what translation we want to change. If we go here, you can see we grab the X and bring it out and inside, right? So we need to just change the X. So we can right click in here, split the striking and right click on translation, promote to variable, and I want to call it recoil. Value, right, or whatever you want to call it. Now, if you had compile, you can see it give us a warning and it says, you must pick a bone. We did forgot to pick a bone in here. So bone to modify, you know that it is front gun joint. With that, if you had compile, we can go to preview editor and change the recoil value. You can see it will go inside site, inside Osit. And that's what we want to do, right? Now, let's see how we can calculate this recoil value. For doing that, I want to go to BP ship, and whenever we fire over weapon, you can see whenever we fire over weapon, at the end, we want to create a timeline for changing the position of our gun, right? So we have some recoil animation. So in here, I will search for timeline, and I want to call this timeline recoil, right. Whenever we fire over weapon, we want this timeline to play from start. So hold control, grab this and connect it to play from Start. And no doubt, click on this recoil. We want it to happen 4.3 second. Add a track of top of flow track, and I want to call it recoil. Value, right? And inside it, we want to have some keyframe. So right click add the keyframe at time zero, we want it to be zero. That's it. No, again, right click add another keyframe at time 0.1, we want it to be one, right? And again, at another key frame this time at time 0.3, we wanted to go back to zero. Now, if I click in here and here, you can see it better. For it to be more smooth, we can grab all of them, right click on one of them, and change it to Auto. So we have some curves. You can change these curves as well. For example, I can click on this one and bring it. No, you can see the curves. And if the value is not one, you can just change it to one over here, right? So just with that, it will give us a value on its outside and it's called recoil value, right? So we can promote these to a variable, and recoil value name is more than enough. And with that, if we had compile save, we can get it inside the animation blueprint, event graph, right? Again, at the end of all of these, we want to get our BP ship again and get the recoil value from it, get recoil value. And save this recoil value that is coming from BP ship, inside the recoil value variable that is inside animation blueprint, connected like this and know the recoil value that is in BPship is connected to the recoil value variable that is inside or animation blueprint. Now with that done, if you go to Anim graph, you know that the recoil value right now is a value 0-1. That's not enough. We want to move this more than that, and how we can do that, we can multiply this by some value. For example, if I put 200 and connect it to here, let's see what will happen. You can see it did go where. I can see it. And all of a sudden, you can see that it's not there because the recoil value in an in preview editor is really a negative value. If you put it to zero, you can see it will be there. And if you put it to one, you can see it's going forward. So that's why we need to change this multiplication two -200. No, let's just compile. No, you can see if I put one in there, it will go inside, and if I put zero in there in there, it will go outside. You can see this value is too much. Let's just change it from -200 to -100. And now, again, let's just test 0-1. You can see 0-1. That looks awesome. It will go to one to this point, and after that, it will go back to this point. Now, let's just test that inside over level. If you run over game in here, whenever we should look at the barrel of the gun. You can see it did go back and forward. Camera is going with it as well. Why the camera is going with it because we set the camera to be as a child of this barrel of the gun, right? So you can see, we have some effects with our camera as well. But the barrel of the gun itself, it's going back and forward. You can see we have a cuffix in here. That looks really awesome, beautiful, and it's working fine. 26. 25 Gun Fire rate: No we have a problem. Let me show it to you. If you run over game and let's just hit leftmost button a lot. That doesn't look good, so we need to limit that and how we can do that, we can do it with this recoil system that we have. We can just create a variable of type of Boolean and I call it can shoot. Okay? And when this timeline is happening, we want to set the can shoot to folds like this. But when it's finished playing, it means the recoil is finished and we can set the can shoot to true. No, with that variable, we need to go at the beginning of this execution path where we are checking if the gun camera is active and crosshair is visible, we want to add another pin and check the can shoot. If all of these states are true, we can shoot. But if one of them is not true, we won't be able to shoot. And now, we're doing that, we need to change the default value of this can shoot true. So the first time it can shoot, head compile save. No go to your level and run your game. No PC. We can shoot. But if we try to rapid oh. You can't do that. Every 0.3 second, we can shoot. That's more than enough. 27. 26 Gun camera zoom: Next thing that we want to do because our sheep want a fire far away from us, we need to be able to zoom a little bit. So for doing that, I want to go to content drawer, go to inputs because we need an input with middlemost, we want to zoom. Right click in here, go to input, create input action, and call it a Zoom. Dot click on it to open it the value type, you want it to be axis one d. That's more than enough. You can just close it. Actually, you can close some of these up for no, and we don't need this attic mesh. Just go to IMC and add new mapping, right? The new input action that you want to map is called IA Zoom. So set it there. After that expanded in here, we want to go to Mos and choose Mos wheel aces, right? Headsave no we can use it inside our BPC. Find empty space down here, for example, and search for IA Zoom, right? First, let's see what value it is giving us with the print est ring, right? Just look at it. We had compile, go to our level and run, you can see if I go here and we middle most Zoom, you can see if I go up with the middle most, it will give us one, and if we go backward, it will give us minus one. So that's good. Now, we want to see how we can change the gun camera Zoom. How we can do it, we can get the gun camera and get its field of view. That's it, and we want to add to it. So let's just add this action value to it, right? And after that, I want to clamp it so it won't zoom a lot. We want to zoom a little bit. For example, 60-120, we don't want to less or more than that, right? After that, again, we can get our gun camera and set field of view on it, right? That's it with this value. And it need execution pin so let's just give it that. Now with that down, let's just compile, go to our level and run our game. And no with the middle most, you can see, I'm zooming and I'm on zooming. Can see that looks really awesome. We have two problem with this zoom. Whenever we rotate the middle mose forward, it will zoom and when we rotate the middle mose backward, it will zoom. This is the first problem that we want to fix. Next, it takes too much time to zoom and zoom. That's another thing that you want to fix. First problem for zooming and on zooming, we can just multiply this by a minus value minus one, for example, and connect it to here to negate it. Of course, we can just negate it inside over input action, right? But let's just see how we can do it just in blueprint, right? Now, in here, we can zoom and on Zoom with middle most, right? Easy. But another problem is that it takes too much time to zoom. So let's see how we can fix that. For fixing that, instead of multiply this by minus one, I want to multiply it by minus five. No, it will zoom much faster. Let's just go to level. And in here, if we zoom, you can see it will zoom much faster. Zoom and on Zoom, much faster. That looks really awesome. No one problem that we have. Look at it. If you are zooming right like this, and we release right moose button, and again, hold right most button, it will go to that zoom level. We don't want that to happen. So what we can do whenever we release rightmost button, we need to change the field of view to 90. Default one. If we go to gun camera, you can see the field of view by default is 90. So we go here whenever we release rightmost button, this complete will happen, and at the end in here, we want to get our gun camera and set the field of view on it, field of view, right? To what? 90 back to 90, right? Connected like this. No, let's just statue. If we run over game, now you can see, I can zoom and after that, release right Mouse button. And again, hit right moose button, you can see it will go back to Zoom that we wanted to have again. We are zooming, shoot and now you can see, it's working fine, and it's beautiful. Let's just move a little bit. Shoot. You can see. That looks really awesome. Beautiful. 28. 27 Anti ship blueprint: No, or ship is good, but we need some enemy. And for doing that, we have a artillery that we want to use it as anti ship. So let's just first import the files and after that, create an anti ship artillery. So for doing that, there is a zip file in description of this video that is called anti ship. Just download it. Put a tunnel this after that, open it. And in here, we can just drag and drop this antihe folder to the desktop and it will be extracted. Now, we want to import it in our real engine. Click on Content drawer, click on content folder, right, click on it, show it in Explorer. And drag and drop this anti ship folder there. It should be exactly like this. The path should be exactly like this. You shouldn't change the name or the position or the location of this anti ship folder in Windows Explorer at all. If you want to do it, you can just do it in Argo Engine. No, let's just go to content drawer. Let's see. There is no thing in here, so we need to close ARL engine and open it again. No ARL engine open again. And you can see in Anti Ship folder, there is asset folder there. If you go to vehicle east and you can see it over here. The keletal mesh. Let me open it. You can see it over here. We can use this to shoot at ship. No, I want to close this. I want to close these ones as well. We don't need them anymore. This one has will, this one has will. We need just the ship, right? No, with that done, I want to go to Anti Ship folder in here, right click create a new folder in here, and I want to call it blue print. Do click on it to open it in here, right, click Create a blueprint class of type of actor, and I want to call it BP t sheep, right? Do click on it to open it. And in here, first thing that I want to add is a skeletal mesh. So add a skeletal mesh. I want to put it as default scene route, and the skeletal mesh that I want to choose is called SK East Rt, right? Just put it there and you can see it. And this is our artillery that we want to use. Let's just go to our level. And where I want to put it, let's just put it at middle in here in here, drag and uro one, dated. So it will face outside, right? Hold out and drag on one of these axes, and it will create another one, and we can put it over here. Rotate it a little bit this way, maybe, right? Let's just add another one in here. For example, these artilleries are fighting against enemies on this small island, bring it down a little bit, bring it up, actually. That's it. Now, we have three artillery that can hit 29. 28 Box trace: No first thing that you want to do with this anti ship blueprint is that we want to find out the target, and what is the target? Is our BP ship. How we can get our BP ship. In here at the begin play, what we want to do? We want to get the player pawn, with this get player pawn, we can cast it to BPP ship. And if it was successful, it means the ship is inside or level, so we can right click on it, promote it to variable, and we can call it target. Now with that done, we need to check if it is in our line of sight, if we can shoot at it, right? If it's at front of anti ship, if the target is at front of anti ship and how we can do it, we can do it line trace, but I want to show you a new thing. In here, in each frame, I want to check if the ship, if the target is at front of us, so to see if we can shoot at it or not, right? So for doing that, I want to do it in every tik. That's why I need to create a custom event down here, and I want to call it lineup site manager, right? And I want to connect it to the eventiq. So search for Lineup site manager. And know whatever we connect to this custom event, it's like connecting it to eventiq. With this, what I want to do I want to use box trace by channel. It is exactly like line trace by channel, but the difference is this box trace has a thickness. We can change the size of it. Now with that done, it needs a start location and end location. The start location, I want it to be a tip of this gun. For finding the skeletal mesh of this gun, we can just click on the skeletal machine here. And click on open or this magnifier glass in here, and it will open up the skeleton mesh for us. I'll click on it to open it. And this is our skeletal mesh. We can open up the skeleton as well, because it's easier to work with the skeleton in these cases. We want to socket at tip of or gun. If you go here, you can see the gun joint socket is at tip of or gun. That's good. We need the name of it, click on it, Head f two to rename it Control C to copy it. And now in here, go to Avent graph. For the start location, we can get the skeletal mesh, and we can get the socket location off of it. The socket location that you want to get is gun joint socket. Control past there. This is the or start point, but the end point, we want to see where this gun joint socket is facing at. So for doing that, again, we can get the socket rotation this time. The socket rotation that you want to get is gun joint socket, at tip over gun. And with this rotation, we can get the forward vector off of it, right? And because this forward vector is a length of one, we need to multiply it by a big value. So let's just right click and change this to float. Like 100,000. That's it. This will determine how much further or anti ship can hit the ship, right? So this value is important. You need to change it later. Next, we want to add this start location as an offset to this forward vector multiply by 100,000 to give us the end location. Node for the half size, I want to change it to ten, ten and 100 for the Z. In this 100, maybe you need to change it later, but for now, it is more than enough. Now, for you to see it, I want to change this draw debc type to one frame. Now with that, if you had compile, save, and go to a level, you can see there is three box traces. That is under the water, right? If we go forward, we won't be able to see it, but if we go, you can see the line traces correctly. It's going under the water. So what is the problem? Our anti ships are facing this way. So we need to change the rotation of our anti ship so it will face a ship. So let's see how we can do that next. 30. 29 Anti ship gun pitch: We want to be able to actually change the rotation of our gun so it will look up. Let's see what we can do. For doing that, if you go to a skeleton, let's just find the gun joint, right? And this gun joint, if you can rotate it, you can see, this is not the way to do it. After that, we have the horizontal joint, right? If we rotate this one, you can see, with this, we are rotating it correctly. So what you want to do, we want to change the horizontal joint so it will face the ship. And for doing that, we need the animation blueprint. So let's just go to content drawer, go to Anti Ship folder, go to Blueprint. And here, right click, go to animation and create Animation Blueprint for a scale East art right? Head creating here and I want to call it ABP anti ship. And don't forget to set this animation blueprint for our skeletal mesh over here. Let me make this a little bit bigger and choose it over here, ABP anti ship. Now with that done, let's just open up the animation blueprint. And in here, like always, we need mesh, space, ref pose, so we will have all the information about the bones. We can connect it to output pose, and that's it. No next thing that we want to do, we want to modify the bone. Modify bone. And the bone that you want to modify is called horizontal. So let's just search for it. Horizontal joint. That's it. Now what you want to change, we want to change the rotation. So we don't need this translation, don't expose it as pin. We don't need this scale, so don't expose this as pin. We want to change just the rotation, and we want to add it to existence. And the rotation space, I want to change it to bony space as well. No, let's just right click on the rotation and split a stroke pin. Which one of these you want to change? If you go here, you can see it is this green one that is called pitch rotation around the Y axis. So with that, we need to create a variable to change the pitch. In here, right click promote variable and what I call it gun pitch, right? And we can just put it in here, compile. Now in in preview editor, let's just test it. You can see, we can bring it up and down, and that's really good, right? Now how we can calculate this gun pitch. For calculating it, I want to go to BP Anti ship and we have the target. We need to get the rotation from over untiship to the target, and that will be the rotation that our anti ship should have, right? So for doing that, again, I need to do it on each frame. That's why I want to create another custom event for it, so we don't mess up this eventique. So let's just go down in here, right, click Search for custom event and I want to call it Gun direction. Manager or whatever you want to call it. I want to connect it to Even tique. So in here, let's just search for gun, direction manager, right? It will happen every frame. So no, with that done. First thing first, we need to get over target and check if it is valid. So search for is valid in here. If it is valid, we need to find the rotation from our Aunt to the target, right? So for doing that, there is a node that is called find Look at rotation, right? I need a start point. The start point is get actor location, right? This get actor location will give us the location of our anti ship. Next, it needs a target location that we can get it from our target location, actually, right? We can get actor location of our target and connected to the target. This is the rotation that our anti ship gun should have so it can hit the ship, right? Now, we want to calculate the difference between this rotation and the rotation that our anti ship already has. The rotation that our anti ship already has, we can get it. We get actor rotation, right? With this, there is a node that is called Delta rotator, right? And this Delta rotator will give us the difference between the rotation that where Aunt ship should have, so it will face the target and the rotation that it already has. No, it will give us roll pitch and yaw. So right click on it, split the rock pin, you can see it. The only thing that we need is just the pitch. So right click on it, promoted to variable. I want to call it gun pitch, right? And it need the execution pin. So let's just give it that like this. No, we did calculate the gun pitch. Let's just see how we can get it inside our Animation blueprint. In Animation Blueprint, go to Avent graph, and we need a begin play in here, begin play, right. And because the owner of this animation blueprint is just an actor, that's why in here, we should get on actor. With this Gon in actor, we can cast it to BP anti ship, right. And with that, we can get the gun pitch variable. So for doing that right clicking here, promoted to variable, and we can just call it BP Anti ship. Now, with that done, we don't need this target pawn owner. We can just get this BP Aunt ship that we get over here. And first thing first, check if it is valid, right? And if it is valid, we want to get the gun pitch off of it. So in here, we did calculate the gun pitch. Inside or BP anti ship so we can get it and save it inside the gun pitch that we have inside or animation blueprint. So let's just connect it like this to is valid. Now with that one, if you run Word game, you can see, again, it's facing down. But for testing that, I want to click on the player starting here, bring it up. And RunwGame you can see it is looking up. You can see it is looking up, but it's not facing over ship at all. How we can fix that we can just go here in the animation blueprint in Anim graft. We can add to this gun pitch, add five unit to it like this. At five Unit and after that, connected to the pitch. Now, if we compile and if we run or game, you can see, it's facing us better. And if we hit the water, you can see we can go forward, and it can hit us, right? So that's really good and beautiful. But why this problem is happening. If you go to BP anti Ship, you remember we get the actor location and we get the target actor location. What it is giving us. Let's just see. For the untiship, the 00 location of this auntieship is down here. That is the first problem. And if you go to auntieship in here, again, the 00 location of this one is here. So we need to change the sort location from here. So that's how you can fix it. But adding just five to it did fix our problem and it is okay because our ship is really big. Just leave it with that. No, I want to bring back this start point. Let's just bring it down like this and Runo game. No, you can see it can hit us, right? It is tracing us, and that looks awesome. It can break us, right? 31. 30 Check can shoot: Now that we are aiming at ship. If it is insight, we want to check if we can shoot at it or not. So for doing that, let's just go to a vent graph in here. Then we have line trace, right? We want to break this out had result, right? And in here, we want to check. If it is hitting something's use a branch to check if it is hitting something. And if it hits something, we want to check if this head actor is equal to the target, right? So let's just put the target there. If the line trace hit the target, in that case, again, let's just use a branch, and in that case, the true will happen, and I want to create a variable, I don't want to call it can shoot, right? And we want to set this can shoot to true, right? But if it's not the target, we want to set this can shoot to false. Next thing, if it didn't hit anything, again, we want to set this can shoot to folds again. Now with this variable, what we want to do, we want to go at the begin play until it. Each five second, try to shoot at sheep, right? So for doing that, we can set a timer in here, set timer by event, right? And every five second, we want to check. If we are able to shoot at our ship, shoot at it, right? And we want this to be on loop, and we should create a custom event for the event that every 5 seconds happen, right? I want to call this one fire. And no first thing first in here, we want to check if we can shoot if it was true,'s check it with a branch. Every five second, we check. If we can shoot, let's just for no, use a printer string. And say can shoot. And if it's false, again, use another printer string and say cannot shoot, right? And I want to change the color of this one to red so you can see it better and collapse it after that. Now we have compile, save if you run over game, let's see what will happen. Right now, every 5 seconds, it should say can't shoot. You can see there is three of them, and it will say three time it can't shoot. But if you go forward, one of them will say can shoot. You can see can shoot. But two of them is not saying can shoot. If we go forward, you can see it says one other one should say can shoot as well. You can see can shoot. And if we go forward again, the third one will say can shoot. Let's just look at it, can see two of them should say can shoot. You can see it? No, we know when we can shoot at our ship. Now, let's see how we can actually fire our weapon, right? No, we don't need this printers ring anymore. 32. 31 Anti Ship projectile: Know that we know when we can shoot or fire or anti ship gun. We need a projectile to shoot it, right? So let's just go to contend what I want to do? I want to go to ship folder, go to blueprint and drag and drop this ship projectile and put it in blueprint folder over Anti ship and copy it there, right? Click on copy here. And now you can see it over here. We need to rename it to Anti ship Projectile. Anti ship projectile. No, let's just don't click on it to go inside it. You can see in here, we have apply radio damage. We don't need that. We can just use apply damage. So let's just delete this delete this as well. No, connect the execution pin for no to here. We don't need this draw debug sphere at all. We can just connect this to here directly, delete this as well. Now with that done, first thing that I want to do whenever it hit. The ship, we want to add some force to it because it is in water. When something hit it, it should move it a little bit. And how we can do that, first, we need to check if you are hitting the ship or not. So for doing that, we can get this head actor and cast it to BP ship, right? And it need execution pin. So let's just give it that. Let me bring this down like this. So it is more organized this way, right, like this. If it is ship, we want to add a force at location, right? Just choose one of them. All of them are the same. You can just delete this connected to it, right at force at location for over ship, but it needs a target, and it is a primitive component object reference. We can just connect the hit component, the component inside over ship that or projectile head, right? No it need a force. Now for the force, we can get this impact normal. Okay, and multiply it by a big value. So right clicking here, change it to float like -250,000, for example, right, and connect this to the force. And for the location, we can get the impact point location and connect it to it, right? After that, we can just connect these to this span system and all of that, right? Let's just head compiles save and know that or projectile is half ready, let's just use it. Go to BP Thip in here in case of true, we want to spawn actor from a class it is called projectile. It has projectile inside it, anti shape projectile. It needs to know where to spawn it, so we can get our skeletal mesh and get deep sock it transform because we need transform of the tip of over gun. So let's just go here. It's called Gun Joint socket, headf two to rename it Control C to copy the name and click in here, Control V to paste it over here. No, connect it over here. Compile, save. No, let's just say sat it. If you go forward, one problem that we can see in here, the initial speed of projectile is that much that it can't hit us. You can see it will go under the water. That is a problem. We can increase that. Let's just go to projectile movement and change the initial set to 50,000, right? That's more than enough. Let's just it compile, safe and go to our level and run our game again. Let's just see what will happen, right? No, you can see when it hit us, it did move the ship. Just look at it one more time. You can see whenever it hit us, it will move over ship. That looks awesome. That looks beautiful. Let's just go forward to see if it's working this way, as well. Yeah. Whenever it hit us, there will be a force added to our ship. 33. 32 Anti ship Projectile force and damage: No next thing that you want to do. We want to make the tissue projectile a little bit better. So for example, in here, let's just make some space. I want to bring all of these to the right a little bit. In here, first thing, first, I want to apply damage first, apply damage. It shouldn't be radial damage. We can just use apply damage. The damage actor is the head actor. We can just connect it there. It is more optimized to do it this way. And the base damage let's just use 25 for no and no, let's just test if you had compile save, go to ship, go to ship event graph down. Let's just find a space in here, and I want to create a event, any damage, right? And in here, I want to just show that printer string, right, show the damage to see if it is damaging us or not. Compile, save, go to or level, and Runo game. If we go forward, let's just look at it. It's hating us, and it says 25. So it correctly apply some damage to us. No, our projectile is finished, and it can apply damage as well. 34. 33 Anti ship VFX: Next thing that we want to do, we want to add some visual effects to our anti ship gun. So let's just go there. Whenever we fire our anti ship gun, what do you want to do? We want to add some visual effects. And this time, how I want to do it, I want to click in here and add particle system, right? First one, I want to do the muzzle flash. The Niagara system that I want to put there is called NS East RT firing. But you can see the position of it is not good. So because it is child or a skeletal mesh, we can just choose a parent socket. So clicking here. We want to put it at tip of our gun, so gun joint socket is more than enough. That's it. That's what we want it to happen. Again, for CT better, we can change the auto active so you can see it better. That looks awesome. The next effect that you want to add let's just add it, add the Nagar effect. And this one, I want to call it shell ejection, right? And for this one, let's just click in here and choose NS east RT shell eject, right? Again, the position of it is not good. So let's just change the parent socket to this time, I want to choose gun joint itself. So let's just go down until we find the gun joint or we can just search for it. Gun joint. You can see this up. We can change its position until it reached the position that we want it to be right? I think in here, it is good, right. That's it. If you want to check it, I will click on auto active. No, you can see it better, right? That looks awesome. So by default, we want it to be not activate, so select both of them and change the autoactive to false so it won't be happening. Now, in event, grab, whenever we spawn a projectile, we want to get these two, drag and drop both of these, and set active on it, right? Connect the execution pin. For both of them, we want to do it at same time. So new active to active. No, let's just test that out, compile, save. No, I want to runway game. Let's just go forward. And in here, I want to hit F eight, so I can see it there. Let's just go to it. No, you can see both of the visual effects is working fine. Look at it. I know you can see both of the Nagra effect is working fine. But one problem that you can see in here, the shell eject is happening twice. So let's just go to anti ship, and in here, click on Shell Eject, you can see the rate of fire. We need to change that to, for example, 5 seconds. Now after changing this rate of fire to five, we need to change the reset of the set active to through as well. So whenever we are firing anti ship gun, we are resetting it and activate it again. Let's just head compile, save, and let's just test that out. If we run or let's just go forward a little bit like this and hit the fate to see if it's working fine now or not. If we go close in here, you can see, both of them are working fine. The shell eject is happening at the right time, and the firing is happening as well. That looks awesome. The next thing that we want to do, we want to have a recoil effect. So whenever this is firing, it go back a little bit and forward. Let's see how we can do that next 35. 34 anti ship recoil: Next thing that you want to do, we want to have a recoil effect. And for doing that, let's just see in our skeleton what we want to change. If you click on gun joint, we want to change the position of this gun backward and forward, right? We want to do this. So the gun joint is the one that we want, right? Go to ABP, tissue and in here, make some space like this. We need to use this modified bone again. So search for modified bone. This time, we want to just change the translation. So we don't need this rotation. We don't need this scale as well. We need to just change the translation. So in translation, change this to add to existence at translation space. I want to change it to bone space, right? No, we need to choose the bone to modify. It is gun joint. So let's just put the gun joint there. And after that, let's just right click in here, split the stroking. We need to just change the translation because you can see it over here, the, right? Now, we can just promote that to a variable. So right click promote to a variable and I want to call it thecil value. For testing it let's compile. Now in here, you can see I can bring it back and forward, back and forward. That's what we want it to happen so it looks more natural. Now, let's see how we can calculate this recoil value. For doing that, I want to go to BP Aunt ship. Whenever we fire the untie ship, right? At the end of this, we want to create a timeline. So search for timeline, add the timeline, and I want to call it recoil. And every time we want to play from start, right? So hold control, disconnect from this one and connect it to this one, don't click on it to open it. I want the length to be 0.3, and I want to add a flow track. And I want to call it recoil value, right? And in here, I want to add some keyframe. So right click in here, add the keyframe at time zero, we want it to be zero. And again, right click in here, add another keyframe at time 0.1, we wanted to go to one and right click again, add another keyframe. At time 0.3, we want to go back to zero. That's it. We can just click in here and here to maximize this. We can select everything, right click on one of them, and change it to auto. So it has a curve, right? Just with that, if you go to event graph, we have the recoil value on output of this timeline. We can just promote it to variable and connect the update to it. That's it. Let's just hit compile, save. Now, let's just get that in our animation blueprint. For doing that, let's just go to event graph. We have the untie ship in here so we can get the recoil value from it, get the recoil value from it, and set the recoil value that we have in our animation Blueprint with this value that we get from our BP Anti ship. It need the execution pin, so let's just give it that. No with that, go to an graph because this recoil value right now is the value 0-1. That's why we need to multiply it by some value. For example, -50 because we wanted to go backwards, right? Just with that, let's just test it. Head compile, save, go to level, run over game, go forward a little bit, head of eight. No, let's just go to unt ship. You can see, no, it's working fine, and it looks beautiful. Just look at it how beautiful it sounds, right? It looks beautiful. No, we have a recoil effect as well. But the next thing that I want to do, I want to add some sound as well. Right now, it doesn't have any sound. So in here, I want to span, sound, add location as well. The sound that you want to spawn is called cannon fire, and the location of it, we can get actor location, that's more than enough, but we don't want to hear it from far away. That's why I want to use one of the sound attenuation that we create from before, like explosion, right? That's more than enough. Now, we have a sound. Let's just check that out. If you go to our level and run over a game, let's just go to it. You can see when it hit us, we can hear it. But if we get close to it, we should be able to hear it actually if it is firing, right? Of course, we didn't need this sound. But it's good to have it. Let's go backward. No, if you go here, you can see, we can hear it. But if we go backward, let's just look at it. We can hit a fade to go there and look at it. If we hit a fade, there will be sound. In here. Let's see if it should. We can see, you can hear it. If we get close, the volume will be more. Just look at it. And if we go backward, you can see, we won't be able to hear it a lot. And that sounds really good. 36. 35 Apply damage to antiship: Know what we want to do? We want to be able to destroy these anti ship guns. Let's see how we can do that. For doing that, let's go to BP Anti ship. And in here, we want to create an event for event, radio damage, right? And I want to just show it with a printer string. We want to destroy it whenever it gets damaged, so destroy it. Anti ship. I want to make a thread so you can see it better, right? Now, with that done, let's just test it to see if this event radial damage is happening or not. If we run or game and just zoom a little bit, you can see one problem that we have, we can shoot down. So that's why we need to modify our BP ship a little bit, right? Wherever we have the clamp for org to go down, so click on the ship open up the animation blueprint of it. And if you remember, we had a clamp in here, I want to change it to minus ten. And because over system, no, it's better, you won't be able to shoot at over ship. No, you can see we can shoot at it, and it's not hitting the ship at all. No, let's see if we can destroy it. Just barely hit it, right? No, it won't say destroyed. I don't know if I hit it correctly or not. But you can see it's not happening. Let me get close to it to see if it actually if we actually hit in it. I want to get really close to it to make sure that it's not working? Because it's not working right now. If we shoot it no, let's see. We can see we are hitting it, but it's not saying that the destroyed anti shape. What is the problem? The problem is that this skeletal mesh collision is not set up. Let's just go down. You can see it says no collision. We need to change that to custom. We can tell it to ignore everything. The important thing is to make the collision enable to query and physics and change the object type toward dynamic. The radial damage won't work with the static. After this, we need to enable generate overlap events. So check that. No, with that do, let's just head compile, save. If you go to our level, you can see, I did change the position of where players start so we will spawn closer to these anti ship guns so we can hit them. Now, if you run word game, you can see if I head close to it, it will say destroy anti ship. You can see. Again, if I head close to it, it's not close, you can see, it says destroyed anti ship again. Let's just hit the at deposits or radio damage. And again, you can see, no, it's easier to hit it. No, that's it. We are destroying the anti ship, but there is no visual effects for showing that. Next video, we will add that. We will add a blueprint for damaged anti 37. 36 Destroy antiShip: No whenever we shoot or anti ship, it should be destroyed, and we need to create a destroyed actor. So in here, I want to go to Blueprint folder or anti ship, right click in here, create blueprint class of type of actor, and we want to call it BP anti ship. Damaged. Okay? Don't click on it to open it. In here, I want to add estatic mesh, right, and change it to default syn root, replace it with default sin root by dragging and dropping it. Now, the estatic mesh that you want to add, it's called SM east RT, MM damaged. You can see it. It's exactly that, but it has different material, right? No, I want to add a Nagaral effect as well. So add the Niagara effect for us to show that it is destroyed. So click in here, it's called NS East art damage, right? Put it there. We can position it in here like this. No, it looks much better. No, whenever we shoot at our anti ship, instead of saying anti shape destroyed, we want to spawn this. So let's just go to anti ship instead of this, what we want to do? You want to spawn actor from a class damage. It has damage inside it, until ship damaged, right? The span transform, we can get the actor transformed. That's it. And after that, we can spawn system there as well, spawn system at location, explosion, right? Dust explosion. We can get the location of where get actor location, right, the location of this actor and that's it. And after that, we can destroy this untiship as well, right? Destroy it at the end, no let's say that no let's just shoot at it. And now you can see it will be destroyed and you can see it destroy this one. And now you can see this one is destroyed as well. Who is go back and shoot at this one as well. And now you can see it's dying. It's working. We destroyed three of them, and I think the visual effect is working fine, and it's beautiful. 38. 37 Ship destroyed: No next thing that we want to do. We want our ship to have health, so we can destroy it as well. So for doing that, I want to go to our BP ship. In here for the health, I want to create a variable. I will call it health. And the type of it, I want it to be float. Let's just create another variable. This one, I want to call it Max Health, right? The Max health, let's just had compile. I want to put it on, for example, 200 and the health, I want to put it on 50 right for no. Just with that, whenever our ship gets some damage, this event damage will happen. So what I want to do, I want to get the health subtracted with this damage, right, with this damage, and set the health with it, right? Like that and connect the execution paint here. And after that, we want to check if the health is less than zero, so we can check it with the branch. We get the health and less or equal to zero, right? In this case, we can use a printers ring to say the ship is destroyed. So let's just say sp is destroyed, right? With that, let's just to compile save. And next thing that I want to do in here, I want to add another print ring. So with that, we show the health as well. So in here, printestring, and show the health, just like that. Now, if you head compile every time it will apply damage 25, right? So if you run a game and three of them will shoot at us. It will be destroyed. You can see. But I want to change the position of our ship. After that, I should go backwards, so it won't be able to shoot at us. You can see it hit 25. Now, we have just 25. It will hit us one more time. It will be zero, and it will say, ship is destroyed. Let me test something. The shelf, I want to put it on, for example, 70, right? Head compile and no let's just test that out. We run our game, go backward. First time that it is hitting us, it will be 45. After that, when it hit us, just look at it when it hit us. It will be 20 and after that, when it hit us, again, the ship will be destroyed. You see? Everything cool. No whenever the ship is destroyed, instead of just saying ship is destroyed, we want to have some visual effects. So for doing that, I want to go to content drawer, go to Blueprint and here right click, create a blueprint class of type of actor, and I want to call it BP ship damaged. Okay. I'll click on it to open it in here. I want to add tatic mesh, just like that. I want to replace the default sn root with it. Now, the static mesh that I want to use is called. There is a damage inside it. So search for damage SM st ship damage. Put it there and you can see it over here. No, I want to add a Niagara effect to it as well. And it's called NS West damage, let's just put it there. We can add multiple of them. For example, this one, I want to put it over here. Duplicate it, control this duplicate it and put it over here, one more of them. Again, duplicate it one more time and put this one over here maybe. And now you can see how it looks like. I think it looks beautiful when we destroy it, right? Head compiled, save. No next thing, we want to go to a static mesh, and in here, we want to simulate physics. So when it spawn, it will sink right? Now, let's see what'll happen. If we compile save, go to our BP ship. Whenever the health get less than zero, this true will happen, and we want to spawn the destroyed ship, right? So click in here, search for damaged. It's called Ship damaged. It needs a transform. We can just get the actor transform. That's it. And everything I think is good. But after doing this, we want to destroy the ship, actually. So destroy actor that's a heat compiles, Save go to a level. Let's just look at it. It hitting us. Two of them will hit us. You can see. And that looks good. Two, next time we will be destroyed. Let's just say. And now you can see, we are destroyed. Again, let's just say that one more time. I want to go forward to looks more beautiful in here. Now, you can see if they hit us one more time, let's see what will happen, and that's it. We ship is destroyed. Now, next thing that you want to do in this ship damaged in event graph, we want to set a timer on its begin play. So set timer by event, right? After, for example, three second, we want to reopen the over level. So in here, let's just create custom event reload level. I will name it reload level. You can name it whatever you want. And in here, I want to say open level by name. I want to reopen this level. So let's just put the name there. New map. No, let's just test that one more time, compile, save. G here. If they destroyed us, let's see what will happen. Let's go closer, so they will destroy us much faster. That's it. If they hit us one more time, and it will be destroyed after 3 seconds, we will be restarted. You can see, No, our game is working fine, but we need to show the health actually for the player. Let's see how we can do that. Next. 39. 38 Health UI: Now let's see how we can create a health UI for our ship. For doing that, I want to go to content Derre, go to Ship folder in here, go to Widget, go to user interface in here and create user blueprint of type of user Widget. I want to call it DUBP ship UI, right? D click on it to open it. And in here, first and first, I want to go to panel, add a Canvas panel to our hierarchy, and after that, I want to add a progress board to it for our health boar. I want to call it health bar, right? And I want it to be a variable as well. Next, I want to anchor it to the left corner like this. I want to add a little bit offset to the left, so add 50 to position X, right? The size X, I want it to be 20, the offset to top, I want it to be 100, right? And offset to bottom, I want it to be 100 as well. Now you can see this is our health bar. And now if you change this percent 0-1, you can see what will happen if I change that like this, it will go from left to right. Let me zoom in here so you can see it better. You can see it will go from left to right. But the bar field type I want it to be from bottom to top, right. Now you can see it will fill up this way. At default we want it to be one for no, of course, next, I want to change the color to green. So put red and blue to zero, but the green to one. This is our health bar. We can decrease the alpha of it a little bit like this. We can make it more dark like this. I think that looks much better. This is our health. And for updating that, I want to go to graph, and in here, I want to create a function for updating the health. So I will call it update health. I want to get the health bar, progress bar, and set a percent on it, set percent. As you know, this percent is value 0-1, and we want to update it from outside of this WBPCPI so we can dry and drop this as input, right? We can just call it in percent. We click in here. You can see automatically it put it here, a type of float, right? Now that we have our health Bar what I want to do I want to go to over ship. And at the begin play, let me find the begin play. It should be up here. We want to create over widget. So create widget, right? And what widget we want to create it's called WBP Ship UI. And after that, we want to promote it to a variable. I want to call it ship UI as well, right. And after that, we want to add these two viewport, so add to viewport. That's it. We don't need this PUI to be here. So it will be there. If you head compile, save and go to our level and run, you can see the health bar will be there, but we are not updating it. First, let's see how we can update our health boar. We can get our ShipUI in here, get it, and update the health on it. There is a function inside that update health that we created together. No, we have the health right? And we have the max health. If you divide this health, by max health, it will give us a value 0-1. So for example, if the maxelf is 100 and the health is zero, the percent will be zero. It's okay. If the health is 50 and the max self is 100, it will give us 0.5. The percent will be okay as well. But if the health is 100 and max health is 100, it will give us 1%, and again, it will be okay. Now with that, if you run a game, you can see the health is updating successfully. No next thing that I want to do every time that we decrease the health, we want to update the health bar, right? So how we can do it, we can just copy all of this code for updating the health, control C to copy it and go down whenever we decrease the health that we done it over here, we can show it, right? Let me make some space, and we don't need this printesting, so let's just delete that. Control V to paste all of those code. And with that, we are updating the health whenever the health is decreased on event any damage, right? If you had compiled, save and go here and run over game, if they shoot at us, let's see what will happen. They did shoot at us. Now the health is decreased, and if they shoot at us one more time, you can see the health will be zero and the ship will be destroyed. That is working fine. Let's just and I think I killed two of them, right? No, we need to clean up a little bit. In anti ship, we have a box line trace that the debug of it is on. So let's just make it non. No next thing in projectile for overship. Let me find it. If you go to Ship Blueprint. Both of these projectile have a draw debug sphere. We don't need it anymore. We can just bypass it just like this for the other one as well. Just bypass this draw debug. We don't need the debug for over game, it's just for testing, right? No, let's just run over game. You can see we can't see if they can see us or not, but we can destroy them, and we are destroying them. 40. 39 Fix bug Radial damage is not working: No, there is a problem. Let me show it to you. If you go to our level and in here run over game, let's just go back so they can destroy us. If we zoom in here and shoot, for example, here, it should destroy the anti ship, right? Because we are heading close to it, but it's not destroying it unless we shoot exactly there. You see? It didn't destroy again. Let's just shoot it exactly on its place. Go up a little bit like this. And again, it's not destroyed. Again not destroyed. It's like we can't destroy it at all. It's like it's not happening at all. What is the problem? This is like a bugging Aerial engine, but we will fix it. So in here in the projectile that we use whenever we had something, we did use impact point, right? But if you change this impact point to impact location, if you use this location there, this will fix our problem. You know, Runo game, and if we head close to them, it will get destroyed, you see? Now, in here, if you head close to it, for example, at back of it, just go up here. You can see it did destroy it. So that was the first problem, the big that we fixed together. If you find any more big, you can just leave it in question section or in this coord channel, I will create a video for.
