Being a big lover of the real time strategy and city builder genre and being a generalist programmer I thought heck why not. Let's learn some more about Unity through doing. This project took me probably about 2 days to setup and research. What started as a passion project has now turned into a course. Many people I showed asked me to please produce a course on how I achieved this. So parts of the course is now online I am still producing videos so if you are interested in the course and have watched the whole thing just check in every now and then to see the progress.

Let's talk about the thought process of the project. I wanted to make it 3D because general RTS games require Isometric tiles. Being a generalist programmer, my isometric drawing skills are somewhat sub par. So I figured I have put together some basic shapes in blender before and could easily put together some basic assets to setup a game scene with some buildings, trees, rocks and particle effects.

So I kicked off with the notion of an open world and to make things more interesting a randomly or procedural generated landscape. From my university days when I did computer graphics in good old opengl. I knew that my starting point would be to setup some vertices on a grid and fill those in with triangles. Then apply some algorithm to create peaks in the mesh. I came across a nice algorithm called perlin noise, which already was built into Unity and could produce peaks from applying a form of averaging using the surrounding vertices in my mesh.

From here I applied some basic texture to the terrain using all the unity built in features.

Giving me a nice little terrain. From here I did some modelling in blender.

Created a few little other assets like rocks and some basic space age buildings. I added some more procedural generation to add these assets to the game. To end up with this.

At this point I had to add some UI and do some movement scripting to allow me to scroll around the screen with the mouse. I built a basic economy around 3 main resources, electricity,water and money. With the way the scripts have been put together this is easily extensible so can add any number of resources.

Over all this was a nice little project to sink my teeth into. If you are curious about how I built this feel free to join my course and watch the lessons. If I get enough students I will upload more and more content.
