Hi Thomas! I am making a FPS game and I can't play the game because it is giving me a warning that says "Invalid get index 'transform' (on base: 'null instance'). here is the code. extends CharacterBody3D

@onready var MainCamera = get_node("%MainCamera")

const SPEED = 5.0
const JUMP_VELOCITY = 4.5

var CameraRotation = Vector2(0,0)
var MouseSensisitivy = 0.001

# Get the gravity from the project settings to be synced with RigidBody nodes.
var gravity = ProjectSettings.get_setting("physics/3d/default_gravity")

func _ready():
Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

func _input(event):
if event.is_action_pressed("ui_cancel"):
Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE)

if event is InputEventMouseMotion:
var MouseEvent = event.relative *MouseSensisitivy
print(event.relative)
CameraLook(MouseEvent)

func CameraLook(Movement: Vector2):
CameraRotation += Movement
CameraRotation.y = clamp(CameraRotation.y,-1.5,1.2)

transform.basis = Basis()
MainCamera.transform.basis = Basis()

rotate_object_local(Vector3(0,1,0), -CameraRotation.x) # first rotate y
MainCamera.rotate_object_local(Vector3(1,0,0), -CameraRotation.y) #then rotate x

func _physics_process(delta):
# Add the gravity.
if not is_on_floor():
velocity.y -= gravity * delta

# Handle Jump.
if Input.is_action_just_pressed("ui_accept") and is_on_floor():
velocity.y = JUMP_VELOCITY

# Get the input direction and handle the movement/deceleration.
# As good practice, you should replace UI actions with custom gameplay actions.
var input_dir = Input.get_vector("ui_left", "ui_right", "ui_up", "ui_down")
var direction = (transform.basis * Vector3(input_dir.x, 0, input_dir.y)).normalized()
if direction:
velocity.x = direction.x * SPEED
velocity.z = direction.z * SPEED
else:
velocity.x = move_toward(velocity.x, 0, SPEED)
velocity.z = move_toward(velocity.z, 0, SPEED)

move_and_slide

By the way i am working in Godot 4.0.1.
Thank You
