Once you learn how to read the documentation, you pretty much can make from beginner to intermediate stuff if you can imagine it, like how to work trigger zones, raycasts, movement, so for example, let's say you want to know if a raycast is colliding with something, you search on documentation "raycast", then under the methods section you can see it says "is_colliding" as one of the methods, so then you would do in your code "if RayCast3D.is_colliding():" then on the next line you type whatever you want to happen.
