Collisions
I spent an unfortunate percentage of my life making videos about implementing a comprehensive 3D collision system in GameMaker from scratch.
Right, let's get into this.
In case you for some unfathomable reason don't want to go through and do all that by hand, you can also download the completed version of the project on Itch here or see the repository on Github here.
This requires a relatively recent version of GameMaker to use. I don't remember exactly what the most recent language feature in use here is but I'm going to wildly guess that you should be on 2023.6 just to be safe.
The system is (vaguely) modeled after the Bullet collision system. If you used that at any point in the past, this might look a bit like a simplified version of it.
