Game Maker doesn't provide any built in 3D collision checking, but however if you are clever or a fluent programmer with 3D-skills you can write your own functions.
Games and Game Engines for Game Maker with real 3D collision checking[]
There are plenty of games that have semi 3D collision checking but only a few ones does real 3D collision checking math. Here follow a very few examples:
Different kinds of collision checking[]
There are some different kinds of collision checking in 3D:
- bounding box collision checking
- sphere collision checking
- cylinder collision checking
- intersecting line collision checking
- pseudo 3d collision checking:'''pseudo'''/'''semi''' 3d collision checking
