The only collision hierarchy I've used so far for this has been the Octree, which works pretty well most of the time. But there are others you can use as well. Let's talk about one that's often seen in 2D games, the Quadtree!

3D collisions in native GML are one of the more commonly requested tutorial subjects I get. This is a big subject and will require a long time to cover properly, but they can be done - no external DLLs required!

As always, you can find the GML code on my tutorial Github:
