Let's write some code to add objects to spatial hashes! There's a lot more involved here than there was to adding objects to trees, but it'll be worth it when we're finished, I promise.

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:

Each week is its own release tag:
