Sphere Displacement and Collision Avoidance - 3D Collisions in GameMaker
15What if instead of moving a distance and checking for collision, you could instead implement a form of collision avoidance to figure out the nearest free space in the event of a collision? Let's talk about sphere displacement!
This video took about 50 years off my lifespan.
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:
