Description

This is a simple demo on how to do side-based rectangle collision response. It's extremely simple, and not very hard to understand.

Concept

I'm putting this here since it's not in the download. Basically how it works is when you move a rect, you first move along the X axis, test for a collision, move out, then move along the Y axis, test for a collision, and move out. This prevents the infamous "corner-catching" bug, and lets you move smoothly along walls.

flimm, the response is the actual stopping of the object. If you want you can extend it yourself to include bouncing :P soggywaffles: same here! Now I can continue my game project!

It's got collision detection, but not response (bouncing off the walls and spinning).
