Hey Guys, Heres a ton of code. AABB math based Collision.

Its not working though, Its having tons of problems. I would really like to do it this way, as its so efficient and powerfully precise.

The issue is the same two problems keep coming up. Either Its solving the collision too quickly and the rabbit is being moved up before it even touches the tile again (usually involving for loops) or its like this, which looks good as theres no unnessary "bouncing" (the irony is the character is a rabbit), but the player often falls through tiles or isn't hitting the the wall at the same time as the floor, or is barely nipping into the floor and finding the corner of the side of it and treating it like a wall and not moving sideways on the ground.

Help?

Heres a megaswf link to it. http://megaswf.com/s/2439428
