Collision detection engine

It is a really good system but I think if you used methods you could make sure it is working even faster. I wish however that I could use such a simple system for the skiing game I am making. My skiing game will need to figure out the side the collision ocured on then fall acording to the speed and direction. I like this though, but you should think about making this work wit iregular size objects
