I’ve recently discovered that APE (Actionscript Physics Engine) lacks a lot of basic features that I really wanted to use in the game I was going to make with this, which is a shame as it was so easy to program. The biggest problem I found with the engine was the lack of any rectangle physics, so I stuck it out and attempted to learn Box2DFlashAS3 which I found needlessly complex and required to many lines to get the desired effects (in other words I’m too lazy!).

So instead I found a substitute called QuickBox2D which is a library built on top of Box2DFlashAS3 which makes everything a lot easier as well as adds a couple more helpful features. But on top of that the creators website has LOADS!!! of examples of the engine working which makes it so easy to learn from references.

So check it out if you are looking to learn an AS3 Physic Engine as it is definitely the easiest to pick up and play with. Also here are two examples to compare APE and QB2D.
