Physics Engine

Does anybody know of any way I can implement a physics engine, in my app? Any commercial or free plugins or anything of a similar nature, preferably for the SuperSpriteSurface class? Thanks

What kind of features are you looking for in such a physics engine (e.g. collision detection, movement)?

Everything that you would expect in a 2D game engine and if possible 3D.

A lot of game engines use

This could be ported over since the source code is available.

Someones started on that but couldn’t quite get it right. It runs, and demo 4 is fun to watch, but things get too stuck or sometimes fly apart. Maybe it’s a good starting place.
