Physaxe is a 2D Rigid Body Library written in haXe. It's been highly optimized for the Flash 9 Player, with the best optimizations available.
Physaxe is based on several existing physics engines, mainly :
Box2D, the reference open source physics engine Glaze, an AS3 engine which is a port of Chipmunk, itself based on Box2D
Physaxe features are :
rigid body consisting in several shapes shapes supported are circles, segments (with rounded edges) and arbitrary convex polygons customizable broadphase (currently bruteforce and y-sorted list are available) island resolution and sleeping (allow ~0 CPU to be spent when groups are sleeping) constraint solver based on Box2D sequential impulses customizable body properties, such as linear/angular friction and maximized motion
