If you’re into flash game development then chances are that you already came across few physics library for Actionscript. This post is about actionscript physics library Flade & APE.
Official quote for Flade:
Flade (Flash Dynamics Engine) is an open source Actionscript 2.0 library for simulating 2D physics using Verlet integration. It currently features rectangular, circular, & wheel primitives, spring & angular constraints, and surfaces composed of line segments, circles, & rectangles. It’s designed primarily for games with a goal of speed and ease of use, and is MTASC -strict compatible.
Flade isn’t complete game engine, but it is more of physics engine. It is open source and it is focused on Actionscript 2.0. It is now closed but if you’re still looking for old engine cause of your restriction of Actionscript 2.0. Then you can find flade here.
As Flade is closed, but new project called APE featuring support for Actionscript 3.0 is active now.
