New AS3 2D Physics Engine Box2DFlashAS3 Based on Box2D for C++
Another great new 2D physics engine for AS3 has been released called Box2dFlashAS3 that is based on the excellent kit Box2D for C++. It has been a busy year for physics engines in AS3. FOAM was released this month, APE, the highly anticipated Motor Physics from polygonal labs and plenty more still I am sure.
The Box2dFlashAS3 version has some great demos available on the site that show, use the arrow keys to move to the different demos highlighted here.
- bridge
- ragdolls
- compound shapes
- rube goldberg / domino / tank tracks etc
- stacked boxes
- slider crank / piston
- pulleys
- gears
Box2DFlashAS3 is an open source port of Erin Catto’s powerful c++ physics library Box2D. Cycle through the demos to see some of the features.
Full source code for the engine and examples can be downloaded from the project’s sourceforge page found Here.
This kit is nice because it mimics Box2D for the crossover and ability of developers to use it in C++ and Flash AS3 moreso than other kits. It looks good and performs well except for a memory or FPS pause I get intermittently. The demos are already inspiring many uses of the features highlighted for games and effects.
