The Fisix Engine is a 2D verlet physics engine for Flash. It is written completely in AS3 in order to make use of flash player 9’s improved cpu capabilities. Although Flash is still slower than platforms such as c/c++, or java, which means that you most likely won’t be able to make the next Half-Life in flash, it doesn’t mean you can’t do really cool stuff with 2D particles, constraints, rigid bodies, etc. and make great looking games and simulations.
