The Fisix engine is a verlet based physics engine for Flash written in Actionscript 3.0. This engine is aimed towards use in games and other relatively cpu intensive real-time applications as it makes 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.

Examples of the Fisix Engine in Use:

Mona the Ragdoll

Boxes Demo

Bike Game

Hourglass
