World Construction Kit (WCK) is a component framework for the Box2D Flash Alchemy Port, which allows 2D physics simulations for games / websites to be authored entirely within the Flash IDE.

As WCK Components (Worlds, BodyShapes and Joints) are added to the stage, either via code or the timeline, they automatically create the corresponding Box2d physics object. When removed from the stage, the Box2D object is destroyed. Transformations (rotation, scale and skew), and deeply nested instances in the display hierarchy, all translate correctly into the physics simulation.
