Revolute Joint Box2D Physics Animation: Add Bodies

Joints in the Box2D Actionscript Physics animation are used to constrain bodies to the world or to each other. We discuss how to create Revolute Joints in very details in this series of box2d physics simulation.

Please update flash player to view this Flash ActionScript tutorial!

Flash Box2D Physics Simulation Tutorial Content

A revolute joint in Box2D Physics simulation forces two bodies to share a common anchor point, often called a hinge point. To specify a revolute joint you need to provide two bodies and a single anchor point in world space. The initialization function assumes that the bodies are already in the correct position.

STEP 1: Add Bodies to Stage and Keep Static
Since the initialization function of Box2D assumes that the bodies are already in the correct position , the first step is to add bodies on the stage to make sure that they are in correct position. This is best to keep all bodies in static for easy position analysis.
