b2Vec2	groundAnchorB
	The second ground anchor in world coordinates. This point never moves.
b2Vec2	localAnchorA
	The local anchor point relative to bodyA's origin.
b2Vec2	localAnchorB
	The local anchor point relative to bodyB's origin.
float32	lengthA
	The a reference length for the segment attached to bodyA.
float32	maxLengthA
	The maximum length of the segment attached to bodyA.
float32	lengthB
	The a reference length for the segment attached to bodyB.
float32	maxLengthB
	The maximum length of the segment attached to bodyB.
float32	ratio
	The pulley ratio, used to simulate a block-and-tackle.

Detailed Description

Pulley joint definition. This requires two ground anchors, two dynamic body anchor points, max lengths for each side, and a pulley ratio.
