Public Member Functions
void	Initialize (b2Body *bodyA, b2Body *bodyB, const b2Vec2 &groundAnchorA, const b2Vec2 &groundAnchorB, const b2Vec2 &anchorA, const b2Vec2 &anchorB, float ratio)
	Initialize the bodies, anchors, lengths, max lengths, and ratio using the world anchors.

Public Attributes
b2Vec2	groundAnchorA
	The first ground anchor in world coordinates. This point never moves.
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.
float	lengthA
	The a reference length for the segment attached to bodyA.
float	lengthB
	The a reference length for the segment attached to bodyB.
float	ratio
	The pulley ratio, used to simulate a block-and-tackle.
Public Attributes inherited from b2JointDef
b2JointType	type
	The joint type is set automatically for concrete joint types.
b2JointUserData	userData
	Use this to attach application specific data to your joints.
b2Body *	bodyA
	The first attached body.
b2Body *	bodyB
	The second attached body.
bool	collideConnected
	Set this flag to true if the attached bodies should collide.

Detailed Description

Pulley joint definition. This requires two ground anchors, two dynamic body anchor points, and a pulley ratio.
