Inheritance diagram for b2PulleyJointDef:

## Public Member Functions
void | Initialize (b2Body *bodyA, b2Body *bodyB, const b2Vec2 &groundAnchorA, const b2Vec2 &groundAnchorB, const b2Vec2 &anchorA, const b2Vec2 &anchorB, float32 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.
float32 | lengthA
| The a reference length for the segment attached to bodyA.
float32 | lengthB
| The a reference length for the segment attached to bodyB.
float32 | ratio
| The pulley ratio, used to simulate a block-and-tackle.
Public Attributes inherited from b2JointDef

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.
