Box2D. Box2dPulleyJoint

Box2D Pulley Joint

Connects to two objects and two fixed ground points
The pulley supports a ratio such that: length1 + ratio * length2 <= constant
The force transmitted is scaled by the ratio

Constructor

new Box2dPulleyJoint(objectA, objectB, groundAnchorA, groundAnchorB, anchorA, anchorB, ratioopt, collideopt)

Create a pulley joint
