Overview

Read-only value that, upon instantiation of a "pulley" joint, indicates the distance in pixels between the first anchor point and its stationary pulley anchor point.

Example

local pulleyJoint = physics.newJoint( "pulley", bodyA, bodyB, anchorA_x, anchorA_y, anchorB_x, anchorB_y, bodyA.x, bodyA.y, bodyB.x, bodyB.y, 1.0 )
