b2PulleyJoint(native)

The pulley joint is connected to two bodies and two fixed ground points.

Methods

  • getGroundAnchorA() : Multivalue
    Get the first ground anchor.
  • getGroundAnchorB() : Multivalue
    Get the second ground anchor.
  • getLength1() : Float
    Get the current length of the segment attached to bodyA.
  • getLength2() : Float
    Get the current length of the segment attached to bodyB.
  • getRatio() : Float
    Get the pulley ratio.

Remarks

The pulley supports a ratio such that: length1 + ratio * length2 <= constant Yes, the force transmitted is scaled by the ratio. The pulley also enforces a maximum length limit on both sides. This is useful to prevent one side of the pulley hitting the top.
