Class JointBreaker

java.lang.Object
  org.jbox2d.p5.JointBreaker

All Implemented Interfaces:

org.jbox2d.dynamics.Steppable

public class JointBreaker
extends java.lang.Object
implements org.jbox2d.dynamics.Steppable

Tracks the reaction force of a given joint, and destroys the joint if the reaction force is above a given threshold AND is between the minimum and maximum allowable angles. This is useful for creating mouse-controlled joints where the "release" should only happen in one direction, and when a certain force threshold is reached.
