Class Breakable

java.lang.Object

net.dermetfan.gdx.physics.box2d.Breakable

public class Breakable
extends java.lang.Object

Breaks bodies or fixtures if they get hit too hard. Put in fixture's or body's user data and set Breakable.Manager as ContactListener.
Don't forget to call Breakable.Manager.destroy() after every world time step.
You can manually destroy fixtures or bodies using the Breakable.Manager.destroy(Fixture) and Breakable.Manager.destroy(Body) methods.
