public Class ContactImpulse

Class Inheritance

extends Object

java.lang.Object
com.badlogic.gdx.physics.box2d.ContactImpulse

Contact impulses for reporting. Impulses are used instead of forces because sub-step forces may approach infinity for rigid body collisions. These match up one-to-one with the contact points in b2Manifold.
