Interface ContactListener

public interface ContactListener

Notified when bodies in a PhysicsWorld start and stop touching. Register with PhysicsWorld#addContactListener(ContactListener).

Callbacks fire from inside PhysicsWorld#step(float) -- i.e. on the game loop thread -- so it is safe to read and update game state directly, but you must not create or destroy bodies during the callback (defer that until after step returns).
