ContactCallbacks class mixin
Used to listen to a BodyComponent's contact events.
Contact events occur whenever two Fixture meet each other.
To react to contacts you should assign ContactCallbacks to a Body's
userData or/and to a Fixture's userData.
If the Body userData is set to a ContactCallbacks the contact events
of this will be called when any Body's fixture contacts another Fixture.
If instead you wish to be more specific and only trigger contact events
when a specific Body's fixture contacts another Fixture, you can
set the fixture userData to a ContactCallbacks.
If the colliding Fixture userData and Body userData are null, then
the contact events are not called.
The described behavior is a simple out of the box solution to propagate contact events. If you wish to implement your own logic you can subclass ContactListener and provide it to your Forge2DGame.
