[5039]2 * @file collision.h
[7959]3 *  Definition of a collision as a two WE hit each other
[8124]4 *
5 *  A is shared between two WorldEntity's CollisionHandles if both are subscribed to this event. In this case only one
6 *  of the two CollisionHandles will calculate the CollisionReaction and the bDispatched flag will be set afterwards
7 *  to signal that it's already cared about and should be ignored.
