  * @file collision.h
- *  Definition of a collision as a two WE hit each other
+ *  Definition of a collision relation of two WorldEntities
  *
- *  A is shared between two WorldEntity's CollisionHandles if both are subscribed to this event. In this case only one
+ *  Is shared between two WorldEntity's CollisionHandles if both are subscribed to this event. In this case only one
  *  of the two CollisionHandles will calculate the CollisionReaction and the bDispatched flag will be set afterwards
  *  to signal that it's already cared about and should be ignored.
+ *
+ *  The collisions itself are saved in this container (CollisionEvent). Since there can be multiple collision events
+ *  for one collision. Imagine: two objects are intersecting (this throws a Collision): many collision boxes will fire
+ *  each of this boxes will "create" a CollisionEvent.
