Changeset 2466 for code/branches/presentation/src/orxonox/objects/Scene.h

Message:

Added callback for collisions. Every WorldEntity that collides against another will be called with the following function:
virtual bool collidesAgainst(WorldEntity* otherObject, btManifoldPoint& contactPoint);
btManifoldPoint is from Bullet and tells you more about the contact point, like position.

Per default, the callback is disabled. Enable it with this→enableCollisionCallback(), for instance in your derived class constructor.
Note that if you activate the callback for e.g. SpaceShips, but not for MovableEntities, then collidesAgainst will only be called in the SpaceShip. This could be changed however, just ask me.
