Defines a single collision event.
A specialized kind of CollisionHandler that throws an event for each collision detected.
virtual void begin_group()
Will be called by the CollisionTraverser before a new traversal is begun.
virtual void add_entry(CollisionEntry *entry)
Called between a begin_group() .
virtual bool end_group()
Called by the CollisionTraverser at the completion of all collision detections for this traversal.
A specialized kind of CollisionHandler that throws an event for each collision detected.
TypeHandle is the identifier used to differentiate C++ class types.
