class | CollisionTraverser |
The abstract interface to a number of classes that decide what to do when a collision is detected.
One of these must be assigned to the CollisionTraverser that is processing collisions in order to specify how to dispatch detected collisions.
Definition at line 33 of file collisionHandler.h.
|
virtual |
Called between a begin_group() .
. end_group() sequence for each collision that is detected.
Reimplemented in CollisionHandlerEvent, CollisionHandlerHighestEvent, CollisionHandlerPhysical, CollisionHandlerQueue, and CollisionHandlerFluidPusher.
Definition at line 48 of file collisionHandler.cxx.
References end_group().
Referenced by begin_group(), and CollisionEntry::has_contact_normal().
|
virtual |
Will be called by the CollisionTraverser before a new traversal is begun.
It instructs the handler to reset itself in preparation for a number of CollisionEntries to be sent.
Reimplemented in CollisionHandlerEvent, CollisionHandlerHighestEvent, CollisionHandlerPhysical, and CollisionHandlerQueue.
Definition at line 38 of file collisionHandler.cxx.
References add_entry().
|
virtual |
Called by the CollisionTraverser at the completion of all collision detections for this traversal.
It should do whatever finalization is required for the handler.
The return value is normally true, but if this returns value, the CollisionTraverser will remove the handler from its list, allowing the CollisionHandler itself to determine when it is no longer needed.
Reimplemented in CollisionHandlerEvent, CollisionHandlerHighestEvent, and CollisionHandlerPhysical.

Sets the root of the collision traversal.
Only set if wants_all_potential_collidees is true

Returns true if handler wants to know about all solids that are within the collider's bounding volume.
