## Member Function Documentation

virtual void Ogre::MovableObject::Listener::objectAttached | ( | MovableObject * |  | ) | `[virtual]`

MovableObject has been attached to a node.

Definition at line 72 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::Listener::objectDestroyed | ( | MovableObject * |  | ) | `[virtual]`

MovableObject is being destroyed.

Definition at line 70 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::Listener::objectDetached | ( | MovableObject * |  | ) | `[virtual]`

MovableObject has been detached from a node.

Definition at line 74 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::Listener::objectMoved | ( | MovableObject * |  | ) | `[virtual]`

MovableObject has been moved.

Definition at line 76 of file OgreMovableObject.h.

virtual const LightList* Ogre::MovableObject::Listener::objectQueryLights | ( | const MovableObject * |  | ) | `[virtual]`

Called when the movable object needs to query a light list.

Remarks:
  If you want to customize light finding for this object, you should override this method and hook into MovableObject via MovableObject::setListener. Be aware that the default method caches results within a frame to prevent unnecessary recalculation, so if you override this you should provide your own caching to maintain performance.

Note:
  If you use texture shadows, there is an additional restriction - since the lights which should have shadow textures rendered for them are determined based on the entire frustum, and not per-object, it is important that the lights returned at the start of this list (up to the number of shadow textures available) are the same lights that were used to generate the shadow textures, and they are in the same order (particularly for additive effects).
  This method will not be called for additive stencil shadows since the light list cannot be varied per object with this technique.

Returns:
  A pointer to a light list if you populated the light list yourself, or NULL to fall back on the default finding process.

virtual bool Ogre::MovableObject::Listener::objectRendering | ( | const MovableObject * | ,
|  | const Camera * |  |
| ) |  |  | `[virtual]`

Called when the movable object of the camera to be used for rendering.

Returns:
  true if allows queue for rendering, false otherwise.
