/** To be able to add custom scene node animators to Irrlicht and to make it possible for the
|

|
|
scene manager to save and load those external animators, simply implement this
|
||
|
|
interface and register it in you scene manager via ISceneManager::registerSceneNodeAnimatorFactory.
|
||
|
|
Note: When implementing your own scene node factory, don't call ISceneNodeManager::grab() to
|
||
|
|
increase the reference counter of the scene node manager. This is not necessary because the
|
||
|
|
scene node manager will grab() the factory anyway, and otherwise cyclic references will
|
||
|
|
be created and the scene manager and all its nodes won't get deallocated.
