/** This scene node animator can be attached to any scene node modifying it in that

|
way, that it cannot move through walls of the world, is influenced by gravity and
|
|
acceleration. This animator is useful for example for first person shooter
|
|
games. Attach it for example to a first person shooter camera, and the camera will
|
|
behave as the player control in a first person shooter game: The camera stops and
|
|
slides at walls, walks up stairs, falls down if there is no floor under it, and so on.
