"""

ObserverWalker.py is for avatars.
|
|
|
|
A walker control such as this one provides:
|
|
- creation of the collision nodes
|
|
- handling the keyboard and mouse input for avatar movement
|
|
- moving the avatar
|
|
|
|
it does not:
|
|
- play sounds
|
|
- play animations
|
|
|
|
although it does send messeges that allow a listener to play sounds or
|
|
animations based on walker events.
