Source code for direct.controls.PhysicsWalker

"""
PhysicsWalker.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 messages that allow a listener to play sounds or
animations based on walker events.
