[ODE] Simple character control

[Colin Bonstead]

I'm trying to add movement control for my avatar.  Right now, it's just a 
sphere, and I'd like it to scoot around the environment (not roll, because I'd 
like the pivot to keep it's vertical orientation).  The velocity of the avatar 
is derived from animation data each frame.

>From reading the docs and looking through the archives, it seems like a motor 
joint is the way to go.  The only one I see is the the angular motor.  That 
seems like it could be handy for keeping the avatar upright (restrict motion 
in two of the axis), and turning (around the vertical axis).  But how can I do 
linear motion?  Unless I'm missing something, you could only do that with a 
motor if you were rolling the object.
