[ODE] movement force conversion

[Jon Watte]

This gets into humanoid character control logic. Where would you stop 
applying your muscle force, or apply less muscle force, if you were 
kicked? You'll have to figure out what you want the answer to be, and 
apply it to your model. It's likely your artists will have ideas about 
how this should be done, too, so coming up with a data-driven rule 
editor and preview tool would be ideal, if you're creating this for a 
game engine. If it's a home experiment, you can just wing it (but the 
data driven rules might still help).

Cheers,

The problem is more trivial :) : My model is strictly following
animations (with litle mistake) my intention is to simulate collision
of two walking or one kicking other walking models so that they will
stop follow strictly animation when collsion occur.

What I have now is working like that:

after adding external force into head only pelvis bone follows that
force (b/c its position isn't set by dJointSetAMotorAngle which sets
children pos. only). After collision situation is the same.

My plan is to propgate decreasing weight of animation through affected
by collision bones (bodies). But I'm asking whether it could be done
simpler.
