What is the best function for moving eg. People in Bullet Engine? applyImpulse, setForce etc. ?

I don't know how Bullet works, but this might help you.
this is the essence of this post on the newton forum:

force = ( desiredVelocity - currentVelocity ) * mass 
addForce ( force / updateStepSpeed )

Yes this is good function for moving in Newton, but in Bullet We can't use it.

Yes you can. Bullet has an "applyForce" function.

Is fact, but how can I good calculate 2 params for applyForce eg. first: force is good, bacause this is vector my moving, but rel_pos? if i have good moveing vector and rel_pos(0,0,0) my node isn't move:/

Hey I recommend to use the framework from the Irrlicht Bullet Demo, it is very well made. (Also remember to apply the fix by omaremad at the end, and if you are using msvc there are some small errors to fix as they pop up for the iterators and things (There is also a triangle mesh cast or something).)

Here it is: http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=17910
