Bit by bit I came further. My model rotates quite good now. But don't stop. How can I stop it?

Code:

---

action gondel01 {
	my.passable = on;
	
	//Physics on
	phent_settype(my,PH_RIGID,PH_BOX);
	//Set a weight
	phent_setmass(my,23,PH_BOX);
	//Set a friction
	phent_setfriction(my,25);
	//Set an elasticity
	phent_setelasticity(my,50,5);
	//Set a damping
	phent_setdamping(my,50,90);
	//Set a gravity
	ph_setgravity(earthGravity);
	
	while(my) {
		
		vec_for_vertex(temp,kruis1,881);
		phent_addtorquelocal(my,vector(0,0,kruis1.pan));
		
		my.x = temp.x;
		my.y = temp.y;
		my.z = temp.z;
		
		wait(1);
	}
	phent_addforcelocal(my,vector(kruis1.pan,0,0),nullvector);
}

As you can see I work with physics. So I hope you can help me out of it.
