And I am back again with a new question. I am almost done. But the model that need to be rotating is like double. Here is a screenshot of the whole model.



You see that the model at the cross is double. But I don't no why.

Here is the code of the model.

 Code:
action gondel01 {
	gondel001 = my;
	my.passable = on;
	
	my.scale_x = 0.5;
	my.scale_y = 0.5;
	my.scale_z = 0.5;
	
	//Physics on
	phent_settype(my,PH_RIGID,PH_BOX);
	//Set a weight
	phent_setmass(my,23,PH_BOX);
	//Set a friction
	phent_setfriction(my,100);
	//Set a damping
	phent_setdamping(my,45,10);
	//Set a gravity
	ph_setgravity(earthGravity);
	
	gondel1 = phcon_add(PH_HINGE,my,kruis01);
	phcon_setparams1(gondel1,my.x,vector(0,0,1),nullvector);
	phcon_setparams2(gondel1,vector(-360,360,0),nullvector,nullvector);
	
	while(my) {		
		vec_for_vertex(temp,kruis01,875);
			phent_addvelcentral(my,vector(temp.x*time_step,temp.y*time_step,temp.z*time_step));
		
		my.x = temp.x;
		my.y = temp.y;
		my.z = temp.z;
		
		wait(1);
	}
}

In another code the entity is made 1 time.

Thanks in advance.
