pjhent_setmaxspeed didn't do anything. It still rotates around. When a ball hits the ball luncher, it gets bumped around to the wrong angle, and then goes all to hell bouncing and twirling all over the place.

To tell the truth, I don't understand about things like velocities and torque, so I probably have a few other settings off:

Code:

---

function init_ball_launcher()

{



	var constraint1[3];



	phent_settype(my, ph_rigid, ph_box);

	constraint1=phcon_add(ph_slider, my, 0);

	phent_setmaxspeed(my,10000,null); //this doesn't stop rotation (I tried with other values too)

	

	phcon_setparams1(constraint1, vector(1,0,0),nullvector,nullvector); //limit movement to the x axis

	phcon_setparams2(constraint1, vector(-50,0,0),nullvector,nullvector); //can't (shouldn't be able) to move more than 50 quants

	

	while(my!=null)

	{

	

		temp.x=-spring;//The amount of force to move the ball launcher

		temp.y=-1600000;//maximum force for the ball launcher

		temp.z=0			

		//punch ball out chute	

		//should make it so that it moves back and forth in 1 second intervals

                //seems to work okay until the ball launcher hits a ball and rotates around

		phcon_setmotor(constraint1, temp, nullvector, nullvector);

		sleep(0.5);

		temp.y-=temp.x;

		phcon_setmotor(constraint1, temp, nullvector, nullvector);

		sleep(0.5);

	}

}
