Okay, let's call it a ball launcher then. That is a better word. Thanks for that tip, though I'm still having trouble with my ball launcher. It behaves very strangely indeed:

Code:

---

//Ball launcher



constaint1[3]=1,0,0; //only allows movement on x axis?



function create_ball_launcher()

{

	temp.x=ball_pos.x+400; //put in position relativeto where ball is created

	temp.y=ball_pos.y;

	temp.z=ball_pos.z-130;

	

	ent_create("ball_launcher.wmb", temp, init_ball_launcher);	

}



function init_ball_launcher()

{





	phent_settype(my, ph_rigid, ph_box);

	phcon_add(ph_slider, my, 0);

	

	phcon_setparams1(constraint1, vector(1,0,0),nullvector,nullvector); // I thought that the second agument of this set the contraint axis?

	phcon_setparams2(constraint1, vector(-50,0,0),nullvector,nullvector);

	

	while(my!=null)

	{

	

		temp.x=-spring + random(200)-100;

		temp.y=1600000;

		temp.z=0;			

		//punch ball out shoot			

		phcon_setmotor(constraint1, temp, nullvector, nullvector);

		sleep(0.5);

		temp.x-=temp.x;

		phcon_setmotor(constraint1, temp, nullvector, nullvector);

		sleep(0.5);

	}

}

The entity bobs around and spins.

Also, is there a way to stop the entity from spinning?
