Hi,
I'm don't know anything much about physics. So you'll have to excuse my noobiness when it comes to physics

I've been adapting the code from 3PM Feb, and here's what I have:
Code:

---

  
//-----------------------------
//Variable Defines
//-----------------------------
//Temp physic variables
var h_id;
var p2[3];
var p3[3];
var p4[3];
var p5[3];
var p6[3];
var door_max[3];

//-----------------------------
//Pointer Defines
//-----------------------------
entity* hinge;						//Hinge pointer

//-----------------------------
//Actions
//-----------------------------
//---------------
//Desc: Hindge which connects the door
//---------------
action hinge_ent
{
	hinge = my;				//Give it the hinge pointer
	my.passable = on;		//Passable
	wait(1);
}

//---------------
//Desc: A standard door
//---------------
action door
{
	while(player == null)
	{
		wait(1);										//Prevents empty pointers
	}
	phent_settype(my, ph_rigid, ph_box);	//Is a physics object
	phent_setgroup(my, 2);
	phent_setmass(my, 100, ph_box);
	phent_setfriction(my, 10);
	phent_setelasticity(my, 2, 1);

	//Sets the parameter vectors
	vec_set(p2, vector(0, 0, 1));
	vec_set(p3, vector(0, 0, 0));
	vec_set(p4, vector(-90, 90, 0));
	vec_set(p6, vector(0, 0, 0));
	
	h_id = phcon_add(ph_hinge, my, hinge);		///Enables a 'hinge' joint
	
	//Set the parameters
	phcon_setparams1(h_id, hinge.x, p2, nullvector);
	phcon_setparams2(h_id, p4, nullvector, nullvector);
	
	//Set the speed
	vec_set(door_max, vector(20, 10, 0));
	phcon_setmotor(h_id, door_max, nullvector, nullvector);
}

---

Now, the problem is the door keeps going away from the hinge, which it shouldn't do. Have I missed something?
Here's a pic of it set up in WED incase there's a problem with that:


And here's the result:


Thanks for any help,
