I finally got it working!

xXxGuitar, your code was absolutely correct.
However, vec_rotate doesn't seem to work as expected in this particular case.

As far as I know, the order in which the Euler angles are changed is important.
Obviously, rotating the direction vector by each Euler angle seperatly solves the problem:
Code:

---

vec_rotate(vec_to_ent, vector(temp.pan,0,0));
vec_rotate(vec_to_ent, vector(0,temp.tilt,0));
vec_rotate(vec_to_ent, vector(0,0,temp.roll));

Thank you all for your help!

Great to see you got it working
But could you post the entire code up again, just for convenience

Thanks in progress

Of course; here is the working code:

Code:

---

define barrel_handle, skill1;

action ent_turret
{
	my.barrel_handle = handle(ent_create("turret_barrel.mdl", my.x, NULL));
	
	while(my) {
		
		you = ptr_for_handle(my.barrel_handle);
		
		var  vec_to_ent[3];
		var  ang_to_ent[3];

                vec_diff(vec_to_ent, camera.x, my.x); // direction vector
		
                // transform the direction vector into local space via rotating it
                // by the turrets inverted angles
		vec_rotate(vec_to_ent, vector(-my.pan,0,0));  
		vec_rotate(vec_to_ent, vector(0,-my.tilt,0)); 
		vec_rotate(vec_to_ent, vector(0,0,-my.roll));
      
		vec_to_angle(ang_to_ent, vec_to_ent); // angle of direction vector

		// first rotate the turret's body
		ang_rotate(my.pan, vector(ang_to_ent.pan,0,0));
		
                // now rotate the barrel
		vec_set(you.pan, my.pan);
		ang_rotate(you.pan, vector(0,ang_to_ent.tilt,0));
		
		
		
		wait(1);	
	}	
}

Oke thanks

Wow, I never thought about changing the order. I'm impressed, congratulations...


Cool. tested and confirmed. I have it working with a little Turret as well, but only using bones instead of multi-ents...
