Heya,

this question... well

Its simple:

I want an entity to turn towards a target

Code:

---

vec_set(temp,vecTarget.x);       
vec_sub(temp,my.x);      
vec_to_angle(my.pan,temp); 

---

In order to maintain the entity vertical i will use my.tilt = 0.

But i want to control the entity´s TILT like rotating and pointing always to the target, vg. my.tilt += 10 * time_step;

But this dont work, so i ask which will be the way to do that?

Thanks.
Cheers

Can you explain a little more on specifically what you want?
Do you mean like a gun turret tracking an aircraft?
Perhaps you need to set roll to 0, and let pan and tilt be
set by vec_to_angle.

Well,

imagine an entity always facing a target, but that entity needs to be always rotating around its y axis or changing its tilt angle..

Do you mean you want to control the tilt manually while the pan always looks at a target?
If so, here is a quick example using the mouse to manually control the tilt:
Code:

---

  

var tilt_ang;
 
while(me)
{ 
  vec_set(temp,vecTarget.x);
  vec_sub(temp,my.x);
  vec_to_angle(my.pan,temp); 
  
  my.tilt = 0;
  tilt_ang += (mouse_force.y * 3) * time_step;
  tilt_ang = clamp(tilt_ang, -80, 80); //clamp tilt between 80 and -80 degrees
  my.tilt += tilt_ang;
  
  wait(1);
}

---

You might also want to set the roll to 0 when you set the tilt to 0, or your "my" will roll.

Yeap, that´s it very simple, but my head its almost blowing up today..

Thanks Josiah,

Cheers

hehe, I know what you mean, happens to me quite often.

Good luck!
