Question by theUndeadEmo · Aug 15, 2013 at 02:23 PM · rotation1 frame

Rotate Object in a single frame

How would i rotate an object to face another in a single frame

 Vector3 lookat = (Vector3 (100,1,100) - transform.position).normalized;
 
 transform.rotation = Quaternion.Slerp (transform.rotation, Quaternion.LookRotation (lookat), speed * Time.deltaTime);

the code above takes frames to complete, when i increase the speed it is off

More Info:

what i am doing is resetting the gameobjects rotation to face a target once it is respawned

ins$$anonymous$$d of setting the rotation manually, have you considered using transform.LookAt(object.transform)? Also, you could try transform.forward = mesh.bounds.center - object.gameObject.mesh.bounds.center

I edited my 1st post (Vector3 (100,1,100), ins$$anonymous$$d of target.position) as my target is a vector3 coordinate

also i tried using lookAt, it didnt work.

In that case, try doing a Quaternion.Euler ins$$anonymous$$d of a Slerp. Isn't one of the built in function of a Slerp the fact that it eases the rotation?

If you do transform.localRotation = Quaternion.Euler(Vector3(calculate this)); then it should rotate it in one frame.

Try this:

 Vector3 lookat = (Vector3 (100,1,100) - transform.position).normalized;
  
 transform.rotation = Quaternion.LookRotation (lookat);
