LookAt but without z axis?


I want use a tranform.lookat function for look an object but with a different z rotation?

Plz Thank you Sry for my bad english

There's no version of LookAt which operates on a different axis.

To get around this, you can either:

a) rotate the object after performing the LookAt, like so:

transform.LookAt( target );
transform.Rotate( -90, 0, 0 );


b) make your visible object the child of a "dummy" empty game object, and rotate the child object by 90 degrees in the desired direction. Then perform the LookAt function on the empty parent game object.

hope this helps!

Z-Rotation, globally, determines the "up" direction (twisting around the line-of-sight axis). So, easy, just pass in the current up vector as the optional second argument:

transform.LookAt(target, transform.up);

I assume you're making 2d game?

You can use something like that

   var targetPoint: GameObject // gameobject to look to

      function Update()

            transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 0); // lock x and z axis to zero

Try using transform.eulerAngles . With that you can also lock your Z axis to other different degree. For example :

 transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 75); 

If you mean you want the LookAt feature but leave z fixed say z = fixedZ, I was able to do this with

transform.LookAt(Vector3(target.position.x , target.position.y , fixedZ)); 

or if you want the z to stay level with the transform

transform.LookAt(Vector3(target.position.x , target.position.y , transform.position.z));



I’ve been having a similar problems that I’m pulling my hair out with.

I have an object, say A, placed at the center which is intended to always point towards another orbiting object, say B. A needs to rotate along its Z-axis, with the X and Y axes being zero, furthermore, it is B’s X and Y changing coordinates that are used to compute A’s direction. I have used the following script:

Vector3 targetPosition = new Vector3(target.transform.position.x, target.transform.position.y, this.transform.position.z);

transform.Rotate(0, 90, 0);

Now this does the job, however the problem I have is that while A is rotating along its Z-axis, Y rotation flips from 0 to 180 (or sometimes -180) causing A to flip upside down. This happens as soon as the X coordinate of B changes from being positive to negative and vice versa. I’ve tried isolating the z rotation through another related object using A’s localEulerAngles but the flip in the Y axis distorts the z rotation in one instance going from -90 straight to 90, skipping 180 degrees.

If anyone has any suggestions I’d be much obliged.

Thank you
