Question by TommyEaves2002 · Aug 10, 2015 at 08:54 PM · rotationrotatez axis

Rotate to Original Z Rotation

Hi, I need a way to rotate my object to its original rotation on the Z axis. I want it so that it rotates at a given speed (rotSpeed). If anybody could help it would be appreciated if you could do so.

Many Thanks,

Tommy Eaves

I think that the easiest way to do this is to create an empty object then parent your object to the empty. It should have the rotation set to zero. From there you can rotate the empty in any direction on any axis, without touching the rotation of your object.

I would look into first storing the Z position on "Start()" or at an appropriate time for you.

Second, I would look into

 transform.rotation.z

Finally for speed I would look into

 transform.Rotate(..., ...);

Here are some helpful links for you:

http://docs.unity3d.com/ScriptReference/Transform.Rotate.html

http://docs.unity3d.com/ScriptReference/Transform-rotation.html

All this should help you get started on learning what to do.

Use Mathf.SmoothDamp:

 private int zRot;
 private float velocity = Vector3.zero;
 public float rotSpeed;
 
 void Start()
 {
      zRot = transform.rotation.z;
 }
 
 void Update()
 {
      Quaternion.Euler (new Vector3 (transform.rotation.x, transform.rotation.y, Mathf.SmoothDamp (transform.rotation.z, zRot, ref velocity, rotSpeed)));
 }
