Rotating Image

Unity Engine
1

How would I rotate an image to a specific desired angle on the Z axis?

2

For smoothing use Quaternion.Lerp. To go to a specific angle rotation use Quaternion.Euler and pass that to the Lerp function.

3

An example using a transform would be like:

No Smoothing:

// x, y, z
transform.rotation = Quaternion.Euler(0,0,0);

Smoothing:

transform.rotation = Quaternion.Lerp (transform.rotation, Quaternion.Euler(0,0,0), speed);

Hope it helped.
