unity transform.rotate function code example

Example 1: how to change rotate with script unity

var rotationVector = transform.rotation.eulerAngles;
rotationVector.z = 0;  //this number is the degree of rotation around Z Axis
transform.rotation = Quaternion.Euler(rotationVector);
//if you put this in a coroutine and yielding for some amount of time 
//you can have something like a rotating loading icon

Example 2: transform.rotation.x unity

transform.eulerAngles = new Vector3( xRotation, transform.eulerAngles.y, transform.eulerAngles.z );
