Hello,

here I'm stuck with quaternion usage (I know I'm not alone and that's reassuring... a bit:)).

I have a cube. I want to make this cube rotates from 90 degrees on X axis or Y axis in worldspace.

Here is the code I use in the cube script :

void Update() 
{
    if (transform.rotation == _nextRot)
    {
       _currentRot = transform.rotation;
       if (_onX == false)
       {
         _nextRot = transform.rotation * Quaternion.Euler(transform.up * 90);
         _onX = true;
       }
       else
       {
         _nextRot = transform.rotation * Quaternion.Euler(transform.right * 90);
         _onX = false;
       }
       _turntime = Time.time;         
    }
    transform.rotation = Quaternion.Slerp(_currentRot,_nextRot, (Time.time - _turntime) * 0.2f);
}

As I understand it, using transform.up or transform.right and multiplies it by my rotation gives me a new rotation in worldspace. However this code gives me a cube rotating on X one time then only on Y axis.

Any idea?
