rigidbody.MoveRotation neither world space or local? How does it work?

Question

Hi, I have a script that is supposed to change the rigidbody along the X or Y axis depending on what mouse button you press. But the Y axis rotation seems to be in world space and the X axis it seems to be in local space. How do I get the whole thin in world space? (I need to use rigdbody.MoveRotation and not transform.EulerAngles because of strange collision events.)

Here is part of my script:

 if (Input.GetMouseButton (0)   && Time.time > nextRot) {
             
             nextRot = Time.time + rotRate;
             
                 
             rotX = rotX + 90;
             if (rotX > 315) rotX = 0;
             if (rotX >= 225 && rotX < 315) rotX = 270;
             if (rotX >= 135 && rotX < 225) rotX = 180;
             if (rotX >= 45 && rotX < 135) rotX = 90;
             if (rotX >= 0 && rotX < 45) rotX = 0;
             Debug.Log ("rotX = " + rotX);
                 
             
             xCanRot = true;
         }
             else xCanRot = false;
             
             
         if (Input.GetMouseButton (1)   && Time.time > nextRot) {
             
             nextRot = Time.time + rotRate;
             
                 
             rotY = rotY + 90;
             if (rotY > 315) rotY = 0;
             if (rotY >= 225 && rotY < 315) rotY = 270;
             if (rotY >= 135 && rotY < 225) rotY = 180;
             if (rotY >= 45 && rotY < 135) rotY = 90;
             if (rotY >= 0 && rotY < 45) rotY = 0;
             Debug.Log ("rotY = " + rotY);
             
                 
             yCanRot = true;
         }
             else yCanRot = false;
                 
             
     
     if (yCanRot || xCanRot) {
     
             
             
             blockRotation = Quaternion.Euler (Vector3 (rotX,rotY,0.0));
             rigidbody.MoveRotation(blockRotation);
             
     
             
         }

I think I have figured it out. I was using Euler Angles and they (I think) rotate in a sequence of axis and can change the Euler angle values as they go. I have used them very effectively before for rotation about a single axis (A dial from one to 10). But they are really bad for incrementing movement in 3D.

Now for this project, I am using Transform rotation as below:

 #pragma strict
 
 
 
 var canRot: boolean;
 
 private var emptyRotation: Quaternion;
 
 
 function Start () {
 
 canRot = false;
 emptyRotation = Quaternion.identity;
    
 }
        
     
     function Update () {
     
             
         if (Input.GetMouseButtonDown (0)   ) {
             
             transform.Rotate (Vector3.right * 90 , Space.World);
                                            
         }
             
             
         if (Input.GetMouseButtonDown (1)   ) {
                                 
                 transform.Rotate (Vector3.up * 90 , Space.World);
             
         }
             
         emptyRotation = transform.rotation;
     }

rigidbody.MoveRotation neither world space or local? How does it work?
