Rotate cube according to position of another object?

Question

I have a level as shown below. alt text

I want to press any arrow key and the blue cube will 'rotate' or move position to same position but on a different face of the white cube. alt text

I want this to work so whatever arrow key you press it will move it to the same relative position but on a different face of the white cube. I can't figure out how to manage this any help is much appreciated.

You can parent an object to another object, and it will move along with it. So, when you press a key, set the blueCube to be a child of another transform of your choosing. Then perform the animation on the new-parent. If you keep world position when stetting the parent, the object will stay put, even though it "follows" a different object.

 // ...pick a newParentTransform
 blueCube.transform.SetParent(newParentTransform, worldPositionStays=true);
 // ...play an animation that does the rotation

Another possible approach is to set the rotation directly with Transform.RotateAround
