Object not rotating

If you're wanting to rotate something continuously at a certain speed, google the Unity Script Reference. Once you're there, search for localEulerAngles. I'll give a basic example that will do this attach this script to any object you want to rotate.

 using UnityEngine;
 using System.Collections;
 
 public class Example : $$anonymous$$onoBehaviour
 {
     float rotationSpeed = 120.0f;
     Vector3 axis = Vector3.up;
     
     void Update()
     {
         transform.localEulerAngles += axis * rotationSpeed * Time.smoothDeltaTime;    
     }
 }

If you wish to do this in JS:

 #pragma strict
 
 var rotationSpeed : float = 120.0f;
 private var axis : Vector3 = Vector3.up;
 
 function Update()
 {
     transform.localEulerAngles += axis * rotationSpeed * Time.smoothDeltaTime;    
 }
