I have a problem with the MouseLook script. When i press Esc the pause menu comes up but i cant disable the FPS-MouseLook. I have the JS version of MouseLook. I set the script on Main Camera and FPS Controller. But it says:

.

NullReferenceException: Object reference not set to an instance of an object  
Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.String cacheKeyName, System.Type cacheKeyTypes, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory)  
Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.Object args, System.String cacheKeyName, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory)  
Boo.Lang.Runtime.RuntimeServices.GetProperty (System.Object target, System.String name)  
UnityScript.Lang.UnityRuntimeServices.GetProperty (System.Object target, System.String name)  
MouseDisable.Update () (at Assets/Scripts/MouseDisable.js:6)

.

.

This is the script i wrote, please help?

```
function Update () 
{ 

	if(Input.GetKeyDown("escape"))
	{
		GetComponent("MouseLook").enabled = !GetComponent("MouseLook").enabled;
	}
	
}

```

Make sure this script is on the exact same object as MouseLook. Otherwise, you may want to GameObject.Find and/or use GetComponentInChildren
