I never entirely understood this error, I just know it’s bloody irritating, but here’s the code it’s complaining about:

var graphicsComponent: Transform;
var cameraComponent: Transform;

function Start () {
	if(graphicsComponent.networkView.isMine){
		GetComponent("FPSInputController").enabled = true;
		GetComponent("CharacterMotor").enabled = true;
		GetComponent("MouseLook").enabled = true;
		cameraComponent.camera.enabled = true;
		cameraComponent.GetComponent("MouseLook").enabled = true;
		cameraComponent.AudioListener.enabled = true;
	}
}

function OnDisconnectedFromServer() {
	DestroyObject(gameObject);
}

And the full error report:

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.SetProperty (System.Object target, System.String name, System.Object value) OwnerControl.Start () (at Assets/Standard Assets/Scripts/Networking Scripts/OwnerControl.js:11)

Anyone know what I’m doing wrong?

I believe that almost every line of your script could be wrong:

Line 5 - graphicsComponent could be null if it is not set in the inspector yada yada
Line 6 - GetComponent could return null if no FPSInputController is added to the GO yada yada.
Line 7 - GetComponent could return null if no CharacterMotor is added to the GO yada yada.
Line 8 - GetComponent could return null if no MouseLook is added to the GO yada yada.
Line 9 - cameraComponent could be null if it is not set in the inspector yada yada.
Line 10 - again, GetComponent could return null yada yada.
Line 11 - cameraComponent could be null if it is not set in the inspector or it might not have an AudioListener yada yada.
Line 16 - what’s gameObject yada yada?
