Question by Devilfish · Sep 25, 2015 at 02:28 AM · missingreferenceexception

Missing reference on loadLevel when the object exist...why? :(

When I call LoadLevel(level), every level have an object called Traveller, I suppose that on-loading, the last level was destroyed and new level load all object that contain the new scene, I dont undestand why getComponent cant find my script attached to my Traveller object, if this exist in the new scene. here is an screenshot:

 void Start () {
     traveller = GameObject.FindGameObjectWithTag("Traveller").transform;
     travellerController = traveller.GetComponent<TravellerController> ();

GameController isDontDestryOnLoad, right? run your above code on Start not Awake.

Start is only called once.

This means that if you have an object that's DontDestroyOnLoad-ed, it won't call Start again when you change your scene.

So your GameController is still referencing the now-destroyed traveller from the last scene.

To fix this, call the same code as you're calling in Start in OnLevelWasLoaded.

EDIT: Also don't post questions with all-caps headlines, as that's super-annoying, and more likely to have people ignore your question than answering it.

Yeah, sorry about caps :P. I think the problem is in the design, because every scene has a gamecontroller ( levelcontroller ). So I will change to masterController (make this one persistant in all scenes ) and maybe fix this issue, thanks mate :)
