Question by ragnaros100 · Mar 14, 2012 at 04:23 PM · arraygetcomponentforeachvoiddefine

Definition problem

I have a very complex and complicated script.(consist of more scripts actually, but lets focus on this single one)But cut down, I want to activate another public void in another script from this one: The problem is that, when I run PickMeUp I get a NullRefferenceException error. It apears that I havent defined the PrivatePositionUpdate variable.

 public GameObject ThisGameobject;
 public Private_position_Update PrivatePositionUpdate;
 public GameObject[] obstacles ;
 
 void Awake()
 {
     obstacles = GameObject.FindGameObjectsWithTag("obstacle");
     Debug.Log(obstacles);
 }
 void PickMeUp()
 {
     foreach (GameObject _obstacle in obstacles) {
         PrivatePositionUpdate = _obstacle.GetComponent<Private_position_Update>();
         Destroy(ThisGameobject);
         PrivatePositionUpdate.RemoveOfGadget();
     }
     
 }

}

I need an answer pretty badly on this... I have a deadline next week on this game and this is part of a major core game mechanic.

You need to have a script/class called Private_position_Update added to your obstacle gameobject.

Also I suggest checking if _obstacle is not null, and if PrivatePositionUpdate is not null.

Also why you are naming a class 'Private_position_Update' is beyond me.

Look at this link http://unity3d.com/support/documentation/ScriptReference/index.Accessing_Other_Game_Objects.html

Or this link http://answers.unity3d.com/questions/47705/how-to-access-variable-from-another-c-script-file.html

Thank you $$anonymous$$eltdown. It was helpfull, but not the exact thing I was looking for... $$anonymous$$y problem is that my gameobject gets destroyed before it can send the message out to my Private_position_Update script. And moving the Destroy(ThisGameobject); doesnt work

I know that in javascript I'd use var SomethingSomething = GetComponent("ScriptName")... And so on.
