Question by OptimisticCode · Nov 27, 2013 at 05:39 AM · functions

Problem calling another scripts function (JS)

So I have a script A trying to call script B's function. I get a NullReference because I am not able to get the script correctly, but I've followed the exact stuff I've seen on the forums. Why am I having such a problem with this?

Script A:

 var diamManager : DiamondManger;
 var diam : int;
 diamManager = gameObject.GetComponent("DiamondManger");
 
 function OnGUI() {
     
     diam = diamManager.Diamonds();
 }

Script B:

  public function Diamonds(){
     Debug.Log("diamonds = " + diamonds);
     return diamonds;
  }

the diam line in the OnGui function is where I am getting my NullReference error.

 var diamManager : DiamondManger; 

just assign the script in the inspector and don't want this

 diamManager = gameObject.GetComponent("DiamondManger");

The problem to this is I the inspector will not let me assign the script. It just wont let me drag into it with the correct script

Checked it, doubled checked it, even changed it to a lowercase first letter. Nothing. I know right? In monodevelop it doesnt even turn blue... hint?

You need to put the "diamManager =" line inside the Start() function. The object/script hasn't been fully initialized when you call GetComponent so the component you are looking for doesn't exist yet.

The problem with this is, it is not recognizing Diamond$$anonymous$$anger as a type now... Error is in the first line
