Problem calling another scripts function (JS)

Archived Forums Questions & Answers

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

 –

that means, check the spelling of script name

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 DiamondManger as a type now... Error is in the first line
