How to display gui.texture from a different script

Questions & Answers
1

I’m trying to do a simple player lives/powerups/whatever display using Unity textures. I want to create one GUI script that takes the variables from other scripts. I was able to succesffuly create a health bar using this method, but I’m hung up on grabbing a variable (player teddypowerup) and displaying it using the other script. Here’s what I have so far, where am I going wrong?

  1. Create a Gui gameobject and attach this script:
var TeddyTexture : Texture2D;

function Update () {
	guiTexture.texture = TeddyTexturGamecontroller.PowerUpTeddy];
}

//@script ExecuteInEditMode

It’s grabbing the variable ‘PowerUpTeddy’ from the GameController script

var player : GameObject;
//var guiSkin : GUISkin;
var spawnPoint  : Transform;
public var mainCam : Camera;
public var StartSpawn : boolean=true;
var pos : Vector2 = new Vector2(20,40);
var size : Vector2 = new Vector2(60,20);

static var PowerUpTeddy = 1;
static var Costume = 0;

function Awake() {
  if(!spawnPoint){spawnPoint= transform;}
  if(!mainCam){mainCam=Camera.main;}
  if(StartSpawn){
    var curPlayer:GameObject=Instantiate(player, spawnPoint.position, transform.rotation);
  }
  mainCam.gameObject.GetComponent(cam).target =curPlayer;
  var PowerUpTeddy = 1;
}

The following code generates a “Array out of scope error” even if I instantiate the script to ‘1’

I’ve also tried to just call the script component directly from the Guiscript using this code:

gameObject.Find("GameController").GetComponent(Gamecontroller);

I’m able to find the script component, but I’m unsure what to do with it. I tried to do this to attach the variable to my texture, but got an error:

GUI.DrawTexture(Rect(600,410,100,100), PowerupTeddy, ScaleMode.ScaleToFit, true, 10.0f.GameController.PowerUpTeddy); //I guess you can't call the variable using this method:

So my long winded question: What is the best way to display GUI elements that rely on variables to display? IE health, current weapon, etc. Thanks in advance for any help.

Side note: I’ve also t

guiTexture.texture = TeddyTexturGamecontroller.PowerUpTeddy];

] at the end, remove it.

Also, you declare static var PowerUpTeddy

but use var PowerUpTeddy = 1;

You actually declare a new variable in the Awake()

And make sure you spell the variables right you wrote PowerupTeddy in the last example.
