Help! Hiding/showing GUITextures!

Questions & Answers
1

So I’m working on a game in Unity using javascript. My problem is I can’t seem to figure out how to activate a GUITexture that is not attactched to the certain texture (External Script).

So here I have my script for my button which is called Upgrade.js

 var normalTexture : Texture;
 var hoverTexture : Texture;
 var pressedTexture : Texture;
 var messagee : GameObject;
 var message = "ButtonPressed";
 
 private var state = 0;
 private var myGUITexture : GUITexture;
 
 myGUITexture = GetComponent(GUITexture); 
 
 function OnMouseEnter()
 {
    state++;
    if (state == 1)
        myGUITexture.texture = hoverTexture;
 }
 
 function OnMouseDown()
 {  
     state++;
    if (state == 2)
        myGUITexture.texture = pressedTexture;
		
		var window = gameObject.Find("WindowUpgrade");
		
		if(window.active == false){
			window.setActive = true;
		}
 }
 
 function OnMouseUp()
 {
    if (state == 2)
    {
        state--;
        if (messagee)
            messagee.SendMessage(message, gameObject);
    }
    else
    {
        state --;
        if (state < 0)
            state = 0;
    }
    myGUITexture.texture = normalTexture;
 }
 
 function OnMouseExit()
 {
    if (state > 0)
        state--;
    if (state == 0)
        myGUITexture.texture = normalTexture;
 }

The problem is with the OnMouseDown function!

Here is the other script, CloseBox.js:

#pragma strict

function Update(){
	
	if (Input.GetKeyDown("c")){
		
		guiTexture.active = false;
	}
	
}

The error I get is “NullReferenceException: object reference not set to an instance of an object”

Any help is much appreciated!

Thanks!

Assume that your first script is attached to a game object with a unique name like “Upgrade” you can replace line 7 in the second script with:

GameObject.Find("Upgrade").guiTexture.active = false;

If the game object has a unique tag, you can use FindWithTag() instead of Find().
