How do I make GUI buttons draw more GUI objects when clicked?

Questions & Answers

A while ago I made the code for a GUI menu which I unfortunately lost, so I’ve had to start again. This time though, I’m using the GUI.Window system, which I hadn’t noticed before (previously I’d used Boxes). However when running the program either in the Editor or as a standalone, only the Quit button is drawn. If I click that, the appropriate Debug messages appear, but it doesn’t seem to draw the Windows. So how can I get this to work properly? The answer’s probably staring me in the face, but I’d really appreciate an answer.

Code:

#pragma strict

var miniWindowDimensions : Rect = Rect((Screen.width/2)-(Screen.width/10),(Screen.height/2)-(Screen.height/10),Screen.width/5,Screen.height/5);
public var close : Texture;
public var freezeLayerOne : boolean = false;
function OnGUI()
{
	if(GUI.Button(Rect(Screen.width*0.6, (Screen.height/20)*18, Screen.width/3, Screen.height/10), "QUIT") && freezeLayerOne == false)
	{
		print("Quit pressed");
		freezeLayerOne = true;
		GUI.Window(0,Rect(miniWindowDimensions),sureQuitCreate,"Are you sure?");
	}
}

function sureQuitCreate(windowID : int)
{
	if(GUI.Button(Rect((Screen.width/2)+(Screen.width/20)*15,(Screen.height/2)-(Screen.height/10)+2,20,20),close))
	{
		freezeLayerOne = false;
		print(freezeLayerOne);
	}
	if(GUI.Button(Rect(0,0,40,40),"QUIT"))
	{
		Application.Quit();
	}
}

I have absolutely no idea why this doesn’t work, but I managed to get it to work by using a boolean and then checking its state and rendering on the condition that it’s true. So like this:

#pragma strict

var miniWindowDimensions : Rect = Rect((Screen.width/2)-(Screen.width/10),(Screen.height/2)-(Screen.height/10),Screen.width/5,Screen.height/5);
public var close : Texture;
public var freezeLayerOne : boolean = false;
var canRenderWindow : boolean = false;

function OnGUI()
{
    if(GUI.Button(Rect(Screen.width*0.6, (Screen.height/20)*18, Screen.width/3, Screen.height/10), "QUIT") && freezeLayerOne == false)
    {
       print("Quit pressed");
       freezeLayerOne = true;
       canRenderWindow = true;
    }
    
    if(canRenderWindow) {
    	miniWindowDimensions = GUI.Window(0,Rect(miniWindowDimensions),sureQuitCreate,"Are you sure?");
    }
}

function sureQuitCreate(windowID : int)
{
    if(GUI.Button(Rect((Screen.width/2)+(Screen.width/20)*15,(Screen.height/2)-(Screen.height/10)+2,20,20),close))
    {
       freezeLayerOne = false;
       canRenderWindow = false;
       print(freezeLayerOne);
    }
    if(GUI.Button(Rect(0,0,40,40),"QUIT"))
    {
       Application.Quit();
    }
}

Hope that helps! Klep
