Two GUI popups - 1st one needs to be destroyed

I was wondering how I would work out the following situation: I have an NPC that generates a GUI depending on a particular variable. However, the following code generates both GUI's rendering at the same time... by both I mean: there's one that should appear when the variable no_coop_button is set to true and another to appear when the npc_trigger is set to true. I'm not sure how to generate these GUI's separately.

Code (csharp):

1. function OnGUI()
2. {
3.     if (no_coop_button)
4.     {
5.         GUI.BeginGroup (Rect (Screen.width / 2 - 50, Screen.height / 2 - 50, 100, 100));
6.         GUI.Box (Rect(0, 0, 100, 100), "You are \n a thief");
7.         GUI.EndGroup ();
8.     }
9.  
10.     if (npctrigger)
11.     {
12.     GUI.BeginGroup (Rect (Screen.width / 2 - 50, Screen.height / 2 - 50, 100, 100));
13.     }
14.    
15.     if (yesbutton)
16.     {
17.         GUI.Box (Rect(0, 0, 100, 100), "Enter \n treasure \n chest");
18.         Destroy(this, 5.0f);
19.     }
20.    
21.     else if (nobutton)
22.     {
23.         GUI.Box (Rect(0, 0, 100, 100), "You \n cannot \n enter");
24.         Destroy(this, 5.0f);
25.     }
26.    
27.     else
28.     {
29.         GUI.Box (Rect(0, 0, 100, 100), "Give inventory?");
30.         if (GUI.Button (Rect(25, 25, 50, 30), "Yes"))
31.         {
32.             yesbutton = true;
33.             Debug.Log("True");
34.         }
35.  
36.         if (GUI.Button (Rect(25, 65, 50, 30), "No"))
37.         {
38.             nobutton  = true;
39.             Debug.Log("No");
40.         }
41.     }
42.     GUI.EndGroup ();
43. }
44.  

 

The npctrigger check only outputs one line :

GUI.BeginGroup (Rect (Screen.width / 2 - 50, Screen.height / 2 - 50, 100, 100));

Which doesn't do anything visually, even though you said that it's supposed to show up a menu.

The rest of your checks (yesbutton, nobutton and else) are outside the two if statements at the top. Nest them at their appropriate place.
