GUI.Window not displaying Buttons

Question

UPDATE : I've updated the script once again. Also, I tested a few things, and I put the hSlider right under where I define what the selectedToolbar is. It appeared when it was there... Any ideas?

using UnityEngine; using System.Collections;

public class Options : MonoBehaviour {

   private Rect windowRect = new Rect(200, 200, 1200, 500);
     private int selectedToolbar = 0;
     private string[] toolbarStrings = { "Quality", "Sound", "Game Size", "Menu" };
     public float hSliderValue = 0.0f;
     private bool IsOptionsAvailable = false;
     private int MyCurrentRes;
 
     void Start()
     {
        
     }
 
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.O) && IsOptionsAvailable == false)
         {
             IsOptionsAvailable = true;
             Debug.Log ("Show Options");
         }
         else if (Input.GetKeyDown(KeyCode.O) && IsOptionsAvailable == true) 
         {
             IsOptionsAvailable = false;
             Debug.Log("Hide Options");
         }
 
     }
 
     void OnGUI()
     {
         if (IsOptionsAvailable)
         {
             windowRect = GUI.Window(0, windowRect, WindowFunction, "Options");
         }
     }
 
     void WindowFunction(int windowID)
     {
         GUILayout.BeginHorizontal();
         selectedToolbar = GUILayout.Toolbar(selectedToolbar, toolbarStrings);
         
         if (GUI.changed)
         {
             Debug.Log("Toolbar was clicked");
 
                 if (selectedToolbar == 0)
                 {
                     Debug.Log("Graphics selected");
                     GUILayout.BeginVertical();
                     string[] names = QualitySettings.names;
                     int i = 0;
                     while (i < names.Length)
                     {
                         if (GUILayout.Button(names[i]))
                             QualitySettings.SetQualityLevel(i, true);
 
                         i++;
                     }
                     GUILayout.EndVertical();
                 }
 
                 if (selectedToolbar == 2)
                 {
                     GUILayout.BeginVertical();
                     Debug.Log("Game size selected");
                     if (GUILayout.Button("Fullscreen Mode"))
                     {
                         MyCurrentRes = QualitySettings.GetQualityLevel();
                         Screen.SetResolution(1680, 1050, true);
                         QualitySettings.currentLevel = QualityLevel.Fantastic;
                         QualitySettings.SetQualityLevel(MyCurrentRes, true);
                         Debug.Log("Fullscreen");
                     }
                     else if (GUILayout.Button("Window Mode"))
                     {
                         MyCurrentRes = QualitySettings.GetQualityLevel();
                         Screen.fullScreen = false;
                         QualitySettings.currentLevel = QualityLevel.Fantastic;
                         QualitySettings.SetQualityLevel(MyCurrentRes, true);
                         Debug.Log("Window");
                     }
                     Resolution[] resolutions = Screen.resolutions;
                     foreach (Resolution res in Screen.resolutions)
                     {
                         if (GUILayout.Button(res.width.ToString() + " x " + res.height.ToString()))
                         {
                             MyCurrentRes = QualitySettings.GetQualityLevel();
                             Screen.SetResolution(res.width, res.height, false);
                             QualitySettings.currentLevel = QualityLevel.Fantastic;
                             QualitySettings.SetQualityLevel(MyCurrentRes, true);
                             Debug.Log(res.width.ToString() + " x " + res.height.ToString());
                         }
                     }
                     GUILayout.EndVertical();
                 }
                 if (selectedToolbar == 3)
                 {
                     Debug.Log("Go to Main Menu");
                     Application.LoadLevel("MainMenu");

                     GUI.Box(new Rect(140, 140, 200, 50), "Volume");
                     hSliderValue = GUI.HorizontalSlider(new Rect(40, 40, 600, 200), hSliderValue, 0.0f, 10.0f);
                     AudioListener.volume = hSliderValue;
                 }
             }
         GUILayout.EndHorizontal();
             GUI.DragWindow();
     }
 }

//OLD Question :I have a script that permits me to change the runtime qualitysettings and screen resolution. However, whenever I build the game, sometimes when I change the resolution the screen becomes black, or the camera gets uncalibrated (and mouse) and i have to select another quality setting to calibrate it. Any suggestions what this might be?

Answer 1

I fixed the problem, just completely re-arranged my script without the usage of a toolbar :

 using UnityEngine; using System.Collections;
 
 public class Options : MonoBehaviour { //Les options de GUI utilisent tous les commandes de UnirtEngine.GUI;
     private Rect windowRect = new Rect(Screen.width*0.2f, Screen.height*0.2f, 1200, 600);
     private int selectedToolbar = 0;
     public float hSliderValue = 0.0f;
     private bool IsOptionsAvailable = false;
     private int MyCurrentRes;
     private float MyCurrentSound;
     private Color guiColor;
 
     void Start()//On vas chercher les components comme le son afin de pouvoir le changer
     {
         hSliderValue = AudioListener.volume;
         guiColor = GUI.color;
     }
 
     void Update()// Si on tappe la touche O opur options, on vas pouvoir ouvrir le menu d'options
     {
         if (Input.GetKeyDown(KeyCode.O) && IsOptionsAvailable == false)
         {
             IsOptionsAvailable = true;
             Debug.Log ("Show Options");
         }
         else if (Input.GetKeyDown(KeyCode.O) && IsOptionsAvailable == true) 
         {
             IsOptionsAvailable = false;
             Debug.Log("Hide Options");
         }
     }
 
     void OnGUI()
     {
         if (IsOptionsAvailable)
         {
             windowRect = GUI.Window(0, windowRect, WindowFunction, "Options");
         }
     }
 
     void WindowFunction(int windowID)
     {
         GUILayout.BeginArea(new Rect(10, 10, 250, windowRect.height));// On commence une section qui nous permet de changer la qualité du jeux
                     GUILayout.BeginVertical();
         GUILayout.Button("Graphics");
         GUI.backgroundColor = Color.green;
         string[] names = QualitySettings.names;
                     int i = 0;
                     while (i < names.Length)
                     {
                         if (GUILayout.Button(names[i]))
                             QualitySettings.SetQualityLevel(i, true);
 
                         i++;
                     }
                     GUILayout.EndVertical();
         GUILayout.EndArea();
 
         GUILayout.BeginArea(new Rect(265, 10, 250, windowRect.height));// On commence une section qui nous permet de changer la résolution du jeux
         GUILayout.BeginVertical();
         GUI.backgroundColor = guiColor;
         GUILayout.Button("Game Size");
 
         GUI.backgroundColor = Color.red;
         if (GUILayout.Button("Fullscreen Mode"))
                     {
                         MyCurrentRes = QualitySettings.GetQualityLevel();
                         QualitySettings.SetQualityLevel(6, true);

                         Debug.Log("Fullscreen");
                     }
                     else if (GUILayout.Button("Window Mode"))

                         Debug.Log("Window");
                     }
                     Resolution[] resolutions = Screen.resolutions;
                     foreach (Resolution res in Screen.resolutions)
                     {

                             QualitySettings.SetQualityLevel(MyCurrentRes, true);
                             Debug.Log(res.width.ToString() + " x "

                         }
                     }

         GUILayout.EndArea();
 
         GUILayout.BeginArea(new Rect(520, 10, 250, windowRect.height));// On commence une section qui nous permet de retourner au menu/recommencer le jeux *PAS RECOMMENDER*
         GUILayout.BeginVertical();
         GUI.backgroundColor = guiColor;
