Change GUI UI Background Color

I'm a newb to GUI UI, trying to change the Background color and something is not working:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using WBG;
6.  
7. public class btnStoreButtonClick : MonoBehaviour
8. {
9.     private Rect windowRect = new Rect((Screen.width - 400) / 2, (Screen.height - 200) / 2, 400, 200);
10.     private bool show = false;
11.     private string _Title;
12.     private string _Message;
13.     Color _WBGColor = new Color(91f, 203f, 188f, 10f);
14.  
15.     void OnGUI()
16.     {
17.         GUI.backgroundColor = _WBGColor;
18.         if (show) { windowRect = GUI.Window(4, windowRect, DialogWindow, _Title); }
19.     }
20.  
21.     // This is the actual window.
22.     void DialogWindow(int windowID)
23.     {
24.         GUI.Label(new Rect(5, 20, windowRect.width, 20), _Message);
25.  
26.         switch (windowID)
27.         {
28.             case 0:
29.                 if (GUI.Button(new Rect(320, 160, 50, 30), "OK"))
30.                 {
31.                     show = false;
32.                 }
33.                 break;
34.             case 1:
35.                 if(GUI.Button(new Rect(200, 160, 50,30), "Abort"))
36.                 {
37.                     show = false;
38.                 }
39.                 else if(GUI.Button(new Rect(260, 160, 50, 30), "Cancel"))
40.                 {
41.                     show = false;
42.                 }
43.                 else if (GUI.Button(new Rect(320, 160, 50, 30), "OK"))
44.                 {
45.                     show = false;
46.                 }
47.                     break;
48.             case 2:
49.                 if (GUI.Button(new Rect(270, 160, 50, 30), "Yes"))
50.                 {
51.                     show = false;
52.                 }
53.                 else if (GUI.Button(new Rect(330, 160, 50, 30), "No"))
54.                 {
55.                     show = false;
56.                 }
57.                 break;
58.             case 3:
59.                 if (GUI.Button(new Rect(270, 160, 50, 30), "Retry"))
60.                 {
61.                     show = false;
62.                 }
63.                 else if (GUI.Button(new Rect(330, 160, 50, 30), "Cancel"))
64.                 {
65.                     show = false;
66.                 }
67.                 break;
68.             case 4:
69.                 if (GUI.Button(new Rect(270, 160, 50, 30), "Help"))
70.                 {
71.                     show = false;
72.                 }
73.                 else if (GUI.Button(new Rect(330, 160, 50, 30), "OK"))
74.                 {
75.                     show = false;
76.                 }
77.                 break;
78.             default:
79.                 if (GUI.Button(new Rect(270, 160, 50, 30), "Yes"))
80.                 {
81.                     show = false;
82.                 }
83.                 else if(GUI.Button(new Rect(330, 160, 50, 30), "No"))
84.                 {
85.                     show = false;
86.                 }
87.                 break;
88.         }
89.     }
90.  
91.  
92.     public void ShowMessageBox(string Title, string Message)
93.     {
94.         _Title = Title;
95.         _Message = Message;
96.         show = true;
97.     }
98. }
99.  

I thought this was how you built color via rgb:

Code (CSharp):

1. Color _WBGColor = new Color(91f, 203f, 188f, 10f);

 

No, Color is a float from 0-1 Color32 is a byte from 0-255.

 

So use color32 instead of color to set the background color? Tried this but now the message box does not popup:

Code (CSharp):

1. Color32 _WBGColor = new Color32(91, 203, 188, 10);

Never mind I got it working now. How do you set the color for the rect and the title bar area?

 

Are you sure that it's not showing up? You have an alpha of 10 which is very low.

 

Hmm ok ill adjust the alpha and try again.
