Change GUI Button for Image

Hi guys im working on a game and in my character selection i hv some buttons wish i want to add diferent images to them but im not finding the right way: this is part of the code and can be used for exemple: i hv a grid with 6 boxes wish i want to add 1 image to each one. can anyone help me plz?

Code (CSharp):

1.     public void DisplayClassSelections()
2.     {
3.         //A list of toggle buttons nad each button will be a diference class
4.         //Selection grid
5.         classSelection = GUI.SelectionGrid (new Rect (50,50, 250, 300), classSelection, classSelectionNames, 2);    //2 at end indicate the number of squares per line in class selection
6.         GUI.Label(new Rect(450, 50, 300, 300), FindClassDescription(classSelection));
7.         GUI.Label(new Rect(450, 100, 300, 300), FindClassStatValues(classSelection));

 

You'll probably want to use the overload of SelectionGrid that takes an array of GUIContent. GUIContent can define the text and image(texture) for a given item in the grid.

Code (csharp):

1.  
2. static int SelectionGrid(Rect position, int selected, GUIContent[] content, int xCount);
3.  

Code (csharp):

1.  
2. // new field in class.
3. public Texture[] classTextures; // assign in inspector with texture.
4. // other code
5.  
6. public void DisplayClassSelections()
7. {
8.   //A list of toggle buttons nad each button will be a diference class
9.   //Selection grid
10.   classSelection = GUI.SelectionGrid (new Rect (50,50, 250, 300), classSelection, ConstructContent(), 2);
11.   // your other code
12. }
13.  
14. private GUIContent[] ConstructContent()
15. {
16.    return new GUIContent[]
17.    {
18.      new GUIContent(classSelectionNames[0], classTextures[0]),
19.      new GUIContent(classSelectionNames[1], classTextures[1]),
20.      new GUIContent(classSelectionNames[2], classTextures[2]),
21.      new GUIContent(classSelectionNames[3], classTextures[3]),
22.      new GUIContent(classSelectionNames[4], classTextures[4]),
23.      new GUIContent(classSelectionNames[5], classTextures[5])
24.    };
25. }
26.  

something like that

 

the question is that script is not monobehavior so i cant sign it to inspector... this is the full script... wt can i do in this situation? ty

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;

check unity documentation for GUI.Skin or GUI.Style hopefully this will help , they allow you to customize your unity GUI anyway you want.

 

Even use diferent images at same same time?

 

Yes but each button must have it's own style , to have different images.
you should check some other UI tools on the asset store , NGUI is a great solution plus it's much easier to use and in a game with lots of UI should provide a boost to your frame rate since it doesn't have as many draw calls as unity's native UI do.

 

But if i go to NGUI i will hv to remake the code right? ty for help

 

Probably but it will make your life easier later on once you get used to it
