Trying to change button background using materials

In my project I want to be able to change background of a button by using the action performed of another button. I was curious as to if using textures or materials would be the best route for this.

Doing so I have code so far as to what I am trying to do. The four buttons will work for a single action but I would like to be able to to keep using if I choose a button and then want to go back to the previous selection by pressing that button.

Please help, (in UnityScript) I am sure this is an easy fix, I am just not seeing it! Thanks again

var materials : Material;

//Dimensions for the Materials UI

private var glassOptionButton : Rect = Rect(10,20, 50,50);

private var stoneOptionButton : Rect = Rect(65,20, 50,50);

private var brickOptionButton : Rect = Rect(10,72, 50,50);

private var paintedDrywallOptionButton : Rect = Rect(65,72, 50,50);

private var copperOptionButton : Rect = Rect(10,125,50,50);

// Boolean vars for the different materials

private var isGlass : boolean = false;

private var isStone : boolean = false;

private var isBrick : boolean = false;

private var isDryWall : boolean = false;

function OnGUI()
{

GUI.Window(1,materialsWindow, materialsWindowFunc, “Material Window”);

}

function materialsWindowFunc(windowID: int)
{

if(GUI.Button(glassOptionButton, “GL”))
{
isGlass = true;

if(isGlass == true)
{
textureButton = materials[2];
}
Debug.Log(textureButton);
}
if(GUI.Button(stoneOptionButton, “STO”))
{
isStone = true;

if(isStone == true)
{
textureButton = materials[5];
}
Debug.Log(textureButton);
}
if(GUI.Button(brickOptionButton , “BR”))
{
isBrick = true;

if(isBrick == true)
{
textureButton = materials[0];
}
Debug.Log(textureButton);
}
if(GUI.Button(paintedDrywallOptionButton, “PDW”))
{
isDryWall = true;

if(isDryWall == true)
{
textureButton = materials[3];
}
Debug.Log(textureButton);
}

}

you need to reset booleans as they are all staying true. Each button needs to set the other booleans to false when you click them. this should allow you to reuse the buttons. ie

`if(GUI.Button(paintedDrywallOptionButton, “PDW”)) {

isDryWall = true;

isBrick = false;

isStone = false;

isGlass = false;

if(isDryWall == true) {

textureButton = materials[3];

}

Debug.Log(textureButton);

}`
