I’m trying to make a shop where you can buy, for example, a different colored wheel. How would I do that, or something like it. Is there some sort of key word? I have the shop GUI set up, but I have no idea how I would make buttons that change the character. Thanks. Here’s the GUI code i have so far:

#pragma strict
 
var shop : boolean;
var money: float;
 
function Start () {
    shop = false;
}
 
function Update () {
    if(Input.GetKeyDown(KeyCode.Q)) {
       shop = !shop;
       money = 0;
    }
}
 
function OnGUI () {
 
    GUI.color = Color.green;
    GUI.Box (Rect (15,30,90,40), "Q: OPENS

SHOP");

    if(shop) {
        GUI.Box (Rect (110,25,300,300), "SHOP");
        GUI.Label(Rect(120, 35, 60, 20),"Money: " + money);
		       
    }
 
}

You can use buttons!
