Hi,
I have 1 GUI.Box and 3 GUI.Buttons, I want to change on run time the text and the color of the GUI.Box depending on the button clicked. How can I do that? I have tried but no luck, here is my NON working code.

void OnGUI() {
GUIStyle textFieldStyle = new GUIStyle();

string text;
text="";

	if (GUI.Button (new Rect (Screen.width * .01f, Screen.height * .24f, Screen.width * .32f, Screen.height * .24f), "RED")){
		textFieldStyle.normal.textColor = Color.red;
		text = "RED";
	}
	if (GUI.Button (new Rect (Screen.width * .34f, Screen.height * .24f, Screen.width * .32f, Screen.height * .24f), "YELLOW")){
		textFieldStyle.normal.textColor = Color.yellow;
		text = "YELLOW";
	}
	if (GUI.Button (new Rect (Screen.width * .67f, Screen.height * .24f, Screen.width * .32f, Screen.height * .24f), "BLUE")){
		textFieldStyle.normal.textColor = Color.blue;
		text = "BLUE";
	}
	GUI.Box(new Rect (Screen.width * .01f, Screen.height * .01f, Screen.width * .98f, Screen.height * .22f), text, textFieldStyle);
}

Thanks!

Unfortunately, if to use standard GUI.Box, its color of a texture practically can’t be changed (because a texture almost black with an alpha the channel to 50%). Though text color changes. So, at first it is necessary to create, for example, in Photoshop, a white texture of 16x16 in size. To make the style for GUI.Box on the basis of the made texture. And to add the following code in your script:

 public GUIStyle mystylebox = null; // your new style for box
 private Color colorbox = Color.white;

 void OnGUI() {
  GUI.color = Color.white;
  if (GUI.Button (new Rect (Screen.width * .01f, Screen.height * .24f, Screen.width * .32f, Screen.height * .24f), "RED")) {
   colorbox = Color.red;
   text = "RED";
  }
  if (GUI.Button (new Rect (Screen.width * .34f, Screen.height * .24f, Screen.width * .32f, Screen.height * .24f), "YELLOW")) {
   colorbox = Color.yellow;
   text = "YELLOW";
  }
  if (GUI.Button (new Rect (Screen.width * .67f, Screen.height * .24f, Screen.width * .32f, Screen.height * .24f), "BLUE")) {
   colorbox = Color.blue;
   text = "BLUE";
  }
  GUI.color = colorbox;
  GUI.Box(new Rect (Screen.width * .01f, Screen.height * .01f, Screen.width * .98f, Screen.height * .22f), text, mystylebox);
 }

I hope it to you helped.
