Question

How does it work the GUI toggle?

I want to be able to switch between two textures if the toggle is on or off.

The GUI.Toggle is described on this page in the manual and here in the scripting reference.

If you want something to happen when toggling the toggle, here is one way to do it:

var toggleBool = true;

function OnGUI () {
    var toggleBoolNew = GUI.Toggle (Rect (25, 25, 100, 30), toggleBool, "Toggle");

    // Check if the toggle was toggled
    if (toggleBoolNew != toggleBool) {
        if (toggleBoolNew == true)
            Debug.Log("Toggle was enabled");
        else
            Debug.Log("Toggle was disabled");

        toggleBool = toggleBoolNew;
    }
}

Thanks..now I understand how to activate functions regarding the on/off state of the toggle

== true could be omitted and consider adding the curly brackets {} even if you have only one line to execute.. because usually you don't have only one.. for example.. what if you want to add the code for changing the texture and see Debug.Log("Texture was changes")..

@Lipis I added == true to make the code more readable - this language construct is not obvious for people new to programming, for example. But you're right that it can be left out. About where to use curlies, that is a matter of taste.

what if I only want to play a sound once using toggle button??because I tried your code and the sound keeps playing...

How do I make it done once??

PROBLEM SOLVED : by adding a conditional statement before setting the boolean to true I'm able to set the toggle to play the sound only once.
