Toggle Sound On/Off

Unity Engine
1

Hi there All,

I did a quick search but couldn’t find anything that looked like it was what I needed, but here we go…

I’m trying to make a GUI.Button that when clicked, disables the Audio.Listener on the Main Camera. I think I understand the basic fundamentals of the code that I need. Here is what I think it should look like, though I know it is incorrect.

// Start

var AudioListener : boolean;

function OnGUI()
{
var buttonName:String = "Sound is ";

if(GUI.Button(Rect(0, 0, 200, 100), “Sound On/Off”))
{
if (AudioListener == true)
AudioListener = false;
else
AudioListener = true;
}

}

// End

When I attach this script to the Main Camera and manually remove the default Audio Listener, I can run the program. And when the GUI button is pressed I can see the check-box checking and unchecking in the inspector but I get no sound. If I click on components and re-add the Audio->Audio Listener sounds are back but cannot be disabled.

Perhaps I"m not too far off but maybe using the wrong variables/calls?

Thanks in advance!

I was able to fix this issue by using:

//Start

function OnGUI()
{
var buttonName:String = "Sound is ";
var volume : float;

if(GUI.Button(Rect(0, 0, 100, 25), “Sound On/Off”))
{
if (audio.volume == 1.0)
audio.volume = 0.0;
else
audio.volume = 1.0;
}

}

//Finish
