Research & Development for 3D & the Web

This is a very useful script to use when you want to be able to choose when / how to pass a game object onto another scene and then be able to return to a previous scene without ending up with duplicate objects.

(The script was taken from Unity Answers area on their site at the address below:)

private static var instance:MusicHandler;

public static function GetInstance() : MusicHandler
{
return instance;
}

function Awake ()
{
if (instance != null && instance != this)
{
Destroy(this.gameObject);
return;
}
else
{
instance = this;
}

DontDestroyOnLoad(this.gameObject);
}
