AS3 – Convert seconds to ww:dd:hh:mm:ss

function convertTime(number:Number):String { number = Math.abs(number); var values:Array = new Array(5); values[0] = Math.floor(number / 86400 / 7);// weeks values[1] = Math.floor(number / 86400 % 7);// days values[2] = Math.floor(number / 3600 % 24);// hours values[3] = Math.floor(number / 60 % 60);// mins values[4] = Math.floor(number % 60);// secs


    var stopage:Boolean = false;

    var cutIndex:Number = -1;
    for (var i:Number = 0; i < values.length; i++)

        if (values[i] < 10)

AS3 referencing Main/Document class as Singleton||Monostate

me — Tue, 20 Dec 2011 20:45:46 +0000

public class Main extends Sprite {


    private static var _instance:Main;

    public static function get instance():Main { return _instance; }
    public function Main() {

        _instance = this;

       // etc...

    }
    // etc...

}
Then you access the Main instance like this:

public class Other { public function Other() { Main.instance.usefulInstanceMethod(); } }
