Accessing variables

programming flash
1

Hi

Lets say we have the following code in Main.as


package {
    import flash.display.Sprite;
    import Player;
    public class Main  extends Sprite {
        public function Main() {
            public var deltaTime:uint;
            private var objPlayer:Player = new Player();
        }
    }
}

and the Player.as contains


package {
    import flash.display.Sprite;
    public class Player extends Sprite {
        public function Player() {
            x += 10*deltaTime;
        }
    }
}

But how do I access the deltaTime variable from Player function/Method?
I have tried root.Main.deltaTime and more, but no one seems to work.

Thanks in advance
