Flash AS3 OOP = Can 1 objects class find and change another objects xy properties?

Question

What I have is a game with a Level object, inside the Level is a Player object, and they don't have instance names given, what I'm trying to figure out is how to do is make it so that the player can change the x or y properties of the Level object.
To be more precise, I'm making it so that when the player moves in a certain direction, he either moves accross the stage, or he starts moving the Level object around the stage, it'd be in an Event kind of function, now I can easily make the Player move, but I don't know how to make the Level object move which the player is inside of.
Is anyone able to help me on this please?

Answer 1

I tried a simple getter setter idea, but it doesn't seem to work
public class Mover
  private var _moveValue:Number = 5;
public function Mover()
  Player.shift = _moveValue;
public class Player
private var _vx = 0;
public static function set shift (_move:number):void
  _vx = _move;
public function Player
addEventListener(Event.ENTER_FRAME, onEnterFrame);
function onEnterFrame(event:Event):void
x += _vx;
Thats with my limited imagination and knowledge of AS3 here so far... is that going completely wrong? If so are there any good examples or tutorials I could check out to get a better idea of what I'm trying to do?
