change variable value dynamically

[onenonly]

var game:Object = new Object;
game.Tile0.frame = 1;
game.Tile1.frame = 2;

animation.gotoAndStop(game.Tile+i+.frame);

need a way to change from tile0 to tile1 through variable




Real Example::

var myMap:Array = [
[1, 1, 1, 1, 1, 1, 1, 1], 
[1, 0, 0, 0, 0, 0, 0, 1], 
[1, 0, 1, 0, 0, 0, 0, 1], 
[1, 0, 0, 0, 0, 1, 0, 1], 
[1, 0, 0, 0, 0, 0, 0, 1], 
[1, 1, 1, 1, 1, 1, 1, 1]
];


var game:Object = new Object;
game = {tileW:30, tileH:30};

game.Tile0 = function () { };
game.Tile0.walkable = true;
game.Tile0.frame = 1;

game.Tile1 = function () { };
game.Tile1.walkable = false;
game.Tile1.frame = 2;

function buildMap(map) {

	var mainMC:empty = new empty();
	
	
	stage.addChild(mainMC);
	
	var mapWidth = map[0].length;
	var mapHeight = map.length;
	
	for (var i = 0; i<mapHeight; ++i) {
		for (var j = 0; j<mapWidth; ++j) {
			
			var D_tile:tile = new tile();
			D_tile.x = (j*game.tileW);
			D_tile.y = (i*game.tileH);
			
			
			
			
			
	
			D_tile.gotoAndStop(game.Tile+map[i][j]+.frame);
			
			mainMC.addChild(D_tile);
			

			
			
			
			
		}
	}
	
	
	
	
	
	
	
	

}

buildMap(myMap);
