Normally, tile-based levels are stored in two-dimensional arrays, and Cocosban follows this trend. So, the first global variable we'll declare in gamescript.js, which is an array containing level data, is as follows:

var level = [
  [1,1,1,1,1,1,1],
  [1,1,0,0,0,0,1],
  [1,1,3,0,2,0,1],
  [1,0,0,4,0,0,1],
  [1,0,3,1,2,0,1],
  [1,0,0,1,1,1,1],
  [1,1,1,1,1,1,1]
];

Each item represents a tile, and each value represents an item, which I coded this way:

Our gameScene declaration is always the same:

var gameScene = cc.Scene.extend({
  onEnter:function () {
  this._super();
    gameLayer = new game();
    gameLayer.init();
    this.addChild(gameLayer);
  }
});

And finally, we are ready to extend the game...
