Cocos2d-JS轻量级开发

官方提供了另外一种使用cocos2d js的方式，更适合web开发者，只要引用一个js就可以了

1.下载Cocos2d-JS Lite Version(去下载>>)

下载下来的将是一个完整的HelloWorld项目

参考：

<!DOCTYPE html>
<html>
<head>
    <title>Hello Cocos2d-JS</title> 
    <script type="text/javascript" src="cocos2d-js-v3.10-lite.js" charset="UTF-8"></script>
</head>
<body>   
    <canvas id="gameCanvas" width="800" height="450"></canvas>
    <script type="text/javascript">
          window.onload = function(){
              cc.game.onStart = function(){
                  //load resources
                  cc.LoaderScene.preload(["HelloWorld.png"], function () {
                      var MyScene = cc.Scene.extend({
                          onEnter:function () {
                              this._super();
                              var size = cc.director.getWinSize();
                              var sprite = cc.Sprite.create("HelloWorld.png");
                              sprite.setPosition(size.width / 2, size.height / 2);
                              sprite.setScale(0.8);
                              this.addChild(sprite, 0);

                              var label = cc.LabelTTF.create("Hello World", "Arial", 40);
                              label.setPosition(size.width / 2, size.height / 2);
                              this.addChild(label, 1);
                          }
                      });
                      cc.director.runScene(new MyScene());
                  }, this);
              };
              cc.game.run("gameCanvas");
          };
    </script>
</body>
</html>

2.使用方法：

window.onload = function(){
    cc.game.onStart = function(){
        //...
    };
    cc.game.run("gameCanvas");
};
