俄罗斯方块之心（cocos2d-js+html5）
对于俄罗斯方块相信小伙伴们都不陌生，下面来介绍一下最近练手的一款小作品。
先看一下运行效果图：
就截取了两张图，有兴趣的朋友可以去微博上查阅视频版。

好了下面介绍一下代码。
首先介绍一下项目结构：
相信做过web开发的都不陌生这个结构。
index.html 此次要运行动画的主网页
index.js 动画运行的代码
cocos2d-js-v3.13.js 代码API文件
index.html 文件：
主要作用是启动画布，并且调用两个js文件。
<html>
<head>
<title>心title>
<script type="text/javascript" src="cocos2d-js-v3.13.js" charset="UTF-8">script>
head>
<body bgcolor="#00000">
<canvas id="gameCanvas" width="1500" height="720">canvas>
<script type="text/javascript" src="index.js" charset="UTF-8">script>

html>
cocos2d-js-v3.13.js文件是官网上下载的便不再多说，主要说明一下index.js文件。
index.js文件：
