之前自己写着玩，写了一个，不完美，仅仅是实现了。代码如下
这是index.html
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<meta http-equiv="Content-Type" content="text/htmlcharset=utf-8" />
<title>New Web Project</title>
<script src="js/base.js" type="text/javascript"></script>
<script src="js/application.js" type="text/javascript"></script>
</head>
<body style="width: 100%height:800pxmargin:0text-align: center">
<div id="gameZone" style="position:relativemargin-left: automargin-right: auto"></div>
</body>
</html>
以下是html中引用的两个js文件

微信贪吃蛇代码怎么输入:首先说明一下，微信小程序是不能发布游戏的。
//获取手指按下坐标
touchStart:function(e){
startX = e.touches[0].x
startY = e.touches[0].y
},
//获取手指移动坐标
touchMove:function(e){
