这篇文章主要为大家分析了c#贪吃蛇游戏的实现代码，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
今天无聊突发奇想做个贪吃蛇，虽然网上很多这东西了，不过自己写的感觉还行吧
贪吃蛇分析
游戏规则：
1、蛇起始长度5，每吃一个食物增加1，最大15过关
2、蛇用蓝色表示，食物用绿色，障碍物用黑色
3、当蛇碰到自己、墙壁、障碍物则游戏失败
4、方向键控制蛇的移动方向，蛇不可反方向移动，如正在向上移动，不能马上向下，只能向左、右、上运动
5、每过关一次速度提升一次
大概思路：
1、地图用网格的形式表示，蛇由方格组成，保存在list中
2、1中提到了方格，方格保存的内容有，颜色，坐标，是否可以通过,是否是食物
3、向前移动一次，将前面方格添加进蛇列表中，将列表最后一个移除，若为前方格子为食物，则不移除最后一个
4、使用while死循环来做整个移动
5、空格键为加速键，通过修改while循环sleep时间来实现加速
包括了3个类一个主窗体，分别是node（用来表示方格）、map（用来表示地图）、serpent（用来表示蛇），另外一个主窗体。下面依次把代码贴上，基本上每个方法都有注释
