c#贪吃蛇

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

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

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
