C#贪吃蛇游戏实现分析
转载 &更新时间：日 16:49:12 & 作者：冰封一夏
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

C#窗体贪吃蛇的游戏界面是怎么做的？就是贪吃蛇那个游戏的每个小方框是怎么做出来的？求高手
我们界面期末作业做一个作品出来，我就想做一个贪吃蛇游戏，现在才开始制作，不知道那个贪吃蛇的游戏界面是怎么制作的，求高手，谢谢啦
我有更好的答案
直接在窗体上调用GDI函数画x*y个rectangle就行了.蛇可以用不同的颜色来画.与俄罗斯方块是差不多的.

winform界面呗 .. 里面应该是Bitmap类呗 然后你再查查

　　贪吃蛇小游戏，使用C#编写的实例源码，界面窗体做的不错，同时它还具备基本的游戏设置，比如蛇体颜色设置、食物颜色设置、游戏难度设置，分菜鸟、大鸟、老鸟、自虐四个级别等。游戏操作方面：ASDW为四方向控制键，空格暂停游戏。
