课后作业-结对编程项目总结

Posted 2020-10-14

安装pygame

序流程分为三个部分：

1、开始界面  

2、运行游戏  

3、退出游戏 

   　　贪吃蛇游戏说明 游戏操作要尽可能的简单，界面要尽可能的美观。 编写程序实现贪吃蛇游戏，贪吃蛇游戏是一个深受

人们喜欢的游戏：一条蛇在密闭的围墙内，在围墙内随机出现一个食物，通过键盘上的四个光标键控制蛇向上下左右四个方向移

动，蛇头撞到食物，则表示食物被吃掉，这时蛇的身体长一节，同时计10分；接着又出现食物，等待被蛇吃掉，如果蛇在移动过

程中，撞到墙壁或身体交叉（蛇头撞到自己的身体）游戏结束。

我选择贪吃蛇一是因为这是我童年玩的最多的一款游戏也是相对简单的游戏，我觉得这个游戏相对于贪吃蛇方向与移动的编写，

更有意思的是游戏耐玩性，虽然我没有写出来等级的调级，但是我会在以后不断的更改游戏。为他提供精美的背景和更完美的
