python儿童学游戏编程知识点总结

Python  /  管理员 发布于 7年前   151

python爬虫基本告一段落，琢磨搞点其他的，正好在网上看到一个帖子，一个外国13岁小朋友用python写的下棋程序，内容详细，也有意思，拿来练手。

13岁啊。。 我这年纪还在敲 dir啥的吧

想到原先玩跑跑卡丁车时看到欧酷有个4岁熊孩子玩的完美漂移录像，深受打击，从此退出车坛。。。

废话不多说，记录一下这几天的游戏编程折腾史

游戏规则：6*6的方格棋盘，两个人轮流点击棋盘画横线或竖线，谁成功围成一个格子，这个格子算作此人的积分。

游戏架构：客户端和服务端。

先来看下游戏准备工作，需要用到pygame这个python包。

下载小朋友准备的Resource文件，游戏用到的图片、声音啥的。

一下为BoxGame（客户端）和Server代码，已添加注释。
