用Python制作小游戏

谁还没有玩过俄罗斯方块呢，这款单机小游戏，简单易懂，最好打发无聊时间了。

使用python除了可以爬取图片，视频，当然可以制作一些小游戏了。

其实这个很简单，就是转化数据很麻烦 ☹

实际流程：

新生成图形块，如果从下往上已经堆到这里了（图形块出现位置出现不为空白的背景）游戏结束
下落（途中可以键盘操作块的移动，转动）
到底，图形数据记录到map，检查是否消去一行

所有的检查，就用check_action(位置x,位置y,图形块号,图形转动角度)：检查是否出界或遇到原先的块，

游戏是否结束判断：新生成图形块位置是否check_action == False
下落是否到底：y+1位置是否check_action == False
操作动作（x-1,x+1,y+1,角度+1）：是否check_action == False
