只是实现了最简单功能。。。

这个主要是转动数据麻烦，虽说全部手动写上去也行，实际也比代码要短，只是不太好意思，强行转动（共7个图形，最后一个转动时中心会发生偏移，耍赖了一把）

实际流程（三个状态）：

• 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
