Python逃生游戏，,从<趣学Python

从<趣学Python编程>上看到的例子，小人在石头上跑跳直到达到门

我做了以下改进：

1. 模块化：

helper.py 含有基类以及碰撞检测函数man.py 小人door,py 门stone.py 脚踩的石头game.py 主函数，初始化canvas，游戏主循环2. 修复一个Bug，原先人踩在石头上会掉下来if btm and falling and self.y == 0 \
and (co.y2 >= self.game.canvas_h \
or collide_bottom(1, co, s_co)): #man stand on the stone
falling = False
