这是由具有所有节拍的song1函数调用节拍的类

Keys类按键推送数字和值以及位置 .

Gamerun类设置一切 .

        self.first = True

        self.CanvasW = 1200
        self.CanvasH = 600

        self.frame.set_keyup_handler(self.Keyup)
        self.frame.set_draw_handler(self.draw)

重置所有值并且游戏重新开始 .

歌曲节拍由计时器产生，然后隐藏问题是节拍的位置在第二次重置后发生变化，我不明白为什么 .
