我正在与tkinter进行比赛，玩家必须避开酸雨。 我几乎完成了它，我只是需要一种方法在按下向上键后重新启动整个游戏。我已经制作了一个在下雨后击中玩家的功能。如果按下向上键，则该功能检查事件，并且触发重启功能，其中重启游戏的代码来自重启功能。全部在Game类中。 这是代码：

提前谢谢！

你可以juste从mainloop方法中删除while 1并使用布尔值来保持循环。当按下UP键并且播放器被雨水击中时，您可以将该布尔值切换为false。
然后你可以这样做：
while 1 :
g = Game()
g.mainloop()
你的游戏将永远循环。

您将mainloop() 写入init函数内部而不是init函数外部。如果您在tkinter窗口创建部分之外编写主循环，则init函数无法找到mainloop，这对于定义窗口创建部分和mainloop内部的所有代码至关重要。
您在self.canvas.bind_all('<KeyPress-Right>',self.right)部分之后编写了mainloop。
