这是我收到的错误：

推荐答案

问题仅在游戏正在运行(鸟是活的)并且您试图杀死游戏时才会出现。

当您按kill it时，它会运行turtle.bye()，这将删除所有对象并移除窗口，但它不会停止仍要运行move()并绘制对象的ontimer()(但它们不再存在，这会给出消息invalid command name "1771926755840move")。

当您按kill it时，它应该设置变量ie。running = False

def stop():
    global running    
    
    running = False

应签入move以停止循环并关闭窗口

    if running:
        # repeate loop and run `move` again
        turtle.ontimer(move, 50)
    else:
        # stop loop and close window
        turtle.bye()
        #winsound.PlaySound(None, winsound.SND_PURGE)

我的减少了模块的版本。

我创建了自己的类vector，所以我不需要freegames，因为我不知道。

我使用datetime而不是timeit是因为end-start可以直接提供timedelta。

我注释了winsound，因为它只适用于Windows，但我使用的是Linux。

我为paused、unpased添加了代码，它不需要Threading。

start_button.pack(fill='both')
end_button.pack(fill='both')
pause_button.pack(fill='both')

root.mainloop()

坦率地说，如果您使用tkinter to display buttons then you could use tkinter.Canvasto draw objects, andtkinter.bind()to runtap, and root.after()instead ofontimer()to run loop - and then you don't needturtle`
