python - 同时运行 2 个 python 窗口

Question

我正在创建一个游戏应用程序，它有一个菜单窗口，然后是一个单独的游戏窗口。我正在尝试让 Tkinter 窗口充当游戏的菜单和 pygame 窗口，但是如果游戏正在运行，我无法使用菜单(甚至无法关闭它)。如果我尝试，我会收到一条 fatal error 消息:

Fatal Python error: PyEval_RestoreThread: the function must be called with the GIL held, but the GIL is released (the current Python thread state is NULL)
Python runtime state: initialized

Current thread 0x00002afc (most recent call first):
  File "c:\Users\James\Documents\6th form\comp sci\NEA- A Level\code\gametst.py", line 12 in main
  File "c:\Users\James\Documents\6th form\comp sci\NEA- A Level\code\Menu.py", line 15 in chess
  File "C:\Users\James\AppData\Local\Programs\Python\Python39\lib\tkinter\__init__.py", line 1884 in __call__
  File "C:\Users\James\AppData\Local\Programs\Python\Python39\lib\tkinter\__init__.py", line 1421 in mainloop
  File "c:\Users\James\Documents\6th form\comp sci\NEA- A Level\code\Menu.py", line 22 in <module>

这是要重现的最少代码:

菜单:

from tkinter import *
import game

WIN = Tk()
WIN.geometry("200x200")

def f():
    game.main()

button = Button(WIN, text="button", command=f)
button.pack()

WIN.mainloop()

游戏:

def main():
    import pygame
    pygame.init()

    WIN = pygame.display.set_mode((200, 200))

    run = 1
    while run:
        pygame.display.update()
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = 0
                pygame.quit()

有没有办法让我可以同时使用菜单和游戏？感谢您的帮助

另外，如果您知道将游戏导入菜单的更好方法，那会很棒，但不要过分担心

您可以在线程中运行 pygame 部分:

游戏.py

import pygame

def main():
    pygame.init()

    WIN = pygame.display.set_mode((200, 200))
    run = 1
    while run:
        pygame.display.update()
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = 0
                pygame.quit()
    print("pygame done")

def terminate():
    if pygame.get_init():
        pygame.event.post(pygame.event.Event(pygame.QUIT))

请注意，我添加了 terminate() 函数来停止 pygame 循环。

菜单.py

from tkinter import *
import game

WIN = Tk()
WIN.geometry("200x200")

def f():
    import threading
    # execute the pygame stuff in a thread
    threading.Thread(target=game.main).start()

button = Button(WIN, text="button", command=f)
button.pack()

WIN.mainloop()
game.terminate()  # terminate pygame loop
