Question

我正在尝试使用我自己的Pacman版本，目前正试图让窗口调整大小。我在这里读到了答案：https://reformatcode.com/code/python/pygame-how-do-i-resize-a-surface-and-keep-all-objects-within-proportionate-to-the-new-window-size。但在我的情况下它并没有帮助我。在我有2个屏幕，屏幕和假屏幕。如果我把所有东西设置为假屏幕上的blit它们出现但不更新它们（pacman不会移动）。如果我将它们设置为屏幕，它们会出现并更新，但不要调整大小。任何帮助或建议将不胜感激。顺便说一句，它仍然是一项进步的工作

我想通了，我需要搬家 screen.blit(pygame.transform.scale(fake_screen, event.dict['size']), (0, 0)) 进入clock.tick之上的核心游戏循环。我之前尝试过这个但遇到了一个关键错误，因为event.dict['size']没有事件来获取大小，所以我在for event in pygame.event.get():循环中创建了一个变量，然后将该变量传递到它所要求的位置为event.dict['size']。这是我改变的代码部分：

#main game loop
while not Fin:
    #For event is used to close the program
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.display.quit()
        if event.type == VIDEORESIZE:
            size = event.dict['size']
            screen = pygame.display.set_mode(size,RESIZABLE)


    #calls movement function
    Pacman.movement()

    #blits pacman map as background
    fake_screen.blit(PACMAN_MAP, (0, 0))

    #draws pacman
    Pacman.draw(fake_screen)
    #Spawns pellets
    SpawnPellets(pelletspawns)

    #draws screen
    screen.blit(pygame.transform.scale(fake_screen, size), (0, 0))
    pygame.display.flip()
    clock.tick(FPS)
