Python/Pygame使用类/函数创建启动屏幕

Question

我正在尝试在我的游戏开始时创建一个屏幕，当我按任意键时，它将激活我的游戏循环。我已经获得了大约80％的屏幕上的工作，我无法得到它的最后一个。我只是试图在我通过启动屏幕的地方，第一个级别将启动。任何帮助/输入非常感谢。谢谢。关注的主要区域在Player课中被3个星号包围。该方法wait和level

你必须写一个函数：

def intro(): 
    smallfont = pygame.font.SysFont(None, 30) 
    while intro == True: 
     for event in pygame.event.get(): 
      if event.type == pygame.QUIT: 
       pygame.quit() 
       quit() 
      elif event.type == pygame.KEYDOWN: 
       intro = False 
     gameDisplay.fill(white) 
     text = smallfont.render("press any key to continue",True , (0, 0, 0)) 
     gameDisplay.blit(text, [320,240]) 
     pygame.display.update() 
     clock.tick(15) 
intro() 
main()
