（Pygame）.blit将不会显示虽然功能

Question

所以我想创建一个计时器，当游戏运行时，游戏运行的秒数将显示在我的pygame窗口中。但由于某种原因，它似乎并不奏效。我不太确定这个问题到底是什么。 35-44

行是定时器功能是... 71 行是时间预计将显示...

    SCREEN.blit(background, (0, 0)) 
    SCREEN.blit(blacksmith,(blacksmith_position)) 
    SCREEN.blit(display_time, (70,10)) 
    pygame.display.update() 
    fpsClock.tick(FPS) 

pygame.quit()

您运行while get_time == True:其停止一切。它一直在运行。

您可以只有一个while循环，它始终运行（无限循环） - mainloop。
