我的python/pygame游戏在使用pygame.key.get_pressed（）时没有响应

所以我的游戏工作正常，但精灵不会处理重复按键。我以为我修好了它，但现在一旦我通过开始屏幕，我什么也做不了。我认为问题的代码是在playgame（）下。如果有人知道这将是伟大的！我的python/pygame游戏在使用pygame.key.get_pressed（）时没有响应

      menuscreen.blit(background,(0,0)) 

      menuscreen.blit(arrow,arrowpos[counter]) 
     pygame.display.update() 




menu_screen_options()

此外，我不知道这是否会有所帮助，但代码为精灵类是。

import pygame 


class PlaneClass(pygame.sprite.Sprite): 




    # -- Methods 
    # Constructor function 
    def __init__(self,x,y,sprite_image): 
     self.image=sprite_image 

     self.x=x 
     self.y=y 
     pygame.sprite.Sprite.__init__(self) 

    def move(self,new_x,new_y): 
     screen=pygame.display.get_surface() 
     self.new_x=new_x 
     self.new_y=new_y 
     screen.blit(self.image,(new_x,new_y)) 
     pygame.display.update()
