问题代码：if event.key == pygame.K_RIGHT:elif event.key == pygame.K_LEFT:import sysimport pygamepygame.KEYDOWN=1026def check_events(spaceship): for event in pygame.event.get(): # print(pygame.K_RIGHT,pygame.K_LEFT,event.type,pygame.KEYDOWN) if event.type==pygame.QUIT: sys.exit() elif event.type==pygame.KEYDOWN: if event.key == pygame.K_RIGHT: spaceship.rect.centerx+=100 elif event.key == pygame.K_LEFT: spaceship.rect.centerx-=100def update_screen(ai_sett,screen,spaceship): screen.fill(ai_sett.bg_color) spaceship.blitme()import pygameimport settimport shipimport game_func as gfdef run_game(): pygame.init() ai_sett=sett.Settings() screen=pygame.display.set_mode((ai_sett.screen_width,ai_sett.screen_height)) spaceship=ship.Ship(screen) pygame.display.set_caption("Alien invasion") while True: gf.check_events(spaceship) gf.update_screen(ai_sett,screen,spaceship) pygame.display.flip()run_game()import pygameclass Ship(): def __init__(self,screen): self.screen=screen self.image=pygame.image.load("spaceship.bmp") self.rect=self.image.get_rect() self.screen_rect=screen.get_rect() self.rect.centery=self.screen_rect.centery self.rect.centerx=self.screen_rect.centerx self.rect.bottom=self.screen_rect.bottom def blitme(self): self.screen.blit(self.image,self.rect)class Settings(): def __init__(self): self.screen_width=1400 self.screen_height=800 self.bg_color=(148,214,246)报错 'Event' object has no attribute 'key'本人的疑惑：1.type，keydown,k_right等值是怎么赋值的，在我为给keydown赋值之前点一下鼠标后返回的type值是不等于keydown的2.本人认为event.key()应该是函数库里的变量来捕捉鼠标操作的，就是鼠标一点它就会返回一个值，但为何实际上我一点鼠标它就报错
