我無法在 Pygame 中獲取我的對(duì)象來改變我的代碼方向。import pygamepygame.init()width = 900height = 700background_image = pygame.image.load("board.png")background_image = pygame.transform.scale(background_image, (900, 700))virus_pic = pygame.image.load("virus.png")trojanvirus_pic = pygame.image.load("trojan_virus.png")armouredvirus_pic = pygame.image.load("armoured_virus.png")antivirus_pic = pygame.image.load("antivirus.png")trojanantivirus_pic = pygame.image.load("trojan_antivirus.png")armouredantivirus_pic = pygame.image.load("armoured_antivirus.png")screen = pygame.display.set_mode((width, height))pygame.display.set_caption("Anti Virus")#def anitvirus():def virus(x_virus,y_virus):    screen.blit(virus_pic, (x_virus, y_virus))def intro():    background_image = pygame.image.load("intro_background.png")    background_image = pygame.transform.scale(background_image, (900, 700))    logo_image = pygame.image.load("logo.png")    logo_image = pygame.transform.scale(logo_image, (600, 200))    pygame.display.update()    running = True    while running:        for event in pygame.event.get():            if event.type == pygame.QUIT:                running = False                pygame.quit()            if event.type == pygame.KEYDOWN:                if event.key == pygame.K_SPACE:                    main()        screen.blit(background_image, (0, 0))        screen.blit(logo_image, (width/2-300,100))        pygame.display.update()def main():    x_virus = 0    y_virus = 70    pygame.display.update()    running = True    while running:        for event in pygame.event.get():            if event.type == pygame.QUIT:                running = False                pygame.quit()        screen.blit(background_image, (0, 0))        if x_virus != 320:            x_virus += 1            virus(x_virus,y_virus)這是進(jìn)行游戲移動(dòng)的代碼^        pygame.display.update()intro()我不知道是否所有的 if 語句都是最有效的方法。我嘗試了不同的東西，但 if 語句似乎在大多數(shù)情況下都有效。我將不勝感激任何幫助。謝謝。
