    for image in ships_list:

    for i in range(4):
        new_ship = Ship(ships_imgs, all_active_sprites, ships)

        # draw/render

        WINDOW.blit(background, background_rect)
        all_active_sprites.draw(WINDOW)

        # done after drawing everything to the screen
        pygame.display.flip()

        #limit to 30 FPS
        FPSCLOCK.tick(FPS)

if __name__ == "__main__":
    main()

如果要选择将ships_list中的4张png图像添加到环境中，则我要为其分配唯一的运动模式。例如，ship2.png特有的锯齿形运动模式。

我不确定实现此目标的最有效方法。我是否需要用每种船的特定类别替换一般的class Ship(...):，然后在def main()中随机调用一个类别？

我来自统计学背景，因此任何您认为相关的文献都将是有益的。谢谢，身体健康！
