python pygame - 如何创建包含多个图像的拖放？

Question

所以我一直在尝试使用 python.The 中的 pygame 创建一个拼图游戏，唯一的问题是我在创建包含多个图像的棋盘时遇到了问题，我可以在屏幕上拖动这些图像（无需像拼图一样连接图像，只需简单的拖放即可）。我正在从计算机上的本地文件夹加载图像。有人可以帮我吗？

这是我迄今为止尝试过的方法，但是图像从相同的位置开始并且 pygame 将它们全部识别为一张图像

def dragdrop(path):
    dirs = os.listdir(path)
    def load_image(name, colorkey=None):
        fullname=os.path.join("data", name)
        try:
            image=pygame.image.load(fullname)
        except pygame.error, message:
            print "Impossible de charger l'image:",name
            raise SystemExit, message
        image = image.convert()
        if colorkey is not None:
            if colorkey is -1:
                colorkey = image.get_at((0, 0))
            image.set_colorkey(colorkey, RLEACCEL)
        return image, image.get_rect()

    main()

您将位置传递给精灵并将其存储在 self.pos 中，但是要绘制 Sprite 精灵组使用 rect 属性：

来自pygame.sprite.Group.draw()：

Draws the contained Sprites to the Surface argument. This uses the Sprite.image attribute for the source surface, and Sprite.rect for the position.
