Python pygame -如何创建多个图像的拖放

Question

所以我一直在尝试使用python中的pygame创建一个拼图游戏。唯一的问题是，我在创建带有多个图像的面板时遇到了麻烦，我可以在屏幕上拖动这些图像(不需要像拼图一样连接图像，所以只是简单的拖放)。我正在从电脑的本地文件夹中加载图像。有人能帮帮我吗?

这就是我到目前为止所尝试的，但是图像从相同的位置开始，pygame将它们都识别为一个图像

    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()
    class Ichrom(pygame.sprite.Sprite):

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

From pygame.sprite.Group.draw():

将包含的精灵绘制到Surface参数。这使用雪碧。image属性用于源表面，以及Sprite。Rect for position.
