            pos: self.pos
            size: self.size
        Color:
            rgba: 1, 1, 1, 1
        Rectangle:
            texture: self.texture
            size: self.texture_size
            pos: int(self.center_x - self.texture_size[0] / 2.), int(self.center_y - self.texture_size[1] / 2.)
''')
