Returns a new instance of Sprite.

Parameters:

  • layer (String) (defaults to: Layer::Background) —

    the layer the object appears on.

  • origin (String) (defaults to: Origin::Center) —

    where on the image should osu! consider that image’s origin (coordinate) to be.

  • file_path (String) —
