Description:
 """Retrieve all Components for a specific Entity, as a Tuple. Retrieve all Components for a specific Entity. The method is probably not appropriate to use in your Processors, but might be useful for saving state, or passing specific Components between World instances. Unlike most other methods, this returns all of the Components as a Tuple in one batch, instead of returning a Generator for iteration. Raises a KeyError if the given entity does not exist in the database. :param entity: The Entity ID to retrieve the Components for. :return: A tuple of all Component instances that have been assigned to the passed Entity ID. """
