Пример RoadTile позволяет легко размещать линейные сегменты на TilemapПодробнее
См. в Словарь, например дороги или трубы, с минимальный набор спрайтовдвухмерных графических объектов. Если вы привыкли работать в 3D, спрайты — это, по сути, просто стандартные текстуры, но есть специальные приемы комбинирования текстур спрайтов и управления ими для повышения эффективности и удобства во время разработки.
