Raycaster не отображает текстуры по оси Y.

Сообщение Anonymous »

Я воссоздаю движок raycast 3Dsage, но не могу правильно отразить текстуры северной и южной стен вдоль оси Y. Стрелка, расположенная в левом верхнем углу текстуры, должна продолжать движение в своем направлении, но кажется, что она переворачивается на стенах, обращенных в противоположном направлении?
вот мой исходный код:
