С# SFML OpenGl Проблема с несколькими текстурами

Редактировать: Хорошо, этот код по-прежнему не позволяет мне использовать две разные текстуры в программе. Он действует так, как будто он должен работать, но когда я говорю ему использовать первую текстуру, она такая же, как и вторая текстура, которая является последней загруженной текстурой.
