Контроллер персонажа от третьего лица масштабирует вертикальную местность в игровом движке Unity ⇐ C#

[Anonymous]

Я работаю над игрой, используя Unity с контроллером персонажей от третьего лица StarterAssets, но столкнулся с проблемой, из-за которой мой персонаж может ходить, стоять и даже прыгать по вертикальным стенам. Такое поведение непреднамеренно, поскольку игроки не должны иметь возможность подниматься по вертикальным поверхностям, если они не поднимаются по лестнице.
Я хочу, чтобы персонаж не взбирался по вертикальным поверхностям, но при этом позволял ему двигаться дальше. склоны, по которым можно ходить. Единственным исключением для вертикального движения должен быть подъем по лестнице.

Я пробовал использовать SphereCast, чтобы определить, когда игрок пытается масштабироваться по вертикальной стене, но мне не удалось заставить его работать должным образом. Я новичок в Unity и, возможно, неправильно подхожу к этой проблеме. Итак, я решил начать все сначала и вернуться к настройке контроллера персонажа по умолчанию.
