Я хотел бы знать, что я делаю не так с обнаружением столкновений.Я пытаюсь создать игру, в которой пользователь управляет персонажем с помощью виртуального джойстика и пытается поймать пончики, падающие с верхней части экрана.Джойстик работает и работает с выпадением пончика, но когда два объекта сталкиваются, счет не обновляется, и местоположение пончика не сбрасывается в положение по умолчанию, как я хочу.Я просмотрел несколько уроков, но, похоже, не могу найти свою ошибку.
