Я делаю маленький клон FlappyBird и все работает как надо, пока я не изменил физическое тело птицы, чтобы оно было точным в соответствии с текстурой.Теперь, когда он летит через щель в трубах, он считает 30 очков вместо 1.
Это происходит только тогда, когда я использую текстуру с точным физическим телом, которое мне нужно, потому что птица некруглый или прямоугольный.
Как бы я сделал столкновение, чтобы оно сталкивалось только один раз с каждым узлом разрыва.Я попытался установить для categoryBitBask значение 0 после контакта, но затем все пропуски больше не добавляются к счету очков.
