Я встретил проблему, когда я прыгнул GameObject. Я сделал игрока и землю. Игрок работает на земле и я короткое касание, игрок будет нормальным прыжком и длинным касанием, игрок будет прыгать вверх. Но иногда игрок не прыгает, когда игрок коснулся земли. Я думал, что эта проблема связана с гравитацией или массой Игрока. Эта игра сделана на платформе Unity 2d.
