Завершающий урок по созданию игры Flappy Bird для android. В этом уроке озвучим игру и добавим экран окончания игры, который будет вызываться, когда птица сталкивается с препятствиями.

Здравствуйте.
Пытаюсь расширить функционал, а именно добавить птичке “жизней”.
Соответственно нужен счетчик жизней и изменять его нужно при столкновениях со столбами.
Но в месте if (tube.collides(bird.getBounds())) этого сделать не получается – отниманием еденицы дело не заканчивается, отнимаются по 1 до 0. То есть при первом же столкновении сразу считает 321.
В каком месте можно реализовать нормальный счетчик, или общая архитектура данного приложения не подходит для такой цели?
