Коллизии и оптимизация кода
Господа, тема избита, вопросы обсуждались тысячи раз здесь и даже при моём участии, но вот , снова столкнулся, снова прошу помощи и это спустя почти 1.5 года, прошу подсказок и вменяемой критики, ибо знаю о своей криворукости.
Ближе к делу.
Есть готовый код, работает, но не так, как хотелось бы - вина всему - проверка коллизий, проверка в циклах с тремя вложенными. Код прилагаю, надеюсь на помощь, есть ориентир, что должно выйти в итоге. Не поленитесь, пожалуйста - прочитайте код и предложите выход. Кода 250 строк. Коллизию проверяю попиксельно ибо реакция на отклик важна до миллиметра. Мой ориентир - http://flukedude.com/theimpossiblegame/?lang=ru/ тут флешка с игрой , кубик скачет :D У меня впрочем - то всё хорошо , но отклик на прыжок слабоват очень...
Сам Код...
