Как реализовать анимацию атаки?
09.11.2014, 14:12. Показов 3358. Ответов 1
Обычное движение персонажа не вызывает проблем, но вот анимация удара мечом оставляется желать лучшего. При нажатии клавиши атаки, в цикле должна крутиться анимация замаха и удара - 4 кадра. Они прокручиваются, да, но чтобы анимацию было видно - ее нужно показывать в этом же цикле в блоке нажатия клавиши атаки. Отсюда проблема - предыдущие кадры не исчезают, а остаются висеть и появляется "эффект матрицы", когда кто-нибудь уклоняется от пуль так быстро, что видны всего его предыдущие движения.
Показать не могу - скрин пустой получается. Помогите решить эту проблему. Как-то нужно удалять старую уже отрисованную картинку перед рисованием нового кадра атаки, но как?

Сам разобрался. Костыль, но все-таки работает. Основа в том, что решил делать полного без цикла при 1 нажатии клавиши атаки, а пошел через один кадр при нажатии и остальные - при отпускании клавиши. Работает на ура.
