Я работал над этим проектом о танках (основанном на игре Tank Trouble), и я нашел 2 ошибки в моей игре.
Первое, когда я порождаю пулю, которая стреляет сама по себе без какого-либо ключевого ввода. Второй - пули, выпущенные прямо из башни, когда угол наклона танка равен 0 ° или 180 °.
Я хочу исправить их, но не могу найти проблему. Я буду признателен за любую помощь!
Вот мой танк и пуля:
Здесь такое код игры:
