Я программирую шутер для школьного проекта. В игре вы нажимаете, и пуля летит от спрайта игрока к вашему курсору. В настоящее время я запрограммировал целевой рисунок, рисунок спрайта игрока и функцию маркера, однако я хотел бы ограничить, например, сколько раз в секунду игрок может стрелять. Это отчасти для того, чтобы избежать спам-стрельбы, которая портит производительность игры, а также делает ее более сложной, чем просто быстрый щелчок мышью везде. Я бы предположил, что я мог бы использовать команду 'pygame_clock', но я не совсем уверен, как. Ниже приведен код:
