Таким образом, проблема сейчас, когда кнопка Randomize нажата или большое количество ячеек существует, а затем таймер запускается, клетки не так быстро, как они будут с менее активными клетками , Например, при 100 столбцах и 50 строках, когда нажата кнопка рандомизации, активируется одна ячейка, затем следующая, затем другая и так далее. Могу ли я активировать их в одно и то же время? Это просто проблема со слишком многими вещами, рассчитанными сразу? Помогло ли совмещение?
QUICK EDIT: Является ли таймер качания лучшей идеей для этого проекта?
У вас * действительно * надеюсь, что кто-то будет читать через весь этот код? –
Не совсем, но на всякий случай кто-то хотел задать вопрос об этом, тогда он был легко доступен. – mistapaluza
