Крестики Нолики, реализация ООП на Java
283
21 апреля 2018, 20:23
Не могу понять, как мне сделать очередность игроков в классе Player, то есть при начале игры, я хочу чтобы первый игрок начал свой ход со второй клетки, но никак не могу понять, как это сделать, и как лучше реализовать класс Computer.
Подразумевается произвольное заполнение массива с клетки 1 по 9 переменной типа String. Как это можно сделать?
Дайте пару советов, уже битый день бьюсь над этими двумя проблемами, ничего в голову не приходит.
Ниже предоставлены коды всех имеющихся классов:

}Answer 1
Понравилась идея с Крестиками-Ноликами и решил написать свою программу (Ссори за английский. Я на нем говорю). Запускаешь Game.java и играешь. В программу вставил нубский "искусственный интеллект", который в свой первый ход ходит рандомно, а в последующие начинает "думать" как сходить. Игра заканчивается либо победой, либо заполнением всех клеток (не стал писать код для "ничьи" - лень).
НЕ ЗАБУДЬТЕ ЗАПИХНУТЬ ТРИ НИЖЕ ПРЕДСТАВЛЕННЫЕ ПРОГРАММЫ В PACKAGE С ИМЕНЕМ "homeworks"
EDIT 1: Есть ошибка в комбинации, когда создаем фигуру "треугольник" для победы. тут у меня программа просто не ходит и все.. Вариант этой фигуры:
0X0
--0--
--X--
Компьютер должен хоть как-то сходить, но не хочет. Где-то ошибка. исправьте ее, если не лень.
EDIT2: Не лень было найти ошибку. Она была в условии, при которых комп должен был выиграть. Я делал проверку на 1, когда надо было на -1.
