Очередная версия Учебного проекта, функциональной идеей которого является простая игра.

Правила игры ...

Содержание

Цель

Демонстрация свойств языка Visual Prolog и простейших приемов программирования.

Функции

  • Размер поля игры задается интерактивно;
  • Режим многократных игр (рекомендуется только для игроков - компьютерных моделей);
  • Возможность создания многих игроков, являющихся моделями, с различными стратегиями:
    • Человек (не использовать для многократных игр);
    • Компьютер 1 с примитивной стратегией (см. Релиз 1-4, не рекомендуется использовать для многократных игр);
    • Компьютер 2 с простой стратегией просмотра на K шагов вперед (см. Релиз 5);
  • Простое добавление новых игроков.

Код

  • Проверено на версии Visual Prolog 7.3 build 7302.
  • Код реорганизован для поддержки новой функциональности.

Установка

Если Вам нужен полный набор проектов серии Polyline (персональная версия), сгрузите и разархивируйте файлы архивов, пользуясь ссылками на форуме PDC ЗДЕСЬ

  • VipSpbSDK_PE_73_Examples_Polyline_1_14.zip
  • VipSpbSDK_PE_73_Tools_Polyline_1_14.zip]

в удобную для Вас директорию.

Коммерческая версия представлена в виде одного архива и может быть получена Здесь.

Оплата в любой из указанных валют. При оплате с рублевой кредитной карты валюта оплаты конвертируется в рубли по курсу банка-эмитента карты.

Директория с именем VipSpbSDK будет создана автоматически.

Если у Вас установлен VipSpbSDK, то следует открыть проект Examples\Polyline\Polyline6\Polyline6.prj

Если у Вас нет полного набора примеров из VipSpbSDK, то для помещения игры в проект необходимо:

  • Создать проект с пользовательским интерфейсом типа console
  • Построить проект
  • В построенном проекте заменить полностью код файла "main.pro" кодом, предложенным ниже.
  • Запустить вновь построение проекта. При построении проекта ответить на предложение о включении дополнительных пакетов в проект "Add All".

Запуск

Запуск приложения из среды по E или запустить исполняемое приложение из директории EXE.
