В Minecraft есть различные сущность: мобы, двери/люки/кровать/кристалл Дракона Края, частицы и т.д. Сегодня заострим внимание на мобах.
Для начала работы создадим файл EntityPig.java. Из названия уже понято, что работать будем со свиньей.

При размножении появляется детеныш
Готово. Теперь в EntityList.java прописываем моба и создаем яйцо призыва
addMapping(EntityPig.class, "Pig", 90, 15771042, 14377823);
Разбираем:
EntityPig.class - наш файл со свиньей
"Pig" - Локализическое имя моба
90 - ID моба
15771042, 14377823 - цвет яйца призыва.
Готово! Теперь наш моб может жить, размножаться и следить за игроком.
