Хорошо, так что мой вопрос заключается в том, как я могу сделать две одинаковые вещи, пока они оба имеют одни и те же атрибуты, но могут действовать независимо, например, я работаю над строителем города, когда использование нажимает кнопку для добавления масляной электростанции, электростанция будет добавлена в мир, однако есть только одна. как я мог сделать это так, чтобы игрок мог сделать бесшовное количество одного и того же здания, но все они действуют независимо, например, когда я иду добавить вторую часть того же здания, первая не будет следовать за мышью. Heres мой текущий код, чтобы помочь объяснить мой вопрос:Как я мог бы создать две вещи из java

Клонировать его и это клон. –
Object.clone(), это то, что вы просите? Реализуйте свой класс как Clonable, и выполните реализацию метода для копирования, как хотите, и здесь u go –
