реализовать игровые состояния с макетом MVC?

Привет, я создаю базовую игру и пытаюсь реализовать шаблон MVC с помощью своего кода. В настоящее время у меня есть: Модель игровой объект, облака, вода в лодке и т. д.

мир Это связывает все модели вместе и определяет объекты

WorldRenderer Применяет все текстуры к объектам.

GameScreen обрабатывает пользовательский ввод, касание или клавиатуру.

Моя проблема в том, как и где я могу реализовать игровые состояния? Я предполагаю, что он попадет на GameScreen, но я реализовал базовую схему состояний, READY, RUNNING, PAUSED, NEXT_LVL, GAME_OVER,

Но что я обнаружил, когда при представлении состояния READY игра работает в фоновом режиме?

это определено в WorldRenderer, то есть уровень воды поднимается вверх по экрану на заднем плане, но я хочу, чтобы это происходило только тогда, когда состояние игры переключается на бег.

как мне заставить Gamestate инициализировать WorldRenderer только тогда, когда Gamstate переключается в РАБОЧЕЕ СОСТОЯНИЕ. Я применил оператор renderer.render(); к оператору RUNNING, но он все еще работает в состоянии READY.

Любая помощь в этом будет очень признательна.

Ваше здоровье

Даниэль.

Я присоединяю классы WorldRenderer, World и GameScreen.
