SLICK2D Состояние игры не зарегистрировано

У меня есть slick2d JavaGame под названием I hate Christmas. Игра не позволит мне перейти к следующему состоянию. Он говорит No game state registered with id of 1. Когда я запускаю тот же точный код в Game.java, он отлично работает. Вот мой код Game.javaSLICK2D Состояние игры не зарегистрировано

Ошибка исходит из метода MainMenu.mouseClick? – RPresle

Да, да.() –

Ваш статический экземпляр Игра не равный тому, что созданный в основном методе. Вы создаете 2 экземпляра игры и пытаетесь использовать тот, у которого нет инициализированных состояний.

Вы не можете сделать это:

public static Game instance = new Game(name);

и это:

AppGameContainer agc = new AppGameContainer(new Game("Simple Slick Game"));

ли это вместо:

AppGameContainer agc = new AppGameContainer(instance);

Когда ваш метод щелчок называется, он использует игру экземпляр без состояний, поскольку состояния не инициализируются при создании экземпляра игры.
