您的静态游戏实例不等于在main方法中创建的实例。创建2个游戏实例，并尝试使用未初始化状态的实例 你不能这样做：
public static Game instance = new Game(name);
AppGameContainer agc = new AppGameContainer(new Game("Simple Slick Game"));
AppGameContainer agc = new AppGameContainer(instance);
当调用click方法时，它使用一个没有状态的游戏实例，因为在创建游戏实例时状态没有初始化。错误来自MainMenu。mouseClick方法？
