私はJavaゲームのビデオチュートリアルに従っています（そこから離れることができます）が、ボタンの1つ（終了ボタン）が機能しません。助けてください。lwjgl と slick を使用しています。
メインクラス:
package javagame;
import org.newdawn.slick.*;
import org.newdawn.slick.state.*;
public class Game extends StateBasedGame {
public static final String gamename = "Java Game Alpha 1.0";
public static final int menu = 0;
public static final int play = 1;
public Game(String gamename) {
super(gamename);
this.addState(new Menu(menu));
this.addState(new Play(play));
}
public void initStatesList(GameContainer gc) throws SlickException{
this.getState(menu).init(gc, this);
this.getState(play).init(gc, this);
this.enterState(menu);
}
public static void main(String[] args) {
AppGameContainer appgc;
try{
appgc = new AppGameContainer(new Game(gamename));
appgc.setDisplayMode(1600, 800, false);
appgc.start();
}catch(SlickException e) {
e.printStackTrace();
}
}
}

もう1つのクラスがありますが、それは問題ではありません。助けてください！
