我正在编写一个选择你自己的冒险游戏，其中每个游戏状态是一个不同的屏幕类。当你点击屏幕上的相应按钮时，你会创建一个类的示例（将显示）（想想亨利火柴人游戏，但要简单得多）。我不知道如何做到这一点;这是我的第一个真实的游戏。
以下是我目前为止的两个课程：

public class MarketScreen implements Screen {
    final Heist game;
    private final Texture backgroundImage;
    private final Music backgroundMusic;
    private Stage stage;
    private Table table;
    private TextButton button1;
    private TextButton button2;
    private TextArea text;
    private OrthographicCamera camera;
    public MarketScreen(final Heist game) {
        this.game = game;
        //load images (64x64 pixels)
        backgroundImage = new Texture("background.jpeg");
        //load sound effects and music
        backgroundMusic = Gdx.audio.newMusic(Gdx.files.internal("ironLung.mp3"));
        backgroundMusic.setLooping(true);
        //create camera and spriteBatch
        camera = new OrthographicCamera();
        camera.setToOrtho(false, 800, 480);
        //stage setup
        stage = new Stage(new ScreenViewport());
        Gdx.input.setInputProcessor(stage);
        //table setup
        table = new Table();
        table.setFillParent(true);
        stage.addActor(table);
        table.pad(50);
        table.padTop(100);
        //button and text box setup
        String dialogue = "You turn around from the market stall to the sound of your name at a shout. It's your long-time friend and " +
                " fellow bounty hunter, Wesdru. There's an urgency to her mannerisms that raises your heart rate immediately, " +
                "your hand flying to your sword pommel at your hip. 'It's Lorena. Dras has her.' Keegin Dras, this lawless town's " +
                "most feared crime boss. 'What,' you intone breathlessly. 'She doesn't stoop to meddle with cowboys!' Wesdru grabs " +
                "your shoulders roughly and makes brutal eye contact. 'I don't know why. But I do know we have to go NOW. You and I " +
                "both know how cruel Dras can be.'\n\n\n\nYou only have enough time to buy one thing from the market. What do you take?";
        text = new TextArea(dialogue, Heist.skin);
        table.add(text).grow().colspan(2);
        table.row();
        button1 = new TextButton("Modded Grenade", Heist.skin);
        table.add(button1).width(200).expand();
        button2 = new TextButton("Lockpick", Heist.skin);
        table.add(button2).width(100).expand();
        button1.addListener(new ChangeListener() {
            @Override
            public void changed(ChangeEvent event, Actor actor) {
                game.hasGrenade = true;
                game.setScreen(new OutsideScreen(game));
                dispose();
            }
        });
        button2.addListener(new ChangeListener() {
            @Override
            public void changed(ChangeEvent event, Actor actor) {
                game.hasLockpick = true;
                game.setScreen(new OutsideScreen(game));
                dispose();
            }
        });
    }
    @Override
    public void show() { //called when screen is shown.
        backgroundMusic.play();
    }
    @Override
    public void render(float delta) {
        ScreenUtils.clear(1, 0, 0, 1);
        game.batch.begin();
        game.batch.draw(backgroundImage, 0, 0);
        game.batch.end();
        
        stage.draw();
    }
    @Override
    public void resize(int width, int height) {
    }
    @Override
    public void pause() {
    }
    @Override
    public void resume() {
    }
    @Override
    public void hide() {
        Gdx.input.setInputProcessor(null);
    }
    @Override
    public void dispose() {
        game.batch.dispose();
        backgroundImage.dispose();
        backgroundMusic.dispose();
        stage.dispose();
    }
}

个字符
每次我点击MarketScreen示例中的一个按钮，下一个屏幕就会崩溃。有时会持续大约15秒，然后在没有背景图像的情况下再运行几秒钟（只是在render方法中显示默认的屏幕填充）然后崩溃，但它总是崩溃。错误消息总是以

A fatal error has been detected by the Java Runtime Environment:
SIGSEGV (0xb) at pc=0x000000010d7fa85c, pid=22079, tid=23555

型
我相信它描述了一个分段错误，通常是由内存泄漏引起的。
可能是什么问题？为什么它会以不同的速度坠毁？
我最初将TextButton、Stage、Table和其他对象作为游戏属性，并简单地更改了它们在每个屏幕中的文本和排列，但我认为Stage可能是编写为特定于类的，所以我重构了每个屏幕类以创建自己的对象。游戏现在通常崩溃得更慢，但它仍然崩溃。
编辑：由于我希望屏幕能够根据跟踪游戏进度的布尔值进行调整，所以我没有提前创建所有屏幕。相反，我最终将创建按钮和创建侦听器的代码放在show（）中，并从hide（）调用dispose（）（因为hide是更改屏幕时自动调用的唯一方法），这似乎有效！
