Question

对我来说，这是LibGDX中最奇怪的事情之一。我已经在我的游戏中使用了所有其他状态的这些确切的规格，但是在不同的名称下它们都工作得很好，除了我的ShopState，它根本没有渲染任何东西！这是我的课程代码：

public class ShopState extends State{
    private Texture bg;
    private Sprite shopLayout;
    private OrthographicCamera shopCam;
    Viewport viewport;

    public ShopState(GameStateManager gsm) {
        super(gsm);
        shopLayout = new Sprite(new Texture(Gdx.files.internal("shopLayout.png")));
        bg = new Texture("bg2.png");
        shopCam = new OrthographicCamera();
        viewport = new StretchViewport(720, 1280, shopCam);
        viewport.apply();
        shopCam.position.set(shopCam.viewportWidth / 2, shopCam.viewportHeight / 2, 0);
        shopLayout.setPosition(shopCam.viewportWidth / 2 - shopLayout.getWidth() / 2, shopCam.viewportHeight / 2 - shopLayout.getHeight() / 2);
        shopLayout.setSize(650, 1100);
    }

    @Override
    public void handleInput() {

    }

    @Override
    public void update(float dt) {
        handleInput();

    }
    @Override
    public void resize(int width, int height){
        viewport.update(width, height);
        shopCam.position.set(shopCam.viewportWidth / 2, shopCam.viewportHeight / 2, 0);
    }


    @Override
    public void render(SpriteBatch sb) {
        shopCam.update();
        sb.setProjectionMatrix(shopCam.combined);
        sb.begin();
        sb.draw(bg, 0 , 0, shopCam.viewportWidth, shopCam.viewportHeight);
        shopLayout.draw(sb);
        sb.end();

    }

    @Override
    public void dispose() {
        bg.dispose();
        shopLayout.getTexture().dispose();

    }
}

我做错了什么？一切似乎都很好，但是当我点击商店按钮时，我得到的只是黑屏！

好的，找到了一个解决方案，但我不知道为什么要修复它。我所要做的就是添加一个使用当前视口的舞台。

stage = Stage(viewport);

就是这样！由于某种原因，它现在正常工作......

Spritebatch没有绘制任何东西LibGDX
