java InputListener不适用于正交摄影机和角色

Question

我有一个带有正交摄影机的舞台，还有一个演员，他有addListener（来自Actor类）提供的InputListener setter。问题是，演员不处理输入，但如果在我的屏幕中删除正交摄影机，演员将处理输入，因此，对于正交摄影机，演员不处理输入，但如果删除正交摄影机，它会工作

有什么建议吗

我有以下代码

public class Test implements Screen {

    private Game game;
    private Stage stage;
    private MemoryActor actor;
    private AssetManager manager;
    private boolean loaded = false;
    float width, height;
    private OrthographicCamera camera;

    public Test(Game game){
        this.game = game;
        stage = new Stage();
        manager = new AssetManager();
        manager.load("img.png",Texture.class);
        manager.load("img1.png",Texture.class);
        InputMultiplexer im = new InputMultiplexer();
        im.addProcessor(stage);
        Gdx.input.setInputProcessor(im);
        height = Gdx.graphics.getHeight();
        width = Gdx.graphics.getWidth();
        camera = new OrthographicCamera(width, height);
        camera.position.set(((width / 2)), ((height / 2)), 0);
        camera.update();
        stage.setViewport(new ExtendViewport(300,300, camera));
    }

    public void createActor(){
        Texture back = manager.get("img.png", Texture.class);
        actor = new MemoryActor(manager.get("img1.png", Texture.class), back,0,0,50,50);
        actor.setInputListener(new InputListener(){
            @Override
            public boolean touchDown(InputEvent event, float x, float y, int pointer, int button) {
                System.out.println("down");
                return true;
            }

            @Override
            public void touchUp(InputEvent event, float x, float y, int pointer, int button) {
                System.out.println("up");

            }
        });
        stage.addActor(actor);
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        if (manager.update()){
            if (!loaded){
                createActor();
                loaded = true;
            }
        }
        stage.draw();
    }

    @Override
    public void resize(int width, int height) {

    }

    @Override
    public void show() {

    }

    @Override
    public void hide() {

    }

    @Override
    public void pause() {

    }

    @Override
    public void resume() {

    }

    @Override
    public void dispose() {

    }
}

和记忆因子：

public class MemoryActor extends Actor {

    ...

    public MemoryActor(){}

    public MemoryActor(Texture texture, Texture texBack, float x, float y, float width, float height){
        ...
    }


    public void setInputListener(InputListener il){
        addListener(il);
    }

    @Override
    public void draw(Batch batch, float alpha){
        ...
    }
}

仅仅将stage注册为InputProcessor是不够的。您还需要在每个帧中通过stage.act()触发Stage的事件处理

此外，当发生调整大小事件时，您需要正确地更新stage的Viewport。这可以通过stage.getViewport().update(width, height, true)实现。否则，该阶段将根据屏幕大小的错误假设处理事件，并可能使您的阶段不是您想要的方式。true很重要，因为它还将使相机在新的屏幕尺寸上居中，这对于UI来说是必要的
