Scene2d how to handle touched actor?(LibGDX)

Question

I have a problem with using scene2d in libgdx. I can\'t find anywhere a method that allows me to check wheter the actor is touched or not. I can only find methods that told

Answer 1

I had the similar problem and moreover I needed to know the current coordinates; So I resolved the issue something like this:

At first we extend the standard listener:

class MyClickListener extends ClickListener {
    float x, y = 0;

    @Override
    public boolean touchDown(InputEvent event, float x, float y, int pointer, int button) {
        this.x = x;
        this.y = y;
        return super.touchDown(event, x, y, pointer, button);
    }

    @Override
    public void touchDragged(InputEvent event, float x, float y, int pointer) {
        this.x = x;
        this.y = y;
        super.touchDragged(event, x, y, pointer);
    }
}

Then add an instance to the Actor:

class MyActor extends Actor {
    private final MyClickListener listener = new MyClickListener();
    MyActor() {
        addListener(listener);
    }
    ...
}

And in a draw (act) method use the following:

if (listener.getPressedButton() >= 0)
    System.out.println(listener.x + "; " + listener.y);

Answer 2

you can check your input simply by do this in your render method

gdx.app.log("","touched"+touchdown);

firstly set the input processor..

Gdx.input.setInputProcessor(mystage);

then you can add input listener to your actor in the create method

optone.addListener(new InputListener() {
        @Override
        public void touchUp(InputEvent event, float x, float y,
                int pointer, int button) {
                boolean touchdown=true;
            //do your stuff 
           //it will work when finger is released..

        }

        public boolean touchDown(InputEvent event, float x, float y,
               int pointer, int button) {
               boolean touchdown=false;
            //do your stuff it will work when u touched your actor
            return true;
        }

    });

You can keep track of this in your InputListener. Create a boolean field isTouched, set to true when you get a touchDown, false when you get a touchUp. I use this method in my top-down shooter and it works very well.
