title: How to implement libgdx touchDragged?
body: <p>I'm stuck on implementing touchDragged listener using libgdx.</p>
  
  <p>Here is my code and can anyone suggest how to drag image when user touches it and than moves finger?</p>
  
  <p>I use stage and actor and I want to catch touchDragged event on actor.</p>
  
  <p>Thanks.</p>
  
  <pre><code>public void create () {
      Texture.setEnforcePotImages(false);
  
      stage = new Stage();
      Gdx.input.setInputProcessor(stage);
      // create a SpriteBatch with which to render the sprite
      batch = new SpriteBatch();
  
      // load the sprite's texture. note: usually you have more than
      // one sprite in a texture, see {@see TextureAtlas} and {@see TextureRegion}.
      texture = new Texture(Gdx.files.internal("ball3.png"));
      Skin skin = new Skin();
      skin.add("default", new Label.LabelStyle(new BitmapFont(), Color.WHITE));
      skin.add("ball", texture);
      Image sourceImage = new Image(skin, "ball");
      sourceImage.setBounds(50, 125, 100, 100);
      stage.addActor(sourceImage);
  
      // create an {@link OrthographicCamera} which is used to transform
      // touch coordinates to world coordinates.
      camera = new OrthographicCamera();
  
      // we want the camera to setup a viewport with pixels as units, with the
      // y-axis pointing upwards. The origin will be in the lower left corner
      // of the screen.
      camera.setToOrtho(false);
  }
  
  public void render () {
      Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
      stage.act(Gdx.graphics.getDeltaTime());
      stage.draw();
      Table.drawDebug(stage);
  
  
  
      // if a finger is down, set the sprite's x/y coordinate.
      if (Gdx.input.isTouched()) {
          // the unproject method takes a Vector3 in window coordinates (origin in
          // upper left corner, y-axis pointing down) and transforms it to world
          // coordinates.
          camera.unproject(spritePosition.set(Gdx.input.getX(), Gdx.input.getY(), 0));
      }
  }
