libGDX: Moving camera in Stage Viewport

Question

I developed a libGDX application on Android that uses a Stage with Viewport and Camera. I wanted to change the viewport's camera position, but nothing happens. I didn't know what can cause this problem.

If I change
stage.getViewport().getCamera().position.x or I call
stage.getViewport().getCamera().translate()
anywhere, the camera position doesn't change.

I call stage.getViewport().getCamera().update() after these methods but nothing happens.

Answer 1

This problem was that, when I updated my Viewport in my ApplicationListener's resize function:

@Override
    public void resize(final int width, final int height) {
        stage.getViewport().update(width, height, false);
    }

I set the third parameter to true and this way the camera is recentered all the time, and my calls were ineffective. To solve the problem set it to false , or remove it simply because that function has a 2 paramtered signature as well.

I share this problem because it was difficult for me to find out what's going on, and this might spare some time for others in the same situation.
