Question

Answer 1

you don't have to use the zoom to handle this here what i do and it works very well for me

camera = new OrthographicCamera(SCREEN_WIDTH/PPM, Config.SCREEN_HEIGHT/PPM);

// fix camera to the center of the screen
camera.position.set(Config.SCREEN_WIDTH/PPM/2f, Config.SCREEN_HEIGHT/PPM/2f, 0);

camera.update();

i put the conversion unit (PPM) to 100

hope this was helpful

Good luck

Answer 2

Don't use PPM, i know you might have seen a lot of tutorials using PPM but instead use virtual pixels or potato pixel for camera and box2d. Here read this wonderful article and this answer. For example:

OrthographicCamera camera = new OrthographicCamera(20, 11);

Here 20 is any arbitrary number for WIDTH and HEIGHT should be actually WIDTH*Gdx.graphics.getHeight()/Gdx.graphics.getWidth(). You don't need to set any zoom level, leave it to default.
