libgdx: making camera follow player

So, i had this problem. Looked everywhere and couldn't find a decent tutorial, actually any info, so here it is:

In class:

OrthographicCamera camera;

in constructor:

camera = new OrthographicCamera(Width, Height);
camera.setToOrtho(false);

in render method:

camera.position.set(player.x, player.y);
camera.update();

batch.setProjectionMatrix(camera.combined);

The last line is what was missing from all those tutorials, and the single line that makes the difference.
