I implemented ParallaxScrolling for my SideScroller project, everything is working but the tiled map (the most important part!). I've been trying out everything but it doesn't work (see the code below).

I'm using ParallaxCamera from GdxTests, it's working perfectly for the background layers.

I can't explain myself properly in english, so I recorded 2 videos:

Before parallaxScrolling

After parallaxScrolling

As you can see, now the platforms appear in the middle of the Y-axis.

I've got a Map class with 2 tiled maps, so I need two renderers too:

private TiledMapRenderer renderer1;
private TiledMapRenderer renderer2;



public void update(GameCamera camera) {
renderer1.setView(camera.calculateParallaxMatrix(1f, 0f), camera.position.x - camera.viewportWidth / 2, 
           **camera.position.y - camera.viewportHeight/2**, camera.viewportWidth, camera.viewportHeight);
renderer2.setView(camera.calculateParallaxMatrix(1f, 0f), camera.position.x - camera.viewportWidth / 2,
           **camera.position.y - camera.viewportHeight/2**, camera.viewportWidth, camera.viewportHeight);
}

In bold, the code I think I should change. I've tried changing parameters, even adding hardcoded values, etc, but one of two: 1. Nothing happens. 2. Platforms disappear.

Here is some aditional code. The render method:

     world.update(delta);
    parallaxBackground.update(camera);

    clear(0.5f, 0.7f, 1.0f, 1);

    batch.setProjectionMatrix(camera.calculateParallaxMatrix(0, 0));
    batch.disableBlending();
    batch.begin();
    batch.draw(background, -(int)background.getRegionWidth()/2, -(int)background.getRegionHeight()/2);
    batch.end();
    batch.enableBlending();

    parallaxBackground.draw(batch, camera);
    renderer.render(batch);
