how to properly link an OrthographicCamera to a OrthogonalTiledMapRenderer

How do I properly link an OrthographicCamera to a OrthogonalTiledMapRenderer? I have tiled map i'd like render and two stages that have actors on them.. I call render.render() in my screens render method as well as stages.draw(); but every i put render.setView(camera) the screen displayed flashes or does other weird things. How do I properly attach a moveable camera to a tiled map renderer? I render the map first, do game logic and then call draw on the stages. when I call translate on the camera the tiled map zooms way out for some reason?

here is my render method

public void render(float delta) {

Gdx.gl.glClearColor(1, 0, 0, 1);
Gdx.gl.glBlendFunc(GL20.GL_SRC_ALPHA, GL20.GL_ONE_MINUS_SRC_ALPHA);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
camera.update();
renderer.render();

gameLogic();

backStage.act(); // acts are called but do nothing

frontStage.act();

frontStage.draw();
backStage.draw();

}


here is where the camera and renderer get created

public void addMap(GameMap map){

this.map=map;
maps.add(map);
renderer=new OrthogonalTiledMapRenderer(map.getTiledMap(), 1/20f);
camera= new OrthographicCamera(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
float aspect = Gdx.graphics.getWidth()/Gdx.graphics.getHeight();
camera.setToOrtho(false, 20*aspect, 20*aspect);

renderer.setView(camera);
frontStage= new Stage();
backStage=new Stage();

xSize=map.getXSize();
ySize=map.getYSize();
Gdx.input.setInputProcessor(this);

}

• I solved my problem I took someones working code to make the camera move which was 100% the same as mine made a new class tried running it . It worked!! Then I slowly added more of code testing each time until I was 100% of my previous code that did not work. The only thing I changed is I now have a new source code file (the class name is still the same though). Making a new class solved withe same code solved my problem????? Nov 21 '18 at 16:19
• You must call renderer.setView(camera); in the render method so it will call every frame Nov 23 '18 at 14:41
