Couldn't load tmx - libgdx

Question

I'm using libgdx in my 2D platformer game project for college task. For now I'm confused with loading tiledmap in libgdx. I have a big tmx map with size of 11400x1500 pixels and 30x30 tile size. Also an image with same pixel size which I load it in image layer. I try to load it but libgdx shows nothing.
My question is how to load single big tmx map or should I divide the map into several segment/section? Because I've tried other small tmx (3000x1500). If the tmx is divided then how to load them as one stage?
public class Layarloh implements Screen{
private JumatUtama game;
private TiledMap map;
private TmxMapLoader mapLoader;
private OrthographicCamera kamera;
private OrthogonalTiledMapRenderer mapRenderer;
private Viewport viewport;
public Layarloh(JumatUtama utama) {
float l=Gdx.graphics.getWidth(),t=Gdx.graphics.getHeight();
this.game = utama;
loadstage();
kamera = new OrthographicCamera();
kamera.setToOrtho(false,l,t);
kamera.update();
viewport = new FitViewport(l/3,t/3,kamera);
}
public void loadstage(){
mapLoader = new TmxMapLoader();
map = mapLoader.load("stage/s11.tmx");
mapRenderer = new OrthogonalTiledMapRenderer(map);
}
public void stik(float dt){
if (Gdx.input.isKeyPressed(Input.Keys.ANY_KEY))
kamera.position.x +=100*dt;
}
#Override
public void render(float delta) {
stik(delta);
kamera.position.set(550,550,0);
kamera.update();
mapRenderer.setView(kamera);
mapRenderer.render();
}
#Override
public void resize(int width, int height) {
kamera.viewportWidth = viewport.getScreenWidth();
kamera.viewportHeight = viewport.getScreenHeight();
kamera.update();
}
Unitscale does nothing, the code above works on smaller size of tmx map.
EDIT
Code above isn't working, and the below is working, notice the maploader is loading different tmx file, above code trying to load 11400x1500 pixel with 30x30 tile size, while code below trying to load 3800x1500 with 30x30 tile size, but I try to use the code below to load bigger tmx, its not working,
public class Layarloh implements Screen{
private JumatUtama game;
private TiledMap map;
private TmxMapLoader mapLoader;
private OrthographicCamera kamera;
private OrthogonalTiledMapRenderer mapRenderer;
public Layarloh(JumatUtama utama) {
float l=Gdx.graphics.getWidth(),t=Gdx.graphics.getHeight();
this.game = utama;
loadstage();
kamera = new OrthographicCamera();
kamera.setToOrtho(false,l,t);
kamera.position.set(550,550,0);
kamera.update();
}
public void loadstage(){
mapLoader = new TmxMapLoader();
map = mapLoader.load("stage/segmen1.tmx");
mapRenderer = new OrthogonalTiledMapRenderer(map);
}
public void stik(float dt){
if (Gdx.input.isKeyPressed(Input.Keys.ANY_KEY))
kamera.position.x +=100*dt;
}
#Override
public void render(float delta) {
stik(delta);
kamera.update();
mapRenderer.setView(kamera);
mapRenderer.render();
}

Answer 1

Try this code and this should fix it.
#Override
public void render(float delta) {
kamera.position.set(x, y, z);
kamera.update();
mapRenderer.setView(kamera);
mapRenderer.render();
}
#Override
public void resize(int width, int height) {
kamera.viewportWidth = width;
kamera.viewportHeight = height;
kamera.update();
}
EDIT
In the original code, OP was missing kamera.update() statement. And also the resize method. That is something which causes trouble when displaying the tiled map properly as you need to update the camera at every iteration of render.
