Доброго времени суток.
Допустим у меня есть знакомый гейм дизайнер, который решил отправить мне карту, созданную в
программе. Отправил он мне ее
архивом .
Но у меня что-то никак не загружается карта. Экран пустой.
Вот код:
public class PlayScreen implements Screen {
private MyGdxGame game;
Texture texture;
private OrthographicCamera gameCam;
private Viewport gamePort;
private Hud hud;
private TmxMapLoader mapLoader; // for downloading tiles
private TiledMap map;
private OrthogonalTiledMapRenderer render;
private World world;
private Box2DDebugRenderer b2dr;
private Player player;
// light
private PointLight light;
private RayHandler rayHandlerh;
public PlayScreen(MyGdxGame game) {
this.game = game;
texture = new Texture("badlogic.jpg");
gameCam = new OrthographicCamera();

MyGdxGame.V_WIDTH / MyGdxGame.PPM,
MyGdxGame.V_HEIGHT / MyGdxGame.PPM, gameCam);

map = mapLoader.load("maps/videns.tmx");

gamePort.getWorldWidth() / 2,
gamePort.getWorldHeight() / 2,
2);
