[BUG] - Displaying a texture using the coordinates of an object layer

[BREBION-Mathis]

Hi, I'm developing a 2D game using a Tilemap built with Tiled. The Tilemap display is fine, but I would like to create water animations at two points on the map by fetching the object layer coordinates from the tmx file (my tilemap file). I manage to get the object, its co-ordinates and the size of the object, but when it comes to displaying the texture, the texture is not displayed at all, without any error message.

Reproduction steps/code

private static final int TILESET_COLS = 26, TILESET_ROWS = 15, TILE_WIDTH = 32, TILE_HEIGHT = 32;

	private AssetManager assetManager;

	private TiledMap map;

	private Texture tileSheet;

	private OrthogonalTiledMapRenderer tilemapRenderer;

	// Camera
	private OrthographicCamera camera;

	private SpriteBatch batch;
	private BitmapFont font;

	// Animation des chûtes d'eau
	private Animation<TextureRegion> waterFallAnimation;
	private List<Rectangle> waterFallRectangles = new LinkedList<Rectangle>();
	private float _waterFallStateTime = 0;

	@Override
	public void create() {
		batch = new SpriteBatch();

		assetManager = new AssetManager();
		assetManager.setLoader(TiledMap.class, new TmxMapLoader(new InternalFileHandleResolver()));
		assetManager.load("Map.tmx", TiledMap.class);
		assetManager.finishLoading();

		map = assetManager.get("Map.tmx");

		// Rendu de la map
		tilemapRenderer = new OrthogonalTiledMapRenderer(map);

		// Mettre la fenêtre en mode plein écran
		Gdx.graphics.setFullscreenMode(Gdx.graphics.getDisplayMode());

		// Mise en place de la caméra dans la scène
		camera = new OrthographicCamera();
		camera.setToOrtho(false, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
		camera.update();

		// Rendre le fenêtre redimensionnable
		Gdx.graphics.setResizable(true);

		// Chargement de l'animation des chûtes d'eau
		tileSheet = new Texture(Gdx.files.internal("Tiles/32x32.png"));

		TextureRegion[][] waterFallTmp = TextureRegion.split(tileSheet, TILE_WIDTH, TILE_HEIGHT);
		TextureRegion[] waterFallFrames = new TextureRegion[3];

		waterFallFrames[0] = waterFallTmp[10][14];
		waterFallFrames[1] = waterFallTmp[10][15];
		waterFallFrames[2] = waterFallTmp[10][16];

		waterFallAnimation = new Animation<TextureRegion>(0.150f, waterFallFrames);

		// Récupération du groupe d'object Layers
		MapGroupLayer objectsGroupLayer = (MapGroupLayer) map.getLayers().get("ObjectsLayers");

		// Récupération de l'object Layer "Waterfall"
		MapLayer waterFallLayer = objectsGroupLayer.getLayers().get("Waterfall");

		// Récupération des objets de l'object Layer "Waterfall"
		MapObjects waterFallObjects = waterFallLayer.getObjects();

		for (MapObject object : waterFallObjects) {
			RectangleMapObject rectangleMapObject = (RectangleMapObject) object;
			waterFallRectangles.add(rectangleMapObject.getRectangle());
		}
	}

	@Override
	public void render() {
		ScreenUtils.clear(0, 0, 0, 1);

		camera.setToOrtho(false, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
		camera.update();

		tilemapRenderer.setView(camera);
		tilemapRenderer.render();

		// Gestion de l'animation des chûtes d'eau
		_waterFallStateTime += Gdx.graphics.getDeltaTime();

		TextureRegion currentFrame = waterFallAnimation.getKeyFrame(_waterFallStateTime, true);

		batch.begin();

		for (Rectangle rectangle : waterFallRectangles)
			batch.draw(currentFrame, rectangle.x, rectangle.y, rectangle.width, rectangle.height);

		batch.end();
	}
