Question

在我的代码中，我正在使用以下代码来加载.tmx映射。我也使用IsometricTiledMapRenderer。我想在平铺上的触摸事件中添加一个单位。

assetManager.setLoader(TiledMap.class, new TmxMapLoader(new InternalFileHandleResolver()));
        assetManager.load("maps/grass_and_water.tmx", TiledMap.class);
        assetManager.finishLoading();

        map = assetManager.get("maps/grass_and_water.tmx");

        renderer = new IsometricTiledMapRenderer(map, 1f / 64f);

        Gdx.input.setInputProcessor(new GestureDetector(new MapGestureListener(camera, jetFlyingSprite, map)));`

在touchDown中，我试图在单击时添加TextureMapObject。

 @Override
public boolean touchDown(float x, float y, int pointer, int button) {
    Gdx.app.log(TAG, "touchDown gesture");
    flinging = false;
    scale = camera.zoom;
    //return false;

    Vector3 clickCoordinates = new Vector3(x,y,0);
    Vector3 position = camera.unproject(clickCoordinates);

    Texture texture = new Texture("jet_flying.png");
    TextureRegion textureRegion = new TextureRegion(texture,400,400);

    MapLayer mapLayer =  map.getLayers().get("objects");
    mapLayer.setVisible(true);

    TextureMapObject textureMapObject = new TextureMapObject(textureRegion);
    textureMapObject.setName("plane");
    textureMapObject.setX((float)position.x);
    textureMapObject.setY((float)position.y);
    mapLayer.getObjects().add(textureMapObject);

    textureMapObject.setX((float)position.x);
    textureMapObject.setY((float)position.y);

    return true;
}

运行时，我单击时什么也没发生。

有任何线索/吗？

我猜您的"objects"层是一个Object层，该实现在BatchTiledMapRenderer继承的IsometricTiledMapRenderer中留为空白。这意味着将渲染对象层。

BatchTiledMapRenderer renderMapLayer method会调用renderObject，它看起来像这样：

@Override
public void renderObject (MapObject object) {

}

您可以继承IsometricTiledMapRenderer并自己实现renderObject。
