[0]Laya tiledmap 监听事件未响应

    private tiledMap: Laya.TiledMap 
    /** */
    private onLost() { 
        this.tiledMap = new Laya.TiledMap(); 
        this.tiledMap.createMap("resource/tiledMap/isometric_grass_and_water.json", new Rectangle(0, 0, Laya.stage.width, Laya.stage.height), Handler.create(this, this.mapLoaded), null, new Point(1600, 800)); 
    } 
    private mapLoaded(): void {
        let _mapSprite = this.tiledMap.mapSprite();
        _mapSprite.mouseEnabled = true;
        _mapSprite.hitTestPrior = true;
        Laya.stage.focus = _mapSprite;
        let event = _mapSprite.on(Laya.Event.CLICK, this, () => {
            LogUtil.w("响应点击事件")
        })
    }
 
尝试使用focus 好像也没有响应 请问大佬们能解答一下吗
