cesiumjs 代碼選中entity，vue版

      let _this = this;
      var rider = _this.viewer.entities.getById(
        "b03de0dffb724f0f8796f45eb00d51c8"
      );
      _this.viewer.flyTo(rider).then(function() {
        _this.viewer.trackedEntity = rider;
        _this.viewer.selectedEntity = _this.viewer.trackedEntity;
        // _this.viewer.clock.multiplier = 30;
        // _this.viewer.clock.shouldAnimate = false;
      });

以上代碼可以實現，通過entity id選中圖元，同時視角定位到圖元。
