There is an error flying to entity in the event of waiting for the map to be loaded.

This is my code.

    const helper = new Cesium.EventHelper()
    helper.add(viewer.scene.globe.tileLoadProgressEvent, (e) => {

      if (e === 0) {

        helper.removeAll()

        const entity = viewer.entities.add({
          position: Cesium.Cartesian3.fromDegrees(117, 30, 39),
          point: {
            color: Cesium.Color.RED,
            size: 6
          }
        })

        viewer.flyTo(entity)

      }
    })

Entity has been added to entities. Why is the array here empty

Replace this line with:

setTimeout(()=>{
  viewer.flyTo(entity);
},10);

Sometimes we invoke some task before completing the render process. Iā€™m not sure if it will work, but you can try this approach.

This means that the map does not start rendering after loading. Can I manually call the rendering function before the flyto method? Of course, using setimeout can solve this problem :thinking:

Yes you can call viewer.scene.requestRender();
