Is it possible to create a Custom Geocoder and provide a custom 'complete' function?

CesiumJS

Whether you are using a custom geocoder or not, there is a complete event you can subscribe to. Here’s a simple example that does exactly what you want:

var viewer = new Cesium.Viewer(‘cesiumContainer’);

var lastGeocode = viewer.entities.add({

point: {

pixelSize: 20,

heightReference : Cesium.HeightReference.CLAMP_TO_GROUND

}

});

var removeListener = viewer.geocoder.viewModel.complete.addEventListener(function(){

lastGeocode.position = viewer.scene.camera.positionWC;

});

Do you simply mean, do a flyTo, then add a polygon? FlyTo has the ‘complete’ callback function, so just add it after (with a timeout to remove, or some other cleanup);

viewer.camera.flyTo({
    destination : Cesium.Cartesian3.fromDegrees(-117.16, 32.71, 15000.0),
    complete: function () {
        // add your highlight here at the end of the journey
        var highlight = viewer.entities.add({...});
        setTimeout ( () => { viewer.entities.remove(highlight); }, 4000 );
    }
});

Add a fancy opacity fader (quick in, slow out) for dramatic effect. :slight_smile:
