Hello,

I am trying to use a for/loop iteration to get all visible markers location in locationChanged function. I want to add in locationChanged function a system to detect if user is in the same location with the marker then marker hide. If user walk away from the marker's location then the marker should be visible again.

I think that i need something like that

for (var i = 0; i < World.markerList.length; i++) {

var location = new AR.GeoObject(World.markerList.[i].markerObject.latitude, World.markerList.[i].markerObject.longitude); <- I am confused here

if (Math.round(location.distanceToUser()) <= 5) {

marker.enabled = false;

} else {

marker.enabled = true;

}

I don't know how to set location var with each markers longitude / latitude.

Can you provide me any help? Thank you very much for your time.

Is something like that possible with alternative way? I am afraid that with my way it will cause freezes or crashes because it will use for/loop all the time.

My sdk: Javascript/android

Platform: android studio

Hello,

i use the following OnLocationCahnged function, but it has no effect on the marker.

Any suggestions?

    /* Location updates, fired every time you call architectView.setLocation() in native environment. */
    locationChanged: function locationChangedFn(lat, lon, alt, acc) {
        /* Request data if not already present. */

  var userLocation = new AR.GeoLocation(lat, lon);

  var userDistanceMetersToHidePoi = 1000;


         if (!World.initiallyLoadedData) {

             World.requestDataFromLocal(lat, lon);

             World.initiallyLoadedData = true;

         } else if (World.locationUpdateCounter === 0) {
             /*
                 Update placemark distance information frequently, you max also update distances only every 10m with
                 some more effort.
              */
             World.updateDistanceToUserValues();

         }

         /* Helper used to update placemark information every now and then (e.g. every 10 location upadtes fired). */
         World.locationUpdateCounter =
             (++World.locationUpdateCounter % World.updatePlacemarkDistancesEveryXLocationUpdates);
             
             
for (var i = 0; i < World.markerList.length; i++) {

  World.markerList[i].enabled = World.markerList[i].locations[0].distanceTo(userLocation) <= userDistanceMetersToHidePoi;

  // which is equivalent to
}

  userLocation.detroy();
    },
