Unity: Scripting and Geocaching

I started familiarising myself with the Unity interface and tutorials. I particularly found the tutorial Unity Scripting extremely helpful in implementing the Geocaching for the AR.

using UnityEngine;

using System.Collections;

public class Gps : MonoBehaviour {

 // Use this for initialization the geolocation/location based information

 IEnumerator Start () {

   // First, check if user has location service enabled

   if (!Input.location.isEnabledByUser)

   {

     // remind user to enable GPS

     // As far as I know, there is no way to forward user to GPS setting menu in Unity

   }

   // Start service before querying location

   Input.location.Start();

   // Wait until service initializes

   int maxWait = 20;

   while (Input.location.status == LocationServiceStatus.Initializing && maxWait > 0) {

     yield return new WaitForSeconds(1);

     maxWait--;

   }

   // Service didn't initialize in 20 seconds

   if (maxWait < 1) {

     print("Timed out");

   }

   // Connection has failed

   if (Input.location.status == LocationServiceStatus.Failed) {

     print("Unable to determine device location");

   }

   // Access granted and location value could be retrieved

   else

     print("Location: " + Input.location.lastData.latitude + " " + Input.location.lastData.longitude + " " +    Input.location.lastData.altitude + " " + Input.location.lastData.horizontalAccuracy + " " +  Input.location.lastData.timestamp);

  // Stop service if there is no need to query location updates continuously

  Input.location.Stop();

 }

}
