How to initialize a CloudSpatialAnchorSession?
  • Import AzureSpacialAnchors asset into your script.
using Microsoft.Azure.SpatialAnchors;
  • Add the CloudSpatialAnchorSession and CloudSpatialAnchor member variables into your AzureSpatialAnchorsScript class:
/// <summary>
/// Use the recognizer to detect air taps.
/// </summary>
private GestureRecognizer recognizer;
​
protected CloudSpatialAnchorSession cloudSpatialAnchorSession;
​
/// <summary>
/// The CloudSpatialAnchor that we either 1) placed and are saving or 2) just located.
/// </summary>
protected CloudSpatialAnchor currentCloudAnchor;
​
/// <summary>
/// True if we are 1) creating + saving an anchor or 2) looking for an anchor.
/// </summary>
protected bool tapExecuted = false;
  • Initialize Session:
/// <summary>
/// Initializes a new CloudSpatialAnchorSession.
/// </summary>
void InitializeSession()
{
Debug.Log("ASA Info: Initializing a CloudSpatialAnchorSession.");
​
if (string.IsNullOrEmpty(SpatialAnchorsAccountId))
{
Debug.LogError("No account id set.");
return;
}
​
if (string.IsNullOrEmpty(SpatialAnchorsAccountKey))
{
Debug.LogError("No account key set.");
return;
}
​
cloudSpatialAnchorSession = new CloudSpatialAnchorSession();
​
cloudSpatialAnchorSession.Configuration.AccountId = SpatialAnchorsAccountId.Trim();
cloudSpatialAnchorSession.Configuration.AccountKey = SpatialAnchorsAccountKey.Trim();
​
cloudSpatialAnchorSession.LogLevel = SessionLogLevel.All;
​
cloudSpatialAnchorSession.Error += CloudSpatialAnchorSession_Error;
cloudSpatialAnchorSession.OnLogDebug += CloudSpatialAnchorSession_OnLogDebug;
cloudSpatialAnchorSession.SessionUpdated += CloudSpatialAnchorSession_SessionUpdated;
​
cloudSpatialAnchorSession.Start();
​
Debug.Log("ASA Info: Session was initialized.");
}
  • Add methods to handle delegate calls.
private void CloudSpatialAnchorSession_Error(object sender, SessionErrorEventArgs args)
{
Debug.LogError("ASA Error: " + args.ErrorMessage );
}
​
private void CloudSpatialAnchorSession_OnLogDebug(object sender, OnLogDebugEventArgs args)
{
Debug.Log("ASA Log: " + args.Message);
System.Diagnostics.Debug.WriteLine("ASA Log: " + args.Message);
}
​
private void CloudSpatialAnchorSession_SessionUpdated(object sender, SessionUpdatedEventArgs args)
{
Debug.Log("ASA Log: recommendedForCreate: " + args.Status.RecommendedForCreateProgress);
recommendedForCreate = args.Status.RecommendedForCreateProgress;
}
  • Call the InitializeSession() method inside the Start() function:
// Start is called before the first frame update
void Start()
{
recognizer = new GestureRecognizer();
​
recognizer.StartCapturingGestures();
​
recognizer.SetRecognizableGestures(GestureSettings.Tap);
​
recognizer.Tapped += HandleTap;
​
InitializeSession();
}
