SpatialEntity.MarkerText

string MarkerText{ get }

Description

The marker’s decoded string data, for QR family markers that contain text. Null if unavailable. Each read creates a new string, so cache it, and read again when HasChanged flags the Marker component.

Examples

Reading QR codes

public void StartQrCodes()
{
	Spatial.Request(SpatialCapability.QrCode);
}

public void StepQrCodes()
{
	// New lists each entity exactly once, on the frame it appears
	foreach (SpatialEntity code in SpatialEntity.NewWith(SpatialComponent.Marker))
		Log.Info($"Found a QR code: {code.MarkerText}");

	foreach (SpatialEntity code in SpatialEntity.With(SpatialComponent.Marker))
	{
		// Codes keep their last pose out of view, so only show ones in sight
		if (code.Tracked.IsActive())
			Text.Add(code.MarkerText ?? "", code.Pose.ToMatrix());
	}
}
