Hello, I am working in Unity to implement a callback event for when ground plane tracking is lost since Vuforia does not have that event built into it's PlaneFinderBehaviour.cs script already.
My current method is to track when OnAutomaticHitTest() fails to fire for an Update() but correctly fired on the previous Update().
However once the OnAutomaticHitTest() is sent once from the PlaneFinderBehaviour.cs script, it will continue to fire forever, regardless of the actual tracking state. So I cannot use it to hook into this event.
PlaneFinderBehaviour.cs also does not call events from the ITrackableEventHandler.cs interface, so I cannot use that either.
Has anyone solved this?
