Hello-
This is probably less of a "can i" question and more of specifically "how to." My coding skills aren't that strong.
I'm trying to activate an info screen when Vuforia can't find any targets. I know how to do this per ImageTarget (via DefaultTrackableEventHandler). However, I have 5 targets in my scene which may or may not be tracked simultaneously. So I basically I need ot know when there are no targets being tracked.
I've traced this to the function getNumTrackableResults () but I can't figure out how to use it.
Any sample code or help would be appreciated, particularly specifically how to get this value inside DefaultTrackableEventHandler.cs. I'd fire my info screen when the number of Trackable Results = 0.
Thanks!
Including all of the following removed the errors I was getting:
