to change DefaultTrackableEventHandler.cs,

By lamana on Mon, 12/30/2019 - 06:35

Hi, I changed the  DefaultTrackableEventHandler.cs,   adding to protected virtual void OnTrackingFound() and protected virtual void OnTrackingLost() events for videoPlayer. And it works. But when I close the project and open it next time  DefaultTrackableEventHandler.cs, returns to its previous version. How can I made changes permanent?

Subclass DefaultTrackableEventHandler and override.  Something like below.
