Vuforia- Implementing ITrackableEventHandler Interface

I am trying to create a script to recognise when an particular image target is found. This will show a UI for that particular image target.

I have experience extending objects in java but I am struggling with C#.

I receive this error in the debug console.

`Vuforia.UIElf' does not implement interface member `Vuforia.ITrackableEventHandler.OnTrackableStateChanged(Vuforia.TrackableBehaviour.Status, Vuforia.TrackableBehaviour.Status)'

I am not completely sure if I am doing this correctly and if anyone could tell me where I am going wrong or post a sample script it would be much appreciated

Thanks,

 

Did you find out what the problem was?

 

This was a little while back now.

But if I remember rightly, I just duplicated the script and changed script name/ class name.

Let me know how it goes.

 

Thank you for your reply! I managed to find another to make what I want to. I was playing around with an UI yes, and refering to different scripts.
