That’s a little harder to do. because it’s based on the device screen size.
This may help you. UI Coordinates

I think I mean I am trying to do the off screen image tracking maybe its not called center screen
I just want to have my image target play when target off screen.

This is what you’re looking for right?

Where your info moves from the target image to the screen if not seen.
If so you want relativeTo

There’s an example project in ZapWorks Studio that shows this behaviour in action called “Tracking Grab-and-Go”.

Info under the link from last post.

Attached is a grab and go example for Studio. A few things to look at that make this work:

  1. The states at the bottom called seen and not seen
  2. Setting your objects to be relative to Z.screen (bottom of the properties)
  3. Adding actions that call your states. you will need to use the On Seen and On Not Seen actions(select the .zpt file in your hierarchy then the Add button to see these options)
  4. Assign the “seen” and “notSeen” states to the “On Seen” and “On Not Seen” actions respectively
  5. Preview and see it in action

This gets you the grab and go feature in studio with no code. Good luck.
