Thats it! Thank you very much!
It works fine for the viewport (viewable area) and shows the indicator to let you know where you need to go to come back to Object1.
I thought this would be way more complicated.
Update: I played around with it a bit and changed the sprite origin for the indicator object to keep it more in the viewport when moving around but the edges (I used a arrow image >) are often outside of the screen. Is there something like "Bound to Layout" behavior for the viewport to keep it always on screen or does anyone know a simple way to keep it always in sight completely?
/edit: If I add some kind of HUD at the bottom of the screen it would be great if the arrow could always stay in the "game" area above and not overlap the HUD/UI.
Maybe with collision checks to keep it above?
