That's a very simple example (only 3kb)of my issue.
500x500 window, with an object placed at 250,250. I'm on a 16x9 ratio monitor, and in full screen (scaled) the object that should be at the center of the screen is way off to the left, even when I add the scroll to behavior.
I looked at the relevant tutorial, but the Anchor behavior doesn't work as I assumed it would. It says "relative to screen size" in the description of what it does, but I thought that meant that if the screen size increased, so would the distance between the object and the thing it's anchored to, but it doesn't seem to work like that, and it doesn't help for centering an object.
The next thing I tried was anchoring it to both top left and bottom right, as if both distances were kept relative, that would (I think) result in it being centered, but it just made the object have a fit (don't know how else to describe it).
Any help in working out what I'm doing wrong would be greatly appreciated.
Edit: I should also add that in the initial instance where I came across this problem, the layout is bigger than my screen, and I still experience the same issue. I can see why my small scale example might not make that clear, sorry for any confusion.
2nd Edit: I've just realized when I was trying with the larger layout, I hadn't removed the anchor before removing the scroll to. It now works. This means a workaround is to have an object in the center with scroll to, and anything else that needs to be positioned relative to the center of the screen can be pinned to that object.
I'd still like to know if there is a better solution.
