I have a lot of dummy upgrades that I use in triggers. In-game, when observers look at the upgrade tab they see all the dummy upgrades.
Is it possible to hide them? I cannot figure out how >.<
Sorry, I can't help you.
I don't see any field or UI settings in data to exclude them.
Even if we suppose we can modify the Standard behavior of the Standard UI, we would mean to change the native code related to Observer player type.
Try to change "ScoreCount" and "ScoreValue". Maybe the UI tracks only some types. I doubt it works but well, we never know.
Otherwise, you should give up that idea.
Have a nice day.
