From google translate:
Hopefully someone can help you out.
What EVRTOP said is how to make click on second(ary) level of UMG menu item to communicate/manipulate level objects through level blueprint.
Google translate is not far off, as it is tuned for Simplified Chinese.
Well, time to play some UMG, as I’m not familiar with it, and seem to be the thing to learn for future menu/HUD?
Thank you very much!
Thank you for your answer!
