widgets are local only so they cant be replicated, so remove the RepNotify and go back to your event system. your input was called locally anyway so thats not the issue.
id just test the slot borders individually, i cant see why they wouldnt work but that seems to be the breakdown
okay, i have. is there any actual way to do it or will i have to just mess around until like, four weeks later? is there any tutorials on how to make it multiplayer?
Widgets only exist on the client, so multiplayer is actually completely irrelevant!
if you want to display replicated data thats different however the replicated data would be on an Actor and the widget just “binds” to it
the point here is to break down where the problem could lie, and since the widget does exist and it receives the value the only problem i can see is with your border.
