Than you for responding.
This is the code:
The first shows the script in Player Character Blueprint. I tried to follow how Fallout games do it. You press tab to open the menu but pressing it again will close it. This way any open menu can be closed with tab.
The widget itself looks like this (the buttons at the top switch between widgets and the one in the bottom closes the window):
This is the code I put in an actor that manages level data (Time of day, and bunch of other settings). Such actos is present in each level that is being streamed to the persistent level. The persistent level does not have such actor.
I also tried to put identical code into Level Blueprint.
Any help would be appreciated. Thanks.
