How to send a float through an interface from PlayerState to a UMG.userwidget blueprint ?

Before calling your Interface function, try connecting the “MainUIHudRef” variable to a Print String and see if it outputs anything.

First of, thank you for your help !

Indeed it seems like it input “None”.
Why is that ? I don’t understand.

How can I fix that ?
