The UI_Widget is created In the FirstPersonChar.
Calling the interface is done by a Blueprint Actor in the GameWorld upon being tag by the player.
I was able to get the Object in the GameWorld tag by the player
I am not able to get that Object Blueprint the reference it need to update the UI_Widget
I guess I could try to move the logic of calling the UI_Widget on the FirstPersonChar, but I kind of find it more rational to have the different GameWorld Actors to do that.
What if their state change (Actors)
(The variable value update to the UI_Widget need to be differents at this point
(Destroyed damaged overheat plenty more),
wouldn’t it be more convenient to have them update the Ui_Widget (I might be very wrong here 
)
Is it just more efficient to do it on the player?
Is their no other way around ?
Thank for the screenshot, It is quite clear !
