At Episode 5 ( UMG UI Inventory: Menu Functionality | 05 | v4.8 Tutorial Series | Unreal Engine - YouTube ) of the series in the 18:45 time section Could someone explain to me Why do we have to bind all the buttons with the refresh script?
It’s a method of communication, the objects you work with need to know about one another. Using a dispatcher is an elegant solution in this case, allowing the buttons to send data back to the HUD.
Thank you for the clarification, it definitely helped
