A basic attribute interface is provided in the sample project for your reference, but you can also customize it if you wish.
To add an attribute interface, you need to add it to your HUD by searching for WBP_AttributeWidget in the panel.
Drag an attribute interface onto the canvas panel and name it (choose a name that describes the interface).
The AttributeWidget uses the default PlayerController-controlled Pawn's AttributeSystemComponent to handle display information. Feel free to change this as needed; this is just an example.
The interface will automatically populate with your attributes. You can use it as a reference to customize your logic.
