The system provides a basic property interface for your reference. Of course, you can also customize it, it's up to you.
To add an attribute interface, you need to add it to your HUD by searching for WBP_AttributeWidget in the panel.
Drag the property interface onto the canvas panel and name it (choose a name that describes the property interface).
AttributeWidget uses the AttribtueSystemComponent of Pawn controlled by the default PlayerController to handle display information. You can change it as needed. This is just an example.
The interface will automatically fill in the attributes you have. You can refer to it for specific logic to customize yours.
