Entry Source Interface - Flexible Directional Menu

BPI_FDM_EntrySourceObject (Blueprint Interface)

Every object you add to the menu must implement this interface. When you add your object to FDM, the OnEntryAdded interface function gets called.

when the entry is selected, the OnEntrySelected interface function gets called.

when the entry is unselected, the OnEntryUnselected interface function gets called

when the entry is removed from the FDM, the OnEntryRemoved interface function gets called.

and we have a function for debugging: GetEntryDebugName

and the most important interface function is Get Entry Metadata
