# Blackboard Follower Any object which wants to subscribe to the **Blackboard**, which allows that object to receive `BlackboardEvent` and `BlackboardNote` notifications, needs to implement `IFollowBlackboard` or (perhaps more easily) inherit from `BlackboardFollower`. ### **Blackboard Follower** Inheriting from `BlackboardFollower` will allow your object to automatically subscribe and unsubscribe from the blackboard, and provides methods you can override for handling notifications. Check the `GameData` object in the **Party Based RPG** demo game to see how this is used. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
