Do blackboard values update when the same blueprint variable updates?

I have an enum state variable for my boss character, and assign it to a blackboard key on initialization. Will updating the state variable in my boss character blueprint cause the blackboard to also be updated, or will I have to update it manually every time at the head of the behaviour tree?

This is for a multiplayer game, which might(?) matter.

I think if you want other blueprint tasks to read the same values in the behavior tree, you need to set it back. Look for “Set Value as Object” or any other types. You will also need the AIcontroller’s blackboard as the target.
