How to have AI detect collision hits from physical objects

From what I understand I think the problem is here

Then I try to reference the character blueprint in the AI controler to get the “IsStunned” bool and use that as the “Bool Value” for the blackboard bool.

First of all, is there a reason you use “Get all actors of class” instead of using “Get controlled pawn”?
Secondly, you are setting the “IsStunning” key only on begin play, shouldnt you do it every time it is updated?
