I'm trying to set up a simple AI for the enemy blueprint to make them target player's chosen character which is a parent of the main character BP

I know you say to ignore it but It’s not just that you have the bottom half of your first screenshot disconnected is it? There’s nothing that I can see that defines your character base bp as the attack target within the blackboard key.

I’m following the same tutorial currently and he starts with that section connected so that the player is always the attack target. But disconnects it when creating more complex logic to determine the attack target.
