Ai Does not Work

Hello i have a problem. I’ve created an Ai behaviour tree from this tutorial
and it does not work. Ai does not see the player and the behaviour tree has only root lighted up in yellow.
I’ve checked everything twice and i only thing i found that was different was that in the Ai_controller blueprint use blackboard is different. Please help. Im adding the screen.

Nevermind I’ve found a solution :slight_smile:
