Ai Trigger

Hello. I was not sure if my post got posted? :stuck_out_tongue: I did not see it on here,so Im trying again.
To make this short, I want the player to be able to enter and leave the trigger box anytime he pleases but the AI may not.
Iā€™m not sure how to block the AI with a collision, without having the player get forced out if hes inside the trigger.
Thank you.
