The AI can hear the player and then chase.
The Player can throw a sound object - the enemy goes to the sound object and investigates, if player not seen or heard
If Player seen AI attacks
If non of the above AI Patrouls
If Player throws a sound object AI will go to sound location and investigate despite it shouldn’t since it sees / hears Player.
I will send the Blueprints for AI / AI Perception / Behaviour Tree / Blackboard / AnimBp / Animations / Character - all that will be needed is a Project with the First Person Character Template.
