The Zombie AI Behavior System is designed to imitate the behavior of a player-controlled Zombie. The system is primarily controlled by the BT_Zombie Behavior Tree, supported by the BB_Zombie Blackboard asset and the BP_ZombieController AIController.

AI Behavior Overview

Round Management

• The system ensures the AI behavior does not execute if the round is not in progress.

Player Detection

• When the player is in sight, the AI will actively follow the player.
• In the event of losing sight of the player, the AI will investigate the player's last known location.

Noise Detection

• Upon hearing a noise, the AI will investigate the noise location. Since the AI noise tracking is too accurate compared to a player-controlled Zombie, a feature was added to reduce the accuracy of the noise tracking, especially for noises farther away from the AI.

Hiding Spot Detection

• If the AI detects one or more hiding spots, the AI investigates all detected hiding spots.

Patrolling

• In scenarios where no other branches are executable, the AI enters a patrolling behavior. It moves to a random navigable location within a set radius.

User Stories

• As a player, I want AI zombies if I don’t have enough friends to fill the void
