AI Behavior Manager

The AI Behavior Manager (AC_AI_BehaviorManager) component is responsible for managing AI states (such as Idle, Patrolling, Random Roam, Investigating, Combat, etc.), ensuring smooth transitions between them. Additionally, the component allows for fine-tuning AI behavior through various configurable parameters.

It is added to the Soulslike Enemy (B_Soulslike_Enemy) class by default.

How It Works

• Behavior Tree Initialization

  • On Begin Play, the component checks if the AI has a valid Behavior Tree assigned.

  • If a Patrol Path is present, the AI starts in a Patrolling state immediately.

  • Otherwise, it defaults to the Idle state.

• State Management

  • The component dynamically adjusts the AI's state based on environmental triggers (e.g., detecting the player, being attacked).

  • State changes are handled through the SetState method, ensuring smooth transitions between behaviors.

• Fine-Tuning AI Behavior

  • The following parameters allow for custom AI tuning:

    • MaxChaseDistanceThreshold: Maximum distance AI will chase a target before stopping.

    • AttackDistanceThreshold: The distance at which AI will initiate an attack.

    • StrafeDistanceThreshold: Controls how far the AI must be from its target for strafing.

    • SpeedAdjustDistanceThreshold: Adjusts AI movement speed based on distance to the target.

    • MinimumStrafePointDistance: The minimum distance for strafing logic.

    • StrafeMethods: Defines how AI will strafe (e.g., directional preferences).

• Event Based Blackboard Updates

  • The component is responsible for adjusting Blackboard values to ensure the AI’s Behavior Tree reacts correctly to its state.

• Target & Patrol Tracking

  • The SetTarget() function updates AI’s current target (e.g., player or other AI).

  • The SetPatrolPath() function assigns a patrol route.
