If both agents belong to the same alarm group, they’ll rush to the noise position.Investigation Behavior – Agents investigate intelligently when losing sight of the target.Fake Noise Support – Trigger decoy sounds (like explosions or distractions) to lure agents.Affects all groups included in the call.🛡️ Tactical AI (Advanced Behavior)Includes all core features, plus:Cover System – Finds safe zones behind obstacles based on the target’s direction.Peek-and-Hide Logic – Agent exposes and hides dynamically to simulate tactical combat.Safe Spot Grids – Automatically generates optimal cover points.Vertical Spot Support – Works on multi-level NavMesh setups.Ideal for shooter enemies that hide, peek, and attack from cover after a few seconds.🧰 Editor & UtilitiesCustom Patrol Path Editor – Design patrol routes directly in the scene view.Inspector-Integrated FOV – FOV settings now show directly in the BrainAI inspector.Visual Debug Gizmos – See FOV, attack ranges, and cover points in-scene.Clean Inspector Tools – Includes foldouts, icons, and tooltips for clarity.Static Utility Methods – Helpful gizmo and GUI functions for your own scripts.✅ RequirementsRequires Unity’s built-in AI Navigation system (NavMesh).Enable via Window > AI > Navigation or the Package Manager.💡 Integration TipsUse UnityEvents to trigger alarms, sounds, or VFX on detection.Fully compatible with custom animation setups — just use Animator parameters.Supports dynamic worlds with NavMeshObstacle and NavMeshModifier.Build stealth, shooter, or zombie-style AI by tweaking FOV, patrol, and aggression settings.Create your own AI type by extending BrainAI.
