- Implemented HurtBoxOwnerGuard to ensure that multiple HurtBoxes on the same character do not register damage multiple times during a single HitBox activation. - Added custom editor for HitBox to facilitate the creation of shape colliders with HitBoxColliderProxy. - Introduced PhysicsPerceptionSystem for enemy perception, supporting multiple detection modes including RangeCircle, BatchLOS, FanCast, and BoxCast. - Created EnemyPatrolZone to define patrol and chase areas for enemies, allowing for shared zones among multiple enemies. - Added BD_IsOutsideZone conditional task for Behavior Designer to check if an enemy or player is outside a defined patrol zone.
