Eyeturretbrain

Based on game build 714014 | Last updated: 2026-02-27

Overview​

This component defines the AI behavior for the Eye Turret entity. It inherits from Brain and constructs a behavior tree (BT) upon initialization. The behavior tree prioritizes two key actions: engaging in combat via StandAndAttack, and rotating to face the nearest valid target within a specified radius using FaceEntity. The component is responsible for initializing the behavior tree root node and does not define additional state management logic beyond this setup.

Dependencies & Tags​

  • Components used: None identified.
  • Tags: Checks for the notarget tag on potential targets (via target:HasTag("notarget")). Turrets ignore targets bearing this tag.

Properties​

  • self.inst | Entity | assigned by Brain base class | Reference to the Eye Turret entity instance owning this brain component.
  • self.bt | BT | nil until OnStart() is called | The behavior tree instance controlling the entity’s behavior.

Main Functions​

EyeTurretBrain:OnStart()​

  • Description: Initializes and assigns the behavior tree (self.bt) for the Eye Turret. It constructs a root priority node that sequentially evaluates and executes either StandAndAttack or FaceEntity. The priority is .25, meaning child behaviors are re-evaluated every 0.25 seconds.
  • Parameters: None.
  • Returns: nil.

Events & Listeners​

  • Listens to: None.
  • Pushes: None.

Note: GetFaceTargetFn and KeepFaceTargetFn are helper functions defined in the local scope. GetFaceTargetFn locates the nearest player within START_FACE_DIST (10 units) who lacks the notarget tag. KeepFaceTargetFn confirms that the current target remains within KEEP_FACE_DIST (15 units) and still lacks the notarget tag. These functions are passed as callbacks to the FaceEntity behavior and are not methods of the EyeTurretBrain class.
