Wilsonbrain

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

Overview​

Wilsonbrain is a brain component that implements Wilson's default behavior tree logic for combat and movement. It inherits from the base Brain class and defines a priority-based behavior tree where the primary action is to hold and maintain an attack target while the player holds the primary mouse button. If no such input is present (or the player controller is absent), it falls back to a standard chase-and-attack sequence. This component is responsible for orchestrating Wilson's autonomous combat behavior when no higher-priority AI task is active.

The behavior tree leverages the ChaseAndAttack behavior and uses PlayerController:IsControlPressed to detect whether the player is actively engaging in combat via the primary control.

Usage example​

local inst = World.EntityPool:GetNewEntity("wilson")
inst:AddComponent("brain")
inst.components.brain:SetBrainClass("WilsonBrain")

Dependencies & tags​

Components used:

  • playercontroller — used to query control state via IsControlPressed(CONTROL_PRIMARY).

Tags: None identified.

Properties​

No public properties are initialized in the constructor beyond those inherited from Brain.

Main functions​

WilsonBrain:OnStart()​

  • Description: Initializes and assigns the root behavior tree node for Wilson. The tree prioritizes the player-held primary control state: if the player is holding the primary button, the ChaseAndAttack behavior is continuously re-evaluated; otherwise, it falls back to a single ChaseAndAttack invocation with no time limit.
  • Parameters: None.
  • Returns: None.
  • Error states: None — assumes ChaseAndAttack and BT classes are properly loaded and the inst has a valid components.playercontroller.

Events & listeners​

None — this component does not register or fire any events directly.
