Cookiecutterbrain

Based on game build 714014 | Last updated: 2026-03-03

Overview​

CookiecutterBrain is a behavior tree implementation that governs the decision-making logic for the Cookiecutter entity. It coordinates responses to threats (via RunAway), movement toward safe zones (Wander and Leash), resource consumption (EatFoodAction), and special actions like boarding boats or returning to a remembered home location. The brain relies on the knownlocations component to persist and retrieve the home position, and the burnable component to verify that wood is safe to eat.

Usage example​

local inst = CreateEntity()
inst:AddComponent("cookiecutterbrain")
-- After initialization, the brain automatically starts managing behavior
inst.components.knownlocations:RememberLocation("home", Point(inst.Transform:GetWorldPosition()), true)

  • Error states: None identified.

OnInitializationComplete()​

  • Description: Records the Cookiecutter's current position as the home location using the knownlocations component. Ensures the position is only set once (dont_overwrite = true).
