Eyeofterror Minibrain

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

Overview​

EyeOfTerrorMiniBrain is a MiniBrain component that defines the behavioral logic for the Eye of Terror entity in Don't Starve Together. It uses a priority-based behavior tree to prioritize panic responses (e.g., electric fences, combat), followed by eating food and wandering to a remembered spawn point. It relies on the eater component to identify edible items and the knownlocations component to store and retrieve its spawn position.

Usage example​

local inst = CreateEntity()
inst:AddComponent("brain")
inst:AddComponent("eater")
inst:AddComponent("knownlocations")
inst:AddComponent("combat")
inst:AddComponent("locomotor")

-- Assign the mini-brain to the entity
inst.brain = EyeOfTerrorMiniBrain(inst)
inst.brain:OnStart()
inst.brain:OnInitializationComplete()

Dependencies & tags​

Components used: eater, knownlocations, combat (implicitly via ChaseAndAttack), locomotor (implicitly via behavior tree), transform (for position), physics (for world coordinates).
Tags: Checks busy (state tag), outofreach, and INLIMBO (used in FindEntity filtering).

Properties​

No public properties.

Main functions​

OnStart()​

  • Description: Initializes the behavior tree for the Eye of Terror. The root node prioritizes escaping danger (panic triggers, electric fence), then combat, then eating food, and finally wandering near the remembered spawn point—unless currently charging.
  • Parameters: None.
  • Returns: Nothing.
  • Error states: None documented.

OnInitializationComplete()​

  • Description: Records the entity’s current world position (with y = 0) as the "spawnpoint" location. This point is later used as the target for the Wander behavior.
  • Parameters: None.
  • Returns: Nothing.

EatFoodAction(inst) (local helper)​

  • Description: Constructs an Action to find and eat a nearby edible item. Fails if the entity is in a busy state, no valid food is within range (FOOD_DISTANCE = 20), or the item is unreachable or in limbo.
  • Parameters: inst (Entity) — the Eye of Terror entity instance.
  • Returns: BufferedAction instance for ACTIONS.EAT, or nil.
  • Error states: Returns nil if inst.sg:HasStateTag("busy") is true, or if FindEntity yields no valid food.

GetSpawnPoint(inst) (local helper)​

  • Description: Retrieves the previously stored "spawnpoint" location from knownlocations.
  • Parameters: inst (Entity) — passed for API consistency but unused.
  • Returns: Vector position (pos.x, pos.y, pos.z) or nil if "spawnpoint" was never recorded.

Events & listeners​

None. This component does not register or push events directly.
