Eyeofterror Mini

Based on game build 714014 | Last updated: 2026-03-05

Overview​

The eyeofterror_mini prefab defines the behavior and properties of the mini Eye of Terror creature, a flying, hostile enemy. It integrates multiple components to handle health, combat, locomotion, diet, and behavior. The prefab sets up an entity with a custom brain (eyeofterror_minibrain), state graph (SGeyeofterror_mini), and specialized AI logic for target acquisition, attack tracking, and aggression response. It is typically used as a minion or preliminary threat in larger Eye of Terror encounters.

Usage example​

local inst = CreateEntity()
inst.entity:AddTransform()
inst.entity:AddAnimState()
inst.entity:AddSoundEmitter()
inst:AddTag("eyeofterror")
inst:AddTag("flying")
inst:AddTag("hostile")
inst:AddComponent("health")
inst.components.health:SetMaxHealth(TUNING.EYEOFTERROR_MINI_HEALTH)

inst.components.combat:SetDefaultDamage(TUNING.EYEOFTERROR_MINI_DAMAGE)
inst.components.combat:SetRange(TUNING.EYEOFTERROR_MINI_ATTACK_RANGE, TUNING.EYEOFTERROR_MINI_HIT_RANGE)
inst:SetBrain(require("brains/eyeofterror_minibrain"))

Main functions​

FocusTarget(inst, target)​

  • Description: Assigns a specific target as the entity’s focus, adds the notaunt tag (indicating it should not be automatically retargeted), and instructs the combat component to engage the target.
  • Parameters:
    target (entity or nil) – the entity to set as the current target.
  • Returns: Nothing.

CheckFocusTarget(inst)​

  • Description: Validates the currently assigned focus target (inst._focustarget). If the target is invalid (e.g., dead, ghost, non-existent), it resets inst._focustarget to nil and removes the notaunt tag.
  • Parameters: None.
  • Returns: (entity or nil) – the valid focus target, or nil if none.
  • Error states: Returns nil if the focus target has died, become a ghost, or been removed.

Retarget(inst)​

  • Description: Determines the next valid target. If a valid focus target exists, returns it; otherwise, searches for a new target within a 12-tile radius using FindEntity.
  • Parameters: None.
  • Returns: (entity or nil, boolean) – the chosen target and whether it differs from the current target.
  • Error states: May return nil if no suitable target is found.

KeepTarget(inst, target)​

  • Description: Determines whether the combat component should retain the current target. Maintains focus target priority; otherwise, checks if the target remains within a 30-tile radius and is valid.
  • Parameters:
    target (entity) – the target to evaluate for retention.
  • Returns: boolean – true if the target should be kept, false otherwise.

OnAttacked(inst, data)​

  • Description: Reacts when the entity is attacked. If there is no current focus target and the attacker is not another Eye of Terror, sets the attacker as the new target.
  • Parameters:
    data (table) – event data containing attacker (the entity that attacked).
  • Returns: Nothing.

Events & listeners​

  • Listens to: attacked – triggers OnAttacked to respond to incoming damage and potentially switch targets.
  • Pushes: None identified.
