Glommerbrain

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

Overview​

GlommerBrain is an AI brain component that implements behavior for Glommer, a follower entity in DST. It defines a behavior tree (BT) that prioritizes panic responses (e.g., electric fences or proximity-based triggers), then handles roaming, following, facing, and wandering behaviors. It relies on the follower component to identify the leader and uses follow, wander, and faceentity behavior modules to govern movement and orientation.

Usage example​

local inst = CreateEntity()
inst:AddComponent("follower")
inst:AddBrain("glommerbrain")
-- When a leader is assigned via inst.components.follower:SetLeader(target),
-- Glommer will automatically follow, wander, and respond to threats.

Dependencies & tags​

Components used: follower (via GetLeader helper), behaviour system (follow, wander, faceentity), and braincommon utilities (PanicTrigger, ElectricFencePanicTrigger, DoAction) Tags: None identified.

Properties​

No public properties.

Main functions​

GlommerBrain:OnStart()​

  • Description: Initializes the behavior tree root node. Constructs a priority-based tree that executes panic responses first, followed by custom actions (e.g., leaving the world), then movement behaviors (follow, face, wander).
  • Parameters: None.
  • Returns: Nothing.
  • Error states: Assumes all required behaviors (Follow, Wander, FaceEntity) are constructed with valid function arguments and that BrainCommon helpers return correct node types.

Events & listeners​

  • Listens to: None.
  • Pushes: None.

Notes​

  • This brain does not expose public methods beyond OnStart, as behavior is fully encapsulated in its behavior tree.
  • Distance constants (MIN_FOLLOW_DIST, MAX_FOLLOW_DIST, TARGET_FOLLOW_DIST, MAX_WANDER_DIST) are hardcoded and affect all Glommer entities globally.
