Walrusbrain

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

Overview​

WalrusBrain is the behavior tree-based AI controller for walrus entities. It coordinates behaviors such as fleeing from predators (RunAway), chasing and attacking targets (ChaseAndAttack), following a leader (Follow), returning home at night (GoHomeAction), eating nearby food, wandering when idle, and orienting toward players or the leader. It integrates with components like combat, follower, leader, and homeseeker, using helper functions to query entity state and distant locations.

Usage example​

local inst = CreateEntity()
inst:AddComponent("walrusbrain")
-- The brain is automatically started by the parent stategraph on entity spawn.
-- No further manual initialization is required.

Main functions​

OnStart()​

  • Description: Initializes and assigns a behavior tree (BT) to the entity. The tree is constructed from priority-ordered behavior nodes that define when and how the walrus reacts to various stimuli (e.g., panic, fleeing, following, attacking, eating).
  • Parameters: None.
  • Returns: Nothing.
  • Error states: None documented; assumes Brain._ctor has already been called in the constructor.

Events & listeners​

  • Listens to: None documented.
  • Pushes: None documented.

Note: This brain relies entirely on behavior tree logic; it does not register or fire events directly.
