Leifbrain

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

Overview​

Leifbrain is the AI brain component for Leif, implementing decision-making logic using a behavior tree (BT). It defines the order of behavior priorities via a PriorityNode containing AttackWall, ChaseAndAttack, and Wander actions. This brain is responsible for executing high-priority combat or environmental interaction behaviors before falling back to idle wandering.

Usage example​

local inst = CreateEntity()
inst:AddComponent("leifbrain")
-- The brain automatically initializes its behavior tree on `OnStart()`
-- No manual initialization required after adding the component.
