Fused Shadelingbrain

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

Overview​

Fused_ShadelingBrain is the behavior tree-based AI brain for the fused shadeling entity. It orchestrates high-level decision-making by composing lower-level behaviors: ChaseAndAttack, Leash, and Wander, with specialized handling for a combat jump mechanic. The brain enforces constraints such as aggro range relative to a fixed spawn point and cooldown-based jump triggers, ensuring the enemy behaves responsively while remaining anchored to its designated zone.

Usage example​

local inst = CreateEntity()
-- ... setup combat, timer, and knownlocations components ...
inst:AddBrain("fused_shadelingbrain")
-- The brain automatically starts when the entity enters the world

Dependencies & tags​

Components used: combat, knownlocations, timer Tags: Checks state tag jumping via inst.sg:HasStateTag("jumping"); does not modify tags directly.

Main functions​

OnStart()​

  • Description: Initializes and attaches the behavior tree to the entity. The root node is a PriorityNode that evaluates behaviors in order of priority, starting with blocking while jumping, then handling combat jumps, followed by chasing/attacking, leashing, and finally wandering.
  • Parameters: None.
  • Returns: Nothing.
  • Error states: Does not return early; always constructs and assigns self.bt.

Events & listeners​

  • Listens to: None.
  • Pushes: try_jump — fired when the entity should perform a combat jump toward the target's position. Triggered by the WhileNode in the behavior tree when should_combat_jump() returns true.
