Antlionbrain

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

Overview​

AntlionBrain implements the AI for the antlion boss entity using a behavior tree (BT). It coordinates high-priority rock-eating during health recovery, standard combat via StandAndAttack, and a post-fight calm phase where attack speed is reduced before resuming normal aggression. It relies on the health, combat, and worldsettingstimer components to make state-aware decisions.

Usage example​

local inst = CreateEntity()
inst:AddComponent("antlionbrain")
-- The brain is automatically initialized when added
-- It will evaluate behaviors and trigger events like "eatrocks" and "antlionstopfighting"

Main functions​

OnStart()​

  • Description: Initializes the behavior tree with a priority-based root node that sequences rock-eating (high-priority if recently attacked during a wall cooldown), standard combat, low-priority rock-eating, and a post-combat calm sequence. This function is automatically called when the brain is attached to an entity and starts running.
  • Parameters: None.
  • Returns: Nothing.

Events & listeners​

  • Listens to: None identified (the brain itself does not register listeners directly; it triggers events via inst:PushEvent).
  • Pushes:
    • "eatrocks" — when the antlion begins eating rocks to heal (high or low priority).
    • "antlionstopfighting" — to signal the end of the calm period and transition back to active combat behavior.
