Carnivalgame Herding Chick Brain

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

Overview​

CarnivalGame_Herding_ChickBrain defines the behavior tree for a chick entity participating in the herding minigame. It orchestrates three core behaviors using a priority node:

  1. Running away from entities with tags "minigame_participator" or "minigame_spectator" (e.g., other players or chicks).
  2. Avoiding the herding station region ("carnivalgame_herding_station" tag).
  3. Wandering within a maximum radius of its home location.

The AI only activates when the entity has a locomotor component, and uses knownlocations to retrieve the "home" position for movement.

Usage example​

local inst = CreateEntity()
inst:AddTag("carnivalgame_herding_chick")
inst:AddComponent("knownlocations")
inst:AddComponent("locomotor")
inst:AddComponent("behaviour")
inst:AddComponent("companion")
inst:AddBrain("carnivalgame_herding_chick_brain")

Dependencies & tags​

Components used:

  • locomotor (required for activation)
  • knownlocations (to fetch "home" location)

Tags:

  • Adds "minigame_participator" or "minigame_spectator" dynamically (via RunAway behavior)
  • Checks for "carnivalgame_herding_station" tag to avoid station areas

Properties​

No public properties.

Main functions​

OnStart()​

  • Description: Initializes the behavior tree with a priority-ordered node hierarchy: runaway (from players/spectators), runaway (from home station), then wandering. Only runs while the locomotor component exists.
  • Parameters: None.
  • Returns: Nothing.
  • Error states: Behavior tree (self.bt) is only constructed if self.inst.components.locomotor is non-nil at activation time.

Events & listeners​
