Fruitdragonbrain

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

Overview​

FruitDragonBrain defines the behavior tree for the Fruit Dragon boss entity. It orchestrates core AI behaviors including chasing and attacking targets, fleeing when the "LostChallenge" timer is active, homing in on its tracked home entity, and wandering when the home is stationary or no home exists. It relies heavily on the entitytracker component to locate the home entity and uses logic to adjust movement and facing behavior based on whether the home is mobile (e.g., carried by a player). This brain is typically attached to a boss prefab to enable dynamic, context-sensitive responses to gameplay events.

Usage example​

local inst = CreateEntity()
inst:AddComponent("entitytracker")
inst:AddComponent("locomotor")
inst:AddComponent("timer")
inst:AddBrain("fruitdragonbrain")

Dependencies & tags​

Components used: entitytracker, locomotor, timer, inventoryitem (via GetGrandOwner on the home entity) Tags: None identified.

Main functions​

OnStart()​

  • Description: Initializes and assigns the behavior tree (self.bt) for the Fruit Dragon. The tree begins with high-priority panic and combat nodes, followed by home-following and home-based wandering logic, and finally falls back to generic wandering.
  • Parameters: None.
  • Returns: Nothing.

Events & listeners​

  • Listens to: None explicitly registered in this file; event-driven state changes (e.g., panicing timer) are evaluated via inline function nodes within the behavior tree (e.g., WhileNode).
  • Pushes: None explicitly in this file.
