Slurperbrain

Based on game build 714014 | Last updated: 2026-02-27

Overview​

The SlurperBrain component implements AI behavior for the Slurper entity by constructing and running a behavior tree (BT). It inherits from the base Brain class and sets up a priority-based behavior tree during OnStart. The tree prioritizes panic responses (electric fence and general), followed by combat (ChaseAndAttack), and finally wandering back to a "home" location obtained via the KnownLocations component. This component is responsible solely for decision-making logic and does not manage entity state or rendering.

Usage example​

-- Add the component to an entity instance
inst:AddComponent("slurperbrain")

-- The brain is automatically initialized when the entity enters the world
-- via the SGworld stategraph or other triggers that invoke OnStart()

Dependencies & tags​

Components used: knownlocations (accessed via inst.components.knownlocations:GetLocation("home")).
Tags: None identified.

Properties​

No public properties are defined in the constructor. The class inherits from Brain, which manages internal behavior tree state (self.bt).

Main functions​

SlurperBrain:OnStart()​

  • Description: Initializes the behavior tree by constructing a priority node with ordered sub-tasks: PanicTrigger, ElectricFencePanicTrigger, ChaseAndAttack, and Wander. This function is called automatically when the entity's state graph enters the OnStart transition.
  • Parameters: None.
  • Returns: None.
  • Error states: None. Will fail if inst.components.knownlocations is missing, causing a runtime error when accessing GetLocation.

Events & listeners​

None. This component does not register or fire any events directly.
