FeatureEvaluatorHelper

Package: com.hypixel.hytale.server.npc.asset.builder

public class FeatureEvaluatorHelper

Manages feature provider evaluation for builders. Tracks a list of provider evaluators, supports locking (making the list immutable), and validates that referenced features are provided and component requirements are met. Used to ensure that actions and motions in the NPC behavior tree have access to the target types they need (Player, NPC, Position, etc.).
