MovementStatesSystem

Package: com.hypixel.hytale.server.npc.systems

public class MovementStatesSystem extends SteppableTickingSystem

Updates NPC movement state flags based on the computed velocity. Runs after ComputeVelocitySystem. Delegates to Role.updateMovementState() which sets flags like walking, running, idle, etc. based on the velocity vector and the movement states component.

Entities with the role name "Empty_Role" are skipped. Exceptions during movement state updates are logged and do not crash the system.
