SteeringSystem

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

public class SteeringSystem extends SteppableTickingSystem

Applies the computed steering vectors (body and head) to the NPC’s active motion controller. Runs after AvoidanceSystem and after KnockbackSystems.ApplyKnockback, and before TransformSystems.EntityTrackerUpdate.

Constructor

public SteeringSystem(@Nonnull ComponentType<EntityStore, NPCEntity> npcEntityComponent)

Query

Matches entities with NPCEntity and TransformComponent.

Tick Logic

@Override
public void steppedTick(
    float dt,
    int index,
    @Nonnull ArchetypeChunk<EntityStore> archetypeChunk,
    @Nonnull Store<EntityStore> store,
    @Nonnull CommandBuffer<EntityStore> commandBuffer
)

Delegates to role.getActiveMotionController().steer(ref, role, bodySteering, headSteering, dt, commandBuffer).

When debug motion steering is enabled, logs detailed velocity and heading information. On IllegalStateException or IllegalArgumentException, removes the entity.

Parallelism

Returns false — this system does not run in parallel.
