SpawnEffect

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

public interface SpawnEffect

Contract for spawning particle effects when an NPC appears in the world. Implementers provide a particle system ID, an offset from the NPC’s position, and a view distance for player visibility. The default spawnEffect method rotates the offset by the entity’s yaw, collects nearby players within the view distance using a spatial query, and dispatches the particle effect.

Abstract Methods

Return Type	Signature
String	getSpawnParticles()
Vector3d	getSpawnParticleOffset()
double	getSpawnViewDistance()

Default Methods

Modifier	Return Type	Signature
default	void	spawnEffect(@Nonnull Vector3d position, @Nonnull Vector3f rotation, @Nonnull ComponentAccessor<EntityStore> componentAccessor)

The default implementation: returns early if getSpawnParticles() is null or empty. Otherwise, applies the yaw rotation from rotation to the particle offset, adds the entity position, queries the player spatial resource for nearby players, and calls ParticleUtil.spawnParticleEffect.
