Multiplayer non-living entities do not appear

[matthewperiut]

I believe MobSpawnDataProvider works, but EntitySpawnDataProvider doesn't. Spawned entities that are using registerEntityHandlers instead of registerMobHandlers do not appear on server.

See matthewperiut/aether-fabric-b1.7.3#1 relevant code: com.matthewperiut.aether.entity.AetherEntities

    @EventListener
    public void registerEntityHandlers(EntityHandlerRegistryEvent event) {
        Registry.register(event.registry, MOD_ID.id("AetherLightning"), EntityAetherLightning::new);
        Registry.register(event.registry, MOD_ID.id("FlamingArrow"), EntityFlamingArrow::new);
        Registry.register(event.registry, MOD_ID.id("ZephyrSnowball"), EntityZephyrSnowball::new);
        Registry.register(event.registry, MOD_ID.id("PoisonNeedle"), EntityPoisonNeedle::new);
        Registry.register(event.registry, MOD_ID.id("PoisonDart"), EntityDartPoison::new);
        Registry.register(event.registry, MOD_ID.id("GoldenDart"), EntityDartGolden::new);
        Registry.register(event.registry, MOD_ID.id("EnchantedDart"), EntityDartEnchanted::new);
        Registry.register(event.registry, MOD_ID.id("CloudParachute"), EntityCloudParachute::new);
        Registry.register(event.registry, MOD_ID.id("FloatingBlock"), EntityFloatingBlock::new);
        Registry.register(event.registry, MOD_ID.id("FiroBall"), EntityFiroBall::new);
        Registry.register(event.registry, MOD_ID.id("LightningKnife"), EntityLightningKnife::new);
        Registry.register(event.registry, MOD_ID.id("NotchWave"), EntityNotchWave::new);
    }

Also seen in https://github.com/kozibrodka/BetterThanWolves where "Broad Head Arrow" does not work on multiplayer.

ALRIGHT I figured it out

1. implements EntitySpawnDataProvider

2. 
   public Identifier getHandlerIdentifier() {
       return MOD_ID.id("LightningKnife");
   }```

3. @HasTrackingParameters(trackingDistance = 50, sendVelocity = TriState.TRUE, updatePeriod = 1)

4. 
   public void registerEntityHandlers(EntityHandlerRegistryEvent event) {
       Registry.register(event.registry, MOD_ID.id("LightningKnife"), EntityAetherLightning::new);
       }

5. profit
