Minecraft gives error when using custom packets

[FoxWare]

Hi, I maked a custom packet to with the scope to use Minecraft.partciles.emitParticlesAtEntity(), but minecraft give me an error:
 

Internal Exception: io.netty.handler.codec.EncoderException: java.lang.RuntimeException: ConnectionProtocol unknown: me.foxware.potions.network.packets.SEmitParticlesPacket@389b00f

Here the packet code:

public class SEmitParticlesPacket implements IPacket<IClientPlayNetHandler> {
	private Minecraft client = Minecraft.getInstance();
	
	private int entityID;
	private IParticleData particle;
	private int lifeTime;
	
	public <T extends IParticleData> SEmitParticlesPacket(Entity entityIn, T particleIn, int lifeTimeIn) {
		this.entityID = entityIn.getEntityId();
		this.particle = particleIn;
		this.lifeTime = lifeTimeIn;
	}
	
	@Override
	public void readPacketData(PacketBuffer bufIn) throws IOException {
		ParticleType<?> particleType = Registry.PARTICLE_TYPE.getByValue(bufIn.readInt());
		if(particleType == null) {
			particleType = ParticleTypes.BARRIER;
		}
		
		this.entityID = bufIn.readInt();
		this.lifeTime = bufIn.readInt();
		this.particle = readParticle(bufIn, particleType);
	}

	@Override
	public void writePacketData(PacketBuffer bufIn) throws IOException {
		bufIn.writeInt(Registry.PARTICLE_TYPE.getId(this.particle.getType()));
		bufIn.writeInt(this.entityID);
		bufIn.writeInt(this.lifeTime);
		
		this.particle.write(bufIn);
	}
	private <T extends IParticleData> T readParticle(PacketBuffer bufIn, ParticleType<T> particleType) {
		return particleType.getDeserializer().read(particleType, bufIn);
	}
	
	public int getEntityID() {
		return this.entityID;
	}
	public IParticleData getParticle() {
		return this.particle;
	}
	public int getLifeTime() {
		return this.lifeTime;
	}
	
	@Override
	public void processPacket(IClientPlayNetHandler handlerIn) {
		this.client.particles.emitParticleAtEntity(this.client.world.getEntityByID(getEntityID()), getParticle(), getLifeTime());
	}
}

Here where is used:
 

@SubscribeEvent
public static void onEntityDeath(LivingDeathEvent eventIn) throws InterruptedException {
	LivingEntity entity = eventIn.getEntityLiving();
	if(entity.getActivePotionEffect(ModEffects.IMMORTALITY.get()) != null) {
		entity.setHealth(entity.getMaxHealth() * 25 / 100);
		entity.removePotionEffect(ModEffects.IMMORTALITY.get());
		
		entity.world.playSound(null, entity.getPosX(), entity.getPosY(), entity.getPosZ(), SoundEvents.ITEM_TOTEM_USE, entity.getSoundCategory(), 1.0F, 1.0F);
		for(PlayerEntity p : entity.world.getPlayers()) {
			((ServerPlayerEntity) p).connection.sendPacket(new SEmitParticlesPacket(entity, ParticleTypes.TOTEM_OF_UNDYING, 30));
		}
		
		eventIn.setCanceled(true);
	}
}

Thanks for everyone helps me!

Use Forge's network system.

Ok, i do something but are some issues...

Here Packet class:

public class EmitParticlesPacket {
	private int entityID;
	private IParticleData particle;
	private int lifeTime;
	
	public <T extends IParticleData> EmitParticlesPacket(Entity entityIn, T particleIn, int lifeTimeIn) {
		this.entityID = entityIn.getEntityId();
		this.particle = particleIn;
		this.lifeTime = lifeTimeIn;
	}
	
	public EmitParticlesPacket(PacketBuffer bufIn) throws IOException {
		ParticleType<?> particleType = Registry.PARTICLE_TYPE.getByValue(bufIn.readInt());
		if(particleType == null) {
			particleType = ParticleTypes.BARRIER;
		}
		
		this.entityID = bufIn.readInt();
		this.lifeTime = bufIn.readInt();
		this.particle = readParticle(bufIn, particleType);
	}

	public void encoder(EmitParticlesPacket msg, PacketBuffer bufIn) throws IOException {
		bufIn.writeInt(Registry.PARTICLE_TYPE.getId(this.particle.getType()));
		bufIn.writeInt(this.entityID);
		bufIn.writeInt(this.lifeTime);
		
		this.particle.write(bufIn);
	}
	
	private <T extends IParticleData> T readParticle(PacketBuffer bufIn, ParticleType<T> particleType) {
		return particleType.getDeserializer().read(particleType, bufIn);
	}
	
	public int getEntityID() {
		return this.entityID;
	}
	public IParticleData getParticle() {
		return this.particle;
	}
	public int getLifeTime() {
		return this.lifeTime;
	}
	
	public static void handle(EmitParticlesPacket msg, Supplier<NetworkEvent.Context> ctx) {
		ctx.get().enqueueWork(() -> {
			if(ctx.get().getDirection().getReceptionSide().equals(LogicalSide.CLIENT)) {
				Minecraft client = Minecraft.getInstance();
				client.particles.emitParticleAtEntity(client.world.getEntityByID(msg.getEntityID()), msg.getParticle(), msg.getLifeTime());
			}
		});
		ctx.get().setPacketHandled(true);
	}
}

 

Here the PacketHandler... here eclipse gives some errors at ISTANCE.registerMessage():
2 arg: The type EmitParticlesPacket does not define encoder(MSG, PacketBuffer) that is applicable here
3 arg: The constructed object of type EmitParticlesPacket is incompatible with the descriptor's return type: MSG
4 arg: The type EmitParticlesPacket does not define handle(MSG, Supplier<NetworkEvent.Context>) that is applicable here
Here the class of Packet Handler:

public class ModPacketHandler {
	private static final String PROTOCOL_VER = "1";
	public static final SimpleChannel INSTANCE = NetworkRegistry.newSimpleChannel(
		new ResourceLocation(FurtherPotionsMain.MODID, "main"),
		() -> PROTOCOL_VER,
		PROTOCOL_VER::equals,
		PROTOCOL_VER::equals
	);
	
	public static void register() {
		int ID = 0;
		INSTANCE.registerMessage(ID++, EmitParticlesPacket.class, EmitParticlesPacket::encoder, EmitParticlesPacket::new, EmitParticlesPacket::handle);
	}
}

Learn a bit more about Functional Interfaces. The function is non-static, so why do you need to pass in an instance you already have?

The decoder requires a return value, something you are not providing.

Look at the parameter needed to supply the method.
