Hello guys!

 

I tried to test my mod in an LAN world and started Minecraft two times, then I tried to create a lan world on one instance and connect from the other one.

I can join the world, but then the connecting client immediately crashes. The hosting client shows in the chat that I joined the game and left immediately. The crash is caused by a packed which is sent to my mod's channel but wasn't registered with it. I'm using a PacketHandler based on a SimpleNetworkWrapper. I'll attach the code I'm using.

 

This is the error I get:

Obviously, my channel receives a packet with the discriminator -97 which was never used by me, thus it's not listed in the discriminator list.

This error only happens when I try to connect to a LAN world, it is not caused when I connect to a server.

 

I hope anyone has an Idea how I can fix this issue or why it's caused.

1. Need more code (packet example, registration of packets, idk, events maybe, login etc.)

My 1st though was bad int->byte casting, but you say it works for server, so nope.

 

2. My humble criticism:

 

 

56542127.jpg

 

There is so much useless, overcomplicated stuff here. You are making it look worse and be slower without any gain in return.

 

Stuff like:

@Override
public void fromBytes(ByteBuf buf) {
	this.decodeFrom(buf);
}

@Override
public void toBytes(ByteBuf buf) {
	this.encodeInto(buf);
}

Cmon!

Why?

byte IDb = (byte) ID;
ID = IDb;

Those annotations and reflection - damn.

Or, idk - the fact that you are having this:

BasePacket implements IMessage, IMessageHandler<BasePacket, BasePacket>

I wouldn't be surprised if the error was from your design - you should NOT have Message and Handles in one class.

 

 

 

Ofc. that is a humble opinion, so don't mind me. :D Trying to find something that might help, but for now, feed us with more code, error might somwehere else.

1.7.10 is no longer supported by forge, you are on your own.

OK, so here you are:

 

Handler initialization: (Init)

Magicum.packetHandler = new PacketHandler(Magicum.MODID);

 

Packet registration: (After initialization)

 

Magicum.packetHandler.registerPacket(0, PacketUpdateRequest.class);
Magicum.packetHandler.registerPacket(1, PacketPlayerMana.class);
Magicum.packetHandler.registerPacket(2, PacketPlayerMagicum.class);
Magicum.packetHandler.registerPacket(3, PacketElementaryExtractor.class);
Magicum.packetHandler.registerPacket(4, PacketPlayerElements.class);
Magicum.packetHandler.registerPacket(5, PacketPlayerChargeTime.class);
Magicum.packetHandler.registerPacket(6, PacketPlayerElementCooldown.class);
Magicum.packetHandler.registerPacket(7, PacketPlayerCastMagic.class);
Magicum.packetHandler.registerPacket(8, PacketPlayerMagicData.class);
Magicum.packetHandler.registerPacket(9, PacketPlayerVelocity.class);

 

 

Packet Example: (PacketUpdateRequest)

 

package com.bedrockminer.magicum.common.network.packets;

import io.netty.buffer.ByteBuf;
import minersbasic.api.network.BasePacket;
import minersbasic.api.network.PacketHandler.ToServer;
import net.minecraft.entity.player.EntityPlayer;

import com.bedrockminer.magicum.common.entitydata.PlayerData;

@ToServer
public class PacketUpdateRequest extends BasePacket {

@Override
public void encodeInto(ByteBuf buffer) {
}

@Override
public void decodeFrom(ByteBuf buffer) {
}

@Override
public BasePacket handleClientSide(EntityPlayer player) {
	return null;
}

@Override
public BasePacket handleServerSide(EntityPlayer player) {
	PlayerData.get(player).syncAll();
	return null;
}

}

 

 

Packet Example: (PacketPlayerMana)

 

package com.bedrockminer.magicum.common.network.packets;

import io.netty.buffer.ByteBuf;
import minersbasic.api.network.BasePacket;
import minersbasic.api.network.PacketHandler.ToClient;
import net.minecraft.entity.player.EntityPlayer;

import com.bedrockminer.magicum.common.entitydata.PlayerData;

@ToClient
public class PacketPlayerMana extends BasePacket {

private int mana;

public PacketPlayerMana() {
}

public PacketPlayerMana(int mana) {
	this.mana = mana;
}

@Override
public void encodeInto(ByteBuf buffer) {
	buffer.writeInt(this.mana);
}

@Override
public void decodeFrom(ByteBuf buffer) {
	this.mana = buffer.readInt();
}

@Override
public BasePacket handleClientSide(EntityPlayer player) {
	PlayerData.get(player).setMana(this.mana);
	return null;
}

@Override
public BasePacket handleServerSide(EntityPlayer player) {
	return null;
}

}

 

 

Login information:

The client hosting the LAN world is a "cracked" account which is not logged in to Minecraft. The client trying to connect is my own minecraft account. This has worked previously.

 

I have no events triggered on receiving packets.

I have two events triggered when connecting to a server:

 

@SubscribeEvent(priority = EventPriority.NORMAL)
public void onEntityConstruction(EntityConstructing e) {
	// Registering ExtendedEntityProperties
	if (e.entity instanceof EntityPlayer) {
		PlayerData.register((EntityPlayer) e.entity);
	}
}

@SubscribeEvent(priority = EventPriority.NORMAL)
public void onEntityJoinWorld(EntityJoinWorldEvent e) {
	// Synchronizes Entity Properties
	if (e.entity instanceof EntityPlayer) {
		PlayerData.get((EntityPlayer) e.entity).requestSyncAll();
	}
}

 

the requestSyncAll method sends a RequestUpdatePacket to the server if it is called on client side. The answer to the request is a series of sync packets. (Like the mana packet)

PlayerData is an implementation of IExtendedEntityProperties.

 

Note:

I created this ToServer/ToClient stuff to prevent packets to be sent to the wrong side accidentially. If you have a send call for a packet which does nothing on that side you send it to, but you think it does, it's more convenient to get an error than to search for an empty method. (My opinion, you may do it differently)

Sorry, but I have literally no idea what's up with this "-97".

 

As to whole system, you are doing a lot of stuff bad and oldschool (outdated).

The design itself if so far from common ones that it is almost a blind search, but 1st things 1st:

 

1. You made hella lot wrapping around your packets, yet you didn't do simplest thing:

You can hold:

private byte nextPacketId;

In your PacketHandler class and in registerMessage do this.nextPacketId++;

Make internals be internal.

 

-------------------------------------------

 

2. I alredy mentioned that Message and Handler should be separated into 2 classes or class + nested handler.

Why? Because directly from doing stuff like you just did you will get errors that are IMPOSSIBLE to track without previous knowledge.

Lets take this example:

public class Test implements IMessage, IMessageHandler<Test, IMessage>
{
public Test() {System.out.println("CONS: " + this);}

@Override
public IMessage onMessage(Test message, MessageContext ctx)
{
	System.out.println("THIS: " + this);
	System.out.println("MSG: " + message);
	return null;
}

@Override
public void fromBytes(ByteBuf buf)
{System.out.println("READ: " + this);}

@Override
public void toBytes(ByteBuf buf)
{System.out.println("SEND: " + this);}
}

And register it as something like this:

registerMessage(Test.class, Test.class, Side.CLIENT) // packet, handler, side

We will be sending packet from server.

 

This is the output:

[server thread/INFO] [.network.Test:<init>:13]: CONS: .network.Test@197fd644
[server thread/INFO] [.network.Test:toBytes:29]: SEND: .network.Test@197fd644
[Netty Local Client IO #0/INFO] [.network.Test:<init>:13]: CONS: .network.Test@6dca2193
[Netty Local Client IO #0/INFO] [.network.Test:fromBytes:25]: READ: .network.Test@6dca2193
[Netty Local Client IO #0/INFO] [.network.Test:onMessage:18]: THIS: .network.Test@4546c234
[Netty Local Client IO #0/INFO] [.network.Test:onMessage:19]: MSG:.network.Test@6dca2193

BOOOOOOOM

 

If you look closely - your data received is TOTALLY false (null?). So yeah... Drop your design, bro.

 

Edit (if you don't see it):

* "THIS: .network.Test@4546c234" is a handler that receives message, but handler != packetReceived so you cannot use this.field directly inside it, as you are doing in your handlers.

Ah, missed that one "message.handle..."

Anway, here comes 3rd thing!!!

Notice (in point 2) thread prints - yeah, you should NEVER have Netty thread doing stuff for Minecraft, NEVER EVER.

 

I strongly suggest rewriting your system, good one (but can be better):

I am wondering how the hell it works for you without losing packets over thread-unsafety and all that stuff you are doing (Disclaimer: Maybe I missed something).

1.7.10 is no longer supported by forge, you are on your own.
