No packet on the multiplayer ?

[godbaba]

When I send a packet to the server If I am in the client it does work but in the multiplayer it doesnt work...

 

I send my packet :

                    EntityClientPlayerMP pl = (EntityClientPlayerMP) player;       
                    pl.sendQueue.addToSendQueue(stream.makePacket("netherfors"));

 

And my server packet handler :

 

package netherfors;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.network.INetworkManager;
import net.minecraft.network.packet.Packet250CustomPayload;
import netherfors.misc.PacketReadStream;
import cpw.mods.fml.common.network.IPacketHandler;
import cpw.mods.fml.common.network.Player;

public class ServerModPacketHandler implements IPacketHandler {

@Override
public void onPacketData(INetworkManager manager,
		Packet250CustomPayload packet, Player player) {

	EntityPlayer p = (EntityPlayer) player;

	if(packet.channel.equals("netherfors")){
		PacketReadStream data = new PacketReadStream(packet);
		if(data.readInt() == 1001){
			p.addChatMessage("Done!");
		}

		if(data.readInt() == 2002){
			System.out.println("2002");
			destroyPhoxNote(p);
		}	
	}
}

public void destroyPhoxNote(EntityPlayer player){
	player.closeScreen();
	player.inventory.decrStackSize(player.inventory.currentItem, 1);
	player.addChatMessage("You have successfully learned what this Phox Note teaches!");
}

}

 

Can anyone help with this ?

how do you register your packet handler ?

[godbaba]

I can get the packet in single player so yes!

 

	IPacketHandler packetServer = new ServerModPacketHandler();
	IPacketHandler packetClient = new ClientModPacketHandler();
	NetworkRegistry.instance().registerChannel(packetServer, "netherfors", Side.SERVER);
	NetworkRegistry.instance().registerChannel(packetClient, "netherfors", Side.CLIENT);

	IPacketHandler packetServer = new ServerModPacketHandler();
	IPacketHandler packetClient = new ClientModPacketHandler();
	NetworkRegistry.instance().registerChannel(packetServer, "netherfors", Side.SERVER);
	NetworkRegistry.instance().registerChannel(packetClient, "netherfors", Side.CLIENT);

 

and what method this is in?

[godbaba]

I am still in 1.5.2 and thats in the :

 

@Init
public void init(FMLInitializationEvent event){}

 

[hydroflame]

can you try println inside your server packet hanlder constructor to see if it actually goes through and another println at the begining of the onPacketData method ? (before any if ) and see it this one comes up

[godbaba]

I added this code to the handler :

 

	System.out.println("PACKET ARRIVED!");
	System.out.println(packet.channel);
	System.out.println(data.readInt());

 

And channel is ok , packet is arriving , integer is running but the if statement its not working it looks like ... :?

[godbaba]

And I just realised that I am getting this exception when I try to data.readInt()

And this is how I handle my packets

ok well how are you sending and making this packet, if it fails it means you did not send the right thing

 

edit: btw im the author of that tutorial and those class

It is quite interesting I solved problem but it is weird...

 

if(data.readInt() == 2002)

 

is not working...

 

int id = data.readInt();
if(id ==2002)

 

is working...

 

Weird but it is working

[GotoLink]

That is because you can only read once the data at a given place in the packet.

Ohhh Thanks for the explanation
