Ok, this may potentially be the most nooby question you will ever see, and it might make you want to shoot yourself. Please dont. So, I want to give the player an item when I click a button, but this isn't working

 

Button:

public void actionPerformed(GuiButton guibutton){
	if(guibutton.id == 24){
		// Sending packet to server
		IMessage msg = new SimplePacket.SimpleMessage(500, true);
		PacketHandler.net.sendToServer(msg);

	}
}

 

PacketHandler:

package com.bugzoo.FinancialMod;

import cpw.mods.fml.common.network.NetworkRegistry;
import cpw.mods.fml.common.network.simpleimpl.SimpleNetworkWrapper;
import cpw.mods.fml.relauncher.Side;

public class PacketHandler
{
public static SimpleNetworkWrapper net;
public static void initPackets()
{
net = NetworkRegistry.INSTANCE.newSimpleChannel("YourModId".toUpperCase());
registerMessage(SimplePacket.class, SimplePacket.SimpleMessage.class);
}
private static int nextPacketId = 0;
private static void registerMessage(Class packet, Class message)
{
	net.registerMessage(packet, message, nextPacketId, Side.CLIENT);
	net.registerMessage(packet, message, nextPacketId, Side.SERVER);
	nextPacketId++;
}
}

 

SimplePacket:

package com.bugzoo.FinancialMod;

import io.netty.buffer.ByteBuf;
import net.minecraft.client.Minecraft;
import net.minecraft.item.ItemStack;

import com.bugzoo.FinancialMod.SimplePacket.SimpleMessage;

import cpw.mods.fml.common.network.simpleimpl.IMessage;
import cpw.mods.fml.common.network.simpleimpl.IMessageHandler;
import cpw.mods.fml.common.network.simpleimpl.MessageContext;

public class SimplePacket implements IMessageHandler<SimpleMessage, IMessage>
{

Minecraft mc;
@Override
public IMessage onMessage(SimpleMessage message, MessageContext ctx)
{
// just to make sure that the side is correct
if (ctx.side.isClient())
{
mc.thePlayer.inventory.addItemStackToInventory(new ItemStack(FinancialMod.Wallet));
int integer = message.simpleInt;
boolean bool = message.simpleBool;
}
return message;
}
public static class SimpleMessage implements IMessage
{
	private int simpleInt;
	private boolean simpleBool;
		// this constructor is required otherwise you'll get errors (used somewhere in fml through reflection)
	public SimpleMessage() {}
	public SimpleMessage(int simpleInt, boolean simpleBool)
	{
		this.simpleInt = simpleInt;
		this.simpleBool = simpleBool;
	}
	@Override
	public void fromBytes(ByteBuf buf)
	{
		// the order is important
		this.simpleInt = buf.readInt();
		this.simpleBool = buf.readBoolean();
	}
	@Override
		public void toBytes(ByteBuf buf)
	{
		buf.writeInt(simpleInt);
		buf.writeBoolean(simpleBool);
}
}
}

a) Why do you register your packet for being sent both ways? It should only go client -> server.

b) Why do you send and integer and a boolean when you never use them?

c) You need to use the serverside player when receiving the packet, you get it from the MessageContext.

d) Your packet has the potential of allowing players to infinitely create your Item over and over again. The server needs to check if it is ok for the client to send that packet, otherwise hacked clients could exploit it.

 

How do I get it from the MessageContext?

  • Author

MessageContext#getServerHandler().playerEntity

 

Ok, so now when I press it, it says "a fatal error has occured, this connection is terminated"

Post the full log.

Don't return the message in onMessage! What you return there is send as a response to whoever sent the incoming packet. Normally you want to return null there. And again: Do not register your packets for both sides! (If you had fixed that the error would be different).

 

Where am I registering it on both sides?

  • Author

registerMessage

in your PacketHandler class.

 

I fixed that, now nothing is happening at all when I press the button

  • Author

Show your updated PacketHandler class and the Message & MessageHandler.

 

PacketHandler:

package com.bugzoo.FinancialMod;

import cpw.mods.fml.common.network.NetworkRegistry;
import cpw.mods.fml.common.network.simpleimpl.SimpleNetworkWrapper;
import cpw.mods.fml.relauncher.Side;

public class PacketHandler
{
public static SimpleNetworkWrapper net;
public static void initPackets()
{
net = NetworkRegistry.INSTANCE.newSimpleChannel("YourModId".toUpperCase());
registerMessage(SimplePacket.class, SimplePacket.SimpleMessage.class);
}
private static int nextPacketId = 0;
private static void registerMessage(Class packet, Class message)
{
	net.registerMessage(packet, message, nextPacketId, Side.CLIENT);
	nextPacketId++;
}
}

 

SimpleMessage:

package com.bugzoo.FinancialMod;

import io.netty.buffer.ByteBuf;
import net.minecraft.client.Minecraft;
import net.minecraft.item.ItemStack;

import com.bugzoo.FinancialMod.SimplePacket.SimpleMessage;

import cpw.mods.fml.common.network.simpleimpl.IMessage;
import cpw.mods.fml.common.network.simpleimpl.IMessageHandler;
import cpw.mods.fml.common.network.simpleimpl.MessageContext;

public class SimplePacket implements IMessageHandler<SimpleMessage, IMessage>
{

Minecraft mc;
@Override
public IMessage onMessage(SimpleMessage message, MessageContext ctx)
{
// just to make sure that the side is correct
if (ctx.side.isClient())
{
	ctx.getServerHandler().playerEntity.inventory.addItemStackToInventory(new ItemStack(FinancialMod.Wallet));
}
return null;
}
public static class SimpleMessage implements IMessage
{
	private int simpleInt;
	private boolean simpleBool;
		// this constructor is required otherwise you'll get errors (used somewhere in fml through reflection)
	public SimpleMessage() {}
	public SimpleMessage(int simpleInt, boolean simpleBool)
	{
		this.simpleInt = simpleInt;
		this.simpleBool = simpleBool;
	}
	@Override
	public void fromBytes(ByteBuf buf)
	{
		// the order is important
		this.simpleInt = buf.readInt();
		this.simpleBool = buf.readBoolean();
	}
	@Override
		public void toBytes(ByteBuf buf)
	{
		buf.writeInt(simpleInt);
		buf.writeBoolean(simpleBool);
}
}
}

 

Button:

public void actionPerformed(GuiButton guibutton){
	if(guibutton.id == 24){
		// Sending packet to server
		IMessage msg = new SimplePacket.SimpleMessage(500, true);
		PacketHandler.net.sendToServer(msg);
	}
}

a) Now you register your packet to be received on the Client, but you sent it to the server.

b) In your MessageHandler you check for client side, but your packet is only ever received on the server.

c) You are still sending unused data in your packet.

 

How do I send it to the client? I've tried this code, but the player variable doesn't exist

public void actionPerformed(GuiButton guibutton){
	if(guibutton.id == 24){
		// Sending packet to client
		if (player instanceof EntityPlayerMP)
		{
		IMessage msg = new SimplePacket.SimpleMessage(800, false);
		PacketHandler.net.sendTo(msg, (EntityPlayerMP)player);
		}
	}
}

You should send it to the server! You need to register it as being received on the server, too.

 

You said about sending unused data, where am I doing that?

  • Author

It doesn't matter. Static inner classes behave just like a normal class.

 

Ok, Now

 

I stopped sending unused data

I'm now sending to the server

Now checks for server and recieves on server

 

But still, nothing happens when I click the button
