Need help with PacketHandling for IExtendedEntityProperties[1.8]

ItsAMysteriousYT · August 12, 2015

Im trying to change some IEEP from a GuiScreen that pops up as soon as the player is spawned in the world. In that Gui, he has to set his name and gender and now i wanna aplly these variables to the EntityProperties. Im trying to do this with packethandling, but it won't work properly.

In the ActionPerformed method i make this:

@Override

public void actionPerformed(GuiButton b) {

if (b.id == 0) {

if (!(namefield.getText().equals("")) && !(surnamefield.getText().equals(""))&&this.genderGroup.getSelectedbutton()!=null) {

if (RLMPlayerProps.get(Minecraft.getMinecraft().thePlayer) != null) {

RealLifeMod.network.sendToServer(new SetPropertiesPackage(namefield.getText(), surnamefield.getText(), genderGroup.getSelectedbutton().getText()));

}

this.mc.displayGuiScreen(new GuiGamestart());

} else

ErrorMessage = "Please fill both fields!";

}

Here is my SetProperties Packet:

package itsamysterious.mods.reallifemod.core.packets;

import io.netty.buffer.ByteBuf;

import itsamysterious.mods.reallifemod.core.lifesystem.RLMPlayerProps;

import net.minecraftforge.fml.common.network.ByteBufUtils;

import net.minecraftforge.fml.common.network.simpleimpl.IMessage;

public class SetPropertiesPackage implements IMessage{

public String gender;

public String name;

public String surname;

protected SetPropertiesPackage(){

}

public SetPropertiesPackage(String name, String surname, String gender) {

this();

this.name = name;

this.surname = surname;

this.gender = gender;

}

@Override

public void fromBytes(ByteBuf buf) {

name = ByteBufUtils.readUTF8String(buf);

surname = ByteBufUtils.readUTF8String(buf);

gender = ByteBufUtils.readUTF8String(buf);

}

@Override

public void toBytes(ByteBuf buf) {

ByteBufUtils.writeUTF8String(buf, name);

ByteBufUtils.writeUTF8String(buf, surname);

ByteBufUtils.writeUTF8String(buf, gender);

}

And this is my PacketHandler:

package itsamysterious.mods.reallifemod.core.packets;

import itsamysterious.mods.reallifemod.core.lifesystem.RLMPlayerProps;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.util.IThreadListener;

import net.minecraft.world.World;

import net.minecraft.world.WorldServer;

import net.minecraftforge.fml.common.network.simpleimpl.IMessageHandler;

import net.minecraftforge.fml.common.network.simpleimpl.MessageContext;

public class PacketHandler implements IMessageHandler<SetPropertiesPackage, SetPropertiesPackage>{

public PacketHandler() {

super();

}

@Override

public SetPropertiesPackage onMessage(final SetPropertiesPackage message, MessageContext ctx) {

final EntityPlayer player = ctx.getServerHandler().playerEntity;

IThreadListener mainThread = (WorldServer) ctx.getServerHandler().playerEntity.worldObj; // or Minecraft.getMinecraft() on the client

mainThread.addScheduledTask(

new Runnable() {

@Override

public void run() {

RLMPlayerProps.get(player).name=message.name;

RLMPlayerProps.get(player).surname=message.surname;

RLMPlayerProps.get(player).gender=message.gender;

}

});

return null;

}

Did you register the packet?

Have you put a print statement on the receiving side to see if it arrives and what it says for the variables when it does?

ItsAMysteriousYT · August 12, 2015

Yes, i registered the packet and no i haven't got a println, buzt ingame i show the name on a second gui. And that sais null, null

delpi · August 12, 2015

Put a print statement in the packet handler and see what it says there.

Right after 'public void run() {'

Also what you just said made me think of something. You are sending your information to the server to update extended properties for the player. Then you are looking in your GUI and seeing it is null, null. Where are you sending the updated extended properties from the server back to the client?

Ernio · August 12, 2015

1. You don't need to call this() in constructor (unless it does domething, which it doesn't).

2. Same goes for super() - empty constructors don't need it ;_;

3. Hint: Don't access same data multiple times - get RLMPlayerProps ONCE, then use instance.

4. Finally after simple fixes:

but it won't work properly.

What exacly? What can be wrong:

When sending packet: you are passing null/empty strings. (most likely)

When receiving packet: your #get is not working correctly.

5. Tip: Make server close player's start-game gui, only after name/surname are correct. (packet might not arrive or data might be "bad").

Okay wait, i think i ned a closer explanation for how i need to use those packets. Why send them to server and then to client? Why i cant do sendToAll,cuz that does not work too.

ItsAMysteriousYT · August 12, 2015

Most likely issue: your no-argument constructor is protected so FML cannot access it.

oh lol

ItsAMysteriousYT · August 12, 2015

Okay i made the constructor public and also added a print statement. Nothing chaned. Once i closed the gui, minecraft freezes and the error is shown. Also name+Surname still is null,null.

This is the error i get:
