Packet Commands

AzTick_

Bonsoir,

je cherche à faire un Packet pour executer des commande depuis un gui-client à la console du serveur mais je ne sais pas trop quoi mettre dans mon packet …

Qui aurait une classe ou un boût de code pour m’aider, où même une explication ?

Cordialement, AsKip_p

Salut,
Si tu n’as aucune donné à envoyer, tu peux laisser fromBytes et toBytes vide, tu as juste à faire l’action dans l’handler.

Bonsoir, c’est encore moi

J’ai créer mon packet, mais je bloque, je sais pas comment faire pour envoyer la commande à la console,
Qui pourrait m’aider et au passe si j’ai mal fais quelque chose me le dire ?

package fr.askip.testing.packets;

import cpw.mods.fml.common.network.simpleimpl.IMessage;
import cpw.mods.fml.common.network.simpleimpl.IMessageHandler;
import cpw.mods.fml.common.network.simpleimpl.MessageContext;
import io.netty.buffer.ByteBuf;

public class PacketCmdServer implements IMessage {

private Integer integer;

public PacketCmdServer(Integer i) {
this.integer = i;
}

@Override
public void fromBytes(ByteBuf buf) {
this.integer = Integer.valueOf(buf.readInt());
}

@Override
public void toBytes(ByteBuf buf) {
buf.writeInt(this.integer.intValue());
}

public static class Handler implements IMessageHandler <packetcmdserver, imessage="">{

@Override
public IMessage onMessage(PacketCmdServer message, MessageContext ctx) {
switch (message.integer.intValue()) {
case 0:
//envoyer la commande dans la console ICI
break;
}
return null;
}

}

}

Cordialement, AzTick</packetcmdserver,>

J’ai déplacé ton message dans l’autre discussion existante, ça ne sert à rien de créer deux discussions pour un même problème …

Il y a une fonction dans MinecraftServer pour exécuter une commande, par contre de tête je n’ai plus le nom.

Il me semble que je peut faire avec message context mais je n’ai plus la fonction en tête

Il te manque un constructeur sans argument dans la classe de ton paquet (obligatoire pour tous les paquets).
