Crash Entity Extended Properties

Sacrée brigitte

Salut tout le monde
J'ai crée un player extended entity props mais au moment de get un byte depuis un block via un system.out.println, mon jeu crash :
voici le crash report

Merci d'avance

Quel est la classe de ton paquet que tu envois ?

Je me trompe peut être mais je pense qu'il y a une erreur ici :


PacketKitSecours packetkitsecours = new PacketKitSecours(this.kitSecoursNumber);
ZombarCraftMod.network.sendToServer(packetkitsecours);

if (!player.worldObj.isRemote)
{
EntityPlayerMP player1 = (EntityPlayerMP) player;
ZombarCraftMod.network.sendTo(packetkitsecours, player1);
}

Tu envois le paquet au serveur à chaque fois, donc si tu lances ton mod côté serveur, il va s'envoyer un paquet à lui-même.

Sacrée brigitte

Voici la class du packet


package mrplaigon.zombarcraftserver.zombarcraftmod.common.packet;

import io.netty.buffer.ByteBuf;
import mrplaigon.zombarcraftserver.zombarcraftmod.common.extendedentityproperties.ExtendedEntityPropertiesPlayer;
import net.minecraft.entity.player.EntityPlayerMP;
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 PacketKitSecours implements IMessage
{

private static byte kitSecoursNumber;

public PacketKitSecours()
{

}

public PacketKitSecours(byte kitSecoursNumber)
{
this.kitSecoursNumber = kitSecoursNumber;
}

@Override
public void fromBytes(ByteBuf buf) 
{
buf.writeByte(kitSecoursNumber);
}

@Override
public void toBytes(ByteBuf buf) 
{
this.kitSecoursNumber = buf.readByte();
}
public static class Handler implements IMessageHandler <packetkitsecours, imessage="">{

@Override
public IMessage onMessage(PacketKitSecours message, MessageContext ctx) 
{
EntityPlayerMP player = ctx.getServerHandler().playerEntity;
ExtendedEntityPropertiesPlayer props = ExtendedEntityPropertiesPlayer.get(player);
props.kitSecoursNumber = kitSecoursNumber;
return null;
}

}
}

Et pour ce que tu m'as proposé, quel code aurais-tu mis à la place ? Car pour l'instant je ne lançais mon mod qu'en solo pas en serveur.
Mon packet est bien déclaré dans ma main class il a pour SIDE server, et un bon discriminator, et pour ceux qui penserait que cela viendrait du SIDE j'ai mis client pour voir toujours pareil.</packetkitsecours,>

fromBytes = depuis le bytes -> read
toBytes = vers les bytes -> write

Tu as inversé les deux.

Ok merci tout marche
