J’avais pensais à çà aussi robin mais j’ai une erreur ….
public class Packetteleport implements IMessage { private static String text; public Packetteleport () { } public Packetteleport (String text) { this.text = text; } @Override public void fromBytes(ByteBuf buf) { text = ByteBufUtils.readUTF8String(buf); } @Override public void toBytes(ByteBuf buf) { ByteBufUtils.writeUTF8String(buf, text); } public static class Handler implements IMessageHandler <packetteleport ,="" imessage="">{ @Override public IMessage onMessage(Packetteleport message, MessageContext ctx) { switch(text) { case "gui1": System.out.println("Bonjour monsieur !"); player.setPositionAndUpdate(-22, 37, -694); break; case "gui2": System.out.println("Bonsoir monsieur !"); break; } return null; } } }
J’ai une erreur sur le player.setPositionAndUpdate(-22, 37, -694);</packetteleport>
Normal, il faut récupérer l’instance du joueur x)
Remplace player par ctx.getServerHandler().playerEntity
Oui je sais qu’il faut récupérer l’instance j’ai essayer plein de chose, mais je n’est rien trouvé de concluant mais tu viens de me sauver la vie .
Merci beaucoup
ROBIN IS GOD!!!
Salut je ne trouves pas comment faire des packets avec ma List <string>voila ma classe de packet:
public class PacketSpellsList implements IMessage { private static List <string>spellsList = new ArrayList<string>(); public PacketSpellsList() { } public PacketSpellsList(List <string>spellsList) { this.spellsList = spellsList; } @Override public void fromBytes(ByteBuf buf) { } @Override public void toBytes(ByteBuf buf) { } public static class Handler implements IMessageHandler <packetmana, imessage="">{ @Override public IMessage onMessage(PacketMana message, MessageContext ctx) { EntityPlayerMP player = ctx.getServerHandler().playerEntity; ExtendedEntityProps props = ExtendedEntityProps.get(player); props.spellsList = spellsList; return null; } } } ```</packetmana,></string></string></string></string>

En effet je l’ai expliqué dans le tutoriel vidéo.
toBytes :
Tu écrit la taille de la liste
Avec une boucle for tu initialise la liste.
fromBytes :
Tu lis la taille de la liste
Avec une boucle for de 0 au nombre lu juste avant, tu ajoute à la liste ce que tu lis.
J’ai fais ca:
package fr.sosoh.hogsmod.common.packet; import io.netty.buffer.ByteBuf; import java.util.ArrayList; import java.util.List; import net.minecraft.entity.player.EntityPlayerMP; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.nbt.NBTTagList; import cpw.mods.fml.common.network.ByteBufUtils; 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 fr.sosoh.hogsmod.common.entity.props.ExtendedEntityProps; public class PacketSpellsList implements IMessage { private static List <string>spellsList; public PacketSpellsList() { } public PacketSpellsList(List <string>spellsList) { this.spellsList = spellsList; } @Override public void fromBytes(ByteBuf buf) { for(int i = 0; i < spellsList.size(); i++) { String s = spellsList.get(i); if(s != null) { ByteBufUtils.writeUTF8String(buf, s); } } } @Override public void toBytes(ByteBuf buf) { for(int i = 0; i < spellsList.size(); i++) { this.spellsList.add(ByteBufUtils.readUTF8String(buf)); } } public static class Handler implements IMessageHandler <packetspellslist, imessage="">{ @Override public IMessage onMessage(PacketSpellsList message, MessageContext ctx) { EntityPlayerMP player = ctx.getServerHandler().playerEntity; ExtendedEntityProps props = ExtendedEntityProps.get(player); props.spellsList = spellsList; return null; } } }
et j’ai des erreurs dans mes logs:

Tu as inversé les fonctions toBytes et fromBytes : toBytes (doit être writeUTF8String), fromBytes (doit être readUTF8String)
Et même en inversant tu vas avoir un npe sur la lecture du paquet, car ta liste sera null. Il faut l’initialiser, après comme sa taille fera 0, ta boucle ne va pas fonctionner …
C’est pas pour rien que j’ai dit qu’il faut écrire et lire la taille de la liste.
J’ai pas compris ce que je dois faire 
@‘sosoh’:
J’ai pas compris ce que je dois faire
La fonction toBytes est l’écriture des tes variables sous formes de bytes :
1-écrire la taille de taille de ta liste (il est d’ailleurs plus préférable d’utiliser une array plutôt qu’une liste);
2-écrire tous les textes avec une boucle for.
La fonction fromBytes est la lecture de tes variables à partir de bytes:
1-lire la taille de ta liste;
2-Lire tous les String en fonction de la taille lue précédemment.
Qu’est-il advenu de AbstractMetroidPacket en 1.8 ?
Elle sert à quoi cette classe ?
Petit déterrage, mais je crois qu’on a le droit pour un tuto. Je ne suis pas là pour demander de l’aide mais pour proposer un example concret car au début (quand Blackout m’a référencé son tuto) je ne comprenais absolument rien. Donc mon example serait tout simplement faire exécuter une commande au serveur à partir du client (GUI).
Oui mais le but du tutoriel c’est d’utiliser les paquets, or ce que tu dis là c’est possible sans faire de paquets customs
Oui, mais c’est un example quand même de le faire avec un packet custom.
Oui mais inutile, or Robin a fait un tuto vidéo dans lequel tout est expliqué
Oui, mais ça concrétise quand même l’utilisation d’un packet. Ah oui, c’est pas faut pour la vidéo de robin.
Si je montre comment faire une commande avec des paquets certains vont le faire dans leur mod alors qu’il ne faut pas utiliser les paquets pour les commandes. Certes, ce serait une illustration, mais pas un exemple 
Je proposerais bien l’exemple d’un packet pour pouvoir utiliser une touche personnalisée parce que j’essaie de comprendre l’utilisation des packets, mais là je suis dans le potage complet.
Bon exemple comme le Keyboard est uniquement côté Client, nan? ^^’
