Résolu Envoi de packets en 1.12.2
-
Bonjour,
je suis actuellement sur un mod en 1.12.2 pour un serveur et je cherche comment utiliser un SimpleNetworkWrapper pour envoyer des packets.
Je pense qu’il y a une histoire de proxy, j’ai créé un SimpleNetworkWrapper init dans l’event de preInit, ensuite c’est la preInit du proxy et le CommonNetworkHandler s’init(c’est une classe classe où j’enregistre des packets) :@SidedProxy(clientSide = References.CLIENT_PROXY, serverSide = References.SERVER_PROXY) public static ExaCommonProxy proxy; public static SimpleNetworkWrapper NETWORK; @EventHandler public void preInit(FMLPreInitializationEvent event) { NETWORK = NetworkRegistry.INSTANCE.newSimpleChannel(References.MODID); proxy.preInit(); CommonNetworkHandler.init(); }Le CommonNetworkHandler :
public class CommonNetworkHandler { public static void init() { ExaMod.NETWORK.registerMessage(PacketExacarb.PacketExacarbHandler.class, PacketExacarb.class, 1, Side.CLIENT); ExaMod.NETWORK.registerMessage(CPacketMessage.CPacketMessageHandler.class, CPacketMessage.class, 3, Side.CLIENT); ExaMod.NETWORK.registerMessage(CPacketOpenGui.CPacketOpenGuiHandler.class, CPacketOpenGui.class, 5, Side.CLIENT); ExaMod.NETWORK.registerMessage(CPacketOpenGuiGuilds.CPacketOpenGuiGuildsHandler.class,CPacketOpenGuiGuilds.class, 9, Side.CLIENT); ExaMod.NETWORK.registerMessage(PacketSpell.PacketSpellHandler.class, PacketSpell.class, 0, Side.SERVER); } }Le ClientNetworkHandler(la classe des packets destinés au serveur seulement) :
public class ClientNetworkHandler { public static void init() { ExaMod.NETWORK.registerMessage(SPacketMessage.SPacketMessageHandler.class, SPacketMessage.class, 4, Side.SERVER); ExaMod.NETWORK.registerMessage(SPacketShopBuy.SPacketShopBuyHandler.class, SPacketShopBuy.class, 6, Side.SERVER); ExaMod.NETWORK.registerMessage(SPacketShopSell.SPacketShopSellHandler.class, SPacketShopSell.class, 7, Side.SERVER); ExaMod.NETWORK.registerMessage(SPacketShopNumberItem.SPacketShopNumberItemHandler.class, SPacketShopNumberItem.class, 8, Side.SERVER); } }Pourrez vous m’aidez svp ?

Bonsoir,
Ce tutoriel est valide pour la 1.12.2 : https://www.minecraftforgefrance.fr/topic/1000/1-7-2-le-network
Tes paquets doivent toujours être sur les deux sides, il n’y a aucune raison d’avoir des paquets “serveur uniquement” (à la limiter, c’est l’handler du paquet qui va être exécuté que d’un côté, mais le code du paquet doit être sur les deux, car le client doit savoir comment sérialiser le contenu du paquet)
-
@robin4002 d’accord merci, où je devrais init chaque networkHandler ? Dans le CommonProxy tous les deux ? La classe principale ou le client proxy/server proxy ?
-
Tu ne devrais avoir qu’un seul network handler, qui est initialisé dans ou depuis la classe principale.

@robin4002 c’est quand même étrange que quand je lance mon serveur local (Mohist) j’ai un crash au niveau de certains packets(ici un packet qui ouvre un gui lorsqu’il est reçu par le client) :

Il faut mettre un
SideOnly(Side.CLIENT)au dessus de la fonction onMessage de ton handler, dans le cas des paquets envoyé au client. -
Merci beaucoup ^^ le problème est résolu !
