Est-il Op?
-
La dernière fois que j’ai eu cette erreur “Failed to write core dump” c’est parce que je n’allouer pas assez de mémoire a Java au démarrage. Mais comme l’a dit Robin, ça n’a rien a voir avec ton mod.
Tes attributs dans ton packet handler ne servent à rien.
Tu manques d’optimisation.
Je pense que tu n’as pas compris la séparation Client/Server de Minecraft ni le fonctionnement des paquets.Suit mon tuto étape par étape, je vais te guider si tu veux.
Commence par envoyer un simple paquet du client vers le serveur qui lui dit : “Je veux savoir si je suis op”.
Ce paquet n’a pas besoin de contenir des informations.
Met juste un System.out.println(“Paquet reçu”) lorsque le serveur reçoit ce paquet.Post ton code, je t’explique la suite après. On va faire étape par étape.
-
Pour le crash j’avais bien vu que ca n’était pas un crash normal mais bon.
Donc j’ai fait comme tu as dit: j’ai suivi le tutoriel et ça fonctionne(je println quand je reçois le packet)
Mon code:
package diabolicatrix.base; 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 PacketOp implements IMessage { @Override public void fromBytes(ByteBuf buf) {} @Override public void toBytes(ByteBuf buf) {} public static class Handler implements IMessageHandler <packetop, imessage="">{ @Override public IMessage onMessage(PacketOp message, MessageContext ctx) { System.out.println("Message Reçu"); return null; } } }Le event handle:
package diabolicatrix.base; import java.util.Iterator; import cpw.mods.fml.common.eventhandler.EventPriority; import cpw.mods.fml.common.eventhandler.SubscribeEvent; import cpw.mods.fml.common.gameevent.InputEvent.KeyInputEvent; import cpw.mods.fml.relauncher.Side; import cpw.mods.fml.relauncher.SideOnly; import diabolicatrix.base.proxy.ClientProxy; import diabolicatrix.base.Base; import ibxm.Player; import net.minecraft.client.Minecraft; import net.minecraft.client.entity.EntityClientPlayerMP; import net.minecraft.client.entity.EntityOtherPlayerMP; import net.minecraft.client.gui.FontRenderer; import net.minecraft.command.ICommandSender; import net.minecraft.entity.EntityLiving; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.entity.player.EntityPlayerMP; import net.minecraft.client.gui.GuiLabel; import net.minecraft.client.gui.GuiScreen; import net.minecraft.server.MinecraftServer; import net.minecraft.server.management.ServerConfigurationManager; import net.minecraft.server.management.UserListOpsEntry; import net.minecraft.world.World; import net.minecraftforge.client.event.RenderGameOverlayEvent; import net.minecraftforge.client.event.RenderGameOverlayEvent.ElementType; public class T4EventHandler { private MinecraftServer mcs; private Minecraft mc; @SubscribeEvent @SideOnly(Side.CLIENT) public void onKeyInput(KeyInputEvent event) { if (ClientProxy.overMouse.isPressed()) { if (Minecraft.getMinecraft().objectMouseOver.entityHit instanceof EntityLiving) { Base.instance.network.sendToServer(new PacketOp()); //Minecraft.getMinecraft().displayGuiScreen(new GuiMouseOver()); } } } }Mon main:
network = NetworkRegistry.INSTANCE.newSimpleChannel("T4Channel"); network.registerMessage(PacketOp.Handler.class, PacketOp.class, 0, Side.SERVER);PS: je crois que j’ai signalé ton message, je cherchais le + :P</packetop,>
-
Il te reste juste à renvoyer au client un autre paquet contenant un booléen pour savoir si oui ou non le joueur est op. Mais je te conseille plutôt d’envoyer des informations qui exécuteront la tâche voulut si le joueur est op. Car c’est très simple ensuite de cheater avec ton mod si t’utilises les paquet pour savoir si le joueur est op.
-
Donc, mon nouveau code:
package diabolicatrix.base; 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; import net.minecraft.client.Minecraft; import net.minecraft.entity.player.EntityPlayerMP; import net.minecraft.server.MinecraftServer; public class PacketOp implements IMessage { @Override public void fromBytes(ByteBuf buf) {} @Override public void toBytes(ByteBuf buf) {} public static class Handler implements IMessageHandler <packetop, imessage="">{ private boolean isOp; @Override public IMessage onMessage(PacketOp message, MessageContext ctx) { EntityPlayerMP player = ctx.getServerHandler().playerEntity; System.out.println("Message Reçu"); if(MinecraftServer.getServer().getConfigurationManager().func_152596_g(player.getGameProfile())) { System.out.println("op"); Minecraft.getMinecraft().displayGuiScreen(new GuiMouseOver("OP!!")); } else { System.out.println("player"); Minecraft.getMinecraft().displayGuiScreen(new GuiMouseOver("Player!!")); } return null; } } }Mon client est parfait si le allow cheats est à off, ça affiche player sinon ça affiche op.
Mon server crash et je ne comprend pas…

La classe Minecraft n’existe pas côté client.
Tu dois faire comme ça :@Override public IMessage onMessage(PacketOp message, MessageContext ctx) { EntityPlayerMP player = ctx.getServerHandler().playerEntity; System.out.println("Message Reçu"); if(MinecraftServer.getServer().getConfigurationManager().func_152596_g(player.getGameProfile())) { System.out.println("op"); return new PacketOpenAdminGui("OP!!"); } else { System.out.println("player"); return new PacketOpenAdminGui("Player!!"); } return null; }Ensuite tu créé une classe PacketOpenAdminGui dans laquelle tu fais passer la variable string et dans le handle (qui sera donc côté client cette fois) tu fais l’action du openGui.
-
Ton premier code est correct.
Juste le nom de paquet qui est a changer pour éviter les confusion.
Le premier paquet que tu envoie sert a dire au serveur que tu souhaite ouvrir un GUI mais qu’il te faut plus d’information. Donc un bon nom de paquet serait par exemple “PacketAskForGui” ou un truc du genre.Coté serveur, le handler reçoit le paquet.
La mission du handler ici, c’est de répondre au client.
Donc le handler doit vérifier que le joueur est OP, et lui retourner un paquet avec cette information.
Ta classe Handler implémente IMessageHandler avec 2 types générique <laclassdupacketreçu, laclassdupacketrenvoié=“”>Donc dans ton Handler il faut que tu remplace IMessage par la class d’un nouveau paquet.
On appellera cette classe PacketOpenGui mais le nom n’a pas d’importance tant que ça reste logique.
C’est la ou tu dois avec un attribut boolean isOp, c’est dans ton PacketOpenGui.Donc dans le Handler, tu crées une nouvelle instance de ton PacketOpenGui et au lieu de faire un return null, tu retournes ton objet PacketOpenGui.
Assure toi d’avoir bien enregistré le packet avec network.registerMessage();
Incrémente le discriminant (l’id du packet) de 1 et change la side, puisque cette fois ci c’est le client qui reçoit le packet.
Donc Side.Client.Dans ton PacketOpenGui.Handler tu vérifies le contenue de ton PacketOpenGui, et tu ouvre le GUI que tu veux en conséquence.</laclassdupacketreçu,>

Il te manque un constructeur vide dans la classe PacketOpenPlayerMenu. Pour tous les paquets il faut toujours un constructeur vide.
Ajoutes :
public PacketOpenPlayerMenu() {
}
Et ta variable isOp ne devrait pas être static, dans le handler tu dois utiliser message.isOp au lieu de isOp. -
ça ne crash plus mais j’ai aucune réponse comme si le packetop ne recoit plus le packet
-
Mets des System.out.println(“blabla”); par-ci par là pour regarder si ça s’exécute ou pas.
-
Ma touche est détectée mais le packet n’est pas reçu
-
Tu as bien enregistré les paquets ?
-
Ouais
-
Envoi classe principale (celle avec le network), la classe du paquet et l’envoi du paquet.
-
J’envoie demain, je n’ai pas accès à mon ordi c’est pour ça que je ne l’ai pas encore donné
-
Dans ton PacketOpenPlayerMenu, les méthodes fromBytes(ByteBuf buf) et toBytes(ByteBuf buf) ne doivent pas être vide.
Relis le tutoriel.
Pourquoi as-tu utilisé static pour ton boolean isOp ? -
C’était pas volontaire, c’est eclipse qui me l’avait proposé, je l’ai enlevé après. Sinon, je de nouveau accès à mon ordi j’édit dans 2 min pour les codes.

PS: qu’est-ce que j’utilise dans le fromByte?

Çà veut dire que t’as essayé d’appeler la valeur de façon statique. Or tu dois avoir un booléen par joueur
-
Ouais, pour le static, ça va mais pour les codes, j’ai edit mon message précédent, pour le formbyte et tobyte qu’est-ce que je dois mettre pour un boolean?
