Résolu Est-il Op?

[DiabolicaTrix]

Bonjour,

Donc j’ai commencé dans la shoutbox et je fini ici. J’ai un gui qui s’ouvre quand on vise un joueur et qu’on appuie sur la touche définie par le joueur.

Je voudrais que ce gui change si le joueur est OP, mais je n’ai pas trouvé la fonction, du moins Blackout m’a donné ça: MinecraftServer.getServer().getConfigurationManager().func_152596_g(((EntityPlayer)sender).getGameProfile())

Mais puisque je n’utilise pas une commande pour ouvrir le gui, je n’ai pas de “sender” .

[RedRelay]

La vérification des permissions et de la visée se fait toujours coté serveur.
Tu dois donc intercepter ces événements coté serveur, vérifier que le joueur est OP et si c’est le cas, lui envoyer un paquet avec les données que tu veux afficher dans le GUI.

Coté client, dès que tu reçois le paquet, tu ouvre le GUI OP avec les données du paquet.

[DiabolicaTrix]

Pour la visée je n’ai aucunement eu recours aux paquets, sinon pour le reste je ne vois pas trop comment je pourrais faire ça.

Edit: je n’avais pas lu ton message dans la shoutbox, je vais essayer quelque chose.

[RedRelay]

Si tu calcules la visé coté client, n’importe quel cheater pourra rendre ton mods unfair.
Je t’invite a lire ce tutoriel sur le network, il est valable pour les versions supérieures ou égales a la 1.7.2
http://www.minecraftforgefrance.fr/showthread.php?tid=1118

La détection des touches se fait coté client, donc tu va devoir envoyé un paquet au serveur lorsque le client appuie sur cette touche. Lorsque le serveur reçoit le paquet, il vérifie la visé et le statut du joueur (Op ou non), en fonction de quoi il envoie u paquet au client. Lorsque le client reçoit le paquet, il ouvre le GUI et affiche les données du paquet.

Je ne suis pas sur de comprendre ce que le cheat a à voir avec ça:

public void onKeyInput(KeyInputEvent event) {
if (ClientProxy.overMouse.isPressed()) {
if (Minecraft.getMinecraft().objectMouseOver.entityHit instanceof EntityLiving) {
Minecraft.getMinecraft().displayGuiScreen(new GuiMouseOver());
}
}
}

@‘DiabolicaTrix’:

Je ne suis pas sur de comprendre ce que le cheat a à voir avec ça:

public void onKeyInput(KeyInputEvent event) {
if (ClientProxy.overMouse.isPressed()) {
if (Minecraft.getMinecraft().objectMouseOver.entityHit instanceof EntityLiving) {
Minecraft.getMinecraft().displayGuiScreen(new GuiMouseOver());
}
}
}

Qu’est ce qui m’empêche de faire un mod avec le code suivant :

​ public void onKeyInput(KeyInputEvent event) {
if (ClientProxy.overMouse.isPressed()) {
Minecraft.getMinecraft().displayGuiScreen(new GuiMouseOver());
}
}

Comme ça, je n’ai pas besoin de voir l’entité pour afficher ton GUI.
Après ça dépend ce que tu affiches dans ton GUI en réalité.
Tu veux afficher quoi exactement ?

[DiabolicaTrix]

J’affiche un menu qui offre des options d’interaction du genre: trade.

[RedRelay]

D’accord, si c’est uniquement un menu d’option et si la visé n’est pas un élement clé du gameplay mais juste un élément ergonomique, tu n’est pas obliger de passer par une vérification de la visé coté serveur.
Par contre, tu dois passer par le serveur pour savoir si le joueur est OP ou non, car ces informations sont stockées coté serveur.
Donc tu va forcément devoir passer par des paquets, je ne pense pas qu’il existe une fonction coté client pour savoir si un joueur est OP ou non.

N’oublis pas de prendre en compte dans la suite du développement de ton mod qu’un joueur qui a ton GUI d’ouvert n’est pas forcément OP et peut se trouver a l’autre bout du monde minecraft.

[robin4002]

Tu peux aussi utiliser MinecraftServer.getServer().getConfigurationManager().canSendCommands(player.getGameProfile());

Par contre en effet ce genre ce vérification se fond côté serveur obligatoirement. Donc il faut deux paquets, un que le client envoie au serveur, dans l’action de ce paquet tu vérifies que le joueur est op, si oui dans le return tu mets ton deuxième paquet qui va être envoyé au client sinon tu mets null. Et dans l’action du second paquet tu mets le code pour ouvrir le gui.

[DiabolicaTrix]

@Blackout mais puisque c’est un gui d’interaction… même si il l’ouvre à distance il n’aura sélectionné personne…

@robin4002 ok j’vais voir ça elle fonction comme l’autre fonction?

[robin4002]

C’est un boolean donc tu peux le mettre directement dans un if.

public T4EventHandler eh;
ça c’est bon pour causer un npe.
Ce n’est pas comme ça que tu dois faire, tu dois renvoyer un paquet réponse.
Et le crash que tu nous as envoyé n’a aucun rapport avec ton code, c’est le lib openAL (pour le son) qui crash.

[RedRelay]

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.

[DiabolicaTrix]

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 ibxm.Player;
import net.minecraft.client.Minecraft;
import net.minecraft.client.entity.EntityClientPlayerMP;

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,>

[SCAREX]

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.

[DiabolicaTrix]

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.

[RedRelay]

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,>
