Système de rang

AymericRed

L’idée de BrokenSwing est meilleure, je pense, sachant qu’avec les EEP il sera impossible (enfin difficile, pas impossible) de voir ou modifier son rang si il est déconnecté.

Gabs

Ok donc j’ai fais sa dite moi si c’est pas mal :
Au passage pour le changement de grade en gros je fais avec un gui et des boutons donc je pense que le changement va se faire avec des packets a vous de me dire la meilleure solution.

class:


package net.legacymod.properties;

import java.util.HashMap;
import java.util.UUID;

import net.minecraft.entity.Entity;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;
import net.minecraftforge.common.IExtendedEntityProperties;

public class EnumRank{

HashMap <uuid, enumrank="">rank = new HashMap<uuid, enumrank="">();

private final EntityPlayer player;

public EntityPlayer guerrier;

public EntityPlayer mage;

public EntityPlayer archer;

    public EnumRank(EntityPlayer player)
    {
    this.player = player;

    this.archer = player;

    this.guerrier = player;

    this.mage = player;

    }

}

ps: je suis bloqué genre je voudrais faire une fonction setgrade quelle puisse grade le joueur.</uuid,></uuid,>

robin4002

Tu ne sais pas ce qu’est un enum.

package net.legacymod.properties;

import java.util.HashMap;
import java.util.UUID;

public enum EnumRank
{
GUERRIER,
MAGE,
ARCHER;

public static final HashMap <uuid, enumrank="">RANK = new HashMap<uuid, enumrank="">();
}
```</uuid,></uuid,>

BrokenSwing

Ton Enum :


public enum EnumRank {

GUERRIER,
MAGE,
ARCHER;

}

Après il faut que tu crée la HashMap dans le proxy serveur par exemple :


HashMap <uuid, enumrank="">rank = new HashMap<uuid, enumrank="">();

Quand je joueur se connecte tu lui envoie son rang avec un paquet, et quand il change aussi tu lui envoie avec le même paquet, vu que tu va changer le rang des joueurs via un Gui, effectivement il va falloir envoyer un paquet au serveur lui disant de modifier le rang, entraînant une update du client concerné</uuid,></uuid,>

Gabs

Ok j’ai compris je crois

Yeyvo

Je viens de finir d’apprendre les enum et les hashmap et je vois déjà a quoi il servent t j’en déduit qu’il sont trés utille c’est pour ça que je t’invite à les comprende

Gabs

Donc la j’ai fais se que tu m’as dis j’ai fais mon enum j’ai créer le hashmap dans le serverproxy .
Pas de besoin d’envoyer un packet lors de la connexion car moi le joueur dès que il se connecte ça va lui ouvrir un gui et il aura 3 choix de grade et une fois le grade choisis il pourra pas changer.
Mais le truc c’est que dans mon packet pour passer le joueur par Archer je dois procédé comment ?
EnumRank.ARCHER me met une erreur et de plus je vois pas comment ça peut grade le joueur^^.

BrokenSwing

En gros tu fais un paquet envoyant un String correspondant à ton rang (ex. EnumRank.ARCHER.name())
Puis tu récupère côté serveur l’énumération dans le paquet avec EnumRank.valueOf(le String du paquet) et tu le place dans la HashMap, quand tu veux savoir quel est le rang du joueur tu récupère la valeur dans la HashMap

Gabs

Ok j’ai a peu près compris dis moi si c’est bon par contre quand tu me dis de placer l’énumération dans la hashmap je vois pas se que tu veux dire du coup je te passe se que j’ai fais:

ServerProxy:

import java.util.HashMap;
import java.util.UUID;

import net.legacymod.packets.PacketGuerrier;
import net.legacymod.properties.EnumRank;

public class ServerProxy {

public static final HashMap <uuid, enumrank="">RANK = new HashMap<uuid, enumrank="">();

public ServerProxy(){
EnumRank.valueOf(PacketGuerrier.name);
}

}

Packet:


public class PacketGuerrier implements IMessage {

private boolean police;
public static Minecraft mc;
public static String name;
public PacketGuerrier(){

}
public PacketGuerrier(boolean police, String name, int x, int y, int z){
this.police = police;
this.name = name;
}

@Override
public void fromBytes(ByteBuf buf) {
this.police = buf.readBoolean();
this.name = buf.toString();

}

@Override
public void toBytes(ByteBuf buf) {
buf.writeBoolean(this.police);
this.name = buf.toString();

}

public static class Handler implements IMessageHandler <packetguerrier, imessage="">{
   public IMessage onMessage(PacketGuerrier message, MessageContext ctx) {

        EntityPlayer player = mc.thePlayer;
        EnumRank.GUERRIER.name();
        System.out.println("Vous êtes guerrier!");
        return message;
       }
   }

}

```</packetguerrier,></uuid,></uuid,>

BrokenSwing

Non, c’est pas du tout ça, tu ne sais pas utiliser les paquets, d’autant plus que tu n’utilises pas ta HashMap. Je te conseille de bien lire le tutoriel sur les paquets et lire aussi le sujet sur comment marche minecraft, parce que là, tu va crash et en plus ça va rien faire

Gabs

C’est mieux ?


public class PacketGuerrier implements IMessage {

public static String name;

public PacketGuerrier(){

}
public PacketGuerrier(String name){
this.name = name;
}

@Override
public void fromBytes(ByteBuf buf) {
this.name = ByteBufUtils.readUTF8String(buf);

}

@Override
public void toBytes(ByteBuf buf) {
ByteBufUtils.writeUTF8String(buf, name);

}

public static class Handler implements IMessageHandler <packetguerrier, imessage="">{
@Override
   public IMessage onMessage(PacketGuerrier message, MessageContext ctx) {
        EnumRank.GUERRIER.name();
        return message;
       }
   }

```</packetguerrier,>

BrokenSwing

Presque, il faut que dans la fonction onMessage tu ajoutes le rang à la HashMap avec l’UUID du joueur et tu pourra me montrer comment tu as enregistré ton paquets ?

Gabs

Alors
J’ai fais ça:


public class PacketGuerrier implements IMessage {

public static String name;
public static Minecraft mc;

public PacketGuerrier(){

}
public PacketGuerrier(String name){
this.name = name;
}

@Override
public void fromBytes(ByteBuf buf) {
this.name = ByteBufUtils.readUTF8String(buf);

}

@Override
public void toBytes(ByteBuf buf) {
ByteBufUtils.writeUTF8String(buf, name);

}

public static class Handler implements IMessageHandler <packetguerrier, imessage="">{
@Override
   public IMessage onMessage(PacketGuerrier message, MessageContext ctx) {
EntityPlayer player = mc.thePlayer;
        EnumRank.GUERRIER.name();
        ServerProxy.RANK.put(player.getUniqueID(), EnumRank.GUERRIER);
        return message;
       }
   }

}

Le packet est enregistrer côté serveur:

network.registerMessage(PacketGuerrier.Handler.class, PacketGuerrier.class, 1, Side.SERVER);

Et mon ServerProxy qui a mon avis n’est pas bon:


package net.legacymod.proxy;

import java.util.HashMap;
import java.util.UUID;

import net.legacymod.packets.PacketGuerrier;
import net.legacymod.properties.EnumRank;

public class ServerProxy {

public static final HashMap <uuid, enumrank="">RANK = new HashMap<uuid, enumrank="">();

public ServerProxy(){
EnumRank.valueOf(PacketGuerrier.name);

}

}

```</uuid,></uuid,></packetguerrier,>

BrokenSwing

J’ai la flemme de te faire les bonnes classes, donc je vais essayer de t’expliquer :
Dans ton paquet tu enlève l’attibut static la variable name et tu enlève la variable mc, pour ce qui est du constructeur tu met ça


public PacketGuerrier(){

}

public PacketGuerrier(EnumRank rank) {
this.name = rank.name();
}

dans la fonction onMessage tu met ça


public IMessage onMessage(PacketGuerrier message, MessageContext ctx) {

ServerProxy.RANK.put(ctx.getServerHandler().playerEntity.getUniqueID(), EnumRank.valueOf(message.name));
return null;
}
}

Et tu enlèves ce que tu as mis dans le constructeur de ton ServerProxy

Gabs

Ok j’ai essayer ça mais j’ai eu un crash:

Il faut que tu mette ça :


LegacyMod.network.sendToServer(new PacketGuerrier(EnumRank.LERANG));

Ok merci c’est nickel !

EDIT:

Par contre j’ai un soucis comment je peux faire?
En gros je voudrais faire que une fois que le joueur a choisis sont rang il ne puisse plus changer.

J’ai fais ça:

case 1:
if(ServerProxy.RANK.values() == null){
LegacyMod.network.sendToServer(new PacketGuerrier(EnumRank.GUERRIER));
this.mc.thePlayer.closeScreen();
EntityPlayer player1 = Minecraft.getMinecraft().thePlayer;
ChatComponentText text1 = new ChatComponentText("§7blablabla: " + ServerProxy.RANK.values() +" §8!");
player1.addChatComponentMessage(text1);
}else{
this.mc.thePlayer.closeScreen();
}

Le problème est que quand le joueur n’a pas de grade sa ne return pas null du coup je sais pas comment faire…

BrokenSwing

Il suffit juste que dans la méthode onMessage tu mette ceci :


public IMessage onMessage(PacketGuerrier message, MessageContext ctx) {
if(ServerProxy.RANK.get(ctx.getServerHandler().playerEntity.getUniqueID() == null) {
ServerProxy.RANK.put(ctx.getServerHandler().playerEntity.getUniqueID(), EnumRank.valueOf(message.name));
return null;
}
}
}

Ok c’est bon j’ai trouvé merci
Et pour save comment je peux faire ?
