Extended Entity Properties

J’ai un petit problème, j’utilise

``` mais l'information ne change pas :s
Savez vous d'où viens le problème ?

Normalement c’est bon sauf si je me suis encore gourré

Dans ta classe "ExtendedEntityPropFr " tu indique un packet et des imports suivant :

package lmac.sonic;

import lmac.sonic.packet.PacketSonic;
import lmac.sonic.proxy.CommonProxy;

En théorie sa devrait être :

package fr.lmac;

import fr.lmac.packet.PacketSonic;
import fr.lmac.proxy.CommonProxy;

Si tu essaye de cacher ton projet laisse tomber, je sais que tu prépare un mod “Sonic” avec le système de double saut ^^, donc sa serai bien que l’on passe à ton problème car on tourne en boucle a chaque copie que tu fait et que tu remplace des valeurs, il y a des erreurs différentes :p___Bon j’ai vu que tu as crée ton mod dans la section en développement, maintenant ton problème est reglé ou pas ?

Si non peut tu vérifier ces points suivant :

@Mod(modid = "Sonic_Mod", […]

@Instance("Sonic_Mod")

public static final PacketManagerrcModPacketHandler = new PacketManager("lmac.sonic.packet", "Sonic_Mod", "Sonic_Mod");

Et que le “PacketSonic.java” se trouve bien dans ton package “lmac.sonic.packet” ?

mindany2

(24h avant un double post ^^')
Les packages changent rien au problème de tout façon prendre ceux que j’ai mis dans les balises codes ou un autre
Je vais enlevé tout mes post qui ne concerne pas ce problème (où on tournait autour du pot) afin de laisser ce topic propre

Sinon tu as une idée du problème ^^ ?

BlackDrag00n

bah sa change rien au fait qu’on a besoin de voir tes scripts pour voir l’erreur qu’y a pu s’y mettre pour t’aider a la résoudre, car si tu as bien suivi le tuto sa devrait marche (j’ai récemment fait le tuto et j’ai pas eu de problème).

Dans ta méthode :

public void onTickPlayer(TickEvent.PlayerTickEvent event)

Essai de Modifier pas ça :

if(!jumpLast)
{
jumpLast = true;
System.out.println("Jump : TRUE");
System.out.println("Jump Prop : "+ExtendedEntityPropFr.get(mc.thePlayer).DoubleJump);
}
else if(timer > 2)
{
prop.setDoubleJump(true);
jumpLast = false;
System.out.println("Jump : FALSE");
System.out.println("Jump Prop : "+ExtendedEntityPropFr.get(mc.thePlayer).DoubleJump);

}

Cela va permettre d’afficher dans la console si la valeur “jumpLast” est égale à “true” ou “false” et donc de vérifier qu’il voit bien le double saut, l’autre ligne va permettre d’aller récupérer la valeur dans le “ExtendedEntityProp” et de savoir si elle a bien été enregistrer ou non.

mindany2

Avant d’utiliser cette méthode pour l’enregistrement des données ça marchait
Donc effectivement ça ne marche pas, il y a bien false lors du double jump

Jump : FALSE
Jump Prop : false
Jump : TRUE
Jump Prop : false

PS. I know

BlackDrag00n

donc apparemment tu aurais un problème avec le :

prop.setDoubleJump(true);

Tu peux me donner la méthode de “setDoubleJump” dans “ExtendedEntityPropFr.java”

Et juste pour information personnel, tu as placé ou la méthode “onPlayerTick”

mindany2

Tiens

public void setDoubleJump(boolean newDoubleJump) {
this.DoubleJump = newDoubleJump;
this.sync();
}

Dans une classe que j’ai enregistrer avec

FMLCommonHandler.instance().bus().register(new PlayerTracker());
MinecraftForge.EVENT_BUS.register(new PlayerTracker());

``` dans ma classe principale

PS.Je sais que j'ai un problème avec mon set ou ma synchro sinon je serais pas là :p
PS2.Je t'ai déjà donné la classe entière (donc avec le set) dans mes anciens message :D

BlackDrag00n

cela ma l’air correct et ta méthode “sync”, peut tu l’a donner ?

@‘mindany2’:


public class ExtendedEntityPropFr implements IExtendedEntityProperties {

public final static String EXT_PROP_NAME = "ExtPropFr";

}

if (savedData != null) {

}

public boolean getDoubleJump() {
return this.DoubleJump;
}

public void setDoubleJump(boolean newDoubleJump) {
this.DoubleJump = newDoubleJump;
this.sync();
}

}

Voigna ^^

Je ne vois rien d’étrange tout a l’air correct dans le codage.

Après je pense qu’il faut attendre des codeurs un peu plus expérimenter dans le codage minecraft, car moi actuellement je suis bloquer dans le “onPlayerTick” il veut pas me le prendre en compte …

donc je n’en suis pas a ton niveau ou tu cherche à enregistrer les valeurs mais ton problème viens d’ici, je pense au sync() principalement, du au test que l’on a fait avec les string out mais c’est peut être pas ta faute c’est peut être un problème dans le tuto.

Je n’est jamais utiliser cette méthode encore… je découvre

mindany2

Ok j’attendrais que quelqu’un d’autre passe
Niveau onPlayerTick t’a bien mis
" @SideOnly(Side.CLIENT)
@SubscribeEvent"

BlackDrag00n

ouep je suis en train de crée une réponse sur mon poste et je te donne le lien sa sera mieux pour éviter de mélanger les problèmes

Voilà si tu veux jeter un œil au codage où tenter de comprendre mon problème je te donne “le lien” ou j’ai poster mon problème

Bonjour, j’ai suivi le tutoriel a la lettre, et pourtant j’ai une erreur dans la classe du common proxy


public class CommonProxy
{

private static final Map <string, nbttagcompound="">extendedEntityData = new HashMap<string, nbttagcompound="">();

public void registerRender ()
{

System.out.println("Méthode du serveur");

}

public static void storeEntityData(String saveKey, NBTTagCompound savedData) {

extendedEntityData.put(name, compound);
}

public static NBTTagCompound getEntityData(String saveKey) {
return extendedEntityData.remove(name);
}

}

Chez moi j’ai une erreur sur “name” et “compound”. Si je les déclare dans la classe du CommonProxy, le jeu plante quand je fais clic droit avec l’item.
Quelqu’un aurait-il une idée ?</string,></string,>

robin4002

public static void storeEntityData(String name, NBTTagCompound compound)
{
extendedEntityData.put(name, compound);
}

Dezta

Merci beaucoup ! C’était surement une erreur de recopiage (je retape tout a la main pour mémorisé ).
Mais même si j’arrive maintenant a compilé, j’ai un autre crash, lorsque je fait le clic droit avec l’item pour testé.
Voici les logs,mais je ne sais pas quel partie du code il faudrait que je poste.
A priori, ça va vient plutôt de l’item ou de l’extented entity ?

props semble être null, tu n’as pas enregistrés ton custom entity properties ou les event qui le fond.

A oui, enfaite j’avais oublier de créer la classe EventHanddler… ^^ Forcement ça marche un peu moins bien sans.

Par contre, j’ai exactement les même erreurs dans les logs, même ligne, même classe, donc je pence que ça doit venir de autre part. Vu que j’ai fait quelques corrections de méthodes qui mettaient des erreurs partout a cause de la classe Event qui manquait et que j’ai ajouté une jauge de mana, je te repost tousa :

Au passage, comment tu fait pour savoir que props est nul ?

robin4002

Car l’erreur est un NullPointerException, qu’il te donne la ligne et qu’il n’y a pas d’autre objet qui peut être null sur cette ligne.
Tu as enregistrés la classe d’event avec MinecraftForge.EVENT_BUS.register(new EntityEventHandler()) dans ta classe principale ?
