Extended Entity Properties

BlackDrag00n

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

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

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 ?

Dezta

Hallelujah ! Soit béni mon frère ! Ça marche !

Je n’avais déclaré que l’une des 2 catégorie d’event forge, j’ai rajouté celle qui manquait:

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

Merci beaucoup !

robin4002

FMLCommonHandler.instance().bus().register(new EntityEventHandler()); n’est pas nécessaire ici, c’est pour les event de fml, or tu n’as pas d’event fml dans la classe

Dezta

A ok, j’avais inversé les 2, je ne savais pas lequel enlevé, voila c’est dit .

mindany2

Salut ,
J’ai toujours un problème avec les Extended Entity Properties, j’ai revu plusieurs fois mon code mais les packets n’ont pas l’air de se transmettre peut importe ce que je fais les données restent toujours à 0
Si vous avez une petite idée ^^ :
PacketSonic :

 public class PacketSonic
extends FFMTPacket
{
 
public int Descendre;
public boolean DoubleJump;
public long Ring;
 
public PacketSonic(){
 
}
 
public PacketSonic(int Descendre, boolean DoubleJump, long Ring){
this.Descendre = Descendre;
this.DoubleJump = DoubleJump;
this.Ring = Ring;
}

Bonjour,
Alors voilà mon problème : je n’arrive pas à synchroniser le server et le client pour mon ExtendedProperties : sur le client la propriété se remet à 0 dès qu’on charge le monde, et par contre sur le server pas de soucis ça sauvegarde bien :
