Problème d'handler



  • Bonjour/Bonsoir,
    J'ai un problème avec mon handler. Quand je crée un nouveau monde, j’apparais sans crash, j'édite les données de mon ExtendedEntityProperties, le serveur et le client sont synchronisés. Mais quand je quitte le jeu et que je relance la map, ou que je quitte simplement la map et que je la relance, et bien je crash avec un NPE. J'ai beau chercher je ne trouve pas la raison de ce NPE. C'est pourquoi je vous demande vôtre aide.

    Voici les logs d'erreur:

    Donc déjà merci d'avoir lu ce sujet et désolé si vous perdez du temps pour une erreur de débutant.</packetmoney,>


  • Administrateurs

    java.lang.NullPointerException
    at tarael.extendedentity.ExtendedEntityPropTuto.get(ExtendedEntityPropTuto.java:38) ~[ExtendedEntityPropTuto.class:?]

    Ton ExtendedEntityPropTuto est null. Vérifies que ta classe MoneyEventHandler soit bien enregistré comme classe d'event.



  • Ma classe MoneyEventHandler est enregistrée dans l'init comme ça: MinecraftForge.EVENT_BUS.register(new MoneyEventHandler());


  • Administrateurs

    Dans ce cas tu ne devrais pas avoir un npe. C'est étrange. Vérifies peut-être que Minecraft.getMinecraft().thePlayer n'est pas null à l'arrivé du paquet.



  • J'ai vu que le NPE était causé par ceci dans ma classe de l'extendedentityprop :

    public static final ExtendedEntityPropTuto get(EntityPlayer player) 
    {
    return (ExtendedEntityPropTuto) player.getExtendedProperties(EXT_PROP_NAME);
    }
    

    et par ceci dans l'handler du packet

    else if(ctx.netHandler instanceof NetHandlerPlayClient)
           {     
            EntityPlayerSP player = Minecraft.getMinecraft().thePlayer;
            ExtendedEntityPropTuto dat = ExtendedEntityPropTuto.get(player);
               dat.update(message.money, message.maxMoney);
           }
    

    Ce serait à cause de la façon dont je récupère le joueur pour le client  ?

    Et désolé si je met du temps à répondre à vos aides, je ne suis pas très dispo pendant la semaine  :s


  • Administrateurs

    Normalement ça devrait fonctionner. C'est peut-être le fait d'envoyer le paquet tout de suite à la connexion qui cause problème.
    Dans le paquet ajoute :
    System.out.println(Minecraft.getMinecraft().thePlayer);
    S'il affiche null c'est bien que le joueur est null.



  • Quand je recrée une map j'obtiens ça:

    [Netty Local Client IO #0/INFO] [STDOUT]: [tarael.packet.PacketMoney$Handler:onMessage:85]: EntityPlayerSP['Wassangota'/207, l='MpServer', x=8,50, y=65,00, z=8,50]
    [18:46:13] [Netty Local Client IO #0/INFO] [STDOUT]: [tarael.packet.PacketMoney$Handler:onMessage:85]: EntityPlayerSP['Wassangota'/207, l='MpServer', x=8,50, y=65,00, z=8,50]
    

    Et quand je la relance je ne l'ai plus, seulement les logs de crash. J'ai mis le println au mauvais endroit dans mon classe ?


  • Administrateurs

    En effet, met le print au début de la condition.



  • Au début dans le "else if" j'obtiens ça maintenant dans le crash

    [Netty Local Client IO #0/INFO] [STDOUT]: [tarael.packet.PacketMoney$Handler:onMessage:82]: null
    

    donc cette ligne ```java
    System.out.println(Minecraft.getMinecraft().thePlayer);


  • Administrateurs

    Oui donc c'est bien le joueur qui est null.
    Donc envoyer un paquet dès la connexion n'est pas une bonne idée.



  • Donc si j'ai bien compris pour envoyer le paquet il ne faut pas que je passe par EntityJoinWorldEvent mais par autre chose dans l'event handler ?


  • Administrateurs

    Regardes avec PlayerEvent.PlayerLogginEvent (par contre c'est un event de fml).



  • Oui ça marche maintenant je peux relancer mon monde en solo et en multi sans crash. Mais quand je meurs je perd mes données. Je sauvegarde mal les données dans LivingDeathEvent ?


  • Administrateurs

    Mets un System.out.println("quelque chose"); dans saveNBTData et loadNBTData pour vérifier que les fonctions sont appelés.



  • Alors quand je rejoins le monde le message que j'ai mis dans le loadNBTData apparaît bien dans la console et quand je meurt celui du saveNBTData aussi. Les fonction sont donc bien appelées mais alors pourquoi alors je n'obtiens pas la valeur de mon argent ?


  • Administrateurs

    Aucune idée x)
    Renvoies ton code actuel ?



  • Voila le code de mon event handler :

  • Regarde si tu appelles les variables côté serveur ou client déjà, si c'est serveur et que ça ne marche pas, le problème vient de ton EEP, sinon c'est surement un problème de synchronisation



  • Comment ça ? Tu veux que je regarde si dans le onMessage j'envoie les données vers le serveur et le client ?



  • System.out.println() affichera la side d'où la fonction est appelé dans la console.
