Encore problème onUpdate

Gabs

@‘robin4002’:

Déjà le stack obtiens-le depuis l’inventaire du joueur au lieu de créer une nouvelle instance sinon ça ne fonctionnera pas.
Ensuite il faut faire stack.setTagCompound(new NBTTagCompound()); avant de le get.

J’ai fais ça:

public static class Handler implements IMessageHandler <packetkey, imessage="">{

   public IMessage onMessage(PacketKey message, MessageContext ctx) {

    ItemStack stack = ctx.getServerHandler().playerEntity.inventory.getItemStack();
    stack.setTagCompound(new NBTTagCompound());
    NBTTagCompound nbt = (NBTTagCompound) stack.getTagCompound().getTag("key");
    stack.getTagCompound().setTag("key", nbt);
    return null;
       }
   }

Crash:

Rajoute un null check pour ta variable stack, avant le setTagCompound

robin4002

Si tu n’avais pas d’item en main c’est normal que cela crash (suffit de faire ce que plaigon t’a dis).
Si tu avais un item en main, le crash vient surement de la ligne d’après, ce que tu fais n’a pas de sens.

Je te conseille aussi de regarder la dernière vidéo de la chaine de mff, car rester bloquer sur un simple NPE ça ne devrait pas arriver …

J’avais un item dans la main oui, j’ai r’ajouter un null check pour évité le crash sans item.
Maintenant c’est le NBTTagCompound nbt = (NBTTagCompound) stack.getTagCompound().getTag(“key”); qui pose soucis .
Je sais que se que j’ai fais n’a pas de sens mais je vois pas comment le récupéré le nbt.

stack.getTagCompound() quel est le problème ?

mais what?
tien:

J’ai fais ça plus de crash:

Mais bon ça me lance une flèche normale au lieux d’une flèche en feu.

[21:25:20] [Server thread/INFO] [STDOUT]: [net.legacymod.items.FlameBow:onPlayerStoppedUsing:142]: flèche normale

Normalement ça doit exécute ça:

           {
            LegacyMod.network.sendToServer(new PacketArrow(f * 2.0F, 3));

Tu as le packetKey et le packetarrow ^^

SCAREX

Oui mais à quoi sert le PacketArrow alors ?

D’ailleurs je ne comprends pas ce que tu veux faire avec ce code :

if(stack != null){
stack.setTagCompound(new NBTTagCompound()); // Tu supprimes tous les tags de l'item
NBTTagCompound nbt = (NBTTagCompound) stack.getTagCompound(); // Ensuite tu récupères les tags (qui sont nuls désormais)
stack.getTagCompound().setTag("key", nbt); // et tu mets les tags de l'item (qui sont nuls) dans un tag "key" dans l'item
}

[font=Ubuntu, sans-serifCitation de SCAREX: Est-ce que ce ne serai pas plus simple de modifier le metadata lorsqu’on appuie sur une touche et ensuite récupérer le metadata afin de savoir quelle sorte de flèche tirer ?]

robin4002

@‘robin4002’:

Avec un outil ce n’est pas bon car le metadata est déjà utilisé pour l’usure de l’item.

Au lieu de faire un setTag mets plutôt un integer qui correspond au mode de l’arc.
