Le tag nbt est nul, mais tu ne peux pas faire comme ça car sinon il y aura un problème de synchronisation entre le client et le serveur, il te faut envoyer un paquet au serveur et c’est lui qui ajoutera les nbt puisque c’est de ce côté que vont être tirées les flèches.

D’accord alors j’ai fais ça:
Packet (enregistrer côté client):
package net.legacymod.packets; import io.netty.buffer.ByteBuf; import net.legacymod.LegacyMod; import net.legacymod.gui.ClassesGUI; import net.minecraft.client.Minecraft; import net.minecraft.item.ItemStack; import net.minecraft.nbt.NBTTagCompound; import cpw.mods.fml.common.network.simpleimpl.IMessage; import cpw.mods.fml.common.network.simpleimpl.IMessageHandler; import cpw.mods.fml.common.network.simpleimpl.MessageContext; public class PacketKey implements IMessage { public PacketKey(){ } @Override public void fromBytes(ByteBuf buf) { } @Override public void toBytes(ByteBuf buf) { } public static class Handler implements IMessageHandler <packetkey, imessage="">{ public IMessage onMessage(PacketKey message, MessageContext ctx) { ItemStack stack = new ItemStack(LegacyMod.FlameBow); NBTTagCompound nbt = (NBTTagCompound) stack.getTagCompound().getTag("key"); stack.getTagCompound().setTag("key", nbt); return null; } } }
Proxy:
@SubscribeEvent public void onEvent2(KeyInputEvent event) { if(keyBindSortG1.isPressed()) { keyTestTyped2(); } } private void keyTestTyped2() { LegacyMod.network.sendToServer(new PacketKey()); }
FlameBow (classe de l’arc):
else if (!world.isRemote && stack.getTagCompound().hasKey("key")) { LegacyMod.network.sendToServer(new PacketArrow(f * 2.0F, 3)); System.out.println("flèche en feu"); //stack.getTagCompound().setInteger("timer2", 0); }
J’ai pas de crash, mais le truc c’est que ça me lance une flèche normale quand j’appuie sur la touche au lieux de la flèche en feu.</packetkey,>
Tu tes mélange complètement les pinceaux.
!world.isRemote = côté serveur.
Pourquoi tu envoies un paquet vers le serveur si tu es déjà côté serveur ?
Ensuite comme le paquet va du client au serveur, le paquet doit être enregistré avec Side.SERVER et non client.
Et pour finir, tu as de-nouveau un item stack qui sort de null part, cette fois-ci dans l’handler de ton paquet :
ItemStack stack = new ItemStack(LegacyMod.FlameBow);

Car Scarex m’a dis d’envoyer le packet côté serveur.

@‘robin4002’:
Et pour finir, tu as de-nouveau un item stack qui sort de null part, cette fois-ci dans l’handler de ton paquet :
ItemStack stack = new ItemStack(LegacyMod.FlameBow);
La raison du crash est là.
Ton item stack que tu sors de null part n’a pas de tag nbt.
Donc forcement npe.

Comment je lui ajoute des nbt ?
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; } }

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

J’ai essayer mais j’ai eu un crash je le refais je te glisse le crash 30 secondes

ligne 40: NBTTagCompound nbt = (NBTTagCompound) stack.getTagCompound();
Ton ItemStack est null, envoi le code
@‘SCAREX’:
Ton ItemStack est null, envoi le code
Encore ?!
mais what?
tien:
public static class Handler implements IMessageHandler <packetkey, imessage="">{ public IMessage onMessage(PacketKey message, MessageContext ctx) { ItemStack stack = ctx.getServerHandler().playerEntity.inventory.getItemStack(); if(stack != null){ stack.setTagCompound(new NBTTagCompound()); } NBTTagCompound nbt = (NBTTagCompound) stack.getTagCompound(); stack.getTagCompound().setTag("key", nbt); return null; } }
edit: my bad ^^
J’ai fais ça plus de crash:
public static class Handler implements IMessageHandler <packetkey, imessage="">{ public IMessage onMessage(PacketKey message, MessageContext ctx) { ItemStack stack = ctx.getServerHandler().playerEntity.inventory.getItemStack(); if(stack != null){ stack.setTagCompound(new NBTTagCompound()); NBTTagCompound nbt = (NBTTagCompound) stack.getTagCompound(); stack.getTagCompound().setTag("key", nbt); } return null; } }
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:
else if (!world.isRemote && stack.getTagCompound().hasKey("key")) { LegacyMod.network.sendToServer(new PacketArrow(f * 2.0F, 3)); System.out.println("flèche en feu"); //stack.getTagCompound().setInteger("timer2", 0); } ```</packetkey,></packetkey,>

C’est bien sendToServeur puisque ça va vers le serveur. En revanche y’a un truc que je comprends pas : pourquoi envoyer un PacketKey et me donner la classe PacketArrow ?

Tu as le packetKey et le packetarrow ^^
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 }
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.
