Résolu Encore problème onUpdate

[SCAREX]

Tu ne dois pas avoir de variables statiques dans ton paquet. Et pourquoi invoquer pleins de constructeurs s’ils ne sont pas tous utilisés ?

Pas sa mon problème, c’est que j’ai un problème avec le !world.remote et le ClientProxy.keybind … j’ai un conflit client / serveur.
Du coup on m’a dis de faire un packet pour le keybind

Mais je dois mettre quoi dans se packet ? juste le ClientProxy.key… dans la fonction onmessagage ?

Il y a plusieurs problèmes :
 D’abord, dans ton packet, la variable “i” est static or elle ne doit pas l’être.
 Ensuite dans la class de ton item, la ou tu vérifie sur quelle touche on click pour ensuite envoyer une flèche : il faut utiliser des “else if” au lieux de “if” car sinon, si plusieurs conditions sont validés, alors ça invoque plusieurs flèches. De plus, il ne faut pas mettre “&& !world.isRemote” car tu vérifie les touches coté client. (au passage, il manque quelques vérifications de timer)

Salut,
Alors pour le i ok pour les else if c’est fait et si je met pas les && !world.isRemote sa me lance deux flèches une normale et une en feu (pour le sort de feu) et cela a chaque sort sauf pour les 5 flèches car c’est pas avec l’action d’un touche donc pas côté client .

[LeBossMax2]

Oups, j’avais pas pensais à ça… Je pence que le plus simple ce serais d’envoyer aussi la flèche normal et les 5 flèches avec le packet des flèches en mettant bien des “world.isRemote” pour que le serveur ne s’envoie pas des packet à lui même.

Edit : tu devrais aussi gérer les timer coté serveur dans le “onMessage” du packet.

[Gabs]

Je crois que tu n’as toujours pas compris c’est sûrement de ma faute on me dit de pas assez détailler et ils ont raison alors je vais essayer de t’expliquer.

En gros se que je cherche à faire tu as du comprendre ça au moins x):

• Différente flèches sur le même arc activable avec différente touches avec un timer pour ne pas spam les sorts.

Mon problème:

• En gros le soucis c’est que vus que la flèche doit êtres lancé côté serveur et que j’active mes sorts avec des touches côté client tu comprends bien que serveur et client n’est pas trop compatible…
• Du coup moi se que je veux c’est donc lancé la flèche côté serveur et en même temps pouvoir activé le sort avec une touche (on m’a dit que c’était possible avec un packet, mais je vois pas du tout quoi mettre dedans appart juste le Clientproxy.ketbind… dans la fonction onMesssage j’ai pas essayer perso) .

Quand tu dis: tu devrais aussi gérer les timer coté serveur dans le “onMessage” du packet.

Tu parle des temps de recharge de mes sort logiquement si oui je peux faire comment pour les timers avec des int timer ? ensuite if (timer > 0) timer–; un truc du genre ?

[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 ?

[AymericRed]

Il faudrait aussi un packet pour la changer.

Euhhhhhh c’est à dire ?
Je sais pas c’est quoi le métadata ^^

[SCAREX]

Le metadata est un nombre (par défaut à 0) qui est présent sur tous les items et les blocks ce qui permet de créer plusieurs variantes d’un item ou d’un bloc, exemples : la laine n’a qu’un seul bloc avec plusieurs métadatas, les items qui s’usent utilisent les métadatas, les blocs qui ont une orientation ont des métadatas différents, etc.

Ahhh ok je vois .
Mais comment l’utilisé ?
Si vous avez des tutos ou quoi je suis preneur car la ^^ .

[SCAREX]

stack.metadata

[robin4002]

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

[SCAREX]

En revanche tu peux toujours utiliser les nbt

[Gabs]

Donc si j’ai bien compris il faut que je changer les metadata de la touche ? c’est bien ça ?
Mais je vois pas du tout comment faire en fait …

[SCAREX]

Nan, il faut changer les tags nbt de l’item lorsque tu appuies sur une touche

[Gabs]

@‘SCAREX’:

Ah je vois le truc je crois.

J’ai essayer ça, me taper pas s’il vous plait mais je crois que je suis pas bien loin x):

Proxy:

 
 @SubscribeEvent
   public void onEvent2(KeyInputEvent event)
   {
       if(keyBindSortG1.isPressed())
       {
           keyTestTyped2();
       }
   }
 
   private void keyTestTyped2()
   {
    ItemStack stack = new ItemStack(LegacyMod.FlameBow);
    NBTTagCompound nbt = new NBTTagCompound();
    stack.getTagCompound().setTag("key", nbt);
 
   }
 

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);
           }

Forcément ça crash ça vient du private void keyTestTyped2() à mon avis.

[robin4002]

1. tu créé un item stack de null part
2. sans le rapport de crash on ne peut pas te dire d’où vient le souci.
