Pleins de problèmes crashs.

Gabs

@‘robin4002’:

rayTrace n’existe pas côté serveur. Voire : https://www.minecraftforgefrance.fr/showthread.php?tid=4009

Et pour ton autre problème, getClientGuiElement doit retourner soit null (pas de gui) soit un GuiScreen.
Toi tu retournes z si ID ne vaut pas 6. Or z est un int. Donc forcement java.lang.ClassCastException

D’accord merci,

Mais c’était l’orsque je faisais un clique droit sur le joueur pour ouvrir mon guiPrison que j’ai eu ce crash.

ça a quand même un rapport le return z; ?

Pour le raytrace j’ai copier coller les fonctions mais j’ai 5 érreurs (c’est au niveau des returns des fonctions) : The method […] is undefined for […]

Décidément sur ce forum y’en a beaucoup qui aiment les fessées (“fessai”).

Remplace toutes les “Vec3.createVectorHelper(player.posX, player.posY, player.posZ)” par “new Vec3(player.posX, player.posY, player.posZ)”

Aie j’avais pas vu la faute ^^

Pour les cev3 du coup c’est bon
mais j’ai toujours le problème avec le:


return player.worldObj.func_147447_a(vec3, vec32, false, false, true);

La fonction existe pas je crois je peux la remplacer par quoi? ou comment réglé le soucis ?

robin4002

La fonction a surement été mappé en 1.8.
Donc elle doit avoir un nom anglais au lieu de func_xxxx

Regardes ce que fais la fonction rayTrace et tu sera par quoi il faut la remplacer.

Ah j’ai trouvé ça: return player.worldObj.rayTraceBlocks(vec3, vec32, false, false, true);

ça a l’air cohérent .

J’essaye je te dis !

Bon j’ai essayer en solo ça à l’air bugger.

Il faut que je sois absolument sur le bloc pour que il se change en bloc propre sinon il me dis action impossible !

Sinon fait le rayTrace normal en client et passes par un paquet. Je pense que ça sera plus simple x)

Gabs

Quelqu’un ?

LeBossMax2

Fait attention à ce que tu fait :

public ItemStack onItemUseFinish(ItemStack stack, World worldIn, EntityPlayer playerIn
{
    if(!worldIn.isRemote) {                                        //Si on est coté serveur
        if(stack != null && stack.getItem() == CSCItems.balai) {
            EntityPlayerMP p = (EntityPlayerMP)playerIn;
            Main.network.[size=large**sendToServer**](new PacketBalai());       //Envoyer le packet au serveur
        }
    }
    return stack;
}

@SideOnly([size=large**Side.CLIENT**]) //Réception du message coté client
@Override
public IMessage onMessage(PacketBalai message, MessageContext ctx) 
{
    …

et enfin

network.registerMessage(PacketBalai.Handler.class, PacketBalai.class, 2, **%(#ff3333)[Side.CLIENT]**); //Message recevable par le client

De plus,le but du packet et de faire le “rayTrace” coté client puis d’envoyer les infos au serveur. Là tu envoi rien au serveur puis tu demande au serveur de faire le “rayTrace”.

Gabs

" Là tu envoi rien au serveur puis tu demande au serveur de faire le “rayTrace”. "

Je comprends pas.

Mon packet est enregistrer côté client et il est sendtoserver donc envoyer côté serveur non?

LeBossMax2

@‘floriangabet’:

" Là tu envoi rien au serveur puis tu demande au serveur de faire le “rayTrace”. "

Je comprends pas.

Mon packet est enregistrer côté client et il est sendtoserver donc envoyer côté serveur non?

Je recommence :
Quand tu as enregistré ton packet :

network.registerMessage(PacketBalai.Handler.class, PacketBalai.class, 2, **%(#ff3333)[Side.CLIENT]**);

Là, tu a enregistrer le packet en disant qui peut être reçu Coté Client alors que tu veux qu’il soit reçu par le serveur il faut donc mettre “Side.SERVER”.

Ensuite :
Dans le MessageHandler de ton packet :

@SideOnly([size=medium**Side.CLIENT**]) //Réception du message coté client
@Overrid
public IMessage onMessage(PacketBalai message, MessageContext ctx) 
{
    System.out.println("")
    EntityPlayer playerIn = Minecraft.getMinecraft().thePlayer;

    …

}

Là, tu met la méthode en SideOnly Client donc seul le client peut recevoir le message. Là encore; Il faut mettre “Side.SERVER”.

De plus, dans ton item :

public ItemStack onItemUseFinish(ItemStack stack, World worldIn, EntityPlayer player)
{
    if(!worldIn.isRemote) {                                        //Si on est coté serveur
        if(stack != null && stack.getItem() == CSCItems.balai) {
            EntityPlayerMP p = (EntityPlayerMP)playerIn;
            Main.network.[size=medium**sendToServer**](new PacketBalai());       //Envoyer le packet au serveur
        }

    }
    return stack;
}

Ici, tu dis que si on est coté serveur, on envoie le packet vers le serveur. Il faut que tu mette if(worldIn.isRemote) ( = si on est coté client)

Et enfin on ta dit que tu devais utiliser les packets. C’est parce que le serveur ne peut pas faire “rayTrace” il faut donc que dans ton onItemUseFinish, si on est coté client, tu fait le rayTrace, tu get la position du block puis tu envoie la position au serveur. Le serveur, à la réception du message vas regarder le block à la position reçue et va faire tout le reste.

EDIT :

Le packet et le “rayTrace” on pas laire utiles finalement : tu à une variable “pos2” qui ne te ser pour l’instant à rien mais si tu l’enregistre dans les NBT Data de ton item, tu peut t’en servir dans “onItemUseFinish” pour directement avoir la position sans passer par packet+rayTrace.

Gabs

La variable pos2 tu la vois ouuu?

LeBossMax2

Dans la class de ton item :
Tu as la variable pos2 qui est mise à jour dans “onItemUse”.
Au lieu de la mettre comme une variable simple de la class de ton item, tu peut l’enregistrer dans la NBT tag de ton item et l’utiliser dans “onItemUseFinish” directement coté serveur.

EDIT :
Non, finalement, oublie ce que je viens de dire, la fonction “onItemUse” n’est appelée qu’une seule fois quand on reste appuyé sur click droit.

Cette ligne n’a rien à faire là :
EntityPlayerMP p = (EntityPlayerMP)playerIn;

Et tu n’as toujours pas comprit.

Tu dois faire le player.rayTrace(4, 0) avant d’envoyer le paquet et tu dois envoyer dans le paquet le résultat du raytrace.
Faire le rayTrace à l’arrivé du paquet ne sert à rien car ça fonctionne que en client.
