Créer un item container (type backpack / sac à dos)

[SCAREX]

Je crois que c’est spécifié à plusieurs endroits dans les commentaires : dans le container et dans le slot

[Un Ancien Utilisateur]

ses possible de faire pour que un item ne soit pas posée dans le back pack ?

[robin4002]

Oui, il suffit de modifier cette fonction :

@Override
public boolean isItemValidForSlot(int index, ItemStack stack) {
return !(stack.getItem() instanceof ItemBackPack);
}

↓↓

@Override
public boolean isItemValidForSlot(int index, ItemStack stack) {
return !(stack.getItem() instanceof ItemBackPack) && !(stack.getItem() == ClassePrincipale.item);
}

[ZomDev]

Salut !
J’ai crée plusieurs backpacks mais le problème c’est que quand je clique sur un item dans mon premier backpack ça marche, mais dans les autres l’item se drop
Une idée d’où cela pourrait venir ?

[SCAREX]

Bh j’ai fait sa : GameRegistry.addRecipe(new ItemStack(ModItems.ITEM_BACKPACK), new Object[]{“###”, “# #”, “###”, ‘#’, Items.leather});
Mais quand je met la Leather bh mon jeu crash…

File ta classe principale. Ta recette est sûrement enregistrée avant tes items, d’où une possible NPE.

Jdois faire ccomment ?

[Yanis_]

c’est dans le preinit non ? que tu doit register ton craft

[AymericRed]

Non les crafts peuvent être mis dans l’init sans problème.

Par contre tu peux m’expliquer pourquoi tu as “BlockMod”, “ItemMod” ET “ModItems”, “ModBlocks” ?
Et tous cas ton problème vient du fait que t’enregistre des items et blocks dans le postInit, ce qu’il ne faut JAMAIS faire.

@‘Yanis (MrLeBest)’:

Salut,
Il y a soit un soucis avec la variable instance de ton mod, soit tu n’as pas enregistré de gui handler.

[Zoulette]

Bonjour au niveau du guiHandler http://prntscr.com/g1ng7k
et au niveau de l’instance je viens de remarquer cela http://prntscr.com/g1nk53
[EDIT 1]: si tu peux m’aider cela serait juste géniale parce que je galère depuis hier soir
