Résolu Aide pour item avec meta data

[Eryah]

Bonjour à tous, je me présente, Eryah.
Je voudrais faire en sorte que ma balle de fusil et la douille soit le même item, donc avec des metadatas.
J’ai pris un code sur un tuto sur internet (http://bedrockminer.jimdo.com/modding-tutorials/basic-modding-1-8/blockstates-and-metadata/)
Et la, je bloque
Je pense que j’ai fais du bousin, en même temps, déjà que j’ai moi-même une manière étrange de fonctionner, et que lui de même ( Français pas être ), c’est assez dur de reprendre son code
Je crash au lancement du jeu

}

Sur le getUnlocalizedName, j’ai rien compris, je pense que sa ce voit bien

[robin4002]

Il faut mettre la fonction
ModelBakery.addVariantName(Bullet.bullet, “ut:bullet”, “ut:bullet_casing”);
après avoir initialisé l’item en question, sinon c’est normal que ça fasse un NPE.

[Eryah]

Je coince pour la texture, faut mettre les 2 textures dans le même json ?

[robin4002]

Non. Il faut 2 json, un nommé bullet et l’autre bullet_casing (ce que tu as mit dans la méthode addVariantName).
Ensuite pour enregistrer le json au lieu d’utiliser la méthode normal avec l’itemMesher il faut faire :

ModelLoader.setCustomMeshDefinition(tonItem, new ItemMeshDefinition()
{
@Override
public ModelResourceLocation getModelLocation(ItemStack stack)
{
if(stack.getItemDamage() == 1) // metadata 1
{
return new ModelResourceLocation("ut:bullet_casing", "inventory");
}
return new ModelResourceLocation("ut:bullet", "inventory"); // autres metadatas, 0 comprit.
}
});

(à mettre dans preInit, après l’initialisation de l’item)

[Eryah]

J’ai mis dans Postinit, comme c’est, c’est sûr
Mais j’ai toujours pas de texture sur Bullet_casing.
Sa gène si ma texture à un nom différent ? Je pense que non, vu que le model redirige vers la texture

[robin4002]

(à mettre dans preInit, après l’initialisation de l’item)
J’ai dit preInit, c’est pas pour rien. Si tu ne mets pas dans preInit ça ne peut pas fonctionner.

[Eryah]

AH c’est bon.
Bah Erreur de ma part désolé.
