    Bonjour, je me présente ,Eryah, moddeur débutant et maladroit.
    Je réalise le mod UsefulThings ( Progression ici : http://forum.minecraft-france.fr/threads/usefulthings-project.28533/ ). J’ai codée mon Item “Moteur”, et il peut être crafter. Mais lorsque je le craft, que je pose mon curseur sur l’item dans la table de craft, mon jeu crash.

    Code du moteur

    

    package eryah.usefulthings.init;

import net.minecraft.client.Minecraft;
import net.minecraft.client.resources.model.ModelResourceLocation;
import net.minecraft.item.Item;
import net.minecraftforge.fml.common.registry.GameRegistry;
import eryah.usefulthings.Reference;
import eryah.usefulthings.UsefulthingsMod;

public class Engine {

public static Item engine;

public static void init(){
engine = new Item().setUnlocalizedName("engine").setCreativeTab(UsefulthingsMod.UTTab);
}

public static void register()
{
GameRegistry.registerItem(engine, engine.getUnlocalizedName().substring(5));
}

public static void registerRenders()
{
registerRender(engine);
}

public static void registerRender(Item item)
{
Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, new ModelResourceLocation(Reference.MOD_ID + ":" + item.getUnlocalizedName().substring(5), "inventory"));
}

}

    Partie du code dans le .java de base qui gère le craft

    @EventHandler
public void init(FMLInitializationEvent event)
{
proxy.registerRenders();
GameRegistry.addRecipe(new ItemStack(engine), new Object[]{" R ", "PRP","RRR", 'R',Items.redstone, 'P',Blocks.piston});
}

    Salut,
    Ton item semble être null au moment où tu enregistre la recette. Tu dois d’abord initialiser l’item et l’enregistrer puis enregistrer la recette.

    Je ne comprend pas trop ce que vous voulea dire par l’initianliser, et par il est ‘null’

    Les deux lignes :

    ​   public static final Item UTresin = new Item();
  public static final Item engine = new Item();

    ne devrait pas exister.
    Et tu aurai du mettre :

     GameRegistry.addRecipe(new ItemStack(Engine.engine), new Object[]{" R ", "PRP","RRR", 'R',Items.redstone, 'P',Blocks.piston});

    avec l’organisation que tu utilises actuellement. D’ailleurs je ne vois pas l’intérêt d’organiser les classes de la façon dont tu le fais. Il serait mieux de mettre les déclarations d’items dans la classe principale, ou alors dans une même classe pour tous les items, mais une classe par item je ne vois vraiment pas l’intérêt. Ça fragmente plus qu’autre chose le code.

    Et un peu de programmation en général :
    l’initialisation, c’est quand tu affectes une première valeur à une variable.
    Par exemple, cette variable :

    public static String[] array;

    est null, car elle n’a pas été initialisé.
    Par contre celle-ci :

    public static String[] array = new String[]{"une valeur", "une deuxième", "oui, plusieurs valeurs comme c'est un tableau ;)"};

    est initialisé.
    Lorsqu’on fait appel à une méthode d’un objet non initialisé (donc null) une erreur du type NullPointerException est levé.

    Bah je suis incapable de faire un code par moi même(même si je commence a tenter des choses) , je cherche donc des tutos sur youtube et sur internet. C’est le code de MRCrayfish, sauf que le tuto est en 1.7

    Cette ligne

    GameRegistry.addRecipe(new ItemStack(engine), new Object[]{" R ", "PRP","RRR", 'R',Items.redstone, 'P',Blocks.piston});

    Pour moi le

    new ItemStack(engine)

    je suis obligé de l’écrire comme ca :

    new ItemStack(engine, QUANTITE)

    Donc que tu désire mettre (1 à 64)  sinon mon jeu ne ce lance même pas, me demande pas pourquoi x).

    Ensuite ça :

    {" R ", "PRP","RRR"

    C’est exactement pareil je doit l’écrire d’un certaine facon comme :

    {"NRN", "PRP","RRR", 'R',Items.redstone, 'P',Blocks.piston});

    N pour moi signifie Null.

    Edit: J’ai écrit le post au même moment que Robin désolé :3
