1.7.2 Créer un simple item

  • loustak

    Bonjour,
    j'ai créer la base de mon mod avec le tutoriel, ensuite j'ai voulu créer un item cependant je trouve le tuto beaucoup moins clair que le premier, donc mon code ressemble à ça :

    package com.gmail.loustak347.common;

import net.minecraft.item.Item;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.Mod.Instance;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;
import cpw.mods.fml.common.registry.GameRegistry;

@Mod(modid = "potionplus", name = "Potion+", version = "0.1")
public class PotionPlus {

@Instance("potionplus")
public static PotionPlus instance;
public static final String MODID = "potionplus";
public static Item testItem;
public class TestItem extends Item {
}

@EventHandler
public void preInit(FMLPreInitializationEvent event)
{
GameRegistry.registerItem(testItem, "item_test");
testItem = new TestItem().setUnlocalizedName("test").setTextureName(PotionPlus.MODID + ":testItem");
}

}

    Sauf que au lancement j'obtiens une erreur :

    Merci de votre aide.

    Ps: Pour plus de clarté se serait bien quand dans le tuto "créer un item basique" ce soit marqué l'endroit ou on doit taper le code 😉

    Si je ne me trompe pas, tu dois créer une class NomDeTonItem, et enlève public class Itemtest extends Item, c'est dans la class de ton Item que tu mets extends Item

    C'est pour cela, que pour chaque tutoriel 1.7.2, il y a une vidéo associée.

    Inverse le gameRegistry et la déclaration de ton item et fais ce qu'a dit zery59: mets ton items dans une class à part avec

    extends Item

    L'enregistrement doit se faire après l'initialisation de l'item.
