Clique droit avec un item = Effet de potion

[loustak]

Alors ma question va surement te paraître bête mais comment faire une classe qui hérite de mon item ?
Mon item est déclarée dans la page du mod principale (je n’est pas créer de classe spécifique)
du coup j’ai ça actuellement comme code :

miningPotion = new ItemFood(0, 0.1f, false).setPotionEffect(3, 120, 2, 1.0f).setUnlocalizedName("miningPotion").setTextureName(PotionPlus.MODID+":miningPotion");
public ItemStack onItemRightClick(ItemStack stack, World world, EntityPlayer player)
{
player.addPotionEffect(1);
player.setCurrentItemOrArmor(0, null);
return super.onItemRightClick(stack, world, player);
}
GameRegistry.addShapelessRecipe(new ItemStack(miningPotion), new Object[]{new ItemStack(Items.potionitem, 1),new ItemStack(hotSlimeBall)});
GameRegistry.registerItem(miningPotion, "miningPotion", PotionPlus.MODID);
miningPotion.setCreativeTab(tabPotionPlus); //On ajoute l'item à la table créative

Encore merci

edit: eclipse me dit qu’il y a une erreur sur la ligne ‘public item stack on right click…’ : Multiplz marker at this line

Voir tuto comment créer un item:
http://www.minecraftforgefrance.fr/showthread.php?tid=588

et après tu ajoute la méthode:

public ItemStack onItemRightClick(ItemStack stack, World world, EntityPlayer player)
{
event.player.addPotionEffect(new PotionEffect(id, temps, level));
if (!player.capabilities.isCreativeMode)
{
–stack.stackSize;
}
return stack;
}

“id” “temps” et “level” sont à remplacer

pour les ids d’effets de potions:
Potion.nom.id
le “nom” est à remplacer par le nom de l’effet.

Alors en faite j’ai toutes mes classes dans c’elle de mon mod :

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

@Instance("modtutoriel")
public static final String MODID = "potionPlus";

@Instance(MODID)
public static PotionPlus instance;
//On créer la table en créatif
public static CreativeTabs tabPotionPlus = new CreativeTabs("potionPlus") {
@Override
@SideOnly(Side.CLIENT)
public Item getTabIconItem()
{
return Items.potionitem;
}
};

public static Item hotSlimeBall;
public static Item miningPotion;

@EventHandler
public void preInit(FMLPreInitializationEvent event)
{
hotSlimeBall = new Item().setTextureName(PotionPlus.MODID+":hotSlimeBall").setUnlocalizedName("hotSlimeBall");
GameRegistry.addSmelting(Items.slime_ball,new ItemStack(hotSlimeBall) , 0.0f);
GameRegistry.registerItem(hotSlimeBall, "HotSlimeBall", PotionPlus.MODID);
hotSlimeBall.setCreativeTab(tabPotionPlus); //On ajoute l'item à la table créative

miningPotion = new ItemFood(0, 0.1f, false).setPotionEffect(3, 120, 2, 1.0f).setUnlocalizedName("miningPotion").setTextureName(PotionPlus.MODID+":miningPotion");

GameRegistry.addShapelessRecipe(new ItemStack(miningPotion), new Object[]{new ItemStack(Items.potionitem, 1),new ItemStack(hotSlimeBall)});
GameRegistry.registerItem(miningPotion, "miningPotion", PotionPlus.MODID);
miningPotion.setCreativeTab(tabPotionPlus); //On ajoute l'item à la table créative
}
}

Ets-ce que c’est possible même comme ça ?

[zery59]

Tu dois créer une class NomDeTonItem, et remplace new ItemFood par new NomDeTonItem, puis créé une class avec le NomDeTonItem. Mais attend que quelqu’un vérifie ce que je dis, pour être sur de ne pas faire de bêtises

[kevin_68]

Exact zery59

[loustak]

Du coup j’ai ça :

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.potion.PotionEffect;
import net.minecraft.world.World;

public class miningPotion {
public ItemStack onItemRightClick(ItemStack stack, World world, EntityPlayer player)
{
event.player.addPotionEffect(new PotionEffect(3, 20, 2));
if (!player.capabilities.isCreativeMode)
{
–stack.stackSize;
}
return stack;
}
}

Mais il me souligne en rouge event et dit : ‘event cannot be resolved’

[robin4002]

Mets juste player, enlève event.

Je pense que ça viens de quelque part ici :

public void preInit(FMLPreInitializationEvent event)
{
hotSlimeBall = new Item().setTextureName(PotionPlus.MODID+":hotSlimeBall").setUnlocalizedName("hotSlimeBall");
GameRegistry.addSmelting(Items.slime_ball,new ItemStack(hotSlimeBall) , 0.0f);
GameRegistry.registerItem(hotSlimeBall, "HotSlimeBall", PotionPlus.MODID);
hotSlimeBall.setCreativeTab(tabPotionPlus); //On ajoute l'item à la table créative

new miningPotion();
GameRegistry.addShapelessRecipe(new ItemStack(miningPotion), new Object[]{new ItemStack(Items.potionitem, 1),new ItemStack(hotSlimeBall)});
GameRegistry.registerItem(miningPotion, "miningPotion", PotionPlus.MODID);
miningPotion.setCreativeTab(tabPotionPlus); //On ajoute l'item à la table créative
}

edit :
Mon ancienne ligne était :

miningPotion = new ItemFood(0, 0.1f, false).setPotionEffect(3, 120, 2, 1.0f).setUnlocalizedName("miningPotion").setTextureName(PotionPlus.MODID+":miningPotion");

[robin4002]

miningPotion = new miningPotion().setUnlocalizedName(“miningPotion”).setTextureName(PotionPlus.MODID+“:miningPotion”);
et pas new miningPotion(); …

[loustak]

C’est ce que j’avait fait au début mais il me souligne ‘.setUnlocalizedName’ et tous les autres arguments car : d’après eclipse elle ne sont pas définit pour le type ‘mininPotion’
Je rapelle ma page miningPotion.java :
:::
package com.gmail.loustak347.common;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.potion.PotionEffect;
import net.minecraft.world.World;

public class miningPotion {

public ItemStack onItemRightClick(ItemStack stack, World world, EntityPlayer player)
{
player.addPotionEffect(new PotionEffect(3, 20, 2));
if (!player.capabilities.isCreativeMode)
{
–stack.stackSize;
}
return stack;
}
}

[Überfap]

public class miningPotion extends Item {

[isador]

c’est la base ca a tu au moins lu le tuto pour créer un item?

[loustak]

Merci ça fonctionne normalement, et sinon oui j’avais vu le tuto pour créer un item.
