Clique droit avec un item = Effet de potion

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.

Ok j’ai essayer plus d’erreur pour eclipse mais un crash au lancement de minecraft :

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

loustak

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