Au fait j’ai pas trouvé pour le crash.

[robin4002]

Tu as enregistré ton ExtendedEntityPropAlcool ?

[Gabs]

J’ai rien régister c’est ou que je dois le register ?

EDIT: J’ai mis ça dans la class principale :

     FMLCommonHandler.instance().bus().register(new ExtendedEntityPropAlcool(null));

    MinecraftForge.EVENT_BUS.register(new ExtendedEntityPropAlcool(null));

[BrokenSwing]

Euh …. Fait plus ça s’il te plaît

Je crois qu’il voulait parler de l’event EntityEvent.EntityConstructing

**EDIT : ** ou pas xD

[robin4002]

…
C’est pas du tout comme ça qu’il faut l’enregistrer. Il faut passer par l’event EntityEvent.EntityConstructing.

[Gabs]

Peut-etre mieux non?

   @SubscribeEvent
public void onEntityConstructing(EntityConstructing event) 
{
if (event.entity instanceof EntityPlayer && ExtendedEntityPropAlcool.get((EntityPlayer) event.entity) == null)
ExtendedEntityPropAlcool.register((EntityPlayer) event.entity);
}

[robin4002]

Oui. Tu as bien mit cette ligne dans une classe que tu as enregistré avec MinecraftForge.EVENT_BUS.register(new NomDeLaClasse()); ?

[Gabs]

Alors oui mais je les mis dans ExtendedEntityPropAlcool c’est pas grave ?

car j’ai une érreur sur le: [font=Ubuntu, sans-serif```java
MinecraftForge.EVENT_BUS.register(new ExtendedEntityPropAlcool());

[font=Ubuntu, sans-serifil me demande de vire le EntityPlayer de cette ligne (cette ligne est dans le ExtendedEntityPropAlcool):]
[font=Ubuntu, sans-serif```java
  public ExtendedEntityPropAlcool*(***EntityPlayer player***)* {]
[font=Ubuntu, sans-serif}
```]

[robin4002]

Fait une autre classe nommé EntityEvent, ça sera mieux.

[Gabs]

Ouaip merci j’essaye ça je vous dis.

[Gabs]

Crash réglé mais quand un joueur boit et que j’interagi avec le clic droit sa m’indique 0 et quand on inverse c’est pareil 0 aussi.

[robin4002]

Tu as bien changé le code dans les autres items ?

[Gabs]

J’ai j’ai changer la class At qui permet de prendre le niveau d’alcool par contre j’ai pas touché a la class LIIT qui est la class pour les boissons d’alcool est donc normalement ajouté le niveau d’alcool .

package com.AltisMine.mod;

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

public class LIIT extends ItemFood {

 AT alcohol = new AT();

public LIIT (int itemID, int i, boolean b)
 {
   super(itemID, i, b);

}

 public EnumAction getItemUseAction(ItemStack itemstack)
 {
   return EnumAction.drink;
 }
   public ItemStack onItemRightClick(ItemStack stack, World world, EntityPlayer player)
   {
       if (player.canEat(true))
       {
           player.setItemInUse(stack, this.getMaxItemUseDuration(stack));
       }
       return stack;
   }

   public int getMaxItemUseDuration(ItemStack stack)
   {
       return 32;
   }

   public ItemStack onEaten(ItemStack stack, World world, EntityPlayer player)
   {
       –stack.stackSize;
       ExtendedEntityPropAlcool.alcoolvl = Math.abs(ExtendedEntityPropAlcool.alcoolvl +1);
       player.getFoodStats().addStats(1, 2); // nombre de demi-gigots + saturation
       world.playSoundAtEntity(player, "random.burp", 0.5F, world.rand.nextFloat() * 0.1F + 0.9F);
       player.addPotionEffect(new PotionEffect(Potion.confusion.id, 315,0));
       player.addPotionEffect(new PotionEffect(Potion.digSlowdown.id, 315,0));
       player.addPotionEffect(new PotionEffect(Potion.hunger.id, 315,0));
       player.addPotionEffect(new PotionEffect(Potion.weakness.id, 315,0));
return stack;
   }
   @Override
 public boolean hasEffect(ItemStack par1ItemStack){
  return true;
 }

}

[BrokenSwing]

ExtendedEntityPropAlcool prop = ExtendedEntityPropAlcool.get(player);
prop.setAlcool(prop.getAlcool() + 1);

[robin4002]

Et la variable alcoolvl de la classe ExtendedEntityPropAlcool ne doit pas être static. Sinon ton ExtendedEntityPropAlcool n’a plus aucun intérêt (les instances ça fait partie de la base Java vivement que le tutoriel soit publié).

[BrokenSwing]

**Hors-Sujet : ** Oui mais est-ce-que ceux qui ne prenez même pas la peine d’apprendre le Java sur OpenClassroom prendront la peine de regarder des tutoriels de Java sur MFF ? C’est la question que je me pose …
Vu que c’est du hors-sujet tu peux supprimer le message, je soulevais juste la question

[robin4002]

Une fois que le tutoriel sera disponible je ne vais plus m’embêter. Si quelqu’un demande de l’aide dans support pour les moddeurs et que je remarque que le minimum nécessaire pour coder en Java n’est pas acquis ça sera lock + lien vers le tutoriel.
À la base la description de la section c’est ça :

Il s’agit de la section de support pour ceux qui créent des mods avec Forge. L’aide au modding va ici, cependant, gardez à l’esprit que ce n’est pas une école de programmation Java. Vous êtes censé avoir au moins certaines base de Java avant de poster ici.

[Gabs]

J’ai fais comme vous avez dis mais j’ai un problème encore :

[Gabs]

Merci problème réglé par conte c’est exactement pareil 0 même lorsque on boit.

Edit:
Je suis sur que le problème vient d’ici:

public int getAlcool() {
this.alcool = 0;
if (alcool != 0)
alcool = Math.abs(alcool / 2);
  else if (alcool == 0) {
  alcool = Math.abs(alcool);
  }
           return this.alcool;
   }

}
