      Bonjour,
      J’ai suivi un tutoriel sur youtube expliquent comment créer un système de mana.
      Le problème est que la vidéos date de mai 2013 donc de la 1.5 voir de la 1.4, du coup même si aucune erreur n’est affiché sur éclipse le jeu ne traite pas l’information.

      J’ai essayé de modifié le code en le recoupant avec des infos plus récentes mais la le jeux crash complètement.

      Class Du joueur:

      package noob.common;

import net.minecraft.entity.Entity;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;
import net.minecraftforge.common.IExtendedEntityProperties;

public class CustomPlayer extends Entity implements IExtendedEntityProperties
{

private int mana;

public CustomPlayer(World par1World)
{
super(par1World);
}

@Override
public void saveNBTData(NBTTagCompound compound)
{
compound.setInteger("Mana level", this.mana);
}

@Override
public void loadNBTData(NBTTagCompound compound)
{
this.mana = compound.getInteger("Mana level");
}

@Override
public void init(Entity entity, World world)
{
this.mana = 0;
}

@Override
protected void entityInit() {
// TODO Auto-generated method stub

}

@Override
protected void readEntityFromNBT(NBTTagCompound nbttagcompound) {
// TODO Auto-generated method stub

}

@Override
protected void writeEntityToNBT(NBTTagCompound nbttagcompound) {
// TODO Auto-generated method stub

}

public int getMana()
{
return this.mana;
}

public void setMana(int lvl)
{
this.mana = lvl;
}

}

      Class de l’event:

      package noob.common;

import net.minecraft.entity.Entity;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraftforge.common.IExtendedEntityProperties;
import net.minecraftforge.event.ForgeSubscribe;
import net.minecraftforge.event.entity.EntityEvent.EntityConstructing;
import net.minecraftforge.event.entity.living.LivingDeathEvent;

public class AddCustomPlayerProperties
{

@ForgeSubscribe
public void init(EntityConstructing event)
{
if (event.entity instanceof EntityPlayer)
{
event.entity.registerExtendedProperties("Custom Player", new CustomPlayer(event.entity.worldObj));
}
}

@ForgeSubscribe
public void death(LivingDeathEvent event)
{
Entity source = event.source.getSourceOfDamage();
if (source != null)
{
if (event.entity instanceof EntityPlayer)
{
IExtendedEntityProperties prop = event.entity.getExtendedProperties("Custom Player");
int mana = ((CustomPlayer)prop).getMana()+1;
System.out.println("Mana de "+source.getEntityName()+"= "+mana);
((CustomPlayer)prop).setMana(mana);
}
}
}

}

      Sachant que j’ai bien mis cette ligne là: ```java
      MinecraftForge.EVENT_BUS.register(new AddCustomPlayerProperties());

      
Merci d'avance.

            C’est encore fonctionnel en 1.6, je pense que c’est un problème avec le tag nbt, enlève l’espace.
            Même chose pour le registerExtendedProperties évite les espaces dans les string.

                  Il n’y a pas de crash justement c’est ça que je trouve bizarre.
                  Rien de particulier ne s’affiche dans la console.

                        Je travaille sur les propriété d’entité actuellement.

                        
IExtendedEntityProperties prop = event.entity.getExtendedProperties("Custom Player");

                        Essaie

                        
CustomPlayer prop = new CustomPlayer(source.getEntityWorld());

                          Il me met une erreur à getEntityWorld()

                          désolé j’ai rien dit. En faisant cast sur le getEntityWorld() tout marche correctement ou presque cela affiche bien: “Mana de Player961= 1” mais il le ré-affiche a chaque fois et ne mais pas a jour la valeur de mana.

                            Non gugu, avec ça tu créer a chaque fois une nouvelle instance, le premier code était bon.
                            Tu as quoi à la ligne 29 de AddCustomPlayerProperties.java ?

                              Voila ce que j’ai à la ligne 29 :

                              int mana = ((CustomPlayer)prop).getMana()+1;

                                Si tu a suivi le tutoriel sur MinecraftForums.net, je l’ai suivi aussi, et il marche a la perfection.

                                    Renvoie tout tes codes, il y a un npe sur la ligne que tu a envoyé, donc je pense que le custom player prop est null. Il me faut tout tes codes actuels pour savoir pourquoi.

                                        Je te conseille le tutoriel ici :

                                        http://www.minecraftforum.net/topic/1952901-eventhandler-and-iextendedentityproperties/#entry24051513

                                        Car celui que tu utilise est fait de manière bizarre, il utilise l’interface pour appeler ton Custom Player.

                                            Juste pour information, le NPE d’avant été causé car tu n’avais pas le bon nom :

                                            IExtendedEntityProperties prop = event.entity.getExtendedProperties("Custom Player");

                                            La où tu l’as utilisé et :

                                            event.entity.registerExtendedProperties("Player", new CustomPlayer(event.entity.worldObj));

                                            La où tu l’as enregistré, si les noms sont pas les mêmes, normal que ça fonctionne pas x).
