Recuper la variable lorsque le joueur spawn pour la tout première fois.

[robin4002]

Je ne sais pas nom plus J’ai jamais vu ce type d’erreur, je ne vois pas d’où ça peut venir. Au pire as-tu vraiment besoin des paquets ?
Si tu fais juste l’action en serveur, le paquet ne sert à rien. Et sinon tu peux toujours passer par les DataWatcher

[Portuar]

Ouai j’en ai vraiment besoin c’est sa le problème.

[robin4002]

Dans ce cas passe au DataWatcher.

[Portuar]

et comment je connais pas non plus. Après j’ai trouvé ceci https://github.com/coolAlias/Forge_Tutorials/blob/master/IExtendedEntityPropertiesTutorial.java mais c’est en 1.6.4 et des choses sont inexistantes en 1.7

[robin4002]

EntityPlayer.getDataWatcher() fonctionne très bien en 1.7, on l’utilise dans nanotech hunger game

[Portuar]

Il y a un tutoriel ? et esque c’est assez simple, c’est à dire qu’on peut créer des fonction comme AddXp() etc?

[robin4002]

Simple a utiliser, et non il n’y a pas de tuto. Tiens un exemple :

package fr.mcnanotech.nhg.common;

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

public class CustomPlayerProperties implements IExtendedEntityProperties
{
private EntityPlayer player;
private int kitId;
public static final int KIT_WATCHER = 30;

public static final String NAME = "ngh_prop";

public CustomPlayerProperties(EntityPlayer player)
{
this.player = player;
this.player.getDataWatcher().addObject(KIT_WATCHER, this.kitId);
}

@Override
public void saveNBTData(NBTTagCompound compound)
{
compound.setInteger("PlayerKit", this.player.getDataWatcher().getWatchableObjectInt(KIT_WATCHER));
}

@Override
public void loadNBTData(NBTTagCompound compound)
{
this.player.getDataWatcher().updateObject(KIT_WATCHER, compound.getInteger("PlayerKit"));
}

@Override
public void init(Entity entity, World world)
{

}

public static CustomPlayerProperties get(EntityPlayer player)
{
return (CustomPlayerProperties)player.getExtendedProperties(NAME);
}

public int getKitIndex()
{
return this.player.getDataWatcher().getWatchableObjectInt(KIT_WATCHER);
}

public void setKit(int kitId)
{
this.player.getDataWatcher().updateObject(KIT_WATCHER, kitId);
}
}

[Portuar]

et quand le perso meurt il ne restart pas ?

---

Bon j’ai testé et donc j’ai voulut l’utilisé dans un item en faisant props.KIT_WATCHER++; juste pour teste mais il me dise d’enlever final dans : public static final int KIT_WATCHER = 30; mais si je le fait quand je me suicide le jeu crash

[robin4002]

Pour monter de un, setMachin(getMachin + 1)
Les setter et getter son la pour ça.
KIT_WATCHER n’est pas à modifier, c’est l’id du WATCHER, il faut modifier la valeur du watcher.

[Portuar]

ok j’ai testé mais quand je meurt sa reset…

[robin4002]

Alors la je ne sais pas
Faudrait demander sur le forum anglais de forge.

[Portuar]

JAI ENFIN REUSSI YESSSSSS !

[Superloup10]

Tu peux donner la solution pour les autres membres qui auraient le même problème?
