Problème avec les events.

tybau

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.

Mauvaise section

Überfap

Gugu42 à raison, de plus j’ai suivi le même tutoriel, et il est parfaitement fonctionnel en 1.6

robin4002

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.

tybau

J’ai enlevé les espaces mais sa ne change rien.

robin4002

Envoie le crash report.

tybau

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

Ton event death est foireux.

@ForgeSubscribe
public void death(LivingDeathEvent event)
{
Entity source = event.source.getEntity();
if (source != null && source 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);
}
}

Gugu

Je travaille sur les propriété d’entité actuellement.


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

Essaie


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

tybau

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.

robin4002

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 ?

tybau

Voila ce que j’ai à la ligne 29 :

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

Gugu

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

tybau

Je n’est pas suivit celui là. Je vais regarder ce tutoriel la.

robin4002

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.

tybau

Voila le code de AddCustomPlayerProperties:

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

@ForgeSubscribe
public void death(LivingDeathEvent event)
{
Entity source = event.source.getEntity();
if (source != null && source 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);
}
}

}

Gugu

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.

tybau

Ok merci je vais regarder.

Merci beaucoup sa marche!
Je pense que je vais pouvoir avancé maintenant.

robin4002

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).

Résolu Problème avec les events.
