Blocks de portail

bin4r1s

Apparemment il semble que ça marche avec des blocs (de mon mod) possédant une classe dédiée (type BlockGrass).

L’erreur doit être dans cette classe (le système du drop est une expérience) :
BlockDragonsMod.java :


package fr.MrBlockTNT.Dragons.block;

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.item.Item;
import fr.MrBlockTNT.Dragons.core.Dragons;

public class BlockDragonsMod extends Block
{
Block drop;

public BlockDragonsMod(Material material)
{
super(material);
drop = null;
this.setCreativeTab(Dragons.DragonsTab);
}

public BlockDragonsMod(Block block, Material material)
{
super(material);
drop = block;
this.setCreativeTab(Dragons.DragonsTab);
}

public Item getItemDropped(int a, Random b, int c)
{
return Item.getItemFromBlock(this.drop);
}
}

Euh essaie de mettre en commentaire ta ligne


drop = null

pour voir si ça change quelque chose

Je vois pas de problème en rapport avec ton histoire de portail.
En revanche fait attention, celle classe peut déclencher un NPE …
Normalement tu mets TaClassePrincipale.nomDuBloc et voila.

bin4r1s

Je pense pas étant donné que mon block “structure” possède les 2 arguments (logiquement, drop sera quand même null), mais je teste quand même.

EDIT : C’est bien ce que je pensais ça ne marche pas.

A désolé je n’avais pas vu.
Le rapport avec le portail c’est que c’est la classe du bloc ‘structure/container’ du portail.

Je ne comprends plus rien : avec deux classes différentes possédant le même code un bloc sur les deux marche…

Diangle

Je ne comprend pas ton problème xD.

robin4002

Envoie tout tes codes en rapport avec le portail.

Classe principale (Dragons.java) :

fire_stone = (new BlockDragonsMod(this.fire_stone, Material.rock)).setHardness(20.0F).setResistance(2000.0F).setStepSound(Block.soundTypeStone).setBlockName("fire_stone").setBlockTextureName("dragons:fire_stone");

Dans le constructeur de la classe IDimBlockPortal, ajoutes :
System.out.println(portalMaterial.getUnlocalizedName());

ça t’affiche son nom dans la console ou le jeu crash avec un NPE ?

bin4r1s

Ah ! NPE !

Comment le solutionner ?

Bon voila, on a trouvé le problème, portalMaterial est null.
Donc ça veut dire qu’au moment ou tu initialises ton bloc IDimBlockPortal, Dragons.fire_stone est null.
La solution ? Il faut juste initialisé fire_stone avant IDimBlockPortal dans ta classe principale.
Et voila.

Ah merci :), je teste.

EDIT: ça marche à la perfection, sujet résolu.
