Créer un bloc type four (machine)

SCAREX

Rajoute l’annotation @Override au-dessus de la méthode updateEntity et rajoute un system.out.println dans la classe des recipes ou dans la classe updateEntity pour savoir le contenu des variables et des items de ton inventaire.

Flow

J’ajoute le system.out.println comme ca et au début de tout ou avec system.out.println(“QCCH”); ?

SCAREX

Faire un System.out.println(“quelque chose”) te permet de voir quelles parties du codes sont exécutées et à quel moment. Donc mets en là où tu penses que le code ne va peut être pas.

Flow

J’ai regarder et rien ne s’affiche , ca ne veut pas donner le résultats , je ne comprend pas

SCAREX

C’est le but du debug, maintenant remonte chaque fonction pour voir où çà bloque, c’est là que faire clique droit sur ta fonction puis “Open call hierarchy” est utile.

Flow

Jvais tout revérifier encore une fois avec le tuto pour voir si j’ai bien tout mis , ca sera plus simple je pense que de chercher dans toutes les classes.

Euhm, mon gui ne s’ouvre pas…?

@‘DiabolicaTrix’:

Euhm, mon gui ne s’ouvre pas…?

Sans ton code ça va être difficile de trouver où est l’erreur.

@xav, il faut pas répondre aux messages avec fond rouge/violet, ce sont des messages supprimés par le membre qui l’a posté (tu les voit car en tant que modo tu peux les restaurer).

Ah ouais, désolé xP.

Cette fonction n’a rien à faire dans Recipes.java, elle doit être dans le bloc.

DiabolicaTrix

Hahaha comment je me suis fail… je croyais que j’étais dans bloc xP Merci!

J’ai compris pourquoi, Eclipse coupe le nom donc ça affiche: BlockAlloyF…

Le gui ne s’affiche pas mais la main du perso va vers le bloc contrairement à avant

robin4002

Ton gui handle est bien enregistré ?

DiabolicaTrix

Oui, car mon Gui de Coffre fonctionne

NetworkRegistry.INSTANCE.registerGuiHandler(instance, new GuiHandler());

robin4002

Ah en fait j’avais pas fait attention. Tu as seulement ton coffre dans le gui handler. Ta machine n’y est pas.

DiabolicaTrix

Maintenant, j’ai un NPE ici:

 public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int side, float hitX, float hitY, float hitZ)
    {
        if (world.isRemote)
        {
            return true;
        }
        else
        {
                player.openGui(Base.instance, 0, world, x, y, z); <–- ICI

            return true;
        }
    }

Honnêtement je ne comprend pas trop le openGui.

robin4002

Étrange. La seule chose qui peut être null c’est l’instance. Tu as quoi dans la classe Base ?

L’instance est pourtant ok …
Tu es sur que tu as bien un NPE sur cette ligne et non une autre ? Envoies le rapport de crash.

Le NPE se trouve ici :
at net.minecraft.inventory.Slot.getStack(Slot.java:88) ~[Slot.class:?]

public ItemStack getStack()
{
return this.inventory.getStackInSlot(this.slotIndex); // ligne 88
}

Donc inventory est null alors qu’il ne devrait pas.
Et en effet dans ton container :

[…]
public class ContainerAlloyFurnace extends Container {

private TileEntityAlloyFurnace tileAlloyFurnace; // revient à faire private TileEntityAlloyFurnace tileAlloyFurnace = null;

public ContainerAlloyFurnace(TileEntityAlloyFurnace tile, InventoryPlayer inventory)
{

this.addSlotToContainer(new Slot(this.tileAlloyFurnace, 0, 49, 75));
this.addSlotToContainer(new Slot(this.tileAlloyFurnace, 1, 89, 75));
this.addSlotToContainer(new Slot(this.tileAlloyFurnace, 2, 129, 75));
this.addSlotToContainer(new SlotResult(this.tileAlloyFurnace, 3, 89, 135));
this.bindPlayerInventory(inventory);
}
[…]

Regarde bien, this.tileAlloyFurnace est toujours null.
Il te manque la ligne this.tileAlloyFurnace = tile au début du constructeur.
