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.

Ah parfait, merci beaucoup, ça fonctionne!

J’avais une question , tu parle du nom de la machine mais même dans les photos le nom n’apparaît pas c’est normal ?

[DiabolicaTrix]

Il ne l’a pas print

[Sleindarfeau]

Bonsoir,

Quand je fais un shift+click pour envoyer ou retirer un stack de la machine, il me reste un item fantôme dans le slot, que ça soit dans mon inventaire ou dans la machine. L’ItemStack n’est pas redéfini à null. Je pense que ça doit venir des fonctions getStackInSlotOnClosing(int index) et setInventorySlotContent(int index, ItemStack stack). Le problème, c’est que ce sont exactement les mêmes que dans le tuto… Voilà le code :
