SOLVED Exécuter des fonctions au déplacement d'un ItemStack dans un Container
-
Bonjour à tous.
J’ai créé une petite fonction qui doit être exécutée à chaque fois qu’on interagit avec les objets dans un container lui aussi fait maison.
J’ai donc une TE, un Container, une Gui et un BlockContainer.Je n’ai pourtant pas trouvé une seule fonction appelée dans cette situation, même sur internet.
Pouvez-vous m’aider ?
Merci d’avance.

public ItemStack transferStackInSlot(EntityPlayer player, int slotId)
Dans le container, cette fonction est déclenché dès qu’un item stack est placé dans un slot. -
Merci.
En revanche, cela ne fonctionne pas, mais ça doit définitivement être ma faute.
J’ai ceci dans mon Container :
private TileEntityEUsInjector tileEntity; public ItemStack transferStackInSlot(EntityPlayer player, int slotId) { ItemStack itemstack = null; Slot slot = (Slot)this.inventorySlots.get(slotId); tileEntity.countBattery(); if(slot != null && slot.getHasStack()) { ItemStack itemstack1 = slot.getStack(); itemstack = itemstack1.copy(); if(slotId < 9) { if(!this.mergeItemStack(itemstack1, 9, this.inventorySlots.size(), true)) { return null; } } else if(!this.mergeItemStack(itemstack1, 0, 9, false)) { return null; } if(itemstack1.stackSize == 0) { slot.putStack((ItemStack)null); } else { slot.onSlotChanged(); } } return itemstack; }On y aperçoit l’appel d’une fonction countBattery présente dans la TE du Container. Voici cette fonction :
public void countBattery() { int upgrades = 0; // TODO Debug if (this.inventory[0].getUnlocalizedName() == "quantumUpgrade") upgrades++; if (this.inventory[1].getUnlocalizedName() == "quantumUpgrade") upgrades++; if (this.inventory[2].getUnlocalizedName() == "quantumUpgrade") upgrades++; if (this.inventory[3].getUnlocalizedName() == "quantumUpgrade") upgrades++; System.out.println("Upgrades: " + upgrades); if (upgrades == 0) this.setMaxVoltage(32); else if (upgrades == 1) this.setMaxVoltage(128); else if (upgrades == 2) this.setMaxVoltage(512); else if (upgrades == 3) this.setMaxVoltage(2048); else if (upgrades == 4) this.setMaxVoltage(-1); }(this.inventory étant l’inventaire relatif à la TE)
Ainsi, cette fonction est sensée, une fois exécutée, effectuer setMaxVoltage en conséquence. Elle print aussi dans les logs une manifestation.
Hors, lorsque je déplace un objet dans mon container, aucune réaction.
Pouvez-vous m’aider ?Encore une fois merci d’avance.

Alors en effet la fonction n’est que déclenché quand on utilise shift + clic.
J’ai rapidement regardé, dans le tile entity, la fonction setInventorySlotContents est déclenché quand on met un item, mais aussi quand on ouvre le container. decrStackSize elle est déclenché quand on prend un item du container.Donc au final j’ai pas trouvé ce que tu cherches
-
A la limite c’est pas très grave si elle est exécutée un peu plus. En fait, j’aurai bien voulu qu’elle soit exécuté en permanence, mais ça pomperait de la ressource serveur. Mais là vu que tu me dis ces fonctions, je vais tester.
Merci.
EDIT : Alors j’ai placé la fonction comme ceci sans setInventorySlotContents :
@Override public void setInventorySlotContents(int slotId, ItemStack stack) { this.inventory[slotId] = stack; if (stack != null && stack.stackSize > this.getInventoryStackLimit()) { stack.stackSize = this.getInventoryStackLimit(); } countBattery(); this.markDirty(); }Mais à l’ouverture du GUI, j’ai le temps de l’aperçevoir et puis vlan :

Je pense que c’est ma fonction qui déconne. Je vais faire des tests.
EDIT 3 : Ok résolu ! En fait c’était ma faute, je vérifiais pas si le ItemStack était pas nul (ce qui est le cas quand le slot est vide). Merci pour votre aide !
