Hey guys. I have a problem which is exactly what the title says. I have made a Container and opening it up works fine. I have not tested putting something in and taking it out again because well I have bind player's Inventory and a custom inventory and try to let items be switched between them. I guess I have to override some method in the Container. Here are my 2 files:

 

MHItemChestContainer:

If you need anything else, just ask for it

Thanks for your time

Your transferStackInSlot function is returning null. If this is happening on shift-click then you should consider putting some code in there.

 

Mine looks like this.

 

 

 

  /**
     * Called when a player shift-clicks on a slot. You must override this or you will crash when someone does that.
     */
    public ItemStack transferStackInSlot(EntityPlayer par1EntityPlayer, int par2)
    {
        ItemStack var3 = null;
        Slot var4 = (Slot)this.inventorySlots.get(par2);

        if (var4 != null && var4.getHasStack())
        {
            ItemStack var5 = var4.getStack();
            var3 = var5.copy();

            if (par2 == 2)
            {
                if (!this.mergeItemStack(var5, 3, 39, true))
                {
                    return null;
                }

                var4.onSlotChange(var5, var3);
            }
            else if (par2 != 1 && par2 != 0)
            {
                if (MillRecipes.smelting().getSmeltingResult(var5) != null)
                {
                    if (!this.mergeItemStack(var5, 0, 1, false))
                    {
                        return null;
                    }
                }
                else if (TileEntityMill.isItemFuel(var5))
                {
                    if (!this.mergeItemStack(var5, 1, 2, false))
                    {
                        return null;
                    }
                }
                else if (par2 >= 3 && par2 < 30)
                {
                    if (!this.mergeItemStack(var5, 30, 39, false))
                    {
                        return null;
                    }
                }
                else if (par2 >= 30 && par2 < 39 && !this.mergeItemStack(var5, 3, 30, false))
                {
                    return null;
                }
            }
            else if (!this.mergeItemStack(var5, 3, 39, false))
            {
                return null;
            }

            if (var5.stackSize == 0)
            {
                var4.putStack((ItemStack)null);
            }
            else
            {
                var4.onSlotChanged();
            }

            if (var5.stackSize == var3.stackSize)
            {
                return null;
            }

            var4.onPickupFromSlot(par1EntityPlayer, var5);
        }

        return var3;
    }

 

 

It's happening all the time no matter if I shift-click or click normally. Though I will try to put parts of your code in. Thanks for sharing If you have something against that please answer.

 

Sincerely Me

Nothing has changed with the new, of c I changed the code to fulfill my expectations, code. Well I hope you (community) can keep the great support coming

Not sure if this is helpful or not, but it sounds a lot like the MC bug that can happen in full screen mode. That is usually fixed by going to windowed mode, and/or hitting the ALT key a couple times while in an inventory gui.

 

I'd check that just to be sure you rule out a runtime bug and not the code.

Nope I tried it out and nothing I really tried to stick to this tutorial: http://www.minecraftforge.net/wiki/Containers_and_GUIs but well it seems not to work...

Actually it was a problem with the GUI. The GUIContainer class features a ySize-variable which defines wheter you have clicked "out of the GUI". If yes then the ItemStack you have in-hand is thrown away. As my GUI was a bit bigger than the default sitze of 176*166 I clicked "out of the Gui" and the items got thrown away. One mystery less in the world ^^

 

Appreciated your help Me
