Hey everyone,

 

I am working on a custom GuiContainer in 1.11.

I know that my problem is related to adding Slots to the Container.

 

I added the code for my Custom Container, if you think the problem is elsewhere I will post related files

 

public class ContainerBackpack extends Container{
	
	private final int HOTBAR_SLOT_COUNT = 9;
	private final int PLAYER_INVENTORY_ROW_COUNT = 3;
	private final int PLAYER_INVENTORY_COLUMN_COUNT = 9;
	private final int PLAYER_INVENTORY_SLOT_COUNT = PLAYER_INVENTORY_COLUMN_COUNT * PLAYER_INVENTORY_ROW_COUNT;
	private final int VANILLA_SLOT_COUNT = HOTBAR_SLOT_COUNT + PLAYER_INVENTORY_SLOT_COUNT;

	private final int VANILLA_FIRST_SLOT_INDEX = 0;
	private final int TE_INVENTORY_FIRST_SLOT_INDEX = VANILLA_FIRST_SLOT_INDEX + VANILLA_SLOT_COUNT;
	private final int TE_INVENTORY_SLOT_COUNT = 27;
	
	public ContainerBackpack(IItemHandler itemHandler, EntityPlayer player) {
		this.itemHandler = itemHandler;
		
		for (int l = 0; l < 3; ++l)
        {
            for (int j1 = 0; j1 < 9; ++j1)
            {
            	this.addSlotToContainer(new SlotItemHandler(itemHandler, j1 + l * 9, 8 + j1 * 18, 18 + l * 18));
            }
        }
		
		for (int i = 9; i < player.inventory.getSizeInventory()-5; i++) {
			addSlotToContainer(new Slot(player.inventory, i, 8 + i % 9 * 18,
					61 + 18 * (i / 9)));
		}
	}
	
	@Override
	public boolean canInteractWith(EntityPlayer playerIn) {
		
		return true;
	}

	public static ContainerBackpack build(EntityPlayer player, World world, int x, int y, int z) {
		ItemStack stack;
		if(x == 0) {
			stack = player.getHeldItem(EnumHand.MAIN_HAND);
		} else {
			stack = player.getHeldItem(EnumHand.OFF_HAND);
		}
		IItemHandler handler = stack.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY, null);
		return new ContainerBackpack(handler,player);
	}
	
	@Override
	public ItemStack transferStackInSlot(EntityPlayer playerIn, int index) {
		Slot sourceSlot = (Slot)inventorySlots.get(index);
		if (sourceSlot == null || !sourceSlot.getHasStack()) return null;
		ItemStack sourceStack = sourceSlot.getStack();
		ItemStack copyOfSourceStack = sourceStack.copy();
		
		if (index >= VANILLA_FIRST_SLOT_INDEX && index < VANILLA_FIRST_SLOT_INDEX + VANILLA_SLOT_COUNT) {
			// This is a vanilla container slot so merge the stack into the tile inventory
			if (!mergeItemStack(sourceStack, TE_INVENTORY_FIRST_SLOT_INDEX, TE_INVENTORY_FIRST_SLOT_INDEX + TE_INVENTORY_SLOT_COUNT, false)){
				return null;
			}
		} else if (index >= TE_INVENTORY_FIRST_SLOT_INDEX && index < TE_INVENTORY_FIRST_SLOT_INDEX + TE_INVENTORY_SLOT_COUNT) {
			// This is a TE slot so merge the stack into the players inventory
			if (!mergeItemStack(sourceStack, VANILLA_FIRST_SLOT_INDEX, VANILLA_FIRST_SLOT_INDEX + VANILLA_SLOT_COUNT, false)) {
				return null;
			}
		} else {
			System.err.print("Invalid slotIndex:" + index);
			return null;
		}
		
		if (sourceStack.getCount() == 0) {
			sourceSlot.putStack(null);
		} else {
			sourceSlot.onSlotChanged();
		}
		
		
		return copyOfSourceStack;
	}

}

You might want to take a look at this:

Your code looks way cleaner than mine Thank you!

Found the error, it was me only opening the GUI on Client-Side so yeah. Just me beeing stupid.
