Hello everyone!

In my GUI i have two slots, one for input and one for output like this:

But when i open the GUI, the input slot is filled with the Item i have in the second hotbar slot.

I think that the problem is in the container code, here it is:

public class CompactorContainer extends Container{

	private CompactorTileEntity te;

    public CompactorContainer(IInventory playerInventory, CompactorTileEntity te) {
        this.te = te;

        addOwnSlots(playerInventory);
        addPlayerSlots(playerInventory);
    }

    private void addPlayerSlots(IInventory playerInventory) {
        for (int row = 0; row < 3; ++row) {
            for (int col = 0; col < 9; ++col) {
                int x = 8 + col * 18;
                int y = row * 18 + 84;
                this.addSlotToContainer(new Slot(playerInventory, col + row * 9 + 10, x, y));
            }
        }

      //add the slots for the hotbar
        for (int col = 0; col < 9; ++col) {
            int x = 8 + col * 18;
            int y = 72 + 70;
            this.addSlotToContainer(new Slot(playerInventory, col, x, y));
        }
    }

    private void addOwnSlots(IInventory pInv) {
        addSlotToContainer(new Slot(pInv, 1, 48, 34));
        addSlotToContainer(new Slot(pInv, 1, 110, 35));
    }

    @Override
    public ItemStack transferStackInSlot(EntityPlayer playerIn, int index) {
        ItemStack itemstack = ItemStack.EMPTY;
        Slot slot = this.inventorySlots.get(index);

        if (slot != null && slot.getHasStack()) {
            ItemStack itemstack1 = slot.getStack();
            itemstack = itemstack1.copy();

            if (index < CompactorTileEntity.SIZE) {
                if (!this.mergeItemStack(itemstack1, CompactorTileEntity.SIZE, this.inventorySlots.size(), true)) {
                    return ItemStack.EMPTY;
                }
            } else if (!this.mergeItemStack(itemstack1, 0, CompactorTileEntity.SIZE, false)) {
                return ItemStack.EMPTY;
            }

            if (itemstack1.isEmpty()) {
                slot.putStack(ItemStack.EMPTY);
            } else {
                slot.onSlotChanged();
            }
        }
        return itemstack;
    }
	
    @Override
    public boolean mergeItemStack(ItemStack stack, int start, int end, boolean reverse){
    	return super.mergeItemStack(stack,start,end,reverse);
    }
    
	@Override
	public boolean canInteractWith(EntityPlayer playerIn) {
		return te.canInteractWith(playerIn);
	}

}

Thanks you all!

Why are the indices of both of your slots the same? This should never be the case.

As for the issue - look at the object you are passing to this method:

Obviously the added slots will correspond to the player's inventory since it is the inventory you are passing.

So i must create a personal slot, right?

Grammar correction

You need to give the slots that belong to your TE's inventory said TE's inventory, not the player's inventory.
