[1.8]Help with Custom Crafting Table and Recipes

Recommended Posts

I've got almost everything working correctly as a custom crafting table with its own recipes working,

except when the item crafted is picked up from the output slot, the itemstacks in the crafting matrix are never decremented.

This wasn't an issue in 1.7.2, but now it appears to be quite the problem.

 

Container Code:

 

public class ContainerKnappingStone extends Container
{
public InventoryCrafting craftMatrix;
public IInventory craftResult;
private World world;
private BlockPos pos;

private int verticalSlots = 5;
private int horizontalSlots = 5;

public ContainerKnappingStone(InventoryPlayer inventory, World world, BlockPos pos)
{
	craftMatrix = new InventoryCrafting(this, horizontalSlots, verticalSlots);
	craftResult = new InventoryCraftResult();
	this.world = world;
	this.pos = pos;

	//Output Slot
	this.addSlotToContainer(new SlotCrafting(inventory.player, craftMatrix, craftResult, 0, 140, 54));

	//Crafting Grid
	for(int y = 0; y < verticalSlots; y++)
	{
		for(int x = 0; x < horizontalSlots; x++)
		{
			this.addSlotToContainer(new Slot(craftMatrix, x + y * horizontalSlots, 8 + x * 18, 17 + y * 18));
		}
	}

	//Inventory
	for(int y = 0; y < 3; y++)
	{
		for(int x = 0; x < 9; x++)
		{
			this.addSlotToContainer(new Slot(inventory, x + y * 9 + 9, 8 + x * 18, 120 + y * 18));
		}
	}

	//Hotbar
	for(int x = 0; x < 9; x++)
	{
		this.addSlotToContainer(new Slot(inventory, x, 8 + x * 18, 178));
	}

	onCraftMatrixChanged(craftMatrix);
}

@Override
public void onCraftMatrixChanged(IInventory iinventory)
{
	craftResult.setInventorySlotContents(0, KnappingStoneCraftingManager.getInstance().findMatchingRecipe(craftMatrix, world));
}

@Override
public void onContainerClosed(EntityPlayer player)
{
	super.onContainerClosed(player);
	if(!world.isRemote)
	{
		for(int i = 0; i < verticalSlots * horizontalSlots; i++)
		{
			ItemStack itemstack = craftMatrix.getStackInSlotOnClosing(i);

			if(itemstack != null)
			{
				player.dropPlayerItemWithRandomChoice(itemstack, false);
			}
		}
	}
}

@Override
public boolean canInteractWith(EntityPlayer player)
{
	if(world.getBlockState(pos).getBlock() != SurvivalPlusBlocks.knapping_stone)
	{
		return false;
	}
	else
	{
		return player.getDistanceSq((double)pos.getX() + 0.5d, (double)pos.getY() + 0.5d, (double)pos.getZ() + 0.5d) <= 64.0d;
	}
}

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

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

		if(index == 0)
		{
			if(!mergeItemStack(itemstack1, 26, 62, true))
			{
				return null;
			}

			slot.onSlotChange(itemstack1, itemstack);
		}
		else if(index >= 26 && index < 53)
		{
			if (!mergeItemStack(itemstack1, 53, 62, false))
                {
                    return null;
                }
		}
		else if(index >= 53 && index < 62)
		{
			if (!mergeItemStack(itemstack1, 26, 53, false))
                {
                    return null;
                }
		}
		else if(!mergeItemStack(itemstack1, 26, 62, false))
		{
			return null;
		}

		if(itemstack1.stackSize == 0)
		{
			slot.putStack(null);
		}
		else
		{
			slot.onSlotChanged();
		}

		if(itemstack1.stackSize == itemstack.stackSize)
		{
			return null;
		}

		slot.onPickupFromSlot(player, itemstack1);
	}

	return itemstack;
}

}

I'm not sure if there is a callback somewhere that I'm missing, but when items are placed into the grid, the appropriate result appears in the output slot. I can take the item out of the output slot, but another one appears in the slot, and the items in the crafting grid do not get removed, or their stack size does not decrement.

 

When a shaped recipe is in the grid, it does decrement, but leaves itemstacks with size 0, that can still be picked up and used. If shift clicking on the output, it will fill the inventory with items, and still leave an itemstack of size 0 in the crafting grid.

 

When a shapeless recipe is in the grid, it doesnt decrement the itemstacks at all, and if shift clicking the output slot, it will cause a crash, from what I can tell, due to an infinite loop from Container.slotClick and Container.retrySlotClick

 

EDIT: Solved the problem crashing, now shaped recipes and shapeless recipes act the same way, never decrementing craftMatrix stacks causing an infinite number of items to be crafted.

 

Really not sure what to do here, any help would be truly appreciated.

Thanks.
