I'm trying to make a 'sharpening stone', that when combined with any axe will add the efficiency 1 enchant to it. I've got a basic handler that returns the stone, but I can't figure out how to make the recipe use ANY kind of axe. Do I need to create an array of axes and reference that in the recipe? Here's what I have below.

 

	@SubscribeEvent
public void onCrafting(PlayerEvent.ItemCraftedEvent event)
{
	IInventory matrix = event.craftMatrix;
	ItemStack y = new ItemStack(ItemList.basicItem, 1);
	for(int i=0;i<matrix.getSizeInventory();i++)
		{
				if (matrix.getStackInSlot(i)!= null && matrix.getStackInSlot(i).getDisplayName().equals(y.getDisplayName()))
				{
					matrix.setInventorySlotContents(i, new ItemStack(ItemList.basicItem, 2));
				}
		}
}

 

public class ItemList {

public static Item basicItem;


public static void initItems()
{
	basicItem = new ItemBase();

	GameRegistry.registerItem(basicItem, "basicItem");

	GameRegistry.addShapelessRecipe(new ItemStack(Items.diamond_axe, 1), 
			basicItem, Items.wooden_axe, Items.flint);


}


}

Ok, thanks I'll have a look.

 

The ItemCraftedEvent is to give the item back after using it in the crafting recipe. There's probably a better way of doing it...

hasContainerItem and getContainerItem
