[Solved-ish]Crafting Recipe: Returning an Item


Recommended Posts

I am currently attempting to add bacon to minecraft by adding a recipe using shears and a raw pork chop. I have successfully added the recipe and allowed it to return the shears to my inventory after crafting by using .setContainerItem, but I would like to be able to use shears of any durability and for the recipe to slightly lower the durability of the shears each time you craft. Thank you for your consideration.

You can add OreDictionary.WILDCARD_VALUE to the shears ItemStack itemdamage. This way any shears will do.

AFAIK, any item in a recipe will get damaged/removed when taking out the recipe output. It may depend on how you implemented the ContainerItem thing though.

Adding the wildcard value and reorganizing the ItemStack stuff (Originally I used the item itself in the crafting recipe, but now I am using the itemStack) did allow any shears to work in the crafting recipe, thanks! However, I am still unsure how to make the recipe damage the shears. Currently, if I use fully repaired shears and craft it with raw pork, I get raw bacon. However, it returns me shears undamaged. When I use already damaged shears and craft them in the recipe for bacon, it gives me raw bacon, but it returns me fully repaired shears. Currently with the .setContainerItem, I just have it set it to regular shears. It doesn't seem to allow me to add extra parameters to the .setContainerItem(Item.shears) and it does not except item stacks. Is there any way to fix it? Or is there an alternative method to returning shears? Thanks for your help.


Here's new relevant source:

        	ItemStack porkRawStack = new ItemStack(Item.porkRaw);
        	ItemStack shearStack = new ItemStack(Item.shears.setContainerItem(Item.shears), 1, OreDictionary.WILDCARD_VALUE);
               GameRegistry.addShapelessRecipe(new ItemStack(baconRaw),
        			porkRawStack, shearStack);

I don't know if a simple way to accept a container item of any durability and return a lower durability version, however, you can make the recipe behave any way you want before and after crafting by making your own class and extending net.minecraft.item.crafting.IRecipe and using your own logic, then registering the completed recipe.

How else can I allow it to return the shears though? I would not like to have to spend 2 iron every time I need bacon...

Do baconRaw.setContainerItem(Item.shears) then.


IRecipe is mostly to recognize a complex recipe that wouldn't be handled by Minecraft (like say, with ItemStack NBTTagCompound).

It doesn't tell what damage to apply to which item.

You need a ICraftingHandler to do that.

Goto Link, I think you are missing the point. I am trying to make shears and pork craft bacon. The whole point of .setContainerItem for me was so I didn't loose the shears when I craft bacon. If I use .setContainerItem(Item.Shears) for bacon, it would return shears when I craft with bacon, opposite of my goal. I either need to modify/extend minecrafts files to allow .setContainerItem to except parameters, or I need to find an alternative method to return shears to the crafting table or my inventory.

Since I am rather new to modding minecraft with forge, and to using java in general, I have decided to just create a knife that does not have a durability so I can easily just use .setContainerItem to make it return to me each time I craft. Thank you both for all of your help.
