Modifying NBT on crafting

[Asweez]

I have an item with NBT that I want to change when it is crafted with certain items. How would I do this?

That depends on what exactly you are tring to do. If its something simple like increment a value you can make it a container item. Otherwise you will probably need a custom IRecipe class.

What?

 

I would use a crafting event.

Ähm, I am pretty sure that I am changing the outcome in my event handler with an ItemCraftedEvent.

I use it to add poisons (=nbt tags) to all food items.

Yeah, but he just wants to change some nbt tags, so I doubt that there will be rendering errors.

And it worked fine for me no matter which crafting table I used.

I solved it. All I had to do was make a new item stack with my item, add the NBT tag to it, then add the recipe with the output being the item stack that I created.
