Custom Player Head Crafting Recipes?

[KansasToYou]

Hello, is it possible to make a crafting recipe that requires a certain player's head? Like if you wanted to create a special type of block, it'd require Notch's player head. If you could include the exact code to do so, that'd be extremely appreciated. Thanks.

The owner of the skull is stored in the NBT, but vanilla recipes ignore the NBT of ingredients.

 

You'd need to make your own recipe class that implements

IRecipe

and checks the NBT of the ingredients in addition to the

Item

and metadata.
