I am trying to make an item that lets you breed any 2 animals of the same type without it costing a thing. So for example, how you would breed two cows with wheat, you would only have to use this one item and it would cost nothing. Problem is, I have no clue on how to do that. There are no tutorials on how to do something remotely similar to what I am trying to accomplish. I was wondering if someone from here could help me out.
