Like wheat and seeds in vanilla, how can I give an item the ability to breed animals?

This is actually code in the Entity, not the Item.  If you have a new custom animal that you want your custom item to be able to put into "breeding mode" you would override isBreedingItem in your entity's class.  If you want a custom item to work on preexisting entities you would have to hook into the EntityInteract event.

The Item class should already have an OnEntityInteract method (can't remember the exact name, but is used by a few items like shears) that you can use. You'd then want to call entity.setInLove(player). (Maybe it takes the stack? Looking at old code where I was doing it from an AI task, so I was passing null).

Well crap.  There is one.  It's called onInteractionForEntity.  Welp, I need to go change some code..

Thanks, I got that the breeding to work. What about making the item attract animals while being only held in your hand?

You might have to make an AI task for that. Check how vanilla handles it already.

private static final Set<Item> TEMPTATION_ITEMS = Sets.newHashSet(Items.CARROT, Items.POTATO, Items.BEETROOT);
  
   protected void initEntityAI()
    {
        this.tasks.addTask(4, new EntityAITempt(this, 1.2D, false, TEMPTATION_ITEMS));
    }

 

Just to clarify, I did not make a custom entity. I'm trying to tempt vanilla animals.

 

With this in mind, here is a snippet of the code from the EntityPig class. To add my item to TEMPTATION_ITEMS, will I need to create myself a new EntityPig class with my item inside the set? Or how do I go about modifying this?

 

 

Remove that AI task and recreate it with a new list.

Would it also be an option to replace the Item Set with one of your own choice via reflection?
