How do I add an empty item to a loot table?

[skeddles]

I want to make it a chance that you get no item from my loot table. I adding the items dynamically, not grabbing them from a json file. How can I add a blank item? Only thing I've found is ItemStack.EMPTY but LootEntryItem wants an Item not an Itemstack.

 

part of my code:

 

ArrayList<LootEntryItem> entries = new ArrayList<LootEntryItem>();

entries.add(new LootEntryItem(abcmExcalibur, 10, 60, new LootFunction[0], new LootCondition[0], "heroicarmory:abcmExcalibur"));

LootEntry [] entriesArray = entries.toArray(new LootEntry[entries.size()]);

LootPool pool = new LootPool(entriesArray, new LootCondition[0], new RandomValueRange(1), new RandomValueRange(1), "heroicarmorypool");

evt.getTable().addPool(pool);

 

does not work:

entries.add(ItemStack.EMPTY ,new LootEntryItem(null, 1169, 60, new LootFunction[0], new LootCondition[0], "heroicarmory:empty"));

You can't. The point of loot tables is to generate something when the dice roll up sixes. If you want it to be a Sometimes thing, look at how vanilla handles iron golem roses.
