[1.14.4][SOLVED] Editing LootTables with LootTableLoadEvent

[Boy132]

So I found this LootUtils class from Draco18s and edited it so I could also add Items to LootTables. If I run my mod within eclipse (runClient) it all works but if I build the mod and use it in my normal minecraft all block do not drop anything.

Here's the LootUtils code:

Spoiler

public class LootUtils
{
	private static Field tablePools;
	private static Field poolEntries;
	private static Field entryItem;

	static
	{
		tablePools = ObfuscationReflectionHelper.findField(LootTable.class, "pools");
		tablePools.setAccessible(true);
		poolEntries = ObfuscationReflectionHelper.findField(LootPool.class, "lootEntries");
		poolEntries.setAccessible(true);
		entryItem = ObfuscationReflectionHelper.findField(ItemLootEntry.class, "item");
		entryItem.setAccessible(true);
	}
	
	public static boolean removeLootFromTable(LootTable table, Item toRemove)
	{
		try
		{
			List<LootPool> pools = (List<LootPool>) tablePools.get(table);
			
			for(LootPool pool : pools)
			{
				List<LootEntry> entries = (List<LootEntry>) poolEntries.get(pool);
				Iterator<LootEntry> iterator = entries.iterator();

				while(iterator.hasNext())
				{
					LootEntry entry = iterator.next();

					if(entry instanceof ItemLootEntry)
					{
						ItemLootEntry itemLootEntry = (ItemLootEntry) entry;
						Item item = (Item) entryItem.get(itemLootEntry);

						if(item == toRemove)
						{
							iterator.remove();
							return true;
						}
					}
				}
			}
		} catch(Exception exception)
		{
			exception.printStackTrace();
			return false;
		}
		
		return false;
	}

	public static LootPool createLootPool(String name, RandomValueRange numRolls, RandomValueRange bonusRolls, LootEntry.Builder entryBuilder, ILootCondition.IBuilder conditionBuilder, ILootFunction.IBuilder functionBuilder)
	{
		LootPool.Builder builder = LootPool.builder();
		builder.name(name);
		builder.rolls(numRolls);
		builder.bonusRolls(bonusRolls.getMin(), bonusRolls.getMax());
		builder.addEntry(entryBuilder);
		builder.acceptCondition(conditionBuilder);
		builder.acceptFunction(functionBuilder);
		
		return builder.build();
	}

	public static void addItemToTable(LootTable table, LootPool pool)
	{
		table.addPool(pool);
	}

	public static void addItemToTable(LootTable table, Item item, int weight, float probability, int minQuantity, int maxQuantity, String name)
	{
		addItemToTable(table, item, weight, 1, probability, minQuantity, maxQuantity, name);
	}

	public static void addItemToTable(LootTable table, Item item, int weight, float probability, int quantity, String name)
	{
		addItemToTable(table, item, weight, 1, probability, quantity, quantity, name);
	}

	private static void addItemToTable(LootTable table, Item item, int weight, float numRolls, float probability, int minQuantity, int maxQuantity, String name)
	{
		RandomChance.IBuilder conditionBuilder = RandomChance.builder(probability); 
		SetCount.IBuilder functionBuilder = SetCount.func_215932_a(new RandomValueRange(minQuantity, maxQuantity));
		
		ItemLootEntry.Builder entryBuilder = ItemLootEntry.builder(item);
		entryBuilder.weight(weight);
		entryBuilder.quality(1);
		entryBuilder.acceptCondition(conditionBuilder);
		entryBuilder.acceptFunction(functionBuilder);
		
		LootPool newPool = createLootPool(name, new RandomValueRange(numRolls), new RandomValueRange(0), entryBuilder, conditionBuilder, functionBuilder);
	
		addItemToTable(table, newPool);
	}

 

And my Event:

Spoiler

private static final ResourceLocation STONE = new ResourceLocation("blocks/stone");

@SubscribeEvent
public void onLootTableLoad(LootTableLoadEvent event)
{
  LootTable table = event.getTable();
	
  if(event.getName().equals(STONE))
  {
    LootUtils.removeLootFromTable(table, Item.getItemFromBlock(Blocks.COBBLESTONE));
    LootUtils.addItemToTable(table, ItemRegistry.ROCK, 10, 1f, 2, 4, "rock");
  }
}
