So i'm trying to add items and blocks to vanilla dungeon chests using the LootTableLoadEvent. But i don't understand much of how to add them. I know i have to do this

event.getTable().addPool(new LootPool(new LootEntryItem(itemIn, weightIn, qualityIn, functionsIn, conditionsIn, entryName), poolConditionsIn, rollsIn, bonusRollsIn, name));

but i didn't understand what to place instead of parameters. Also how can i add a sub block to the loot, because from the Item.getItemFromBlock i get only the default value of the block

 

To set the metadata of the item, you need to create an instance of the

SetMetadata

function and include it in the

LootFunction

array parameter of the

LootEntryItem

constructor. For damageable items like tools, use the

SetDamage

function instead.

 

The parameter names mostly correspond to the JSON format, which is explained here.

Thank you That works, but i want to know if i can improve my code. Right now i have this

@SubscribeEvent
public void onLootTableLoad(LootTableLoadEvent event) {
	ResourceLocation name = event.getName();
	LootTable table = event.getTable();
	LootCondition[] chance = {new RandomChance(50.0F)};
	LootFunction[] count = {new SetCount(chance, new RandomValueRange(1.0F, 4.0F))};
	LootFunction[] meta = {new SetMetadata(chance, new RandomValueRange(0.0F, 1.0F))};
	LootEntryItem[] item = {new LootEntryItem(MWItems.ruby, 50, 1, count, chance, "ruby")};
	LootEntryItem[] log = {new LootEntryItem(Item.getItemFromBlock(MWMetadataBlocks.log), 50, 1, meta, chance, "log")};
	if(name.equals(LootTableList.CHESTS_SPAWN_BONUS_CHEST)) {

		table.addPool(new LootPool(item, chance, new RandomValueRange(1.0F), new RandomValueRange(0.0F), "ruby"));
		table.addPool(new LootPool(log, chance, new RandomValueRange(1.0F), new RandomValueRange(0.0F), "log"));
	}
}

 

wich i think is not the best code (expecially the randomChanceValue)

Are you sure you want to add a new pool for each item rather than adding the items to an existing pool?

 

I'd recommend checking the name before you create any objects so they're only created when they need to be used.

 

The value of the

RandomChance

condition should be between 0 and 1 (0% and 100%). Anything over 1 will always be true.

 

I'd recommend separating out the values (conditions, functions, etc.) used by both entries and grouping the values only used by one entry with that entry.

Thanks for the explanation, i'll group all items into one array and add that, and also lowering the randomChance value to something valid (like 0.5)
