Change mob loot table and experience on spawn

[Insane96MCP]

I want to make a mob (wither skeleton) drop nothing (so set the loot table to empty) and drop no experience too.

There's any way to change those?

You can set the EntityLiving#deathLootTable field using reflection to change an entity's loot table. You can also subscribe to LivingDropsEvent to change the item dropped by an entity.

 

You can set the EntityLiving#experienceValue field using reflection to change the amount of experience dropped by an entity, though some entities set this field after the initial spawn (e.g. Baby Zombies do this on death). You can also subscribe to LivingExperienceDropEvent to change the amount of experience dropped by an entity.

You can also use the LootTableLoadEvent to modify the loot table.

Though it should be noted that this affects the loot table globally rather than for just a single entity.

The original question is a bit ambiguous, but I read it as he wants to replace the loot globally for wither skeletons. In the event you get the name of the resource which would let you filter to only change the wither skeleton loot.

But this will be pretty useful for another mod.

Thanks all

Just two questions

Why?

And I can use my loot tables by putting them in resources/mod_id/loot_tables/whatever_folder_I_want?

So that Baby Zombies drop roughly 2.5x more experience from the super call in EntityZombie#getExperiencePoints.

If you mean assets/<mod_id>/loot_tables/..., then yes.

There's no way to change ender dragon experience drop?

Yep, my stupid brain was thinking: "You can't since he drops experience over time"

I did it, but minecraft seem to not like my loot tables
I've placed a file in assets/progressivebosses/loot_tables/dragon_minion.json. The json is valid (copy paste of squid loot table).
Then used deathLootTable.set(shulker, new ResourceLocation("progressivebosses:dragon_minion"));

But the shulker drops nothing ...

Actually you can't. The LivingExperienceDropEvent is not called for the ender dragon :c

Are there any errors in the log?

 

Try setting breakpoints in EntityLiving#dropLoot, LootTableManager#getLootTableFromLocation and LootTableManager.Loader#load and stepping through them when a Shulker dies.

I had to register the loot table and add the "name" field to the loot table (but I don't know which one of those fix resolved my problem)
