Change mob loot table and experience on spawn


Insane96MCP

Recommended Posts

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.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

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.

That's what I wanted

But this will be pretty useful for another mod.

Thanks all

Why?

 

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

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

 

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

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

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 ...

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)

    • Hey, Me and my friends decided to start up a Server with "a few" mods, the last few days everything went well we used all the items we wanted. Now our Game crashes the moment we touch a Lava Bucket inside our Inventory. It just instantly closes and gives me an "Alc Cleanup"  Crash screen (Using GDLauncher). I honestly dont have a clue how to resolve this error. If anyone could help id really appreciate it, I speak German and Englisch so you can choose whatever you speak more fluently. Thanks in Advance. Plus I dont know how to link my Crash Report help for that would be nice too whoops
    • I hosted a minecraft server and I modded it, and there is always an error on the console which closes the server. If someone knows how to repair it, it would be amazing. Thank you.
