1.10.2 How to add Loot tables for mobs

[TheRPGAdventurer]

Hi everyone,

      I wondered why my mob doesn't drop anything, so I used the loot tables for the sheep and it works, I returned to the webpage where I learned to make loot tables it turns out it was posted 5 years ago, HAHA Idiot me, so I was looking for a tutorial on making custom loot tables thanks a bunch.

1. Make sure that your loottable is a valid json and has proper syntax (name property defined)
2. Place it somewhere within assets/modid/loot_tables/
3. Get a ResourceLocation pointing to it in your core. It should point to your loottable file, but it should not include the path up to loot_tables folder and the extension. 
4. Obtain a registry ResourceLocation using LootTableList::register
5. Double check that your ResourceLocation is correct, your json is correct, etc.

That ResourceLocation you obtain in step 4 is what you need.

Refer to this topic for more details and examples:

It is a very recent one too, so all the information there is up to date.

 

Another related topic I've found:

loottable file, location and syntax example.

And registration example.

I've changed those files since posting in that other thread, you can see the latest versions (as of the writing of this post) here:

 

Loot table file

Loot table registration

 

For anyone reading this thread in the future, you can use the Tree/Branch/Tag dropdown on GitHub to see the latest versions of these files on each branch. The branches are currently named after the Minecraft version they're targeting.

Do I have to extend my lootable list to minecraft's LootTableList?

[V0idWa1k3r]

You do not need to extend anything anywhere. Look at the examples Choonster graciously provided

Here is one of the lootables, I based with sheep's. https://pastebin.com/BeJD1GQN

Your json has no name property defined for your pools. Forge requires that property to be defined for mod loottables.

So you're telling me that minecraft van put anything without name property but modders need to?

[V0idWa1k3r]

Erm, yes

Yes. Forge adds the naming requirement for mod loot tables and auto-generates names for vanilla loot tables.

You need to specify a name for each pool in the loot table file. I explained the naming requirements here (in the thread that @V0idWa1k3r linked).

 

Please use code blocks (the <> icon in the editor) when posting code. Alternatively, use Gist/Pastebin.

I did, I mean in the loot table class.

I'm talking about the loot table JSON file, not the class that registers the loot tables.

So there's nothing wrong in the class I made?

The class looks correct, but make sure you call RealmOfTheDragonsLootTables.registerLootTables in preInit.

You didn't name the second pool.

There are two loot pools in that file, one that includes an entry for the rotd:amethsyt_dragon_scales item and one that includes an entry for the rotd:entities loot table. Only the first has a name.

Wait, you don't need to register it just like minecraft's loottablelist and the location is in the JSON itself?

You're registering the loot table correctly, but it's the contents of the JSON file that need to fixed.

 

Each loot pool in the loot table JSON file needs to have a "name" property with a unique value. Currently only the first of the two loot pools has a "name" property.

I actually based on the sheep's the second pool never existed and what probably causing the bug.

That looks correct. Are there any errors in the log?

 

Post your loot table registration class and your entity class.
