Could someone please explain how to edit a mob's drop chance of an item or how to add an item to their loot table?

Even better, tell me how to use those other crazy tags, like enchant_randomly or furnace_smelt.

The default loot tables are located in assets\minecraft\loot_tables within your Minecraft jar. Find the one you want to alter (e.g: entities\creeper.json) then copy it to data\loot_tables\minecraft\... (create the folders if they don't exist) in your world folder:

Overwriting creeper loot table

The first folder after data\loot_tables is called a "namespace" and loot tables must all be within one (you cannot place a loot table directly into data\loot_tables). In this case I'm using the minecraft namespace to overwrite the creeper's loot table.

If you don't want to overwrite the default drops for all of a certain type of mob, but instead want to summon specific mods with this new loot table, you should place the loot tables into another namespace, such as realordsloottables.

If you open up the loot table, it should look something like this:

Loot table

If you want to edit these manually, I'd recommend looking at some of the default ones for examples, and reading this wiki page. There's a lot of things you can do and it's all already documented there.

To manually add a new item, you could copy paste the item already in this pool, and change its name. Here, I've given the creeper a possibility to drop between 16 and 32 stone:

Loot table edited

I'd recommend using a generator to simplify the process, then copy and pasting the output into the loot table:

After changing and saving the loot table, the mob's drops should now be changed. If you saved it in a custom namespace because you want it to only affect certain mobs, then you should summon the mobs like this:

/summon Zombie ~ ~ ~ {DeathLootTable:"namespacename:folder/loottablename"}
  • The linked generator is outdated as well as missing a large number of features that are key to using loot tables (I list out the issues with it here). This generator, while not as visually-appealing, is both up-to-date and feature-complete.

  • @Skylinerw Added that generator to the post (and bookmarked for future use). Wonder if there's a way to contact the creators of Minecraft.Tools, since some of those problems (like the incorrect weight min) seem like they could be easy fixes.

  • I'm not sure where to find assets\minecraft\loot_tables or data\loot_tables\minecraft. Help!

  • Do I need to worry about pools or rolls or weight?

  • @ReaLord If you want it to come with your map, put it in assets\minecraft\loot_tables. If you want it to affect every map, put it in data Aug 27, 2016 at 2:56
