Minecraft 1.13 data pack override default loot tables

minecraft-java-edition

Very recently a new minecraft snapshot has come out. The snapshot introduced data packs, basically a folder with custom functions, recipes, loot tables and more.

I wanted to try this out and see if I could change the default loot table of a guardian. This is how the pack looks:

d_invpack
-pack.mcmeta
-data
    -d_invpack
        -loot_tables
            -entities
                -guardian.json

My custom loot table should make guardians drop sponges.

I loaded this in my fresh 1.13 world (17w43b), I spawned a guardian with a spawn egg and killed it with the kill command. I didn't get a sponge, but the default loot.

I found out that if I applied the loot table with the command /entitydata @e[type=guardian] {DeathLootTable="d_invpack:entities/guardian"}, the guardian does drop a sponge, so the pack and table work, but it hasn't overridden the default table.

I was told that I should use the minecraft namespace to override the default loot tables, so I changed my folder structure to this:

d_invpack
-pack.mcmeta
-data
    -minecraft
        -loot_tables
            -entities
                -guardian.json

I tried again, but still no luck. The guardian dropped the default loot. I have used the /reload command to make sure that the pack is loaded correctly, so that is not the problem. I can't alter the loot table of the guardian using commands this time, because "minecraft:entities/guardian" refers to the default table, even if I specified it in my data pack.

Can I override the default loot tables with a data pack? And how?

I tried this again in the latest snapshot (17w48a) and now it works just fine. Data packs were just out at the time that I posted this question and it was a bug. In the latest snapshot, this works just fine, provided that this datapack is loaded after the vanilla datapack.

I can't do it with loot tables, but I can still help you. Get a repeating command block and input:

/scoreboard objectives add test stat.killEntity.WitherSkeleton

Next, in the same direction as that command block is facing, place a chain command block and input this:

execute @p[score_test_min=1] ~ ~ ~ summon minecraft:wither_skull ~ ~ ~

which is good if your inventory is filling up fast, or

give @p[score_test_min=1] minecraft:skull 1 1

which is great if you're on a server and don't want people pinching your skulls. Next place another chain command block with:

/scoreboard players set @p[score_test_min=1] test 0

Note: Replace 'test' with the name of a scoreboard of your choosing, set the repeating command block to always active and unconditional, set the others to always active and conditional. This is multiplayer-friendly.

Bonus: If you use this for something more common (like cows and leather, for example), you might want to limit the availability by imposing a second requirement. To do this, put another repeating command block in place. Whichever repeating command block is closest to the chain command blocks can be a chain command block, but it must be set to conditional.

An example of a different kind of restriction is:

{SelectedItem:{id:minecraft:iron_axe,tag:{display:{Name:"Sacrificial Axe"}}}}

Best of luck!

Minecraft – the path for Loot Tables in Minecraft 1.13

You need to create a so called datapack. A datapack is a folder structure that contains recipes, advancements, loot tables and more.

These are the steps for your loot table:

Go to .minecraft/saves/yourworld/datapacks
Create a folder with a name of your choice. I recommend a name without spaces or special characters. This is your datapack name
Inside that folder, create a pack.mcmeta file, similar to a resource pack and a folder called data.
Inside the data folder, create a folder with a name of your choice. This will be your namespace. If you name this folder minecraft, then you can overwrite the default loot tables in minecraft if you want.
Inside the namespace folder, create a folder called loot_tables.
Inside the loot_tables folder, you can place your loot tables. You are allowed to add additional folders here to organise your loot tables.

Now you can use your loot table in minecraft. To access it, you specify the path as follows: namespace:path/to/loottable, where namespace is the namespace that you defined. The path starts from inside the loot_tables folder.

This is what the content of pack.mcmeta looks like:

{ 
    "pack": 
    { 
        "pack_format": 1,
        "description": "Tutorial Data Pack"
     } 
}
