Loot table

Loot tables are technical JSON files that are used to dictate what items should generate in various situations, such as what items should be in naturally generated containers, what items should drop when breaking a block or killing a mob, what items can be fished, and more. It does not affect dropped experience, or dropped non-item entities such as slimes from larger slimes or silverfish from infested blocks.

Usage
The loot tables are structured as a String tag that determines the table to use, and a Long tag determining the seed. Containers or mobs with the same seed and table drop the same items. Loot tables do not determine the container's slot to be used; that is randomly determined based on the seed.

For chests, trapped chests, hoppers, storage minecarts, minecarts with hoppers, dispensers, droppers, shulker boxes and barrels: These tags are removed once the items have been interacted with (by opening the container, breaking the container, etc.), and only then are items put in the container.
 * : Loot table to be used to fill the container when it is next opened, or the items are otherwise interacted with. When the container is a chest that is part of a double chest, only the half corresponding to the tagged single-chest is affected.
 * : Seed for generating the loot table. Works similarly to the seeds for worlds. 0 or omitted uses a random seed.
 * : Seed for generating the loot table. Works similarly to the seeds for worlds. 0 or omitted uses a random seed.

For mobs:


 * The root tag.
 * : Loot table to be used for the items that drop when the entity is killed.
 * : Seed for generating the loot table. Works similarly to the seeds for worlds. 0 or omitted uses a random seed.

The loot tables of mobs and containers can be altered with and. The player could also grant a loot table to an entity or drop it in the world with.

Conditions
Loot tables use various conditions that add requirements to a drop, pool, or function. Below are a list of valid conditions, and the tags used by them. The tags are placed in the same condition object as.

Moreover, the conditions from directory in the   directory in data packs have the same structure as the loot conditions.

See predicate for the possible conditions.

List of loot tables
Below is a list of all loot tables that exist by default. More tables can be added in the world save for use with custom maps. Note that some blocks, such as bedrock, end portals and other blocks unbreakable in survival do not have loot tables, some blocks share loot tables (namely wall and floor variants of blocks) and that certain drops, namely head drops from charged creepers and the wither's nether star, are currently not covered by loot tables.

Data packs
Custom data packs use loot tables to change what loot can spawn in containers or drop by mobs. They can either change existing loot tables or create new ones. This is the file structure:


 * world save folder
 * datapacks
 * data pack
 * data
 * minecraft
 * loot_tables
 * See
 * custom_namespace
 * loot_tables
 * loot table name.json

The JSON files go in this folder. Vanilla loot tables are grouped into 4 categories: gameplay (fishing), entities, blocks, and chests, with some tables being in subfolders of those. For example, the file for zombies would go in. This makes every zombie in that world use the datapack's loot table rather than the default zombie loot table.

Loot tables are namespaced. To create a custom loot table, first create a new folder for the custom namespace, and then create loot tables within following a similar structure. Then, summon the mob with the data tag DeathLootTable set to the name of the directory and file (without the .json extension), such as.
