}Command
/loot give @s loot example:chests/treasure42 characters
For Java Edition 26.3. Every form this tool writes was run through the game's own command parser.
Or a chest that fills itself when first opened: /setblock ~ ~ ~ chest{LootTable:"example:chests/treasure"}
Item modifiers the builder writes
| set_count | How many: a number or from-to |
| enchant_randomly | One random enchantment the item can take |
| enchant_with_levels | Enchants like an enchanting table at these levels |
| set_enchantments | These enchantments at these levels |
| set_damage | Durability left, 0 to 1 |
| set_name | A name for the item |
How the game works it out
| File | A loot table goes into a data pack at data/<namespace>/loot_table/<path>.json and is called by its id, like example:chests/treasure |
| Format in 26.3 | An entry's functions are written as modifier, one object or a list, and conditions as condition with a type |
| Rolls | Each roll keeps the entries whose conditions pass and picks one of them by weight; from-to rolls are a whole number drawn evenly |
| Chance | A random_chance on an entry is drawn again for every roll; on a pool it decides whether the pool is rolled at all |
| Using it | /loot give @s loot <id> gives the items now; a chest with LootTable fills itself the first time it is opened |
| Checked in the game | Every table the builder can write was loaded in a data pack and dropped in the game |
