DATAPACK GENERATOR
Describe a Minecraft datapack in plain English. Codexe writes the .mcfunction files, advancements, loot tables and recipes. Pure vanilla, no mod loader needed.
Why generate datapacks with AI
Vanilla, zero deps
Drop the folder in <world>/datapacks/, run /reload, done. No mod loader, no plugin, no Java required to run.
Modern command syntax
Execute store, predicate selectors, function tags, item components, the generator uses current syntax for the version you specified.
Advancement trees done right
Hidden advancements, parent chains, custom frames, display titles, multiple triggers per advancement. Reward functions wired automatically.
Loot tables & recipes
Drop chances with proper functions, conditions, rolls. Shaped, shapeless, smelting, smithing transform recipes. Item modifiers for the new component system.
Iterate by chat
"Add a 5% chance to also drop a diamond". "Make the function repeating, every 5 ticks". The AI edits the pack in place.
You own everything
Source folder is yours. Share on Planet Minecraft, sell on PMC market, use on your realm. No royalties.
Example datapack prompts
From a single recipe override to a multi-feature gameplay tweak pack. Some real prompts you can paste:

“On craft of a Heart of the Sea, give the player a Totem of Undying with custom_name 'Sea Totem' and custom_data {sea_totem:true}. When triggered, also fill nearby 5-block radius with conduit power for 30s.”
Tree of advancements: 'Speedrunner'
“A 5-step advancement tree titled 'Speedrunner': enter Nether, locate Stronghold, kill Ender Dragon, do all in under 30 minutes, do all without dying. Last two are hidden until Dragon kill.”

Anti-AFK farms
“A repeating function that detects players standing still for over 30 seconds in spawn chunks and teleports them to spawn with a chat message.”
