AtomiCoffe

Atomicoffe

Atomicoffe is a Fabric mod that embeds a full LuaJ scripting engine into your Minecraft server and client. Write scripts once, reload them live with /atomicoffe reload no restarts, no recompiling, no Java required.

What can you do with it?

• Custom commands register Brigadier commands directly from Lua
• Event hooks react to player join/leave/death, block interactions, entity kills, chat, ticks, and more
• Recipes add or modify shaped and shapeless crafting recipes at runtime
• Loot tables inject drops into any vanilla loot table
• Scoreboard create objectives and read/write scores from scripts
• Per-player persistent data save and load arbitrary key/value data per player UUID
• Scheduling run callbacks after N ticks or on a repeating interval
• Networking send custom packets between server scripts and client scripts
• Tags add items/blocks to vanilla tags at startup (affects recipes, mechanics, etc.)
• Mob effects apply, remove, and query potion effects from Lua
• Client HUD draw text and rectangles on the player’s screen
• Client keybinds register keybinds that trigger Lua callbacks or send packets to the server

Script Phases

| Folder | When it runs |
|——–|————-|
| startup_scripts/ | Before the server starts for tag/registry changes |
| server_scripts/ | When the server starts and after every /reload |
| client_scripts/ | On the client HUD, keybinds, client-side events |

All scripts live in your instance’s config/atomicoffe/ folder and are hot-reloadable.

Quick Example

-- config/atomicoffe/server_scripts/welcome.lua

onEvent("player.join", function(e)
  e.player.tell("§aWelcome, §e" .. e.player.name .. "§a!")
  e.player.give("minecraft:bread", 8)
end)

command.register("ping", function(ctx)
  ctx.reply("Pong! TPS: " .. server.getTps())
end)

schedule.every(6000, function()  -- every 5 minutes
  server.broadcast("§b[Info] §fNeed help? Check our Discord!")
end)
