For live Roblox games

Change your live game without shipping an update.

Features, player data, moderation and releases, declared in your code and run from one console.

A feature declared in Luau with a typed config, and the same feature in the console

Seasonal.luau

local Seasonal = Control.Scope("Seasonal"):Feature():Config({
  Theme = Control.Config(Theme, { Default = "none" }),
})

Seasonal:OnActivate(function(keeper)
  keeper:Add(DressLobby(Seasonal.Theme:Get()))
end)

A player's save declared with its own rules, and the console changing it through one

Profile.luau

local Profile = Control.Scope("Profile"):Entity({
  KeyedBy = "Player",
  State = State,
  Default = { Coins = 100, Level = 1 },
})

Reducers.AddCoins = Profile.Writes({ Amount = Amount })
  .Then(function(state, fields)
    return { Coins = state.Coins + fields.Amount }
  end)

A kick declared as a command, and the console running it on one player

PlayerCommands.luau

Kick.Now = Control.Command({ Reason = Reason })
  .Label("Kick Player")
  .Tier("routine")
  .Handles(function(directive)
    local id = tonumber(directive.target)
    local player = Players:GetPlayerByUserId(id)
    player:Kick(directive.params.Reason)
    return true
  end)

A command declared for servers, and the console sending it to every server at once

Server.luau

Server.Fireworks = Control.Command({ Bursts = Bursts })
  .Label("Launch fireworks on this server")
  .Tier("routine")
  .PerServer()
  .Handles(function(directive)
    Launch(directive.params.Bursts or 10)
    return true
  end)

A developer product made with the CLI, its receipt declared with what it grants and how a refund is undone, and the console proposing that reversal

Receipts.luau

-- craftsman store add --name "Golden Pickaxe"
golden_pickaxe = {
  Grants = Control.Op(Player.Inventory, "GrantItem",
    { ItemId = "golden_pickaxe", Amount = 1 }),
  Reverse = Control.Op(Player.Inventory, "RemoveItem",
    { ItemId = "golden_pickaxe", Amount = 1 }),
},

Commerce.Prompt(player, "golden_pickaxe")
