Localization - Developer Suite

Copy resolves through the localization layer, while data like numbers, keys, and hex codes is left alone. English is the source, and each English string is its own key, so a translation table only lists the strings you change. Anything you skip stays in English, and a regional id like pt-br beats the bare pt. With no locale given, the window follows the player’s Roblox language on its own.

Translation tables

Pass tables keyed by locale id.

Rayfield:CreateWindow({
    name = "Example",
    translations = {
        fr = { ["Auto Sprint"] = "Sprint auto", ["Signed in as"] = "Connecté en tant que" },
        es = { ["Auto Sprint"] = "Sprint automático" },
    },
})

Switch languages live, with no rebuild.

window:SetLocale("fr")

Add a pack at runtime.

window:RegisterTranslations({ de = { ["Auto Sprint"] = "Auto-Sprint" } })

A custom resolver

To resolve copy yourself, pass a translator. It is a function (source, localeId) that returns a string, or nil to fall through to the tables. It is checked first, so it wins.

Rayfield:CreateWindow({
    name = "Example",
    translator = function(source, localeId)
        return myTranslationService(source, localeId)  -- or nil to fall back
    end,
})

Swap it at runtime with window:SetTranslator(fn), then re-apply the locale to refresh the screen.
