Roblox Localization

When to Load

Load when implementing multi-language support, translation systems, locale-specific content, or region detection. Covers LocalizationService, LocalizationTable, auto-translation, and country/region detection.

Quick Reference

Locale Detection

• player.LocaleId: locale the player set for their Roblox account (e.g. en-us, pt-br, ja-jp)
• LocalizationService.RobloxLocaleId: locale for core/internal features
• LocalizationService.SystemLocaleId: player's OS locale
• LocalizationService:GetCountryRegionForPlayerAsync(player): country code from IP geolocation (e.g. US, BR, JP)

Translation Tables

• LocalizationTable: stores translation entries (key → translations per locale)
• Parent LocalizationTable under LocalizationService for auto-translation
• Set GuiBase2d.RootLocalizationTable on GUI objects for per-element tables
• Studio can auto-extract strings into a table via the Localization Tools plugin
