How do I register language files in Foundry VTT?

Language files must be declared in the 'languages' array within your module.json or system.json manifest file, specifying the ISO language code, display name, and file path.

How do I handle plurals in Foundry VTT localization?

Foundry does not have a native pluralization engine. The best practice is to define separate keys (e.g., KeyOne and KeyMany) and use logic to select the appropriate key based on count.

What is the difference between localize() and format()?

game.i18n.localize() is used for simple static string lookups, while game.i18n.format() is used when you need to inject variables into a string using placeholders like {name}.

Why should I namespace my localization keys?

Namespacing (e.g., MYMODULE.Title) prevents conflicts with other modules or the Foundry core software, ensuring your translations are loaded and displayed correctly.

Can I use localization directly in Handlebars templates?

Yes, you can use the {{localize 'KEY'}} helper for simple strings or {{localize 'KEY' var=value}} for strings requiring data interpolation.

ゲーム開発

Streamlines the implementation of internationalization and localization for Foundry VTT modules and systems using standardized API patterns.

The Foundry VTT Localization skill provides expert guidance for implementing internationalization (i18n) within the Foundry Virtual Tabletop ecosystem. It assists developers in creating structured JSON language files, utilizing the game.i18n JavaScript API for string lookups and interpolation, and applying Handlebars helpers for template-based localization. By following these established patterns, developers can ensure their modules are translation-ready, avoid common pitfalls like hardcoded strings, and maintain consistent naming conventions across complex system architectures.
