Language Generation

Language files can be generated for a mod by subclassing LanguageProvider and implementing #addTranslations. Each LanguageProvider subclass created represents a separate locale (en_us represents American English, es_es represents Spanish, etc.). After implementation, the provider must be added to the DataGenerator.

// On the MOD event bus
@SubscribeEvent
public void gatherData(GatherDataEvent event) {
    event.getGenerator().addProvider(
        // Tell generator to run only when client assets are generating
        event.includeClient(),
        // Localizations for American English
        output -> new MyLanguageProvider(output, MOD_ID, "en_us")
    );
}

LanguageProvider

Each language provider is simple a map of strings where each translation key is mapped to a localized name. A translation key mapping can be added using #add. Additionally, there are methods which use the translation key of a Block, Item, ItemStack, Enchantment, MobEffect, and EntityType.

// In LanguageProvider#addTranslations
this.addBlock(EXAMPLE_BLOCK, "Example Block");
this.add("object.examplemod.example_object", "Example Object");

// Encdoded as 'Example with a d\u00EDacritic'
this.addItem("example.diacritic", "Example with a díacritic");
