About this project
What does Language Amend add?
Language Amend
Language Amend is a lightweight client-side mod that intelligently manages language fallbacks for Minecraft, ensuring a seamless multilingual experience by letting you define custom fallback chains for any language.
When using resource packs or mods that add translations in multiple languages, missing entries often default to English, breaking immersion. This mod allows you to automatically inject one or more fallback languages whenever a specific language code is detected—so every text remains readable and coherent, exactly as you intend.
✨ Features
- Smart Fallback: Automatically appends user‑defined fallback languages when a configured language code is present in the language list.
- Fully Configurable: Edit
config/lang_amend/lang_amend.jsonto create any number of mappings (e.g., maplzhto["zh_cn", "zh_tw"], oren_usto["en_pt"]). - Non-Intrusive: Works quietly behind the scenes without modifying game files or assets.
- Compatible: Plays nicely with other mods and resource packs.
🔧 How It Works
The mod hooks into Minecraft’s language loading system. If the current language list contains any key defined in your configuration, it appends the corresponding fallback languages—preserving the original order and avoiding duplicates. The result is a merged language list that respects your preferences.
📁 Configuration Example
{
"lzh": ["zh_cn", "zh_tw"],
"en_pt": ["en_us"]
}
Before: Use English when failed to find Literary Chinese translation

After: Use Chinese Simplfied when failed to find Literary Chinese translation
