Developed a comprehensive zh_CN translation file from scratch using JSON, ensuring completeness and accuracy while refining existing translations for clarity and consistency. Reorganized mod assets to align with packaging standards, moving files to the correct directory structure for easier maintenance. Collaborated through co-authored commits to facilitate quality review and maintainability. Applied skills in localization, translation, and modding to streamline the mod’s language support, ultimately simplifying future updates and improving usability for the target player community.
