Developed and delivered the Duffel Bag Wear Detection feature for player characters in the Qbox-project/qbx_core repository, focusing on enhancing character customization and item recognition. The solution involved creating model-specific index tables for duffel bags across male and female character models and implementing a torso-component verification function to accurately identify cosmetic items. This work leveraged Lua scripting and game development skills, emphasizing module-level feature development and data modeling for character cosmetics. The feature improved workflows for model-aware item indexing and provided clear version-control traceability, laying a foundation for future enhancements in character customization without addressing major bug fixes during the period.
