During their work on the SymmetricDevs/Supersymmetry repository, Kouko implemented an Iron Armor Recycling System designed to recycle iron armor into core resources, addressing resource duplication and improving in-game economy stability. They refactored the crafting logic to utilize a centralized RecyclingHelper, specifically leveraging Groovy’s replaceShaped method for greater consistency and maintainability. By consolidating resource management logic, Kouko enhanced testability and reduced technical debt, enabling smoother future development. Their technical approach focused on game development and modding best practices, resulting in a more reliable resource flow and a clearer maintenance path for upcoming features within the project’s codebase.
