Worked on expanding material processing capabilities in the GregTech-Modern repository by implementing coral processing features using Java and mod development skills. Developed new macerator recipes that allow coral blocks and coral items to be crushed into calcite dust, enhancing early-to-mid game resource conversion and factory throughput. Introduced data-driven item tags for coral blocks and coral items, enabling consistent handling and supporting future recipe expansions. The technical approach focused on extensibility and maintainability, paving the way for broader material processing options within the mod. This work deepened the game’s resource mechanics and provided a foundation for ongoing feature development in game modding.
