Harry Xi contributed to the AllayMC/Allay repository by engineering core gameplay systems and server-side features using Java and related backend technologies. Over four months, he developed foundational mechanics such as a Bow and Arrow system with physics-based trajectory and damage logic, a beds system with placement and interaction rules, and robust trapdoor functionality. He enhanced server usability through improved command-line tools, internationalization support, and error handling, while also implementing a world structure API for NBT-based save/load operations. His work demonstrated depth in backend development, game logic, and maintainability, addressing both user experience and developer onboarding through clear documentation and targeted bug fixes.
August 2025 monthly summary for Allay: Delivered foundational gameplay enhancements and a critical bug fix to improve gameplay fidelity and future feature readiness. Key features delivered include a Bow and Arrow System establishing baseline arrow behavior, physics, damage, enchantments, and item integration (with trajectory calculations), and Beds System implementation covering placement, interaction, breaking logic, translation updates, and related command changes. Major bugs fixed include Ender Pearl Damage Fix to ensure Ender Pearls do not damage Blazes by correcting projectile damage calculations. Impact: enhanced gameplay realism and stability, improved Creative-mode behavior, and a solid base for further combat and base-building features. Technologies/skills demonstrated include Java game systems engineering, projectile physics modeling, damage calculation, internationalization/translation keys, command architecture, and targeted refactoring.
