PROFILE

Ricardo Subtil

Over a two-month period, contributed to both the godotengine/godot and GameDevTecnico/cubos-demo repositories by developing core gameplay features and enhancing engine reliability. Built a wave-based cellular automata water simulation with terrain-aware diffusion, implemented health and perish mechanics, and introduced a per-player scoreboard and audio integration using C++ and plugin architecture. Addressed engine stability by refining Debug Adapter Protocol handling, including robust breakpoint management and non-ASCII content support through byte vector encoding. Fixed player collision and movement issues, improved restart workflows, and ensured clean import/export operations. Demonstrated skills in algorithm design, debugging, protocol implementation, and system programming throughout the work.

April 2025 monthly summary focused on hardening DAP communications in godotengine/godot by implementing non-ASCII content handling and encoding robustness. Replaced string payloads with a byte vector to ensure proper encoding and to prevent invalid DAP responses when content includes non-ASCII characters. The change improves reliability for international content and developer experience with external tooling. Commit reference: 094ded8009bb818e7fa5c311ff5cc83382ccf3ca.

March 2025 Monthly Summary: Strengthened engine reliability and expanded gameplay pipelines across two repositories. Key features include a wave-based cellular automata water simulation with terrain-aware diffusion, health and perish mechanics, comprehensive restart workflows, a per-player scoreboard, and audio playback integration. Major bugs fixed include recovery mode lock file cleanup during import/export and robust Debug Adapter Protocol (DAP) breakpoint management with source checksum refresh, plus a player collision fix for movement reliability. These changes improved runtime stability, debugging resilience, and gameplay flow, enabling cleaner exports, smoother restarts, richer simulation, and better player feedback. Technologies demonstrated span DAP protocol handling, cellular automata modeling, plugin architecture, health/destruction lifecycles, restart orchestration, scoreboard data structures, and audio integration.
