Feb 1, 2025February 2025 highlights the delivery of map-awareness and stability hardening for CleverRaven/Cataclysm-DDA. Core vehicle logic was updated to be map-aware with coordinated alignment across map and coordinates, culminating in the mapify merge. The map/coordinate system was expanded with Mapify visibility for character data and absolute coordinates for item_location and computer, plus talker-class coordinate updates. Ground protection from bashing was added, and a codebase refactor centralized shared logic to improve maintainability. Critical stability fixes included bounding box corrections, persistence of incomplete progress across runs, and robust explosion/environment handling (vehicles loading before explosions, proper item behavior, and correct map context). Review feedback was addressed to raise code quality and safety, and dangerous mine-field interactions were mitigated by removing road vehicles from mine fields.

Dec 1, 2024December 2024 for CleverRaven/Cataclysm-DDA focused on hardening type safety, stabilizing the test suite, and delivering targeted content improvements while improving code hygiene. Key efforts include typifying core headers and game structures across iuse, iuse_actor, game.h/.cpp, creature.h, monster.h, character.h, and npc.h, and extending type hints to core entities (character, NPC, explosion) and zones, complemented by cleanup that removes unused variables and parameters. These refactors reduce risk for future changes and enable faster, safer feature work. Major QA improvements include stabilizing vehicle_turret tests and expanding coverage, along with consistency fixes such as android pos → pos_bub and cellphone issues. User-facing content was enhanced with the Liam/Luo dialog addition, and testing tooling was strengthened with fake_messages. Overall, the month delivered measurable business value through stronger maintainability, more reliable CI, improved user experience, and faster feature delivery. Technologies/skills demonstrated include C++ type safety and refactoring at scale, test-driven development, code hygiene, and test tooling.
