Over three months, Alex Gandy developed interactive puzzle systems for the vgdc-ucsd/Mariposa repository using C# and Unity. He engineered a modular Door System with open, close, and lock mechanics, integrating BoxCollider2D triggers and external state control to support complex puzzle interactions. Alex enhanced maintainability by reorganizing scripts and exposing door states for editor inspection, improving debugging and testability. He also built a scalable Interactable Object System, introducing buttons, pressure plates, and switches with a centralized interaction flow. His work emphasized code organization, extensibility, and robust scripting, laying a solid foundation for designer-driven content and future gameplay features.
Month: 2025-03 — Delivered a scalable Interactable Object System to enable dynamic player interactions with the game world and enrich puzzle mechanics. Implemented Buttons, Pressure Plates, and Switches with a centralized SwitchInteraction flow, laying groundwork for a broader interactable object framework. This work enables environment-triggered changes (e.g., doors) and paves the way for designer-driven content iteration.

February 2025 monthly summary for vgdc-ucsd/Mariposa. Strengthened the door system with editor-friendly state exposure, improved observability, and expanded test coverage. Delivered a dedicated door test scene to validate interactions among door, lever, passcode, and player; ensured deterministic behavior through collider checks and Rigidbody2D simulation, with visual feedback via sprite color.

2025-01 monthly summary for vgdc-ucsd/Mariposa: Delivered a robust Door System feature enabling open/close via BoxCollider2D isTrigger, external ChangeState control, and lock/unlock mechanics. Reorganized codebase by moving the Door script to the Puzzles folder, improving maintainability and discoverability. The work enhances puzzle-driven interactions, enables external orchestration with other puzzles, and strengthens repository structure for future feature work. No major bugs fixed documented in this period.
