Cameron contributed to the Cockatrice/Cockatrice repository by developing a card set prioritization and display enhancement feature. He introduced a set-type prioritization system that organizes card sets by Core and Expansion types, refactoring the existing sorting logic to support this new hierarchy. His work involved updating XML parsing routines and modifying core data structures in C++ to enable consistent prioritization throughout the user interface. This enhancement improved the clarity and scalability of card set organization, laying the foundation for future prioritization rules. Cameron’s approach demonstrated a solid grasp of C++ development, data structures, and software design within a focused project scope.
