pacman.zig is a faithful recreation of the classic Pacman arcade game implemented in the Zig programming language. It uses the Sokol cross-platform libraries for graphics, audio, and input handling, allowing it to run as a native desktop application or be compiled to WebAssembly for browser play. The game implements all original Pacman mechanics including Pacman movement, ghost AI with distinct behaviors for each ghost, dot and pill eating, bonus fruits, sound effects, score tracking, and level progression. The architecture follows a monolithic design with clear separation of concerns into game state management, game logic, rendering, audio, and input systems. Despite being contained primarily in a single source file, the code is well-organized with distinct sections for different subsystems. The implementation demonstrates attention to detail in replicating the original game's behavior and performance characteristics.
The LLM identified 3 files worth highlighting for reuse:
The ivec2 struct provides a clean, self-contained implementation of 2D vector operations including addition, subtraction, multiplication, equality checking, near equality with tolerance, and squared distance calculation. It has zero dependencies beyond basic types and could be extracted for use in any 2D game or graphics application with no modifications.
The Trigger struct and associated functions (start, startAfter, disable, now, since, between, afterOnce, after, before) implement a robust time-based triggering system for game events. It handles disabled states elegantly using a special tick value and provides precise timing control for game mechanics. While it depends on the global game tick, the core logic is easily adaptable to other timing systems.
The Dir enum with Right, Down, Left, Up values, along with reverseDir() and dirToVec() functions, provides a clean encapsulation of directional logic for grid-based movement. This component is completely self-contained with zero dependencies and could be trivially extracted for use in any grid-based game or application.
