A Pac-Man clone done as an example of the C++ game engine framework: GEngine.

PacMan.mp4

Building:

Prerequisites

• C++20 compatible compiler (GCC, Clang, MSVC).
• CMake ≥ 3.31.

Structure:

Folder Structure:

The project is divided between the core GEngine folder, and the PacMan game folder.

Thid party tools used by the engine can be found at GEngine/vendor/

Entry point:

Main program entry point can be found at PacMan/src/Bootstrap/main.cpp. Here, GEngine is initialized, and PacMan is loaded and run.

Contexts:

The game overall structure is divided in contexts. A context is an abstraction of an independent chunk of a game. The game has three main contexts:

• Shared context: contains essential parts used by all the different game contexts.
• Meta context: context that contains all the menus that the player finds before the main gameplay (main menu for example).
• Gameplay context: main gameplay of the game.

Third party

• Raylib (OS layer and rendering)
• ImGui (editor ui)
• Glm (math)
• Spdlog (logging)
• Tmxlite (tiled importing)
