Simple Pacman clone written in C99.

pacman.c

A Pacman clone written in C99 with minimal dependencies for Windows, macOS, Linux and WASM.

WASM version

For implementation details see comments in the pacman.c source file (I've tried to structure the source code so that it can be read from top to bottom).

Clone, Build and Run (Linux, macOS, Windows)

On the command line:

git clone https://github.com/floooh/pacman.c
cd pacman.c
mkdir build
cd build
cmake ..
cmake --build .

NOTE: on Linux you'll need to install the OpenGL, X11 and ALSA development packages (e.g. mesa-common-dev, libx11-dev and libasound2-dev).

On Mac and Linux this will create an executable called 'pacman' in the build directory:

./pacman

On Windows, the executable is in a subdirectory:

Debug/pacman.exe

Build and Run WASM/HTML version via Emscripten

NOTE: You'll run into various problems running the Emscripten SDK tools on Windows, might be better to run this stuff in WSL.

Setup the emscripten SDK as described here:

https://emscripten.org/docs/getting_started/downloads.html#installation-instructions

Don't forget to run source ./emsdk_env.sh after activating the SDK.

And then in the pacman.c directory:

mkdir build
cd build
emcmake cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=MinSizeRel ..
cmake --build .

To run the compilation result in the system web browser:

> emrun pacman.html

IDE Support

On Windows, cmake will automatically create a Visual Studio solution file which can be opened with the start command:

cd build
cmake ..
start pacman.sln

On macOS, the cmake Xcode generator can be used to create an Xcode project which can be opened with the open command:

cd build
cmake -GXcode ..
open pacman.xcodeproj

On all platforms with Visual Studio Code and the Microsoft C/C++ and CMake Tools extensions, simply open VSCode in the root directory of the project. The CMake Tools extension will detect the CMakeLists.txt file and take over from there:

cd pacman.c
code .
