A piksel-based implementation of the popular Game of Life created by J.H.Conway.

This implementation uses a simple toroidal grid, meaning that the bottom and top edges are considered adjacent, and the same goes for the left and right edges.

• A C++ compiler supporting the C++11 standard
• CMake (version 3.12 or greater)

After cloning this repository, add piksel by typing:

git clone --recursive https://github.com/bernhardfritz/piksel.git

You can then compile the main executable using CMake:

mkdir build
cd build
cmake ..
make

If you want to modify the existing code, you might be interested in using the DEBUG(msg) macro (defined in src/debug.hpp), which allows to print the message msg on the terminal. You can used it in a cout-like style, e.g.,

int val = 0;
std::string s("hello")
DEBUG("Initialized 'val' to " << val << " and 's' to " << s);

To see the messages, you need to enable the "DEBUG" option as in cmake .. -DDEBUG=ON or using CMake's GUI.

You can run the app using any of the following commands:

./game_of_life
./game_of_life size
./game_of_life width height

The second one creates a squared grid whose side is of given size, while the last form allows to specify the grid dimensions individually.

Once the app is running, you should see a Glider in the middle of the grid. You can click anywhere on the grid to create or destroy a cell. Use the space bar to start/pause the game, and the "+" and "-" keys on the numpad to increase/decrease the speed of the game.

Enjoy!
