CGOL 0.9.6

A whack Conway's Game of Life implementation.

CGOL ·

A Conway's Game of Life implementation using numpy and pygame.

Description

This project has no particular aim. It is a purely personal project and barely maintained.

It is a CLI based Conway's Game of Life implementation using numpy for fast calculations and pygame for an interactive simulation.

No Hashlife or Quicklife algorithm support (yet).

Rules of Conway's Game of Life

1. Any live cell with two or three live neighbors survives.
2. Any dead cell with three live neighbors becomes a live cell.
3. All other live cells die in the next generation. Similarly, all other dead cells stay dead.

Installing

Install using pip

pip install cgol

Manually install using CLI

git clone https://github.com/INeido/CGOL
pip install -e CGOL/.

Troubleshooting Installation

If you encounter any errors during the installation process, consider the following options:

If pip is not found you can try to access it using

python -m pip

or install it using

python -m ensurepip

You can attempt to install using pipx, a tool designed for running Python applications in isolated environments

pipx install cgol

If issues persist, create a virtual environment and install within it for a clean and isolated setup

python -m venv .venv
source .venv/bin/activate
pip install cgol

Usage

NOTE: If you installed using pipx you might have to run pipx ensurepath once or prepend pipx run to the example commands below.

Here are some examples.

Start a simulation with the default setting but with a custom seed.

cgol -se 42

Change grid size, cell size and fade color.

cgol -cf 130 20 0 -cs 8 -gh 90 -gw 160

Change the color to white on black without fade.

cgol -fa False -ca 255 255 255

Draw with the mouse to birth or kill cells.
