# Conway's Game of Life
I believe it was the fastest project I've ever done which took around 1.5 hours.
Infamous Conway's Game of Life implemented in C++ with SDL2.

## License
This project is licensed under the [GNU GPL-3.0](https://github.com/ErtyumPX/game-of-life/blob/main/LICENSE) license.
Feel free to use the source code. Referring to the repository would be very much appreciated.
## Setup
Project is currently compiled with `GNU G++ 13.2.1`.
The only third-party dependency is `SDL2`. Used version of SDL2 in project is `2.28.5`, should work as long as it is **SDL2** and not **SDL**.
For compiling and linking rules `GNU Make 4.4.1` was used. After downloading dependencies, make sure to change the include paths inside the Makefile.
```
# change the paths for '-I'
CC := g++
CFLAGS := -Wall -std=c++11 -I/usr/include/SDL2 # here
TEST_CFLAGS := -Wall -std=c++11 -Iinclude/SDL2 -Isrc/ # and here
LDFLAGS := -lSDL2 -lSDL2_image
...
```
After fulfilling dependencies, download or clone the project and use Makefile to easily compile:
```
> make all
> make run
```
Since SDL2 is a cross-platform media library, output should work on Windows, MacOS and Linux.
## Rules
The simulation goes in a 2D grid where each cell can be either dead or alive. The rules are as follows:
- Any live cell with fewer than two live neighbors dies, as if by underpopulation.
- Any live cell with two or three live neighbors lives on to the next generation.
- Any live cell with more than three live neighbors dies, as if by overpopulation.
- Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.

## General Structure
### Directory Structure and Files
- `src/` directory contains the source code
- `src/main.cpp` is the entry point of the program
- `src/game.hpp` contains the declarations of the methods
- `src/game_of_life.cpp` contains the implementation
- `stable/` directory contains the stable output
- `stable/game.life` is the executable
### How It Goes
Current version is not designed specifically to be used anywhere. Without any arguments, it will create a grid according to the `WIDTH`, `HEIGHT` and `CELL_SIZE` constants in `main.cpp`, randomly fill a grid and start the simulation.
The constant `FPS` is the frame rate of the simulation. It is set to 15 by default.
