Dependencies

This program uses libpng.

To install on Debian based systems:

sudo apt-get install libpng-dev

Quick start

Clone this repo and then do:

cd knights
make
./knights Knight-Knight 256 output.png

The first parameter defines the opponents.

Possible opponents are:

Knight, Dromedary, Alfil, Antilope, Dabbaba, Wazir, Zebra, Ferz, Manis, Sipius, Xoch.

The maximum opponents is currently 20.

The second parameter is the size of the output image.

256 = 256 x 256 pixels.

Should be an even number not greater than 2048.

./knights Knight-Antilope 1024 out.png

./knights Knight-Dabbaba-Wazir-Wazir 1024 out.png

This one is different from the image shown in the video. I think they did something wrong.

./knights Knight-Zebra 1024 out.png

./knights Wazir-Ferz-Wazir-Ferz 1024 out.png
