Game of War

More game information can be found on the Bicycle Cards Website

TO WIN Be the first player to win all the cards

SET UP There are two players. Each player gets half the deck, faced down. Players are not allowed to look at their cards during game player.

GAME Play On each turn, each player lays down a card faced up at the same time. The player with the higher card takes both cards and places it on the bottom of their deck.

If the card value is the same, the game play enters War. Each player places three cards faced down, shouting "I declare war!", then opens the next card. The higher card wins. If the cards are still the same value, game play continues with War.

Card Values Ace is high. 2 is low. Goes in the following order:

2 3 4 5 6 7 8 9 J Q K A

AR Technology

Utilizing the JS-ArUco project, which ported over ArUco to Javascript, our team modified the existing code to place our own pictures on top. Also, since our card game needs to render two different images on different markers, we extended the library to include this functionality.

Using Three.js's Stereo API, we split the video canvas in two. The split helps us use the app on a phone and pair it with Google Cardboard.

You can now play the Game of War with replacable images!

Generating Markers

Before installing ArUco, you will need to install OpenCV. You can grab it from SourceForge or Brew.

Brew

brew tap homebrew/science
# Here you can check the open cv package
# brew info opencv
brew install opencv

You can grab ArUco on SourceForge and install with the following commands.

tar -zvf aruco.tgz # File will depend on your version
cd arcuo
mkdir build
cd build
cmake ..
make

Then go to the utils_hrm folder, and you can use the executables there.

cd utils_hrm
# Create a board with 5 rows, 2 columns, and output to image and yml config
./aruco_create_board 5:2 board.png board.yml
