Jass Challenge

Deployment

What is it?

The idea of this project is to run as a server whilst bots or humans play Jass (Schieber) against each other. It has two basic modes that clients can select to play.

Single Game Mode: Just one game that will start as soon as 4 players are connected to it. When one team reaches 2500 points it will be finished and every client of this session will be disconnected.

Tournament Mode: This mode has to be started over the Web Frontend of the server. Any number of bots can join this tournament. Since Schieber Jass is always played as a team, you have to connect two instances of every bot. This is validated with the name of the bot. When every bot has two instances connected, you can start the tournament over the UI and then every bot will be matched against all other bots at least once. Depending on your setting of rounds in the tournament (see Environment Section) it can be more than once.

Installation

You only need NodeJS to run this server. If you don't want to install NodeJS on your machine see: Docker Section

NodeJS

Installing node.js:

See http://nodejs.org/download/

Install node modules:

$ npm install

Start the server:

$ npm start

Docker Container

If you want to run the server in a docker container you can find a Dockerfile in this repo.

Build it and run it with:

docker build . -t jasschallenge # '.' is the directory of the repo
docker run -it --rm --name cs -p 3000:3000 jasschallenge

Environment Variables

There are some env variables you can set to alter the behaviour of the server.

TOURNAMENT_ROUNDS

A number that represents the amount of rounds a tournament will run. Each round all bots will play once against all other bots. Defaults to 1.

The Dockerfile already contains this environment variable and sets it to 5. So if you start the server with docker, default will be 5. To change this, simply edit the Dockerfile and build the image again like shown above.
TOURNAMENT_LOGGING

Boolean, if set to true, the server will store a json file for each game (Bot vs. Bot) with all the messages for parsing. These messages will be stored to the base directory of this repo.
TOURNAMENT_COUNTING

Boolean, if set to true, the server will count all modes without any multiplications (e.g. factor 3 for obenabe or undenufe will not be used).

Development

While developing you might want to run the server with a watch task. You can either use:

npm run start:watch

This task will start all the other tasks in watch mode. You can also start them directly. E.g.:

npm run build:js:frontend:watch

For more information check the package.json

To get more debug output there is a 'debug' task too:

<-- Start Broadcast: 
<-- Send Message: {"type":"BROADCAST_WINNER_TEAM","data":{"name":"Team 2","points":0,"currentRoundPoints":0}}
<-- Send Message: {"type":"REQUEST_PLAYER_NAME"}
<-- Received Message: {"type":"CHOOSE_PLAYER_NAME","data":"PlayerName"}
<-- Send Message: {"type":"REQUEST_SESSION_CHOICE","data":[]}
<-- Received Message: {"type":"CHOOSE_SESSION","data":{"sessionChoice":"AUTOJOIN"}}
<-- Start Broadcast: 
<-- Send Message: {"type":"BROADCAST_SESSION_JOINED","data":{"name":"PlayerName","id":0}}
End Broadcast -->

or if you just want to start the server without watching and debug output use:

$ npm start
