This is a slightly modified version of Sebastian original code-elevator, we have changed :

• A script to run the server (./run.sh)
• The admin login/password is hardcoded to admin/admin
• The default number of potential passenger is bumped from 0 to 3

The goal of the game is to implement an elevator engine. Participants have to subscribe with a login, an email (in order to display a linked gravatar) and a server url. Then HTTP GET requests will be send to this server :

• /call?atFloor=[0-5]&to=[UP|DOWN]
• /go?floorToGo=[0-5]
• /userHasEntered
• /userHasExited
• /reset?cause=information+message

• /nextCommand : body of the request must contains NOTHING, UP, DOWN, OPEN or CLOSE

Here is what you need to build and run a code elevator session :

• JDK 1.7
• maven 3.x

$ git clone https://github.com/jeanlaurent/code-elevator.git
$ cd code-elevator
$ ./run.sh

If you can't run shell script on your machine, just type in :

$ mvn clean install
$ mvn --file elevator-server/pom.xml jetty:run

Go to http://localhost:8080, subscribe to a session and start implementing your elevator server.

If you want to increase the number of people at any given time, go to http://localhost:8080/#/administration, log in with user admin and password admin, and adjust (add or remove) the number of people taking the elevator. If you put 0 person, no one will call the elevator.

Don't want to install Java nor fill up your hard drive with jar files you can try Sebastian's online server
