Marauroa is Arianne's Multiplayer Online Engine Server, that you can use to build
you own online games using Marauroa as a Content Management system.

Extended Description
Marauroa is completely written in Java using a multithreaded server architecture
with a TCP oriented network protocol, a mySQL based persistence engine and a
flexible game system based on open systems totally expandible and modifiable
by developers and that is able to run scripts on Python for the game's rules.

Marauroa is based on a philosophy we call Action/Perception, on each turn a
perception is sent to clients explaining them what they percieve and clients
can ask server to do any action in their names using actions.
Marauroa is totally game agnostic and makes very little assumptions about what
are you trying to do, allowing a great freedom to create whatever type of game
you want.

You can find the latest version of Marauroa at:

Marauroa is a GPL project.

To actually compile Marauroa you will need:
- Java SDK 1.5
- Ant 1.6

In order to get it working with MySQL you will also need:
- MySQL Connector/J

  NOTE: Unfortunatelly, Marauroa uses some SQL features that make its code
  slightly incompatible with other DBMS. Join us and help to port SQL code
  to a real standard complaint DBMS.

- JUnit 4.4 in order to run test cases.
- Jython for Python support.

Make sure ant ( ) is installed.
Now just write:

  ant jar

Or for a complete package release write:


Version >= 3.0 does support Stendhal 0.76
Version >= 2.6 does support Stendhal 0.74
Version >= 2.5 does support Stendhal 0.68
Version >= 2.3 does support Stendhal 0.65.1
Version >= 2.2 does support Stendhal 0.65
Version >= 2.0 does support Stendhal 0.63
Version >= 0.90 && < 1.90 support Stendhal: a multiplayer Zelda like game using Java and Java2D
Version >= 0.90 support JMapacman: a multiplayer pacman game using Java and Java2D
Version >= 0.33 && < 0.90 support mapacman: a multiplayer pacman game using the Python rules.
Version >= 0.20 && < 0.33 support a simple Gladiators game using the Marauroa engine.

You need to grab a game package in order to be able to play it.

Ok, you have compiled Marauroa. Now what to do?

Well, if you have built a Marauroa server it is because you
want to play with the server either because you want to run your own
game server or because you are a developer wanting to develop your own game.
If you don't understand the above it is prone that you are looking for instead.

In order to test Marauroa with JUnit you need to setup a MySQL database:
  Database: marauroatest
  username: junittest 
  password: passwd
You can do that by doing:

  create database marauroatest;
  grant all on marauroatest.* to junittest@localhost identified by 'passwd';

Also please copy src/marauroa/test/server.ini to main project folder.

  cp src/marauroa/test/server.ini .
