Review Of 2010

2010 marks the Arianne Project's 10th birthday, so what better year to review progress of this open source project?

Arianne comprises a multiplayer online games framework and engine to develop turn based and real time games, called Marauroa, and the various games which use it. Of those games Stendhal, a MORPG, is the most popular and actively developed.

Project of the Month

Arianne was chosen as SourceForge project of the month in March. We were on the front page of http://sourceforge.net throughout March and we have our own permanent feature page at http://sourceforge.net/blog/potm-201003/ - you check out an interview with the project leaders there. We saw downloads double over this time, and saw increased interest in our development too.

Busy Project

Arianne has ranked highly on activity over the year on SourceForge. For some weeks we've been ranked as highly as 2nd place, and are often in the top 25 each week. In 2010 we entered the top 50 all time activity ranks, too.

For another year we welcomed new developers to the project, this year storyteller, Laguz, Bluelads4 and omero, all of whom started as Stendhal players.

In 2010, we announced 13 Stendhal releases and 7 Marauroa releases (with some minor bug fix releases too).

Stendhal Milestones in 2010

Early in the year we introduced a NPC facilitating player-to-player trading, dynamically produced mazes and informative shop signs displaying item information.

We also launched a sophisticated new sound system for music and sound effects, with a lot of new audio added at the same time. The system can supports localised sound, fading, sound on events, and management of sound groups. To simplify the user interface we added a mode where single mouse clicking will walk, attack, look, harvest, loot, or perform some other action based on what is being clicked on. The mouse cursor shows what the action would be. The whole client got a new look and feel, with the GUI rewritten entirely in swing. This enabled us to move floating panels off the gameplay area and onto new, fixed side panels to the client.

We took our first steps towards a magic system, by introducing fire, ice, dark and light attack and defense types for combat for creatures and players. New AI profiles for creatures.

Trade GUI. Find bugs

fun stuff for players: wizards circle quest, rat raids, mazes, kalavan orb, lots of new quests added throughout the year, semos mine town revival with new game, easter bunny, santa

TODO: add the rest

Marauroa Milestones in 2010

Marauroa is the engine of the Arianne project. It has two main functions: Manage the communication between the servers and the clients. And store the player progress to a persistent database. Therefore this section will be very technical.

The most visible change with regard to the database was adding support for the installationless H2 database at the beginning of 2010. H2 requires no download, installation or configuration which is a huge improvement on MySQL. Under the hood games can now update the database structure automatically on first server start after an update.

You may have noticed that Clone Wars in Stendhal on 2010-02-20. As a result, Marauroa now supports configrable limits on account and character creation and number of parallel connections per IP address. This is just a precaution, Marauroa did handle the huge amount of parallel characters very well.

In preparation for the POTM, we overhauled our documentation, integrating and improving JavaDoc, Wiki and Website. So that new developers can easily start using Marauroa. Last but not least, RPEvents now supports RPSlots, which allowed the Shop signs in Stendhal.

The summer was focused on improving performance: Database access is now completely handled asynchronously, which greatly reduced lag spikes. Marauroa used to have a huge lock on PlayerEntryContainer which prevented processing of all message during an active turn. However, only placing players into the world and removing them needs to be synchronized. So all other messages are now processed in parallel, which speeds up logins noticeable.

For the developers, we added support of a new datatype for maps. This required a change to the Marauroa protocol and while we worked on it, we added support for multiple protocol versions, so a newer server can now talk to older clients and via versa.

We concluded the year with adding support for a test server environment which shares some database table with the main server. So players are now able to test the upcoming releases with their own characters. Marauroa is the first sub project that switched from the development coordination tool CVS to git.

All over the year we fixed minor bugs and improved stability.

website?

arianne.sf.net and stendhalgame.org both saw a lot of changes. also stendhalgame.org was registered

unsorted

Stendhal webstart and updates are now signed with a verified java code certificate carrying the name of the project! We were happy to discover free of charge certificates for Open Source Projects from http://certum.eu/certum/cert,offer_java_code_signing.xml and we had the opportunity to change our update package so we used the new certificate at t

new test server ?

graph ideas - we have some of these saved already

stats.. ranking, download, findbugs, numbers, cvs activity, tracker age

e.g.

although hang on those dates don't make sense!

community involvement - new developers, events like hunt for the lost cat, spring tournament, quizzes

Outlook

early 2011? quest log, achievements, groups

stendhal 1.0 - stable at 0.9* for some time before

containers, magic ?
