There has been a lot of discussion in the Kdegames mailing list regarding the porting of the games from deprecated libraries like KGameRenderer and KGameTheme to new rendering methods and Graphics stack. This is a very good opportunity for new contributors to start contributing to Kdegames. Although some of the ports might be a bit difficult but there are easy ones too once the code of a game specially the rendering portion of the code is understood. The port table is available here http://community.kde.org/KDE_Games/Porting. A basic understanding of Qt/C++ would be required, but the junior jobs should get one up to speed for tackling the ports.
For people who want to start contributing to Kdegames , it is advisable to go through the following steps in order
1. Subscribe to the Kde-games-devel mailing list (https://mail.kde.org/mailman/listinfo/kde-games-devel) . For those who do not know what it is, a mailing list is basically a kind of a forum where people post their queries or doubts or submit their patches. When they do that, all the people who are subscribed to this mailing list get notified by mail so that they can entertain their queries or the maintainers of the games can review the submitted patches.
2. Try to hang out in the official IRC channel (#kde-games on freenode) . You can have direct conversations with people from Kdegames here.
3. Post your willingness to contribute in the mailing list. It is more recommended than posting in the irc channel .One thing that has to be followed after posting in the mailing list is patience. People are busy and are from a lot of different time zones. They reply according to their convenience which has to be respected.
After following these steps , you should get a junior job which would surely help you get familiar with the source and in general to contribution if its your first time contributing.
Kdegames is a small group of developers and contributors and despite that they have done an awesome job. Although I haven’t been in Kdegames for very long but I really like this group and I would definitely want more people contributing to Kdegames which would help it become even better than it already is.
