The BattleShip was developed using Java. It is an online game where one user has to sink the other user’s ships. The game uses Server-Client structure, each user has a map where he needs to allocate his ships and one map where he will choose where to shoot to try to hit his enemy’s ships. The one who hit all opponent’s ships first, wins the game. The ships allocation can be manually or automatic (random position) and there is also a chat implemented where one user can talk to his opponent. UPDATE: Battleship v2.0 has now single player mode. The user can play against the computer.

A bare bones RTS game framework. It has networking and replay support, and have some building blocks to build AI agents (discretized path finding in a continous world). Update (2025. Jun): javax.xml.bind.annotation.XmlAccessType was removed from JDKs later than 1.8. So use the project with JDKs from 1.6 to 1.8. Write in the forum if you're interested in running it on a more modern JDK. The demo program's entry point is Dom1Bootstrapper. You can download a runnable demo jar from the files. If your default JDK is higher than 1.8, it won't start on double click. Update (2014. May 9.): Detailed documentation is uploaded (i.e. my thesis). It examines the system from the user's perspective, but includes some internal details too. Of course it has some extra chapters here and there to conform to the format of a thesis. Check it out at the "Files" section (r221). There's also a corresponding src/bin/javadoc bundle there.
