XPilot project is a multi-player 2D client/server space game.
XPilot is a multi-player 2D space game. Some features are borrowed from classics like the Atari coin-ups Asteroids and Gravitar, and the home-computer games Thrust (Commodore 64) and Gravity Force (Commodore Amiga), but XPilot has many new aspects too.
Main features:
- True client/server based game; optimal speed for every player.
- Meta server with up to date information about servers hosting games around the world.
- A web of world-wide rating servers; compare your skills with pilots from all around the world, and climb the ladder of the world-wide rating list.
- Real physics; particles of explosions and sparks from your engines all affect you if youre hit by them. This makes it possible to kill someone by blowing them into a wall with engine thrust or shock waves from explosions.
- Specialized editors for editing ship-shapes and maps.
- Game objective and gameplay adjustable through a number of options, specified on the commandline, in special option files, or in the map files. Examples of modes of the game:
- classical dogfight; equipped with only your gun, you have to rely on your maneuvering and tactical skills
- team; fight together, steal other teamss treasures (involves flying around with a ball in a string, much like in Thrust) and blow up their targets (which are, no doubt, heavily guarded)
- all out nuclear war; chose carefully between more than twenty weapon and defense systems to stay alive and annihilate your enemies
- race; make it through the deadly course before your opponents
- Adjustable gravity; adjustable by putting special attractors or deflectors in the world, or by adjusting the global gravity in various ways.
- Cannons and personalized and vengeful robot fighters give you a hard time.
- Watch your energy, and remember to dock with a fuel station to refuel before its too late.
- Defend your home base, or terrorize and steal someone elses.
- Equip your ship with the 15+ defense and weapon systems: afterburners, cloaking devices, sensors, transporters, extra cannons, mines and bombs, rockets (smarts, torpedos and nuclear), ECM, laser, extra tanks, autopilot etc.
To start playing, you need to connect to a server by using a client program called xpilot. There are always servers running if you check with the meta server, but if you for some reason do not want to join them, youll have to start a server of your own (see man-page xpilots(6)).
Enhancements:
- Team cannons could kill teammates with laser pulses. Fixed.
- On the map Death Star one can destroy a large number of targets with one FNC. This results in packet buffer overflows and slow updates. To overcome this a smarter map update algorithm is implemented in the server and also map updates are now limited to max 2 KB per network packet.
- The default score font was reduced from 15 to 13.
- When the server sends map updates to the client these are now always acknowledged immediately by the client. This should help prevent stalls or lock-ups on maps where are a large number of targets or cannons can be destroyed. It should also reduce the number of very big server frame update packets.
- Robots no longer try to go after players who arent in playing mode.

TiWarriors project is an Asteroids clone with multiplayer support and incremental ship control.
Two things differ from the original: energy control and multiplayer mode.
Enhancements:
- added some config options like antialiasing and the option to switch to full screen or window mode.

This program places the required number of sodium ions around a system of electric charges, e.g., the atoms of a biological macromolecule (protein, DNA, protein/DNA complex).

The ions are placed in the nodes of a cubic grid, in which the electrostatic energy achieves the smallest values. The energy is re-computed after placement of each ion. A simple Coulombic formula is used for the energy:

Energy(R) = Sum(i_atoms,ions) Q_i / |R-R_i|

All the constants are dropped out from this formula, resulting in some weird energy units; that doesnt matter for the purpose of energy comparison. To speed the program up, the atoms of the macromolecule are re-located to the grid nodes, closest to their original locations.

The resulting error is believed to be minor, compared to that resulting from the one-by-one ions placement, or from using the simplified energy function. The coordinates of the placed ions are printed out in the PDB format for further usage.

It is recommended that the placed ions are equilibrated in a separate Monte Carlo or Molecular Dynamics simulation. Trivial modifications to the program should allow the placement of any combination of multivalent ions of different charges.

Dodgin Diamond 2 project is a little shoot-em-up arcade game.
The game is for one or two players.
It aims to be an "old school" arcade game with low resolution graphics, top-down scrolling action, energy based gameplay, and different weapons with several levels of power.
Main features:
- Top-down arcade game.
- One or two players.
- Energy based gameplay (up to ten hits).
- Music and sound where available.
- Three different weapons with five levels of power.
- Companion bot.
- Shield cells.
- 2 stages (with final boss).
- Full joystick support (one or two joysticks).

CodeInvaders Challenge project is a Java-based, real-time programming game based on the Eclipse platform.

CodeInvaders Challenge is a Java™-based, real-time programming game based on the Eclipse platform. It uses the Eclipse platform and a simple API that allows users unfamiliar with Java to easily compete while they learn the language.

CodeInvaders Challenge gives users the opportunity to pit their Java programming skills against other players in a battle of space conquest. Each player writes a Java class that represents and controls a spaceship. Each ship (class) is placed in a simulated battle along with ships from other players.

The game puts up to six spaceships together in a match and places each of them in a random location with the same amount of energy. The spaceship class allows each player to control his ships thrusters and weapons. The ship can move around to collect energy, attack opponents, and bring energy back to its home planet. Points are awarded for different actions, and the player with the most points wins.

When used in a tournament, CodeInvaders Challenge allows direct, real-time competition between teams. Each player can submit his intermediate solutions and test against the submitted ships from other players. This competition allows each player to learn from the strategies of other players and modify his ship appropriately. After the final submission from each player, the final winner can be found by running a tournament consisting of several rounds and eliminations.

M.U.L.E is a linux port of clone of old MULE for C64 & PC.

This is a Linux/SDL port of a MULE clone. For those unfamiliar, MULE is an early resource strategy game.

You play a colonist on the moon, you acquire territory, and decide how to use it, by either farming, mining ore, collecting solar energy or mining crystals.

You compete with 3 other players, most points at the end of a preset number of months wins.

Lincity project is an city simulation game for SVGALib/X/Win32/etc.

You are required to build and maintain a city. You must feed, house, provide jobs and goods for your residents.

You can build a sustainable economy with the help of renewable energy and recycling, or you can go for broke and build rockets to escape from a pollution ridden and resource starved planet, its up to you.

Due to the finite resources available in any one place, this is not a game that you can leave for long periods of time.
