Free role playing game software for linux

Role Playing Tools extends the pen and paper role playing tabletop to the computer by providing a die rolling tool with a full expression language including Javascript functions, tabbed rolling bars, quick summation features, and the ability to save and restore sessions. There is also a client and server map sharing tool. Both are intended to be simple and powerful and enhance the game, not distract from it.

We found that we wanted to augment our pen-and-paper roleplaying (primarily 3.5ed D&D) with computer aids.

These tools extend and augment our traditional playing style. They are not a role playing game by themselves, nor are they meant to replace everything at the D&D table.

DiceToolis a simple but powerful expression parser that has built in functions for random number generation and can be further extended by JavaScript to do all sorts of calculations.
MapToolis an elegant graphical tool to share maps (images) and map data (drawings, markers, grid placement) in a client/server fashion between multiple players.
TokenToolis an accessory to MapTool. Drag any image onto the workspace and use the mouse to move and zoom the image in the reticle. Then drag from the preview pane directly onto MapTool -- or File->Save to save a png file.

Lost Labyrinth is a so-called "roguelike" RPG playing computer game.
Main features:
- relatively short gameplay (about 10-20 minutes)
- very high replayability; nearly everything in the game is randomly generated
- Sketelona lot of options during the character generation; each character type requires another strategy to survive
- game focus on exploration; killing monsters does not give an experience bonus (but makes fun nonetheless)
- Multiplayer games on the same machine (up to 3 players with keyboard, mouse and joystick)
- "Zelda"-like graphics, sound and animation; smooth scrolling of game screen
- FreeWare
Enhancements:
- You can pick up items with the mouse (the pointer changes when you can interact with something).
- You can scroll spells with the mouse (up/down buttons).
- A text entry bug (could enter only one character since the new compiler) has been fixed.
- German special letters and spells have been fixed.
- An issue where the trader left you one field to the right (in the wall sometimes) has been fixed.
- The borders of the credits and high score screens have been fixed.
- The language of the help screen has been fixed.
- A merchant will wait a while before buying/selling is possible.

Online Cardgame System project is a client-server system for playing card games over the net.
OCS is a client-server cardgame system, similar to those found at Yahoo! Games and elsewhere. The server is portable and has been tested under Linux, Win32, and several unix systems. We currently have Win32 and Java clients available, and a Qt client for Linux is in development.
Games are implemented as plugin modules, so new games can be added without recompiling the server. In addition, the client is written to be unaware of the mechanics of gameplay, so it can theoretically play any games the server supports without having to know how to play them specifically.
We currently have Euchre and Spades implemented, with bot support for both games, meaning you dont need a full 4 people to play a game. We plan on implementing more games in the future.
On a side note, development of this project tends to wax and wane with our motivation and amount of schoolwork.
Enhancements:
- Massive restructure of code into more object orientated patterns
- Added daemon capability to server
- Got rid of checksumming in the protocol since TCP/IP does it internally
- Padded STRINGS in the protocol on DWORD boundaries
- Added support for loadable account managers
- Removed crypting of the password by ocsd (account managers may do it)
- Added ODBC (for windows) and mySQL (for unix) account managers (database connectivity!!)
- Modified packet classes to throw exceptions instead of returning true-false
- Created packet manager classes to queue client packets, reduces total send calls
- Implemented bots when there arent enough people to play games
- Added new command line processing capabilities as well as configuration file support
- Fixed bug that allowed a person to overwrite an account when creating that same account
- Win32 - Made server link with DLL runtime library to reduce executable size and ease DLL dependencies
- Updated messages to be sent in HTML since the main clients support it
- Created Java client which can be run as an application or as an applet
- After a client is booted from a game, they cannot join the game again until they receive an invitation
- Fixed libtidy bug which caused it to erroneously format HTML
- Euchre supports intelligent bots
- Spades supports moronic bots (the AI is horrible but allows for gameplay)
- Fixed Spades textual problem when a round was over.
- Fixed Spades score calculation that resulted in no loss of points
- Win32 client now supports HTML (IE4+ required)
- Win32 client can now join games by right-clicking on an empty game slot in the game view.
- Fixed major bug in Win32 client that would cause it to crash when sending private messages
- Win32 client can now use /msg to send private messages

Scroll Rack is a virtual tabletop on which you can play card games against other people over a network.
Scroll Rack was designed to simulate the Magic: The Gathering (R) game, but it can be expanded to simulate other games.
It supports two-player peer-to-peer mode, and client/server mode for multi-player games and tournaments.
Main features:
- Open source.
- Support planned for Linux, Mac, and Windows.
- Can download card images from www.wizards.com and display them on the virtual tabletop.
- Clients can connect directly (peer-to-peer) or through a server run by a third party.
- Peer-to-peer games use encryption to prevent players from seeing cards they arent allowed to see.
- Peer-to-peer games use Jabber so both players can be behind firewalls.
- Client/server games support any number of players and watchers.
- Supports Living Wish (move card from sideboard to hand).
- Supports Battle of Wits (very large decks).
Enhancements:
- Add Deck Editor.
- Download card images from magiccards.info instead of wizards.com. Higher quality images.
- Download Oracle spoiler file from a Scroll Rack dedicated site instead of gatherer.wizards.com. Faster, more reliable download, with more data.
- Rearrange files in .scrollrack.cache.
- Add Save Log menu item.
- When starting a game with a sideboarded deck, show note in New Game dialog.

Sloth Online RPG is aJava Online RPG with Real-Time Action and rich 2D graphics.

Sloth Online RPG is a work in progress that will provide a fully graphical online role playing game engine. SlothORPG is coded in Java and is currently in a near playable state featuring several classes with over a thousand lines of code.

My main intentions with this project are to provide a free, fully functional, ever expanding Role Playing Engine (both client and server side) for the end user who would be playing the game. Developers would also be able to use the project as a resource on certain aspects of Java Game Programming.

Server side the project implements the NIO Networking library to create a smoother, stronger tcp/ip core. I found UDP and TCP w/ the old IO library to be unreliable and sluggish respectively. The way in which the server is structured has proven to be strong thus far.

The client side of the code features the Graphics2D Java library to provide near perfect animation without requiring a rendering device such as OpenGL or DirectX.

To summarize my entire intent for this project I basically wanted to provide an Online RPG that is functional on almost any OS that has Java installed and can run just as smooth on low end machines while still being able to feature rich 2-D graphics. The source code is clean and neat as well as commented and organized.

It is easy to read and understand for someone who has some knowledge of Java. As I write this, the project is coming along nicely and some pre-alpha local network testing has proven this. I plan to continue with this project and in the future include database integration and more of a developer-side interface.

A quick rundown of what this project includes so far: Character Creation, Smooth character animation, and fully supported tcp/ip gameplay. Chatting is also implemented.

JFlag project is a RTS-like game with multiple play modes.
JFlag is an RTS-like game with multiple play modes (capture the flag, last man standing, etc.).
Main features:
- Network game, up to 9 players
- Gameplay based on XML files, so *everything* is easily customizable
- Random map generation
- And many more..

IRE - The IT-HE RPG Engine is a 2d role-playing game engine similar to that used by Ultima 6.

IRE is an attempt to create a cross-platform computer role-playing-game engine similar to Ultima 6 but with more modern features such as rooftops, special effects and Ogg-vorbis music.

The engine runs in 640x480 at 15 bpp upwards. It is controlled by scripts which are compiled into interpreted code for extra portability.
