If you just want to use the programs all you need will be the client and server, if you wish to modify, contribute, or compile all three archives will be needed.
Major Update
Some of the client code has been corrrected. The server is now in Python for a lower resource consumption, the original Java version is available by email though it will not be maintained by me. Modules (bots) can now be reloaded by the admin without restarting the server they also have a lot more functionality.
New features include: Logging.
A few minor features like back logging (using recall to see the last few lines of a room) and using the arrow keys to navigate through posted lines in the client.
New features include: Modules.
Dice rolling is now performed by a module.
New features include: In chat character editor. Module and bot coding. More detailed instructions and documentation.
New features include: Character sheet viewer.
New features include: inline help for the client, improved die roller and dialog in the client, cross client drawing canvas, bots which respond to keywords, tightened code to keep memory usage to a minimum. Also updated the alias list for open aliases enabled.
This game will soon be hosted on the network, the chat will still be considered a demo, what better way to demonstrate it's abilities than to host an actual game on it? Once the site for the game is finished this chat will link directly to that one, though you will hopefully be able to chat with gamers about how well they like it.
