Ataxx

[Ferdy]

Thanks! I understand Maybe fun to get something running.

I've put up the source-code at https://github.com/flok99/waxx if someone wants to add authentication or maybe run a server at home.

Ok I've implemented auth.
The first time you connect with an not-yet-known username, then that is automatically registered with the password you supply.

So, connect to server.ataxx.org port 28028 and send
user ...
pass ...
then regular UAI protocol commences.

On http://server.ataxx.org/ you can see the results of all that battling.

Is there a gui viewer for the output pgn?

This is an XBoard patch that makes it possible to use XBoard for Ataxx. It implements two things:

1) With argument -variant atx one enables 'Ataxx mode' where every enemy surrounding the to-square of a move will flip color.
2) With argument -dropMenu true, and if the pieceToCharTable only contains a single piece type (like -pieceToCharTable ".X.....o...."), a right-click on a square will not pop up a menu for selecting the piece you want to drop there, but drops it immediately. This allows you to play the 1-step moves as drops on the to-square by a simple right-click.

Code: Select all

The remaining configuring can be done by existing XBoard options (and can also be done by the engine through a 'setup' command):

xboard -variant atx -ncp -dropMenu true -pieceToCharTable ".X.....o...." -boardWidth 7 -boardHeight 7 -fen "X5o/7/7/7/7/7/o5X w" =men "X:mAmD@;o:mAmD@"

Of course you can also redefine the piece graphics to more suitable images through -pieceImageDirectory.

I had to replace "=men" by "-men" to get it to start.
Works almost complete: I could not do single-moves though.
Also "paste game" fails for ataxx games: http://server.ataxx.org/get-pgn.php?id= ... ed82fd9fcc

Is there a gui viewer for the output pgn?

Not yet afaik but people are working on it!

[hgm]

Well, there is Win/XBoard, but it would not read this crappy move format. And the FENs are also not compliant with FEN rules.

What is crappy about the move format? It's no more crappy than saying something like 1. e4 in chess instead of always saying 1. e2e4, isn't it?

And the FENs are also not compliant with FEN rules.

Well it is a different game?

[hgm]

It is crappy to describe something as a move with an implied side effect when the board mutation really is a simple drop. Standard notation for adding a piece to the board on e4 is X@e4. Not e3e4, d4e4 or whatever. And FENs are supposed to use upper case or white, no matter what game they are for, or they just aren't FENs.

There now is one!

If you go to http://server.ataxx.org/, then in the table at the bottom a column "view" was added. If you click that one, then you can view a game.

Not working at the moment. There is no move list.

Thanks.
Would be better if the pieces are more visible.
