This is a simple bot for http://vindinium.org/ implemented in SWI-Prolog.
This works with SWI-Prolog 7 or later, with HTTP support installed. For most Linux distributions, this means it is easiest to build SWI-Prolog from source. See http://www.swi-prolog.org/build/ for details.
The main program is contained in a single file, vindinium.pl. Currently, there is a single, "random" bot implemented in randbot.pl. The user key is read from a plain text file containing nothing but the key, called by default userkey (you can change this: see the first line of vindinium.pl).
To run the bot, start SWI-Prolog in the directory with the three files, and load the program:
$ swipl

For help, use ?- help(Topic). or ?- apropos(Word).
?- [vindinium].
true.
At that point, you can either fight at the arena:
?- fight.
... or train:
?- train([turns=50]).
You can leave the list of options empty, or supply number of turns and a map (see the Vindinium documentation).
The bot implemented in randbot.pl just walks around without direction. He might take possession of a mine or have a drink, if he happens to see one right next to him. He completely ignores other heroes.
If everything goes well, both fight/0 and train/1 should succeed once the game has finished. Failure most probably indicates an error (a bug in the program) that I haven't noticed yet.
After making any changes to your code, use make/0 to re-load everything:
?- make.
% Updating index for library /home/boris/lib/swipl-7.1.23/library/
% /home/boris/code/vindinium/greedy compiled into bot 0.01 sec, 27 clauses
true.
Enjoy!
