The Dink Network

I've now tweaked dinkvar.c and freedink.c in the freedink source code
to pull data from a remote source, and written a trivial D-MOD to test
it. The results are at:

https://github.com/barrycarter/bcapps/tree/master/DINK/bctest
https://github.com/barrycarter/bcapps/blob/master/DINK/bc-make-screen.pl

but you unfortunately can't just download this and play it.

I made source code changes to "freedink-1.08.20090120" (the only
version that compiles for me), so you may need to make different
changes (I believe a lot of the functionality of freedink.c and
dinkvar.c has moved to other C files).

The main change I made is adding these lines to dinkvar.c:

< save_game(0);
< char cmd[200];
< sprintf(cmd,"/home/barrycarter/BCGIT/DINK/bc-make-screen.pl %d %s",num,path\
s_dmodfile(path));
< system(cmd);

[as the comments (which I don't quote above) point out, hardcoding my
home directory is not very portable]

bc-make-screen.pl is the external program that does most of the work
by reading the current state of the game (from save0.dat), creating a
single screen map.dat file, and writing story/DYNAMIC.c (which is
called per the created map.dat file).

Because the created map.dat file is only one screen, I changed:

> fseek(f, holdme, SEEK_SET);

to

< fseek(f, 0, SEEK_SET);

The changes I made to freedink.c are adding:

*pmap=34;

after every instance of:

draw_map_game();

This keeps Dink on the "same" screen, but the global variables &x, &y,
and &z (initialized in story/MAIN.C) keep track of where Dink "really"
is. This allows for an infinite number of screens.

Currently, the D-MOD just has Dink announcing his x, y, and z
coordinates as he walks around a perfectly barren world. You currently
can't change the &z coordinate, but i plan to bind the Z key for this
later.

I would appreciate thoughts, suggestions, etc.
