Seamines and landmines share storage. Sea and bridge span sectors can
hold only sea mines, other sector types only landmines. Sector type
checks were missing or incorrect in several places:
* Seamines under bridge spans were mistaken for landmines in several
places:
- ground combat mine defense bonus, in get_mine_dsupport() and
stre(),
- land units retreating from bombs, in retreat_land1(),
- non-land unit ground movement (commands explore, move, transport,
and INTERDICT_ATT of military), in check_lmines(),
Fix them to check the sector type with new SCT_MINES_ARE_SEAMINES(),
SCT_LANDMINES().
* plane_sweep() mistook landmines for seamines in harbors. Bug could
not bite, because it's only called for sea sectors. Drop the bogus
check for harbor.
* Collapsing a bridge tower magically converted landmines into
seamines. Make knockdown() clear landmines.
Also use SCT_MINES_ARE_SEAMINES() and SCT_LANDMINES() in mine(),
landmine(), lnd_sweep() and lnd_check_mines(). No functional change
there.
Keep checking only for sea in pln_mine(), plane_sweep(),
retreat_ship1(), shp_sweep() and shp_check_one_mines(). This means
seamines continue not to work under bridges. Making them work there
is tempting, but as long as finding seamines clobbers the sector
designation in the bmap, it's better to have them in sea sectors only.
Historical notes:
Mines started out simple enough: you could mine sea and bridge spans,
and ships hit and swept mines in foreign sectors.
Chainsaw 2 introduced aerial mining and sweeping. Unlike ships,
planes could not mine bridge spans. plane_sweep() could sweep
harbors, which was wrong, but it was never called there, so the bug
could not bite.
Chainsaw 3 introduced landmines. The idea was to permit only seamines
in some sector types, and only landmines in the others, so they can
share storage. To figure out whether a sector has a particular kind
of mines, you need to check the sector type. Such checks already
existed in mine, drop and sweep, and they were kept unchanged. The
new lmine command also got the check. Everything else did not.
Ground movement and combat could hit and sweep seamines in bridge
spans. Ships could hit and sweep landmines in harbors.
Empire 2 fixed land unit movement (march, INTERDICT_ATT) not to
mistake seamines for landmines on bridge spans. It fixed ships not to
mistake landmines for seamines. The fix also neutered seamines under
bridge spans: ships could neither hit nor sweep them anymore. Both
fixes missed retreat.

Welcome to Empire 4, code-named Wolfpack.
Empire is a multi-player, client/server Internet based war game.

This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License (in file
`COPYING'), or (at your option) any later version.
See file `CREDITS' for a list of contributors.
Directory `doc' has additional information. File `doc/README'
describes the files there and what they talk about.
To build the server and set up a game, follow the steps below.
(1) Unpacking the source tree
If you downloaded a tarball, unpack it.
If you cloned a git repository, run bootstrap. This requires
recent versions of Autoconf and Automake to be installed.
(2) Building a server
Prerequisites: IEEE Std 1003.1-2001 (POSIX.1-2001), GNU make, a
curses library, Perl, and either nroff or GNU troff (`groff').
See file `INSTALL' for detailed compilation and installation
instructions. Quick guide for the impatient: run configure; make;
make install. The last step is optional; everything runs fine
right from the build tree.
If make fails without doing anything, you're probably not using
GNU make. Some systems have it installed as `gmake'.
Solaris supports POSIX.1-2001, but you need to set up your
environment for that. Try passing
SHELL=/usr/xpg4/bin/sh PATH=/usr/xpg6/bin:/usr/xpg4/bin:$PATH
to make. See standards(5) for details.
(3) Creating a game
* Create a configuration for your game. make install installs one
in $prefix/etc/empire/econfig ($prefix is /usr/local unless you
chose something else with configure). You can use pconfig to
create another one.
* Edit your configuration file. See doc/econfig for more
information.
Unless you put your configuration file in the default location
(where make install installs it), you have to use -e with all
programs to make them use your configuration.
* Run files to set up your data directory.
* Run fairland to create a world. For a sample world, try
`fairland 10 30'. This creates file ./newcap_script, which will
be used below. You can edit it to change country names and
passwords.
Check out fairland's manual page for more information.
* Start the server. For development, you want to run it with -d
in a debugger, see doc/debugging. Do not use -d for a real
game!
* Log in as deity POGO with password peter. This guide assumes
you use the included client `empire', but other clients should
work as well.
For help, try `info'.
To change the deity password, use `change re <password>'.
* Create countries with `exec newcap_script'.
Your game is now up!
Naturally, there's more to running a real game than that, but that's
beyond the scope of this file.
