Changes to Empire 4.3.20 - Tue Feb 17 18:56:53 UTC 2009
* Changes and fixes to automatic supply:
- Planes flying interception or support missions, abms intercepting
ballistic missiles, and the launch command for missiles and
anti-sats could all supply more shells than necessary, lose
shells, or conjure them up.
- Ships shooting down marine missiles could supply more shells than
necessary, or lose shells.
- Supply ships could conjure up shells when firing guns using
multiple shells, or launching torpedoes, or dropping depth
charges, or shooting down marine missiles. No supply ships
capable of doing that exist in the stock game.
- Supply engineers could conjure up shells when laying mines. They
don't exist in the stock game.
- load, lload and supply could supply land units with enough food
from the sector containing them to starve the sector.
- Sectors were charged too much mobility for moving supplies
sometimes.
- Land units serving as supply source no longer draw supplies
recursively, because the bugs there are too hard to fix to be
worth it.
- Defending and reacting units checked whether they could draw
supplies, but failed to actually draw them.
- load, lload, supply, assault and board no longer supply land
units from ships carrying them. This feature, added in 4.0.14,
was inconsistent with other ways to supply.
- Don't use automatic supply to avoid starvation at the update. It
adds complexity to the update. How much good it does to players
is highly doubtful; certainly nobody can rely on it. It isn't
covered by the starvation command. Ships or land units could
steal enough food from their sector to make it starve.
The changes listed for load and lload are actually lies, because
supply has been disabled there since 4.3.17.
* lmine didn't work for engineers that don't use ammo. The stock
game's engineers all use ammo.
* Don't let an engineer lay mines while it is on a ship or land unit,
or in a foreign sector.
* Sectors and ships no longer need shells to fire flak.
* Use IPv4 and v6 only when suitable interfaces are configured.
* Fix turn off not to fail when the message is empty. Broken in
4.2.20.
* Don't nag the deity about game hours restriction in force all the
time.
* Tell deity when the game is down, just like players. Also make the
information available in xdump, as game selector down.
* Corrupt mailboxes could crash the server.
* Fix reject accept. Broken in 4.3.4.
* If a player was at a prompt when the deity turned the game down, he
was allowed to enter one more command.
* Air defense is no longer separate from interception. Putting a
plane on air defense now merely changes where it intercepts.
Separate air defense added too much pointless complexity. Its
implementation violated design assumptions of the intercept code.
Because of that, the same plane could intercept both an air defense
mission and the planes that triggered it, and the damage it
received in the first interception was wiped out.
* Intercept the same all along the flight path. In each sector, any
country owning the sector, a surface ship or a land unit there gets
to intercept. Before, only the sector owner got to intercept,
except for the assembly point and the target sector. In the target
sector, any country owning surface ships or land units got to
intercept in addition to the sector owner. Thus, a sector owner
with surface ships or land units there got to intercept twice. The
sector owner did not get to intercept at the assembly point,
even when it was the target sector.
* Spotting rule changes:
- Ships and land units now spot overflying planes along all of the
flight path instead of just the target sector, and no longer
report allied planes.
- Planes now spot ships and land units only when flying recon or
sweep, and along all of their flight path instead of just the
target sector. It still takes a spy plane to identify ships and
land units.
- Planes now spot ships and land units in a sector even when all
planes abort there.
- Planes now spot all foreign ships and land units, not just
hostile ones.
* Fix SAM interception for intercepts other than the first.
* Fix air defense and flak over sectors allied to the planes. Air
defense was broken in Empire 2. Flak was broken in 4.2.8.
* Establishing contact by spotting planes from sectors didn't work.
* Fix reconnaissance patrols to use sonar when any capable plane is
present. Before, all planes had to be capable.
* Fix recon and sweep not to spy after all spy planes are gone.
* Fix a bug that made multiple clients running on the same Windows
machine interfere with each other. Broken in 4.3.11.
* Fix enforcing game hours for players already logged in. Broken in
4.3.19.
* Fix distribution not to abandon a distribution center by exporting
the last military.
* Many fixes to load, unload, lload and lunload:
- Now usable for deities.
- Plug loopholes that let you steal foreign commodities by making
load/lload unload and unload/lunload load through use of negative
amount arguments.
- Fix not to let you give away civilians.
- You can't use lload in foreign sectors or lunload with foreign
land units anymore. Loading stuff in foreign sectors was
prohibited already for ships.
- lload and lunload now work on foreign land units only when
they're explicitely named by uid. This matches behavior of load
and unload.
- Fix to test relations of foreign object's owner to player instead
of the other way round.
* Make sure land units with maximum mobility can attack mountains.
* Fix land unit attack mobility cost. Broken in 4.3.6.
* Conditions comparing string-valued selectors like wing to unquoted
values are now interpreted more smartly. Before, unquoted strings
were prone to be interpreted as selector names even when that made
no sense. You still have to disambiguate truly ambiguous cases
like w=w for planes, e.g. as wing=w or w='w'.
* Fix reporting of shot spies in news. Broken in 4.3.16.
* Remove econfig key mission_mob_cost. Questionable feature, and
hasn't been used in a long time.
* Reserve and escort missions now have an op-area, like all the other
missions.
* Land units now react only when on a reserve mission. The lrange
command is gone.
* Fix a bug that could mess up mission op-area when the range of
ship, plane or land unit on the mission decreases, e.g. through the
range command.
* Reserve missions no longer give a bonus to reaction range.
* Info file fixes.
* Code refactoring and cleanup.
Changes to Empire 4.3.19 - Sun Dec 7 23:15:34 UTC 2008
* LWP doesn't work with Darwin due to OS bugs, avoid it for now.
* Don't let ships double-retreat first on 'i' (injured) and then on
'h' (helpless) when shelled.
