With RAILWAYS, highway-like sectors double as rail. They need to be
at least 5% efficient to be operational, and then they additionally
extend rail into adjacent sectors that are at least 60% efficient.
New opt_RAILWAYS, SCT_HAS_RAIL(), sct_rail_track(). Update
sector_mcost(), bp_neighbors(), lnd_mar_one_sector() for RAILWAYS
mobility rules. Update sinfra(), spyline(), satdisp_sect() to show
rail track instead of rail infrastructure for RAILWAYS.
New virtual sector selector track, implemented by nsc_sct_track().
Planes and land units on ships are sold along with the ship, but trade
showed them only when SHOWPLANE was enabled. Show them always.
Planes on land units are not sold along with the land unit, but trade
showed them when SHOWPLANE was enabled. Don't.
The abstract idea of tying ships and land units to a logistical tether
is sound, the concrete implementation as option FUEL is flawed. It
adds too much busy-work to the game to be enjoyable. It hasn't been
enabled in a public game for years. The code implementing it is ugly,
repetitive, and a burden to maintain.
Remove selector fuel from ship_ca[] and land_ca[], and selectors
fuelc, fuelu from mchr_ca[] and lchr_ca[]. Remove fields fuelc, fuelu
from ship.config and land.config.
Remove command fuel from player_coms[].
Deprecate edit key 'B' in doship(), dounit(), and don't show it in
pr_ship(), pr_land().
Drop opt_FUEL code from build_ship(), shi(), sdump(), ship_damage(),
show_ship_stats(), do_mob_ship(), nav_ship(), build_land(), land(),
ldump(), land_damage(), show_land_stats(), do_mob_land(),
resupply_all(), resupply_commod(), get_minimum(), has_supply(),
unit_list(), vers().
Remove opt_FUEL, fuel_mult, struct shpstr member shp_fuel, struct
mchrstr members m_fuelc and m_fuelu, M_OILER, struct lndstr member
lnd_fuel, struct lchrstr members l_fuelc and l_fuelu, fuel(), and
auto_fuel_ship().
(opt_AUTO_POWER, update_power): New.
(update_main): Implement AUTO_POWER.
(powe): Disable power new when AUTO_POWER is on.
(powe): New power update.
(gen_power): Compute power into buffer passed by caller, make write to
power file optional.
instead of opt_DEFENSE_INFRA.
(improve): Test for it.
(show_sect_build): Show only enabled infrastructure.
(opt_DEFENSE_INFRA): Remove. Deities can edit infra.config instead.
(improve): Dumb down prompt.
files item.config, product.config, sect.config, infra.config.
(empfile): Declare the new config files. Reorder table entries so
that read_builtin_tables() reads the config files in the right order.
(bigcity_dchr, opt_BIG_CITY, init_dchr): Remove. Deities can edit
sect.config instead.
(show_nuke_capab, vers, xdvisible, build.t, Options.t):
Remove opt_DRNUKE and replace with the following check
drnuke_const > MIN_DRNUKE_CONST.
Set MIN_DRNUKE_CONST to 0.001 to prevent issues with tiny values.
Change the default drnuke_const to 0.0 because in the stock game
opt_DRNUKE was disabled.
buil, show_bridge, show_tower, nullify_objects):
Remove NO_LCMS, NO_HCMS, and NO_OIL options, not used.
Functionality can be emulated by modifiying the characteristics files.
