f6c87d21ff Factor out common land unit fire code into lnd_fire()
This takes care of a number of bugs / inconsistencies:

* Resupply before fire: fire command did not require unit to be in
  supply, and resupplied shells.  Everywhere else (return fire,
  support and interdiction) the land unit had to be in supply after
  resupply of everything.  Unify not to resupply anything and not to
  require being in supply.  This is consistent with ships and sectors.

* Resupply after fire: fire command resupplied shells after active
  fire.  Unify not to do that.  This is consistent with ships and
  sectors.

* When a land unit returned fire to multiple attackers, quiet_bigdef()
  charged it ammo for each one.  Finally, it was charged one shell
  more by use_ammo().  Except only the first land unit got charged
  there in fact, because buggy add_to_fired_queue() entered only the
  first land unit into the defender list.  Fix add_to_fired_queue()
  and change quiet_bigdef() not to charge ammo, just like for ships
  and sectors.  This charges only one shell instead of the true ammo
  use, which is wrong, but consistent with ships.

* lnd_support() tallied support damage unrounded.  Unify to round
  before tally.

69f441ef39 Change test whether a land unit is artillery
Test for land unit firing damage instead of range, for consistency
with ships.

e8595066d1 Factor out common fortress fire code into fort_fire()
This takes care of a number of bugs / inconsistencies:

* sb() fired support even when there were not enough mil.

* Shell resupply bugs: multifire() and quiet_bigdef() resupplied
  shells before checking all other requirements and could thus get
  more shells than actually needed.

Rename landgun() to fortgun() for consistency.

0219bf086a New unit stat development functions
The macros defining unit stat development in tech are somewhat
inconvenient to use.  Define more convenient functions, and hide away
the macros near the function definitions.

3290e87576 Get rid of the need to fix up lchr[].
Mil are not required for building units since 4.0.0.  l_mil was still
initialized to l_item[I_MILIT], and used instead of that in a couple
of places.  Fix those, and remove the initialization.

3d2518a724 Get rid of src/lib/common/land.c
There are several files with land unit subroutines.  This one is in an
awkward place: it depends on stuff from ../subs, which contributes to
libcommon.a's ugly dependencies.  Move its contents to logical places
(use internal linkage where possible), and remove it.

e42053d928 Break inclusion cycle: prototypes.h and commands.h included each
other.  Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special).  New header types.h to
help avoid inclusion cycles.  Sort include directives.  Remove some
superflous includes.

99fc82b94d (LND_AMM): Became weird in 4.2.3: ammo use depends on l_dam if l_ammo
is non-zero; actual value of non-zero l_ammo was unimportant.  Side
effect: it substantially increased ammunition consumption at high
tech, because the change made the value increase with tech.  Back out
4.2.3's change, just use l_ammo.  This lets deities customize
ammunition consumption independent of damage.  Remove second
parameter.  Callers changed.

36e41e5ac9 (lnd_sel): The marching code gets confused when trains and non-trains
march together.  Disallow for now.

(lnd_mar_one_sector): Use lnd_mobtype() to check whether rail's
needed.

602b2a07cb (lnd_fortify): The previous revision could break under conditions that
currently don't occur.  Fix anyway.

is zero.

490b4fa5ff Revert the previous revision, it doesn't make sense. 2006-06-16 05:42:52 +00:00
2ecc85b541 (attack_val, defense_val): These functions overestimate unit strength,
because they ignore three facts.  Firstly, mil casualties decrease
strength linearly, while unit casualties decrease it quadratically
(unit strength scales with mil * eff).  Secondly, casualties decrease
strength proportional to the combat multiplier, hence twice as much
mil are more powerful than double multiplier.  Thirdly, units break
and retreat.  Change the estimate from mil * mult to mil * sqrt(mult).
Improves things in simulations, hope it works out in practice as well.
Closes #682571.

(lnd_mobcost): Use it, remove last parameter.  Callers changed.  This
fixes mobility use of trains when retreating, both for retreat orders
and for failed morale checks.
(retreat_land1): Fix test for impassable terrain.  Before, trains
could retreat off rail.
(lnd_take_casualty): Test for impassable terrain.  Before, trains
could retreat off rail.

55ff194f7f (lnd_pathcost): New, factored out of lnd_mobcost().
(att_reacting_units): Use it.  Fixes overcharging of inefficient
units.  Broken when Empire3 changed land unit mobility use not to
depend on efficiency, except for supply units.
(lnd_sweep): Use it.  No functional change.

(speed_factor): New, factored out of lnd_pathcost() and shp_mobcost().
2006-06-08 20:43:13 +00:00
5ad86bc7ce 4.0.2 made land unit mobility costs differ significantly from normal
move costs, but failed to make A* use these costs.  This broke land
unit path finding.  Fix:
(MOB_ROAD, MOB_MOVE, MOB_MARCH): Split MOB_ROAD into MOB_MOVE and
MOB_MARCH.  Users changed.
(lnd_mobcost, sector_mcost): Move minimum mobcost logic to
sector_mcost(), where it is visible to A*.  Also fixes unit reaction
path cost.

(lnd_path): Fix confusing message: don't claim there's no path when
all we really know is that there's no railway.

e627f31c10 (attack_val): Don't truncate or round intermediate values, truncate
final result, like defense_val() does.

appropriate here.
2006-05-21 09:23:42 +00:00
2732ac5d1d (lnd_getmil, total_mil): Trivial, inline into callers and remove. The
abstraction from actual land unit mil encoding provided by them was
too leaky to be relied upon anyway.
