[Freeciv-Dev] [bug #20361] Pathfinding may prefer move+attack to simply attacking adjacent target

2013-01-13 Thread Silas Brill
Follow-up Comment #4, bug #20361 (project freeciv):

That could be done by treating the final step (onto the enemy-occupied tile)
as having the same movement cost regardless of direction - basically, ignore
roads and rivers on enemy-occupied tiles.

Details:

I have a dragoon in a city on a hill, and I want to use that dragoon to attack
a cannon on a diagonally adjacent hill.  However, the target hill has a river,
which seems to be throwing off the pathfinding.

+-+-+
| Hill+River (Cannon) | Plains  |
| Grassland+River | Hill+City (Dragoon) |
+-+-+

When I try to attack the cannon, the dragoon opts to move through the
Grassland+River tile, which would surely by the right move if the other hill
were not occupied.  However, in this case such a move results in my dragoon
stepping outside the safety of the city into a relatively hard-to-defend
grassland tile, and throwing one of my cities into disorder for a turn because
I'm running a democracy in the civ2 ruleset.

(I also have a musketeer in that city, which is able to attack without
triggering this bug, but when I do that the cannon wins the fight.  I'm not
sure whether that's another bug or there's some rule I'm missing that would
make that make sense.)

I've attached a savegame - the city in question is Mixcoac.
