I'm trying to make a simple python script, but my incredible ineptitude with python (an inability to find comprehensive for Civ4's python functions) is causing me problems.

Using onCombatResult . . .

1. I need to get the location (iX, iY) of the victorious unit that triggered onCombatResult.
2. I need to use CyMap().plot(iX, iY).changeCulture (pWinner, 2, False) to alter the culture of the tile the battle was found on.

I'm currently using the following code in CvEventManager.

def onCombatResult(self, argsList):
'Combat Result'
pWinner,pLoser = argsList
playerX = PyPlayer(pWinner.getOwner())
unitX = PyInfo.UnitInfo(pWinner.getUnitType())
playerY = PyPlayer(pLoser.getOwner())
unitY = PyInfo.UnitInfo(pLoser.getUnitType())
iX = unitx.getX()
iY = unitx.getY()
CyMap().plot(iX,iY).changeCulture(playerX, 2, False)
if (not self.__LOG_COMBAT):
return
if playerX and playerX and unitX and playerY:
CvUtil.pyPrint('Player %d Civilization %s Unit %s has defeated Player %d Civilization %s Unit %s'
%(playerX.getID(), playerX.getCivilizationName(), unitX.getDescription(),
playerY.getID(), playerY.getCivilizationName(), unitY.getDescription()))

It doesn't seem to be working. :(

Doesn't case matter? If so, you have unitx.getX(), but earlier it is: unitX = ...
Anyway, the plot can be gotten directly from pWinner, so no need for unitX/x to exist. Just use this instead:
iX = pWinner.getX()
iY = pWinner.getY()

Thanks. I finally got it to work. My naval mod can now proceed. :)

Why don't you just use the plot instance which is built into the unit.
def onCombatResult(self, argsList):
'Combat Result'
pWinner,pLoser = argsList
playerX = PyPlayer(pWinner.getOwner())
unitX = PyInfo.UnitInfo(pWinner.getUnitType())
playerY = PyPlayer(pLoser.getOwner())
unitY = PyInfo.UnitInfo(pLoser.getUnitType())
pWinner.plot().changeCulture(pWinner.getOwner(), 2, False)
if (not self.__LOG_COMBAT):
return
if playerX and playerX and unitX and playerY:
CvUtil.pyPrint('Player %d Civilization %s Unit %s has defeated Player %d Civilization %s Unit %s'
%(playerX.getID(), playerX.getCivilizationName(), unitX.getDescription(),
playerY.getID(), playerY.getCivilizationName(), unitY.getDescription()))

... to alter the culture of the tile the battle was found on.

Perhaps there is a little mistake between Winner/Looser and Attacker/Defender . The tile where the battle was found on is the tile of the defender , not necessary the winner plot ( and probably more often the looser plot ) . However , i don't know an easy way to get this plot .

Tcho !

EDIT: pUnit.isAttacking() seems to be the good test to check who is the defender , but i've never used it .
