Help with getting Plot in Python

Thorn · Mar 18, 2007

I'm (still) trying to learn Python and I have a basic question. If a certain unit dies (ie, a warrior) and you want to know (and store) what plot he died on, how do you do that? So far I've been able to use onUnitKilled to pop up a message when a warrior dies. Hey, it's a start!

I'm a programmer by trade but not in Python. However, as with spoken languages you can figure a lot from other languages, so prepare your grain of salt.

First, Apolyton has a good start at a cIV Python reference that can really help.

From the CyUnit object argument to the event, you can get its X and Y coordinates on the map. Use those with the "global context" to acquire the CyPlot.

Code:

unit, iAttacker = argsList
map = gc.getMap()
plot = map.plot(unit.getX(), unit.getY())

Thanks for the response! That's kind of the approach I was taking but it doesn't seem to be working. :mad:

Also, is there a way to print out values in-game on the screen for debugging? I would like to print variables on screen to check their values.

Can you define "not working"? Make sure you have logging enabled in the cIV.ini file. It should tell you the error, file, and line number.

Make sure you have

Code:

gc = CyGlobalContext()

at the top of your file.

Here's an example of printing a value to the screen (in this case an integer):

Code:

iGameTurn = 50
szMessage = "Game Turn %d" %(iGameTurn)
CyInterface().addMessage(CyGame().getActivePlayer(), True, 10, szMessage, "", 2, None, ColorTypes(8), 0, 0, False, False)

There's a much simpler method, but I haven't tried it and don't know how to enable it. I assume in the ini file as well, so you might give it a shot. This is what cIV uses for its debugging messages.

Code:

CvUtil.pyPrint(message)

I still can't seem to grab the plot that the unit dies on. Here's the code I have in my CustomEventManager file:

Code:

	def onUnitKilled(self, argsList):
		'Unit Killed'
		objUnit = argsList[0]
		map = gc.getMap()
		# plot = map.plot(unit.getX(), unit.getY())
		if(objUnit.getUnitType() == gc.getInfoTypeForString("UNIT_WARRIOR")):
			self.popup("", "A warrior died...")
			CyInterface().addImmediateMessage("A Warrior died...", "") 
			iGameTurn = 500
			szMessage = "Game Turn %d" %(iGameTurn)
			CyInterface().addMessage(CyGame().getActivePlayer(), True, 10, szMessage, "", 2, None, ColorTypes(8), 

0, 0, False, False)

The line: plot = map.plot(unit.getX(), unit.getY()) seems to cause problems.
Everything else works okay in the game (I get the popup messages).
By the way, I do have the gc = CyGlobalContext() line at the top

Actually, if I correct the line: plot = map.plot(ojbUnit.getX(), objUnit.getY()), it doesn't causes errors. :mischief:

But, now nothing works. Not even the popup messages...

gc.getMap() is not a valid function... What you'll want is

Code:

CyMap().plot(objUnit.getX(),objUnit.getY())

Bummer, it's listed as such at the Apolyton site.

And yes, you must use objUnit to match the variable name you declared above. My code declared it as

Code:

unit, iAttacker = argsList

Python, and other programming languages, are very precise when it comes to naming things -- unlike humans. You can refer to me as EF and I'll know what you mean. Of course, Edward Francis might get confused.

Code:
CyMap().plot(objUnit.getX(),objUnit.getY())

That seemed to do the trick! I used this code and was able to print values for mx and my. I'm assuming the numbers printed were the Plot x,y coordinates on the map...

Code:

mx = objUnit.getX()
my = objUnit.getY()

Thanks for the help EmperorFool & IVZanIV! :goodjob:

And yes, the precise naming thing can be frustrating at times

pPlot = unit.plot()
