How do you make a building require an improvement (like Granary requires wheat)?

Well in the CvGameUtils.py file find the cannotConstruct function. Then use the city object as a reference point in a for loop that goes through the fat cross. Then check to see if the plots owner is the cities owner and see if it has the required improvement. If so return false. I'll see if I can get the code up for you.:thumbsup:

Edit or did you want resources?

Well I want it so you have to have an improvement in the cities fat cross (no resouce) in order to build the building. I meant Granary requires wheat to have a farm on it.

Umm, near as I can tell, Granary doesn't require wheat, or farms. However, the bonus requires that the city have access to wheat, corn, or rice. That access can come from trade, or a farm/plantation. Is that what you're talking about?

Well the granary doesn't ATM but I want it so you have to have a farm in the Cities fat cross.

Ok, here is your code. def cannotConstruct(self,argsList):
pCity = argsList[0]
eBuilding = argsList[1]
bContinue = argsList[2]
bTestVisible = argsList[3]
bIgnoreCost = argsList[4]

bCannotConstruct = True
if eBuilding == gc.getInfoTypeForString("BUILDING_WALLS"):
iX = pCity.getX()
iY = pCity.getY()
for iiX in range(iX-1, iX+2, 1):
for iiY in range(iY-1, iY+2, 1):
pPlot = CyMap().plot(iiX,iiY)
if pPlot.getOwner() == pCity.getOwner():
if pPlot.getImprovementType() == gc.getInfoTypeForString("IMPROVEMENT_FARM"):
bCannotConstruct = False
if bCannotConstruct:
return True

return False
and in PythonCallbackDefines.xml change USE_CANNOT_CONSTRUCT_CALLBACK from 0 to 1. :thumbsup:

Ok, thanks. :goodjob:
