Lua Checking if a city has a building.

[turingmachine]

How do I check if a city has a specific building?

I see:

GetNumActiveBuilding
GetNumBuilding
GetNumBuildings
GetNumFreeBuilding
GetNumRealBuilding

I'm not really sure what the difference is.

Do I do something like:

local CASTLE = GameInfoTypes.BUILDING_CASTLE

if pCity:getNumBuilding(CASTLE, 1) == true then

Try this:

if (pCity:GetNumBuilding(CASTLE ) > 0) then

Try this:

if (pCity:GetNumBuilding(CASTLE ) > 0) then

Thank you. Is there also a way to check if a city is connected to the capital (has a trade route) with Lua?
