Finding a Civ's UB (and its default building) with lua

[turingmachine]

Okay, I'm wondering if you guys can help me out with something.

In Civ IV with python I could do something like:

civtype = pPlayer.getCivilizationType()
for iBuilding in range(gc.getNumBuildingClassInfos()):
	iUniqueBuilding = gc.getCivilizationInfo(civtype).getCivilizationBuildings(iBuilding);
	iDefaultBuilding = gc.getBuildingClassInfo(iBuilding).getDefaultBuildingIndex();

My lua isn't as good as my python. Can something similar be done in Civ V (and if so, any advice as to how to write it in lua)?

Something like this:

function GetUbOverride(iPlayer)
	local player = Players[iPlayer];
	local civType = GameInfo.Civilizations[player:GetCivilizationType()].Type;
	local constraint = string.format("CivilizationType = '%s'", civType);
	for buildingOverride in GameInfo.Civilization_BuildingClassOverrides(constraint)() do
		-- only first
		return buildingOverride;
	end
	-- ... or nothing
	return nil;
end

function DoSomething(iPlayer)
	buildingOverride = GetUbOverride(iPlayer);
	if buildingOverride ~= nil then
		local originalClass = buildingOverride.BuildingClassType;
		local UbType = buildingOverride.BuildingType;
	end
end
GameEvents.PlayerDoTurn.Add( DoSomething );

I didn't test, but it should be close.

		local UbType = buildingOverride.BuildingType;

Wow, thanks a lot!!!!!!!!! I had given up on this.

On follow up question. I see at the end I get the original building class, but how can I get the original building type. Basically, I need to check a city and see if it has the default building and if so replace it with the UB (all of which I know how to do if I have the original building stored to compare).

That would be:

local defaultBuildingType = GameInfo.BuildingClasses[originalClass].DefaultBuilding;

Basically you can access any table and index it with a column as long as that column has unique values. E.g.:

local defaultBuilding = GameInfo.Buildings[defaultBuildingType];

Because the Type is unique for Buildings.
