[BNW] Question about obtaining map size

[CommunistMountain]

If I want to make an lua script which checks for map size (in this case, Duel) before creating a certain building, should I use the following? (I made a different building for different mapsizes in order to scale their effect by map size.)

function addBuilding(vHexPos, iPlayer, iCity, artStyleType, eraType, continent, populationSize, size, fogState)

       local iBuildingDuel = GameInfoTypes.BUILDING_BLAH_DUEL

       local player = Players[iPlayer];

       local city = player:GetCityByID(iCity);

       local sizeofworld = worldsizes[Map.GetWorldSize()];

       if sizeofworld == GameInfo.Worlds.WORLDSIZE_DUEL.ID then

         city:SetNumRealBuilding(iBuildingDuel, 1);

       end

end

Events.SerialEventCityCreated.Add(addBuildingDuel)

Edit: added the whole code instead of just that part.

Edit 2: Nevermind, I found out how. But I have another question... the above was for spawning a free, hidden building, but how would I go about replacing a particular building with my own building based on map size? I would have used XML to simply change that one parameter I want changed if I didn't have to factor in map size... so now I'm creating buildings from scratch.

Edit 3: Nevermind, I found out how as well. How do I delete this post
