Checking if mods are activated with LUA?

Enginseer · Aug 27, 2015

Code:

GameEvents.CityCanConstruct.Add(function(iBuildingType) 
	if (iBuildingType == GameInfo.Buildings["BUILDING_MONUMENT_UP_FOOD"].ID) then
		if (isUsingBUS == true) then
			print("Cannot build Monument of Food")
			return false;
		end
	end
	if (iBuildingType == GameInfo.Buildings["BUILDING_MONUMENT_UP_LABOR"].ID) then
		if (isUsingBUS == true) then
			print("Cannot build Monument of Labor")
			return false;
		end
	end
	if (iBuildingType == GameInfo.Buildings["BUILDING_MONUMENT_UP_FAITH"].ID) then
		if (isUsingBUS == true) then
			print("Cannot build Monument of Faith")
			return false;
		end
	end
	if (iBuildingType == GameInfo.Buildings["BUILDING_MONUMENT_UP_RESEARCH"].ID) then
		if (isUsingBUS == true) then
			print("Cannot build Monument of Research")
			return false;
		end
	end
	if (iBuildingType == GameInfo.Buildings["BUILDING_MONUMENT_UP_MIGHT"].ID) then
		if (isUsingBUS == true) then
			print("Cannot build Monument of Might")
			return false;
		end
	end
	return true;
end);

function HavingMods()

		--Assumes that if this mod ID is activated then this is true? I believe?
		if (mod.ID == e3fed66f-f129-45a4-abce-a5496dc2f0c5) then

		end
	end
end

isUsingBUS = false
HavingMods()

Using the source code from the 1066 scenario and Xaragas's Compatibility coding.. I've developed a sort of file which enforces that this mod is required before any modded buildings can be built... any LUA experts know if I am doing this correctly or on the right track?

It generally works, but one caveat is that it does not work properly in multiplayer. With the current methods, the game considers no mods to be active when you are running a multiplayer modpack.

Are you trying to make a building in your mod which can't be built without the presence of another mod? What I'd do is test for the existence of something that mod adds, like a building or policy or whatever.

And how would you test the added modded building in LUA?

Could someone shed some light on this? The game never seems to respond to any of my functions...?

ViceVirtuoso has already addressed the multiplayer issue, so I'll assume you mean it doesn't work in single player.

Best thing to do is to throw some print() statements in there and see where Lua is failing during execution.

Having said that, doublecheck your comparisons:

Code:

function HavingMods()
	for _, mod in pairs(Modding.GetActivatedMods()) do
		--Assumes that if this mod ID is activated then this is true? I believe?
		if ([COLOR="Red"]mod.ID == e3fed66f-f129-45a4-abce-a5496dc2f0c5[/COLOR]) then
			isUsingBUS = true
		end
	end
end

You likely need to encapsulate the target mod ID in quotes, because the mod ID returned is a string, and you're trying to compare it to...something Lua likely can't figure out, because you've not specified it as a string.

Code:

function HavingMods()
	for _, mod in pairs(Modding.GetActivatedMods()) do
		--Assumes that if this mod ID is activated then this is true? I believe?
		if (mod.ID == [COLOR="Blue"][B]"e3fed66f-f129-45a4-abce-a5496dc2f0c5"[/B][/COLOR]) then
			isUsingBUS = true
		end
	end
end

Code:

function CityCanConstructBUS(iPlayer, iCity, buildingType)
	if (isUsingBUS == false) then
		--print("Doesn't have BUS")
		if ((buildingType ~= GameInfoTypes.BUILDING_MONUMENT_UP)) then
			return true
		else
			return false
		end
	elseif (isUsingBUS == true) then
		--print("Have BUS")
		return true
	end
end

		if (mod.ID == "e3fed66f-f129-45a4-abce-a5496dc2f0c5") then
			isUsingBUS = true
			--print("mod online")
		end
	end
end

isUsingBUS = false
HavingMods()
print(isUsingBUS)
GameEvents.CityCanConstruct.Add(CityCanConstructBUS)

Looking at previous past posts, I was able to replicate this to success. Thanks for the help!
