How to make a randomized issuing city?

Help and Feedback Scripting Support
#1

I am trying to figure out how to create a randomized issuing city that is inside a randomized country. I have already made the randomized country, but I’m not the best in arrays/tables, and I’ve tried a little bit at making it show the cities inside the countries be randomized.

IssuingCities = {

["Toyuma"] = "Jaliam", "Meniexa", "Salamia";

["Reussi"] = "Northern State", "Greater Reussi", "Grand Reussi";

["Arsoftika"] = "Better Reussi", "Arkosta", "Jerfina";

["Frenicia"] = "Daytona", "Rei", "Freancies";

["Fed. Rep. Of Stalm"] = "Islamai", "Modernea";

}

without having to write 50 thousand if statements.

Best regards,
anyone who sees this lol

Is the Toyuma, Reussi, Arsoftika, Frenicia, Fed. Rep. of Stalm the countries?

#3

Yes. They are the countries. The other ones are the issuing cities for those countries. (Also to let you know its for a game that im making similar to Papers Please.)

You can use math.random to pick a random thing in the table, and # to get the number of things in a table.

local ChosenCity = ChosenCountry[math.random(#ChosenCountry)]

ChosenCountry would be the country you have picked, you can’t use this method with the countries because its not a table, its a dictionary.

uh so how do I get randomized values from a Dictionary?

#6

Alright. I’ve truly just looked at another post with the phrase “randomized values from a Dictionary” and I’ve now acquired what I needed.

Sorry it took so long, i had to test in in Roblox Studio. Anyways, here is the code:

local IssuingCities = {

	["Toyuma"] = {"Jaliam", "Meniexa", "Salamia"};

	["Reussi"] = {"Northern State", "Greater Reussi", "Grand Reussi"};

	["Arsoftika"] = {"Better Reussi", "Arkosta", "Jerfina"};

	["Frenicia"] = {"Daytona", "Rei", "Freancies"};

	["Fed. Rep. Of Stalm"] = {"Islamai", "Modernea"};

}

local function getRandomizedCityForCountry()
	local countryWithIssuingCity = {}

	local function findRandomCity(array)
		local randomNum = math.random(1,#array)
		local ChosenCity = array[randomNum]
		if ChosenCity ~= nil then
			return ChosenCity
		end
	end

	for country,arrayOfCities in pairs(IssuingCities) do
		local city = findRandomCity(arrayOfCities)
		if city ~= nil then
			countryWithIssuingCity[tostring(country)] = tostring(city)
		end
	end
	
	return countryWithIssuingCity
end

local countryPairTable = getRandomizedCityForCountry()

for i,v in pairs(countryPairTable) do
	print(i.."="..v)
end

Uh. Sorry if I’m being mean for some reason lol, but I got some inspiration from your function and…

local function RandomCityFor(country, array)
	CountryArray = array[country]
	NewCity = CountryArray[math.random(1, #CountryArray)]
	
	return tostring(NewCity)
end
#9

Can you send me the whole script?

#10 
Countries = {
	"Reussi",
	"Iraqianai",
	"Arsoftika",
	"Frenicia",
	"Fed. Rep. Of Stalm",
	"Toyuma"
}

IssuingCities = {
	["Toyuma"] = {"Jaliam", "Meniexa", "Salamia"};
	["Reussi"] = {"Northern State", "Greater Reussi", "Grand Reussi"};
	["Arsoftika"] = {"Better Reussi", "Arkosta", "Jerfina"};
	["Frenicia"] = {"Daytona", "Rei", "Freancies"};
	["Fed. Rep. Of Stalm"] = {"Islamai", "Modernea"};
}

WrongCities = {
	["Toyuma"] = {"Saliam", "Menizxo", "Satalmia"};
	["Reussi"] = {"Northern Reussi", "Better Reussi", "Old Reussi"};
	["Arsoftika"] = {"Worst Reussi", "Arstotzka", "Jerma"};
	["Frenicia"] = {"Guytona", "Ram", "France"};
	["Fed. Rep. Of Stalm"] = {"Islam", "Oldernia"};
}

local function RandomCityFor(country, array)
	CountryArray = array[country]
	NewCity = CountryArray[math.random(1, #CountryArray)]
	
	return tostring(NewCity)
end


Genders = {
	"Male",
	"Female" -- very political indeed. but i cant say "sex" or i will be shot by the robloxians at the roblox HQ
}

-- this is all redacted because no steal

return module

its a module that makes npcs spawn with data. i just removed one of the functions for redacting-ness

#11

What’s the problem with the script?

#12

Well its solved now. Thank you for helping, although!

IssuingCountries = {"Toyuma", "Reussi", "Arsoftika", "Frenicia", "Fed. Rep. Of Stalm"}

IssuingCities = {
	["Toyuma"] = {"Jaliam", "Meniexa", "Salamia"},
	["Reussi"] = {"Northern State", "Greater Reussi", "Grand Reussi"},
	["Arsoftika"] = {"Better Reussi", "Arkosta", "Jerfina"},
	["Frenicia"] = {"Daytona", "Rei", "Freancies"},
	["Fed. Rep. Of Stalm"] = {"Islamai", "Modernea"}
}

local function getRandomCountry()
	return IssuingCountries[math.random(#IssuingCountries)]
end

local function getRandomCity(country)
	return IssuingCities[country][math.random(#IssuingCities[country])]
end

local RandomCountry = getRandomCountry()
local RandomCity = getRandomCity(RandomCountry)
print(RandomCountry, RandomCity)

Here’s how I’d go about this.
