Is there a way to create variables using strings?

local String

for x = 1, #Players do
	for i = 1, 2 do
		String = "Player_" .. x .. "_Card_" .. i
		print(String)
	end
end

In my game each player has 2 cards, I want to represent these cards via an index in an array.

Player_1_Card_1 = Shuffled_Deck[1]
Player_1_Card_2 = Shuffled_Deck[2]

Is there a way to create these variables during runtime? Creating these variables during runtime would greatly reduce the amount of code needed.

There’s a ‘hacky’ way you can using function environments, as seen in this example:

local function declareVar(key, value)
	local env = getfenv()
	env[key] = value
	
	setfenv(1, env)
end


for i = 1, 10 do
	declareVar("Player"..i, 2)
end

Although I would not recommend it.

However, could you not just use a dictionary to store the player’s cards with the dictionary’s keys being the player instances?

local playerCards = {}

playerCards.C_Sharper = {}

playerCards.C_Sharper.Card1 = Shuffled_Deck[1]
playerCards.C_Sharper.Card2 = Shuffled_Deck[2]

You can also utilize for loops to manipulate the data inside of the dictionary, instead of writing it like this.

Just use a dictionary instead.

Your right, using dictionaries would be better.
