How can i make a code system like the video below?

Help and Feedback Scripting Support
#21

Thats going to save if i leave?

#22

That’s updating the values, to make the datastore:
(IDK if this works with bools but I think it does.)
Edit: Different scripts


local datakey = "ddtht664tge54"

local DataStoreService = game:GetService("DataStoreService")

local playerData = DataStoreService:GetDataStore(datakey)

game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "stats"
	leaderstats.Parent = player
	
	local gold = Instance.new("BoolValue")
	gold.Name = "code"
	gold.Parent = leaderstats
	
	local data
	local success, errormessage = pcall(function()
		data = playerData:GetAsync(player.UserId.."-code") 
	end)
	
	if success then 
		gold.Value = data
	else
		print("Error while getting your data")
		warn(errormessage)
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	
	local success, errormessage = pcall(function()
		playerData:SetAsync(player.UserId.."-code", player.leaderstats.code.Value)
	end)
	
	if success then
		print("Data successfully saved!")
	else
		print("There was an error while saving the data")
		warn(errormessage)
	end
	
end)
#23

Thats gonna save this :

game.Players.PlayerAdded:Connect(function(player)
x=0
player.Chatted:Connect(function(msg)
if msg == string.lower(“!code sin”) and x == 0 then
x=1

		player.leaderstats.Points.Value = player.leaderstats.Points.Value + 40
		
	end
end)

end)

??

#24

It will save the boolvalue. (If the player has used the code or not)

#25

And that works with this script:

 game.Players.PlayerAdded:Connect(function(player)
code = player.stats.code
      player.Chatted:Connect(function(msg)
            if msg == string.lower("!code sin") and code.Value == false then
code.Value = true
                -- do stuff with msg and player
            end
      end)
    end)
#26

Do i put that DataStore on the same script?

#27

Different scripts, one saves/loads the bool value (the long script), and the short one handles the thing that happens when the player uses the code.

#28

So what if i wanna have multiple codes but keep the old once active?

#29

Whats this

local datakey = “ddtht664tge54”

#30 
 game.Players.PlayerAdded:Connect(function(player)
code = player.stats.code
codeb = player.stats.codeb
      player.Chatted:Connect(function(msg)
            if msg == string.lower("!code sin") and code.Value == false then
code.Value = true
elseif msg == string.lower("!code sin2") and codeb.Value == false then
codeb.Value = true
                -- do stuff with msg and player
            end
      end)
    end)

and the datakey is just the datastore.

Does code = player.stats.code?

#33

Here is a prototype script. I have not tested it, so let me know how it works. It should save and only let you redeem once.

*removed check farther down*

edited the code a bit

#34

game.Players.PlayerAdded:Connect(function(player)
code = player.stats.code
codeb = player.stats.codeb
player.Chatted:Connect(function(msg)
if msg == string.lower(“!code sin”) and code.Value == false then
code.Value = true
elseif msg == string.lower(“!code sin2”) and codeb.Value == false then
codeb.Value = true

		player.leaderstats.Points.Value = player.leaderstats.Points.Value + 40
	end
end)

end)

#35

Try his, I’m starting to confuse myself lol.

#36

Its giving me 2 errors

My bad, I forgot to change the codesDataStore variable naming! Try this?

local codesDataStore = game:GetService("DataStoreService"):GetDataStore("Codes")
     
function saveRedeemed(playerKey, code)
	local firstTime = false
	local success, err = pcall(function()
		codesDataStore:UpdateAsync(playerKey .. "_" .. code, function(oldValue)
			local newValue = oldValue or false
			if newValue == false then
				newValue = true
				firstTime = true
			end
			return newValue
		end)
	end)
	return firstTime
end

game.Players.PlayerAdded:Connect(function(player)
	
	local playerKey = "Player_" .. player.UserId

	player.Chatted:Connect(function(msg)
		if msg == string.lower("!code sin") then
			-- do stuff with msg and player
			local redeemed, firstTime = saveRedeemed(playerKey, "sin") -- make sure if you add more codes you change the if statement AND this 
			if firstTime ~= nil and firstTime == true then
				-- give them the reward (will save 1 time only)
			end
		end
	end)
end)
#38

Thats wierd it isnt giving me any errors but its not giving me the points?

#39

Am I supposed to put player.leaderstats.Points.Value = player.leaderstats.Points.Value + 40

local codesDataStore = game:GetService(“DataStoreService”):GetDataStore(“Codes”)

function saveRedeemed(playerKey, code)
local firstTime = false
local success, err = pcall(function()
codesDataStore:UpdateAsync(playerKey … “_” … code, function(oldValue)
local newValue = oldValue or false
if newValue == false then
newValue = true
firstTime = true
end
return newValue
end)
end)
return firstTime
end

game.Players.PlayerAdded:Connect(function(player)

local playerKey = "Player_" .. player.UserId

player.Chatted:Connect(function(msg)
	if msg == string.lower("!code sin") then
		-- do stuff with msg and player ***<<<< Here*** 
		local redeemed, firstTime = saveRedeemed(playerKey, "sin") -- make sure if you add more codes you change the if statement AND this 
		if firstTime ~= nil and firstTime == true then

– give them the reward (will save 1 time only) <<<< Or Here
