Twitter Code Gui

WHAT DO I WANT TO ACHIEVE?

I want to have a code gui that you can press redeem to redeem the code.

HOW DOES IT WORK?

There would be a separate script that handles all the code rewards (in this script you can add and remove codes, make codes automatically expire, and make custom rewards such as give a player a sword give some cash or multiple different currencies)

NOTE: Can only be redeemed once (but can be re-redeemed if allowed)

FINAL:

Pops up a cool notification saying you redeemed…

Look on Youtube. There are many tutorials on how to do this.

You can use a table with valid codes and use string.match to find out if what was typed in equals a code.

ik but how would i save it so people cannot redeem it more than once

#5

Use datastores :shallow_pan_of_food:

#6

You can use TexBoxes.

Scroll down to see how you can achieve this.

ik but how can i save a code to a datastore?

#8

This is easy to do, note that you should not store the codes on the client.
Look it up on YouTube or script your own. You can use a free model if your new to Studio.

you just need to save the codes the user has inputted successfully and check them, you can add a metatable and add _index so when the user inputs a valid code that hasn’t been inputted yet you get the message

#10

you know datastores are for leaderstats i am not reallt experienced in the code data

#11

Datastoores are for data persistence in general.

#12

Use a remote function and detect whether the code was valid or not.

#13

Ok, the first thing you want to do is establish valid codes, you can do that by adding a series of stringValues in a folder in replicatedstorage, then you can add a script like this one in the textbox.

script.Parent.FocusLost:Connect(function()
	local text = script.Parent.Text
	for i , v in pairs(game.ReplicatedStorage.Folder:GetChildren()) do
		if v:IsA("StringValue") then
			if string.match(text , v.Value) then
				print("code redeemed")
			end
		end
	end
end)

ik but how to make it be used only once

#15

make a local table with the codes inputted so far and add an additional for loop with an if statement to check if said code has been inputted already.

#16

You can do this try it:

local codes = {
    "CodeHere";
    "Code2Here";
    "CodeAgain"
}

local textBox = --whereever it is located

for _, code in pairs(codes) do
    if textBox.Text == code then
        table.remove(codes,code)
        --rest of code here
    end
end

saaving it to datastore, like this

local DataStoreService = game:GetService("DataStoreService")
local codeStore = DataStoreService:GetDataStore("PlayerCodes")
local codes = {
  [1] =  "CodeHere";
   [2] = "Code2Here";
    [3] ="CodeAgain"
}
if not codestore:GetAsync(Player.Name) then
codestore:SetAsync(codes)
end
local textBox = --whereever it is located

for _, code in pairs(codestore:SetAsync(codes)) do
    if textBox.Text == code then
        table.remove(codestore:SetAsync(codes),code)
        --rest of code here
    end
end

if there is no past registry of codes the player inputed, the script adds the list of codes to the datastore.

Just listen to @boyparis he is telling you what to do.

  1. have a Textbox on the client where the player inputs code
  2. fire remote function to the server with the inputted code
  3. check if the code is a valid code (search a table or something)
  4. check if the user already redeemed the code, by checking a datastore (an easy way is to make the key the code and just have a bool value)
  5. if they haven’t redeemed the code, then set the datastore value to true
  6. give them a prize and return true to the RemoteFunction so the client can display UI

I watched this video (Roblox Scripting Tutorial: How to Script Twitter Codes - YouTube) now I know how to save the codes but how would I let the code be reused when i let it be reused so its one time use but then i let it be reused
