Redeem Code System

Hey developers,

Today i decide to release a very simple redeem code system !
What is redeem code ?
This is a user interface, where you can type a certain code and receive a reward !

This pack include:

  • The complete Ui design, already fully programmed
  • All required sounds
  • All leaderstats currency + Save
  • The code system & programmation

File: Redeem Code.rbxl (41,5 Ko)

How to use it ?

Open the “Codes” Script in the ServerScriptService and follow the instructions.
Everything is explained, easy and fast to edit.
You can change the Ui placement / design how you want, just take care to don’t break the script unless you are able to edit it.
:warning: It require to have the place published on a game with api enabled to access datastore save system.

I know how to make it, but I’ll take only to use the Gui Images

You made them or you take them from another location? (and, say if you know where to find anyone)

Thanks!

I taken the Icon from “FlatIcon” and everything else are roblox Ui ^^

Ok, Thanks so much! :smiley: .

A thing I’d like to mention, it’s not recommended to check if a code exists by having a remote event instance in a folder as the code name, it’s inefficient doing so. Instead, you can use tables to determine if it exists and is redeemable.

Adding on to this, you should be using Remote Functions instead of Events. Invoke the server while passing the code that was typed and have the server check a table (which should not be passed onto the client) to see if the code is valid. And if it is, return true. If not, return false. Depending on what was returned, you can then tell the client if the code is valid or not by playing the sound, etc. If you give the client access to all tot the codes, any exploiter can easily take advantage.

I just can add:
if Code ~= nil and Coins ~= nil and Gems ~= nil and Code.Value == false then
Code.Value = true
Reward Code

So it will verify if the code value is false in server side and stop exploits if they try to fire the event or change the code value.

A reminder to store the codes in a folder that is not replicated as exploiters can access it.
