A simple Roblox shop usually has two parts: a GUI for the player and a script that shows/hides it or handles purchases. A basic setup is to put a ScreenGui in StarterGui, add a Frame for the shop, add buttons for opening/closing it, and use a LocalScript to toggle visibility.

Basic setup

Start with this structure in Roblox Studio:

  • StarterGui
  • ScreenGui
  • Frame named ShopFrame
  • TextButton named OpenShopButton
  • TextButton named CloseButton

A common beginner pattern is to keep ShopFrame.Visible = false at first, then use buttons to open and close it.

Simple open and close script

Put a LocalScript inside OpenShopButton:

lua

local openBtn = script.Parent
local shopFrame = openBtn.Parent:WaitForChild("ShopFrame")

openBtn.MouseButton1Click:Connect(function()
	shopFrame.Visible = true
end)

Put another LocalScript inside CloseButton:

lua

local closeBtn = script.Parent
local shopFrame = closeBtn.Parent

closeBtn.MouseButton1Click:Connect(function()
	shopFrame.Visible = false
end)

That is the core of a working shop UI: one button opens it, one button closes it.

Adding items

After the UI works, you can add item buttons inside the frame. A scalable approach is to store item data in a table and generate the buttons dynamically instead of building every item by hand.

Example idea:

lua

local items = {
	{Name = "Sword", Price = 100},
	{Name = "Shield", Price = 150},
}

Then loop through that table to create shop entries in your GUI.

Buying items

There are two common shop types:

  • In-game currency shop, where players spend coins or points.
  • Robux shop, where players buy developer products or game passes.

For currency shops, the client should only request a purchase, while the server should verify money and give the item. For Robux purchases, use Roblox’s product or pass systems rather than trusting the client alone.

Clean beginner path

If you want the fastest path, build it in this order:

  1. Make the shop frame and open/close buttons.
  2. Make the open/close scripts work.
  3. Add item buttons.
  4. Connect item buttons to purchase logic.
  5. Save player progress if needed.
  6. Polish the UI for different screen sizes.

A good first version is just a menu that opens, shows 3 items, and closes cleanly. Once that works, you can upgrade it into a full system.

Small example

If you wanted a tiny shop for coins, the flow would be:

  • Player clicks “Shop.”
  • Frame appears.
  • Player clicks “Buy Sword.”
  • Game checks whether they have enough coins.
  • If yes, subtract coins and give the item.

That pattern is what most Roblox shop systems build on.

TL;DR: Make a ScreenGui, put a hidden ShopFrame inside it, add open/close buttons, use LocalScripts to toggle visibility, then add item data and server-side purchase logic.
