In Part 2, we created buttons that let players unlock items. But right now, they’re free — which makes the Tycoon too easy! In this part, we’ll add cash (currency) so players need to spend money to buy items.

Step 1: Set Up Leaderstats (Player Data)

We’ll store each player’s money in a leaderboard (the top-right corner of the screen).

1. In ServerScriptService, insert a new Script.
2. Rename it: Data.
3. Add this code:

-- Data Script (handles player stats like money)
game.Players.PlayerAdded:Connect(function(player)
    -- Create Leaderstats folder (must be lowercase "leaderstats")
    local folder = Instance.new("Folder")
    folder.Name = "leaderstats"
    folder.Parent = player

    -- Create Cash value
    local cash = Instance.new("IntValue")
    cash.Name = "Cash" -- appears on leaderboard
    cash.Value = 0     -- start with 0
    cash.Parent = folder
end)

Now when you press Play, you’ll see a leaderboard in the top-right corner with “Cash = 0.”

Step 2: Add Prices to Buttons

Each button should have a price so players must pay to unlock items.

1. Select your Button in the Explorer.
2. In Properties → Attributes, click ➕.
3. Add:
   • Name = Price
   • Type = Number
   • Example Value = 50

This means unlocking this button costs 50 Cash.

Step 3: Update Plot Handler Script

Go back to your PlotHandler script (where you detect button touches).
Find the section where the player touches the button and add:

-- Get price from button
local price = button:GetAttribute("Price")

-- If no price set, item is free
if price and player.leaderstats.Cash.Value < price then
    warn("You cannot afford this item!")
    return
end

-- Deduct price from Cash (only if price exists)
if price then
    player.leaderstats.Cash.Value -= price
end

---

Step 4: Test the System

1. Press Play.
2. Step on the button with 0 Cash.
   • You should see a warning: “You cannot afford this item!”
   • The item won’t appear.
3. Give yourself Cash (in Server View only):
   • Switch to Server mode in Studio.
   • In Explorer → Players → [YourName] → leaderstats → Cash → set value to 500.
4. Switch back to Client mode.
5. Step on the button again.
   • The item appears
   • Your Cash decreases (e.g., from 500 → 450).

Recap

• Created a leaderstats system to track Cash.
• Added a Price attribute to buttons.
• Checked if players have enough money before unlocking items.
• Deducted money when they buy items.

Next Step

Right now, players start with 0 Cash. In the next part, we’ll create a dropper system so players can earn money automatically and keep upgrading their Tycoon.
