How to Create a Roblox Tycoon (Part 1: Plot Assignment)

This guide will walk you through setting up the foundation for a Roblox Tycoon game in 2024. In this first part, we’ll create player plots and assign them automatically when players join the game.


Step 1: Set Up the Workspace

  1. Open Roblox Studio and load the Baseplate template.
  2. Close extra panels. The only ones you need open are:
    • Explorer
    • Properties (found in the “View” tab at the top).

Step 2: Create Plots

  1. Insert a Part (from the Home tab).
  2. Resize it in the Properties panel to: 100 x 1 x 100 This will be your plot size.
  3. Move it away from spawn points.
  4. Rename the part to Plot.
  5. Make sure:
    • Anchored is checked.
    • CanCollide is checked.

You now have your first player plot!

  1. Duplicate the plot (Ctrl + D on Windows or Cmd + D on Mac) until you have as many as you want. (In the tutorial, 8 plots were made.)
  2. In Explorer, select all your plots → right-click → Group as Folder.
  3. Rename the folder to Plots.

Step 3: Write the Plot Assignment Script

  1. In Explorer, go to ServerScriptService.
  2. Insert a new Script and rename it PlotHandler.
  3. Add the following code:
-- Reference the Plots folder
local plots = game.Workspace.Plots

-- When a player joins
game.Players.PlayerAdded:Connect(function(player)
    for _, plot in pairs(plots:GetChildren()) do
        if plot:GetAttribute("Taken") then
            continue -- Skip if already taken
        end

        -- Mark plot as taken and assign owner
        plot:SetAttribute("Taken", true)
        plot:SetAttribute("Owner", player.UserId)

        print("Plot has been given to " .. player.Name .. "!")

        break -- Stop after assigning one plot
    end
end)

-- When a player leaves
game.Players.PlayerRemoving:Connect(function(player)
    for _, plot in pairs(plots:GetChildren()) do
        if not plot:GetAttribute("Owner") then
            continue
        end

        if plot:GetAttribute("Owner") ~= player.UserId then
            continue
        end

        -- Free up the plot
        plot:SetAttribute("Taken", nil)
        plot:SetAttribute("Owner", nil)

        print("Plot has been removed from " .. player.Name)

        break -- Stop after resetting this plot
    end
end)

Step 4: Test the Script

  1. Click Play in Roblox Studio.
  2. Check the Output window:
    • You should see: Plot has been given to [YourUsername]!
    • Only one plot should be assigned (not all of them).
  3. In the Explorer, look at your plot’s Attributes:
    • Taken = true
    • Owner = [Your User ID]

Other plots should remain unassigned.


What’s Next?

You’ve now created a working plot assignment system! When players join, they automatically get a unique plot. When they leave, their plot is freed up for someone else.

In the next step of building your Tycoon, you’ll add:

  • Buttons for purchasing upgrades
  • Droppers and income systems
  • Tycoon progression logic
