How to Create a Roblox Tycoon (Part 4: Droppers & Conveyors)

Now that we have buttons, prices, and cash in place, it’s time to make our Tycoon actually generate money! In this part, we’ll set up a dropper and conveyor system so players can earn income. Link to Part 3


Step 1: Add a Dropper Model

  1. Open the Toolbox and search for a dropper model.
    • Be careful! Many toolbox models include unsafe scripts.
    • Once inserted, open the Explorer and expand the dropper model.
    • Delete any scripts or unnecessary objects (fire, sparkles, etc.).
    • Keep only Parts.

Alternatively, you can build your own dropper from scratch.

  1. Place the dropper onto your plot and rename it to: Dropper

Step 2: Build a Conveyor

  1. Insert a Part and scale it into a flat rectangle for the conveyor belt.
  2. Duplicate side walls using Ctrl + D (or Cmd + D on Mac) so pieces don’t fall off.
  3. Group everything into a model named: Conveyor
  4. Make sure Anchored is checked for all parts.

Step 3: Make the Conveyor Move

  1. Select the main belt part (the moving surface).
  2. Rename it to: Belt
  3. Insert a Script inside the Belt, name it BeltScript, and add:
-- BeltScript
-- Makes parts slide across the conveyor

script.Parent.Velocity = Vector3.new(0, 0, 10) -- adjust axis/speed if needed


Press Run and drop a part on the conveyor. It should move along the belt.

Step 4: Set Up a Dropper Script

We want the dropper to spawn parts (the items players collect for money).

  1. Create a template part:
    • Insert a small block, color it however you want (e.g. Neon Blue).
    • Rename it: DropperTemplate
    • Move it into ServerStorage.
  2. Insert a Script into the Dropper, name it DropperScript, and add:
-- DropperScript

local template = game.ServerStorage:WaitForChild("DropperTemplate")

while task.wait(2) do
    local newDrop = template:Clone()
    newDrop.CFrame = script.Parent.Drop.CFrame * CFrame.new(0, -2, 0) -- spawn slightly below drop point
    newDrop.Parent = script.Parent:WaitForChild("DropperParts")

    -- Tag this as a droppable item
    newDrop:SetAttribute("DropPart", true)

    -- Cash value per drop (comes from dropper attribute)
    newDrop:SetAttribute("CashToGive", script.Parent:GetAttribute("CashPerDrop"))
end
  1. In the Dropper’s Properties → Attributes, add:
    • Name = CashPerDrop
    • Type = Number
    • Example Value = 2

Now the dropper will generate parts worth 2 Cash each.


Step 5: Add a Collector

This is where dropped parts are converted into money.

  1. Duplicate one of your conveyor parts.
  2. Move it to the end as a Collector Zone.
  3. Rename it: Collector
  4. Insert a Script, name it CollectorScript, and add:
-- CollectorScript
-- Awards cash when drop parts touch the collector

script.Parent.Touched:Connect(function(hit)
    if hit:GetAttribute("CashToGive") then
        -- Find owning plot
        local plot = script.Parent.Parent.Parent
        if not plot or not plot:GetAttribute("OwnerUserId") then return end

        local player = game.Players:GetPlayerByUserId(plot:GetAttribute("OwnerUserId"))
        if not player or not player:FindFirstChild("leaderstats") then return end

        -- Award cash
        player.leaderstats.Cash.Value += hit:GetAttribute("CashToGive")

        -- Remove collected part
        hit:Destroy()
    end
end)

Step 6: Enable Scripts When Purchased

Since droppers and conveyors are bought with buttons, we don’t want their scripts running before they’re unlocked.

  • Set all scripts (BeltScript, DropperScript, CollectorScript) to Disabled = true.
  • In your PlotHandler, when cloning unlocked items, enable their scripts:
for _, obj in ipairs(itemClone:GetDescendants()) do
    if obj:IsA("BaseScript") then
        obj.Enabled = true
    end
end

Step 7: Test the System

  1. Buy the Conveyor button → belt starts moving.
  2. Buy the Dropper button → parts drop every 2 seconds.
  3. Dropped parts hit the Collector → your Cash increases by 2.

Recap

  • Built a dropper and conveyor system.
  • Used templates to spawn drop parts.
  • Created a Collector that awards Cash.
  • Ensured scripts only run after purchase.

Next Step

Your Tycoon now generates money! Next, we’ll add data saving so player progress (cash & purchases) is saved between sessions.
