Roblox click detector script

Where to put it

Script — Inside the part (Workspace > Button > Script). It runs on the server, so players can't change what it does.

1. Insert an anchored Part, then insert a ClickDetector and a Script inside it.
2. For the coin reward, players need leaderstats > Coins — the leaderboard script creates it.

The script

local Players = game:GetService("Players")

local part = script.Parent
local detector = part:WaitForChild("ClickDetector")

local COOLDOWN = 1 -- seconds between clicks per player
local lastClick = {}

detector.MaxActivationDistance = 32

detector.MouseClick:Connect(function(player)
	local now = os.clock()
	if lastClick[player] and now - lastClick[player] < COOLDOWN then
		return
	end
	lastClick[player] = now

	local leaderstats = player:FindFirstChild("leaderstats")
	local coins = leaderstats and leaderstats:FindFirstChild("Coins")
	if coins then
		coins.Value += 1
	end
	part.Color = Color3.fromHSV(math.random(), 0.7, 1)
end)

Players.PlayerRemoving:Connect(function(player)
	lastClick[player] = nil
end)

How it works

• MouseClick fires on the server with the player who clicked. Taps on phones and tablets fire it too.
• The cooldown is checked on the server, so an auto-clicker can't earn more than one coin per second.
• MaxActivationDistance is how close (in studs) the player must be to click it.

Variations

local detector = script.Parent:WaitForChild("ClickDetector")
local lamp = workspace:WaitForChild("Lamp")
local light = lamp:WaitForChild("PointLight")

detector.MouseClick:Connect(function()
	light.Enabled = not light.Enabled
	lamp.Material = light.Enabled and Enum.Material.Neon or Enum.Material.SmoothPlastic
end)

local button = workspace:WaitForChild("Button")
local detector = button:WaitForChild("ClickDetector")

local highlight = Instance.new("Highlight")
highlight.FillTransparency = 1
highlight.Enabled = false
highlight.Parent = button

detector.MouseHoverEnter:Connect(function()
	highlight.Enabled = true
end)
detector.MouseHoverLeave:Connect(function()
	highlight.Enabled = false
end)

Common mistakes

• Giving rewards from a LocalScript: the change isn't saved on the server and exploiters can fire it. Reward in a server Script.
• Another part (often a transparent one) sits in front of the button and catches the click. Move it, or turn off its CanCollide and CanQuery.
• The player is too far away — the default range is 32 studs.
• No cooldown on rewards: auto-clickers will farm your currency.
