How do I make a Obby for Cash? - Zednov's Tycoon Kit

Firstly, I would like to say that ScriptingHelpers is not a website for requesting scripts. Requesting scripts is against the guidelines of ScriptingHelpers. Anyways, on to actually making the script. In ServerScriptService, create a new script and name it "Leaderstats".

-- Leaderstats
game.Players.PlayerAdded:Connect(function(plr)
	local leaderstats = Instance.new("IntValue") -- Container for leaderboard values
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = plr

	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Value = 0
	cash.Parent = leaderstats
end)

That script will create a leaderboard. "leaderstats" is a container for values that are displayed on the leaderboard, and "Cash" will be the value displayed. Create a new script in ServerScriptService called "CashScript".

-- CashScript
local debounce = false -- Cooldown
local part = workspace.Part -- Change to the part you want to give cash
local cooldownTime = 1

part.Touched:Connect(function(hit)
	local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")
	if humanoid and not debounce then -- Checking to see if this is something alive and not on a cooldown
		local playerName = humanoid.Parent.Name -- Getting the name of the character
		local player = game.Players[playerName] -- Finding out if this is a player
		if player then
			player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + 10
			debounce = true -- Makes a cooldown
			wait(cooldownTime)
			debounce = false
		end
	end
end)

I hope this helped. Anyways, please refrain from requesting scripts.
