How to make a currency script that adds the currency when a player touches a part?

so this is simple enough, you just need to add a value to the leaderstat. Hope this helps!

--put this code in the coin

amount = 1 --how much you get for touching it

function onTouched(part)
	local humanoid = part.Parent:FindFirstChild("Humanoid")
	if (humanoid~=nil) then
		local touch = game.Players:FindFirstChild(humanoid.Parent.Name)
		local leaderstats = touch:FindFirstChild("leaderstats")
		local points = leaderstats:FindFirstChild("Points") -- change "Points" with you own currency
		points.Value = points.Value + amount
	end
	script.Parent:Destroy() -- optional, I added this because I think you'll want to destroy the coin after touching it.
end

script.Parent.Touched:Connect(onTouched)
