How do you create a script that gives you in game points on click?

Hello! You should either use StringValue or NumberValues. First, if you already have a leader board then good. Otherwise, make sure you have one before posting a next step question.

Anyway here are some instructions;

1. Make sure you have your button 2, Make sure you have a local Script inside that button

if you have those steps done then we can start, in the local script type this code in;

local button = script.Parent -- The button
local Player = game.Players.LocalPlayer
local Currency = Player.leaderstats.Coins --Change this to where your currency is 

button.MouseButton1Down:Connect(function()
	Currency.Value = Currency.Value + 1 -- You can change 1 to how much they get
end)

This is a very basic script as well, I hope you learn some basics before asking a simple question. Questions like these may be moderated. But anyway I hoped I helped and if I did then please accept answer ;)
