So i tried and i get this error saying :
PlayerPoints requires beta access and idk whats wrong...
PointsService = game:GetService("PointsService") script.Parent.MouseButton1Down:connect(function() game:GetService("PointsService"):AwardPoints(22745426, 7200) end)
This will help: http://wiki.roblox.com/index.php?title=Player_Points
And notice that you must have Player Points to award them to players, meaning that if you have no Player Points then you can't award any Player Point to players in your game.
MouseButton1Down or Click? You choose, Problem 1 declared
Problem 2: In line 6, that's not an id... I'll show you the correct script.
script.Parent.MouseButton1Click:connect(function(player)--Creates the function, and calls the clicker (Player) game:GetService("PointsService"):AwardPoints(player.userId, 7200) --Gives the player 7200 points... if there are 7200 points available... end)--Ends the function
The output basically means that you can't do it on Studio, you must go on a live server.
