I want to make a GUI open a Help GUI., and if it is clicked again to close it. I don't know how to do the second part.
This piece of code stores a boolean value of whether the Help GUI is open or not. When the button is clicked, it checks whether it is open or closed then changes the visibility accordingly:
local open = false local gui = TextButton -- Change this to the location of your open/close button local help = Frame -- Change this to the location of your help menu gui.MouseButton1Click:connect(function() if open == true then help.Visible = false open = false elseif open == false then help.Visible = true open = true end end)
