Options in Main menu

Hi everybody , i would like to create an Options button in my main menu wich can modify my GameObjects preferences, for exemple modify the intensity of my point light , sounds volumes etc … Can somebody please tell me how to do that if it’s even possible on Unity , thnx .

One way to do this is to have an empty game object to which you attach a script that will hold all the values from your settings menu. There is literally a line of code to make your game object persist from one scene to another. (i forget what it is)

Thnx for replying "LostBalloon"but can you please, if possible, explain more how can i do this !! Again thnx a lot …
