Trouble with touches

Hello, I have been trying to get touches to work for quite a while now, but I don’t know how to do it. What I want to do is I make a menu with a functional button and when I press it it switches to the game. I would also like to add touch controls for a Sprite. Any help would be greatly appreciated.
