Sorry but there is no such thing as an undetected Hack or Script. What I used to do when I was an intermediate Hacker is ask my mother and father to play Garry's Modification with me so we can build a better relationship and have fun. They would control the movement keys and I would control the mouse! It is really fun!
Though, as I've gotten older my parents don't like doing this with me anymore. They became grumpy and often yell rude things at me
. If you're around 14 to 18 years old then go and ask your parents to play some cool games with you!
