Plz help

hey Im just coming and going here and Im making a game but I still need the scripts. I got down the walking forward, crouching, and jumping down, but when they go backwards, they dont turn around the other way, thay just walk backwards. Also, when I make an object jump, I want it to be able to jump and move forward in the air. It just teleports to the ground and slides forward. So can anyone help me?
