,Third Person Movement Script Help

Hello everyone! I have been trying to get this to work for three days banging my head against the wall :( I have gotten it to work for the most part by piecing other people scripts and tutorials together. I would like my character to rotate in place when stationary and pressing any button on the horizontal axis. Also when I run forward and press horizontal axis would like character to gradually turn while running. Except if the rightmouse button is held down then strafe left and right if pressing the horizontal axis. This probably is confusing and I can draw it out if need be. Below is my current code and if anyone has a suggestion to get ride of the nasty if statement "if(horizontal != 0 || vertical != 0)" on line 72 that would be awesome. Thanks in advance for any help I appreciate it. I am also using cinemachine free look camera to control the camera for the player set to heading target forward and orbit world space. playermovementscript.cs
