I have this script and I need to make it so that the mouse can rotate 360 degrees horizontally around the object if you move your mouse that way and that the new way your facing becomes forward so when you press w it will go that way.
using UnityEngine;
using System.Collections;
public class Camera_Controller : MonoBehaviour {
public GameObject player;
private Vector3 offset;
void Start ()
{
offset = transform.position;
}
void LateUpdate ()
{
transform.position = player.transform.position + offset;
}
}
In the Standard Assets, there are the two scripts you need: “MouseLook” and “FPSInputController”. I attached them for convenience. Also, not all of the code is actually necessary, but it all works pretty well. If you need help modifying it to suit specific needs, feel free to ask.
Also, if this solved your problem completely, please say so. I get awfully curious if I succeeded or not. 
MouseLook:
using UnityEngine;
using System.Collections;
/// MouseLook rotates the transform based on the mouse delta.
/// Minimum and Maximum values can be used to constrain the possible rotation
/// To make an FPS style character:
/// - Create a capsule.
/// - Add the MouseLook script to the capsule.
/// -> Set the mouse look to use LookX. (You want to only turn character but not tilt it)
/// - Add FPSInputController script to the capsule
/// -> A CharacterMotor and a CharacterController component will be automatically added.
/// - Create a camera. Make the camera a child of the capsule. Reset it's transform.
/// - Add a MouseLook script to the camera.
/// -> Set the mouse look to use LookY. (You want the camera to tilt up and down like a head. The character already turns.)

}
}

{
// Make the rigid body not change rotation
if (rigidbody)
rigidbody.freezeRotation = true;
}
}]
FPSInputController:
private var motor : CharacterMotor;
// Use this for initialization
function Awake () {
motor = GetComponent(CharacterMotor);
}
// Update is called once per frame
function Update () {
// Get the input vector from kayboard or analog stick
var directionVector = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
if (directionVector != Vector3.zero) {
// Get the length of the directon vector and then normalize it
// Dividing by the length is cheaper than normalizing when we already have the length anyway
var directionLength = directionVector.magnitude;
directionVector = directionVector / directionLength;
// Make sure the length is no bigger than 1
directionLength = Mathf.Min(1, directionLength);
// Make the input vector more sensitive towards the extremes and less sensitive in the middle
// This makes it easier to control slow speeds when using analog sticks
directionLength = directionLength * directionLength;
// Multiply the normalized direction vector by the modified length
directionVector = directionVector * directionLength;
}
// Apply the direction to the CharacterMotor
motor.inputMoveDirection = transform.rotation * directionVector;
motor.inputJump = Input.GetButton("Jump");
}
// Require a character controller to be attached to the same game object
@script RequireComponent (CharacterMotor)
@script AddComponentMenu ("Character/FPS Input Controller")
Not to take away from MDragon’s answer, but have a look at the SmoothMouseLook script, it works much better then the one in Standard Assets (personal opinion)

Will these work for a none fps?
Yeah. I was following a Unity-based book that modifies these scripts for a first-person adventure game, and these work quite well. Use and modify as you please to solve any issue at hand.
Edit: Slideaekar, thanks for sharing that script. It looks really nice and looks like quite a bit of time was spent to add the math for the smooth effect. Do you know if you still need the FPSInputController as well as all the other instructions?
Also, NutellaDaddy, the SmoothFollow may seem more complicated, but it shouldn’t be much harder to change to your needs. When editing scripts with lots of math like these, I tend to just section off what’s necessary and never touch those areas if I don’t understand them well enough and then touch them a little if I finally feel confident. Hope they work well.
No you don’t need the FPSInputController for this to work, I am currently using it on my project (just temporarily for the moment) and it works quite well for me. In my project you have the ability to switch between 1st and 3rd person view. But I did modify it slightly to rotate the transform on the x axis and the camera on the y axis.
I’ve already modified it for my purpose. Thanks to both of you!
