What I mean in my question is that how to make your player rotate automatically when I move my mouse left for example and my whole characters body will rotate and limit its rotation back to a 2D view.

Similar to the game "Rochard" if you guys know it. But I'm having trouble how to figure it out.

This is my Code:

#pragma strict



var spinx : int = 0;

var spiny : int = 0;

var spinz : int = 0;



function Update () {

    transform.Rotate(spinx, spiny, spinz);

}

this script should rotate your object acccording to mouse position

using UnityEngine;

using System.Collections;



     public class MouseLook : MonoBehaviour {



         void Update () {

            Vector3 mousePos = new Vector3(Input.mousePosition.x, Input.mousePosition.z, 10);

            Vector3 lookPos = Camera.main.ScreenToWorldPoint(mousePos);

            lookPos = lookPos - transform.position;

            float angle = Mathf.Atan2(lookPos.z, lookPos.x) * Mathf.Rad2Deg;

            transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);



         }

     }

You could import the standard player controls package from unity itself and edit the first person controller to your likings. This is what I tend to do when I want a control in my game that can do what you desire.

The following script should rotate your object according to mouse position,

 using UnityEngine;

 using System.Collections;



 public class RotateClass : MonoBehaviour {

     public float horizontalSpeed = 2.0F;

     public float verticalSpeed = 2.0F;

     void Update() {

         float h = horizontalSpeed * Input.GetAxis("Mouse X");

         float v = verticalSpeed * Input.GetAxis("Mouse Y");

         transform.Rotate(v, h, 0);

     }

 }

First, I am really sorry to write it in C#. But I hope it can help you. This script is attached to player gameobject.

private Vector3 MousePositionViewport = Vector3.zero;

private Quaternion DesiredRotation = new Quaternion();

private float RotationSpeed = 15;



void Update () {

    MousePositionViewport = Camera.main.ScreenToViewportPoint (Input.mousePosition);

    if (MousePositionViewport.x >= 0.6f) {

        DesiredRotation = Quaternion.Euler (0, 90, 0);

    } else if(MousePositionViewport.x < 0.6f && MousePositionViewport.x > 0.4f){

        DesiredRotation = Quaternion.Euler (0, 270, 0);

    }else {

        DesiredRotation = Quaternion.Euler (0, 180, 0);

    }

    transform.rotation = Quaternion.Lerp (transform.rotation, DesiredRotation, Time.deltaTime*RotationSpeed);

}
