Unity fps rotation camera

Question

In my game I have a camera and I want to have an FPS like rotation attached to this camera.

So if I move my cursor to the left, I want my cam to rotate to the left. If I

Answer 1

Simple Script, Not Sure it will work with you, might as well give it a try

using System.Collections;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Security.Cryptography;
using System.Threading;
using UnityEngine;

public class mouse_lookat : MonoBehaviour
{
    public float mouseSensitivity = 100f;

    public Transform playerBody;

    float xRotation = 0f;

    // Start is called before the first frame update
    void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
    }

    // Update is called once per frame
    void Update()
    {
        float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
        float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
        playerBody.Rotate(Vector3.up * mouseX);
    }
}

i created 2 scripts for my FPS project that work flawlessly for my movement (currently havnt added jump mechanics) and it seems like youve overcomplicated alot of things that can be quite simple and straight forward. im also new to coding so please correct me if im wrong heres my code

// this is in the player script which i put on an empty parent object of the camera and player sprite

public class player : MonoBehaviour
{
    [Header("player Movement")]
    [SerializeField] float moveSpeed = 5f;
    [SerializeField] public float mouseSensitivity = 5f;

    
    Rigidbody rigidBody;
   
    // Use this for initialization
    void Start()
    {
        
    }

 void Update()
    {
        Move();
       
    }


    private void Move()
    {
        transform.Translate(Vector3.forward * Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime);
        transform.Translate(Vector3.right * Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime);
        transform.Rotate(Vector3.up * Input.GetAxis("Mouse X") * mouseSensitivity);
    }

//this is the camera movement script which i put on the camera(will also use this script to add a function to change from 1st person to 3rd person for certain abilities)

{

    player player;
    // Use this for initialization
    void Start()
    {
        player = FindObjectOfType<player>();
    }

    // Update is called once per frame
    void Update()
    {
        MoveView();
    }
    private void MoveView()
    {
        transform.Rotate(Vector3.left * Input.GetAxis("Mouse Y") * player.mouseSensitivity);
    }
}

Answer 3

I just found my answer in this topic:

http://forum.unity3d.com/threads/109250-Looking-with-the-Mouse?highlight=person+camera

---

The code from that topic:

C# Mono code:

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.)
[AddComponentMenu("Camera-Control/Mouse Look")]
public class MouseLook : MonoBehaviour {

    public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
    public RotationAxes axes = RotationAxes.MouseXAndY;
    public float sensitivityX = 15F;
    public float sensitivityY = 15F;

    public float minimumX = -360F;
    public float maximumX = 360F;

    public float minimumY = -60F;
    public float maximumY = 60F;

    float rotationY = 0F;

    void Update ()
    {
        if (axes == RotationAxes.MouseXAndY)
        {
            float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX;

            rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
            rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);

            transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0);
        }
        else if (axes == RotationAxes.MouseX)
        {
            transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0);
        }
        else
        {
            rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
            rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);

            transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0);
        }
    }

    void Start ()
    {
    //if(!networkView.isMine)
        //enabled = false;

        // Make the rigid body not change rotation
        //if (rigidbody)
            //rigidbody.freezeRotation = true;
    }
