Simple FPS Camera

Hi there!

Today I just want to share my Simple FPS Camera
to anyone who want to movement to looking something.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class FPSCamera : MonoBehaviour
6. {
7.     [Range(0.1f, 100)] [SerializeField] float Speed = 20f;
8.     [Range(0.1f, 9f)] [SerializeField] float Sensitivity = 2f;
9.     [Range(0f, 90f)] [SerializeField] float UpLimit = 90f;
10.  
11.     private Vector2 rotation = Vector2.zero;
12.     const string xAxis = "Mouse X";
13.     const string yAxis = "Mouse Y";
14.  
15.     void Update()
16.     {
17.         // Lock cursor at center of screen
18.         Cursor.lockState = CursorLockMode.Locked;
19.  
20.         // looking roation by mouse
21.         rotation.x += Input.GetAxis(xAxis) * Sensitivity;
22.         rotation.y += Input.GetAxis(yAxis) * Sensitivity;
23.         rotation.y = Mathf.Clamp(rotation.y, -UpLimit, UpLimit);
24.         var xQuat = Quaternion.AngleAxis(rotation.x, Vector3.up);
25.         var yQuat = Quaternion.AngleAxis(rotation.y, Vector3.left);
26.         transform.localRotation = xQuat * yQuat;
27.  
28.         // movement by W A S D
29.         Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
30.         this.transform.position += this.transform.forward * movement.z * movement.magnitude * Time.deltaTime * Speed;
31.         this.transform.position += this.transform.right * movement.x * movement.magnitude * Time.deltaTime * Speed;
32.     }
33. }
34.  

I hope it will be useful for you!
