fps player controller using rigidbody without character controller?

Question

Edit:I think the question might have been misunderstood so this is just to clarify. I have a gameobject which is followed by my main camera. I can look around with my mouse but cannot move in the direction my mouse is facing(fps game) Any help will be very useful. Found the answer..

 public Transform plr,cmr;
 public Rigidbody rb;
 public float xclamp=0f,speed=0f,mousespd=0f;
 void Update(){
 x = Input.GetAxis("Horizontal") * speed;
 y = Input.GetAxis("Vertical") * speed;
 Vector3  mov = new Vector3(x, 0f, y);
 mov = transform.TransformDirection(mov);
 rb.AddForce(mov);
 
 float mousex = Input.GetAxis("Mouse X") * mousespd;
 float mousey = Input.GetAxis("Mouse Y") * mousespd;
 
 xclamp -= mousey;
 
  Vector3 rotplr = plr.transform.rotation.eulerAngles;
  Vector3 rotcmr = cmr.transform.rotation.eulerAngles;
 
  rotcmr.x -= mousey;
  rotcmr.z = 0;
  rotplr.y += mousex;
 
  if (xclamp > 90)
 {
           xclamp = 90;
           rotcmr.x = 90;
  }
 else if (xclamp < -90f)
 {
        xclamp = -90;
        rotcmr.x = 270;
  }
 cmr.rotation = Quaternion.Euler(rotcmr);
 plr.rotation = Quaternion.Euler(rotplr);
 }

Hello @JustAbhi Something like this should work:

 //your player and camera gameObjects
 public GameObject player;
 public GameObject camera;
 
 //Mouse input will be stored in x and y. Rotation speed (kind of sesitivity) 
 //is stored in speed, public, so you can change it in the inspector.
 //By default it will be null (zero), so it will not work until you change it.
 float x;
 float y;
 public float speed;
 
 void Update()
 {
 //Read mouse input values.
  x = Input.GetAxis("Mouse X");
  y = Input.GetAxis("Mouse Y");
 
 //Rotate the player right and left
 player.transform.Rotate(0, x * speed, 0);
 
 //Look up and down only with your camera
 camera.transform.Rotate(y * speed, 0, 0);
 }

Sorry, something like this should work:

 public GameObject player;
 
 public float speed;
 
 void Update()
 {
  if(Input.GetKey(KeyCode.W))
 {
  player.GetComponent<Rigidbody>().AddForce(player.transform.forward * 
  speed, Force$$anonymous$$ode.VelocityChange);
 }

  if(Input.GetKey(KeyCode.A))
 {
  player.GetComponent<Rigidbody>().AddForce(-player.transform.forward * 
  speed, Force$$anonymous$$ode.VelocityChange);
 }

 if(Input.GetKey(KeyCode.D))
 {
  player.GetComponent<Rigidbody>().AddForce(player.transform.right * 
  speed, Force$$anonymous$$ode.VelocityChange);
 }

 if(Input.GetKey(KeyCode.A))
 {
  player.GetComponent<Rigidbody>().AddForce(-player.transform.right * 
  speed, Force$$anonymous$$ode.VelocityChange);
 }
 }
