Let character moving towards it's facing?

I am new to Unity and I followed the survival shooter tutorial to make the player has a basic movement based on the horizontal and vertical axis also it is able to face towards the mouse location, but now I want to make the player moving towards it's facing ( for example if I hit "W", the character will move forward towards it's facing direction). Any suggestions and helps will be appreciated!

Here is my code:

 void FixedUpdate() {
         float h = Input.GetAxisRaw("Horizontal");
         float v = Input.GetAxisRaw("Vertical");
         Move(h, v);
         Turning();
         Animating(h, v);
     }
 
     void Move(float h, float v) {
         runKey = Input.GetKey(KeyCode.LeftShift);
         movement.Set(h, 0f, v);
         if (runKey) {
             //Debug.Log("Run!");            // Runkey test
             movementSpeed = 12f;
         }
         else {
             movementSpeed = 6f;
         }
         movement = movement.normalized * movementSpeed * Time.deltaTime;
         playerRigidbody.MovePosition(transform.position + movement);
        
     }
 
     void Turning() {
         Ray camRay = Camera.main.ScreenPointToRay(Input.mousePosition);
         RaycastHit floorHit;
         //Debug.Log(camRay);                // Camera postion debugging
         Debug.DrawRay(camRay.origin, camRay.direction * camRayLength, Color.green, 20);
         if (Physics.Raycast(camRay, out floorHit, camRayLength, floorMask)) {
             Vector3 playerToMouse = floorHit.point - transform.position;
             playerToMouse.y = 0f;
             //Debug.Log("AAA");             // Camera Raycast debugging
             Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
             playerRigidbody.MoveRotation(newRotation);
         }
     }
