Character moving to mouse in third person camera

Hello, I want to make when I press W or UpArrow my character move to mouse, how i can do it?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 [RequireComponent(typeof(Rigidbody))]
 
 public class PlayerController : MonoBehaviour
 {
 
     private Rigidbody rigidBody;
     private Transform playerPosition;
 
     public float playerSpeed = 10f;
     public float playerJump = 10f;
 
     void Start()
     {
         rigidBody = GetComponent<Rigidbody>();
         playerPosition = GetComponent<Transform>();
     }
 
     void Update()
     {
         if (Physics.Raycast(playerPosition.position, Vector3.down, 1f) && Input.GetButtonDown("Jump"))
         {
             rigidBody.AddForce(Vector3.up * playerJump, ForceMode.Impulse);
         }
     }
 
     private void FixedUpdate()
     {
         Vector3 move = Vector3.zero;
         move.y = Input.GetAxis("Vertical");
         move.x = Input.GetAxis("Horizontal");
         float hitdist = 0.0f;
 
         rigidBody.AddForce(move.x,0,move.y * playerSpeed);
 
         Plane playerPlane = new Plane(Vector3.up, transform.position);
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 
         if (playerPlane.Raycast(ray, out hitdist))
         {
             Vector3 targetPoint = ray.GetPoint(hitdist);
             Quaternion targetRotation = Quaternion.LookRotation(targetPoint - transform.position);
             transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, playerSpeed * Time.deltaTime);
         }
 
     }
 }
