Character Controller Movement With WASD

i Have Been Looking For Character Controllers That Use WASD For Movement Instead Of An Axis, And Can Not Find One I Need One Pretty Much Like This One

 using UnityEngine;
 using System.Collections;
 
 public class ScurgeofShadowsController : MonoBehaviour {
     public float speed = 6.0F;
     public float jumpSpeed = 8.0F;
     public float gravity = 20.0F;
     private Vector3 moveDirection = Vector3.zero;
     void Update() {
         if(CombatSystemScurge.PublicHealth <= 10) {
             speed = 1.5f;
         }
         CharacterController controller = GetComponent<CharacterController>();
         if (controller.isGrounded) {
             moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
             moveDirection = transform.TransformDirection(moveDirection);
             moveDirection *= speed;
             if (Input.GetButton("Jump")) {
                 moveDirection.y = jumpSpeed;
             }    
         }
         moveDirection.y -= gravity * Time.deltaTime;
         controller.Move(moveDirection * Time.deltaTime);
     }
 }

But Uses WASD. Thanks!
