Unusual movement script. Any ideas how to do that?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
  
 public class Move : MonoBehaviour
 {
     public float speed = 3f;
  
     private bool moving = false;
    
     public float zPos, xPos;
     public bool move = false;
     public SwipeManager swipe;
     private bool IsMoving = false;
     private Animator animator;
  
     // Start is called before the first frame update
     void Start()
     {
         xPos = ChangeXPos(1);
         zPos = ChangeZPos(1);
         animator = transform.GetChild(0).GetComponent<Animator>();
     }
  
  
     // Update is called once per frame
     void Update()
     {
         int swipeDir = swipe.GetSwipeDirection();
         Debug.Log(swipe.GetSwipeDirection());
         switch (swipeDir)
         {
             case 1:
                 animator.SetInteger("direction", 1);
                
                 break;
             case 2:
                 animator.SetInteger("direction", 2);
                 break;
             case 3:
                 animator.SetInteger("direction", 3);
                 break;
             case 4:
                 animator.SetInteger("direction", 4);
                 break;
             case 0:
                 animator.SetInteger("direction", 0);
                 break;
         }
      
        
  
        
        
      
     }
     bool  Step (Vector3 targetPosition)
     {
         bool success = false;
      
         transform.position = Vector3.MoveTowards(transform.position, targetPosition, speed * Time.deltaTime);
        
         if(transform.position == targetPosition)
         {
             success = true;
          
         }
         return success;
  
     }
     bool ZStep(float zPos)
     {
         bool complete = false;
         moving = true;
         if(Step(new Vector3(transform.position.x, transform.position.y, zPos)))
         {

         {

             moving = false;
         }
         return complete;
     }
     float ChangeZPos(int dir)
     {
        
         if(dir == 1)
         {
             return transform.position.z + 5f;
         } else
         {
             return transform.position.z - 5f;
         }
  
     }
     float ChangeXPos(int dir)
     {
         if(dir == 1)
         {
             return transform.position.x + 5f;
         } else
         {
             return transform.position.x - 5f;
         }
     }
     IEnumerator wait(float wait)
     {
         yield return new WaitForSeconds(wait);
     }
 }

Can someone please help me to make a script that dmoves the player for +5 or -5 by each coordinate when player inputs a swipe(1 - up, 2 - down, 3 - left, 4 - right, accesed by GetSwipeDirection() in Update()), so when player input for example 1 player must move to transform.position.z + 5f smoothly using moveTowards. And yep that's not even all. How to check when the player is moving up for example that if on the right or left there is nothing then stop. I am really stuck with that.
