How to make object go from A to B and from B to A with same key

Question

Hello! Im trying to make my first game, and i need some help on how to make my object move from A to B when i press "a", and from B to A when i press "a" again. I have found a script that moves my object from A to B, but i can't figure out how to make it go from B to A when i press "a" again. alt text

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class lerp : MonoBehaviour { 
 
     public GameObject player;
 
     private Vector3 pos1;
     private Vector2 pos2;
 
     private float distance = 4.7f;
 
     private float time = 0.05f;
 
     private float currentTime = 0;
 
     private bool keyHit = false;
 
 
     // Use this for initialization
     void Start () {
         pos1 = player.transform.position;
         pos2 = player.transform.position + Vector3.right*distance;
     }
     
     // Update is called once per frame
     void Update () {
         if (Input.GetKeyDown ("a")) { keyHit = true; }
         if (keyHit == true)
         {
             currentTime += Time.deltaTime;
             if (currentTime >= time) { currentTime = time;
             }
             float Perc = currentTime / time;
             player.transform.position = Vector3.Lerp(pos1, pos2, Perc);
             }
     }
 }

Hi, you could add a variable to know in which position you are for example:

 int currentPos
 if (player.transform.position == pos1)
 {
 currentPos = 1;
 }
 else if (player.transform.position == pos2)
 {
 currentPos = 2;
 }
 else
 {
 currentPos = 0;
 }
 
 if (Input.GetKeyDown ("a")) {
 keyHit = true;
 }
          if (keyHit == true)
          {
              currentTime += Time.deltaTime;
              if (currentTime >= time)
              {
              currentTime = time;
              }
              float Perc = currentTime / time;
 
              if (currentPos == 1)
              {
              player.transform.position = Vector3.Lerp(pos1, pos2, Perc);
              }
              else if (currentPos == 2)
              {
              player.transform.position = Vector3.Lerp(pos2, pos1, Perc);
              }
              }
      }

Then you must probably set keyHit to false again when the player reached the Pos. Ask if you need more.

Hey @MT369MT! Thanks for the tips. How do i make the var know if the object is in pos1 or pos2? I'm very new at coding, just started a couple days ago :/

pos1 = -2,35 X , pos2 = 2,35 X

Create two new variables called pos1 and pos2. Assign them to pos1 = new Vector2(-2.35, 0) and pos2 = new Vector2(2.35, 0)
