How to make an object move endlessly?

December 15, 2022

I want to move an object from position A to position B on X axis endlessly. But it does move and comeback only once. How to make it continuosly? I’ve tried Vector3.Lerp or just creating new Vector3 but it only teleports.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MovingTarget : MonoBehaviour
{
    [SerializeField] private Vector3 firstPosition = new Vector3(-14f, 2.5f, 17f);
    [SerializeField] private Vector3 secondPosition = new Vector3(14f, 2.5f, 17f);
    
   
    public float speed = 10f;
  

    void Start()
    {
       transform.position = firstPosition;
    }
    
    void Update()
    {

      

      
            transform.position = Vector3.MoveTowards(transform.position, secondPosition, Time.deltaTime * speed);
       
        if(transform.position == secondPosition)
        {
            secondPosition = firstPosition;
        }

       



    }
}

>Solution :

I don’t use Unity, but since nobody else answered….

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MovingTarget : MonoBehaviour
{
    [SerializeField] private Vector3 firstPosition = new Vector3(-14f, 2.5f, 17f);
    [SerializeField] private Vector3 secondPosition = new Vector3(14f, 2.5f, 17f);
    private Vector3 target;

    public float speed = 10f;

    void Start()
    {
       transform.position = firstPosition;
       target = secondPosition;
    }
    
    void Update()
    {
        transform.position = Vector3.MoveTowards(transform.position, target, Time.deltaTime * speed);
       
        if (transform.position == firstPosition)
        {
            target = secondPosition;
        }
        else if (transform.position == secondPosition)
        {
            target = firstPosition;
        }
    }
}
