Move a object and then return , like loop

Question

Hi Guys, I was wondering how can i move an enemy to the left and to the right in a short space, like an infinite loop.

I'm trying to think in a good method, but all that i've got until now is this

 void Move()
     {
         time= Time.deltaTime;
         if (time<= timePosition) 
         {
             transform.Translate(-speed*Time.deltaTime,0,0);
         }
         if (time > timePosition) 
         {
             transform.Translate(speed*Time.deltaTime,0,0);
         }
         
     }

basically it's a repeated movement applied in the update.

I maybe late but I would recommend using a coroutine rather than Update. Then by doing something like this....

 IEnumerator Move(){
      bool goingLeft = true;
      transform.Translate(-speed*Time.deltaTime,0,0); 
      while(true) {
           yield return new WaitforSevonds(timePosition);
           goingLeft ? transform.Translate(speed*Time.deltaTime,0,0) : transform.Translate(speed*Time.deltaTime,0,0);
           goingLeft ? false; true;
      }
 }

Thanks for the answer, I've studied my code and did it again. Now it is working like i wanted.

 public float walkSpeed = 1.0f;      // Walkspeed
     public float wallLeft = 0.0f;       // Define wallLeft
     public float wallRight = 5.0f;      // Define wallRight
     float walkingDirection = 1.0f;
     Vector2 walkAmount;
     float originalX; // Original float value
 
     private bool olhandoDireita = true;
     
     
     void Start () {
         this.originalX = this.transform.position.x;
     }
     
     // Update is called once per frame
     void Update () {
         walkAmount.x = walkingDirection * walkSpeed * Time.deltaTime;
         if (walkingDirection > 0.0f && transform.position.x >= originalX + wallRight) {
             walkingDirection = -1.0f;
             Flip();
         } else if (walkingDirection < 0.0f && transform.position.x <= originalX - wallLeft) {
             walkingDirection = 1.0f;
             Flip();
         }
         transform.Translate(walkAmount);
     }

You do this in a single line using Mathf.PingPong.

 void Update() {
     transform.position = new Vector3(Mathf.PingPong(Time.time, 3), transform.position.y, transform.position.z);
 }
