NEWBIE - how to make move like a mario brothers

Hello,

I'm new. Can someone help me write a script that my character can pass through the edges of the screen?

I write only script for teleport but i don;t need teleports.

 using UnityEngine;
 using System.Collections;
 
 
 public class teleport1 : MonoBehaviour {
     public Transform target;
 
     void OnTriggerEnter(Collider col){
         if (col.tag == "Player"){
             if (transform.position.x < 0)
                 col.gameObject.transform.position = new Vector3(transform.position.x+2.6f, transform.position.y-0.15f);
             else
                 col.gameObject.transform.position = new Vector3(transform.position.x-2.6f, transform.position.y-0.15f);
 
         }
 }
 }

I hope someone will help greetings
