  <p>i get this error:</p>
  <p>Assets\Scripts\OblstacleMove.cs(30,13): error CS7036: There is no argument given that corresponds to the required formal parameter 'collision' of 'OblstacleMove.CambioDireccion(Collision)'</p>
  <p>i tryed</p>
  <pre><code>if(gameObject.tag == &quot;Cube&quot;)
          {
              transform.Translate(new Vector2(velocidad * Time.deltaTime, 0));

          }
  </code></pre>
  <p>and it didnt work, i also tryed</p>
  <pre><code>    private void ChangeDirection(Collision collision)
      {
          if(collision.gameObject.tag == &quot;MapLimit&quot;)
          {
              velocidad = velocidad * -1;
          }
      }
  </code></pre>
  <p>i dont know what else to try</p>
