title: My unity IEnumerator method not seems to be work
body: <p>I have some code: 
  Why Debug.Log inside the IEnumerator method not display anything?
  And why my method isn`t working?</p>
  
  <pre><code>void Update()
      {
          if (Input.GetKeyDown(KeyCode.G))
          {
              Debug.Log(true);
              MoveInsideTheShape(speedy);
          }
      }
  
      public IEnumerator MoveInsideTheShape(float speed)
      {
          speed = 1 / speed;
          float totalLenght = cam.orthographicSize * 2;
          float iterationLenght = totalLenght / speed;
  
          Debug.Log(cam.orthographicSize); // does not work
  }
  </code></pre>
