  <p>How to Implement real measures in it?</p>
  
  <p>I want to implement a real measures in Unity. how to do it?</p>
  
  
  
  <pre class="lang-csharp prettyprint-override"><code>public Vector2 GetAsMeters (Vector2 vec) {
      Vector2 meters = new Vector2 (0, 0);
      while (vec.x &gt; 1000) {
          vec.x -= 1000;
          meters.x++;
      }
      meters.x += vec.x;
      while (vec.y &gt; 1000) {
          vec.y -= 1000;
          meters.y++;
      }
      meters.y += vec.y;
      return meters;
  }
  </code></pre>
  
  <p><strong>EDIT</strong>: How to implement a measurement like "Left 4 Dead"? (this game has a huge map and its as long as real kilometers)</p>
