title: Why is Vector3 non-invocable here and what can I do instead?
body: <p>In Unity I'm trying to update a y coordinate like this:</p>
  
  <pre><code>if (ballPos.position.y &gt; aiPos.position.y)
      {
          transform.position += Vector3 (0.0f, 1.0f, 0f);
      }
  </code></pre>
  
  <p>I'm getting the error that <code>Vector3</code> is a non-invocable method what can I do to change the position effectively? </p>
