title: Unity3d - Load a specific scene on play mode
body: <p>Ok, so I'm working on a small project that has a main menu and 10 levels. From time to time I edit different levels, and want to try them out, however I get a <code>NullPointerException</code> as my levels rely on certain variables from the main menu for the levels to work, which means I have to alter my levels, then load my main menu and play from there.</p>
  
  <p>Is there something that can be done in the Unity Editor to default load a specific scene when you hit Play, and not the scene you're on?</p>
  
  <p>I could obviously resolve this to something like </p>
  
  <pre><code>public bool goToMenu; //set this to true in my levels through inspector
  
  Start()
  {
      if (goToMenu)
          //then load main menu
  }
  </code></pre>
  
  <p>but it would be really handy if there was a way to set the default level to load when hitting play mode. I've had a look in Preferences but couldn't find anything.</p>
  
  <p>Thanks!</p>
