Hey Folks - I have a non-document class that I want to put in charge of changing scenes when some conditions are met.

First things first, I need to figure out how to change scenes!

Here’s my code:

```auto
package classes {
    
    import flash.display.MovieClip;
    import flash.display.Stage;
    
    public class SceneMaster extends MovieClip {
        
        public function SceneMaster(stg:Stage):void {
            
            trace("done", stg)
            gotoAndPlay(1, "Lobby");
        }
    }
}

```

Here’s the error I’m getting:

ArgumentError: Error #2108: Scene Lobby was not found.  
at flash.display::MovieClip/gotoAndPlay()  
at classes::SceneMaster()  
at GameMaster()

I’ve tried accessing it like this

```auto
stg.gotoAndPlay(1, "Lobby");

```

but I get this error:

1061: Call to a possibly undefined method gotoAndPlay through a reference with static type flash.display:Stage.

Anyone have any ideas on how to do this?
