Error using removeChild (AS3)

Question

I am creating a pacman-style game. I am trying to remove an instance of a MovieClip using removeChild(). When the MovieClip instance \"box\" hits the MovieClip instance \"circle

Answer 1

if((ScoreObjects[0] as Circle)&&((ScoreObjects[0] as Circle).parent!=null))
{
   stage.removeChild(ScoreObjects[0]);
}

Answer 2

I don't have an AS3 compiler at hand to test this, but since you did stage.addChild(ScoreObjects[0]) I believe you should do stage.removeChild(ScoreObjects[0])?
