Accessing Child MC

[ryrocks]

Hi everyone,
Simple question...I think!
I'm creating a platform game, I want the ball to stay in the middle of the page while the background moves when the user presses the arrow keys, it looks like the ball is moving, but it's not.

To do this I have the ball in one movieclip and everything else (ground mc, enemies mcs, items mcs etc) in a container mc. So all I need to do is move the container left and right when the arrow keys are pressed, I can do that, no problem.

The problem occurs when I try to access the movieclips inside the container movieclip, for doing hit tests and such. The instance names come back as undefined.

If my container movieclip is named 'container_mc' and the ground movieclip is inside this named 'ground_mc' how would I change the below code to run the hittest?

stage.addEventListener(Event.ENTER_FRAME, hitCheck);
function hitCheck(event:Event):void
{
if (ball_mc.hitTestObject(ground_mc))
{
ball_mc.y = ground_mc.y;
}
}

Thanks a lot,

Ryan

function hitCheck(event:Event):void
{
   if ( ball_mc.hitTestObject( container_mc.ground_mc ) )
   {
      ball_mc.y = ground_mc.y;
   }
}

Safe, Cheers, I knew it'd be easy, I started to try that but go put off by the coding assistant!
