As3 Help!

[MasterExploader]

im trying to convert myself from AS2 to as3 .. and well im trying to make games ,but man,its haveing strange problems that I dont get :(
i wrote this:

this.addEventListener(Event.ENTER_FRAME, movesE);
function movesE(event:Event):void
{
	if (name != "enemy")
	{
		if(root.Yattack.hitTestObject(this))
		{
			removeChild(this);
		}
		if (y < 239)
		{
			y++;
		}
		if (y > 239)
		{
			y--;
		}
	}
}

root.Yattack,is the attack sprite of the main dude(dont ask why its like that)..and it just doesnt work..
this is what flash says:

Symbol 'Enemy', Layer 'Layer 2', Frame 1, Line 7 1119: Access of possibly undefined property Yattack through a reference with static type flash.display:DisplayObject.

any idea on how to make it work?

the "root." isn't used in AS3 it is now MovieClip(root).

also I don't think "root." was the right syntax in AS2 either, I thought it was "_root." but I could be remembering wrong

wow cool,(and yeah in as2 its _root,but i thought since everything in as3 is like as2 just without the "_" so it might work :P)
also for some reason the removeChild(this) line doesnt work,while im running the game and hitting the enemy this is what showes up:

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display::DisplayObjectContainer/re moveChild()
at MyE/movesE()[MyE::frame1:9]

:S

I'm not positive about this because it's usually more complex than this but try putting MoiveClip(root). in front of removeChild(this)

Code properly, you're trying to turn AS3 into AS2, no point using AS3 if thats what you're going to do, set up a document class and shove your enemies in an array then test for your crap between the Player and them from a common parent instead of having your references all willy nilly.

it would be a start

The supplied DisplayObject must be a child of the caller.

parent.removeMoive(this)

Parent is the caller.
