Hi all,

I’m new to ActionScript 3 (had _some_ experience with ActionScript 2) and I was just wondering where addChild comes from?

Is it pre-built in or does it com from importing Flash.display.Sprite (and if it is from Flash.display.Sprite, does it mean it gets imported whenever you display _any_ subpackage of Flash.display?)
