這是在keith peters的advanced as3 amimation 中讀到的關於array.sort()的用法
在這邊做個筆記以免忘記
假設今天有個array _items, 用來儲存3d物件
private function sortItems():void
{
_items.sort(depthSort);
for(var i:int = 0; i < _items.length; i++)
{
_holder.addChildAt(_items[i] as Sprite, i);
}
}
private function depthSort(objA:DisplayObject, objB:DisplayObject):int
{
var posA:Vector3D = objA.transform.matrix3D.position;
posA = _holder.transform.matrix3D.deltaTransformVector(posA);
var posB:Vector3D = objB.transform.matrix3D.position;
posB = _holder.transform.matrix3D.deltaTransformVector(posB);
return posB.z - posA.z;
}
you can create your own custom function to do the sorting. If you create ...

在使用describeType(root)時:
表示root是一個GETTER方法，而傳回的型別是DisplayObject。
DisplayObject並沒有"自定變數"的宣告。所以在編譯時root.自定變數 會發生錯誤。
然而使用root["自定變數"]時，由於編譯程式裡不會檢查，所以不會發生錯誤。
