AS2 笔记 1——attachMovie 添加库影片

this["container"].attachMovie("useLoad", "useLoadMc", this.getNextHighestDepth());

attachMovie 不等于直接赋值，而是将库链接"useLoad"影片命名为"useLoadMc"，并添加到this["container"]容器中；

所以 remove(this["container"]["useLoadMc"])，仅仅删除被添加到容器this["container"]的useLoadMc影片剪辑

/**
	 * 删除非自身的影片
	 * @param	_mc
	 */
	public function removeAllIn(_mc:Object):Void
	{
		var m:MovieClip;
		for (var i in _mc)
		{
			m = _mc[i];
			if ((m != _mc))
			{
				remove(m);
			}
		}
	}

	/**
	 * 删除自身影片
	 * @param	_mc
	 */
	public function remove(_mc:MovieClip):Void
	{
		_mc.getDepth() < 0 ? _mc.swapDepths(_mc._parent.getNextHighestDepth()):0;
		_mc.removeMovieClip();
		_mc.unloadMovie();
		_mc = null;
	}
