如何使用as3同时访问所有动画片段（以及动画片段中的动画片段，......）？

Question

I am using Adobe Animate (or Adobe Flash Professional) and I often navigate timeline with as3. I want to reset all movieclips (and movieclips inside a moviclip) when the stage reach to an exact frame. like:

 if (this.currentFrame == 120) 
    { 
        allMovieClips.gotoAndPlay(1);
    } 

I am thinking about taking access to all movieclips in library but I don't know how. Is there any way to do that?

Answer 1

You cannot access things in Library as the Library is a design-time concept. If you want to reset all the MovieClip instances presently attached to the Stage, you do the following:

import flash.display.Sprite;
import flash.display.MovieClip;

// Start resetting them from the topmost timeline.
reset(root as Sprite);

function reset(target:Sprite):void
{
    // First, browse all the children of the target.
    for (var i:int = 0; i < target.numChildren; i++)
    {
        var aChild:Sprite = target.getChildAt(i) as Sprite;

        // If a child is a container then go recursive on it.
        if (aChild) reset(aChild);
    }

    // Second, if the target is not only the container
    // of other things but a MovieClip itself then rewind it.
    if  (target is MovieClip)
        (target as MovieClip).gotoAndPlay(1);
}
