How to stop multiple Movieclips at a time by play/pause button in AS3 - actionscript-3

Question

I have 4 Movieclips in timeline.these movieclips have inner animation. they are classically tween in timeline. I have to stop and play these four movieclips at a time by play/pause button. Noted that, I have used the following code for that purposes.
It can stop only one MovieClip which is in the upper layer, and the rest 3 Movieclips can't be stopped by play/ pause button. (I have tried all movie clips are in same instance name and also tried with different instance).
Here is my code:
import flash.events.MouseEvent;
var Playing: Boolean = false;
var lastPosition: Number = 0;
play_btn.addEventListener(MouseEvent.CLICK, onPlayClick);
pause_btn.addEventListener(MouseEvent.CLICK, onPauseClick);
function onPlayClick(event: MouseEvent):void {
if (Playing == false) {
Playing = true;
first_sl.play();
this.play();
}
}
function onPauseClick(event: MouseEvent):void {
Playing = false;
lastPosition = this.position;
first_sl.stop();
this.stop();
}

You can try like when you are stopping main timeline with stage.stop(); also use mc.stop(); ect. and when u play them use stage.play(); also mc.play();
import flash.events.MouseEvent;
var Playing: Boolean = false;
var lastPosition: Number = 0;
play_btn.addEventListener(MouseEvent.CLICK, onPlayClick);
pause_btn.addEventListener(MouseEvent.CLICK, onPauseClick);
function onPlayClick(event: MouseEvent):void {
if (Playing == false) {
Playing = true;
mc.play();
mc2.play();// other 2 mc's too
stage.play();
}
}
function onPauseClick(event: MouseEvent):void {
Playing = false;
lastPosition = this.position;
mc.stop();
mc2.stop(); // other mc's
stage.stop();
}
And if you are using last position for timeline also use it for mc's so it will be sync..
hope this on help tho :)

To stop the main timeline you can use stop() or MovieClip(root).stop() and to play it again, you can use play() or MovieClip(root).play() :
var playing: Boolean = false;
btn_play.addEventListener(MouseEvent.CLICK, onPlayClick);
btn_pause.addEventListener(MouseEvent.CLICK, onPauseClick);
function onPlayClick(event: MouseEvent):void
{
if (!playing) {
play(); // you can also use : MovieClip(root).play();
mc1.play();
mc2.play();
mc3.play();
mc4.play();
playing = true;
}
}
function onPauseClick(event: MouseEvent):void
{
if (playing) {
stop(); // you can also use : MovieClip(root).stop();
mc1.stop();
mc2.stop();
mc3.stop();
mc4.stop();
playing = false;
}
}
Hope that can help.
