how to pause multiple symbols with mouse click in flash AS3 - actionscript-3

Question

I have been using actionscript 3 to control my animations,
I can play and reset the video but not able to pause globally.
There are totally 3 symbols,
1st Parent movieclip
2nd child moviclip with animation--> I am able to pause this.
3rd child movieclip with animation--> I am unable to pause this
Script
package lib {
import flash.display.MovieClip;
import flash.events.*;
public class Controlstry extends MovieClip {
public function Controlstry() {
// constructor code
addEventListener(Event.ADDED_TO_STAGE,init);
}
private function init(evt=null)
{
if(video_mc != null)
{
playBtn.addEventListener(MouseEvent.MOUSE_DOWN, playVideo);
pauseBtn.addEventListener(MouseEvent.MOUSE_DOWN, pauseVideo);
replayBtn.addEventListener(MouseEvent.MOUSE_DOWN,replayVideo);
}
}
private function playVideo(evt:MouseEvent)
{
if(video_mc.currentFrame == video_mc.totalFrames)
{
video_mc.gotoAndPlay(2);
}
else
{
video_mc.play();
}
}
private function pauseVideo(evt:MouseEvent)
{
video_mc.stop();
}
private function replayVideo(evt:MouseEvent)
{
video_mc.gotoAndPlay(2);
}
}
}

Answer 1

It's not very clear from your code as to what are the three movie clips which you want to control.
Assuming you have 3 movie clips nested into each other, you can call stop() on each one of them to stop their animation (assuming they have a timeline animation)
So if your structure looks like this : a-->b-->c, where a is the parent, b a child of a, and c a child of b, you can call
a.stop();
a.b.stop();
a.b.c.stop();
This is obviously assuming the fact that you have instance names declared for the child properties in the IDE.
Hope this helps.
EDIT:
As per your sent FLA, you should do the following steps to achieve what you want:
Go inside video_mc on your stage, and select Layer 9, and give it an instance name of 'backgroundMC'.
Modify your script like this:
package lib {
import flash.display.MovieClip;
import flash.events.*;
public class Controlstry extends MovieClip {
public function Controlstry() {
// constructor code
addEventListener(Event.ADDED_TO_STAGE,init);
}
private function init(evt:Event=null)
{
if(video_mc != null)
{
playBtn.addEventListener(MouseEvent.CLICK, playVideo);
pauseBtn.addEventListener(MouseEvent.CLICK, pauseVideo);
replayBtn.addEventListener(MouseEvent.CLICK,replayVideo);
}
}
private function playVideo(evt:MouseEvent)
{
if(video_mc.currentFrame == video_mc.totalFrames)
{
video_mc.gotoAndPlay(2);
video_mc.backgroundMC.gotoAndPlay(1);
}
else
{
video_mc.play();
video_mc.backgroundMC.gotoAndPlay(1);
}
}
private function pauseVideo(evt:MouseEvent)
{
video_mc.stop();
video_mc.backgroundMC.gotoAndStop(1);
}
private function replayVideo(evt:MouseEvent)
{
video_mc.gotoAndPlay(2);
video_mc.backgroundMC.gotoAndPlay(1);
}
}
}
A couple of things to note here:
Use MouseEvent.CLICK if you want it to respond to click events. You had used MouseEvent.DOWN
Always give events a type like evt:Event and not just evt=null.
if(video_mc != null) can be easily checked by if(video_mc).
Hope this answers the question.
