Help! Need mouse click to play 2 different child movie clips at the same time

[arjayc]

Hello and thanks for the help in advance!

I'm trying to get frame 2 of a movie clip (one_mc) on the main timeline to play, while at the same time it triggers frame 2 of the child movie clip (two_mc) to play. Movie clip two_mc is in the movie clip one_mc. My code is below, but I keep getting an null object error. I've tried a bunch of different combos, but nothing seems to work.

/*Play button plays frame 2 of one_mc, frame 2 of two_mc also plays*/

play_btn.addEventListener(MouseEvent.CLICK, play);

function play(e: MouseEvent): void {
one_mc.gotoAndPlay(2);
one_mc.two_mc.gotoAndPlay(2);
}

Is it impossible to get one mouse click to play frames in two separate movie clips?

Thanks!

Hi,

Your code will work, its just that two_mc does not exist in flashes eyes until it reaches frame 2 of one_mc, so therefore will throw an error when trying to call it before it exists, try putting the two_mc on frame one of one_mc and make it invisible, then make it visible on frame 2 of one_mc.

I think you can follow that

I follow, however I'm not sure where to put the code. Do I put it on the main timeline or frame 1 of one_mc? Right now on frame 1 of one_mc I have:

two_mc.visible = false;

On frame 2 i have:

two_mc.visible = true;

And it's not working. Thanks again.

Hi,

Perhaps you can do it like so,

play_btn.addEventListener(MouseEvent.CLICK, plays);
one_mc.two_mc.visible = false;

function plays(e:MouseEvent):void
{
    one_mc.gotoAndPlay(2);
    addEventListener(Event.ENTER_FRAME, checks);
}

function checks(e:Event):void
{
    if (one_mc.currentFrame > 1)
    {
        one_mc.two_mc.visible = true;
        one_mc.two_mc.play();
        removeEventListener(Event.ENTER_FRAME, checks);
    }
} 

no need for code in the movieclips, just the regular stop(); wherever you needthem.

the code goes on the main time line, two_mc is on frame one of one_mc.

I believe you will need to change the function play to something different (like above) as you will get an override error

It works! However, it breaks the other two functions I have attached to play_btn, which is to play a sound and show a selection around the clicked button (both on the main timeline).

Hi,

Well to help you any further we would need to see a working file as trying to guess what you have set up is pretty hard to achieve.

[arjayc]

I really appreciate the help. I'm building a prototype/demo that is a little sensitive and don't feel comfortable posting it online.

Hi,

Well I can only suggest that you put your other function calls within the other one!!
Maybe make a small skeleton file of what it is you need, then perhaps things can be sorted for you.

good luck

This code is probably messy as I'm somewhat new to as3 and I'm not sure if seeing all of it helps at all. If needed I may be able to put together a dummy UI. This includes the code you suggested I use earlier...

play_btn.addEventListener(MouseEvent.CLICK, plays);
one_mc.two_mc.visible = false;

function plays(e:MouseEvent):void
{
one_mc.gotoAndPlay(2);
addEventListener(Event.ENTER_FRAME, checks);
}

function checks(e:Event):void
{
if (one_mc.currentFrame > 1)
{
one_mc.two_mc.visible = true;
one_mc.two_mc.play();
removeEventListener(Event.ENTER_FRAME, checks);
}
}

/*plays sound*/
play_btn.addEventListener(MouseEvent.CLICK, onClickPlay);

var mySound:Sound = new Sound();
var myChannel:SoundChannel = new SoundChannel();
var req:URLRequest = new URLRequest("sound.mp3");
mySound.load(req);

function onClickPlay(event:Event) {
myChannel = mySound.play();
}

/*button selection array*/
play_btn.addEventListener(MouseEvent.CLICK, onButtonSelect);

import flash.events.MouseEvent;

var group:Array = new Array(play_btn, stop_btn, fwd_btn, rev_btn, pause_btn);
var selectedButton:MovieClip;

function onButtonSelect( event:MouseEvent ):void
{
selectedButton = event.target as MovieClip;

for each(var btn:MovieClip in group){
btn.setSelected( btn == selectedButton );
}
}
