ActionScript 3.0 :: Nested Child Calling Root Parent Function ?
Jul 18, 2010
I'm switching from as2 to as3 and everything was going swimmingly with my new site until i tried to use a _root call to a function on the main timeline by a loaded movieClip that is loaded nested into 2 other movieclips. the movieClip needs to tell the _root when it's done playing so the root knows to load the next one in line through a php call. Everything works except for the _root call. In as3 there's no such thing as root anymore so I figured no big deal, i'll just find out what the new thing is and holy crap wtf! I can't figure this out!! I've read from doing stuff like custom eventLisnters (which i am trying now) and casting the root as a movieClip and then I read this whole crazy tutorial on building an event structure and the proper MVC way of coding and blah blah blah ALL I WANT TO DO is tell the _root that the loaded MC has reached the end of its timeline. Basically if it were as2 i could just go _root.loadNext(); and it would work.how to make a loaded MC talk to the _root timeline and call a funciton from there?

I have setup a video interface with a stock video player in the parent mc. In the same swf next to the player, I have a mc which is a video thumbnail chooser. The thumbnail buttons are located two levels down within this mc (nested within two mc) in order to facilitate the scrolling independent of the player. In the parent, where the video player lives, I placed a function:
function vid1(event:MouseEvent): void{
pubPlayer.source = 'Steve480.flv';
}
In the child mc where the thumbnail buttons are, I want to call the parent function like this:
vid1_btn.addEventListener(MouseEvent.CLICK, vid1);
None of my clips are externally loaded, just nested in the same swf. How can I talk up or down the movieclip ladder?

May i know how to call child function(layer 2) in parent(layer 1)?
Layer 1 (Parent)
function changeAction():void{
changeColor();
}
This method will give me the error -> Call to a possibly undefined method changeColor.
Layer 2 (Child)
function changeColor():void{
trace("success");
}

I have container swf which includes navigation that loads child swfs. Each child swf is loaded then visibility is set to false. Once a child ( an image gallery actually) is loaded it is possible to jump from image to image. What Id would like to be able to do is call a "clean up" function that returns the child to its initial state when anothor nav link ( a different gallery) in the parent is clicked. But I do not know how the syntax is supposed to be written or if its even possible.
Ideally it would look something like this in the parent container swf:
ActionScript Code:
function swapSectionIdentity(e:MouseEvent):void {
setChildIndex(background_home, 0);
getChildByName("identity_mc").visible = true;
[Code]...
the behavior I am attempting to avoid is when a child swf is loaded ( an image gallery) and then the child is invoked to display a particular image in it, afterwhich a main navigation link is clicked the current gallery is set to visible = false and a new gallery is set to visible = true. But when you return to the previous gallery the last image viewed is still showing. I want to be able to reutrn to galleries inital state as it is hidden. make sense?

I have setup a simple video interface. The video player lives in the parent swf. The video list chooser is loaded as a child swf. In this child swf, I have some video buttons nested within two movieclips in order to facilitate the scrolling feature. I am trying to get the movie buttons to load flvs into the component flv player in the parent swf. I have declared the functions in the parent and I am trying to call them in the child:Code in the Parent:
function vid1(event:MouseEvent): void{
pubPlayer.source = 'vid1.flv';
}

I am adding a child .swf from the parent with a simple button. If this button is then clicked multiple times, the child is added multiple times. So I added the ".visible = false" to the button when clicked so the button cannot be clicked while the child is open.
Now, there is "Close" button on the child .swf that uses "this.parent.parent.removeChild(this.parent);" and would now need to set the parent button back to ".visible = true".
I have tried MovieClip.parent.parent.resetButton(); and parent as MovieClip.resetButton(); and many variations of the code. I get no errors but the code doesn't work either.

If I need to call a specific function in the parent application from a child in a flex project, what's the best practice for this? Would it be to dispatch a custom event from the child and have a listener call that function? Or to directly call the function with FlexGlobals.topLevelApplication?

I'm using a PreLoader as a parent SWF that loads the actual website as a child SWF. In the website SWF, the child SWF, will MovieClip(root) still work and refer to it's own root, or the PreLoader's root? And would I still access the websitite's document class (the child's document class), through MovieClip(root)? What if both files have a document class?So my main question is how do document classes and MovieClip(root) behave in the scenario when you have:
Parent SWF - document class, MovieClip(root)
|
Child SWF (loaded by parent) - document class, MovieClip(root)

In my child constructor I use MovieClip(this.parent).blablabla() to retrieve info, yea I know I can pass it through the constructor, anyways I keep getting errors anytime I try to use MovieClip(this.parent) in the constructor, it gives a refrence error saying it's null.
Why doesn't that command work, is there a way around it (other than the constructor)? Is it because it's bad design? I'm calling a function that has alot of data, so I'm just passing this to the child and using the passed this data to call the parent atm, looking for a better MovieClip(this.parent) solution.

I have a very specific AS2 parent/child movie clip issue. I have a main Character movie clip which contains as nested frames each profile of the Character (front,back,left,etc). Within each of these child profile MC frames, animations for those profiles are further nested in frames. Then, essentially I have movement code as part of the key listener:
Code:
switch(Key.getCode()){
case 87:
Character._y -= 10;
Character.gotoAndStop('Back');
Character.gotoAndStop('walk');
break;
[Code] .....
And later code to reset to the character's resting frame after key release:
Code:
switch(Character._currentFrame){
case 5:
Character.gotoAndStop('Back');
break;
[Code] .....
The problem is that when I try to Character.gotoAndStop('Front'); after key release, flash thinks, you're already on the Front frame (because the walk animation is a child of that MC and is already playing). Therefore the walk animation just keeps playing after the key has been released.

I'm looking to create an animation loop in Flash. The base character animation I have is 27 frames. However to have the background move at the correct speed, the entire animation is 432 frames.
Since I am making the animation so long anyway, I want the character to blink halfway through the animation loop. I went into the head symbol and extended its animation from a single frame to 432 frames. Halfway through that animation I swap out the image for one that is blinking (3 new images added for the blink).
So, now the symbols are nested like: 432 frames -> 27 frames -> 432 frames
But it doesn't seem like Flash is smart enough to animate it as I would expect. It only repeats the first 27 frames of the child symbol.
The next thing I tried was extending the 27 frame character animation out to 432 frames. I did this by copy-pasting the character animation 16 times. But this also does not work because copying the keyframes also copies the position of the child animation's playback. This causes the animation to constantly reset and never reach the blink.
I also tried using the copy motion option, but it didn't seem to do anything different than copying keyframes.Is there an easy way to make this animation work? I can't possibly need to manually position a total of 576 keyframes (there is actually another level to the nesting which does not use any tweens, just keyframes) could I?

I have uploaded a ZIP file that includes the following files:
- main.fla
- child.fla
You can download to review my code (very small 16kb): http:[url]...........This simple example has a main SWF file that loads a child SWF using the dynamic loader method. Below is the code in the main.fla file:
Code: Select all/*
MAIN SW
*/
import flash.net.URLRequest;[code]........
how do I get both parent and child SWFs to communicate with each other dynamically (to be able to call functions from each other, or pass variables)?

This is kinda complicated, and I'm still trying to wrap my head around the whole concept of OOP. So right now I am building a XML Gallery, and in the FLA (Root) I've added the thumbnails. Everytime the thumbnails been clicked, it will bring up the "Detail" movieclip, which also is created in the root. And inside the Detail movieclip, I am creating a few buttons with an external class. My question is how can I call a function in the FLA (Root) when I click on the buttons inside the Detail movieclip? Note it seems I've successfully import my external class in both the root and the Detail movieclip.

I am a Flash MX user, I have three files named PARENT.SWF, CHILD.SWF, and CHILD2.SWF. The PARENT.swf loads the CHILD.SWF, The CHILD.SWF loads, then the file CHILD.SWF loads another swf file: CHILD2.SWF
Now my question is: How can the file CHILD.SWF unloads itself to avoid overlapping with CHILD2.SWF on the screen. I try the command: removeChild(CHILD); from CHILD.SWF but it doesn't. work.

i've got this mc component i've created and reuse on some sites i've made. It's a real simple shoutbox that grabs info from a database using a php script.What i'd like to do is have this component refresh every 200 frames, which means, grab most current msgs and post them in the database.so for example, i have a movieclip called MC1. there's a function in MC1 that goes like: grabdata = function() {}; this basically calls the php scripts, loads the info, and so on.i wanna call this function from the root or even a parent MC.I have considered using prototypes or a class, but i dont think it's really necessary for something that seems basic enough.

As entitled in this post, suppose we have wrote in timeline
[code]...
The problem emerges because I want to use local variables (i.e. a and b) to perform tasks of myF2 on several clips at the same time but started, say, a half of second one after the another. I don't want to use timeline variables because all clips must start with the same initial variable values.If it's impossible to use setInterval like this, how is it possible to fix the problem I described here? .This code is for Flash Professional 8.0

new to actionScript and trying to finish my final project, and i'm banging my head on a brick wall now, my question may be easy for some pros, basically i've loaded an external swf from a button at main.swf
[Code]...
this works fine. then i'm trying to disable the button function while the swf is loaded. I add another eventListener to the same button. function disableMenu( e:MouseEvent ):void { button1.mouseEnabled = false;}
that works too. ok now comes the problem. I have a close button on my child swf("content1.swf) to close itself and returen to main swf. but I want the button on main.swf to work again. so at the close button I add another eventListener hope to enable the menu. (note this is on the child swf!)

So, my problem, I have a Parent swf file that loads a bunch of smaller swf files. When I click on a button in one of these loaded swf files, I want to be able to call a function from the parent swf. Once called, the function manipulates things MC's within the parent swf.

new to actionScript and trying to finish my final project, and i'm banging my head on a brick wall now, my question may be easy for some pros,[code]this child swf is loaded from xml. and the close button is created by using AS file. The "button1" is just on the stage of the main swf. Maybe these make some difference so i can't just point it back using (root)?Any idea how do I resolve this? Or am I not supposedd to do it this way at all?

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.

i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).
