ActionScript 3.0 :: Nested Button Referencing Parent MC?
Dec 4, 2009
I am working on a tool for use in our office which creates XML. At this point I am working on getting an error message to appear when the user enters incorrect data in one of the textfields. I have a MC which contains my error message as well as a button. The button will move the MC back off of the stage. Everything works up to the point where I click the nested button. I suspect there is a problem in referencing the parent MC from the button.Here is the code for the entire project. I am sure there are more than a few errors since I am relatively new to AS
import fl.controls.RadioButtonGroup;
import flash.display.*;
load_file.addEventListener(MouseEvent.MOUSE_UP, do_load_file);//load file button click.
[code]........

I have 2 child movieclips nested into one working parent movieclip, then the parent movieclip is animated. The nested working parent movieclip should move to the side once a child movieclip is clicked. Currently, the parent is unaffected by clicking on a child movieclip. What gives?
Below is a layout of the movieclip:
Button List Box
| |
v v
Subparent(groups btn and list box)
|
v
Parent(animated)
I need the parent to animate once the child Button is clicked.

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?

I'm currently making a platform game and when the player shoots i want to add the bullets to the stage. The players gun class is in charge of adding bullets. The "players gun" is a child of "players gun holder" which is a child of "player" which is a child of the stage. is there a better or more dynamic way for the "players gun" to add bullets to the stage rather than using parent.parent.parent.addChild (bullet);

The IDs for all tags in an MXML component, no matter how deeply nested they are, generate public variables of the component being defined. As a result, all id properties must be unique within a document. This also means that if you specified an ID for a component instance, you can access that component from anywhere in the application: from functions, external class files, imported ActionScript files, or inline scripts.
Which is fine if your application is all contained within one MXML, but I'm having trouble referencing IDs of components within Modules, and then inside ViewStacks/Navigation Containers within a given Module.
If I can reference a module with FlexGlobals.topLevelApplication.myModule, shouldn't I be able to reference a Panel called myModulePanel with the following?

I usually would call the parent of my class by something like:
MyCustomClass1(parent).thisFunction();
My problem is this works if I know the class of my parent. How do you handle the case where you class could have a parent of 2 or more possibilities?
parent.thisFunction(); // throws error of course

Each of these children has an index value assign to it for the purpose of relating to an XML file, but that's beside the point. Those children have other children eventListeners that call a tween function. That tween function wants to tween the first child.First question: what is the proper syntax for referencing the parent and getting that index value? Does this work, with currentTarget being the child that called the function:var something = e.currentTarget.parent.index;If not, how can I get that index value?Second question: In order to determine which of the first children the tween is applied to, I could write a conditional that checks the index value and tweens based on that. Is there an easier way to do this? And what conditional would work best? I'm thinking if() else() but I'm relatively new to as3 so if there's something more efficient I'd love to hear it

I have an array defined in the main timeline to store some values. At some point of time, I am dynamically adding a movieclip to stage using attachMovie and then using a movieClip.onEnterFrame event to set one of its values by referencing to one value from the main array.(Sorry if the following description sounds a bit confusing. I am attaching a part of the code below to help describe the situation) The problem is that it is not able to retrieve the value from the main array no matter what I try. I tried adding a "_root" befor the array name and the index array id but it did not work. Not only that but the trace shows that it is able to retrieve the index id as well as the full array but not any particular value from the array - as in, trace(arrayname) outputs all the values from that array but trace(arrayname[a][b][c]) gives an output 'undefined'.
I have managed to make it work by creating a temporary variable to store that particular value just before the onEnterFrame event kicks in, but I would love to know why it is not working the way I thought it should. Here is a part of the code. If someone needs more info about the code then please ask and I will give it in the next post (The full code is way too large to be posted here)
ActionScript Code:
//------In main timeline
var movesNum:Number = 0;

I have this MC attached to the stage with an instance of say: insA, then within this I have another called say: insB, then finally another one within insB called say: insC.so normally to access the third one I would use: insA.insB.insC do something.I have this button within another MC called say: '2ndinsA', so when a button within '2ndinsA' is pressed I need to perform 'something/move' onto insC.
Now within the class attached to '2ndinsA' i have the parent.getChildByName("insA") code and its seemed to grab the 'insA' and I could then move it, but its the insC that i want to move.How can I then reference the 'insC' within that MC )'insA', i have tried several ways but all come up short (errors galore)

I would like to know the way to prevent a child swf from referencing its parent swf stage width/height?
for example, i created a child swf that loads image and center it on it's stage. As a stand alone its fine but i loaded it with parent swf, it centers on the parent swf instead.

Ok im rather new to flash so ill do best i can to describe this. I have a HealthBar movie clip with 3 layers, bottom layer is just a red rectangle, middle layer is a green rectangle that is a movie clip, and the top layer is just a border. the green rectangle movie clip has an instance name of bar. i put my HealthBar on my stage with an instance name of healthBar and i change it when the players health goes down by calling _root.healthBar.bar._xscale = health where health is 0-100.
this works all fine and dandy. now i have a movie clip of MiniBoss with an instance name of miniBoss# where # is a number of the layer depth when it is created. in the MiniBoss movie clip i have an instance of the HealthBar with an instance name of bossHealthBar. i tried to call from within the MiniBoss class bossHealthBar.bar._xscale = health but i get an error that there is no property of bossHealthBar.bar._xscale. how do i access the bar in the HealthBar in the MiniBoss clip from the MiniBoss class in its onEnterFrame() method?

It's me again and I'm running into a problem. So, I have this movie clip that is nested inside multiple movie clips. I want to tell Flash to perform an action when that movie clip hits another movie clip in the main timeline. It's just collision detection for a game using the hitTestObject code. I was thinking of using MovieClip(root), but that won't work since it's nested so much.

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 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'll give a complete explanation of what I'm trying to do. I have a video player as a separate SWF. In this video player I have a VideoContainer class extending Sprite, which contains the video and a control bar with specific video buttons.
This SWF is loaded in another main SWF, which has a menu that is on top of everything else. When I click "Fullscreen" in the video SWF, everything goes smoothly, except the menu remains on top of the VideoContainer object.
I need a way to change the display order of the loaded SWF, to put it on top of everything else on Fullscreen and change it back when Fullscreen goes off. All this needs to be made inside the video player. Also, the configuration of the children can change (the video player can be loaded in different places in the main SWF), so I can't use a certain unchanging path.

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 a Flex tree with an ArrayCollection as data provider. The collection holds an array of CategoryVO objects. Each object can have another array of CategoryVO objects inside it's "child" attribute. This way the tree displays the data correctly. Now I want to get the parent of a specific item, e.g. tree.selectedItem. Using XML as data provider the item parent is avaiable thorugh the parent() method. But I can't convert my data to XML. How can I get an item's parent? Perphaps using the tree's dataDescriptor?

Setting properties of a nested clip from the associated document class of the parent clip. I am developing a Jigsaw puzzle in Flash. I am developing a class for puzzle piece. The code of the PuzzlePiece class in given as follows.
PuzzlePiece class
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class PuzzlePiece extends MovieClip {
private var pieceX:Number;

Is it wrong to access it like that. The PuzzlePiece is the export for a puzzle clip. For the time being I am hard coding the dimension as 60. I have aloso uploaded the fla and as files. [URL].

Is it possible to have the child movieclip rotate separate of the rotation properties assigned to the parent? so ultimately giving the child element it's own axis?I've customized Lee Brimelows (gotoandlearn.com) 3D carousel to spin on the x axis to make it a vertical carousel. I've also rotated that by 45 degrees on the y axis to see all the items, and wrote a snippet of code to hide the left portion of the carousel. The entire carousel is contained within the 'container' movieclip, and inside of that are my carousel items (as seen below), with the larger item being the item in focus.
On rollover of the item in focus, I want to rotate it so it faces the viewer (as seen below),basically removing the 45 degree rotation applied to the container.The problem i'm running into is when you rotate the container (changing the rotationX of the container), the axis basically rotates with it, so when i rollover the next item 'in focus', the following happens..(in the example where it appears how it want it to, the carousel is at a rotationX of 0, so it works fine)

I have a nested movieclip, which I shall refer to as Menu.a.b This is passed to a MouseEvent function using e.currentTarget
I now need to run a command (indexOf) on Menu.a, however only have Menu.a.b saved. How can I refer to Menu.a as a function of Menu.a.b
I've tried Menu.a.b.parent, and that hasn't seemed to work, nor has a few other attempts involving the MC function.

how do I reference a button that has been loaded dynamically?Furthermore, is it possible to use the removeMovieClip() method with a button that is inside the movieClip you are trying to remove?Simply put, I've got a movieclip that is loaded via the "attachMovie" method. There is a button inside that says "Close". I am trying to use the removeMovieClip() method on that button, but it's not working. I can put a button on the stage, and use the same method, but it doesn't work.
