ActionScript 3.0 :: Nested Functions Not Working?
Mar 14, 2012
I initially posted this in the AS3 NEWBY forum but I think it probably belongs here. On stage I have 5 boxes, the letter A and two buttons labelled button1 and button2. The letter A is also defined as a button labelled AA_btn. When I click on button1 I want a condition to be set so that if the letter A is clicked, boxes 2 and 4 will disappear. Conversly if I click on button2 I want boxes 1, 3 and 5 to disappear. To do this I have nested the letter A and B functions under the button1 and button2 functions.
I also have a reset button which resets the display of all five boxes back to their original display.Everything works fine when I press Button1 to set the first scenario. When I then click on the letter A boxes 2 and 4 disappear. (perfect). Everything also seems to work when I press the reset button, ie: all five boxes reappear.

For some reason I can't get this nested set of functions to work, it executes the first tween and the tween invoked after motion of the first is finished but it doesn't ever get to the third!
ActionScript Code:
var t1:Tween=new Tween(p1,"rotationY",Strong.easeOut,90,0,50,false);
var t1x:Tween=new Tween(p1,"x",Strong.easeOut,-900,0,50,false);
t1.addEventListener(TweenEvent.MOTION_FINISH,onMotionFinished);

I've got a few MouseEvent listeners outside of a function that contains nested functions that need to use the functions attached to the listeners.
button1.addEventListener(MouseEvent.ROLL_OVER, buttonOver);
function navigation (): void {
if statements;
[code]....
I keep getting an "1120:Access of undefined property buttonOver" error. I know it's because the EventListener is outside of the function "navigation" but I need it to be accessed by other functions later.

I have a few rows of movie clips making a menu. Because I will be adding to the number of MC's I use a variable called "menuitems" and run a FOR loops to assign all of these MC's onrollOver, onrollOut and onRelease functions. I'm doing this to save having to assign these functions to them individualy (as they are the same functions). Its works fine, but when the MC is released it is told to jump to frame 2, where there will be nested mc's that need to be able to clicked and rolled over. Because the parent movie has event functions assigned to it they seem to overide them. Is there a way around this? I tried placing a transparent MC on the 1st frame of the movie and trying to assign the onRelease function to the "hotspot" but it doesnt work. Here is my code:
Code:
function buildthumbs () {
for (i=1; i<= menuitems; i++) {[code]...........

I have this menu_mc appearing on stage on RollOver.Inside this menu_mc are 5 other mcs that are also supposed to react on rollOver.But : the rollOver works only on the menu_mc, the rollOver on the nested mcs no. I put all the script on the main stage, accessing my nested mcs with the "insert target path".I tried also to put the script of the nested mcs inside the menu_mc movie clip, but it does not respond.What do I do wrong ?
import mx.transitions.Tween;
import mx.transitions.easing.*;
orig = Menu_mc._x;[code].....

I'm starting to get a handle on some AS3 basics in terms of building nested classes or packages or whatever the proper syntax terminology is.
Now I have two instance functions:
1 - parseXML
2 - loadImage
I have these 2 functions working together using an eventHandler. Once the XML is parsed the aim is to load an image. Sounds pretty common right?
When the image loading commands are in the parseXML function they work fine. But then when I put the image loading commands in separate function titled loadImage and trigger it using an eventHandler onComplete, it loses my variable and instance definitions.

I have run into this problem twice now, for two different reasons. Technically the more recent time it isn't a roadblock, but rather I just want to avoid memory waste by not using nested functions for my event handlers.[URL]
The reason I've come to this forum is that I always went on my merry way, defining event handler functions on movieclips within functions, until today, I read "I really didn't like the idea of defining an event handling function within a method of a class. I don't think nested functions are a really good practice." in the archives of the BIT-101 blog. So I decided to try to extract these and assign only a reference to each movieclip that needs the function. The problem is, it's in a class - and I need access to the properties of the movieclip from within the function. I figured I might be able to extend MovieClip, but I don't want anything in the library, so I run into the problem of how I would use my new movieclip-extending class - I read something about using the Linkage name of "__Packages."+[classname] - is that really proper? Either way, my final question is - if it's not good practice to use nested functions within the class, where do I create my event handler functions?

I have my function on frame 1
Code:
function backhome(event:MouseEvent):void
{
this.gotoAndPlay("mapbegin");
}
At frame 10, I have a movie clip that animates and stops. Inside of that movie clip is a button that I want to go back to frame 2 when someone clicks on it. I want to be able to click on that button and call the function above.
panamacitybeach.returntomap1.addEventListener(Mous eEvent.CLICK, backhome);
When I put that code on the movie clip keyframe on the root timeline, I get this error.
TypeError: Error #1009: Cannot access a property or method of a null object reference. at intmap_fla::MainTimeline/frame1()
The addEventListener is laying on the keyframe in which the movie clip is. Why can't I call that function later on where the movie clip shows up?

I'm having problems with the scope of nested functions. I have a movie clip: "MC_clip" inside that movie clip there is a button: "inside_button". when users press "inside_button", I want the movie will jump to play frame 5 (main time line). how do i refer the stage from inside a movie clip?? another question is about the other way: how can I call to a function that is declared inside a movie clip?? is that movie clip have to be an instance on the stage??

How would you go about accessing a function or variable from a parent clip if the clip accessing has been loaded using the Loader() constructor in AS3?

I have 3 movieClips call A,B and C, and added to stage one after another, in a nested manner. where a is parent of b and c, b is parent of c and child of a.However I get an error after trying to add child to movieclip c into b?[code]

I'm creating my first AS3 project and I've already hit my first snag, nested display objects (aka buttons and movieClips). Let's say you create a movieClip and place buttonA on frame 1 and buttonB on frame 10. You create a class for that movieClip that tells it to jump to frame X after evoking a custom method. With the same method you want to assign the buttons on that frame their functions, but you can't because Flash thinks that DisplayObject does not exist. How do you make sure all DisplayObjects for a frame have been loaded, so that you can reference them?
I have figured a way around it by using the ADDED event listener. Apparently this event is triggered every time any DisplayObject is added, whether it is nested or not. What's interesting is the number of children (numChildren) for the parent movieClip stays constant. So, this code takes advantage of that fact.

I have a simple getURL on a movieclip. Looks like this:
Actionscript Code:
var galURL:URLRequest=new URLRequest("gallery.html");nav.gal.addEventListener(MouseEvent.CLICK, onClickGal);function onClickGal(evt:MouseEvent):void { navigateToURL(galURL, "_self");}
there seams to be some problem with the getURL functionality when it is not on the top level. how to address this? I did a search for the topic but the spinny applet just keeps spinning and spinning when I hit search.

I have two scenes on my flash file viz., Scene 1 and Scene 2.
I have created one nested button i.e., button inside the movieClip and one normal button as in the following code.
ActionScript Code:
jan_btn.onPress = function() {
gotoAndStop("Scene 2", 1);
}
[Code]....
The problem is the first button jan_btn works and it goes to Scene 2 when it is clicked. But the second nested one i.e., button inside the scroll_mc movieClip is not working.
I have kept jan to dec buttons inside scroll_mc movieclip (it will scroll) and kept on stage.
Why nested button i.e., button inside movie clip is not going to Scene 2 when it is clicked?

I have 2 nested move clips in this order.
mc_a (grand parent)
mc_b (parent)
[Code]....
Now, I have a button on the stage. I am trying to load mc_a on stage using the linkage, and trying to load an image that replaces c_inst.
I am using:
on(release)
{
_root.attachMovie("a_call", "a_called", 1)
_root.loadMovie("image1.jpg", _root.a_called.b_inst.c_inst)
}
But so far it only attaches the movie, doesn't load the image.

I have these two functions which both happen on an onEnterFrame event;"basichittest" and "photo". They each work by themselves, but not together.I attached the fla file.I commented out lines 6-10 and line 58.I want the red dot "photodetector" to get brighter as the mirror slides to the right. I also want the beams of light to bounce back and forth when the drag happens.If I uncomment the offending code, the beams no longer bounce, but the dot behaves the way I want.

I can usually fumble my way through things *and i usually like to figure things out on my own* I did find a few other threads on this, but the only conclusive thing i came across was the _lockroot = true; which works beautifully.. untill u navigate to the drag and drop portion.

I have these little menu tags which move down when you roll over them. Then, if you click one, it stays down. Then the other menu tags move down when you roll over them, until you click one, at which point the previous tab moves back to original position. (I'm sure that makes little to no sense... so look here: [URL]. Anyway, it works great for the first couple of seconds, then after a while (especially after a click) some of the menu's don't return to their previous position. My fla is attached, but here is my script.
PHP Code:
//import classes
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
import flash.display.MovieClip;

I have two functions that work individually, but not together because they're both onEnterFrame functions for the same mc (which is not possible).
Here's the code from the mc "A" class file:
Code:
function onEnterFrame(){
removeA();
connectT();
}
This works until the next function runs...
function removeA(){
if (this._x < 500){
removeMovieClip(this);
}} var strandID:Number
function connectT() {
[Code] .....
Explanation of code: mc "A" hits "strandT" and the two move together across the screen. Mc "A" needs to disappear when it hits x = 500.

I have a serious situation regarding the onRelease Funciton not working properly.I have a FVLplayback componant inside a flash project inside a movie clip. Inside that movie clip I have two layers, One for actionscript and and the other for the actual component which contains instance name of 'myPlayer' (without quotes)[code]That cameraRoll is the instance name of another movie clip I have located in the movie clip as shown in path above. Inside that movie I have rollover, Rollout effects. The actionscipt is in an invisible button right on top of the objects. The actionscript is:[code]The objective: the movieclip to carry out the rollover Rollout effect and to have the function that will start the video.The Problem: When I run the flash project, it does the effect but won't start the video. If i move things around, I can have the video start playing but then the button won't do the rollOver, RollOut effects.
-the path to the video component:-root.menu.video
-the path to the movie clip taht contains the timeframes for rollOver/rollOut effects )which contains invisible button on top of everything. root. menu.cameraRoll
