ActionScript 3.0 :: Compiler Bug - Var Declaration Function Definition Postcedes External Called Function Execution
Jun 29, 2010
Use Flash CS5 (and AIR, though this does not seem like it would be AIR related) in Win XP 64 I have a MovieClip symbol in my library with the identifier 'Puzzle10Piece10' with the following actionscript attached to frame 1 of the only layer with the following actionscript:
[Code]...
This runs contrary to my understanding of the pre-compiler and code execution order. In my way of thinking, any reference creation and related memory allocation is made when the object is instantiated, and indeed that allocation, unlike C depends not on code order (declaration before use), though this is an order that would satisfy even the C pre-compiler. If I understand the Flash compiler at all, it's not even a question of 'code order'... the symbol is pre-compiled such that for it to exist... for it to be instantiated, the variable would exist before the function would even be 'available' to be called internally or externally. Is my thinking way off, or is this a bug?

I have an AS3 program that calls a function multiple times. The function must return multiple variables, so I created a class for the function to declare an object containing all of these variables. For example, here's my class:
package
{
public class PER
{
[Code].....
Let's say the calling program calls the function, which returns the variables into data_set1 (where data_set1 depends on input variables arg1, arg2, arg3) using:
var data_set1:PER = function_name(arg1, arg2, arg3);
The calling program does some stuff, then calls the function again, but returns the variables into a new variable name, data_set2:
var data_set2:PER = function_name(arg4, arg5, arg6);
My intention is that data_set1 and data_set2 are different (e.g. not linked together).
My question is, given that arrays are passed by reference, will data_set1 be modified to agree with data_set2 upon the 2nd function call? Why or why not?

I'm using an AMF service that was built by someone else. Basically what happens is that some info is passed to the AMF service and it returns true or false.I want to be able to pass in various info to the a function that calls the AMF service(submitTracking) and then get the true or false value returned in onResultSubmit to be passed back to submitTracking.
var screen:String;
var buttonnumber:String;
function submitTracking(screen:String, buttonnumber:String) {

Lets say I want to call a function with an optional Object, how do I write that?If it was a String or a Number or some simple data type it would be:
Code:
function foo(s:String="Sample String", n:Number=100):void{}
But anything I try with an Object just throws an error. For example...
Code:
function foo(o:Object={x:10, b:10}):void{}
...makes the compiler barf, and so does every other version of this I've tried.

I am trying to access a function in a MovieClip that has been added to the stage. Right after loading in the function, I create a function that calls the function in the recently added MovieClip. The compiler does not recognize the Function and when I go into debug mode it shows up as null. I've tried declaring the function in the MovieClip using 3 different methods, but I get the same result.
Code:
function Sleep(){
var Sleep = function(){
this.Sleep = function(){
What I find strange is that when I declare the function on the stage, it looks just fine and I can even see it (as a Function object) in the debug panel.

private function playSound():void
{
_soundChannel = _soundObj.play();
_soundChannel.addEventListener(Event.SOUND_COMPLETE, nextTrack);
}
<s:Button width="35" label=">>" click="nextTrack();"/>
Assuming the nextSound() function looks the same as playSound, typewise... The button click works fine, but the event listener won't call the function because its sending an argument the function isn't expecting. I can change the nextTrack function to be evt:Event, but then the button is sending not enough arguments, and I can't find anything to type it to that will work. I can make a typed function to call the un-typed nextTrack function from the event listener
public function callnextsong(evt:Event):void{
nextTrack();
}

I am having a problem cancelling the execution of a function. When I click on the first of my navigation buttons, I have a fade in tween and an image loader load an external image. If I click on the second navigation button befiore the function for the 1st button finishes, the 1st tween and image loader continue to finish while the tween and image loader function for the 2nd navigation button starts. Essentially, there is an overlap. Is there a way to tell the 2nd navigation button to stop all other functions before it starts its own function? I suspect it has something to do with stopImmediatePropagation, but I am unsure of how to put this into the function.

So basically I have a component with my event dispatched[code]...
So problem is with my static function's showConfirmation handler, if I go through debug, it just skips that function and continues doing myDispatchedEvent. Why doesn't anonymous function inside showConfirmation function execute?

Ok, a simple situation: say I have five fairly complicated functions on one frame. I define all my functions, what they do, etc. After all that, I call all five functions in a row like

error in my movie clip. The code is working just fine. The effects are just what I needed. I have a set of 24 buttons, executing 24 URLs when clicked. buttons are responding on rollover, onRollout and onRelease states.But the problem is when I click the butoons randomly and very fast, multiple buttons remins in onRelease state (as if more than one button has been selected). I do not undetastand wheather this a problem with my coding or problem with my settinf in flash or a bug in flash itself (i'm too small to detect a bug in flash though!!). My setting are: actionscript 1. fps 30.

I'm new to flash/AS and trying to create a flash movie that shows a frame (1) which has a 'next' button to move to second frame(2), pauses uses a timer, before moving onto the next frame (3) which then has a 'next' button to move to the third frame (4).I'm building a presentation where the user has to pause to read the instructions on frame 2 before the next button appears.My two Action Scripts are, on frame 1 :
Code:
stop();
next_btn.addEventListener(MouseEvent.CLICK,next_btnMouseClickEventHandler);[code]....
It doesn't seem to like me calling the same function in two places (frames 1 and 3) and gives me an error '1021 Duplicate Function Definition' but surely that is the point of a function, that you can call it many times? I have worked around it by calling the button and the function a slightly different name each time it is used but this just don't seem right.

I have a function and Im trying to change its argument from one file to multiple files that I don't have to define in the code. After mucking around for a little bit I found a way to make it take one unnamed at the time file but not multiple
function playFlash() { $(""#" & video_id & "_preview"").click() }
I'm kind of self taught in this subject and made up terms as I went.

i know that the problem arises from naming two functions with the same name, and i fixed that. i have also learned that keyframes mean nothing to a compiled swf, and so i cant copy/paste the code and change a couple of variables further in the timeline, i must again rename the functions. Im trying to see if there is an easier way to do thisi have 3 buttons, all 3 of them move the movie clip to a different frame. when the playhead is moved, the movie clip animates for a few frames then comes to a "stop" keyframe. At this point, each button is supposed to take you to a different set of frames, animate, stop and rinse and repeatcurrently, my AS looks as follows (frame 1)
ActionScript Code:
rear_switch.addEventListener(MouseEvent.CLICK,fl_ClickToGoToAndPlayFromFrame);
function fl_ClickToGoToAndPlayFromFrame(event:MouseEvent):void

I am trying to teach myself the workings of Flash in CS3 as I would like to teach myself some web design and eventually work until I know enough to do commission jobs. Right now though I really don't have anything to create so I decided to make a myspace profile in flash. I created a layout in flash where I have a series of 80x80 images that are 10px apart. There is another layer where each image has a corresponding clickable button with a defined instance name. There are a total of 15 buttons but when I try and export it to flash movie to see if it work I get 14 error messages telling me I have error 1021 which is discussed by adobe here: URL..."1021: Duplicate function definition.

I keep getting this 1021: Duplicate function definition.
I googled it, but couldnt exactly find how to fix it, im very confused.
the bold lines are the duplicate function definition that flash tells me.
Code:
window01.pbtn01.addEventListener(MouseEvent.MOUSE_OVER,onBtnOver,false,0,true);
window01.pbtn01.addEventListener(MouseEvent.MOUSE_OUT,onBtnOut,false,0,true);
window01.pbtn02.addEventListener(MouseEvent.MOUSE_OVER,onBtnOver,false,0,true);

i have a flash movie that is part of quite a large project. it is the second swf file to load and contains a few different elements that stay throughout the whole "shabang"
i am using cs5 and cs5.5 to publish. and each time i try i get a
PHP Code:
1021: duplicate function definition
error message (something that i never got in cs4)
reading up on it and asking a few people it looks like it is being called elsewhere - but it is not in any other class files and is not on any frames within the fla's either!!! even when i try to change function names it gives me the same error (also when i remove the path the class file from main i still get the error!)

I have been building my website using a simple mouse event click system that makes movie clips play at specifically names keyframes. it took me a bit, but I got it right and the code was simple. here is an example of the code that works:
films.addEventListener(MouseEvent.ROLL_OVER, btnOver1);
function btnOver1(event:MouseEvent):void{
sketch_5.gotoAndPlay("f_over");
}
Pretty simple stuff. but now I am working on a paid project for someone, and it is a bit more complicated in scope, but essentially I would be using the same code over and over again. it's a glorified slide show. but I ran into a problem. I used this code, which is the same (with different names and mouse event) as the one above.
mcLifeLED.addEventListener(MouseEvent.CLICK, Light_Type);
Function Light_Type(event.MouseEvent):void{
mlights.gotoAndPlay("p_life");
}
Its telling me that "Function Light_Type(event.MouseEvent):void" is wrong with this message "1071: Syntax error: expected a definition keyword (such as function) after attribute Function, not Light_Type." I may be wrong, but from what I can read in it, it's telling me that the function I named about "Light_Type" can't be found...

I have downloaded the trial version of Flash CS4. I have always been able to quickly learn and execute new programs, and after watching a bunch of great videos from this site and some tutorials, I was able to create nice Flash animations within hours. I thought that this was amazing... until I tried to make a few functions in AS3 to add hyperlinks.

var url:String = "[URL]";
var req:URLRequest = new URLRequest(url);

What I'm looking to do is create a banner that transitions between different photos while there are small square buttons on the side that when the user clicks on them, it jumps to the corrosponding frame where a new photo begins showing. I've seen it a bunch of times on other websites.After following the advice found here: http:[url]....Everything was going well until I hit a snag. When trying to preview my movie I got the following error:1021: Duplicate function definition
Now, I know there is a very obvious error here in my button scripts, but as I said, I have no idea what I'm doing. Can someone look at my code and tell me what's wrong and what I should change? I'll post all five scripts.The instance names by the way are "sidebutton1" thru "sidebutton5" if that's any help.Here's my codes for each of the five buttons (one of these code bits per button)
sidebutton1.addEventListener(MouseEvent.CLICK,f);
function f(e:Event):void{
