Flex :: Measure Various Phases Of Code Execution?
Aug 12, 2011
Is there a way to measure the average time it takes my code to run and each frame to render for my Flex app? More specifically, I know how to use getTimer() but I'm not sure about which events I should listen to in order to do this. I was reading this post and am not sure how you'd figure out how long the actual rendering took (it would seem like it may be the time between the RENDER event fires and the next ENTER_FRAME event fires, but I'm not sure). Also, not exactly sure where the user code happens, or whether I should care about EXIT_FRAME and FRAME_CONSTRUCTED. [code]...

I have written a small bit of actionscript code which is designed so that small objects fly across a window from left to right at varying speeds, and then get moved back again with different attributes once they reach the right edge. The code is fully functional.My problem is that this eats a huge amount of system resources, and runs slowly on a 1Ghz machine. Is there a more efficient way to achieve this?

How would I pause the execution of code? In Python it would beCode:pause(number of seconds)but I have no idea how to do this in AS3. I don't want to pause the frame, only the execution of the code.

I am trying to set a couple of _global variables with if-then statement, and just after this, use these _globals in the code. However, the code moves on before the _globals are properly set. How can I make the code wait (no timers, please) until the _globals are set?

The following code is on a movieclip being used as a button.The code is pretty simple. Originally the code was just the code after the gap. This code loaded up a movieclip (filtermc) off-stage that runs through an xml file and preloads a form. This takes a second or two, and when finished that newly loaded movie tweens into position. The tween code is on a frame in the 'filtermc' movieclip.
The problem is that in the second or two that it takes for this movie to load, people could click the button a second time which messes up the form/movieclip (everything on it is unresponsive, I think because two movieclips having the same name)
Anyway, I decided to solve this problem by loading a transparent blocker movieclilp in front of this button to keep it from being double clicked. This blocker clip is just a movie that has an empty onRelease function in it so that the button below it cannot receive any new clicks. Also, the button goes to another frame where it says "loading..." to provide feedback to the user.
The Problem When I click this button, there is a delay of about 2 seconds before the semitransparent (for testing) blocker appears. In fact it appears just as the filtermc clip has started it's tween into place.
It is almost like this code is running out of order. The traces come back in the correct order so I know it is not running out of order, but why the 2 second delay before the blocker movie gets loaded up? The button also takes 2 seconds to show the "loading" frame. The traces also have the same 2 second delay.
If I comment out the second half of the code (the filtermc part) then the blocker movieclip pops up instantly and the button changes frame instantly.
PHP Code:
on (release) {
//problems occur if button is pressed twice before filtermc scrolls into view
//this button must be disabled until the filtermc finishes loading

I try to execute a code on my Stage, the problem is when I declare my own class on which they load the file (xml) the code start in the background.I tried to add a listener in the custom class for Event.COMPLETE but it doesn't work because it only affect the custom class, not the whole movie.I tried something like this:
Code:
var xmlLoad: XMLLoadData = new XMLLoadData("navigation.xml");
var menuBox:MenuBox = new MenuBox();

I have this complex XML processing code that builds up thousands of objects on stage. This might take some time. Perhaps not that big time to bring up that message about slow code execution, however signifficant enough to cause interface uncomfortabilities. I understand very well that I can restructure my code in order to save all contextual variables, all counters in an object that is passed down to onEnterFrame events that process it a little bit and then pass it further, until the job is done. However, before I go into dissecting my code, I wanted to make sure if there really is not a way how tom tell flash player do it's frame rendering routine while a complex code is executed in background (without splitting it up).

I want to be able to throw an error to be traced to the trace output window and to my flashlog.txt file but continue code execution after the error. Is this possible in Actionscript 3? A try catch will not work either because I need the error to be logged with its call stack.

I am using a while() loop which does its job as soon as I fetch CDATA content from XML. The while() loop basically contains text conversions using replaceText()... Depending on the number of user defined XML nodes, the while loop executes. I see that the flash application hangs for 3 or 4 seconds when this execution happens.

I have created an image gallery where each "slide" is an image loaded by one UILoader component. Everything works, except I noticed that as a user it is annoying to wait for each new slide to load.So, even with my limited knowledge of AS3, I decided to figure out a way to load the next upcoming image before the user requests itone for odd numbered slides, one for even numbered slides. That way, when the user is viewing a slide with an odd number in the first loader, the next image can be loaded into the second (currently invisible) loader and ready to go when requested button would simply toggle the visibility of these two loaders.
function nextButton(event:MouseEvent):void
{
imageNumber++;

I'm trying this:
- create some asset in library, export for as in frame 1
- export an assets.swc, and set the relative library path publish option in othes flas that use assets.swc
- Then, there's a Main.as document class that uses other classes tha use the assets in assets.swc
Problems start when some asset has some code inside. Say, a button with stopped event states. Well, the stop() commands don't get executed, so the buttons are effectively instantiated, but their timeline plays until the end. Probably because they're not initialized in the timeline (being exported in frame 1, so, in fact, before).Usually, without swc, to solve this problem one would put all assets in frame 2 and then check for cuttentFrame == 3 (http:url...). This is what I'd really like to avoid. And from here the question: is that possible? Is there a way (in flash, not flax) to use swc to properly get assets containing some simple code (usually stop commands) in their timeline?

I have a function that is made up of two main parts (I'll call them A and B). Part B needs to run when part A is fully done with its layout changes. However, there is no "part A is done" signal, and thus I've been calling a validateNow() before part B runs. This works but seems awfully inefficient - was wondering if there are any other tricks to force an immediate measure or something along those lines or if I'm stuck.

The program croaks when measureContentArea (in package mx.containers.utilityClasses, file CanvasLayout.as ) loops through the target's children from 0 to target.numChildren. When the program errors: n == 1, i == 0, and target.numChildren is now 0, when it was 1 before the loop. target.numChildren has changed while the loop is running. It's as if a child was removed by some side effect of calls in the loop.
This happens even when I have many IOComponents on the screen: Here This baffles me because I don't see how I can debug it. I do add and remove and insert children in my game code, but unless ActionScript is threaded I don't see how my code can reach into a loop in CanvasLayout.as .

I'm using a List control. In the renderer of the List control I've got a Repeater. Each Repeater can have a different number of items. Adding to the complexity, one of the components being repeated in the repeater is a Text control that has long text that will wrap, increasing it's height. I need to expand the height of the List completely so that there's no vertical scrollbar. How can I do this?
I tried an extremely dirty attempt at calculating the Lists height based on the data source. From the data source I can figure out the number of repeater items and the number of items in each repeater in the List's renderer. But there's no way to compensate for the wrapping of the text in the Text control.

We have Flex/Java app with a typical scenario:
Clicking the button
Preparing request

I have a textarea where I measure the textWidth and textHeight to make sure the user cannot enter more text than can fit in the text area. I also extended the textArea with a textHeightNow and textWidthNow that measure the textField's dimensions since they update w/out requiring validation. Now this works great for 90% of the embedded fonts I'm using but any fonts that have giant serifs are not measured properly, for instance look at the 'f's in this text area:You can see they get cut off on both sides because textWidth and textWidthNow both return an incorrect size not taking into account the massive serifs.

Visual Studio had a command "showDialog()" which allowed you to show your form as a dialog box on the screen. The advantage to this was that the code calling the dialog box would pause, stopping execution entirely until the dialog box closed. The benefit was you could write your code as follows (made "actionscriptey"):
Code:
var result:DialogResult = form1.showDialog();
if (result == DialogResult.OK)

I am building a Flex and PHP application in which I am providing users a Save results option, which will invoke the php service that generates the results file. I then have the FileReference.download (url) function with the url of the file generated. Problem here is the popup to save comes before the file is even generated in the server. So user will get the incomplete file as the file generation will take atleast 10-15 seconds.
printToFile.token = customerTyped.printToFile(customerArray,displayno);
var filepath:String= "[URL]"+displayno+".txt";
var request:URLRequest = new URLRequest(filepath);
var fileRef:FileReference = new FileReference();
fileRef.download(request);**
I think the function(service) call to PHP function
customerTyped.printToFile(customerArray,displayno);
does not wait for it to return and continues to execute the next statements asynchronously. How do I make the download dialog to wait from popping up until the printToFile php function is completed?

I have been trying to understand the way ActionScript's events are implemented, but I'm stuck.I know that AS is single threaded, which means that only one event handler will be executing at a time, and also means that handlers will be executed in a deterministic order*.For example, consider the following code:
1: var x = {executed: false};
2: foo.addEventListener("execute", function(){ x.executed = true; });
3: foo.dispatchEvent(new Event("execute"));

How do I completely disable the max-execution-time for scripts in flex? The configurable max is 60 seconds, but I'm calling off to other interactive processes which will probably run much longer than that. Is there an easy way to disable the maximum script execution time across my entire application?
