Flash :: Long Polling With URLStream?
Jun 27, 2010I'm trying to open a connection to a URL that will periodically send over a JSON object.

ActionScript 2.0 :: Polling UI GoTo Different Frames?
Dec 23, 2009This is one of those rich media interactive ads, that have the ability to launch another SWF using _root.myPR.openPanel(1); The user has 3 choices identified as option1, option2, option3. I would like to not just openPanel on pr_submitBtn.onRelease, but to have the panel open & advance to a particular frame depending on which option the user chooses in the poll. I have the following launching the panel but not going to different frame labels in the panel launched. All 3 options simply stop on frame "one".
Code:
if (option1 = true) {_root.myPR.openPanel(1, "one");
}
if (option2 = true) {_root.myPR.openPanel(1, "two");

Video :: Overhead Of Using EventListener Versus Polling?
Jun 30, 2011So I have streaming video coming in, and I want to know when it is buffering. This is fundamentally not that hard, just adding an EventListener for some type of buffering event, but I was wondering if this is necessarily the "best" way to do it.
My other thought was setting up a timer that polls the video feed every X milliseconds asking it if the video isBuffering(), or somesuch. While I could, in the worst case, wait the full X milliseconds before querying the video stream, I've decided that this doesn't actually matter to me; I can work around it, and indeed do so quite naturally already.
So I'm asking: is there substantial overhead involved in having an EventListener (assuming I already have quite a few), or is the advantage of catching the buffering event right away sufficiently appealing?
Actionscript 3 :: Memory Leak In Server Polling Presentation App?
Feb 22, 2010I'm building a remote presentation tool in AS3. In a nutshell, one user (the presenter) has access to a "table of contents" HTML page with links for each slide in the presentation, and an arbitrary number of viewers can watch the presentation on another page, which in turn is in the form of a SWF that polls the server every second to ensure that it's on the right slide. Whenever the admin clicks a slide link in the TOC, the database gets updated, and on its next request the presentation swf compares the label of the slide it's currently displaying to the response it got from the server. If the response differs from the current label, the swf scrubs through the timeline until it finds the right frame label; otherwise, it does nothing and waits for the next poll result (a second later).
Each slide consists of a movieclip with its own nested timeline that loops as long as the slide is displayed. There's no actionscript controlling any of the nested movieclips, nor is there any actionscript on the main timeline except the stop();s on each keyframe (each of which is a slide in the presentation).
Everything is built and working perfectly. The only thing that's troubling is that if the presentation swf is open for long enough (say, 20 minutes), the polling starts to have a noticeable effect on the framerate of the movieclips animating on any given slide. That is, every second, there's a noticeable drop in the framerate of the animations that lasts about three-tenths of a second, which is quite noticeable (and hence is a deal-breaker for the whole presentation suite!).
I know that AS3 has issues with memory management, and I've tried to be diligent in my re-use of objects and event listeners. The code itself is dead simple; there's a Timer instance that fires every second, which triggers a new URLRequest to be loaded by a URLLoader. The URLLoader is reused from call to call, while the URLRequest is not (it needs to be initialized with a new cache-killing value each time, retrieved from a call to new Date().time). The only objects instantiated in the entire class are the Timer, the URLLoader, the various URLRequests (which should be garbage-collected), and the only event listeners are on the Timer (added once), the URLLoader (added once), and on the routines that scrub backwards and forwards in the timeline to find the right slide (and they're removed once the correct slide is found).
I've been using mr doob's stats package to monitor memory usage, which definitely grows over time, so there's gotta be a leak somewhere (it grows from ~30 MB initially to > 200 MB after some scrubbing and about 25 minutes of uptime).
ActionScript 3.0 :: Polling With URLLoader Gives Sporadic IoError #2032?
Jul 8, 2008I have a flex app that polls a php script every 1-2 seconds and returns new data. The polling is done with a URLLoader.load call;the requests are HTTP GETs. The app listens for Event.COMPLETE, handles the incoming data, waits for 1 second, then makes another URLLoader.load call.
This process works perfectly for any duration from 4 to 20 minutes. Eventually, a URLLoader.load call fails to return Event.COMPLETE. Instead it hangs for 60 to 180 seconds (depending on which local network I'm using for internet access) and finally returns an ioErrorEvent.IO_ERROR with the message "Error #2032: Stream Error. URL: <mysite.com/foo.php". The app tries to make another URLLoader.load call, but from this point onward, none of the loads return Event.COMPLETE. Also, none of these post-error HTTP GETs appear in the access.log file of my apache (2.0.55) webserver. The app will not work again until I close and reopen the browser.
I've spent several days trying to figure this out! The time until the app crashes appears to be completely random. The problem occurs in both Firefox (2.0.0.15) and IE (7.0.5730.11). I've read that sometimes 2032 errors can be related to caching, but there's no directives (in .htaccess file or httpd.conf file) that sets the Pragma or Cache-Control response header to "no-cache".
I can't tell if the problem is on client or server end. Based on the adobe language references and the forum posts I've read, this seems to be an appropriate use of URLLoader. (In case you're wondering I want the app to respond to events in near real-time. I originally used xmlsocket to push data to app from server. However, this communication is blocked by corporate firewalls, so I need an alternative method)
Here is (cleaned up) code:

View 2 RepliesFlash: Understanding Program Flow?
Mar 9, 2012Specifically, I have a demo of a flash game (sort of super mario style). In it I have two types of weapon - a simple fire and big fireball. I reviewed the code in order to learn flash better [I am very new - since around monday this week].
I saw that the program has a variable that keeps track of the number of uses I have left in each weapon. I tried to review all the places this variable was used but I couldn't find where it affects the drawing onto the screen.
I even tried removing the variable declaration and then testing it - so I may find all references to the variable -- By the way any convinient way of finding all references to a variable/method/class [I am using ADOBE FLASH CS5.5]?
Also, I tried changing the variables starting value to "12" and I noticed that when I test the game, the weapon has 12 uses indeed.
So my problem:1. It seems that this variable is somehow affecting the drawing. Yet, I don't know how it does so since all the code I have found that uses this variable has nothing to do with drawing. It is all, logic, like
if(var <= 0){
var--;
} else{
return false;
}
Where is this influence coming from?get all references to a variable[like in eclipse ctrl+shift+g]?

Which basically causes the movieclips 'leaf1' to shrink, 'vinefade' to go to its first frame, 'artween_mc' to unload, and for all other commands on this button to be disabled. I also want it to check another movieclip called 'leaf9', and see if it's current frame is at less than a particular frame number (73), because if so I want it to start playing forward. Once it reaches this frame number (73), I want to cause linkstween_mc to become visible and hit9button (also a movieclip) to become enabled. My current script does absolutely nothing to leaf9
ActionScript 3.0 :: Understanding Basics Of Random Motion
Apr 15, 2011I started out learning AS3 on my own a while ago without any programming experience whatsoever. I'm still in my diapers, but slowly progressing. Currently I'm working on a short animation with some code involved. Part of the animation is a herd of cows grazing in a pasture. I have a class called Cow which extends MovieClip and on the Cow timeline I have the walk cycle and other cow movements animated. When a cow is walking it slowly moves horizontally, along the x axis. I want the cows, when walking to also randomly move up and down (along the y axis) which would basically look as though the cow is moving further away or moving closer towards us. I'll be resizing each cow, according to its y position to create the effect of perspective (near and far).
What I'm trying to figure out is how to make the cow move either up or down the y axis in a somewhat random way. By "somewhat random" I mean that I don't want the cow to switch directions every second, but rather something like: 5 seconds moving up the y axis, then maybe 8 seconds moving down, then possibly 4 up, then 11 down, etc. It would be super if I could also have a velocity factor involved, meaning that when changing directions - from up to down, or down to up - I prefer that the change is smooth, like as in a ease out and then ease in.

Jan 16, 2010I'm currently reading the book Learning ActionScript 3.0 and have dificulties understanding some programing basics due to my total lack of prior programing knowledge.For example now I'm looking at this script from the book that traces a list of all display objects on the stage and their children:[code]I understand everything except one thing. When there is an object with children (DisplayObjectContainer), the function traces the object but doesn't proceed and calls itself starting all over again this time analyzing the first child of the object. And if the child also have children itself the list will branch out until there is an object without children.What I don't understand is how the function at this point knows how to return to the last parent object and continue to analyzes its other children if any.For example when the function analyzes the stage of a scene with the following content how does the function know to continue analyzing child0. To me, looking at the code, I would expect the function to exit after listing [object StaticText]. I have hard time understanding what makes the function go back to largeContainer and continues with its child0 and so on.[code]This all what the book says regarding this which is not enough for me to understand this process:the function calls itself again. passing in the object currentlybeing inspected. This concept is called recursion. A function calling itself mayseem redundant, but it can be very useful. In this case, each time the functionis called, it receives a new display object to analyze, so the function reportsthe contents of that specific display object. The result is a complete walkthroughof all display objects, no matter how many children each may have.

View 2 RepliesUnderstanding Flash SWC's Imported Into Flex Builder 3 And Key Framed Animation
Mar 25, 2010I am trying to understand what is going on in a SWC that I am importing from Flash CS4 into Flex Builder 3. Specifically I am using a SWC supplied by a Designer as the animation for a custom preloader (a subclassed DownloadProgressBar).The issue I am trying to understand is, once the FlexEvent.INIT_COMPLETE is fired, I cleanup by removing the swc by running this [code]though even after I have removed this (which is successful, as I have checked by comparing this.numChildren before and after the call) the key framed animation still continues to run (not visibly). This has been detected by the Designer placing a trace in the time line of the animation (in Flash). Can anyone tell me why is it, that even after I have removed the animation from the subclassed DownloadProgressBar, it still keeps running ? Also, is it standard practice when importing SWCs to manage the cleanup of resources from the Flash side of things (much like releasing memory in obj-c). I find it counter intuitive that removing the child from the Flex side does not stop the animation.

Jul 28, 2009clarify the different logical instantiations of objects in actionscript?So far it seems there are 3 layers of instantiations, for lack of a better term.The first one is declaring a variable/type.Next is instantiating that variable with something solid in the code, like a method or function? Is this just a way to glue things together? Then after that you instantiate it on the stage, is this something you have to do explicitly, or is it a side effect? Is this "3 layer" concept the correct way of looking at it, kind of like the MVC for flash app logic?

Actionscript 3 :: Simulating A Click Call To A Button(displayObject) Thats Generated Via An API Call?
Nov 2, 2011I'm having trouble simulating a click call to a button(displayObject) thats generated via an API call( youtube as3 API). I have not seen any mention of security reasons as to why I can not simulate a click as long as something is registered with a click handler. Basically I checked to make sure the button made is listening to a mouse click event with:
trace(generatedButton.hasEventListener(MouseEvent.CLICK)) which returns true
I proceed to than call this:
generatedButton.dispatchEvent( new MouseEvent(MouseEvent.CLICK, true) );
And nothing happens yet if I physically click the button it works. Is there some security measure that prevents something from being fake clicked unless its origin is strictly from the system mouse?
I even set a timeout call on the click function and moved my cursor over the button and let it fire in case it was an issue of the mouse having to over the object but still nothing. I am kind of stumped at this point.
