I was trying to get a ballpark idea of how much slower Flash is at pure pixel-pushing 2D graphics than doing the same thing in SDL or other native library. For instance if I have a Flash/Flex app on a modern PC which each frame does a 2D loop and directly reads/sets every pixel, what equivalent PC would give the same performance for a native C++ app? Maybe a classic Pentium, a PII, PIII?

It's a great thing that it's possible to compile an SWF into iOS native app. I think AIR is now the best option to write e.g. small games or interactive books. Of cause AIR app will be slowler than the same app written on e.g. objective C. The question is how slower AIR app will be. Can simple AIR apps be launched e.g.on iPhone 3G or iPAd 1?
And another question is, can arbitrary flash app be compiled into iOS native app?
We are building a flex project and would like it to render faster. We do have situations where we reference parent module size properties to size current module containers, as well as current module size properties for a bunch of attributes including font size and element positions and sizes.
Would it help to create temporary variables for
a) pcw=parentcontainer.width, pch= parentcontainer.height
b) ccw=currentcontainer.width, cch=currentcontainer.height
and reference to pcw,pch,ccw and cch while doing positioning. Also given the bulk of the positioning will be done in mxml, will setting these interim variables in initialization function, allow them to be used in mxml such that they will resize as browser size is changed.
I am new to Flash and ActionScript 3.0 environment. I don't have any knowledge in depth with Flash and ActionScript 3.0. I am using the flash(.swf file) in my Java application.

I am looking for a fairly simple image comparison method in AS3. I have taken an image from a web cam (with no subject) passed it in to bitmap data, then a second image is taken (this time with a subject) to compare this data, from these two images I would like to create a mask from the pixels that match on both bitmaps. I have been scratching my head for a while, and I am not really making any progress. Could any one point me in the right direction for pixel comparison method, something like getPixel32()

View 7 RepliesI'm devloping some library classes for flocking/steering behaviours on large numbers of objects (2000+). I'm finding that at < 500 instances, performance is reasonable. As the numbers increase, framerate bogs down.
I've seen remarkable performance with libraries such as Flint or Box2D with ridiculous #'s of particles / objects, so it should be possible to optimize / refactor my code to be a bit better.
I'm aware of the basic optimizations, such as bitwise operations and optimized for loops. Are there any more fundamental approaches I should be considering? For example, currently each instance is a vector-based MovieClip. Would working with BitmapData be more efficient?
Will I take a big hit in performance using nested ViewStacks? Should I strive to handle all navigation in one ViewStack and push children manually or will the affected performance be negligible?
eg.
<viewstack>
<tabnavigator />
<tabnavigator />
<tabnavigator />
</viewstack>
We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?

View 2 RepliesI am running Flash Professional CS5 (11.0.2.489), updater reports I am up to date. The documentation seems to indicate that FP CS5 should support native custom cursors, but it doesn't (Mouse.registerCursor method is undefined).
Should this be supported in FP CS5? Can I update flash.ui to include support? Is it supported in FPCS5.5?
I'm considering using Flash as the UI of a native Windows app, for several reasons, but before I dive in and start building, I figured I'd poll the community to find out whether anyone's got any good examples of this particular approach out there today, just to prove the concept satisfactorily. So I guess that's pretty much the question: Anyone built one specifically? Or better, anyone know of an app in relatively wide distribution that demonstrates the viability of this approach?
View 4 RepliesAir allows for seamless installs (aka, "badge installs") from the browser, as well as launching an Air app from the browser. Air 2.0 has the Native Process API, which requires packing the app as an .exe/.dmg rather than a .air file. My question: does the badge install process support seamless installation of native Air installers?
View 1 RepliesI recently came to know about the adobe flash builder with flex in latest release it supports to achieve the benefits of flash for iOS apps.As i am looking for a calendar based app,before taking the Adobe flash builder as a solution, i would like to be clear on the following queries.
What limitation is there of the ipa file generated from FB 4.5 as opposed to a core COCOA touch based solution What are the performance differences between the FlashBuilder app and natively built iPhone app. Is there any limitation of building a HTML5 based app given the calendar functionality apart from look and Feel.

View 1 RepliesI have a Facebook application where you can create an animation and share it on your wall. Each feed has a swf player that lets users to play the animation directly on the wall. (like any shared video). As IOS does not support flash, I have also created a native IOS application for playing those animations.
These posts can't be played on IOS devices, when touched, 'Flash Player update required' placeholder is shown.
What I want to do is, to have an alternative link for iPads to play these feeds on my native IOS app (like fb://APP_ID/video_url).
Is it possible to provide a native IOS App url for inline swf feeds?
I'm looking for an alternative to native Flash components. They are way to heavy for my needs. I'm looking for something light, simple, still customizable if possible for AS3. I'm specifically looking for combobox, checkbox, radio button.I'm looking for something reliable with support eventually...so basically I'm ready to pay the price of a good alternative.
View 1 RepliesI am trying to do an app that requires me to change the behavior of a few native methods and classes of a an application.I want to override methods such as:ExternalInterface.call, ExternalInterface.addCallback, flash.net.navigateToURL in a loaded movie.There are a few ways to do this for example:1. Getting the SWF's bytecode and decompile it. Then change the symbols table with my own class.2. Loading the other movie in my applicationDomain, by doing so, I would be able to rewrite it's own classes.o do (2) what I did was:1. Turn off the "-strict" flag.2.

writing the title in question in www motors of search u can read a lot of comments on the novelties introduced with the new releases of the flex sdk [URL] where is used the new class MouseCursorData present in Flash.ui libraries.

I have to implement AEC in Flex video conferencing application. I know that it can not be done directly in Flash. I'm thinking to write a native application or library that will do AEC outside Flex.
As far I know Adobe Connect Pro is using some external library that do AEC. I'd like to follow this direction and do something similiar.
There comes two possibilities in my mind:
1) Independend custom AEC filter.
The custom AEC filter will be run in the background and will be processing all data from microphone and sound card and doing AEC. The echo signal will be the data that is to be played but delayed in a temporary buffer, something like this: aec(input, delayed_input, output).
I don't know if it work, because Flash microphone input doesn't know about my custom input and the same with the speakers. But how it is done in WinXP/Vista that have AEC at the system level?
2) AEC filter interacting with Flex's NativeProcess.
The filter will be run by NativeProcess. Flex app will pass microphone sound, received remote voice to the filter and return voice with echo removed and then Flex will output this to the speakers. Will it be correct?
If the 2) method is OK then I have following questions:
I will start with Speex's AEC so in what format should be the data pased from Flex? If I choose Flex Speex codec for sound compression can I pass it directly to the speex library? Will be the performance OK? Calling NativeProcess library every sound frame buffer can be time consuming I think. Why there is no AEC implementation in AS3 that can be used directly from Flash? As far I know to do AEC you must have echo data and microphone data (in Flash 10 there is direct access to the microphone). There is definetly something that is stopping doing it like this but I don't know what it is yet :) Is there some free AEC implementation or a DSP library with in except Speex's that I can use?

I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.

So I just found out the hard way that the path that Flash uses to load external content is based on the HTML it is embedded in, not the SWF itself. This is a problem for me because I have the HTML generated from a PHP file that is in a folder below the SWF. The PHP has other dependencies that would break if I moved it into the same folder as the SWF.So basically now my dev testing and web versions are separated by a folder.Is there a way to change the relative path Flash uses? Or am I going to have to hack things up?

I have also gone into Flash and can change the h-link of the TEXT on the button to the corresponding page, but it makes no changes whatsoever.
