I'm working on a project which has some CPU performance issues, mostly from rendering items that are somewhat transparent.Looks great on fast machines, but gets dogged down on slower machines. Does anyone have any good methods for ways to detect if the app is slowing down on the client machine? If I could detect this I could tailor the elements a bit to improve performance on older machines.
View 1 RepliesI have some shared code between an Adobe AIR App and an Adobe Flex App.
On one line of this code, the program must behave differently depending on if it is running within the Air runtime, or the Flex runtime.
How can I programmatically detect the difference?
this is what i'm trying to accomplish; With a click on a movieclip (cannon_mc)a shot is being fired (ball_mc)
The longer mouse is down, the speed of wich the ball is fired with should increase.My question to you is;
What is the most efficient way to accomplish this? With a timer or something like this;

I'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 1 RepliesThe stand-alone Flash player has an option to print a SWF. However, there is no shell action registered for this, and as far as I can see the only way to do it is to use a keyboard macro (or do something invasive such as inject a DLL in the player). Is there some official API for this?
View 1 RepliesI was wondering how I could programmatically create a swf using Flash AS3 and AIR? I have successfully recreated a swf (using the data found in a swf file converted to hex and using byteArray) but I can't seem to change anything to it; if I do it no longer works.I have some text fields a person can enter information into. I want to take that information and save it out to a swf file.[code]

I have a flash file. I have a class called Screen. In Screen I want three properties: Image1, Image2, Image3. These image properties are representative of three bitmaps already in my flash file. How do I just create instances of them? And once they are initialised what type are they? Are they BitmapData?Or I can put said images as graphics in my flash file, so how to I create an instance of a graphic programtically?If I can't do this, I am happy to load the images from an external folder. How could I do this? Is it just load("image.png")?
I want to be able to just pass as a parameter the image instance and screen holds a reference to it. How can I create this instance though in the first place?

View 5 RepliesI am trying to programmatically queue MovieClips on the scene to play one after the other.

View 4 RepliesI am developing PDF to e-book converter which will run on a server.I need to programmatically extract embedded fonts from PDF file to finish the project.Now I am able to extract images and text, but to display content in the Flash Player precisely I need the fonts to be extracted from PDF and compiled to SWF to be loaded by Flex application at run time.
I am wondering if it's possible, as such tool as pdf2swf.exe from SWFTools is able to do this. I have decompiled the swf file produced by the tool and there were fonts embedded.The extracted fonts will be used for displaying the same content from PDF file only, just in Flash player. So i think it will not be any rights violation? Moreover, people who will use the converter have all rights for the PDF files content.
So I see next workflow:
1. Call pdf2swf.exe to produce SWF file with fonts embedded;
2. Call some tool (Which one?) to parse previous SWF to SWFs with separate fonts.
3. Load the SWFs with fonts to Flex application at run time to correctly display content.
I need to load several images as Bitmap or BitmapData objects. The images are hosted outside the Flex project, and they're referenced by an external configuration file, so I can't embed them. Because the images won't be displayed directly to the user (they're being added to a PDF that is generated for download), creating a grouping of Image objects, attaching them to the application, and waiting for their LoadComplete handler to fire seems inefficient.
What is the best way to load these images into an application? Programatically load images in it?

View 1 RepliesI would like to know the correct way to close an AIR application programmatically. In my Spark WindowedApplication I have:this.addEventListener( Event.CLOSING, shutdownApp );and of course an implementation of the shutdownApp method (which basically tidies up temporary files).his works fine for the top-right close button of the window. However I also have functionality which needs to shutdown the application. Within the code I have called:NativeApplication.nativeApplication.exit();However this doesn't trigger the Event.CLOSING method, and so my temporary files are not cleared up. Should I not be calling nativeApplication.exit ? If so, what should I call instead? I'd rather not have to call my shutdownApp method before the NativeApplication.exit() as this doesn't feel quite so elegant.

I have various components that are skinned through a programmatic skin. The skin class references a singleton class that holds various colors to be applied to different aspects of the component. The singleton class has default colors set to variations of black/grey etc. I'm loading in custom colors from an XML file that are then loaded into the singleton. I'm applying the custom skin through a css stylesheet that is included in the main Application mxml.
The problem is that when the swf initially loads, the components that are drawn on screen are black and don't reflect the changes in color loaded from the XML file. I have some dropdown windows that show on button clicks and those dropdowns do reflect the correct colors from the XML file. Therefore, the system is working correctly, but the initial drawing of components obviously happens before the XML is loaded and applied to the singleton.
My question is, is there a way to apply a skin to an element programmatically by calling the constructor?
I have this in my css file:
.PanControlsBackground {
borderSkin:ClassReference('skins.buttons.PanControlsBackground');
}
[Code]....
or something to that effect? This way, I can remove the loading of the skins in the css file and control when they are instantiated to ensure that the correct colors are applied before displaying the various components.
