Does anyone know if strong typing variables in Flash does in fact increase performance? I've read and heard both versions.Also, is there a way to strong type a variable that you set this way:[code]

View 4 RepliesSo, performance wise, is it necessary to null references to classes, etc inside a function? Something like:
Code:
function myFunction():void{
var myVar:myClass = new myClass();
//do stuff with myVar...
//don't need myVar anymore
myVar = null; //is this necessary?
}

I'm currently making a game to educate children. The game is a recycling game and when they collect more then 5 items a random fact will appear. So far these are the facts I have used...
var b = new Array()
b.push ("Glass can be recycled virtually forever. It never wears out.")
b.push ("Most bottles and jars that you use contain at least 25% recycled material.")
b.push ("The energy saved by recycled just one bottle could light a 100-watt bulb for 4 hours.")
b.push ("Paper made from recycled paper uses 70% less energy.")
b.push ("98 tons of various resources are required to make one ton of paper.")
b.push ("75% of each tree that is cut down for paper is not used in a paper product.")
b.push ("We get through nearly 3 billion disposable nappies each year in the UK alone and around 90% of these end up on landfill sites. Disposable nappies take 500 years to decompose.")
b.push ("Every tonne of paper recycled saves 17 trees.")
How I can make them show up randomly 1 at a time.
I have a working Flash mailform that is pointing to Comcast's form created when a generic website is built. When that generic form is used in html format a confirmation page pops up with a standard "Thank You, etc.". I have a Flash thank you page built as well but it has nothing to do with what is going on on the server since I don't know how to connect these two. So in case there is an error on the server's side Flash will not detect it and the user will think his e-mail went through. Is there a way of writing a code that would take care or of it? The html address of the form that I'm addressing with Flash and the "Thank You" page is the same - just the contest changes. And here's the source for the latter (not much to it but what is VLINK or LINK - they seem to be the only unique things in this code?

I have a class which will contain exactly one child, no more, no less, and other classes are not allowed to change that fact.
I could throw error messages every time a child is added or removed by overriding the default properties, but I don't want the object to be treated as if it were a DisplayObjectContainer.
I want it to look like only a DisplayObject, yet I still want to add a child to it in private.
I am playing a video and created a button which displays video area in fullscreen but video doesn't cover whole screen area, there are blanks left and right of the video. I searched a bit and every flash player i found with full screen option in fact resizes the video the same way, it just doesn't cover whole area. Can video in full screen mode be resized to cover whole screen area without those blanks at sides?
View 5 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 3 Replieshow can I increase the size of flash CS4 interface? Meaning also to enlarge tools buttons, so they are easier to see. I have to strain my eyes, because all of the toolbars and text related to them are too small, for constant work.Is this possible? I know there is one way - to increase display DPI settings, but that would also increase the whole desktop, but I would like just to increase flash interface text size and if it is possible then also tool buttons.
View 1 RepliesI am making a side scrolling flash game. The level is pre-made so there arent objects wich spawn on runtime. Now I made this level quite long, but in the editor window it suddenly stops. But in game it still scrolls on.This is in the editor.You can see that the scroll bar cant go left any more.The level is longer than then shown in editor. At first it was just putting an object at the border of the scene to increase it.

View 1 Repliesi have created an animation (kind of tween) in flash by AS,i want to use it more than once in my project, but CPU usage increase very much!i think save my animate as swf and load it in my project.
View 2 RepliesPowerMac Dual 2.3 GHz G5/8 GB RAM I suspect I'm not using best practices, as this is my first project, but my the flash file is getting very sluggish to work on. The swf (AS 2.0) publishes fine and runs OK off the server and in the browser, but the Flash application is slowing down to a crawl making work very unpleasant indeed. Not that it was ever that fast to begin with. The Flash file size is presently 15 megs. It's got a log of symbols in the library and a lot of small jpgs used as navigational buttons, and utilizes many instances of the loader component to dynamically load external files: Is this too much of a demand on the app's resources? I do think that some of this has to do with a poorly implemented user interface (first attempt by Adobe to make Flash "look and feel" like a CS app), but I'm sure there are other issues.
View 1 Replieshow to increase the work area of a flash document? Not the stage but the empty space around the stage. [URL] It seems to be limited to about 4,000 pixels wide regardless of the zoom level. This is a big problem for me as I'm working with a movie clip with a width of 8000 pixels and if I want to add text to part of the clip that's at 6,000 pixels in, I can't see it because its outside the work area. I can't shift the clip to the left to access the part on the right because if I do, the text area doesn't move with it. Is there any way to link objects together? When I select multiple items on the stage and Right Click, there's an option called "Break Apart" but I don't see one to join them or link them.

View 2 RepliesI have a small question about the size of images imported to flash.Recently I imported a series of png images to flash CS5 to be used in an animation, 92 images to be exact. Each image was 34Kb size. Before I imported the images, the FLA was 6kb, and after I imported them the FLA was 160 MB large. Now 33Kb * 92 isn't 160 MB, so why does this happen? Is there any way to decrease the image quality or something when importing, or do I have to do that manually when creating the images?
(I used photoshop, and the images have a transparent background if that makes a difference).
I need to make a counter that will increase with 9 every second
starting point at = 1440836946
Another thing is that I need it to save the the result to view when next time.
I was wondering, because people do suggest this, but i've never explicitly had it verified:does the flash cs4 compiler actually generate a SWF file, that is more optimized and faster, than the flash cs3 compiler?and what about other compilers? custom as3 compilers, are there faster ones?I don't mean the time it takes to compile the .fla, but the speed of the SWF file.
View 1 RepliesI've been working on simple animation for a client, which you can see __here__.I have a few issues with performance. I have popped a fps counter at the top left and it seems to only run at around 30 fps on my laptop, I need it up to 60 though.
i was just wondering if anyone had any tips about getting the best performance from flash.I have used Shape instead of Sprite on the curves, which gave a slight improvement. Surprisingly I didnt notice any change in performance when I dont use the blur filter on the curves, which was odd to me.
Steps to reproduce my problem:Create simple dot DisplayObject in flash
dot.graphics.beginFill( color);
dot.graphics.drawCircle( 0, 0, 2 );
dot.graphics.endFill();
Draw dot to bitmap many times a frame
bitmapData.draw( dot, null, null, "normal", null, _smoothing );
Test FrameRate in combination of browsers,flash plugin versions on Win32
Expect:
Framerate to be close in most cases
Observed:
I am seeing a 25% decrease in framerate under IE7 using Flash10b.ocx(10.0.22) and 50% decrease in framerate using Flash10c.ocx(10.0.32). PLugins under FireFox, Safari and in Mac OSX don't exhibit the same slowdown.
I would like to get help/confirmation on a performance problem that I see in Internet Explorer. The Adobe and Flash community is great on the Internet but I have been surprised to see no information on this, just a few reports about movie playback on 10.0.32 vs. 10.0.22.
My guess is that in IE flash plugin is passing draw calls to Win32 and that this is slow.
Instead of drawing each time on the bitmap using draw, cache the draw calls to a bitmap and use CopyPixels. When I do this the performance is the same across browsers, within 10%.
bitmapData.copyPixels(dot.bitmapData,dot.bi tmapData.rect,new Point(dot.x,dot.y),null,null,true);
Loop I am using:
function enterFrame(e:Event) {
bitmap.lock();
for (var i:int=0;i<particles.length;i++) {

I'm a developer on nice space MMO using Flash. On new PCs performance is quite good, but some features shouldn't be enabled on older PCs because the framerate drops to shit if we do. Flash wasn't made for this, but hey, pushing boundaries is fun.
An example is fullscreen mode. Of course every user can manually enable it, but "advertising" it to a user with and oldie PC would be a bad idea - but for the Alienware crowd it would be dumb not to.
So I want to find out how "capable" a user's PC is to decide if I should enable or disable some features for him.
Well I'm having a hell of a time trying to get my CPU down under 45% when running my current application. I've tried all sorts of optimization tricks and tips with little success and I'm at a point now where I need a fundamentally different approach.
Problem and Current Approach In the main view of my application I have a single enterframe handler.I have my frame rate down as low as 10 fps. This handler notifies 16 seperate movie clips to draw wedges of varying angles using Lee Brimelow's wedge class. So, 16 times every enterframe, I have 16 movieclip graphic clear, begin fill, draw wedge, endfill all being co-ordinated by my single enterframe handler.
