I need to create a internet speed test application in Actionscript 3.0, like Speed Test. I need to calculate:
1. Download speed
2. Upload speed
3. Latency (Round Trip Time)
4. Jitter
5. Packet loss
6. Network availability
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;

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++) {

Specifically, I want to test exactly how many connections my installed version of FMS can accept.
Is there such a tool for benchmarking with FMS?
I need a meter that shows the current bandwidth rate as a percentage. For example: The maximum bandwidth rate is 4mbps, the current bandwidth is 3mbps, so the bar would be 75% full. This bar would change dynamically as the bandwidth rate changes.
View 9 RepliesI'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.
i am pretty familiar with tweaking as1/as2 performancehowever in as3 i am still a noob concerning optimization.i tend to have a class utils in my projects in which i carry a lot of static vars and functions.[code]
View 3 RepliesI'm building an air app which will run on iPads. For the touch interaction I'm using just MouseEvents handlers (MOUSE_DOWN, MOUSE_MOVE, MOUSE_OUT, MOUSE_UP) because my app don't need multitouch, now I'm wondering if there is any difference in execution speed, should I use the equivalent touch events or the mouse events are faster?

View 3 RepliesI'm creating a stand-alone player based Flash app. Some of the required elements within it are links to areas in a site online. I need to test before hand if the user has a connection. I'm stumped on this one. I'm not worried about NetConnection etc. I'm simply trying to test if the user has an internet connection or not. Would anybody happen to know if there is a function or some combination of methods that is not browser-based that can test for an internet connection?
View 2 RepliesI need to create a basic speed test for a website I'm putting together, but my flash is a little rusty.
View 1 RepliesI have 4 animations and based on the speed of the internet i want it to change between each depending on the speed.
e.g...
0 - 10kb/ps - 1st MC
11 - 30kb/ps - 2nd MC
31 - 50kb/ps - 3rd MC
50+ - 4th MC
My idea is to have like a glass of water... and for the 1st MC the water filling it up is only a drip... and then 2nd MC is a slow stream of water etc etc and then final MC is water gushing in filling the cup up faster until it's full...
I think this might be a bit hard for me... as i can't even make a preloader... everytime i try the SWF file just stays blank until it's fully loaded... haha... but i'll read tutorials and stuff... i'm rather basic with Flash and just learn what i need to learn as i get to it... I also need the transition between each change (say from 1-10kbps - 51+) to be smooth rather than just having it going from a drip to gushing water... but i think i'll just have to make animations for each and then IF statements to deal with that issue..
On the PHP site it was advised to do for loops in a certain way that I have not seen on any recommendations for AS3. I think I found about a 10 times speed increase and I thought I better check that I was not missing something (?) before going through my code and changing it. Very simple and fairly self explanatory (in the faster one the array.length is not calculated every time I think):
Code:
import flash.utils.getTimer;
var time:Number;
var myarray:Array = new Array();
myarray.length=2000000;
time=getTimer();

I am developing an application which is similar to[URL].. I need your advice on how to achive the ping and download and upload speeds. I have experience in as3, but very new to this kind of applications. can you please give your thoughts on how this application is developed.
I assume the application needs to download a file, based on the data loaded in that specific time we calculate the download speed. i am not sure about the upload and the ping.
I need to test the upload speed of the client machine in AS 3.0. So I thought to upload an image that embed to swf, to server without user interaction.
View 2 RepliesI get a working application in Flash made that lets the user click to create blocks which subsequently gravitate towards the mouse. I made the exact same thing in Processing too, just to compare speeds.However, when I run the Flash version and add around 15-20 blocks, the framerate drops to 5-10 FPS.In the Processing version I can add ~60 with no noticeable slowdown. What's the deal, Flash?
Links to each version's source:
Flash version
Processing version
Here is the source for each in case you are a wizard and can help just by glowering at the code sternly and telling it to behave:

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 4 RepliesI want to add an animated .gif file to my movie. So I created a new symbol and then imported the .gif file to the stage. This created the symbol containing the animated .gif.I dragged the symbol onto the scene where I want it. However, the animation seems to play at a different speed (fps) than normal. So I changed the fps of the symbol (at bottom of Timeline where it says "fps"). But for some reason this changes the fps of the rest of the entire movie.
View 3 RepliesI'm tweening a movieclip from startX to finishX. The value of startX varies but finishX is a constant. But as the startX increases in value the animation appears to be quicker. How do I adjust the speed of the tween to ensure a consistant speed regardless of the value of startX?

View 2 RepliesI have a movie clip on my scene which has a speed applied to it making it move across the screen. This is duplicated when it reaches the other end of the screen.On my scene I have some action script which is acting as a timer. After a set time I want it to increase the speed of the movie clips, making the game become "harder". I seem to be able to manipulate the alpha of my movie clips but can't seem to trigger the speed increase.If i use a setInterval it seems to trigger the speed increase but it does it each time the movie clip is duplicated (so the delay resets, it does not change once and apply throughout)However, where I am changing the alpha I cannot seem to change the speed.

View 9 RepliesI'm trying to test a custom Flex 4 skinnable component, using the FlexUnit UIImpersonator class. If I run my tests from a FlashBuilder Spark only project everything works fine. If I try to test from a project with the mx component set on the classpath I get a "getElementIndex not available in non Flex 4 projects" error.Can I unit test spark components in FlexUnits visual test environment while still having the mx component set on the classpath?
UIImpersonator delegates it's method calls to a "testEnvironment".The implementation used for this "testEnvironment" is decided by the VisualTest EnvironmentBuilder class and the FlexEnvironmentBuilder class. If the FlexEnvironmentBuilder class can find the "mx.core.Container" on the classpath it returns a MX environment, else a Spark environment. Only the spark environment has valid implementations for Flex 4 relevant method calls on the UIImpersonator - like the addElement method.
My buttons only work when I click on them on the stage while having the "enable simple buttons" option on. They do not work if I try to "test movie," "test scene" and publish it to a SWF. Nothing responds whenever I am in these modes. I am using Adobe Flash Professional CS5 Actionscript 2.0.
This is the code that I put in for the buttons:
