when I have a movieclip that gets to the end of its playhead and calls the stop() command, the framerate drops from 24 to about 16. This movieclip contains other movieclips that continue their animations. I assumed with one less timeline running the performance would actually increase. There is no other code running, just a movieclip containing other movieclips that suddenly slows when it hits stop().
View 2 RepliesI have FMS 4 and a videochat app (one-to-one), everything runs smoothly until about 750 users (it means about 1500 connections to fms), then I get a sudden drop in users connected to 300-400, no errors in the fms log and the cpu/memory usage is at about 25% just before this. I'm running Windows 2008 R2 Web (x64) and I've red somewhere that maybe this version of windows has some connection limit that could be the cause, but I've no idea of what could be happening.
View 2 RepliesWe have an AIR application running on an Apple iPad, that occasionally experiences sudden drop in its performance. The frame rate drops from 60fps to 2fps and it never recovers from that. this is only reproducible on iOS 4, but never on iOS 5 - we've checked that on two identical iPads (generation 1)the performance drops occasionally, but always happens when we switch between apps - from our app to another and back very rarely, the performance drop also happens on first start of the app this performance issue does not happen in renderMode=CPU, but this mode doesn't work for us, because the rendering is ugly, especially on rotated bitmaps.
View 1 RepliesI'm currently trying to make a little game but I experience now some loss of framerate while adding "bullets" in the gameI'll not enter in the full code source as it will take some time but basicallyI got a mainGame class, a Player class, and a bulletClassthe mainGame class contain the game loop working like this, main timer cecks:-loop function of the Player class, checking if space is pressed,if it's pressed a bullet is displayed with this line in the player class:Code://main_class is the MainGame class and the container is the main displaymain_class.container.addChild(new Bullet(x, y, otation,main_class));//then the bullet add itself in a _bulletArray of the Main Gam class-loop function of the bullet Class, for each bullet cointained in the _bulletArray,it moves the bullet from some X, and if it's out of view of the screen it destroying itself from the array and with a removeChild of the display list like this:
Code:
y += vy;
x += vx;

So there's been a new "feature" in the flash player since version 10.1, which reduces the player's framerate to 2 fps when the application window is out of view. This is good news for performance, but it can break some functionality, such as the Timer class.
I have an application which uses a Timer to display a countdown. Given the nature of the application, it is required for the Timer to complete its countdown even if the user is not there to see it. Imagine that you need to give the user only 10 seconds to perform a task. If the user minimizes the window halfway through the counter, they can take as much time as they want and still have 5 seconds left when they return to the window. This apparently can not be avoided with the newer flash players.
In Air applications there is the backgroundFrameRate property which can be set to prevent this behavior, but this is part of the WindowedApplication class, so it seems that it is not available in a web application. Does anyone know a way to keep a constant frame rate even when the window is not visible?

View 6 RepliesI am currently trying to port a game that I wrote in as2 to use as3. Most of my code is divided into classes but my art and buttons are placed on the time line and divided into different scenes.Now getting access to these objects are no problem. I just wait for a render event and then I get their reference by using getChild from the root object. Now my problem is that when I change scenes the game suddenly speeds up and run really fast for some time and then goes back to normal.My first experience with this problem was when I added a skip button to my game intro.since I didn't stop it but simply chanced scene it went on playing in the "background" as I could still hear the sounds from it. now when I entered the new scene every animation ran twice as fast or even faster and it stopped once my intro finished in the "background" or wherever it was . I solved the problem by simply stopping all animations before changing scene and thought that was the solution, but I soon discovered that, that didn't work at some places.
When I had made the menu scene working and started moving between some other scenes without animations but with lots of movie clips the problem reappeared. I tried to track my problem down to some move clips and I sort of did find some that I could remove to solve my problem but these clips only contained one frame and had text in em so there was no animations to stop. Also the speedup got pretty random, sometimes I got lucky and the speedup didn't happen but most of the times they did.Now my question is why are these speedups happening, and how do I prevent them?I have been thought about copying everything on each scene into a movieclip and then add and remove those clips to stage, and when I change scenes.
I've changed nothing that I know of in making flash slideshows using swish and exporting to .swf format for inclusion in Dreamweaver except that now all of a sudden the flash item has a white background -- but only on my computer it seems when testing online; locally, it doesn't do that when testing and when using a different computer it doesn't do that. Any idea why a flash item would have a white background in some cases and not in others like that?
Like I said, I've changed nothing and have never had to put any parameters in place or do anything else of the kind; the swish program itself specifies the background as red, not transparent (not that the page the flash item is on has a white page anyway). I don't know if this is a swish, flash, dreamweaver problem or some bug on my particular computer that I can't figure out.
I have a CSS drop-down menu and just below is a Flash Video (embeded with YouTube code). The Flash video covers my drop down, but only in Safari.
I have played around with the z-index, and I have tried both "opaque" and "transparent" for wmode (which has always fixed this for me in the past).
how to stop the video from covering my drop-downs?
Is there anything else besides high cpu usage that would cause the framerate of a swf to lag?I'm working on a game that is set to 60fps so the animations are super smooth, and I am on good, fast computer so even with tons of animations going my cpu usage never goes above 14% usage, and only about 1% of the systems memory is used.
View 4 Replieshow to set the FrameRate (fps) using action script?
View 2 Repliesi am making a flex air application and when its deactivated (lost focus), its framerate becomes to 1fps.i am using psudo-threading encoder that uses enterframe to keep it working the app requires long time converting process more than hours and i need the program to do the same thing while sitting back in the background how to disable deactivation in air application as soon as the focus is out, it becomes 1 fps instead of 24 fps which i need.
i know i can use timerevent rather than enterframe event but my app needs alot of calculation and i figured that in flash, the frame extends its time if the calculation isnt finished. if it gets too long in one frame, the ui hangs up.if i use enterframe, on slow comps it would extend its time to complete the calculations when all the calculations didnt get to finish in time in 1 frame.but im afraid if i use timer event, instead of waiting for the codees to be excuted it would excute the next timer event, i didnt try it though.i created the app that when you add the xml songbook data, it would load up the data sort it and create pages with the graphics and skins set up and when you save, it saves the pages to jpg files using the encoder i created.and the encoder uses enterframe.its working fine but when i deactivate the window while encoding, it becomes extremely slow since it becomes 1fps.
Every now and then I come across some examples on the web that have a nifty little FPS output window. I have also seen a couple that count objects on screen and various other usefull data.Rather than build one myself since I am pressed for time on my current project, does anyone know where I could find a little class or component like this? I had a link from a friend pointing me to one, but I lost the email when I migrated to a new machine (yes, I should have migrated my mail data file - STUPID STUPID ME!).

View 1 RepliesTo cut a long story short, i'm learning flash in order to get a job in 2d interface design. I had some basic knowledge of the software prior to this, but i needed to further my animation to compliment my design skills, so bear in mind that this is my first major flash project. So far, everything was going well, and i was managing to achieve my vision so to speak, but i have hit a brick wall with this problem. The interface starts with three menu options, single player, multiplayer & settings; each staggered behind and to the right of the last. However the transition i have made between them (basic motion tween with blur filters changing slightly) stutters everytime.
I have uploaded the animation here so you can see for yourself. Also, here is a screenshot of the timeline for the first transition: It does it a little bit in the scaled down version, but if you view it full screen it really slows down. Also, if anyone can be bothered to wait through the slow stuff to see the animation that works
I have an AS3 App class e.g (pseudo code)

}
}
and this is then extended by the app MXML:

The app appears to be running at the right speed, but in MyApp.onRender(), frameRate is seen as NaN (in the debugger too if I step through). Why is this? How should I be obtaining the application's FPS property?
I'm developing an AIR app that is receiving TUIO events from a Framework for a fiducial marker based multitouch table. Until yesterday I was faking the events by mouse to work faster, but then I connected everything to a TUIO simulator and the problems appeared.
The TUIO Simulator is a java app. By dragging markers on the simulator you can send OSC messages that I'm forwarding to my AIR app. The problem is that I'm noticing that when I drag something on the simulator, my AIR app lose the focus, and the AIR framerate suddendly drops. If I drag something on my simulator and I switch super fast to the AIR window, everything goes smooth, so it seems the problem is that if my AIR app is not the active app it's redrawn at a lower framerate (I remember reading something about this, not sure).
So my questions are: am I right about the fact that inactive windows in AIR are redrawn at lower framerate? do you have any workaround to fix it and to allow me to interactive with the java app without my AIR framerate drops?
However, there is one issue that plagues a lot of viewers, their players not being able to rend the frames in time.Flash rends each frame on the spot where it is needed, this is obviously needed for actionscripting and similar. But this also means that if a frame takes too long to rend, the player has to do something about it.
The player actually does one of two things, depending on if there is any streaming sounds going on or not.If there is a streaming sound, Flash drops frames to keep in sync. Otherwise, Flash just ignores the issue and draws the next frame as if it didn't have any lag detection.Obviously, neither of these is desirable. What can you do about it? Well, the obvious thing is to not do crazy graphics that takes forever to rend. But what if you can't change the graphics?
There is one thing that you can always do, change the antialiasing level the player is using to do the rending. It's 4x4 (High), 2x2 (Medium) or none at all (Low). This makes the rendering go faster, since it is rendering to less pixels.You can also do other things that are movie dependent to reduce the work load. Things like spawning less particles in a particle effect or outright not having some effects. But those are all movie specific and difficult to work with in a general way.
One idea that I had was to draw everything to a bitmapdata of a smaller size and showing that instead, however, that has it's own issues. For one thing, I do not believe that the player can do it's "changed only" redrawing when you do this. Second, there is the issue if you want the corresponding bitmap instance to be smoothed or not. And of course, if you do this, zooming in will not have the infinite resolution that Flash is known for.Obviously, you need to know when the movie is lagging in order to know when to do this. However, the best I can think of is timing the enterframe events and checking if it has been too long since the last one.
This works to show if you are having issues reaching the target framerate or not, but it does not show the load if you are not having trouble reaching the target framerate.
Now, assuming that we have a metric for how well the playback is working, the big question remains: when do you change the rendering settings? And how do you do it?Yes, it is just a simple property of the Stage class for the antialiasing, but that is not what I mean here. I mean, how do you say if it should be changed or not? When it's even lagging one frame? When it's not lagging for one frame? The same, but for 20 frames? This is something I don't know what to pick.
There's this flash web page Im developing. All movement is 90% written in code (as oppose to it being created via designer mode). And for some reason the frame rate of page in browser just keeps dropping. Can someone tell me what that reason could be?I am aware of the fact that framerate does change from time to time but I think that after a while it should climb back up. But in my case it just keeps dropping (by the 9000. frame its like 2 fps) and there isnt memory leak cos used memory amout by browser stays the same
