The problem is, the framerate is not constant, meaning it goes out of sync with the music very often.[code]...
Can I get flash to maybe skip or drop frames to make sure it keeps an overall steady framerate?
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.

how to set the FrameRate (fps) using action script?
View 2 RepliesI have an AS3 App class e.g (pseudo code)

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 loading some external SWF's and want to see what framerate the loaded SWF have. However, all of the data tells me the root SWF's framerate.

My Flash game targets 24 fps, but slows to 10 on slower machines. This is fine, except Flash decides to throttle the queue of incoming MouseEvent and KeyboardEvents, and they stack up and the Events fall behind. Way behind. It's so bad that, at 10 fps, if I spam the Mouse and Keyboard for a few seconds not much happens, then, after I stop, the game seems to play itself for the next 5 seconds as the Events trickle in. Spooky, I know.
Does anyone know a way around this? I basically need to say to Flash, "I know you think we're falling behind, but throttling the input events won't help. Give them to me as soon as you get them, please."
Simply put, I am making a flash midi player. I am using ENTER_FRAME for my timings. I set the framerate to 100 to ensure that the timing of each note in milliseconds is accurate. When I test the movie with CTRL + ENTER it works fine. When I publish it and open it in a browser (tested both IE and Chrome), it suddenly plays back a lot slower. I don't think it's a performance issue, since the code is very simple. If this slowdown is consistent then I can perhaps work with it so that the playback speed will be correct. Do browsers make the framerate slower or do they implement a framerate cap of some sort? What is going on?
View 2 RepliesI'm creating an ActionScript-based flash file that only needs the screen to be updated in response to something happening behind the scenes. As such, I don't need it to run with a fixed frame-rate. Instead I just want to tell it to lay dormant until I explicitly tell it the screen needs to update.However, I don't see any way to do that. Can that be done? (i.e. set the framerate to zero and manually force an update based on some user-defined event?)For example's sake, if you can provide an example that just kicks off the update based on a simple timer,

View 4 RepliesI'm trying to create a method of saving data to disk in Flash.
Uploading the data to a PHP server works... well enough I guess. The issue is that when I go to reload the data, the file has been cached, and so I can't load the saved changes.
Is there a way to force flash to reload a file? Or clear it's current cached version?
How do you force Flash to refresh its xml data?
I have a Flash app that uploads an xml file using URLLoader() and URLRequest(). But this file gets overwritten every 10-30 minutes with fresh data. The only way I've found so far to view changes in the xml data is to refresh my web page (F5 or Ctrl-->F5). Short of turning to Javascript, isn't there some way for Flash to refresh its xml data?

I have a section of code that starts with creating a new NetConnection and then streaming a media file from an external source.

Yesterday when playing a game (Balloons Tower Defense 3) I noticed that the game started to slow down over time and then randomly speed up very quickly. Looking at the memory usage dropping each time I assumed it was the GC running.
As a legitimate question, is there anyway to force Flash to GC from, say, Firefox? Perhaps there's an addon or a command you can run that will do this? I know that you can do System.gc() but this game isn't mine so I can't modify the source with a "Click here to GC" button.

I am creating a web site using Flash CS3 actionscript 2.0.I know how to but the one extra thing I need to do for this site is create a button that anyone looking at the site can click and it automatically downloads a zip file containing music. (it's a site for a band who want their fans to be able to download their music.)A lot of the information I am finding pertains to PHP, which I don't understand. As I use action script 2.0, I am not familiar with much code.[code]but I most be doing something wrong b/c an error always comes up when I check the code.Also, I make a button, give it an instance name, but I don't enter that anywhere in the action script.so I know something has to be wrong, b/c the only thing I do is create a zip file, name it and enter it in the action script.
View 0 RepliesI want to implement a force-directed layout in my Flash program. On my search for an already-made component I bumped into these:SpringGraph (Flex component)Flare (Flare has a force directed layout class, but also a Flex component)GraphGear (AS2 implementation of force directed layout)Graph.as (AS3 implementation, but not so smooth)All these classes are not directly implementable in Flash. I tried to get the latest Flare running in Flash by using the Flex SDK files as well as for Springgraph, but this seems like a too complex way to create a force directed layout. The GraphGear is quite nice and compact, but written in AS2. Graph.as is too experimental to directly implement.
View 1 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.
