Preloader And Speed
Hello,
i created a preloader of an external movie and it is working fine:
loadMovieNum("File.swf", 1);
this.onEnterFrame = function() {
_root.loadPercent=Math.floor(_level1.getBytesLoade d()/_level1.getBytesTotal()*100);
_root.loadBytes = Math.round(((_level1.getBytesLoaded()/1024)*1000)/1000)+"Kb";
_root.Bar._xscale = _root.loadPercent;
if (_root.loadPercent == 100) {
delete this.onEnterFrame;
}
};
Now i want to transform this preloader in a 8 type preloader.
So instead of having the line _rootBar._xscale = _root.loadPercent
i would have 8 "IF" conditions. So in each "IF" there will be a command, like changing _xscale of a MC, or fading in or moving it...This way i have a preloader which creates 8 diferent animations for 8 different loading .swf.
So My question is: by putting this "IF" inside my code, and since this code is in one "Enter.Frame" will i have problems with slowing down? I am afraid the time spent on testing which of the 8 actions to make will be enough for bigger parts of the file being loaded...so the loaded part will change.
Do u understand what i mean? So what do u think?
If this is not a good idea, could someone indicate me other options?
Thanks,
Miguel
Preloader With Speed Of Download
i came across this page.
http://www.eagames.com/official/thes...ding/index.jsp
the preloader shows the speed of the download (in kbps)
just curious how it was done.
anyone?
Connection Speed And Time In Preloader ?
how can i add current download speed and time remaining ( and time needed for download ) in my preloader???
I have found something about that on the board when i was looking for something else, and now when i need that i canīt find it.
Anybody knows the script for this??? I just finished my preloder with total and loaded bytes, loader status bar and percent....
but then i saw preloader with time and connectin speed and i want that on my web page
thanks!

Detecting Connection Speed For Use In Preloader
I had an "A-Ha!" moment, and I don't think I've ever seen it on this board, so I thought I would share.
It is possible to detect (estimate) connection speeds during the preloader. This would be useful when deciding how much of the movie to load before proceeding. For example, if you know that your user is on a cable modem, you know that the download could keep ahead of the playhead if 50% of the movie is loaded in the preloader. However, a 56k modem might require 80% of the movie to be preloaded.
In your preloader, prior to the loop, initialize a variable, and set it to the number of bytes loaded. Create a constant that stores a sample speed in seconds. Create a new function that reads the current bytesloaded, compares it to the old bytesloaded, and calculates the DL-speed based on the sample rate. Last, create an interval that calls the function every samplerate*1000 (since intervals go off of milliseconds).
Note: This must all be done BEFORE your preloader frame loop, so that multiple intervals aren't being created.
Here is how I coded it:code: var kSampleRate = 0.5; // This is the Sample Rate in Seconds.
var kDownloadSpeed; // This will be where the DL Speed gets stored
var iLastBytesLoaded; // a Public variable to store the initial bytes in
function GetDLSpeed(){
clearInterval(tDownloadSpeed); // Create your interval for sampling
// DL speed = (finalBytes - initialBytes) / time
kDownloadSpeed = (this.getBytesLoaded()-iLastBytesLoaded)/kSampleRate;
}
function SampleDLSpeed(){
iLastBytesLoaded = this.getBytesLoaded(); // Set your initial sample
// Create your interval to check ever specified time (Determined by sample rate)
var tDownloadSpeed = setInterval(GetDLSpeed, kSampleRate*1000);
}
SampleDLSpeed();Keep in mind that this is an estimate. Connection speeds vary, and will be affected by what else the user has downloading, but this is a good thing since we want to know the stream speed that this SWF is getting, not if they have DSL.
Also, this is not exact because intervals are not precise. A 1.0s interval may fire at 1.05s (See Flash's ActionScript Dictionary on setInterval for more info.) Using a larger sample rate will be more precise but take more time to sample.
Preloader That Detects Speed Of Connection
Hi,
I'm no expert in Actionscript so I'm not sure whether this can be done or not but what I'm looking to do is create a preloader that looks at what the users connection speed is (without sending a file to their computer i.e. like speed tests) and the has several outcomes:
Low Speed = image
Medium Speed = low quality video
High Speed = high quality video
Any help would be appreciated.
Speed Variations From 56k To Broadband Even After The Preloader?
Hello all.
I have designed a site whereby the frame rate is 50fps. When viewed on broadband this looks as intended. However I managed to view this on a 56k modem, and the expected result was quite different. Infact the loading side of things was ok, i.e preloader, but the main template loading was much slower even after preload. why?
Secondally the top part shape tweened very slow and the remaining parts were a lot faster, more like the orignal state.
Am I doing something wrong here, I must admit I have jumped in very quickly, but I was with the knowledge that we could avoid little hurdles like this, in terms of different browser types, connection speeds and what not.
I hope someone can provide me with a clear understanding why this is happening, and equally the solution that can prevent this.
There must be a work around. Once something is preloaded it should perform as expected right?
And if you are thinking its the computer, no! the other computer is just as good, however with less RAM.
Please I really would like some understanding in this area.
Testing Preloader On High Speed Connection
What could take 10 seconds to load on a 56K connection loads instantly on my high speed connection. Because it loads so fast, I can't tell if the preloader is working or not.
Is there any way to test it?
Thanks
Preloader Doesn't Work At High Speed Kb/s
I have a very weird problem:
I have created a preloader to load my swf with my soundfiles.
When I test it (double Ctrl-Enter) it works fine when the speed is 56K. But the minute I try something faster, like DSL, the preloader skips to frame 3 while the swf with the soundfiles load in the background.
Any ideas would be highle appreciated!
the script:
code:
onClipEvent (load) {
loadMovie("eksternLyd.swf",_root.lydMC);
//_root.lydMC.loadMovie("eksternLyd.swf");
_root.loadedLyd=1;
}
onClipEvent (enterFrame) {
if (_root.loadedLyd==1) {
total = _root.lydMC.getBytesTotal();
loaded = _root.lydMC.getBytesLoaded();
if (total>999999999 && loaded == total) {
_root.gotoAndPlay(3);
} else {
percent = loaded/total*264;
displayPercent = math.round(percent)+"%";
progressBar1.bar1._width = percent;
}
}
}
(the 999999999 is just to test...)

Streaming Audio Speed No Good - Depends On Processor Or Internet Connection Speed?
we are launching a narrated, streaming flash 6.0 presentation for a client. frame rate is 20fps. here is the link:
http://www.optionaldesigngroup.com/preston
they sent us this email:
"I do not know who else this may be happening with, but when Marjorie Sanders (OC) opened to take the tour, it loaded the software (not sure why her machine didn't have it), and the video was the size of a postcard, Kathleen sounded like a little child (almost munchkin like) and was going 100 mph (so very, very fast - almost unintelligible). Can we experiment with it. Could it be because of the download - I would hope that people don't receive it that way or they will end up laughing at it (it is almost silly)."
does the streaming sync depend on the internet connection or the processor speed? i am assuming processor, and that on a kick-butt new machine it will stream faster then on a slower one.
i think the only way to counter for this is to go in and add some more frames in the narration between phrases. we don't want to lower the framerate because it will affect the flow of the tweens.
any thoughts on this would be greatly appreciated. thanks.
Problems With Speed: Loading An Animation Dynamically...reduced Speed Why? W/exampl
Im loading an animating logo dynamically into a site. The animation works in normal speed if i access it directly:

[MX04] MC Speed Vs. Document Speed
I'm an intermediate to flash, and know limited coding.
But,
I have created a flash slideshow with a preloader. However, the preloader needs to be at 12fps in order to look good, but the slideshow is at 0.4fps to look good. (It basically just flips to each image.) The controller is a sample controller in flash, and I wasn't sure how to activate the delay switch in it, so I just set the fps of the whole scene at 0.4fps.
Anyways, is there a way to have the whole slide show at 0.4fps but the preloader MC at 12fps, or sped up or something. Thanks!

CPU Speed
I am designing a Flash site on a Pentium III 500Mhz and when I tested it on a PIII 1.1Ghz, the sounds lost all synchronization with the animations since the animations are much more faster than the sound. When I lowered the frame rate, everything worked fine.
Is there a way through code on how Flash detects the CPU speed and automatically arranges the Frame Rate? Or is there something else I can do so that when exporting my code to a faster CPU, there is no change to my original site?
Thanks

I have a 109k swf file, and I have created a preloader and works great in my computer but whenever I check it in another computer graphics play slower and sound just goes on at its normal rate. I know that depending on the power of the computer is how fast is going to play but I think has to be a script that will read the computer capabilities or system speed and then it will play at an assigned frame rate according to the system capabilities. Is this possible or not? or do I have to create 2 versions where one of the movies frame rate is faster than the other so the user can pick one according to their capabilities. Please help or send me a refference where I can go end check this inconvenient that is making me crazy.
Note: All this is being tested on T3 conection.

Speed It Up
If u check out
cirquelemasque
you will see the way the interface moves left or right. I know if i change the base rate it will make it move faster or slower but what cna i do to make it work faster on slower modems. the overall file wiht intro is 570k. the intro is 200k and 370 for movie. I f i seperate them and make an intro for both, wil lit make the movement faster for slower computers.
Also I will accept comments about the site, Its in its final stages and is live, but I am tweaking it

I've got a general curiousity question: why exactly does Flash run so damn slow?
I've got all sorts of programs on my computer that do things countless times more complex that what my game does, and yet they run at a much greater framerate. How is it that a 2D program chugs along so slowly? Was it a concious decision by someone to limit the amount of processing power Flash gets, or is it just really inefficient?

Speed, Speed, And More Speed - HELP
Hey guys and gals, this is a weird issue I have, I'll try to explain it the best I know how.
Here we go..., I am creating a CD portfolio in Flash and everything is going great. yeah! But I have come across a problem.
I have a main interface which is a swf published as a html file. The user can click on several buttons, these buttons load pictures, videos, and interactive stuff. These files being loaded, are in a seperate folder. I am usin the getURL to well,...get them.
The problem is...It takes forever to load the videos!! Correct me if I'm wrong, but its on a CD, it shouldn't take 2mins to load a video, it should be instantaneous. Its fast when I test it on my hardrive, but not when I test it on my CD!
I need any expert advice you gals and guys may have. please help.
Speed Changes
hi. i've got a shell movie which loads 5 external movies with five buttons.
the first time i press any of these buttons, the movies load and their speed is fine (they're all set at 40fps).
but the second i click a button a 2nd time the speed increases. i'm pretty sure the frame rate cannot increase but i just don't see what i'm not clearing away when i load another movie into my single placeholder.
i was hoping someone might be able to point me in the right direction. i've attached the files.
thanks in advance. fumeng.

I am viewing a web page from 2 different computers - both have Flash Player 7 installed in IE. Actually Flash Player seems to work better in Firefox than IE, but then again what doesn't?
When I view this file on the 2000 machine (the other one is xp), it plays much too slow, even after the whole file has been downloaded. Is this processor speed? Doesn't make sense as both processors are fast.

Also, what processors do you all have? What ones help flash run at peak performance?
Need More Speed
Can anyone please show me how to speed up this scrolling mc:
i have a long mc which will be full of thumbnails, and it has left and right scroll buttons which move the whole mc left or right. The movie has a frame rate of 60.
The mc and the buttons are all in an mc with these actions on it:
Code:
onClipEvent (enterFrame) {
if (frameCounter%speedFactor == 0) {
if (sliding == "left" && picBar._x>-588) {
picBar._x--;
} else if (sliding == "right" && picBar._x<-382) {
picBar._x++;
}
frameCounter = 0;
}
frameCounter++;
}
Inside that mc there are these actions on the timeline:
Code:
scrolling = 0;
frameCounter = 1;
speedFactor = 1;
The buttons have this code (this is just the left one which is obviously almost identical to the right):
Code:
on (press) {
sliding = "left";
frameCounter = speedFactor;
}
on (release, releaseOutside) {
sliding = 0;
}
Please tell me how to adjust the speed of the scroller, everything i've tried either makes no difference or slows it down.
Speed Changes In Web
I searched the forums for this question, but didn't find any that helped to answer it.
The scenario:
When I make files, they run perfectly fine in 30 fps, in the preview mode.
They work perfectly fine as a .swf running off my pc.
When I upload it to the web, the frame rate drops considerably.
I have tested it on the Safari browser as well, so I know it isn't just my own PC.
Here are the two files, you can see for yourself:
Web version: http://members.cox.net/projecthappy/BDcard.html
.FLA version: http://members.cox.net/projecthappy/BDcard.fla
The point was for the cake to fall right during the 'woop' sound, but its off-sync in the browser version.
I'm having this same problem with any other file I try to put online. Even very basic and small files.
Your help is greatly appreciated!

Speed In As2 And As3
i wasn't sure where to put this as it concerns AS2 and AS3.
The first language i ever learnt was AS2 and i am very proficient in it now. However, i'm working on a game and speed is very important to me.
Do you think it's worth learning AS3 for the speed difference? how difficult is AS3 to learn? and how much faster is it?
is it sufficient to use AS2 on flash player 9?

[Q] How Would You Speed This Up?
Howdy...
I was about to sleep for tomorrow and I had some thought... So, I have this one... It looks okay, but I think this one is not 'fast' enough as a transition...
Basically I have one image on the stage and have a mask that is composed of multilpe boxes and I am just removing individual movieClips to do this...
Here is the test result...
Code:
// 1 // 5 // 10
1 Interval : // 5551 // 3753 // 3511
2 Interval : // 4392 // 3484 // 3343
3 Interval : // 4040 // 3395 // 3222
4 Interval : // 3889 // 3327 // 3208
5 Interval : // 3716 // 3286 // 3227
6 Interval : // 3652 // 3197 // 3120
7 Interval : // 3634 // 3181 // 3088
8 Interval : // 3563 // 3172 // 3088
9 Interval : // 3546 // 3692 // 3066
What that table means is that if I run five intervals(row) that removes ten grids each time(column), it takes 3227 ms...
