ActionScript 2.0 :: Detecting If A MovieClip Is Already Cached?
Feb 21, 2007
I guess my question is pretty simple for some of the guru's here, but i gave up with this already Im writing an photo gallery application for a website, everything works just perfect, but i have the following problem: Im using the events onLoadComplete and onLoadStart to display an small popup alerting the user while the picture is downloading... so how could i check if the picture is already cached ?, so i could use an IF statment to only show the popup if the picture has not been downloaded before? This is the relevant part of the code that im using right now, it works perfect, but it shows the "loading clip" EVEN if the picture is already there

I have a problem where I can't detect the end of a movieclip in my project.
I have the FLV video linked for actionscript, so that I can control it dynamically with a few other things using AS3.

I'm trying to load different images from xml to movieclips by detecting the movieclips name dynamically via xml.Pratically i have 2 movieclips named "sera" and "diurno".I take the names and the relative urls via xml then i try to add the images to the moviclip that have the same name as the xml, so i know that the "sera" movieclip have the "sera" image.

I'm trying to figure out when a child is added to a movieclip "x", and handling/detouring this operation from withing this "x" movieclip.
I tried overriding addChild and addChildAt at with no prevail. The movieclips that are placed on the stage via flash still don't trigger addChild or addChildAt. However, tracing this.numChildren shows '2' correctly.

I have a small tooltip which follows the mouse and asks the user to click in order to close a picture. The tooltip follows the mouse using:
startDrag("tooltip", true);
But I'd like to remove the tooltip once the user moves the mousepointer outside the picture.
Though, when you use onRollOver, the mousepointer changes into a finger. This is not what I'm looking for since the picture than functions and looks like a button. So is there any way to detect if a mousepointer is over a movieclip, without changing the cursor?

I'm working with a MovieClip ("mainMenuItem") that is linked to a Class ("GenericMenuItem.as") that uses attachMovie to add another movieclip ("Arrow") to mainMenuItem as follows:mcArrow = this.attachMovie(prefix+"Arrow", "_Arrow_symbol", this.getNextHighestDepth());I'm able to use on(release) within the Class definition to capture clicks on the mainMenuItem component, but haven't been able to find a way to detect a click on the "Arrow" library item that gets attached to that component.

If two movie clips instances of the same movieclip are placed on the stage and one is flipped horizontally in Flash.. Is there a way I can detect which one has been flipped horizontally in code? ScaleX seems to remain unchanged.The MovieClip has been flipped horizontally using the Flash UI (Edit->Flip Horizontal), not via code.

Is there a way to detect when any particular movieclip appears on the stage's timeline in AS2?
Attempt #1: The MovieClip.prototype.onEnterFrame hack
---------------------------------------------------------
All Movieclips have an Enterframe event. I set it to attempt to delete itself within the function so it runs once. Unforunately, this isn't possible (delete this.onEnterFrame) doesn't work, unless we delete the prototype.onEnterFrame dierctly as well. Of course, we can set the enterFrame to null, but enterframe will still be called despite it being nulled. So, what are the performance hits as a result of this?
Is there a way to flush away the MovieClip.prototype.onEnterFrame (by deleting it: deleting MovieClip.prototype.onEnterFrame), and then re-declaring it again "MovieClip.prototype.onEnterFrame=someFunc", so that layter clips that appear on-stage can be initialised accordingly with the enterframe "frame1" function? Yes, but redeclaring the function again would also apply the same enterframe event to the previous clips on the stage which had alraedy been initialised, which would waste more cpu cycles. Unforatunelay, it seems the Prototype thingy affects all instances on the stage, not the constructor itself upon initialisation. So, doing MovieClip.prototype.onEnterFrame=something, will cause all Movieclips on the stage to have that event, which is going to suck!!!
Could i hack the MovieClip cosntructor and create a totoally new one? But i think all these are hardcoded alraedy.
I want the function to run only upon instantiation of the MovieClip when it appears on the Stage's timeline.

bulletLoop: for (var i:int = bullets.length -1; i>=0; i--){
if (enemies[k].hitTestObject(bullets[i])){
trace("hit");

detect current frame number of a movie clip inside a loaded external swf?
its like this, i have a main swf, lets call it "loader_swf", inside the loader_swf i create a movie clip called "holder_mc" which loads an external swf, lets call it "ex_swf". The ex_swf has a movie clip in frame 2 which is the main animation of ex_swf. Is it possible to get the current frame number of the movie clip holding the animation on frame 2? the only thing i know is to get the current frame of main timeline of ex_swf.

There is the following bug in the gallery:Once you open up the gallery you see a container with all small thumbnails.If you start mouse over the main container you can see the following happen:
- shadow filter change
- quality of the thumbs change
There is a rotationY and rotationX on the main container. As soon as i remove that there is no bug and the shadow and quality of images is perfect.So what does flash do to children and their filters inside a container when using transform propertys before a MouseEvent happen to that maincontainer.You should use F5 a few times before you excaly can see it.

How do you know if the browser is actually using the cached swf RSL/library for Flex projects? I would like to be able to do different things from the preloader based on whether or not the user has never downloaded the library vs. they have it already cached by their browser.

My question is about XML loading. I need to avoid xml caching. On a web server, the technique is adding a random param to reload each time the XML file. But on local testing (in Flash CS4 IDE, CTRL + Enter), the following lines are not possible :
var my_date : Date; path = "toto.xml?time="+my_date.getSeconds()+my_date.getMilliseconds();
Is there any trick to bypass this issue ? I've read on different forum about the "delete" method, we delete the xml object and then recreate one new.

I'm coding an audio player using swfsound for non html5 compliant browsers. I've three sample files, sound1, sound2 and sound3.
After doing some tests, I've changed sound1, with other file, but surprisingly the original remains cached in the browser. I've deleted the original file, moved to other folder, no way.
The only way to reproduce successfully the new file is to active the "disable cache" feature. I'm looking for a way or method to unload the previous file (if there's one) before loading a new one. The audio player will be playing different mp3 files, and in the way that is working now, it won't succeed.

When we reference a SWF file from our ASP.NET page we append the version number to the SWF url, like App.swf?1.1.0.0. In a recent update, Firefox has continued to use a cached swf even when the version number changed, App.swf?1.2.0.0. We haven't noticed this behavior in other browsers.
Has anyone else seen this behavior? We don't want to disable caching completely. At this point we're probably going to change the name of the swf for each version, like App.1.2.0.0.swf, which seems a bit excessive.

My problem is that once flash reads an XML, it then wont read the XML again but rather uses a cached copy. This causes problems as I want it to update a record number in the XML.
My flow of data is like this:
1)Flash reads (and presumably caches) an xml file.
2)User enters data into flash (including update data for xml).
3)Flash sends data to PHP.
4)PHP edits XML file (adds a line and updates a record #).
5)Repeat above.
In practice what happens:
I have a recorded number recorded in the XML. (say 10)
Flash reads the recorded number from the XML. (still 10)
Flash updates the recorded number (now 11)
Flash sends the number to PHP which updates the XML (so XML is now 11)
When process is repeated: Flash uses cached XML so reads record number as 10!!

I need to load a range of images and make them crossfade over time in a never ending loop (rotating gallery).
Using the Loader I display a preloader everytime I load an image.
The problem is that the next time I load the image the damn preloader shows up in a split second (because I'm using the Loader to load the image again).
How do I write the routine of loading an image and reuse it again WITHOUT calling the loader a second time?
I read online to read a the bitmapData into a variable. Well, that's all fine. But HOW do I reuse that Bitmap in a never ending carrousel?

I have tried various codes (probably wrongly) and read different posts and failed to achieve what I am after. So to cut going round in circles I have just made a simple test folder. There are 3 things I am trying to achieve so that latest files are loaded instead of browser cached versions.
Everything is linked properly in the TEST folder (apart from the code to get latest non cached version)
You can download the TEST.zip folder (73KB) here- [URL] It's completely safe to download and please ignore the annoying pop up ads. I signed up for free service hence the ads.
The three things I want to achieve-
In the TEST.zip folder start with index.html.
1- There you will see >Enter Button< and >portfolio.pdf< button. Nothing will change on index.html page but the portfolio pdf will be regularly updated. So I want the >portfolio.pdf< to fetch the latest pdf always. I assume the code will go on the >portfolir.pdf< button?
2- >Enter Button< will take us to master.html page which contains master.swf. Master.html is only a container but master.swf will be regularly updated and needs to always load the latest master.swf version.
3- Load image.swf button will load image.swf. I want the button to load the latest image.swf file always.

using shared libraries at the moment for a scalable e-learning course. All the elements are to be used over multiple screens. BUT if I have to add a new element to that published shared swf - then next time I access my learning program it will have to download the WHOLE NEW shared library - is that right? ie: defeating the purpose in the first place. So if that is true then the best idea would be to use separate shared libraries. ie: sharedLibraryMusic1.swf sharedLibraryMusic2.swf for newer mp3s etc...
Or is this nonsense. ie: A new updated shared library with a "little" new element would not cause the whole swf to be downloaded again??? This is so important as it can make or break the download speeds.

We have a Flex application which doesn't currently use the Flex framework as an RSL. We're considering switching, but we're not sure what proportion of users will already have the framework cached.There's an added complication in that we're using the data visualisation components too, and we may have a choice as to which version of the framework we use.

In my application, I make numerous calls to preload images to brower cache in the background using Loader instances and ignore the complete event. I don't store the results in the application, but rather want to store them in the browser cache. The images have long Expires header dates.
When I want to use a particular image(s), I again use a Loader instance and call the same url and listen for the complete event to load the file to an Image.
The problem is that when I re-request the url for the "cached" image, it is making an http request with response 200 status, which I presume means it is hitting the server. How do I make sure that a request for a cached image never hits the server from Flex? I am finding that any request to a url for a cached image (with a long expires header) is making another request to the server, or at least that is my interpretation of it in Firebug.

We have a flash app (AS3) that reads some data from a local XML file and displays it in a cool way. The problem is that the browser(s) seem to cache this XML data, i.e. when we revisit the page containing the flash, it is rendered using out of date data (the XML file is updated regularly). We find we must visit the URL of the actual XML file and hit refresh (CTRL+F5) to get the new XML to load, and then go back to the page with the flash to see it rendered with the up-to-date data. Is there a way to remedy this? Perhaps the solution is like the one used to prevent caching of Javascript, i.e. appending a random GET param to the URL?

1. How long is an XML.load response typically cached for in Firefox/IE?
2. How long is an swf typically cached for in Firefox/IE?
I'm asking because I have an XML file that changes every few hours, and an swf that changes every few weeks. I'm noticing that the changes don't get picked up in Firefox, even after restarting my browser.

I am working on a page the allows the user, once logged in,to upload information and a picture. The picture is saved as his/her username, and if they upload a different picture, the old one is still displayed unless they leave the site and come back 10+ minutes later.I tried the HTML no-cahce headers and they don't even help load a new (up-to-date) version of the main movie.This should have an easy solution, that Adobe should have
addressed if they expect flash to be capable of being a dynamic site with user interactivity.

I'm loading an SWF animation and want to display it in multiple places concurrently, but the only way I could figure out how to do that is to load it every time I display it, as seen here:
private function playSounds():void {
for (var i:Number = 0; i < 14; i++)
{

What's the easiest way to prevent what I call preloader flicker. What I mean is the preloader works fine on first load but then once the external swfs have been cached the preloader still displays for just for a split second but doesn't have time to animate and it just looks a bit ugly. I ideally just want the preloader to appear on first load or force it to animate.
