ActionScript 1/2 :: Reusing / Storing Loaded Content In A Movie - Cache In Flash
Jul 8, 2010
Suppose you have a slideshow movie that loads content such as images or Flash movies itself and continually replaces content with new images or movies as a viewer browses through content. Is there a way to store images or movies that have been loaded so that if the same content is selected they do not have to downloaded again? Presumably once content has been unloaded or something has ben loaded into the same level the data is wiped from memory and has to be downloaded if it is displayed again. How could content be stored in Flash or does the content stored in the browser cache take care of this?
I need to load an external resource and be able to reuse it (create new objects based on that resource). I need to create multiple objects using that resource and I don't want to load it again over and over every time I need to use it. My question is: How can I load a resource (in my case, it's a collada file ".dae") once and be able to reuse it again?
I used Gaia framework to build a self-scrolling slideshow. There are only 4 pages in all, but I have realized to my dismay that each of these pages are requested over and over from the server. If you leave the page open and the animation goes by itself, that can clobber our server.
What can I do to prevent this? I wonder if there is a way of writing a URLRequest so the pragma header can tell the browser to use the swf from its cache rather than requesting it again?
Note that I am not using SWFaddress so the requests are going to the same URI.
i working on a project that load images localizend on a server. For optimize the RAM usage i remove the images when they aren't shown, and re-load them when is necessary.
But are this images saved into the PC cache so that the second, third, forth... time that i call it, they will be loaded instantly? Or flash need to download it every time from server?
I have a media player, which rotates images for the artist it plays. I load the images dynamically into the flash. The flash downloads the same images from the server over and over, how can i cache the images, so flash grabs them from a local cache and not from the server?
I've uploaded my slideshow swf to my WIP website (CSS files got overwritten ) Everything is working great. It's looping, I have a preloader animation, ect. The problem I now want to resolve is getting the loader to cache the image files. When the slideshow is told to go back to image[0], it reloads it again. As the whole point of this project was to work around my free web hosting's bandwidth limits, as well as getting more experience working with XML, this simply wont do. Imagine if someone browsing my site left the main page running for a few hours! What I need it to do is to somehow force the browser to cache the images once they are loaded, or at least I think this is what I need to do? Here's the code again:
I'm doing a filmstrip animation and each frame of the strip has a small pic on it and using TweenLite, I'm making it expand and contract on mouse rollover and rollout. That's not the problem. Since it's basically the same function, I don't want to have to write it for all 16 frames. I thought I'd try 'this' but that doesn't work on AS3. So I'm trying to find a solution that does. Here's my code (for one frame of the movie....in this case, the eighth).:
I've got an application which loads anexternal swf, then needs to add content to a specific depth in it. It does this by finding a named placeholder clip and replacing it with a UIComponent, using addChildAt(); This seems to work fine - I have a trace utility that walks back up the display list and it shows my UIComponent right where I expect it, then the parent movie clip, then all the containers up to the stage. At each level the container is a) visible b) 1.0 alpha and c) the size I expect it to be, and from my trace I can see that I have a structure which looks something like this:[code]
All well and good, but if I draw a rectangle on the graphics of the UIComponent (or add an image to it, or do anything else), nothing is visible. I can trace any parameters of the UIComponent, I can use it to make changes to its parent SWF, I can even note that if I draw a rectangle on the UIComponent which is larger than the Loaded SWF, then the SWF changes size to accommodate the new bounds - but I can't see a thing.I was wondering if some security stopped the parent application adding content to the Loaded SWF, or if there was some other issue.
If I use an empty movie clip to load a series of images into,how do I get them to load in the center?The images are all different sizes.I think this is fine, if they loaded with the center of both the target clip and the image aligning.Upper left registration point for the target is not good.
I am using a timer in my flash movie. When I close the flash movie, I want to store the last currentCount value. Is there any predefined option available in as3.0. ?
I have a web based slide show that reads an xml file and loads images from a folder on the server. The client would now like to also offer this slideshow on a cd. I'm pretty sure that I can save all the assets to on the cd and the slideshow will work. But the client is concerned that someone with the cd will be able to directly access the images on the cd. So, here's my non-flash flash question, can the folder storing the images on the cd be hidden yet still be read by the flash movie?
I'm currently working on a project that needs to request a url multiple times. Having studied the the HTTP Proxy (Charles) it seems that AIR will cache the first response and then return the same response for each subsequent request.Does anybody know how to know if the response has been cached other than setting the URLRequest to useCache, but this doesn't say if the response was a cached response or not. The digest isn't set on the URLRequest either, although it does mention this is for swz only, so how does it know if the content is the current content or not? Is the responseHeaders used to find out how long to hold the cache i.e.Cache-Control: max-age=900
Also does anyone know how to flush/purge the cache or are we at the whim of the GC and in that case how does it know if to leave it in the cache or now?This makes sense to me, but still I would like to know how to regulate this cache.Further more: I've tested a set up where parallel URLLoaders (10) are made and created which open the same url to see what happens in that instance. It seems that each parallel request is made until a successful response is given, all subsequent calls are then cached. Calls which are sent out before the successful request is then completed. It looks like the items which are already in being processed do not use the cache and return with correct data.Additional The AIR runtime doesn't even send a "If-Modified-Since" header, so the cache isn't even honoring HTTP protocol. So it seems as if Adobe has implemented it's own version of a cache which doesn't even use HTTP/1.1 Header Field Definitions.
We have a web app. built in flash that allows customers to upload images and text, customize the container in which these will be shown (a swf file) and then embed the code into thier website. There is also a sharing options that allows their users to display this container, together with the content, on their websites. (For e.g you can see the container as the Youtube player and the content as the videos the user chooses to show). The swf container uses an XML file to know what to display.
Now, I am not a flash developer, but a person who takes care of the project.We are currently working on the app and the swf and we still find bugs. Every time we fix sth, I am told to erase my cache to see the changes. My concern is that the client/users might not see the newer version that we make available, but the old one. We can't tell them to erase the cache and we can't afford to renounce using the cache since the images are big.I was told that, sometimes, the browser does not see that the current version is a new one and loads it from the cache (actually, it never detected that there is a newer version and I always had to erase the cache). How can we tell the browser "now, load the swf from cache" or "now, don't load the swf from cache".
Trying to work out how I can tell if a downloaded file came from the cache or was freshly downloaded over the net. I need this because users will download multiple files and I am trying to give make an accurate downloader for them. I have made them download a sample file which I have made not to cache by doing the following:
private var _loader:URLLoader; private var _rootPath:String; = "http:/example.com/speedTest/f4v/"; private var _startDownloadTime:int;
If I load an swf into a movie clip, and then load another swf into that same movie clip. Is the first swf stored somewhere or is it totally gone when the second swf is loaded? What I want to know is if I need to have as many movie clip holders as I have swf's. Else they would have to load every time they were called.
How to remove a loader and its content using removeChild or any other way, I had removed the loader but its content still playing in the background i know that from the sound of the content.this is the my code for removing:
The whole problem is in the title. I have a gallery which looks a lot like coverflow. Each button in it loads a new gallery which is a swf with a new XML. The Problem is it only works on the first time i click on a button. The XML does not renew when i click on another button. It does load the new XML.
I'm doing an Image Cache following this method: [URL] I copied the two as classes, renaming them CachedImage and CachedImageMap. The thing is that I don't want to store the image after being loaded a first time, but while the application is being loaded. For that, I've created a function that is called by the application pre-initialize event. This is how it looks:
I'm working on a chat application that retreives user profile icons from remote sources (e.g. Blogger, Yahoo, Gravatar, etc). Easy to get the images in a Loader and display them. The problem is that a single thread could have hundreds of records, but probably only 10-20 active commenters. In a standard browser, each <img...> link after the first one is cached, so you only hit the source site once. Is there any way to cache/store/copy those images within Flash to avoid requesting the same image over and over?
I can do it in the Local sandbox by accessing the BitmapData of the loader content and cloning a new bitmap for subsequent instances of the same request URL, but of course once the application moves to the Internet the security system requires a Policy file allowing bitmap access. I don't need to manipulate the bitmap at all, just copy it. Or reference it as content from multiple Sprites, or something along that line. Once I've downloaded the image once, I don't see why the security system would prevent me from displaying it unchanged as many times on the page as needed.
I am in the process of building a site for an Architect... Jamie Fobert Architects (projects) I am useing transitions between the projects and am loading details/text and images externally through flashvars, php and a mySQL database. Within my transitions I have a a preloader on the forst 2 frames the code is as follows (taken from a Voetsjoeba tutorial):
[Code]....
This works pretty well if the content is within the .swf, but when it is loaded externally it doesnt preload it at all. Does anyone know how I can adapt/improve this preloader? or somehow ensure that all the content being loaded externally is loaded before the transition plays?
I have a problem with my New Loader class I use as3 and buttons to load external files into into my main swf file and I resize the external files to match my stage but they always load from the top left at x=0 y=0 The action script i use is
var swfHolder = new Loader(); mybutton_btn.addEventListener(MouseEvent.MOUSE_DOW N, mousedownpresser); function mousedownpresser(event:MouseEvent):void { addChild(swfHolder) swfHolder.load(new URLRequest("myvideo.swf"));
Is there any way I can load the external files into a different position?
I have a flex Air program that loads external content with the HTMLLoader.Now for some reason whenever I load a page that has any flash content a blank system window pops up outside of my program. It's completely blank, all white with min, max and close buttons.If I close it any flash content I loaded stops working. For the life of my I can't figure out what's happening and there's no messages in the console and no title for the window.
private var webPage:HTMLLoader; private function registerEvents():void {
For example, If I have a SWF that loads XML and images, and displays them, is there some kind of 3rd-party tool that will take this SWF and re-render it as if all the text and images were embedded and not external? So I could just use the same SWF without it relying on image and xml data files?
I want to store their locations as a variable, then just call that variable in a Tween. I read somewhere that it has to be an Array. However, I don't know how to call it without getting commas in between instead of dots.
ActionScript Code: var boxContents:Array; boxContents = new Array("content_mc","home_mc","homebox_mc","homeText_mc"); removeContent = new Tween(boxContents,"alpha",Regular.easeIn,1,0,1,true);
