Flash - LoadVars Doesn't Wait Until Data Is Loaded
Jun 8, 2009
variable = 0;
function change() {
variable = 1;
}
[code]....
The problem is that it executes #Second before #First, which means that the object is not fullly loaded but the code continues nonetheless. Is there a way handle this? I have tried using a while loop, but this is ugly and makes flash crash. Is there any decent way to handle this, does it have to do with better code structure/program flow or is there a technical way to make it wait? Also note: This code is executed on the server side, which means there are no frames involved.
UPDATE:When projects get bigger, this gets very ugly, especially when you are retrieving mulitple things from a server, you have to use very deep nesting, you have to keep repeating the same code, example for buying a serial:
I have two classes: Level, which dictates a tile-based level, and MapLoader, which loads a text file on my local machine.I am calling a load function through Level asking MapLoader to load, but when I try to parse the data, MapLoader isn't done with the load.I've tried putting the load in a while loop, but it just freezes. Here's the MapLoader and the function in Level.[code]
I have a slideshow that loads image files with the BulkLoader class from here. When the first image is loaded completely, it gets added to a MovieClip container to add it to the stage.. and it gets displayed fullscreen, but only if a button is clicked:
fullScreenButton.addEventListener(MouseEvent.CLICK, showFull); function showFull(e:MouseEvent):void { stage.addChild(mcSlideHolder);
[Code]....
This works fine unless the fullScreenButton is clicked before the image is loaded completely, then of course nothing is visible. How do I get button click event that calls showFull() to wait until the image is loaded/added to the container or how can I add it again? What is a possible/the best approach?
I tried dispatching a custom event "firstImgAdd" that adds the image again to the container when the fullScreenButton is clicked, as well as with a try/catch block or even a simple if condition but none of them worked, meaning the image does not get added to the container after it has finished loading when the button is clicked too early.
I am still working to fix a FIRED developers code he left us with. The code in question goes out and request information from a database, places it into arrays and also checks session. THis is what I think it should be doing. I am getting a bunch of undefined returns ( prints out in the assigned text fields). Is there a way to make Flash WAIT until all the data has been retrieved from the database. This is out first theory.
For the life of me, I've tried everything: I've researched LoadVars on Adobe forum, used David Powers' books, googled 'flash to php', LoadVars, etc. and tried sendAndLoad, send, and using $_POST, $_GET, $_REQUEST. $HTTP_POSTVARS but I keep getting this same error.
I have a Unix server running Apache/PHP 4 - LoadVars worked to load name-value pairs into an array -see thread)
My goal with this simple app is to prototype being able to pass a variable from flash to a variable in php.
Parse error: syntax error, unexpected T_VARIABLE in flash_to_SQL.php on line 5
Actionscript 2.0 code:
var c :LoadVars = new LoadVars(); c.testing = "123FOUR"; c.send ("
This code is being run from a frameset in IE8. When the new window is opened, the form data is not being recognized. It appears that the http header, "content-type: application/x-www-form-urlencoded", is not being passed into IE and this is causing the post data not to be processed. The data is there, IE is just doing nothing with it.
This code works fine in FF and Chrome, and in fact the correct headers are passed in FF and Chrome.
NOTE: The new page is on a different site, but i don't know why that would cause a problem with a POST and not a GET.
I have tried adding the header to the send request, but that has no effect at all. The contenttype header is still missing and it still works everywhere but IE.
My current work around is to use a GET instead of a post, but that's ugly and it limits us in the size of data we can pass but for now at least it works.
I would like to send data from PHP to Flash however, it sends just fine but when displaying on Flash, it does not display the contents in the variable. Instead, it displays the name of the variable. This may be a simple answer but I'm quite new to this. Here is the code in Flash.
I have a new dilemma concerning external preloaders.Now I found out that sometimes external preloaders don't wait to load the entire swf file before this last one runs.I understood the concept and I applied both explained methods, but still couldn't find a solution: the swf file runs before the preloader finishes to load.This is my code (useless) so far:
import flash.display.MovieClip; var myLoadedMovieClip:MovieClip; var contentLoader:Loader;
in the tutorial with the code LoadVars(); like this one and this one, shouldn't it be important to have the capital L on LoadVars(); ?loadVars(); doesn't work.
we are making an app that uses a lot of images. Is it possible to preload all the images at the start of the app ? So the user doesn't have to wait in beteen switching the images.
I have a problem when I try to use the loadVars class in an ActionScript 2 (CS3) file. Actually, it works fine in the debugger but it doesn't work at all from a web browser (IE or FF).
This is my AS code :
ActionScript Code: _root.testURL = "http://REMOTE_SERVER_IP:PORT/FILE.html"; var myLoadVars:LoadVars = new LoadVars(); _root.info.text = "Loading...";
[Code]....
I can see "File loaded" in the info text field, but the file is not called (I checked the server log) when the swf file is loaded into an HTML page and displayed by a web browser. Thus, _root.sr.text is set to undefined.
I've got a simple text file which I want to read with LoadVars:
Code: &tekst=This is a test&
I'm loading it with LoadVars and let the text of one dynamic textfield be replaced by the 'tekst' variable.
ActionScript Code: stop(); var my_lv:LoadVars = new LoadVars(); my_lv.onLoad = function(success:Boolean) {
[code]....
This works offline, but online the text isn't replaced? This should work right? So what's wrong? All I've got is this one frame with code and a dynamic textfield.See attached files. The published files .html .txt and .swf are all in the same location.
Im working on a project that has a main swf file associated with the document class. It loads XML that provides the text content for the project, then it loads a swf that contains a font in its library, then it loads the first of several content module swfs. When the font swf has inited, I'm registering its library font with Font.registerFont(), and using it in a TextFormat object. After everything is done, I can add code to the document class to create a text field on the stage of the main swf and format it successfully with the TextFormat object, but when I try to do the same thing inside the loaded content module swf, the text doesn't show up there at all.
My program reads a rather large data file that is crucial to the display of the program I am making.I have an event listener that waits for my loader to load all data from the file, and it then adds all the data (and parses it) to a 2d array.Unfortunately the program flow doesnt wait for the loading to finish, so when it checks the array, it is still empty because nothing is loaded into the array yet.
I'm stopping on a keyframe, then using setInterval to advance after a specific timeout. The first time through everything works fine, but when the movie loops (user-initiated) and it gets to that keyframe with setInterval again, setInterval immediately advances the timeline and doesn't wait any time at all. The keyframe in question is coded like the following:
I am trying to load several swf files into various containers. In one scene I have used the following: createEmptyMovieClip("container1", 1);loadMovie("MC.swf", "container1");
And I want to wait for it to load complete before moving to the next scene and doing the following one... createEmptyMovieClip("container2", 2);loadMovie("MC2.swf", "container2");
I have two Flash banner ads, built in CS5.5, using AS2, that will be placed on a page together and appear to interact with each other when played at the same time. Similar to this: [URL]..
The problem is that they might not load at the same time. How can I get each banner to check that the other has finished loading before playing?
I had read that LocalConnection was the way to do this, but I haven't been able to find anything that explains it well.
essentially, I'm loading some clips dynamically via xml offstage...they then pan to the center of the screen. Pretty easy, except the files (about 100k+) aren't loading fast enough, and they're showing up halfway through the tweenYes, I know, I need to wait until the clip has loaded...but how? I've tried onLoad(success), getBytesLoaded() ==getBytesTotal() etc...but I can't so much as get the file size of the file at the end of the xml branch. Before I go any farther, here's the code:
I'm trying to load an external XML file into my program using onLoad callback function. The problem is that the script will continue to run without waiting for the file to load. Is there a way to do that?
In this app/website I'm building, I will be making many requests for data (via an external PHP file that queries a MySQL database). I'd like to build this request mechanism into its own class so I can reuse it.What's the best way to handle this? I'm thinking the following would work, but I'm a bit lost on the last step:1) From the main class, call a method in the query class (with whatever arguments apply, to specify what data I need etc).
2) Set up a listener in the main class and make the program enter a sort of "wait" state (possibly visually, if these requests wind up taking more than a half-second or so)3) From query class (upon receiving the data), dispatch event to let main class know it's received the data.4) Send data to main class. <---- How should this be achieved?For #4, should I create a custom event that dispatches with the data inside the event object for the main class to receive when it's notified? Will this be a problem if I have lots of different types of requests (will I need a new custom event for each type?)? Or is there some other sort of "return" I can/should use (similar to calling a function that returns a value)
All the examples in the text books, etc. show the LoadVars object being used with a .txt file. Can I use it with a .xml file or not? I have tried but the output panel just shows rubbish data!
I am using the loadVars class (Flash 8) to load key/value pairs from a mySQL database through php (example &pic1=pic1.jpg&pic2=pic2.jpg&...).
The ultimate goal is to create a dynamic slideshow with a variable length, depending on how many pics were submitted by the user. Since the associative array object returned by loadVars does not share the "length" property of indexed arrays, my guess is that the values need to be converted into a new indexed array before being able to use them in the slideshow.
I'm messing around with trying to load variables from a text file and it's just not working as I'd expect. First, my text file is formatted like this
[Code]...
For example, if I do something like create a simple Dynamic Text Box on the same frame as the above code, to show the value from _level0.Test.variable1, it displays "undefined" even though the debugger indicates this variable has the value "value1" as I wish it to. (using "trace(_level0.Test.variable1)" yields no better results)
I have attemped using onLoad and onData alongside the above code, and neither one has made the situation better. I have also attempted trying to reference the variable in a few different ways, and it's just returning the same thing every time. When I was experimenting last night, I managed to get the variables to show up properly on a "trace()" but not when referenced by other things in the flash file. Regrettably, I cannot remember how I did this. Either way it didn't quite work still. Do I need to do something else to be able to reference loaded data in my project, or is there some fundamental mistake I am making? I'm usng Flash CS3 Pro, if that makes any difference. Flash Player is up to date, etc.
I'm loading data from sql, by using asp.net. I've made the script in vb, but now i have problems with flash. I can load data, by using Code: trace(this.body); But i dont't know how to get the data with the while loop
I want to write out some names from a DB and then get it with loadvars and then put it in an array for easy using later, how do I do this the best way? First thing first I have made an ASP file like this: Code: <% Dim objConnect, objRS, SQL, strConn, i Set objConnect= Server.CreateObject("ADODB.Connection") Set objRS= Server.CreateObject("ADODB.Recordset") [Code] .... How do I loop out this thing and put it all in an array =?
I'm using Flash MX (2002) and I need to get my variable values saved to a server each time my test subjects run and finish my swf/fla (PHP scripts and a .txt file on the server are being worked on, but that's a different nightmare!). I'm pretty sure I should use LoadVars, NOT SharedObject for this data capture right?. The data must not be overwritten each time over the course of a few months of data collection. The 3 variables are: username (name of the user), counter (this keeps track of which version the user chooses from the start menu), numcorrect (keeps track of the number of times the <right> arrow key is pressed).
2 main problems: I don't know where to put in the LoadVars obj (in the AS code of "finaldisplay" frame?) AND I don't know how to build/format the LoadVars object to capture the data in the 3 variables I listed above. I've got several Flash books and have done online tutorials, so for something so simple (3 lousy variables!)...why is my life so miserable? Here's my zipped .fla.
My Flex application does a remote call to weborb to save some data from Flex. When this data is saved, a service is called on another server. All this time Flex is waiting for an answer. Is it possible to call this service (on the other server) and not wait for an answer. I have tried to call the service asynchronous but all this does is calling the service in a different thread. Flex still has to wait for both threads to be finished... So when the data is saved, flex should get its answer. (while the thread handling the service is still running).
I was trying to create a preloader that preloads content loaded by the LoadVars() Object. For some reason, the getBytesLoaded and getByetesTotal variables of the LoadVars object kept retuning a null value. Below's how I do it:
PHP Code:
var news_lv = new LoadVars(); var url = "news.aspx" news_lv.load(url);
