ActionScript 2.0 :: Maintaining Persistent Variable In MC
Nov 25, 2003
I using FlashMX to read in a value from an ASP page into a dynamic text box. This works fine.
I then use a motion tween animation to tween into another image, and there I put another instance of the dynamic text box, with the same name, but the value doesn't populate the text box. It's as if it reads the variable into the text box, but if I do anything to the text box, it loses the variable and can't get it back.
Further, if I switch back to the first frame, the value won't populate either, I have to refresh the browser page to repopulate the variable (read the ASP page again.)
Is there a way to maintain this variable throughout the movie, so that I can re-use it?

What packages and/or classes do I want to look into when I'm trying to make a Flash program that will run on multiple desktop and mobile platforms and I want to use persistent data?
Edit:I am working on a program that will allow people to study certain texts following a daily study program. The text is different every day, and I want every person to be studying the same thing. I intend to export this to Projectors for Mac/Windows and I would like to allow people to use it on mobile devices as well. Preferably, the program should not require internet connectivity.
I'm trying to create a persistent MP3 player using SharedObject. Initially I tried using frames and while it worked, frames suck so I continued looking into it.I came to find out about Flash's SharedObject. It seems easy enough but I can't nail down the logic correctly. I've attached a sample .fla for anyone interested to look at. I need the song progress to be stored and retrieved when necessary to keep the same song playing whenever links are clicked within the HTML page.
i'm overwriting the original SO each time i save to it here are my proto functions:
Code: interfaceClass.prototype.saveLSO=function(){ //saves color set vars to local shared object (cookie) on disk this.myN="gamecookie"; //name of cookie file trace("saveLSO");[code]....
i know i should do some kind of test, but the way to do it eludes me.
When we do XML.load on flash application, then we do netstat on the server-side it opens a persistent connection. Im finding out the reason why its doing that, it should be close right away when the xml loading has finished. problem is the connection remains open.

The idea behind is a multiplayer browser game which interacts with a PHP server. Right now it works like this: Every second the browser is doing an ajax call to the php script which checks everything and returns the response. All in all it runs fine, but the problem is that the browser gets overloaded (because of thousands of ajax requests) after a while and it becomes impossible to play anymore. Also the delay of 1+ second is pretty much. My idea is to have a simple flash pixel which will have a 2-way communication with the server. For example:
I have a question regarding the following tutorial and an older (inactive?) forum thread based around it:
Adding Thumbnails Tutorial XML and Flash Photo gallery with thumbnails in a grid (2006 - 2009)
I have multiple pages, several with thumbnail galleries, and several without. On the pages with the galleries, everything appears to render correctly. However, when I go from a gallery page to a page without a gallery, the thumbnails don't disappear. Instead, they remain on top of that page's content.
How do I get rid of the thumbnail gallery on non-gallery pages?

I need to develop a site with a navigation SWF file that changes the content of an HTML page, WITHOUT reloading itself and thus losing its current state. What I think I need to do to have smooth transitions, is keep the same swf file loaded, while having it change the page content below it.
I have some complex html content to include in the pages that is not supported by the tags available in Flash's dynamic text boxes. I have considered the idea of iframes, but I don't know how to load iframes using flash, or how to use them without refreshing the page.
i am currently working on a facebook game and i have a problem concerning the integration of a life counter which regenerates over time for a facebook game. The game is a simple Flash/AS3 shooter in which users are competing for the highest score. For monetary reasons every game costs one life and users should only be able to start a new game, if said life counter is >=1. To clear things up, i submitted a link to Popcap's facebook game "Zuma Blitz": ZUMA Blitz I can think of a few ways to do this, but i don't know which is the best/easiest approach. Would it be best to:

I can think of a few ways to do this, but i don't know which is the best/easiest approach.Would it be best to:Make it in AS3 with server communication via php?Or do it in JavaScript and communicate the count back to AS3?Another maybe related question is, how do i tell my database that the data from the life counter should be stored when the game is closed (for example by closing the browser).Can i do this from Flash or do i have to apply a html/JavaScript method?
Is it possible to define the scenes and the frames in XML in Flash CS4, so that we can parse it in actionscript 3.0 and define the interactivity. I want to define all the UI elements and the event associated with UI like List control or button in XML format (XUL??) and then use actionscript to build the application logic. Are there some good examples?
I am creating a site in flash, and I have always had this problem when I make flash sites. How can I eliminate a scroll bar in the browser, and make the swf fill the entire browser window no matter what? Is it something I need to write in Actionscript? the HTML page?
What I want to do is to fill in a movieClip with information I get from the MySql database and then maintain that MovieClip throughout the site which has swfs and web pages. how it is best done and easiest? Would a FlashVar have to be used? Could I just load something and have it stay inside while everyone accesse it?
I've got an algorithm that takes more than several seconds to complete. I'm trying to implement it into a 60fps flash game i'm creating. I am wondering if there is some provision in ActionScript3 to interrupt a computation in order to update the frame and continue the computation afterwards. There probably isn't, so I'm assuming the best method would be to perform the computation for x milliseconds, measure what the frame rate is after, then adjust the time the computation will run for next frame if the frame rate is less than or greater than 60 fps. The drawback with this is that the game won't run at a steady 60fps...
Any other ideas on how to (optimally) perform a large computation in AS3 while maintaining the framerate? EDIT: For the curious (the calculation, perhaps I should have said algorithm): I'm creating a motion planning library for game AI objects (one use for motion planning). The algorithm is along the lines of a RRT (rapidly exploring random tree) that iterates thousands of times. Demo link:[URL] Click to motion plan. The circle can "thrust" at a fixed magnitude in any direction. Also - there is no linear velocity damping (i.e. friction).
I am working on a paint application, I am able to draw lines, draw shapes, erase. I need to implement undo and redo functionality. I plan to store history in a bitmap and put it in an arrayMy question is whether we can have an alternate solution other using bitmap class. How can I store coordinates of non straight line without using up lot of memory and processor.
I have a project which, for all intents and purposes, attempts to create an online text editor/word processor. The key thing is that I need all multi line formatting to be retained and sent to the server. ie, if the user enters a bunch of text (all colors/bold/fonts and stuff are working great) which has a carriage return or a line wrap, I need a way of tracking that and inserting some kind of flag to let the server now to break to the next line at that point.this project is a client/server application so just storing the text string and expecting flash to be able to use the same size text box will not work.
I have created a function that detects keypresses and MOSTLY takes care of the carraige return issue (still not as solid as I'd like though). Basically, every time the user presses return, I store the length of the string and, when parsing the data for transfer, I insert newline chars at every index point where one is needed. This mostly works unless the user goes BACK and enters a return (still working on that little issue).But the word wrap part is killing me. I did find several discussions of using either total characters to determine how big the box is and where to break the line, or something along those lines, but here's the main issue with that:everything is dynamic. the user can change almost everything, from text font (so there will be variable font widths) text size (again, variable widths) to textbox size (so I can't go with a fixed pixel size to break the text). I've noticed that it was very easy to make a text box vertically dynamic, but the width seems to want to stay fixed (if set to multi-line) since the user will be changing this width, I'm just stuck.
if it means coding a huge set of functions that compares every possible font (i will be using embedded fonts eventually so they will be limited) with every possible size and then using that data to determine box size, that's fine, I'll do whatever I can to get this working, but there just has to be an easier way
I have recently purchased Pageflip 3.6 (http://pageflip.hu/) for a project at work and what I am planning on doing is implementing a guest book which i have created in flash.The guest book I created consists of a file upload (for images) a comment entry and a signature section (where the user has a choice between a bunch of fonts and writes there name) which are located on the left page of the flip book and then on the right page it displays the post (using XML).
Now the guest book on its own works like a charm, but when it is called into Pageflip the buttons for the upload/submit stop working and nothing happens.The way Pageflip pulls in the swf/png/jpg to fill its content is through an XML file.Pageflip does have hot spots and controls to switch pages directly within the book but I have disabled them so that you can only switch pages through the control bar, as I thought the hot spots were conflicting with the input for the guest book but it didn't do anything it still will not allow me to use the controls for the guest book.
I know this might be kind of confusing I hope i described my problem clearly enough and any help or input at all would be fantastic. I'm fairly green with actionscript but i'm the only one at my agency that knows how to use it so its tough on me to do these advanced things without anyone to bounce ideas off of
I'm developing an iOS flashcard app in Flash CS5 for a school project. I've got over 600 scenes, and my cards are structured in pairs so that one scene is the front of the card and the next is the backside with the answer. I've figured out how to get from scene to scene, but have had no luck trying to find how to randomize scenes while keeping them in pairs
I'm having a conundrum. I am trying to duplicate the link effect: http:[url]....The thing about that is that I am trying to create this for an HTML site as link transitions for a client. My issue is that the swf has to maintain size on ALL browsers and sizes. I've tried setting the html object sizes to 100%, but the video is smaller. Is there something I'm doing wrong?
I am working on a project in which I am suppose to maintain an array of movieclips, and I can also convert the movieclips into bitmap data. So I would like to know which one is the best to use either maintaining movieclip array or bitmap data array.
I am going to be utilizing a flash/jquery powered gallery on a webpage that is maintained and updated with an xml document. The xml data is used to add and sort images into a grid of small thumbnail images. i will customize this component so that when the user rolls over a thumbnail it will trigger jquery to replace a div using hide/show. My employer would like to try to create an adobe air desktop widget that will mirror the content of this gallery so that as entries are added to the site users can access the content automatically via the desktop. I was thinking there may be a way to utilize the same xml document to maintain the app as well as the gallery. As there is a fairly tight turn around on this project, i was wondering if anyone could confirm that adobe air apps can be maintained in this way, or how to approach this particular client request.
I have a canvas component called myCanvas and I instantiated it with
var myCanvasPage:myCanvas = new myCanvas; this.addChild(myCanvasPage);
Then I want to essentially reload myCanvasPage later on. In effect I want to do this:
this.removeChild(myCanvasPage); var myCanvasPage:myCanvas = new myCanvas; this.addChild(myCanvasPage);
except instead of creating a new instance of myCanvas, I want to use the already created instance of myCanvas and essentially reload or re-create it but making sure that the instance name and references to it remain the same.
I have a TLF editable field in a(n) swf file. Text entered there gets sent to a php page where everything is processed. I had the behavior set for multiline, but just realized that if someone hits return and keeps typing, no break is displayed (not even a space). I've tried using nl2br() in the php when it grabs the POST variable from flash, but that doesn't work. I don't know how flash handles the carriage return, so I don't know how to handle it on the php side either.
I pretty much got it working. The only problem I'm having is that it's only full screen based off of the width. I want the picture to maintain it's scale, so I need it to fill the height if necessary and cut the sides off of the picture. You can see what I mean by clicking [URl]. Resize the browser so it's a lot taller than it is wide and you'll see what I mean. I want it to fit both height and width no matter which is taller. I've played around with it all morning and nothing.
Code: // pic_mc is the movieclip that I used to load my full-screen background image. function bgResize() { pic_mc._width = Stage.width; pic_mc._yscale = pic_mc._xscale; if (pic_mc.height >= _yscale) { pic_mc._x = (Stage.width)/2; pic_mc._y = (Stage.height)/2; [Code] ......
I'm trying to highlight the current 'page' / movieclip by showing the onrollover state in navigation display/button.So the colour remains the onrollover state (in this case blue) while the particular movie clip/'page' is displaying. Changing when the user rolls over another button.I have two issues:1. I understand I have to place the button within a movieclip and have been experimenting with button '02' in the attached example.fla - however now I have done this the original action contained within the movieclip instance myScreen_mc is no longer working.
