ActionScript 2.0 :: Preloader SWF Setup - Loading Images / Info
Oct 8, 2007
I'm about to make a preloader of sorts, but have run into a problem because I have multiple SWFs being externally loaded in different locations. [URL]
As of now, it's setup like so:
Main.swf - has the scrollbar, loads body.swf into scrollbar container
Body.swf - has the layout, buttons, etc. Loads illus_finished.swf, illus_sketchbook.swf, etc.
illus_finished (and all other work files).swf - dynamically loads XML and images/info.
So basically, its one big swf that loads the content swf. The content swf loads the work swf's - which load the xml, images/info. I think I might load all the swfs from one file somehow, but I'm having trouble targeting into MC's of loaded swf's.
Should I set up a preloader swf, and somehow preload all the swfs into the browser cache? (I dont know how to do this, esp since I'm loading into a target, and not a level#) This way I wouldn't have to change how my movie is setup.
Should I take all the loading instances out of all my files and load them all from the first movie - and stick the preloader in THAT file? I can't figure THIS out, either, because I can't seem to target movieclips in loaded SWFs.

I have a page display people's name and when you click on a name information such as age, height, and weight are displayed. In Flash, can you create the same thing? I know with displaying data from a database you have to have dynamic text boxes set up to load the info but can you have it set up so you can load a name from a database and THEN click that name to have it load the other info?

I've constructed a dynamic slideshow using ActionScript 2.0 and PHP/MySQL. The reason for this, aside from update purposes, is that the slideshow will eventually display over 200 images. Thus, to save loading time and bandwidth, I decided to use PHP to pull ten images from an SQL database, formatting the output in XML. The slideshow itself works fine. Unfortunately, there are a couple of issues I need to address; my ActionScript is extremely rusty, so much of my work's patchy.
The code's displayed below:
import mx.transitions.Tween;
import mx.transitions.easing.*;
var myShowXML = new XML();
myShowXML.ignoreWhite = true;
myShowXML.load("getData.php");
[Code] .....
The code in red is my main focus. It's the loop which loads all images as movie clips using the XML information from an array. The loop loads all of the images, making them transparent before the presentation begins. What I would like to do instead, to save loading time, is to load the next image while the current one is displaying. The function "moveSlide" controls the transition of the images, so I'd imaging it'd be best to plade it in there.
There's already an incremental variable being used, with _root.target_mc, for removing transparency from the current slide. The code in blue is also nagging me quite severely. I retrieve the next chain of slides by simply contacting the PHP script again. The only way I could think of doing that was to refresh the slideshow (this is done COMPLETELY in ActionScript, with nothing on the stage). Unfortunately, I could only work out how to reload the whole video.

I'm using a bulk image loader from FlashAndMath. The code has you send a list of images to load and it simultaneously attempts to load all at once, adding each load req to a list.
My problem is that when one doesn't load and throws an error, I don't know which load request failed. Are there built-in ways to get it to report what image it was trying to load, or at least which of the load requests threw the error? I tried doing an event.contentTarget.content.name and it reports an instance #, but not the name I tried assigning when I called the URLRequest.

First of I'm using Flash CS4 and AS 3.0 I'm trying to make a photo gallery for my website. I have the gallery all setup and made and now I need a preloader for loading my images. Right now my gallery is setup like this:
-A list of clickable thumbnails. (20 thumbnails)
-A UILoader
-You click a thumbnail and it loads an external image into the UILoader.
Actionscript: I have an array with 20 images. I have 20 different event listeners for each thumbnail.
The eventlistener looks like this:
thumbs.thumbs1.t1_btn.addEventListener(MouseEvent. CLICK, loadP1);
The function looks like this:
[Code]....
The UILoader is inside 2 moveclips because of a transition effect I have. The buttons are also 2 movieclips deep because of motion tweens.specific reason.

I created a flash slideshow which preloads the images. After preloading the images, it proceeds to load an external flash file and then the images. The problem is, very very occasionally, it will fail to actually load the images into view, and I'll just see the preloading animation, but it might still load the external swf. Additionally, it might do the reverse, and load the images and not load the external swf.
Here is the (I think) relevant code:
function onXMLLoadComplete(e:Event):void {
// create new xml with the received data
xmlSlideshow = new XML(e.target.data);
// get total slide count
// misc xml data
[Code] .....

I'm building a flash based site for my photography in Flash CS3 with actionscript 2. The swf is almost 700kb so I guess I'll need a preloader right? I thought I could create a preloader scene before the main content scene and apply the following code to the single frame within the preloader:
Code:
ifFrameLoaded ("website", 3){
gotoAndPlay ("website", 1);
}
This doesn't seem to work as the large images in my gallery (contained within a movie clip) won't load unless you leave the gallery page then go back in?

I have a gallery, which loads up all its images from an XML file. So the XML gets loaded, when loaded it calls a function urlLoaded. That in turn puts uses a Thumbnail class for each image in the XML, which then gets placed in an array, so the array can be iterated through to establish X and Y pos of each image when added to the mc Photocontainer.
PHP Code:
var urlRequest:URLRequest = new URLRequest("pics.xml");
var urlLoader:URLLoader = new URLLoader();
var xml:XML;
[Code]......
I'm passing the parameter 'i' through to the tracel function as this traces when each image has finished loading. I have a preloader in the main timeline I want to control. Say there are 20 images, how do I use the info in the tracel function to control that preloader? Would it be best to pass into the Thumbnail class the xmlList.length(), so the number of total images and then from the tracel function add and control a preloader, so when image 10 is complete the tracel function would make a slider its added to stage go to half way.

I'm using TLF text, so there's a RSL involved. I get that there's a way to include the library in my own code, but I'd rather not do that unless there's no other solution.
In Advanced Action Script Settings > Preloader Method, there's a choice between "Preloader SWF" (five black dots, the default thing) and "Custom preloader loop". My first question is then how to use this Custom preloader loop thing? What is it referencing? Do I have to write a special thingy somewhere? What?
And I already made a simple "bar filling up" kind of preloader, which I'm testing by using the aforementioned "Custom preloader loop" setting and simulating download. (My project no longer compiles when not simulating download [VerifyError: Error #1014: Couldn't find flashx.textLayout.container::ContainerController class.] which led to the conclusion that I'm doing something wrong here.) It does fill up, but it starts at about 60%. From my earlier badly worded Google searches, I think my problem is that I am using a bunch of external .as files which are loading before the preloader. Is there any way to tie the .as files later, or something?(That, or my preloader actually takes up 60% of the project's data, which would surprise me but isn't impossible because it's still very bare.
I'm making a game and I'm sorta kinda using tiles to render the map screen. So I have a bunch of sprites on screen, for which I created a Refresh() method that I call whenever necessary. In this method, I use a Loader object to load desired bitmaps (which aren't in the project's Library), then add this Loader as a child. The main reason I did it that way is because I could then reference the images to load with a string, and so include arguments in there.
(I don't know if I'm clear, so let my try to be more descriptive. I basically have an array containing the map data. I'll read that array and pass some properties as arguments to my Refresh() method to draw the screen correctly. I'll then be able to load the image ["sprite" + arg1 + arg2 + ".png"] by using that string to create a new URLRequest (and then use that in the Loader).If I understand the way this works correctly (and I probably don't ), I'm downloading the images all over again each time I call Refresh instead of having them "cached" somewhere, which is inefficient (because they're tiles and I'm reusing them multiple times). Am I correct in that assumption?
I thought the more "efficient" way would be to import my tiles in the project Library and export these for ActionScript. (They're PNGs, so they inherit from BitmapData.) My problem with this method is that to use these images, I now have to instantiate a class, so there's no string involved, and so I can't concatenate variables with a string anymore to fetch the right PNG to display, which is really, really annoying.
So I'd like to have the best of both worlds: cache images while still being able to refer to them with a string. Is that possible? And more generally, what's the "right" way to dynamically render images in the context of a tile-based map?
EDIT:public vars vs. getters and setters I have classes with properties. I've gathered that it's good programming practice to declare these properties as private vars and then define getter and setter functions to access them. It's easier to just declare these variables as public and move on. What are the pros and cons of both methods?

I'm very new to flash and have a question for you wizards
I've created a simple slideshow displaying images which are being loaded from a XML file. I wish to have a preloader which displays the % loaded , if possible, while it's preloading the images from the xml file.

[code]Whenever im preloading images, i get a NaN Error everytime. Sometimes all i see is a NaN error, not even load numbers like 89% or so. I got the swf online at url...If you go to any section in the designs menu (3d design, 2d design or webdesign) and click a image you get the script that gives the NaN.I only get NaN in Firefox, Internet Explorer just gives 0. But either way i would like to see percentages rather than 0 or NaN.

I have a rotataing menu that is driven by xml images. the images all load in, but I would like to have a little text info at the left side of each image as it rotates.I understand that you create dynamic text fields, which I have done in my fla that then somehow link you to the xml where the text info is read from, but how the AS3 script goes for this I do not know?I would like the text to be fixed with the image and rotate by the side of images and not pop up like a tooltip.I am working with example files I received from soulwire, which contain displayObjects so I think it has to be done like that?I am new to AS3 so I don't really understand how it works, would anyone beable to direct me to somelinks on how to do this or be so kind as to take a look the example files I have uploaded.URL...

I'm making an image viewer which loads in the images and their info from XML. I'm wanting to have a list of the images titles, and clicking on a title brings up that image. I've parsed the XML into an array, and I'm using a FOR loop to go through the array and create a project_btn sprite, which contains a project_txt textfield within it to display it's name. As part of the FOR loop,I'm adding an event listener to listen for a ROLL_OVER event,which, for the moment just traces the project_btn's name. The problem I'm having is that it seems to only add the eventListener to the LAST project_btn... so the others are useless. [code]

I am trying to create a news rotator that pulls info and images from an XML file.I made something similar a while back which pulled just the headlines which worked great and I am trying to adapt this same idea to a current project. pull all the info from the XML and push them into separate arrays based on the type of information it is. ie title, description, image etc.From there I have a function which is supposed to display the all of the info and another which cycles through it based on a timer.Like I said before, this worked great with just the headlines, but when trying to add images its getting thrown off. The function which intends to parse the data and pushing it into separate arrays.
Code:
function onLoaded(evt:Event):void {
xml = new XML(evt.target.data);
var il:XMLList = xml.channel.item;
[code]....
I'm aware that it has something to do with either how the info for the images is being parsed (or not), and/or how I am going about displaying it.I was able to write a separate function which displayed one image as intended, but then wouldn't cycle through as the news changed.

I am trying to load variables from my webpage onto my .swf
ActionScript Code:
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, loading);
[code]....
This code works perfect for loading variables in a &var1=1&var2=2& etc...But how can I load variables from the page?like do I need to put in &array_name[incrementing_var]=value& and then when i go to access it it should be loader.data.array_name[0] but this doesn't work for me? I realize my URLLoaderDataFormat.VARIABLES is for variables but can i still pass arrays with this? or do i need a new format? or do i need to pass the values as variables and convert them into an array in my AS?

I have some scrolling content (info). I've also made my own scroll bar.I want the scrollBar dragger to be positioned in relation to the info._y as the user scrolls info.I have created two vars: one that worsk out where info._y is as a percentage and the other that works out where the scroll._y dragger should be as a percentage...
Actionscript Code:
var scrollBarPercent = Math.round(scrollBar.dragger._y / [code]........
also onMouseWheel working too.I need a small bit of code that takes the % of info._y and moves the scrollBar dragger to the same % but in relation to the Stage.height...so if projectGalleryPercent = 50%, make dragger._y 50% of Stage.height using scrollBarPercent.

I have a rotaing menu that loads in images from an xml file, I would also like it to load in text info from the same xml file to the left side of the images that load in. In my main .fla have created a movieclip and called it 'textInfo' and inside that I have two dynamic text fields called 'headerText' and 'bodyText' where I want to load the text in. this is what I am using to loading in the text in my actionscript, is this correct?

Explaination: MX 04' Pro Thumbnail Nav. loading images with XML Loader resizes and displays images when users click on Nav. reading XML Problem: Users click Thumbnail Nav. first image gets loaded and loader resizes to image. However the next choice by user on thumbnail click, the second image doesnt get resized in the loader. It goes beyond holder. Here is my code for Thumbnail and Loader:
[Code]....
Now the first image loads fine and the loader sizes to file from XML. However, when users click second choice from Thumbail the loader doesnt resize to new image size. It only gets resized on the first selction or if users click the next or prev. buttons then the images fade correctly but nothing fades back in. Now if they do hit next or prev and then hit a thumbnail option it loads and resizes.

I need to load dynamically a few images (4-6) so that by clicking on particular image user would invoke particular action. Embedding images solves the problem but at the expense of file size. If I load them dynamically, they lose their ID.

I want to have an AS3 app load images from url supplied by the user. But I don't want a malicious user to be able to load an SWF file in place of the image, such as with an altered extension "maliciousSwf.png". Well, not sure how big a security threat that is above and beyond the ability of the hacker to decompile swf, but I think that ideally such behavior should not be allowed.
So, is there any way to prevent this? When people allow users to load images in their Flash apps, do they somehow guard against loading of SWF? Or is this really absolutely no big deal?

How would you defer loading of other graphics on the page until after the images in a Flash gallery's images.xml file are finished loading?Is there any way to detect for this, or would I only be able to check if the flash swf object is finished loading? I'm pretty sure the swf object would be loaded/ready as with document.getElementById('flashobject').onload = function(){}; before the corresponding images have loaded though, instead of after.
