ActionScript 3.0 :: Checking Whether A Loader Object Is Loading Something
Aug 7, 2009
Is there a way to check whether a loader object is in the process of loading something? I need to create an if statement that checks if the loader has an open connection. So far, what I thought of is:
ActionScript Code:
if(loaderInstanceName.contentLoaderInfo.bytesLoaded > 0)
{
// do something
}
Here, I'm just assuming that if bytesLoaded is greater than 0, than it's probably loading something. But I don't think it will revert back to 0 after the loader finishes loading an external resource. So after that, bytesLoaded will always be greater than 0 even though it isn't in the process of loading anything. Is there any other property that I can use which says whether the loader object has an open connection?
I'm trying to get smoother steps in checking the ProgressEvent when loading the image to the Loader.At this moment my eventrogressEvent checks the progress aprox twice within a second. Is there any way to make it check constantly (or more often), so the progres bar "grows" smoothly instead of "jumping"?
I loaded 5 JPG's into specific locations of an array via the URLRequest. So now when I trace my array:
[Code]...
THE PROBLEM: when I scan getXMLlinksArray and see that its NOT null, and i try to addChil to xmlImgHolder and then to spriteHolderArray, I just get a blank space. The debuger is showing that spriteHolderArray contains some loader info and the appropriate URL up until I load it with the existing loader from getXMLlinksArray. Then it says it doesn't have any conentedLoadedInfo.
I am attempting to load multiple images in AS3 and I'm exploring different options on how this can be done.I would like to have to only use one Load() instance and handle the various image assignments in the onComplete handler...here is my first attempt:
var buttonLdr:Loader = new Loader(); buttonLdr.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onLoadError); buttonLdr.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadCo
Sorry for the complicated topic. I got a .swf that loads in other .swfs. Rather than figuring out how to make a loader for loading .swfs I thought I'd just use a simple loader in the .swf I'm loading.
However, it doesn't work. It starts fully loaded but doesn't finish. Heres the AS:[AS]_root.stop(); PercentLoaded = _root.getBytesLoaded()/_root.getBytesTotal()*100;
So I have this Photo class than handles loading a pic, and dispatches an event when the loading is done with:[code]which is simple and works, but now I'd like to make something more advanced. I'd like to dispatch the load ratio.So far I have extended the Event class, with my own EventRatio class, and I can put properties on that class. Which is cool, but I need something more dynamic than just sending a fixed value.So, what is the best way to connect the Loader object of the Photo object, with the EventRatio object?
In my script I create a button that when clicked, creates a blue square. However, I want to remove any blue squares that exist before creating the new square (because as it is a low opacity square creating another one will make it more solid, as well it's just more objects that the system has to keep track of).Here is my code:.as
ActionScript Code: package{ //importing required classes for this to work
How can I check for the presence of something on the stage? I want to disable mouse clicks on the currentTarget while an image is loading, and I'd like to use the presence of a progress bar as the determinant to proceed.
Code:
If (progressBar is somewhere on the stage) { currentTarget.mouseChildren = false; currentTarget.mouseEnabled = false; }
in AS3 to check if a file exists before loading it. There was not very much about so I wrote these classes to do it. There are two classes, the FileLoaderUtils and the UtilEvent. the FileLoaderUtils has the function doesFileExist(url:String) and when called the class uses the URLStream class to attempt to load the file. If the file exists a UtilEvent.FILE_EXISTS event is dispatched. If the URL is incorrect or the file doesn not exist a UtilEvent.FILE_NOT_FOUND event is dispatched.
I wrote the following code to check memory when loading a big image (~20Mb). Every time I do mouse click, the application eats up memory, so something doesn't get deleted or cleaned with GC but I can't figure out what exactly.
imageLoader.as PHP Code: package { import flash.display.Loader; import flash.net.URLRequest; public class imageLoader { var fname:String [Code] .....
I want to do something like this in Actionscript 3:
if(variable is Object) ...; else ...;
Where variable could be a String(), Number(), Array(), Object()...Currently the above check returns true for all of these types, which makes sense. I only want it to return true for objects made with new Object(), however.
I have a spinning sphere, built using the away3D engine, it is wrapped in a bitmap. I need to be able to check the color value of the pixels in the sphere, however BitmapData only plots the 2D image, not the 3D sphere. So, the values become wrong. If I try to apply it to the sphere I get nasty errors. I have literally been stuck on this for days.
I've got to build a kids game at the moment for my school, and I was planning to have a sort of archaeological dig, with the kids required to rub the screen (it's for a touch-screen) to "un-earth" the bones underneath.I was thinking of either erasing an overlay and checking for a hitTest between the two objects, or coloring in with a line or something.Is it possible to color something in and check when the object has been completely colored? or possible to erase an overlying object? and if so, can you point me in the direction of a tutorial or a quick explanation?
I'm attempting to make a platform game. Each level is contained within it's own MovieClip, which has it's own class. Each of these classes extend the Level class, which provides basic functionality for all levels.
Each individual level has a numPlatforms variable which stores the number of platforms in that particular level. I currently have a for loop that runs from 1-numPlatforms and sets the level area (the image, more or less) the platform contains:

Is there any way to check if a variable exists within a MoveClip? I've trying comparing it to null and also to undefined, but neither works.
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?
im working on an image viewer and im loading an image to a loader and then add the loader to the stage.I want the user to be able to drag and drop the image but since it's a loader i dont know how to do it. I tried
In Actionscript 3, I'm trying to build a button to go back from a content frame to a main menu. When the button is clicked, IF the content frame has a movie in it, that movie should stop playing. Flash keeps throwing a "null object reference" error on all pages that don't include a movie. I even tried putting in a check to see if the movie exists, but that doesn't work, either.
ActionScript Code: function return_to_menu( me:MouseEvent ):void { if ( flashmo_contents.flv_movie ) { //this line produces errors in frames where the movie
I am doing my first all out flash site without a template and tried several different ways to load a external swf file to the site vie ui loader... it works fine on my local computer but when i put it online the external swf doesn't show at all while the rest of the site does, and im not getting any error..
I've set up a swf with three buttons and when you click on one it loads a different swf and places it into a movie clip. If there's already something in the movie clip it removes it and then replaces it. The problem I'm having is if one of the swfs is very large and for whatever reason someone clicks on a different button where the swf is smaller it will load the smaller swf but continue to download the larger one and when that finishes it will load on top of the smaller one.Here is my code:
ActionScript Code: var home:MovieClip = this; var ldr:Loader = new Loader();
I have a flash animation made on the main timeline of the SWF with a couple of layers, some functions and some keyframe labels. For example, i have a movieclip of a star that come across the screen and then trigger a dispatchEvent for the main timeline to go to frame label "next".[code]That SWF alone works perfectly. Problem come when i try to load this SWF into another one. What happen is the loader keep reloading the SWF over and over, overlapping them and the actionscript that's on the main timeline of the loaded SWF is ignored, the timeline plays continuously. Here is the code i use to load the SWF.[code]I have found a workaround by putting the entire animation inside one main movieclip and put that movieclip on the main timeline (one keyframe, one layer, no actionscript) and then load it. That way it works fine but it feel more like a patch than a solution. I would really like to know why it's bugging when you try to load an external SWF that use the main timeline with multiple layers, keyframes and actionscript.
I have a Master SWF that has several buttons on it's stage.These buttons each load a remote SWF of a clickable graphic into the Master movie's upper left hand corner. Inside these loaded clips are several clickable areas that I would like to use to load yet another movie into the bottom half of the Master clip ... so, it's loading a remote SWF onto the stage of a third party.I'm having a simple targeting problem. I'm not quite sure how to call a movie to load into a loader on the stage of a different movie clip. I'm using "parent" ... but i got something wrong:
_________________________________ var unitSwfLoader:Loader = new Loader();unitSwfLoader.x = 25;unitSwfLoader.y = 390; function getUnitSWF(e:MouseEvent):void { unitSwfLoader.load(new URLRequest( "units/"+ e.currentTarget.name +".swf" ) ); parent.addChild(unitSwfLoader);}
I've tried adding this loader as a child of several different sprites but it only ends up in one of the sprites (must be removing from the other sprites display list automatically).How can I duplicate that image in the loader into multiple sprites?e.g. (note don't worry about making sure the icon is loaded, pretend I wanted to Event.COMPLETE before adding to
var icon:Loader = new Loader(); icon.load(new URLRequest('image.png')); var iconA:Sprite = new Sprite();
I'm using the following code to load an swf in a pure actionscript project (Flex Builder 3)
_loader = new Loader(); _loader.contentLoaderInfo.addEventListener(Event.COMPLETE, Loader_Complete); _loader.contentLoaderInfo.addEventListener(Event.INIT, Loader_Init); var request:URLRequest = new URLRequest("Skins/TestSkin.swf"); _loader.load(request);
[Code]..
I have seen examples online where people say these work for them but whenever I set width or height in any of these ways, the loaded swf is simply not displayed at all.
when I run the code there aren't any errors stopping it from compiling correctly. However when I click on my buttons i get an error saying:
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
I'm guessing that I'm passing the variable off through the function incorrectly. I'd like it pass a string though so that I can pass the name of the file to load.
ActionScript Code: function contentScreen(mcName):void { var imageRequest:URLRequest = new URLRequest("mcName"); var imageLoader:Loader = new Loader();
I have a flash file with a 200 meg video file in it. I want to run a pre-loader and indicate the file is loading. I have a stop action script built into my first keyframs and on a seperate layer the following action script:
I am creating an image gallery where the user can select from several thumbnail images. Once selected, the thumbnails will enlarge and load the full sized image. My problem is that while the user is waiting for the full sized image to load, he may decide to close that image and view another image. I am trying to find a way to stop a loader from loading. Here is the code I have used. My problem is that even though the user has clicked on the unloadBtn, the loader continues to load the file. Is there a way to disable that?[code]...
I have a loader, and it doesn't seem to be loading my content when I am viewing it on my website. However, when I open up my loader.swf in a browser, it loads up my content once it is done loading.
Loader AS3: var loader = new Loader(); loader.load(new URLRequest("slideShow09.swf"));
