I need to have scrub thumbs for video player load and unload repeatedly.
Something isn't getting cleared. Every time the thumbs are removed, there's a slight increase in the cpu baseline - something is piling up in memory.
Below is the relevant code:
Code:
function showScrubThumbs():void {
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
xmlLoader.load(new URLRequest("testThumbs.xml"));
}

I have 3 buttons layed out in my design (more to come ultimately). Once you click on any of these buttons, they will add their corresponding movie clips to the stage (button 1 will add movieclip 1 to the stage, etc). Each of these movie clips are details of a project (I'm building a portfolio). Some of these movie clips will have Loader classes in them, loading external images into them for a slideshow.My problem comes in removing any previous movie clips from the stage when a new button is clicked (eg. click button 2 - movie clip 2 shows, click button 3 - remove movie clip 2 before adding movie clip 3 to the stage). I got it to work sorta, but the biggest problem comes with movie clips that have these Loader classes/images in them. When you click back to that project, you still see the last image loaded in that movie clip (like it was not cleared or reset when removed from the stage). How do I remove movie clips and all of their loaded children dynamically, while controlling them with buttons. Here is my sample code (the "showclip" function is where I need to fix my logic).
//Add the Nav Buttons to the stage
var btns_mc:MC_Btns = new MC_Btns();
btns_mc.x = 0;

I'm loading an xml and creating thumb buttons from it. I loop through the xml list and add thumb clips to a container clip and add the loaders as children to the thumb clips. I store the loaders and thumbs in arrays. When I need to remove the thumb clips, do I just remove the thumb clips? Or do I need to unload the loaders first, then remove the thumbs?
View 3 RepliesIf you have multiple event listeners running, is there any way to remove all of them at once rather than one at a time?
View 3 RepliesI have a basic question about manually removing event listeners in actionscript 3.If I have a function like:
private function doStuff(event : Event):void
{
//let them save
var f:FileReference = new FileReference();
[code]...
How do I remove the event listeners when the saveDone function is called? Normally I just change the "add" to "remove" like:
f.removeEventListener(Event.COMPLETE,saveDone);
However, f is a local variable, and I can't get to it after the doStuff function ends.
private function saveDone(ev:Event){
f.removeEventListener(Event.COMPLETE,saveDone);
}
I'm trying to do something that I'm not sure if it's possible. I have to add or remove multiple listeners that will trigger the same three methods (onComplete, onError and showProgress). I was trying to do something like this:
[Code]...
Is there anyway to solve this? It seems that after passing through the addListeners method, the loader instance gets lost.
I was just wondering--and it's probably an obvious question really--if I make an object null and that object had one or more event listeners registered, are the listeners removed?
for example:
Actionscript Code:
object.addEventListener(Event.SOME_EVENT,callBack);
function callBack(evt:Event):void
{
object = null;
[Code].....
In this case have I removed 'object''s listener when I made the object null?
ive made a flash website containing 5 pages all accessed via flash buttonson one of the page ive tried loading a external swf file and then added event listeners to each of the buttons so when a new page is selected the swf file doesnt continue to play in the background on the other pagesthis works, however when i then try to change page again this error is displayed:ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display:isplayObjectContainer/removeChild()atValleyViewingWebsite_fla::MainTimeline/btnClick()below is the code im using:

I'm creating a class for a game, and I'm having a problem removing event listeners from movieclips in that class.In the class file I have an enterFrame event which puts the movieclips into motion - I want to remove that event listener when the movieclip is removed from the stage.I made the function 'public' in the class file and tried to target it as follows (animal is the movieclip)animal.removeEventListener(Event.ENTER_FRAME, animal.onEnterFrameHandler)
View 2 Replies I have l modded some code that I am really happy with, it makes buttons bounce around for the user to try to click on when entering a certain frame.. I notice tha the code adds eventlisteners ENTER_FRAME to make this work, when you leave that frame there are now problems with null objects becuase the listeners are still on but the objects are not there anymore..
Ok so attempted solution - I can use a currentLabel on the main timeline to check if the correct frame is reached then use a function if (label is x) put listeners on else take them off... works but then I have to have these objects hidden on the timeline and then add visible=true/false to my framelabel listener.. This works but part of my functionality here is that these movieclips that move are buttons that the user clicks on and they explode and dissapear- but now they dont because I have a code that says on that frame they should be visible..
The only thing I can think of is to have a blank frame at the end of the explode and put a stop on it. Then add a gotoAndPlay(1) into my frame label code. Seems very ugly, you guys got a better way? Can I remove eventlisteners on leaving a frame? Is there a code like LEAVE_FRAME??
Do you have to remove event listeners on variables with local scope? By this I mean...does the event listener still exist if the variable only exists as long as the function/method is running?
private function startSomething():void
{
whatever.start();

I'm adding and removing stage event listeners I am relatively new to AS 3 and have been building a liquid layout site unfortunately I do not have a strong grasp of classes and have been doing all of my scripting on the main timeline with encapsulated script within MC's.
basically I am calling on the same functions over and over and those are mostly resize functions which I have added StageEventListeners on the appropriate frames to listen for resize events on that stage now as of now I have literally dozens of these scattered about the site. when testing my site things are running fairly smoothly however I keep getting error messages in my output window that go a little something like this.
[Code]...
almost every single one of my classes, starts with the same method. An event listener in the constructor for EVENT_ADDED_TO_STAGE. Then i do all my actual intialising in a beginclass function that listener runs.I've not generally been removing these listeners though. i never thought it would make a difference since i'm only adding these objects once, but i wonder if there's a performance element. it could be for example, that all of these listeners add an extra check each, ehenever any object is added to the display list.
View 1 RepliesI'm trying to develop a catching game, just for a bit of fun and learning experience. I've been bouncing between tutorials and I've finally come to a point where I can't get any further. After you catch three sandwhiches, you lose and it takes you to an end screen, however, I'm unable to stop the listeners from being called, and when the game restarts, the food falls, but you're no longer able to catch it or keep score.

I've created a drop down list and populated it with dynamic buttons. (I made a DropDown_btn class with a dynamic text field in it and then filled the button text from an xml file). On rollover I tint the button blue and then set the tint back to black on rollout. When you click on the button I'd like it to stay blue until a different button is clicked.
I thought on CLICK I'd run a function like this:
ActionScript Code:
function removeRollover(evt:MouseEvent):void {
evt.target.transform.colorTransform=c;
evt.target.removeEventListener(MouseEvent.ROLL_OUT, btnOut);
evt.target.removeEventListener(MouseEvent.ROLL_OVER, btnOver);
}
...and then I need to addEventListeners back to any button that doesn't have them and set that button back to black. I could do this by looping through an array of the buttons but I can't figure out how to access them as objects.
I also gave them each a property of "buttonValue" when I loaded them so I can access event.currentTarget.buttonValue (which in this case is a number from 1-5) but once again I can't figure out how I might leverage this information.
I want to make a static function that I can use in all the custom classes.It should be some kill(); function that would remove the object from the stage as well as removing its event listeners. I made it in Document class, and it didn't work. Here's the code:

public static function kill(e:DisplayObject)

I have two components in my movie,how to write out the code for the listeners.Is it possible to write one listener that listens for changes in both components or do I have to write a separate listener for each? How would this look like written out?
View 1 RepliesMy main project loads an external .swf ("room") depending on which button the user clicks. Once that external .swf ("room") is loaded, the viewer chooses a ("demo") .swf to view. For each button click, a loader is to appear showing the viewer that the desired room or demo is loading. All of this works fine for the web...please click the link below to view.
The problem exists when I try to publish as an .EXE. We'd like to send these out to prospects on CD and thus I need an .EXE to autorun when insterted in a PC. I've published the main .SWF (overhead map) as an .EXE and burned a cd containing all necessary files. Now when the user clicks a room and then a demo, the loader that shows up fine on the web does not appear...the button stays in the down state until the demo .swfs loads and then the demo appears and plays.
I'm making an image gallery and am loading about a dozen thumbs that load a larger image when each one is clicked. Works just great so far. But, as expected, there's a little pause before each corresponding large image is displayed.I'd like to eliminate the wait, if possible, so here's my question: As a matter of preference or programing style, whatever you want to call it, do you guys usually load ALL the images first, thumbnails as well as large images, before displaying anything on the stage? Or do you just load each large image when necessary, after its corresonding thumbnail is clicked?Sometimes I see very cool Flash sites that have the percentLoaded line or twirler displayed for what seems like a long time, but then each screen (MovieClip) after that displays fairly quickly and I'm wondering if that's what's happening - all, or at least a LOT of the images are being preloaded

I've got a swf loader that loads a swf obviously but in the swf that's being loaded I have a button inside of a movie clip which I use...
Code:
on (release) {
_root.gotoAndStop("page1");

When viewing the swf file on its own this works perfectly, however when it gets loaded into the first file it no longer works because the root has now changed to that first file.
I am making a web page and i have to load in to main page swf multiple swfs that represent background. First there is a gradient swf than swf with snow particle system. My question is what would be best practice to use one loader for all different swfs that are in the background or should i use different loaders for different swfs?Here is what i mean:
1.) var loader:Loader = new Loader();
I use this loader to load first gradient swf and after it it has completed loading i use same loader to load snow swf.
2.) var loader:Loader = new Loader(); + loader = new Loader();
I use this loader to load first gradient swf and after it it has completed loading i set it again to be loader = new Loader();
and than i use this loader to load snow swf.
3.) var bgLoaderGradient:Loader = new Loader(); + bgLoaderSnow:Loader = new Loader();
I use it to load gradient swf and than i make new loader,
bgLoaderSnow:Loader = new Loader();
to load snow swf.
So what would be best way to do loading of the swfs.
I have a project that needs 4 levels of zoom, each with its own image loading in. So, to make things easier on myself, I made an array of the Loaders, so I can instantiate them and hide/display them when I need toHowever, this doesn't work as I had expected. I.e. (using just two level for simplicity):
Code:
private var photo:Loader;
private var photoLarge:Loader;

I need to load and unload thumb buttons with images loaded in them. I load an xml, create the clips, then load the images into the clips.
When I remove the clips, I need to unload the loaders first?
Can I store references of the loaders in an array and use the array to unload them?
How should I delete the clips? removeChildAt()? Or use an array?

I am trying to load an image, with descriptive text and a back button on the click of a thumbnail of the image. I am using a MovieClipLoader instance to do this.
Here are my problems: I tried loading the image, with the text(which is within an external swf), using the same loader, but since I am placing them dynamically, depending on the dimensions of the image, I need to pass variables between the two. The image loader is taking longer than the text (obviously) but I need the dimensions of the image before I can place the text. How do I do that??
2. I tried using two loaders, with separate listeners, and the problem once again is that the text loads before the image, and is hence placed with default values instead of the values derived from the image. The code is within onLoadInit(). Is it possible for me to get the dimensions of the image from onLoadStart()???
3. There is a back button within the text.swf. I want the image and the text.swf to be unloaded when this button is clicked. How can I achieve that? Can I call loader.unloadClip(target), from within this? Will it recognize the variable?
