ActionScript 3.0 :: Clearing Out Object In Holder?
Sep 2, 2009
I am trying to create a flash visual showing a time series of data on a world map. I have created a flash file which 1) creates proportional circles for each country of interest (in this case 6 countries) and 2) has a timeline so that the circles change through time. I have successfully gotten the timeline to work with the proportional circles, however the circles to not clear out before displaying the new circles when adjusting the timeline. I am not able to figure out how to properly clear out the circles. I have tried using the holder.removeChild(c) command before I create my new circles, but get an error which states 'Parameter child must be non-null'.
ActionScript Code:
import XMLLoader;
import ProportionalCircle;

Here is the flash file I am working on for a local kids charity so you can see [URL]. If you press the next button 9 times it will bring you to a drag and drop game I have made, you have to match the targets so it spells cat, this works fine, the problem I am having is that the objects you match stays there for the rest of the frames (try it yourself by pressing next) I am just wondering how to clear this?

If I have declared my vectos object as such ActionScript Code:
private var _delsUI:Vector.<Single> = new Vector.<Single>();
fill it with data like:
ActionScript Code:
_delsUI.push(newListing);
Then later on I decide to use this:
ActionScript Code:
_delsUI = new Vector.<Single>();
Will this essentially destroy all objects and prepare them for GC if there are no other references any where else? or do I have to loop through the entire Vector and delete and set null each object?

[URL]I got it working but the problem is, is when i go to the next frame the items that are matched succesfully stay there, I want to know how to clear them, so they don't get in the way of the next frames.

I am trying to remove an event listener on a FileReference object by calling a function, but it seems not to be removed, and I do not understand why.
Here is the code:
private function clearFileUploadListeners(file:FileReference, index:String):void {
var dispatchEvent:Function = function(event:Event):void {
dispatch(event.type, event, index); };
file.removeEventListener(Event.COMPLETE, dispatchEvent);
var bool:Boolean = file.hasEventListener(Event.COMPLETE);
if (bool)
trace("ERROR");
}
When I run this code, the trace actually happens. I don't understand why this boolean returns true, when I just tried to remove the eventListener just above! I believe it has to do with the fact that the dispatchEvent function is defined inside another function when I add the listener:
private function upload(file:FileReference, index:String):void {
var dispatchEvent:Function = function(event:Event):void {
dispatch(event.type, event, index); };
file.addEventListener(Event.COMPLETE, dispatchEvent);
}
The problem is that I need to access this "index" variable from the listener, and I can't set it as a global variable as each file has it's own index and it's a burden if I have to extend each event class to keep track of the index (Event, ProgressEvent, ..). I actually found a temporary solution, I am not sure if it is the best! I put my removeListener method actually inside the upload method, but made it a variable. As AS3 allows dynamic object, I attached this method to one of my object, and so I just call the reference to the method when necessary. The event is actually removed.

When I'm disposing a sprite which has drawings on its graphics object, Do I need to use "graphics.clear()" or is "mySprite = null" is enough?

I'm having an issue where I have a holder swf that loads an other swf. I want to call functions from the other swf in the holder. I'm not as fluent in AS 2.0 doing this and it has to be done in AS 2.0.

I have a master SWF which has a menu and loads other swf's into holders so they can be animated. I have button's in one of the loaded swf's but i am unable to make these buttons alter whats in the main swf. I.e. addEventListener to button and root(but the root doesnt seem to root to the holding swf).

I want to create a page for viewing JPEGs and SWFs. There will be a holder and underneath this there will be a row of thumbnails. On release of a thumbnail the JPEG or SWF will load into the holder. The files need to be updateable.

I searched previous posts last week about this and learned that I can load a movie clip from the library in a blank mc holder similar to how I load an exernal swf. But so far that code is not working for me. I also need a way to close/make invisible the clip on user clicking an X. I have a page with about 6 key words over which I will place invisible buttons. First button instance is named compworkBtn. I have a blank mc on the stage, name of mcLoadertop. My mc I want to play is in the library and named compworkMC. I read that I need to set the properties to export and I have done this (picture attached for compworkMC).
[Code]....
Then I want the user to click on the X or close button and it goes away. I thought the easiest thing for this work be to program the Close button itself to drive the MC to a frame that had no content. It will still be there, of course, but not be visible. Then the user would click on the next key word and the next MC will load. Not sure that is a good solution though, because they will both still be there. So, I'd like a suggestion for another solution to unload the first mc and load the second one. I have done a similar thing with external swfs, but I will need a close button instance for each of the unloads, right?

What I've got is a holder swf that loads in a separate swf. Within this loaded swf there is a button, that when pressed, removes itself (as in, the swf the button is placed within is removed) from the holder swf and loads in a new swf.
This seems incredibly complicated to achieve, at least I think it is
What I've got so far is this, the holder swf...
Code: Select allpackage {
import flash.display.*;
import flash.net.URLRequest;
import flash.events.*;

how to center an image that is smaller than its attachMovie parent. Basically I have a blank slide (a 94 x 94 square) that I load dynamically image thumbnails into. Some of them may be 92 wide and others 92 tall but never anymore than that. The problem I have is that all images loaded are aligned to the top of the mc they replace and if a thumbnail is 92 wide by 20 tall than theres alot of space underneath it - i need to center (both vertically and horizontally) the loaded data and I have come up stumped.

I'm working on the Kirupa photo gallery and that works fine. Now I want to change how the thumbnails are loaded in. I would like them to be loaded in a holder (now in an emptyMC) so that I can put a mask/ border on it.
This is the thumbnail function:
Code:
function thumbnails_fn(k) {
thumbnail_mc.createEmptyMovieClip("t"+k,thumbnail_mc.getNextHighestDepth());
tlistener = new Object();

I'm trying to animate the list of thumbnails I have imported from an XML doc in my movie. In as2 I had something like:
[Code]...
So I've decided the best way to animate them in a staggered fashion is to create a "clipArray:Array" and then push in one thumbnail at a time. Then animate the clips using Tweenlite's TweenGroup. However, I don't know what would make the most sense as I'm new to the display model. Should I try to push in movie clips or holders? I'm not sure would make more sense down the line with the new format in AS3.

I have a set up whereby I have a shell AS3 swf which loads in an as2 swf to a movieclip. The two swf's don't need to communicate with each other. This works fine, and the AS2 swf contains its own code for the user to interact with it. However, I'm using a simple setInterval in the AS2 swf to fire a few animations in sequence if the user doesn't interact with it for a few seconds. This works fine when I publish the AS2 swf on its own, but won't work when its loaded into the AS3 swf.

note I have to change some file names and urls for company privacy.I am working on an online banner ad which tight size requirements. In order to stay under the file size, I want to load an external swf housed on our server into an empty movie clip on a button press. I have this working with the following code on a button:
on (release) {
loader_mc.loadMovie("location where swf file is housed");
}
I then want to unload this movie if a different button is pressed. However I am receiving the following error.
*** Security Sandbox Violation ***
Connection to file: XXXXXXXX halted - not permitted from "location where swf file is housed"
-- Remote SWFs may not access local files.
How can I unload this external swf file from my move? Again the external swf file is housed on our sever and the main swf file will be housed with the place we are advertising.

Trying to load a simple swf movie into my mc holder.When I preview the page on my desktop the external files loads. On the FTP server it doesn't. Why? I tried 2 scripts for an "onClipeEvent" on the empty mc holder but nothing workes. [code]Then I got recommended to use this script on an empty keyframe. It works but again, only offline.targetMc.loadMovie("floorplans/301.swf");

If my holder's alpha equals 0 can its child's alpha be effectively > 0 ? In my case I have holders (custom clases) with many children, some of which are holders them selves (with their own children and holders and so on).
I would like to:
-pick out a single holder from the 'tree'
-have all of the 1st level children of that are NOT holders themselves have an alpha of 1.

I am trying to load an array of web_thumbs into an array of thumb "holders" I've got the holders loading in a grid but then the way I have it, all of the web_thumbs load into each of the holders instead of one web_thumb per holder - I've tried it every which way and this is as close as I can get it without help... Can someone tell me what i need to do to have one web_thumb load into each thumb holder? This is what i have in place:
var dataLoader:URLLoader = new URLLoader();
dataLoader.load(new URLRequest("web_thumbs.xml"));
