Everywhere I've looked has instructed me to download plugins and addons because they're "superior." I'm just looking for a simple fade in/fade out when a child is added/deleted (if fadein is all I can get, I'll take it.) Here is a function I'm calling...

I am just trying to get my as3 tweening skills locked down around the basics. So, for this example, I have a logo / home button fading in, this code is working for that... however, is there a way to addChild (home in this case) via the tween code, so that I do not have to add the child at alpha0 "then" fade it in?
import fl.transitions.Tween;import fl.transitions.easing.*;
var home:Logo = new Logo();addChild (home);home.x = 400;home.y = 300;home.alpha = 0;
var fadeIn:Tween = new Tween(home,"alpha",None.easeNone,0,100,200,true);

To be exact this is the error.

Now I've tried several of Adobe's own examples from this page, http:/[url]....., and they all throw this error as well.The error is triggered by the TileList instance being the argument of the addChild function.Here's my package, which works fine when I change the displayComponent is be a List.

Within the main timeline I have a menu, which is a MovieClip. This menu is comprised of about 17 "buttons", each of which point to a different section of the site. When a "button" is clicked (2 examples: menu_bag_button, menu_trashbag_button), the menu will animate, moving left, and 2 library items (bag_container and close_btn) should appear to the right, both within "framecontainer".Then, while the menu is on the left, this specific button must not repeat the menu animation, thus I did an if statement finding which frame it is on, and if it's on the left, it simply clears the framecontainer and loads the content again.
The problem is that when another link is clicked, it needs to do one of two things: if the menu is in the center with no content loaded, it needs to animate the menu to the right, and load the content/close_btn into "framecontainer"; or, if the menu is on the left, it needs to clear "framecontainer" and load the corresponding content.I've tried a lot of things but since all of these buttons are within "menu_mc", the actionscript has to point to the root, THEN to"framecontainer" and everything gets convoluted.Here is my current code. It functions fine, except for the fact that it doesn't clear content, so it continues loading the frames so that one is closed, there is still other content behind it:

In my child constructor I use MovieClip(this.parent).blablabla() to retrieve info, yea I know I can pass it through the constructor, anyways I keep getting errors anytime I try to use MovieClip(this.parent) in the constructor, it gives a refrence error saying it's null.
Why doesn't that command work, is there a way around it (other than the constructor)? Is it because it's bad design? I'm calling a function that has alot of data, so I'm just passing this to the child and using the passed this data to call the parent atm, looking for a better MovieClip(this.parent) solution.

View 2 RepliesI created a new class as DraggableObject in Flash CS5 with the following definition:
package {
import flash.display.MovieClip;
public class DraggableObject extends MovieClip{
public function DraggableObject(){
[Code].....
Before running the code, I had a simple rectangle object converted to a movie clip and exported it to actionscript with the class of 'DraggableObject'. I just had it in library (i. e. no other instance in the stage). What I wanted is to create an instant of it at run-time ( 'draggableObject' ) and have it added to the display list of the stage, throgh its method 'draggableObject.addToStage()'.
And I don't have an idea as to what 'null object' referes to here. Since I created an instance in the line "var draggableObjectraggableObject = new DraggableObject()", it cann not be null....? When I commented out the line 'stage.addChild( this );' in the class definition (line9) it works with the trace statement output.
If I need to call a specific function in the parent application from a child in a flex project, what's the best practice for this? Would it be to dispatch a custom event from the child and have a listener call that function? Or to directly call the function with FlexGlobals.topLevelApplication?
View 1 RepliesI have a package that scales a pic up when the pic is moused over. Also in the .fla that references that package, I have code that loads the pics into movie clips on the stage(using XML).
My problem is that when I mouse over the pic it goes behind the other pics that are next to it. The moused over pic needs to appear above the surrounding pics. I know this is an addChildAt / indexing issue. I'm just having trouble working it into my code.
Actually, the package code (PhotoScaler.as) has a line that is supposed to make the moused over mc go above everything else, but it doesn't work when I add a pic to the symbol

Using Child Navigation to load main time line.I am new to AS3 and have done pretty well but have been caught up this area.I have been loading swfs into a loader (imageLoader) which has been added to the stage using addChild. Then with buttons and functions I load other swfs into the same loader which replace each other. I now have an swf "testProject3a.swf" loaded into (imageLoader) which has icons for navigation and when each icon is clicked I need it to load another swf into (imageLoader) and replace it's self "testProject3a.swf" with "portalB.swf".I've tried adding removeChild code to the loaded swf but it removes the original (imageLoader) and the other buttons have nothing to load into.[code]

in my last flash website i built, i created a gallery, my way of creating pages in flash are to have a movieclip as a page, so to make it easier to switch between the paged (page switching functionality is purely done in AS3). the gallery was a problem however, i needed the pictures to appear as popups, however to add the child from inside the movieclip, any masks i use would prevent the popup from leaving the immediate area of the page. so to get around this problem i basically used: MovieClip(root).addChild()
in my opinion this was a mistake, because it created other problems. the problem was that the popups are still connected to the page, even though they are outside of it, which meant that using removeChild() to switch from the gallery, meant that any popup that were still active, 'DIDNT' dissapear, and worse than that, because the page was removed, the popups lost any AS connected to them, which meant the couldnt be removed at all.

I'm trying to call a public function that is in the document class from a child of a child...
ActionScript Code:
private function handlerClick(event:Event):void {
var sendID:String = event.currentTarget._id;

var sendPath:String = event.currentTarget._path;

this.parent.parent.navClicked(sendType, sendID, sendPath, sendIndex);

When I do this I get an error "Call to a possibly undefined method ' navClicked' "

I have container swf which includes navigation that loads child swfs. Each child swf is loaded then visibility is set to false. Once a child ( an image gallery actually) is loaded it is possible to jump from image to image. What Id would like to be able to do is call a "clean up" function that returns the child to its initial state when anothor nav link ( a different gallery) in the parent is clicked. But I do not know how the syntax is supposed to be written or if its even possible.
Ideally it would look something like this in the parent container swf:
ActionScript Code:
function swapSectionIdentity(e:MouseEvent):void {
setChildIndex(background_home, 0);
getChildByName("identity_mc").visible = true;
[Code]...
the behavior I am attempting to avoid is when a child swf is loaded ( an image gallery) and then the child is invoked to display a particular image in it, afterwhich a main navigation link is clicked the current gallery is set to visible = false and a new gallery is set to visible = true. But when you return to the previous gallery the last image viewed is still showing. I want to be able to reutrn to galleries inital state as it is hidden. make sense?
I have a DisplayObject, called myView nested in a DisplayObjectContainer called myContainer. myView is the only child of myContainer.I add a REMOVED_FROM_STAGE EventListener to myView, and call myContainer.removeChild(myView). The onRemovedFromStage Event fires for myView when it's removed from the stage, HOWEVER, myContainer still has a reference to it as a child on its display list! myContainer numChildren is still 1, and that child is still registered as myView!!! what circumstances this could be happening? I realize that there may be a reference to it somewhere causing this strangeness, but if the REMOVED_FROM_STAGE event has fired, shouldn't it follow that myView has been removed from myContainer?
