ActionScript 3.0 :: Communication From Child To Parent
Jun 30, 2010
I have a blank fla with a symbol in its library. The symbol, a MovieClip, has timeline action in it. It's about 15 frames long. I want it to tell the MainTimeLine when it's done.I must be going about it the wrong way.First, I make a variable to hold the child.I call the MovieClip from the library, a new instance of itself, declare it a child of the MainTimeLine, and add it.From within the child, I trace it's parent. I get "MainTimeLine".I create a Boolean on the mainTimeLine.When I ask it to set the Boolean, I get the error message:1119: Access of possibly undefined property currentFrame through a reference with static type flash.display DisplayObjectContainer.I've attached a zip of the fla.

I'm very new to AS3. Luckily I succeeded loading an external swf into the main swf. Now I want to add a remove btn, so when the movie is finished playing, user would be able to click the btn to unload the external swf ( both unload movie + all sound). What should I change here to communicate it to the parent movie?

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.

i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).

When Sprite2 is NOT rotated:
Code:
trace(SpriteP.width + ' ' + SpriteP.height); //100 250.
SpriteP.removeChild(Sprite2)
trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good.
When Sprite2 is rotated at 90:

And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.

[code]All clips are squared.Ok, on the PlayerPlane, there are little soldiers, which have hotkeys. The effect I'm trying to create is I want to position the GameStage so that the currently selected soldier appears in the center of the GameClicker clip.The GameStage is movable by the player (to scan other areas of the map)by holding the CTRL key, so it's easy to kinda lose track of where your players are.I have tried using localTo Global and globalToLocal techniques, but I think I'm lost on the actual math of getting the GameStage to move the correct distance so that the selected soldier is centered to the GameClicker.[code]

if I add a clip to the stage as a child and remove the parent and set the parent equal to null, does the child get collected and removed from memory? What if the child has an image loaded into it as its child?
In my application I'm loading a series of png images as overlays that can be tinted for customizing in this app. When I trace my memory, the basic app idles at 64,000 k. The exact second I load those overlay images it goes up to 205,000k. If I remove those clips and "clear" the stage I should go back down to 64,000 k if everything is removed and collected correctly, right? It's not, it's hanging at 215,000 k. Are my images being cached and that is the reason for the memory staying up? If so, how do I prevent that. Or upon removing the parent of the image how can I un-cache the image.
If a user switches between models and loads several different items then the application actually crashes the Flash environment because of too much memory usage. It also does the same to browsers.

I have a parent swf which loads many child swfs (though only one is displayed at a time). My intention was to use the loaded SWFs document class to retrieve an array of objects to be assigned a tab index, combine this with the parent's own array of objects and apply sequential tab indices to them all. But what happens is actually that the parent's objects are assigned an index, but the external swf is unaffected. In fact, the external swf retains its automatic tab indexing, when I would expect that having set a value for InteractiveObject.tabIndex, automatic tab indexing would be disabled.
I've seen similar tales elsewhere. Most posts I've read are wanting to load an external swf, give it focus and loop through those objects, then close the swf and return to looping through the parent. However I would like loop through all objects as one. including manipulating the focus manager(s), and basically fiddling with every tab-related property I know.

In a nutshell, this project is an eLearning course template. It needs to be able to load/unload individual page swf and these page swfs need to communicate back up the chain to some level for this like module / course completion. On the stage I have a pageLoader_mc linked to a PageLoader class. What I need up doing is added my LoaderObject to the display list of my pageLoader_mc MovieClip:
Code:
package {
import flash.display.MovieClip;
import flash.events.*;
[code]....
The Swf of the course loads. When you go to another page after it unloads the SWF I get an error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::AVM1Movie@37710d61 to flash.display.MovieClip.
at PageLoader/loadComplete()
The Overall question, is how can I instance that loaded SWF so I can listen to custom events? In my loaded swf I guess I can "MovieClip(stage.pageLoader_mc).CallMyFunction "

I have an issue where removechild won't infact remove a child. I think its something to do with my dropTarget.parent issues. The concept of the code is that you drag a source onto a destination. When you drop the source onto the destination you will get a text field that says "Hello" or "Goodbye". The objective i want to achive is that once i drop a source onto the destination, removechild will remove any previouse textfields added. This is proving difficult.

Here is a working script to drag drop a ball from the stage into another target mc:
ball.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
stage.addEventListener(MouseEvent.MOUSE_UP, dropIt);
function pickUp(event:MouseEvent):void{ [code]...
It works well but I'm new to AS3 and I am having difficulty amending this script to drag the ball out of a parent mc (instead of the stage) and onto another mc (the target mc). To explain: imagine a ball, a box, a tri, + more shapes all within a scrolling mc (initial parent), the user scrolls to select a shape, then drag-drops onto a target mc on the stage.The scrolling is no problem, but how would you amend the script above so that the ball can start inside a parent mc rather than on the stage itself?

Some forums suggested to simple add the child to the new parent and it would automatically be removed from the old parent. However, these were Actionscript 2.0 forums and the suggestion didn't work - it removed the child but never added it back.MovieClip(root).bmc.addChildAt(currentLetter, 0);Is it possible to take a child from one parent and add it to another in AS3?

I have a MovieClip instance which can be moved around the stage using startDrag() and stopDrag(). The instance also has some child MovieClips using addChild(). The parent moves the children when dragging, which is fine. The children have there own startDrag() and stopDrag() which should apply only to the child object, however it also moves the parent and other children. When clicking a child the MouseEvent of the child is being called but so is the parent.
public class Component extends MovieClip {
private var nodes_array:Array = new Array();
public function Component() {
x = 60;

Im using the following code to place an object inside a container:
testParent = new MovieClip();
testParent.graphics..beginFill(0x0000FF);
testParent.graphics.drawRect(50, 50, 300, 300);
[Code].....
this gives the testParent object a margin of 50 from top and left. The testChild object should have have the same margin relative to stage. But doesnt.. The child object is at 0,0 relative to stage. Whats causing this?...

I have a SWF file that I call the a parent, it imports a number of SWF(children) which I can switch through. is it possible to have a function in the parent SWF that the child SWF can launch?
The reason I need this is because each child SWF is a sort of small game, so when each game is finished I need some kind of way to let the parent SWF know that the player can continue.
