ActionScript 3.0 :: Creating Stackable MovieClips - Parent / Child Relationship?

Aug 17, 2009

I am creating a pile of stackable movieclips. The dragging function is not a prob but I have a problem with the parent/child relationship in the "bringtotop" function.

Code:
package {
import flash.display.MovieClip;
import flash.display.Graphics;
import flash.events.Event;
import flash.events.MouseEvent;
public class Colorbox extends MovieClip {
[Code] .....

The error generated is :
RangeError: Error #2006: The supplied index is out of bounds.
at flash.display:isplayObjectContainer/setChildIndex()
at Colorbox/bringtotop()

but i don't understand what it means...

ActionScript 3.0 :: Comunicating Between Loaded Child Movieclips And Parent Holder Movieclips?

Aug 6, 2010

I m trying to make sense of how to load a swf into a parent MovieClip and allow them to communicate.I ve attached two zip files � one which works fine and the other doesn�t. Unfortunately (for me), the one which doesn�t work is closer to my current project.I need to load movieclips into the parent movieclip. The parent movieclip has controls which rely on values parsed from the child movieclip.In the parent movieclips I wait until the loading is complete and so the values should be passed. However, the values aren�t passed unless I use a button (or timer), to pass the values (see the working exampes).The code which doesn�t work is:

Parent movieclip:

ActionScript Code:

ActionScript 3.0 :: Parent.removeChild(child) Doesn't Update Parent Width / Height When Child Was Rotated

Jul 29, 2011

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.

ActionScript 3.0 :: Parent.removeChild(child) Doesn't Update Parent Width/height When Child Was Rotated

Jul 29, 2011

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.

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.

ActionScript 3.0 :: Positioning Parent MC In Order To Center Child MC On Parent's Parent MC

Feb 5, 2010

[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]

ActionScript 3.0 :: Add A Clip To The Stage As A Child And Remove The Parent And Set The Parent Equal To Null?

Sep 11, 2010

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.

ActionScript 3.0 :: Tab Indexing Loop Through Parent, External Child Swf, Back To Parent?

Nov 11, 2009

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.

ActionScript 3.0 :: DropTarget Parent Child - Removechild Won't Remove A Child

Aug 21, 2010

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.

Flash - Drag Child Mc Out Of Parent Mc And Add To New Parent Mc?

Oct 6, 2010

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?

AS3 :: Child Moves Parent Using StartDrag?

Nov 8, 2009

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;

testParent.graphics..beginFill(0x0000FF);
testParent.graphics.drawRect(50, 50, 300, 300);

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 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.
