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, 2010if 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.
Flex :: Null Cast Between Parent And Child Objects?
Mar 1, 2011I have a flex application with two objects: a parent widget (called an IBaseWidget) and a child widget (called a HelperWidget2).When the user clicks on a help link, a helper widget is loaded into the list of base widgets and then displayed for the user.However, when I try to access this child widget by casting the base widget in the collection to the child widget type,the child widget returns null and I am unable to work with the widget.The following snippet correctly returns the widget ID of the newly added widget and dispatches an event to load the widget:
var id:Number = WidgetManager.getInstance().getWidgetId("Helper");
ViewerContainer.dispatchEvent(new AppEvent(AppEvent.WIDGET_RUN, id, openQuickQueryCanvas));[code].........
The problem is that helperWidget above always returns null, meaning the cast isn't successful.
ActionScript 3.0 :: Parent.removeChild(child) Doesn't Update Parent Width / Height When Child Was Rotated
Jul 29, 2011I 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.

Jul 29, 2011I 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 :: Tab Indexing Loop Through Parent, External Child Swf, Back To Parent?
Nov 11, 2009I 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, 2010I 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, 2010Here 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?

ActionScript 3.0 :: Setting A Child To Null Perhaps?
Sep 30, 2009I've having a problem when I am removing a child. There is an area where you can choose a button to click(there are multiple buttons here). Once you click a button it loads workss_mc and you can go back from there and workss_mc is being removed then work_mc is being added again. The problem is once it is added again and you click on any of the other buttons the frame label from the previous session when it was clicked is still at that location.

Actionscript 3 - Flash Parameter Child Must Be Non-Null
Jun 8, 2011I'm having this error in which I have a Main Menu scene, an Options scene, and a game scene. I have a external file which holds all the public variables that I need between scenes. In the game, there is a picture of water in the background which is purely decorative and doesn't do anything, the only time I use it in code is when I'm moving it to the back so other platforms can be positioned on top of it by using the code:[code]This used to work before I put the options scene in, and still does, provided I don't go to the options scene. Even if I don't touch anything on the options scene, simply going there causes this line to throw a "Parameter Child must be non-null" error. I tried to trace gfxWater right beforehand, but just got null. I simply dragged the water onto the screen to create it and gave it the instance name gfxWater. I don't understand how that could be null, its still there even when this line breaks, it's just on top of everything else.
In the options menu I am not doing anything with the water, I'm only changing variables such as whether or not to play music or sound effects, stuff like that. Nothing relative to the water. The only thing that I can think of that might be causing a problem is that I used a custom font in the options scene, so I had to create the text in AS3.[code]
