How do I get a list of all the children (Sprites) on the stage of my Document Class OR how can I get a list (length) of all the children (Sprites) of a parent (Sprite)?
View 1 Repliesi 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).
View 5 RepliesI'm currently making a platform game and when the player shoots i want to add the bullets to the stage. The players gun class is in charge of adding bullets. The "players gun" is a child of "players gun holder" which is a child of "player" which is a child of the stage. is there a better or more dynamic way for the "players gun" to add bullets to the stage rather than using parent.parent.parent.addChild (bullet);
View 2 Repliesif 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.
Having some strange problem getting a width from objects placed on stage using addChild. I am under the assumption that when I add some children to a specific parent, the parents width will increase and I can use that number to immediately act on the parent. The width is 100 when traced no matter when or where I add the children. I can change it statically but the is a desktop app which depends on screen size.[code]
View 1 RepliesI have multiple children movieclips containing png images inside of a parent movieclip. The parent movieclip has a slow looping animation. The children don't stay in sync with one another during the animation. It becomes obvious to see because there is a background child clip with other child clips on top of it. It appears to only happen with movieclips containing a bitmap image. Does anyone have an easy fix or work around for this?
View 5 RepliesI have 2 movieClips loading images using XML files.
I need to set the position on this movieclips from the parent depending on their width.
The problem is that the parent have to wait that both children have loaded the images before to proceed.
I have a set of movieclips that are added as children to a parent mc. I want to scale the parent mc up but keep one of the mc's in the same place on the stage. I think the easiest way to do that is to scale the mc up, calculate how far the child mc moves and move the parent an equal amount in th opposite direction. Everything works but I can't for the life of me wrap my head around the math required to calculate the distance to move the parent mc. Has anyone else tried this? Is there an easier way that I don't know about?
View 2 RepliesI'm making a rather large flash project and so I'm concerned about memory usage. At the end of each section of the application I remove the overarching parent element that holds the content. Although this remove the parent, does this also free up the memory for each of the children contained within this, or should I run an iteration to remove those prior to removing the parent?
I'll give a little more explanation in-case I'm not expressing what I want:
addChild(movie1);
movie1.addChild(movie2);
movie1.addChild(movie3);
By using this code:
removeChild(movie1);
Does it remove movie2 and movie3 from memory or are they still stored, just unlinked?
I have setup a "LayoutPage" custom class (based on MovieClip) and I am attemptimg to create a "selected" behaviour.When I assign my "addEventListener(MouseEvent.CLICK,toggleSelection)" from within my custom class, everything works as expected, clicking any object of that class does display the correct behaviour.
Now, I would like to extend the functionality by adding keyboard modifyer to either extend the selection or replace it.For this, I thought of moving the "addEventListener" out of the class and put it inside the parent instead (my "PageLayout" class where all the "LayoutPage" live). But by doing so, the click event no longer register on the "LayoutPage" class but rather on its individual children (Page icon, Page number text field, Page Highlight shape, etc.)

View 3 RepliesI'm doing an AS2 project with a parent.swf that loads many child_##.swf's. they each use identical buttons and other library assets.tried using Shared Library concept two different ways:
1 - created library.swf and used assets from it for child swf's ... no problem when child is played by itself, but when parent loads the child's, shared assets do not work,
2- established parent.swf as the 'library', and followed the common steps of Shared Library setup, but shared assets did not work. of course, using class files works, but still I need a central place for the graphics ( I'm avoiding having my classes create graphics via draw methods ).

View 2 RepliesI have a rectangular movieClip named 'container'. In this movieclip, a function generates some number of squares.My problem is that; for example, if I generate 12x12 squares with each width/height of 40; it resizes the container to width/height of 480. If I set the width and the height of the container movieClip to a lower value; then the squares become smaller.I have been struggling for some time on this problem. I tried setting the ScaleMode of container and squares to various values but it did not work.How can I overcome this illogical (for me at least) problem? How can I prevent children from resizing their parent OR how can i prevent parent downsizing the children?

View 1 RepliesI have a game set up like so:
DOCUMENT CLASS -->
MASTER LEVEL -->
LEVEL OBJECTS
The MASTER LEVEL is a child of the DOCUMENT CLASS and the LEVEL OBJECTS are a child of the MASTER LEVEL
The MASTER LEVEL is just a border which also shows the time that has passed. The LEVEL OBJECT are stuff like the player and the finish.
The problem is that I can make the player and finish swap depths using setChildIndex but I don't know how to bring the master level in front of its children? Is this even possible or will I have to make a level container that is the parent of the LEVEL OBJECTS and also the MASTER LEVEL. So that the MASTER LEVEL, the finish and the player are all siblings (sort of).
So I am trying to bring a movieClip in front of its movieClip children.
I'm facing a problem with drag & drag actions on children mc. The parent sometimes moves too.How can I disable any reaction of the parent, without affecting children?
View 1 RepliesI have a Document class called Main.
As a child of Main, I have an instance of a class called NavMenu.
As children of NavMenu, I have multiple instances of a NavLink class: navLink01, navLink02, navLink03, etc.
Back up in the Main class, there is a function called navigateTo, which accepts sectionID variable as an argument.
My question is, what is the best practice to get the navLinks to call the navigateTo function on Main? I've been told that in the spirit of encapsulation, it is not best to pass a reference to Main down to the navLinks, and call the function from there.
But rather, it is desirable to use the event listener/dispatcher method, where the navLinks are dispatchers, while the Main class listens for the navLinks to broadcast their sectionIDs.
While this makes sense, however, don't you still have to pass a reference of the listener on the Main class down through the hierarchy, so that the navLinks are registered as dispatchers? Doesn't that defeat the purpose of encapsulation?
Is there an easy way to make a parent container (eg Group) resize when it's children resize?
Below is a little example app. When I put the 200x200 'food' in the 'stomach' the stomach & it's containing 100x100 'body' should resize to contain the food.

I'm trying to simulate some fade in/out effects in Action Script 3 programmatically, using Timer class and controlling alpha property of the specified DisplayObject in time. In general it works and looks great. As I was expecting. But after I add some more child DisplayObjects to the parent Sprite it starts to behave weirdly. Children seem to not fade at the same rate as parent object and it visually noticeable, and ugly. There seems to be a short lag after parent already started to fade out and before children actually follow. Are there any additional measures I should take to avoid that? I do alpha manipulation only on parent object. I thought that'd be logical...
View 2 RepliesI have code like the following:
<s:VGroup gap="10" id="group" height="100%">
<s:Label text="This is page 2" />
<s:Button content="Resize Canvas" click="resize(event);"/>
<mx:Canvas id="photoCanvas" color="#567898" backgroundColor="#125567">
</mx:Canvas>
</s:VGroup>
I don't understand why the following does not work:
Pushing the Button resizes the photoCanvas's height (gets taller or smaller). Since the photoCanvas control is a child element of the VGroup shouldn't the container update itself to the new height? The Vgroup has ALWAYS the same height, no matter what the (total) height of the children is! I would like the VGroup to adjust itself and get a height value equal to the sum of its children heights. Is this not possible??
im trying to get the grandchildren from all the children nodes and assign them to each parent in an array.
how many there are or the maybe none should be assigned to an array for that main parent. So basically i can list all the grandchildren data when i load the parent Nodes.

If I change some value for a parent sprite, the same value will affect all of its children. So if I set alpha or width on the parent, the child will automaticly get the same value.
View 4 RepliesRed: Shape inside parent movieclip,
Yellow: Children inside parent movieclip
I'd like to animate the yellow dots, but make sure that they never gets out of the red shape's boundary.
I have placed 3 movieclips named mcParent, mcChild1, mcChild2 and 1 textbox in flash. child are childrens of parent movie clip. child1 and child2 both are of sizes 300 whereas parent movieclip is 600px, textbox is placed inside child2 movie clip .
I have made the flash to auto resize according to the screen area. Everything works well, but after resize it resizes parent and all childrens and textbox which is correct. The problem is with the correct placement of textbox on mcChild2. I have seen that after resize, mcParent width and scalex both changes but the child clips doesn't changed its sizes even they are stretched but there sizes are not updated due to which I am unable to get the exact location of where to place the textbox.
