ActionScript 3.0 :: Create And Define A Variable In A Child From The Parent?
Oct 14, 2010
is there anyway to create and define a variable in a child from the parent? For example, if I add a child to the stage with code, and then want to be able to say
child.variable=0
to create a variable in the child and be able to edit and read the variable. I know the above code is way off but it's just to kinda get the point through.I have to define the variable this way.
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).
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:
[Code].....
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.
This is probably a fairly easy answer, but I can't figure it out. I have a dynamically added child, and I have a dynamic text box on the parent. I'm thinking that it should be possible for me to add to the text box from the child timeline, but I don't know how to target the text box.
Is it possible to pass a variable from child to parent movieclips. I can pass it from parent to child but not the other way around. I have a main movie which loads a child movie: loadMovieNum("slides.swf",1); I want to pass variable from slides.swf to the main movie. Is this possible?
I have a simple BOOK script where I have 10 pages (for example purposes). Each page has a vocabulary word on it. Currently, I simply created a vocabulary MC separately for each page and it works fine. Problem is, that leaves me with 10 Vocabulary pages and I would rather have 1 that loads info based on a var on the main page.
WORKING SCRIPT var loaderZ:URLLoader = new URLLoader(); loaderZ.dataFormat = URLLoaderDataFormat.VARIABLES; loaderZ.addEventListener(Event.COMPLETE, loading);
[Code].....
I am getting the word "depressed" from page 1 (verified by trace) Unfortuntely this does not work.
If I change the last line of code to:
VocText.htmlText = loaderZ.data = word;
Then it outputs the word DEPRESSED to the text field VocText but does not return the value from the txt file.
I am getting the following error:1119:Access of possibly undefined property through a reference with static type TenI am explicitly casting, and tried this.parent and still get the same error. What am I doing wrong.
Here is the code: package { import flash.display.*;
For instance, in the below code a parent can control a SWF child's function "alert ()". But how a SWF child can control parent's function "ReceivingChildMsg()" ?
I have a public variable set within fx:Script tags in a parent component that I'd like to access directly from a child component. How can I do this? I don't want to pass the variable to the child component (I know how to do this and am currently using this approach). Following is a simplified version of the mxml:
Note: SimpleComp is an HBox with a couple of lists. <mx:Accordion> <comp:SimpleComp/> </mx:Accordion>
type_elt is not an element name; it might be <single>, <multiple> or something else, determined at runtime. How, given this, can I detect the presence of the opt_out_flag element?
I tried this (where xml refers to the question element):
if (xml.*.opt_out_flag) { do_something(); }
but even in cases without opt_out_flag the above expression returns true. Obviously I'm missing something, but what is it?
its necessary to create a localconnection object in both the parent and child swf if bi directional comm is desired ?? so ..
[Code]...
the child is loaded and unloaded multiple times ..the 1st time .. no issues ..everytime thereafter when the child is loaded .. I get .. "ArgumentError: Error #2082: Connect failed because the object is already connected." when the child is unloaded .."ArgumentError: Error #2083: Close failed because the object is not connected."seems like the connection is persistant until the child is instantiated
I'm trying to take a variable from the parent movieclip and use it in the child movieclip inside of a dynamic text field.
The variable has a value that is taken from a php file.
I'm completely lost at the moment and know that my code is probably completely wrong.
here it is:
parent movieclip: var loader:URLLoader = new URLLoader(); loader.addEventListener(Event.COMPLETE,onLoaded); loader.load(new URLRequest("../SC/FLA_cont-btn.php"));
[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]
I got a "preloader" that creates an movieclip and loads an SWF. Now in the loaded SWF i want a close button to go back to the "preloader". The preloader isn't an actuall preloader but some sort of mainclip.Now i tried this:removeChild(MovieClip(e.currentTarget).parent.pare nt.parent)But i get error:ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display::DisplayObjectContainer/removeChild()at MethodInfo-6()
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.
trying to on mouse over set the parent of the moused over text field to the highest depth child of its parent i tried both of these: [code] private function
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.
I am trying to make a calculator where a user can select from a list of items. If a user clicks say "ITEM1", it should add the item to a "CONTAINER_MC". The problem i have is all my data is set inside an array containing names and prices like the code below.
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?
I have the need to change a variable in a child Flash file.
The setup is a parent Flash file, that has called a child Flash, and placed it in a movieClip.
I can send a variable using Javascript to the parent Flash file, but not directly to the child Flash file. Is there a way that I can access the child Flash file directly with Javascript?
Or do I need to send the variable to the parent Flash file, and then have the parent send the variable to the child Flash file? Is there a sort of dot notation that I can use with Javascript to get to the child Flash file without first accessing the parent, when the child is added to the parent using the loadClip function in flash?
