ActionScript 3 :: How To Find All Objects Of Same Type On Stage
Mar 17, 2011
I'm trying to iterate through all the objects in the stage and I'm not sure how to do it. It's kind of improvised through my previous experience with C# and javascript. First I need the correct list/array with all the stages children. I need to check their type. I have a special custom class which extends Sprite with some additional properties only.
Someone proficient in actionscript 3.0 who can show the proper way to do?
for(var obj:DisplayObject in DisplayObjectContainer) {
if(typeof obj == "Pic") {

I'm studying the code for a vertical shooter game that is given in the book "ActionScript Design Patterns 3.0." The author is explaining the factory pattern and so covers just that aspect of the code -- doesn't cover hit testing. I would like to figure out how to do hit testing for this example because it's similar to something I am planning.
The code for the game consists of 12 classes, abstract and concrete creator classes, abstract and concrete product classes and a Main class. These classes instantiate the ship and weapon objects at various points in their execution. I made a separate Collision class and I'm trying to find all the objects on the stage using this Collision class so I can hit test them with each other. Here's my code:
Code:
package {
import flash.display.*;
import flash.events.*;
[Code]....
Is there a way to fix this code so I can access objects on the stage? Am I missing a cast somewhere? Or do I need a different approach to find objects on the stage in a multiclass game?

What I have is a game with a Level object, inside the Level is a Player object, and they don't have instance names given, what I'm trying to figure out is how to do is make it so that the player can change the x or y properties of the Level object.
To be more precise, I'm making it so that when the player moves in a certain direction, he either moves accross the stage, or he starts moving the Level object around the stage, it'd be in an Event kind of function, now I can easily make the Player move, but I don't know how to make the Level object move which the player is inside of.

I'm having an issue with Movieclips inside my Swf resizing to the wrong dimensions. I'm currently tracing the width of the offending clip every half second, and I can see the value change to an incorrect size at some interval in the logged output. I really want to see what code is changing the width. My plan was to extend Movieclip, override the set width property, and dump a stack trace when the value set is too low. This isn't so simple however. Flash is complaining about undefined reference to UI components that are on the Movieclip fla. Is there a simple way to find out when/why this value changes? I cannot use a debugger.
edit: The reason I cannot just extend MovieClip is because I am getting my Movieclip object from Event.currentTarget.content after using a Loader. I cannot point my Test (extends MovieClip) object at this return value because it is illegal to do so.I have an app with lots of different windows. They all open to a size of around 750x570. One of these windows contains a FusionChart. when I load this, according to my trace, the background Swf I am using changes to a dimension of about 2712x1930. This doesn't make sense to me because it looks the same size as before and at those dimensions it wouldn't even come close to fitting on my screen.If I then close the window and open another, the new window is tiny, but says it has the same dimensions as the original windows (750x570).
It is almost as if the window is scaling to the huge 2712x1930 without showing a change in size, and then showing the next window (750x570) as a size relative to what the huge window would look like. If that makes sense...

I have a WCF Service running SOAP and allowing Flex / Flash to connect to it using basicHttpBinding by using the 'Data' 'Import Web Service' option. Unfortunately when I consume and invoke this service within Flex it throws the following error...
Error: Cannot find definition for type
'http://schemas.datacontract.org/2004/07/System.Drawing::Size' at
mx.rpc.xml::XMLDecoder/decodeType()
...when using the following code...
// This will return an array of presentations
var service:PresentationAuthoring = new PresentationAuthoring();
var token:AsyncToken = service.getAllPresentationByClientId(
[code]. ..
This method returns an array of Presentation objects that are retreived by the service. At the moment there are no DataContracts and I'm allowing the POCO Presentation object to be serialised and punted out by the service that works fine. However, this class has a readonly property of the type System.Drawing.Size that derived from appropriate height and width properties. Looking through the generated code, it doesn't register a 'Size' class in the base import schema although it still seems to create a Size class.
An alternative has been to stop the derived property from being serialised using the [XmlIgnore] but that has not worked. I need a way of allowing my Flex application to communicate with my WCF service but it seems to choke on the System.Drawing.Size type and while I could change this, there are other framework types such as Point, Rectangle, etc, etc. that are utilised within the project.

I need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites). I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g. Suppose that I have a collection of Sprites (a pool, in fact). Each sprite will be added to the stage and perform some action. After that, it will die. I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage. This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System. A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...
Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc... But, this is JUST ONE scenario...
At the moment I'm trying to use a Object Pool with a Linked List... Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.

I have drawn colored rods which I have placed in the library and have put one of each on the stage with instance names likeblueRod_mc, etc.I place them around with time-line code like
blueRod_mc.x = 300.0;I have now created an Actionscript class called Problem.I build a new object from Problem which I have called Riddle.But when I put blueRod_mc.x = 300.0 in a method (of Problem),I get the message that blueRod is not accessible.So I triedstage.blueRod_mc.x = 300.0;That did not work either.

I'm writing a web based flash app that's written entirely in AS3. I have objects on the screen as part of a GUI. I would like the user to be able to resize the window, or make it full screen. I would like everything to auto-scale with the resize, but also remain in the same relative position on the stage.

I have built a site in AS2 and would like to know the position of a ball so that I can move a sign to it always.The whole website is in AS2, but I think I have written an incomplete code below for AS3. I need it for AS2 because the whole site is in AS2. The get position of ball is wrong, but I just wanted to throw in some ideas eg.
Code:
// get position of ball
ball_mc.addEventListener(<what goes here?>, ball_pos);
function signMove(Event:MouseEvent):void{[code]..........

I have a small issue in ActionScript 2.0. I want to know the stage width and height for external SWF file. I used the following code:
var loader:MovieClip = _root.createEmptyMovieClip('loader', 1);var obj:Object = new Object();var mcl:MovieClipLoader = new MovieClipLoader();mcl.loadClip("external.swf",loader);mcl.addListener(obj);
obj.onLoadInit = function(mc){ trace(mc._width); trace(mc._height);};
It's showing the whole animation's width and height but I want only stage width & height?

I just started coding classes and I am having some pretty good success thus far coding individual objects. BUT I realized that I don't know how to find coordinates of another object that is on the stage!Say I am coding in the class "Zombieguy".With the other movieclips linkage "Armyguy" I try toracetrace(Armyguy.y);ORtrace(Armyguy.Y);Both come up with "access of possibly undefined property y through reference with static type Class".I'm sure this is probably pretty simple, but can someone inform me of how to do this small step that is holding me back?

I'll give a complete explanation of what I'm trying to do. I have a video player as a separate SWF. In this video player I have a VideoContainer class extending Sprite, which contains the video and a control bar with specific video buttons.
This SWF is loaded in another main SWF, which has a menu that is on top of everything else. When I click "Fullscreen" in the video SWF, everything goes smoothly, except the menu remains on top of the VideoContainer object.
I need a way to change the display order of the loaded SWF, to put it on top of everything else on Fullscreen and change it back when Fullscreen goes off. All this needs to be made inside the video player. Also, the configuration of the children can change (the video player can be loaded in different places in the main SWF), so I can't use a certain unchanging path.

All my custom classes that extend MovieClip simply trace as "MovieClip" when using stage.getChildIndex(i); I'm trying to search the stage to see what objects have been placed and then add them to the correct array. E.g. if I place 5 "Enemies" on the screen, I want to then add them to an array by searching the stage for the "Enemies" class, without naming each one and adding it manually in the code.
Edit:
Code:
for(var i:int = 0; i < stage.numChildren-1; i++)
{
trace(getQualifiedClassName(stage.getChildAt(i)));

I have problems adding different movieclips to stage with the new MovieClip() command,
See EX.1>>
Here is what I have come up with:
var shape:Array = [new Shape1(), new Shape2(), new Shape3(), new Shape4()];
for(var i:int=0; i<shape.length; i++)
{[code]....
What if I need to add more than 4? It seems a bit troublesome to write the full numbers of movieclips in the array.
var shape:Array = [new Shape1(), new Shape2(), new Shape3(), new Shape4()], new Shape1(), new Shape2(), new Shape3(), new Shape4() .......];
On another note, I have 4 menu item with different width, how can I space them out nicely along x-axis one after another dynamically?
