Flex :: Animation - Get The Element To Move And Fade

Flex :: Actionscript 3 - Detect The Child Element Of A Variable Parent In E4X?

Jul 20, 2009

I have XML that looks like this:

<question>
<type_elt>
<opt_out_flag />
</type_elt>
</question>

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?

ActionScript 3.0 :: Add XML Element For Each Child On Stage?

Mar 2, 2012

I am writing a program where the user can, in the simplest terms, drag and drop things on to the stage. I need the user to be able to save what they have done and when they come back choose to reload their previous project. My plan was to write all the information(object class, x and y values etc) to an xml file and when the user chooses to load a particular project, rebuild the stage with all objects in their correct locations. My problem is, how do you add an xml element with all of its attributes and child elements dynamically for each object added to the stage?I'm relatively new to XML, but I figured this would work:

ActionScript Code:
var test:XML = <test/>;
test.title = "Test XML";
for (var i=0; i<platform.numChildren; i++) {

[code]....

in a for loop as well. But, these give me a warning that says "adding an element with more than one item is not supported" or something like that.

Actionscript 3 :: Propagate Custom Event To Parent Swf From Element Inside Child Swf

Jul 19, 2011

I have two swf file, A.swf and B.swf, each with its Document Class: B.swf is loaded in a MovieClip of A.swf. When loaded, B.swf creates an instance of CSDragger (it is a library object with its class extending MovieClip) and sets an ID property of this instance to a certain value. When this dragger is dropped by the user upon a MovieClip it sends a custom event containing the value of ID too. The custom event regularly reaches B.swf but never reaches A.swf. Aside from refactoring the CSDragger class (eg moving its handleDrop method in the B.swf document class), is there any way for the event to reach A.swf? I know I can intercept it and dispatch another event, but I was looking for a different solution (if any).[code]

Flash Layers Move To Right When Child Object Is Resized

Jun 10, 2009

I am having a problem with a flash piece that I created. I don't understand why it is doing what it is doing. I am new to flash but I have been developing software and database applications for over 10 years.I am trying to make a horizontal scroller piece that reads in data from an xml document. So basically the XML has properties of image, title, and link, I then load the images and titles into an object spaced out properly and link the image to open a new window when the image is clicked. I have 4 layers:

1. Actions
2. Buttons
3. Layer1
4. Scroller

The buttons layer has 2 buttons on it, one left aligned and one right aligned. When you mouse over the buttons, the images in the scroller move the direction the button image is pointing. The Scroller Layer has an object of type scroller (which i made) and that scroller instance name is scrollerbar.In actionscript I use a sprite object to load the image and then use scrollerbar.addChild(photo) to add the sprite into the scrollerbar. Then I set it's width, height, x and y to be in the correct position.Now when this first runs, it works displays 6 images and titles and they are linked, and has a button on the left and right. When I mouseover either of the buttons, everything gets moved to the right, the buttons, the scroller, and all the images inside the scroller. So the left button is no longer against the left side, and you can hardly see the right button because it almost gets pushed outside the viewable area.Can anyone explain why everything is getting pushed over like that? It only happens the first time you mouse over a button, subsequent mouseovers of either button do not cause this to happen again.[code]

Flash :: Accessing An Element Of An Array Of A Dynamic Class?

Jan 23, 2012

I have a dynamic class, which has an array declared normally, before runtime.Usually, you can dynamically access a variable, whether it has been declared or not with

myClass["variable"] = 4;

however, trying to do this with an array, like so

myClass["array[0]"] = 4;

does not store 4 into the first element of array, and instead stores it into the variable "array[0]". For instance, after executing the previous code,

trace(myClass.array[0]);

traces undefined, where as

trace(myClass["array[0]"]);

traces 4.

Is there anyway I can access the elements of the array dynamically?

ActionScript 3.0 :: Move Child Movie Clip From One Parent Object To Another?

Dec 26, 2011

I'm having a hard time working out the most appropriate way to move a child movieclip between parent objects.
 
I'm creating a board-game type game wherein I've dynamically created an array of 'Square' movieclips, with no visual elements, which are arranged in a 10x10 rectangle on the stage. I then dynamically add the appropriate types of piece movieclips to the various squares with the addChild() method. In general, a square should only have one child piece at a time.
 
All of this works well for setting up the play area, but now I'm having an issue with moving a piece from one square to another. I want to have the user click a square with a piece on it, then click the destination square to move the piece. I have the logic for determining where a user can move any given piece to, but I don't know how to actually move the piece.
 
The pieces are all different class objects that extend both a base class I call Piece as well as the MovieClip class. The main issue is that when dynamically adding the various pieces to the squares, I don't provide them a unique name to access them later. I don't bother with unique names because I have no way of knowing which piece instance will be in a given square, so using getChildByName(name:String) isn't very useful.
  
So I can think of two routes that I can take: Making a getter/setter for the Square class that manages a private Piece property (as well as the adding and removing of the child piece to/from the parent square), or using getChildAt(index:int) to try to access the child piece.
 
I want to go with the first route as it seems to be the most maintainable to me. My problem is that I can't work out how to manage empty squares in this scenario. My instinct is to null to private _piece property of one square once I've moved the child piece instance to another square... but I'm fairly certain that the private property is a reference type, and nulling it out will null the actual piece object even after it's changed parents.

IDE :: Multiple Masks For Dynamic Element Causing Null Object Reference?

Sep 27, 2009

I have a bunch of objects that each contain a color swatch movie clip. The color swatch contains a bunch of frames, each a different colored rectangle.The objects that contain the swatch clips also have a mask layer that defines what portion of the color swatch is revealed.

When I have one frame in that mask, everything works correctly. I can change the swatches with no problem.However, I need to create different frame for the mask. Once I create a second frame with a different mask, I get a Null Object Reference and everything breaks.

I tried creating shape tweens between the frames, making each mask into its own movie clip, and putting each new mask on a different layer - but none of that works.

ActionScript 3.0 :: Element Is ITooltippable Vs Element['tooltip']

At the moment, I'm ensuring that any elements in my application which wants to take advantage of showing tooltips implement the ITooltippable interface, and expose a public getter, get tooltip().

What I'd like to do is to add them at the top.The items in the list have a unique ID so some kind of sorting mechanism would probably do the trick as the new items have a greater ID than the old ones.What I'd like to avoid is some complex method behind this as I'm working on a mobile platform and the list can get quite big so I need this to be as efficient as possible.The list's data provider is an ArrayList that gets updated using binding.
