Any good argument as to why I shouldn't use a Dictionary over an Object every single time? I can't think of any case an Object can do the job a Dictionary can't, and it doesn't seem as the Dictionary creates that much more overhead.
View 8 RepliesI am encountering a problem in my app only when it is run in flash player 10.1.85.3. Some earlier player versions I have tried are working fine.From what I can tell it seems related to the following:

When searching for objects (not strings) in Dictionary objects using the 'in' operator, if the object is not found in the Dictionary object, it will be searched for in the delegate objects. With 10.1, the toString operator will be called on the Object if not found in the Dictionary. This can cause problems with Proxy objects who need to define the callProperty function or it will generate a RTE. ...what it means "it will be searched for in the delegate objects"?
does anyone knows the "time complexity" of Dictionary class methods ? for example, is the ""get"" is an o(1) time complexity ?
[Code]...
and another question in the same topic, how does the Dictionary "generate" an 'equal function' & 'hashcode' (assuming same implementation as in java's HashMap) from the object passed as a key? is it efficient ?
I'm often seeing others using a Dictionary object in their AS3 code that simply maps objects by String keys and wondering if there is any advantage at all of using a Dictionary over a simple Object if String keys are used. Anyone know any details on this? I would suppose that since an Object is more lightweight it should be faster and preferable over a Dictionary if used with String keys.
View 1 RepliesWhat exactly is the difference between an object and a dictionary in Actionscript?
var obj:Object = new Object();
obj.something = "something";
var dict:Dictionary = new Dictionary();
dict.something = "something";
trace(obj.something, dict.something);
The trace statement seems identical...
So I am writing a program which uses Dictionary to store objects. For example
var dictionary:Dictionary=new Dictionary();
var myObject = new myObject(var1, var2, var3);
dicionary["key"]=myObject;
where var1, var2, and var3 are simply means of assigning values to variables in myObject.can I access values or functions that are found in myObject? In myObject class I have some getters and setters. Can I use a getter to get the value of var1 for example.
dictionary["keys"].getVar1()?
I'm trying to figure out a way to clone / copy a dictionary object.
I came across some articles on cloning that offer this code.
This does not seem to work for dictionary objects. I think it only really works for basic objects.
Has anybody come across a way of cloning a dictionary before
Code:
function clone(source:Object):*
{
var myBA:ByteArray = new ByteArray();
[Code].....
Why might it be useful to store an object (i.e. a Movieclip) as a key in a dictionary? Does any one have any examples of where it's used/is useful?
View 5 RepliesIn one of the classes in my Flex application I have a dictionary, which is periodically updated from other parts of the application. It contains some sort of user preferences and I want to keep it in sync with a local shared object - the dictionary needs to be read during the class initialization and saved to the local storage when an element is changed, added or deleted.
The "Dictionary" object inherits only "Object" and does not have a change event - like the "collectionChange" in ArrayCollection. So I can't sync the dictionary just by listening for an event and manipulating the shared object in the event handler. The other possible solution would be to make the dictionary private and manipulate it using special methods in my class. Something like:
public function setValue(key:String, value:String):void
public function getValue(key:String):String
public function delValue(key:String):void
But using bindings will become a real nightmare and I will have to make changes in many other parts of the application.
My project is a visual way to represent a database of information about books. It will be represented as a collection of menus and submenus. From one menu, the user will be able to access another, from the other the third.Each item in a menu has some content, so the menus themselves are not a means to an end (to execute commands), but a goal in themselves. Viewing them, and browsing between them is the essence of the project.
The simplest way to organize a menu of items would be a dictionary object containing all its members.However, it is not really good for a complex set of menus and sub-menus which is a web of information linked between another.
how to set variable time for a single timer, like I first setup this timer:
private function timer():void{
var randomTimer:Timer=new Timer(time,0);
randomTimer.addEventListener("timer", somefunction);
[Code].....
So how can I influence the time inside the timer? Do I create a global timer, remove the listener and recall the timer function? Would this work since the timer has already been declared, I a re-declare a timer?

View 2 Replieswhether using a String as the key in a Dictionary results in slower lookups than using an Object, Class or Custom Object (an instance of developer defined Type)?
When using a String as a key, does the literal String have to be parsed, or does the Dictionary key point to the String Object?
The dictionary use strict equals(===) for key comparison, how to change the comparison, so I can use my standard for comparison, for example, I have a class named Student:
class Student{
var id:int;
var name:String;[code]....
I want Dictionary use id to compare if the two keys are equal, not use strict equal(===) to compare if the key is the same.
Requirement: Create single very large bitmap data which contain some 30 PNG images loaded and for each image it should have some text. Images and text are loaded dynamically (AS2 code. Images are stored in a remote server). The bitmap data display should show 8 images at a time and corresponding text. We can see rest content by scrolling (kinetic scroll is implemented). How can I go for it?Some questions:Is there any limit for size of bitmap data ( As per link there is restriction on the height of the bitmap we can create in AS2 (max value is 2880 which is not enough for some 30 element list If we create individual bitmap data for 30 individual PNG files, we find some jerks in scroll. How can we have smooth scrolling?
View 5 RepliesI have a problem with two functions. This is the story: the user has to press the space button on keyboard when he sees something on screen, then the "rightClick" function is called. If he presses the button when there is something else on screen that is a wrong answer (function "wrongClick" is called). The problem is that when the user presses the space button both function run at the same time.
This is the call of the wrongtClick function on frame 5
stage.addEventListener(KeyboardEvent.KEY_DOWN, wrongPress);
This is the call of the rightClick function on frame 10
stage.addEventListener(KeyboardEvent.KEY_DOWN, rightPress);
Both function are very simple:
function rightPress(event:KeyboardEvent):void {
scorenum += 1;
trace ("Right:",scorenum);
} function wrongPress(event:KeyboardEvent):void {
wrongnum += 1;
trace ("Wrong:", wrongnum);
//and plays a sound too
}
is there a simulator or a way for Adobe Device Central to read CS5 created iOS published SWF's or ipa's for testing purposes?At the moment, I make a change in Flash CS5, publish the SWF and IPA, delete the old version from my phone, drop the new IPA in, re sync and test. This is not good for the workflow. What are the options for testing and developing?
EDIT:I am on a Windows machine (Windows 7).
Given the following example SWF: Sample Notice how with the words "enthusiast" at the end of the first line and "write" at the end of the second line, that they start to type out on the first line but after a few letters they are bumped.
I understand this is the correct behavior, but is there a way for "enthusiast" to begin being typed on the second line, and "write" on the third line instead of being bumped during the typing?
Currently I am thinking of doing a search ahead mechanism, so it finds the next word in whole, then makes that the active word to print, temporarily print it, see if it increases the numlines, and if it does insert a line break and continue writing. But it seems fiddly.

I'm working on a project which allowing end users to embed a flash in their own HTML pages while we offer different ways so user could choose one that works for their circumstances, for example, most blogs doesn't welcome users to inject JavaScript on their pages, therefore SWFObject wouldn't be possible, we offered two other ways: IFrame and the oldie but goodie Object/Embed pair. Just like old Youtube embedding code:

I have a BitmapData object with an alpha channel. I'd like to know the fastet way to offset that alpha channel in ActionScript3 (FlashPlayer10).

View 2 RepliesIf I'm streaming live video and chatting in an FMS app, should each component have its own instance of NetConnection or should they share one? Was thinking perhaps the quality of the live video stream would be hurt in a sharing situation but am not sure the architecture works like that.
From a development standpoint, I'd like to make one NetConnection instance in my main application file and connect with it. Then, when successfully connected, I'd like to pass that connection into any custom components that need it.
I've been trying to do a drag and drop game, the logic of the game is that I have 4 blocks grey1_mc, .
grey4_mc, and 8 targets target1_mc,target8_mc.Now, grey1_mc can be dropped only on targetgrey1_mc and targetgrey2_mc, similarly grey2_mc on targetgrey5_mc and targetgrey6_mc grey3_mc on targetgrey1_mc and targetgrey2_mc grey4_mc on targetgrey5_mc and targetgrey6_mc
when grey1_mc or any other greyBlock hits it assigned target it should be locked onto the target and should not be clickable. Also it should play a movieclip inside of it i.e., a Green Tick Mark. if grey1_mc hits any other target it should lock on to that target play a " Red Wrong Movie" and then snap back to its original position.
similar functionality is going to be used for the rest of the grey movieclips.the code that i've written is this...
var originalX:Number;
var originalY:Number;
var greyBox:Array = [grey1_mc, grey2_mc, grey3_mc, grey4_mc];
[code]...
I'm doing a project where I have a movieClip grey1_mc and I have 2 white boxes, which are also movieClips white1_mc and white2_mc. What I want to do is to add a Drag and Drop functionality such that, grey1_mc can lock onto white1_mc if droped on white1_mc, also grey1_mc can can lock onto white2_mc, if dropped on white2_mc. And the usual snapping back to original position if placed elsewhere on the stage.
This is just for one movieClip grey1_mc. I've got 4 such movieClips
[grey1_mc, grey2_mc, grey3_mc, grey4_mc,] and 8 targets
[white1_mc, white2_mc, white3_mc, white4_mc, white5_mc, white6_mc, white7_mc, white8_mc,] ,....
So, grey1_mc can hit white1_mc or white2_mc.
grey2_mc can hit white3_mc or white4_mc.
grey3_mc can hit white1_mc or white2_mc.
grey4_mc can hit white3_mc or white4_mc.
MovieClips white5_mc to movieClip8_mc are only to show a error message in the o/p window.
