I'm trying to create a quick access to a object with a String as it's key, so I wrote:
"var map:Object = {};
map["key1"] = object1;
map["key2"] = object2;
..."
Is there any difference about the performance between long key and short key(the length of the String used as a key)? If the key contains many charactors, will it slow down when accessing that object?
It's too complicate to explain but I'll give you an example
I have an AS3 ResultEvent Object and this object has several propeties which can be accessed by this like:event.result.name or event.result.age and, I have this String variable: eventProperty:String that contains "name" or "age" How do I access to event.result. with the variable?
How can i use a string to access the object instanced as : beef : on the stage.

Was at a site the other day that used a shared oject to tell me how long I had been viewing the page. I left the page, came back and the counter restarted right where it was when I left. This is cool, but what if there are say 30 people viewing the same page at the same time? As I can't write the code "myObject = new sharedObject" to get a new instance of the shared object, how is this done? Or, when I use the "get local (remote) sharedObject" does that give me a new instance of the shared object? Or is there only ever 1 instance of a shared object?
The reason I ask is say I'm writing a multipalyer game, and I want to store user information in a shared object so it displays in everyones swf. Well If I have only 2 people playing the game, fine, that's 2 shared objects. But what if there are 100 people playing the game? Or am I looking at the shared object use all wrong in the first place? I only have a small pea sized man brain so the logic escapes me...
I just wanted to check something if anyone can clarify this:
If I create an object with
Code:
And then replace it by doing
Code:
Does the original instance get deleted or will it remain in memory? If it does, how do I remove it properly?
Im trying to create an inventory for an adventure game (escape the room esque interface).Basically I have an array inventory system - you click on an object that is listed in the array,it moves the item off the main screen and into your inventory (bottom of the screen) and resizes it. Then you can use the object as an inventory object.This is fine on frame one (where all the items are at the moment).But when you move to another frame and then come back to frame one the items are back on the screen in their original position but now non clickable(aswell as being in your inventory working how they should). If i put the items in frame two and no items in frame one I get the following message and the items become unclickable:
Code:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Inventory/makeInventoryItems()
at InventoryOne
Im guessing the errors are because the items don't exist on all frames but the code does as it is in the games properties as the class type (class Inventory), but i have no idea how to get around it.
Inventory/makeInventoryItems() is the following AS code.
Code:
function makeInventoryItems(arrayOfItems:Array) {
for(var i:int=0;i<arrayOfItems.length;i++) {
arrayOfItems[i].addEventListener(MouseEvent.CLICK, getItem);[code]............
I'm creating a CMS(Content Management System) tool so that users can change text and the changes be reflected in a text window in flash . The text that the user enters in the CMS tool will be stored in the database.
In flash I want to parse the string that I get from the database and look for URL strings that start with http "http://www.someurl.com" and parse out that substring.
For example the string could be "Please vist my site at http://www.site.com". I would want to parse out the http://www.site.com
If I find this url string I want to pre-pend the a href tag <a> and append the closing </a> tag to the string so that this link will be clickable from the textfield.
Does flash have an object that deals with Regular Expressions? I've looked at the String object in flash but not sure how to achieve this task

I am developing an application with Flex for the GUI and Restlet for the webservices. I have a strange problem. I put my XML as a property on a generic object, and send it as part of a POST request. But in the Restlet webservice, this XML is irretrievable. How do I retrieve it? I tried initialising the received Representation object to a DomRepresentation, but thats not working. If I put the received Representation object into a Form object, then getFirstValue is returning that XML as a string! I noticed that the contentType of the HTTPService was application/www-form-encoded so I set it to application/xml and its not helping either. I use restlet 2.0m6 and here is the code snippet that I use -

View 3 RepliesUsing e4x in flex:
var attr : String = "foo";
var xml : XML =
<resultSet>
<node foo="1"/>
</resultSet>;
How can I use the variable "attr" to access
xml.node.@foo
I thought I could do it with
xml.node.@[attr]
But this doesn't seem to work. How can I access this attribute by a dynamic value like this?
Both
xml.node.@[attr];
and
xml.node.attribute(attr);
work, as Constantiner suggested.
Updates:
Say I have an XMLList in this form:
var bar:XML =
<resultSet>
<node>value</node>
</resultSet>;
I want to filter the original xml above by matching "foo" attributes with the "value" from node in bar.
Essentially I want a sublist of the original xml such that
xml.node.@foo == bar.value
for each xml row in the original value
As Constantiner mentioned, I can filter the original list by the value in foo, but what if I want to filter on multiple values?
Can I do something like:
xml.node.(bar.node.contains(attribute(foo)) ? attribute(foo) : null);
Or perhaps a cleaner method instead of the null?
Suppose There is one [url]...
I want to access the id="123" from the above URL.
