ActionScript 3.0 :: Difference Between Two Objects?
Oct 7, 2010
I have two similar Objects. I want to compare them to determine if they are different data-wise (see below), and if so, display what the difference is. To complicate things, let's say the Objects are totally anonymous - I have no knowledge of their structure, contents, cannot attach listeners, etc.Comparision turned out to be easy: I'm using the classic "Serialization" approach, which comes from Java:
ActionScript Code:
public function compareObject(obj1:Object,obj2:Object):Boolean {
// serialize the objects
var buffer1:ByteArray = new ByteArray();
[code]...
If the data in the objects is in any way different, the routine returns false... classic Byte-compare. Easy, fast, very efficient.Now here's my question: is there an easy way to determine WHAT the difference is? I'm thinking along the lines of some kind of change object or XML structure that says "This field changed value, that array got this item added, this property was removed, etc".I started playing with complex looping structure and iterators until someone pointed that some object fields/properties cannot be found via iteration.
Possible Duplicate: What is Adobe Flex? Is it just Flash II?tell me in layman's term as to whats the difference between flex and flash objects. i know that programmatically there are differences and there are difference in the extension but then why do some flex programs have a .swf extension since the extension for flex is swc ?
I have to validate that 1) the end Date is not less than the start Date and 2) the difference between the two UTC Dates is not more than 12 months. To do this, I need a monthDifference function:
public static function monthDifference(start:Date, end:Date):int;
Since partial months can be confusing, this is how month differences are supposed to work:
The month difference between January 1, 2010 and January 31, 2010 is zero (0).
The month difference between January 31, 2010 and February 1, 2010 is one (1).
The month difference between January 1, 2010 and February 28, 2010 is one (1).
The month difference between January 1, 2010 and March 1, 2010 is two (2).
How can I calculate month difference in ActionScript 3.0?
my understanding is that primitive types (uint, string, Number, etc.) of a class do not need to be set to null for garbage collection.
for example, i am not required to write this dispose() method in the following class:
package { //Imports import flash.display.Shape;
[Code]....
if this is true, which i believe it is, what is the difference between objects of primitive types and objects of non primitive types concerning memory allocation?
Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?
I'm using Zend AMF to send my remote objects to Flex. I've defined a Constant class and created getASClassName() method. Then I've created Action script class in flex.
Objects are send successfully, but they are deserialized to generic Objects in Flex instead of specific ones. EDIT: On network monitor in Flex I can see that AMF value is set to com.my.project.valueobjects.Constant. Although array from event.result contains Objects.
I have an array of temporary objects created in a for loop. The objects are of type class "Tile", a class I created. However, it appears that whenever I create a lot of tiles in the for loop, the program slows down indefinitely.
While the array is whiped at a later trigger point, I am thinking that perhaps these Tile objects are not being erased from memory. They are being created on the fly in a for loop, and the array is being reset to "array = []".
Are the objects still in memory or are they cleaned up when the array is set to []?
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 have a service which returns an Array of ObjectProxy objects. I would like to cast this to a custom object (a value object) and create an ArrayCollection. How can I do this?ited:I am using Django and PyAMF for the backend. I had to write a custom SQL query and I am wrapping the resulting records in ObjectProxy and sending the whole result as an ArrayCollection.Here is my client side code:
[ArrayElementType("SessionVO")] [Bindable] private var _list:ArrayCollection;
I will try to give as much detail as I can. I am creating an CRM application using Flex(Cairngorm 2)/Java/Hibernate. The basic problem I am having is this: I have a Customer class in Java that has an ArrayList of Address classes. I have a Customer class in Flex that has an ArrayCollection of Address classes. When I make the remote object call for a Customer I get back a Customer object in Flex, but the ArrayCollecion objects have a data type of Object instead of Address. If I try to call for a List of Address classes I get the same result. If I try to call for a List of Customer classes I get a list of Customer classes in Flex. Using tomcat 6 with the following jars:
How do I align a movieclip, which width and height is user-defined, inside another object (this one is static, though). Top-left alignment is easy, x=0 and y=0, but what about center, center left, bottom left, etc? Math(.round) i suppose, but how?I want an object (static) inside the movieclip (user-defined) to stay aligned to, for instance, the top right corner, similiar to the minimize, maximize and close buttons at the top right of your browser.. The height and width data is pre-defined by the user in another file.But that does probably not make any difference...
I want to create a flash movie which firstly loads a selection of images/objects into a portion of the frame. After this is complete, the user can then drag these objects onto another area and the object will be created where the user has chosen. The user can then drag another instance of the ojects onto the area.
For example, there is a background of a lake in one area. A selection of boat pngs are loaded in an area below the lake. The user can drag these boats and place them on the lake. They can drag a boat multiple times if they wish.
I have two movie-clips, one is small-box and another is big-box .Both are rectangular shape. Small- box has an index 0, and big-box has an index 1. Their x,y are same and big-box being big in size gets hide small-box. Now the problem is the listener attached to small-box does not fire as big-box is on the top of small-box. what would be the way to get listener fired when click on small-box area??
Is this the correct, most efficient way to recycle objects when creating an array of objects?
package com { public class CreateList extends MovieClip { //this is the object I will be recycling private var newProperty:PropertyRow; //this is the array I will use to reference the objects
i am intermediate programmer.but i think that has ended 2 days before when i came across a simple while loop.which i can't figure it out how the stuff works..[code]from 1 - 9 ,that is (1,2,3,4,5,6,7,9);I want to know difference between pre and post additions in the loops.if the first program adds the increment value after each loop , then why didn't it prints the (0) value. and i also want to know that ,Why this methods does not have any difference on for loops....
I am trying to load random external SWF's using XML. I'm not having any problems loading JPG files, but the SWF's just won't load. Is there a difference between JPG's and SWF's when loading using loadMovie? Pointers to tutorials or pages in the manual would be great.
Here's a snippet of the code:
[AS] function firstImage() { if (p<(total-1)) { p=random(total);
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 was looking for the difference between the different content types in Flash CS3/CS4 - Browser/Screen Saver/Application etc - especially it's capabilities and limitations. Of interest are Standalone player and Application.
Suppose I'm building a game where your ship moves with left/right keys.I assign a speed variable which is the number of pixels the ship will move when you press one of the said keys.Currently (on the tutorial I'm following) I have:
Quote: static const speed:Number = 150.0
Can't I just replace it:
Quote: var speed:int = 150
Also, what's the difference between var a:Number and var a:int? And is there any important reason to add the .0 in 150.0?
