I can't work out how to create a temporary copy of a 3D point class on which I'll perform some calculations which I don't want to effect the original. In C++ it's called deep copying. How do you do it in actionscript?

I just recently been using a lot of prototype javascript stuff, and was wondering there was anything like the "bind" method, for use in AS3. It's proved quite useful to be able to look both at the event.target as well as the class object the handler function might be associated with.

View 3 RepliesI want to clone a class object. I tried following from here:

BUT this only works when the class has a default constructor and not when it has parameterized constructor:
how to clone a class object when the class has a parameterized constructor?
overriding clone() while creating custom events?I read in the Flex cookbook that we need just in case we want to redispatch this event. Does this exactly means that when we want event to be bubbled up the display hierarchy , at that time our custom cloned event should be dispatched and not the Event object.
second - whats the need of metadata tag -
[Event(name="modelEvent", type="com.abc.data.model.ModelEvent")]
public class LoginModel extends EventDispatcher
I understand we need to extend EventDispatcher in case we want to dispatch evnet from class.. but In what cases i would need to specify the MetaData TAg
Third is.. If i write -- "dynamic customEventClass extends Event".. Is there any use of Dynamic i can make?
I have a collection of movieclips, I would like to create a clone (a new instance) of a instance everytime I create a new object.
For example
var s:Star = new Star(); // star-shaped movielcip
addChild(s);
// then I want to duplicate an instance of s and add it beside s
For an example like above, it's simple enough to create a new instance with a different name and just add it to the display list. But I have a list of objects I would like to clone as a group...?
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
Is it possible to make a movie clip rotate about the center point of it using the ._rotation method?

I have a rather silly question but as3's document class always gets me confused.I have a public method on my document class. I want to call this method from another class that is instantiated from within an object in the library of the flash file (the same one on whose document class I want to call a method).

1. DocumentClass
2. GameClass
I would like to be able to call a public method of DocumentClass from GameClass. I don't know how to do that, I tried instantiating an object of DocumentClass within GameClass which simply throws me into an endless loop and after a short while application crashes.
I have a class, my document class, called SilkRoadTweeter. as I also have a class called User.as In my User class I need to call a method called nonce() I have tried this, trace(SilkRoadTweeter(root).nonce()); But I get the error, TypeError: Error #1009: Cannot access a property or method of a null object reference.

I have a class called Unit. When I use this class in a .fla file, I create it by saying:

I come to need a bit more info from my points, so I thought I'd add a previousX, previousY so that I can get a deltaX and deltaY. Now, this works fine if I make a simple self contained class. I think, however, that I'd like to extend the flash.geom.Point class to benefit from the other functions and calculations it offers.
So I extended Point and modified the x and y setters as I needed. When I compile, I get an error that these setters are not marked for override when they should be. So I override, but then I get an error that says these do not override any function.

I have been using flash since version 3 as a designer.I want to know how to make an object that I have manually placed on the stage from the library with a Class attached to it, interact with the Document Class? So I am basically dragging the item onto the stage and this item has a class attached and the Document Class with all of its SubClasses needs to know this exists.
Now I was dabbling with making geometry wars to learn AS3 Classes and it was great fun, I set up the Document Class, my enemies and Player 1 Spaceship. I worked out my different SubClasses, and everything was added to the stage by AddChild() along with all SubClasses being created through the Document Class....Every Class Object was linked to the Document Class as everything was created either by it or through SubClasses under it. So I had full control to do what I wanted. However, all I ever see are elements generated dynamically to the stage. As a designer I want to animate things here and there and then at specific times possibly gain control of this item with it's Class attached, but I want the Document to have a link to this Item.
Also can everybody please stop generating text boxes dynamically all of the time. just create a MovieClip with the form elements on it if it's a form that isnt going to change in layout at all. But this leads onto the same sort of questions, the items arent being created and added to the stage as objects so you still have to make the MovieClip Class understand the items under it exist, I would do it by the Instance Name but is this dirty these days in AS3..
In the Main Timeline I have
Code:
import FlashVar;

Now I have to pass 'this' when instantiating the class so that later I can use DocRoot to get the loaderInfo for FlashVars.Is there any way to not have to pass 'this' and have the external class point to the Main Timeline?
Is there a way to use the scaleX and scaleY property in conjunction with the Tween class to scale from the center?ActionScript Code:[code]above unfortunately only scales from top left. This is not a class I can go in and move all the content by hand (so that the registration point is in middle) as it's all dynamic. I've looked al over but none seem to make use of the Tween class.
View 8 Repliesthis might be an easy question but i have not found the answer. i want a MC to move vertically upwards and then stop. i have the code below but this tweens downwards. i tried changing the -30 value but it doesn't seem to change the starting point. import mx.transitions.Tween; import mx.transitions.easing.*; var xPosT:Tween = new Tween(kText,"_y", Bounce.easeOut, -30, 56, 3, true);}; xPosT.onMotionFinished = function() {};
