I am wondering if it's better to pass an instance of a whole class to another class or just specific properties of that class. For example if I want the height property of class A in class B do I pass just the height value into class B or the whole instance of the class and use classA.height in class B?
View 3 RepliesI have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
I have a main swf that loads different swfs files, one of this swf files is the homepage with navigation items, how can I pass a reference to the loaded home.swf of the main.swf which contains the load methods?

how i can pass parameters to an instance of a class using the Object.registerClass method. It seems i can only put the name of the class but no extra parameters.
View 3 RepliesI'm having a little trouble with the properties of an instance of a specific class. Here's and example of the code I am using:
Code:
package {
import flash.display.MovieClip;
import flash.events.*;
public dynamic class Circle1 extends MovieClip {
private var _root:Object;
[Code] .....
This is in the class code for Circle1. Now here is the error that is being displayed int he Output Box when I try to run the file:
Code:
TypeError: Error #1010: A term is undefined and has no properties.
at Circle1/eFrame()
Here's the code that creates the two class instances as children on the Main Time Line:
Code:
if (spaceDown) {
var newCircle1:Circle1=new Circle1();
addChild(newCircle1);
} if (enterDown) {
var newCircle2:Circle2=new Circle2();
addChild(newCircle2);
}
EnterDown is a defined variable for the key press of Enter, and spaceDown is a defined variable for the key press of Space.
I have a small issue with instantiation of an xml loader class. I'm using a standard way of loading external data and assigning it to "myXML" variable. My class uses event.COMPLETE for loader to make sure that data is fully loaded. Everything works fine until I make an instance of this variable in to my Main() class. The trace of "myXML" gives me null. It's like it didn't assign data on time. Since the onComplete event handler should take care of any delays it is hard for me to figure this out.

For example, I have the class Bullet, with a constructor: Bullet(start:Point, target:Point)constructor
But, if this Bullet class extends the MovieClip class, how do I pass start and target into it? Right now I am using attachMovie to create instances of the class. (They behave correctly with the static properties set by the constructor, but to be useful it needs arguments.)
I have a class ErrorMessages which holds all my error messages as static constants. So I could access them like ErrorMessages.PASSWORD_INVALID or ErrorMessage.PASSWORD_TOO_SHORT. I want to know if it is possible to have separate classes that hold subset of these constants and access them like ErrorMessages.PASSWORD.INVALID or ErrorMessages.PASSWORD.TOO_SHORT, etc. This way I can more structured static structure and makes it much easier to use autocomplete. I tried few different ways and couldn't figure out if this was possible..

I'm using a library that has a function that returns an instance of some class Engine.
I'd like to tack on some interfaces to Engine, so I subclass it class InterfacedEngine extends Engine implements AwesomeInterface. but when I change the code that uses the classes from this:

to this: var interfacedEngine:InterfacedEngine = generateEngine();
It gives me a runtime error (elision mine):

What about AS3 classes am I misunderstanding?
I'm creating a little game - The player controls a character that follows the mouse. Pigs run away from the player, and the player has to get them all into a pen. To make the game a little more difficult I'm trying to add an enemy - wolves, that attempt to perform a 'hunt' method every x seconds. This method sends a reference of the wolf instance to Main (my document class) and Main then loops through the pigs on stage to see if there's any nearby. Now as far as I know this works - my problem is I'm unsure how to send the pig instance reference back to the wolf that called the hunt method, so it can then 'target' the pig, and then attempt to pounce on it.
This is my Wolf class:
Code:
package
{
import flash.display.MovieClip;
import flash.events.Event;

Quick question. I have been Googling this all morning, but it's either not there, or else written in a way that doesn't register. I am inclined to believe the latter, as this seems like it should be something completely trivial to me. I made a small Flash file using AS 3.0, and this is the first time I've really been able to stick to the OOP way of doing things and not hack together a mix of stuff from the timeline to get around not having everything work in the classes.
So I'd like to keep it that way, but one thing is eluding me: I can't call a method of an instance of another class (than the one I'm calling from) without resorting to "DocumentClass(root).instanceName.method." Intuition tells me there has to be a better way of doing this (like, without having to reference the document class every time I call another class instance's function; and CERTAINLY without having to use the word "root" - that just seems so Flash 5 to me. Does anybody have a better way of doing this that they can share?

Is there anyway where I can pass the Array values (not the array collection values) to the Bar charts or column charts using flex 3.5...

and i want to show these values on the Yaxis and months on Xaxis....
I have two Qns,
1) how can I pass this array to Bar chart or column chart.
2) how do I need to show months on Xaxis. beacuse I'm asking this regarding, I have kept a filters that even if we want to see some months or a particular months or perticalar span of months... there on Xaxis it need to change the months dynamically depending on the filters..... (for ex, on Xaxis the values should be (Jan, Apr, Jun,Oct) if i select the 3 months period filter....)
I have written a logic to collect the values of those particular months into an array, but not understading how to pass this array to Bar chart,, beacuse there I don't know what Xfield and Yfield to be given....

I need to ask your advice, I am developing a site where music is uploaded by unsigned bands.I would like the player to be developed in flash.I would want an area where you can search for music and also would like the user to be able to generate play lists when they are logged in.I was going to put the filenames into the database and use PHP to grab them and display them and then use JavaScript to pass the values into the flash player.But I think this will not work on the play list.So should I get the list of tracks using PHP and use Flash to display them?Or should I be using XML and not put the filenames in the database or even both.I have spent a bit of time Googling this and thinking about how I am going to attack this so my question to you guys is what would be the most efficient way of doing this.

[Code]...
Does one way free up more memory or enhance performance?
I've created some dynamic movieclips. When I click and hold on one of them, I'd like a different library linked MC to appear, and the new MC to be draggable.
I can make the new MC appear, and I can make it draggable. However, I'm a little lost when it comes to telling Flash to forget about the old clip, and make the new one the 'live' one.
In other words - after a click-hold, I want the new movieclip to be movable without the user having to mouse up and then click again.
How do I pass values by reference inside a for each construct in AS3? Basically, I want something equivalent to the following code in PHP:
