ActionScript 3.0 :: Separate The Code Into Classes?
Dec 8, 2010
Im currently trying to make an as3 fantasy football application for my uni course, but am finding it hard to seperate the code I have written into classes (which I have no been told is the only accepted method for the marking scheme). So far I have an external XML file containing player names load into a datagrid component, there is then an event listener on the table which loads the player images into their correct positions on a pitch when clicked. I need to write more functionality for it including saving to XML and error handling but feel I need to sort out the classes situation before I continue and it is in for this week.
Code:
import fl.controls.dataGridClasses.DataGridColumn;
import fl.data.DataProvider;
import fl.controls.ScrollPolicy;[code]..............

Is there a way to make code on the timeline and code in a separate AS file communicate with each other?I have two buttons, a yes button and a no button.I have a confirm box which is a movie clip. In the movie clip I have the two buttons on it and code so that every time one of the buttons is clicked it runs a function.I have the rest of my code for the movie (so the code to make the confirm box appear) on a separate AS file.Is there a way I can define the functions on the movie clip and run the functions with the separate AS file?

In flash cs5 can you have AS3 classes in separate files like in flashbuilder. I just want to make games with just actionscript and no flex/authorscript

I'm still struggling with the complete concept of custom event handling within AS3. I know I am close to a complete understanding it's just not falling into place yet.[code]...

I'm laying out my code differently for my latest project. I am making a game, and I am keeping the Flash API stuff in a seperate class from the game logic.It's an aproach I've never tried before, and it's made me realize just how little I understand good OOP design.
what I'm trying to acomplish is this:
the Game class contains the step by step program flow of the game. it makes calls to a GameUtils class and DrawEngine class, these other classes have the Flash API stuff in themSo what is the best way to get the game class to control the other 2?
currently I have my program flow like this:
1. display splash image
2. add 'play' button
3. recieve click from button -->
[code]....
a more specific issue comes up at step 3: ..how do I have the game class progress without using a listener?I'm thinking of creating a method of the Game class that simply increments a step counter of a switch/case statement and keeping each step of my program flow in each case.

I'm looking for some help with the following script:
Main Class:
Code:
package {
// Flash Classes
import flash.display.MovieClip;
import flash.events.Event;
[code]....
Now, I'd like to move the blue color coded script to the separate package. When I do that, I've got many reference errors. how the code should look like, when it's in separate package, with all the references to variables that work? And how to call this function from Main class?

I've just been following the Basics of Papervision3D tut, which is very good by the way, the only one I've ever managed to get working.And I'd like to write the code as a separate as file, but I'm having a bit of trouble.In the class definition, what should it extend?[code]I tried everything I can think of and looked at other tuts to see what they've done but nothing works.

I made a button a stage, and I want the button to take the user to a separate scene that I have named "Biography page" when it is clicked. The thing is, I want all my actions on one specific layer. So I made an instance name for my button, "aboutme". The thing is... I have no idea how to write the code.

I have an xml gallery sort of that works fine when I have the code not as a class, in first frame in Flash. So I decided I wanted to port it into a class and the problem I get is at:
thumb = new Thumbnail(xmlList[i].image);
It expects 0 arguments. How come that line of code works in first frame in flash but not as a class? There is a movieclip in the library called thumb with linkage of Thumbnail.
Below if the code when used in first frame:
PHP Code:
var urlRequest:URLRequest = new URLRequest("pics.xml");
var urlLoader:URLLoader = new URLLoader();
var xml:XML;
var xmlList:XMLList;
urlLoader.load(urlRequest);

I wanted to have this Zombie Penguin enemy use a walk sound (it would be odd if he moved and was silent) but because it is initializing the whole world, simply coding the sound into his animation state won't work because it will play the sound for every existing Zombie Penguin in the world, not just the one on the screen.
Now I've tried to get around this problem by using a SoundManager class [URL] to load and play/pause the sound when necessary. I've got this working by placing a movieclip above the world and hittesting everything and when it finds a Zombie Penguin activates the SFX. If it finds the enemy and you leave the room or kill the enemy (basically any way it is removed from the screen) it will pause the sound (not stop) and then unpause if you go back/find another instance of that enemy.
The problem is, though, that if I STUN the enemy (not kill it) it plays it's dizzy animation (which consists of hit sitting down with stars spinning around it's head) the walking SFX continues to play as the enemy is still on the screen.Now in the Zombie Penguins .as file it has a boolean that for being stunned or not (bStunned), and a function (public function getZPStun():Boolean -- returns bStunned). this bStunned boolean is set to a default of false.I figure that I just have to reference that somewhere in the following code, but I'm not sure where. The Zombie Penguin's .as is ZPEnemy, so I'm calling it like so:
ZPEnemy.getInstance().getZPStun()
I've tried calling it as part of an if statement a in a number of placesin hopes that calling it will relate the current state of the bStunned boolean, but I can't seem to get it to work.
Code:
var bNotPenguin = true;
for(var i = 0; i<this.numChildren; i++) //** Sound Manager Coding (May 15)
{

I'm aware that ActionScript 3.0 is designed from the ground up to be a largely object-oriented language and using it means less or even no timeline code in Flash documents.I'm quite experienced with OOP and am comfortable writing classes. However, since I mostly use Flash for animations, I hardly ever need to write ActionScript code other than for preloaders, subtitles, quality controls, website links and so on. In fact, I still set my Flash movies to use AS2 to this day because I'm used to gotoAndPlay()/gotoAndStop(), AS2 preloaders, subtitles, quality controls and even getURL(). Of course, I really want to move on now that practically everyone's on Flash Player 9 or 10 and now that I've dabbled with other OO languages like Java, C# and Objective-C too.
I'm a complete newcomer to AS3 and am not very learned with AS2 either. Considering my current use of ActionScript, are there any cases where it's still OK to use very simple AS3 code in the timeline instead of moving code to a class, especially since moving to a class might mean unnecessarily increasing the number of LOC from 4 to 40?

I have created the following code that pulls data from an external xml file into a datagrid. I have been trying to figure out how to get it to function using classes and/or packages. I'd like to separate the functionality into separate classes for each of the following:1) A class for loading the XML file(s) (there will likely be more datagrids and more xml files)2) A class for "drawing" the datagrid based on the xml.... others you can think of?
Code:
/////////////////////////////// BEGIN xml_to_datagrid.fla ///////////////////////////////////////

I recently discovered the incredible functionality of getDefinitionByName(), I'm attempting to load in pages for an interactive book.Each page has its own functions, listeners, nested animations, and timers.When loading in these pages, no stop()s are working within the nested clips, and any interactivty has been lost.It's just a mess of a bunch of animations running over and over.[code]
In addition to having the MovieClips not running code, I am running into serious garbage collection issues.I can unload the pages from display, but all sounds continue playing.Does anyone have an idea of why these loaded MovieClips are not running code, and why they will not unload properly with the destroy() method?

Is there a way to hide various classes from appearing in code hints while using a compiled SWC?We are trying to create a SWC that can hide classes unnecessary/hidden to third party developers. There is only one class they need to reach, however that class reaches out to so many others. We tried namespaces on our classes but that doesnt work. It only works on methods, variables and properties.Not sure if there is some metadata available to hide those classes from auto complete. That would be sweet.

I'm getting the classic preloader problem of having the preloader not display until a certain percentage (in this case %30) of the total file has loaded. I am importing the TweenLite class in the second frame, and I am also dynamically attaching MovieClips from the library in that frame as well. I've tried putting a frame between the preloader and the title screen and using the Publish Settings to export all the classes in frame 2, but it does not help at all.

for first time decided to start using Classes to add my code instead of adding it directly in Flash and I really thought I knew how to handle this since I have created some re-usable classes before where you target an object by passing parameter etc,I thought that if I had one function (method) in my class and I wanted to call it from my .fla file all I needed to do was to create an instance of the class and then call my method.[code]But this doesn't work I get a message that says that it is missing arguments.how to use my code directly on a class and what are the differences of doing this versus putting the code directly on my .fla file and if it's even a good practice to do this?

i am using get and setters in my as3 code to edit values of an other class (because those variables are shared) i dont like to put stage.sharedVar.isScrabble in my code every time to change a variable so i used get/set functions [code]as you van see it has a lot of duplicate code every time the "return stage.sharedVar." and the "stage.sharedVar."+ the value + " = val" is constantly comming back.i was wondering is there a other way of creating these get/sets?[code]

What I need to do is assign 5 separate dynamic text fields to 5 seperate buttons and at the same time to those same five buttons i would like to add 5 images that i would be able to change merely by swapping out the images in the file theyre in on the server.I would also like to get a nice transition between the images...ALSO i want to dynamically load the images for the buttons that will be used for switching from picture to picture(which im thinking i will be able to do after i know the how to do point the aforementioned things.)
Through tutorials I've found around the net I've been able to get most of the parts together... but i get lost because what they show you for AS2 they don't for AS3 and vice versa, at least that ive seen.so... I guess my question is... would i need to set up 5 seperate dynamic text fields on the stage and then set each one of them to one of the corresponding button. If so what AS code would i need to use to do so. And if not what would i need to do?
The other part of the question would be I know about the UILoader... would i be able to use it as my buttons and images, if so would i need 5 seperate ui loaders for both the Thumbnail buttons and the images or is there a way that would be better to do it? and once i do that would i do the transitions using frames and tweens like with AS2?

If I create a new flash AS3 file and create two blank keyframes in my actions layer I can add actions to each keyframe separately no problem. I can then easily switch between the actions frames from the menu bar on the left of the actions input panel. However if I try and do this on any of my projects i've been working on for a while when I create a new blank keyframe in the actions layer and try to add actions to it, I get sent straight back to my first actions keyframe and not a nice blank page. Can I even apply seperate actions to seperate keyframes?

This is NOT the same as my last thread as i am after three and NOT ONE as last time. In the attached movie there are three seperate movies loading into three seperate tweens. Please note that i am happy with this movie as it is, and do not want to change anything about it except for the script itself. It refurs to three seperate clips "b.a","d.c" and "f.e". What i want is for the script to incorperate all three clips under one name of "mc" And instead of have three seperate widths, "width 1","width2" and "width3" i want the script to also incorperate all three widths and heights into just one name of "width" and one name of "height".

Is there any way to auto-import as3 classes (internal/intrinsic Flash Player classes at least) using Emacs ?
Looked for as3-mode and actionscript-mode but nothing working was found. as3-mode can import class if it is opened in buffer (but not *.mxml files)
