I want to create a game using pure AS in FlashDevelop.
The problem is that there are some methods I want to use, and because I don't like copying/pasting code, i decided to define in classes. Here is an example:
[Code].....
When I hit compile, I get an error like Call to a possibly undefined method distance through a refference with static type Class.
I'm making the game Breakout as an AS3 application using OOP. I am getting very confused though. I know that objects should be only responsible for themselves. But this is where I get stuck, they need to communicate as some level to add and remove screens, and I am getting majorly confused as to what is going too far, when it could maybe achieved in a simpler more OOP way. I've worked out the hierarchy of my classes, in terms of where they are being added (I think). I've added a screenshot of the hierarchy.
Have I got the order right based on OOP principles? Like, Introscreen will listen for play being pressed then call a method of the document class that will remove introscreen and then attach gamescreen. Is that right? Another thing that puzzples me. It seems to me if I made a level and put the paddle and the ball in that, then arranged all the bricks in that level, that I'd be duplicating work (based on the fact I need paddle and ball for level 2 also). So it would be best if I could have gamescreen with paddle and the ball and then add level1/2/3 to display list which would therefore set up the appropriate brick placement. But then, wouldn't that mean that I couldn't do hittests because my level 1/2 or 3 wouldn't be a sibling to the bat and the ball, them residing as a sibling in the level's parent class?
Is there a way in AS 3 to list all classes and their associated methods? Or at least a way to list the methods within a particular class?
It seems that it's all so overwhelming and although I'm well versed in Lingo and have a handle on the Lingo dictionary,I feel as though the AS 3 library is dauntingly big.
I have this problem from time to time with AS3 where I extend a Class and then try call methods and variables which are public from the new class but I get errors that method or variable doesn't exist. My IDE recognises the methods and variables though.[code]When I run the script flash hates it. I thought when you extend a class it was supposed to inherit its properties and methods?Does anyone else have these problems? I shouldn't have to cast it as Box. I swear I have this working in a project but cant see the different in setup?
View 4 RepliesIt's not clear to me, where I have to define Classes and Constructor methods. In AS2 it was possible, to define a class "light" by defining a constructor method. In AS3, I read, a class can only be defined in an external AS-file. Is it still possible to use the constructor method inside the Flash-File or do I have to source out all my constructor methods and implement them into real classes into an external AS-File?
View 4 Repliesmy understanding of extending classes is that you gain all the functions and methods of that class thus You could over ride any one of them. How ever I am confused on weather or not you inherit and can over ride private methods of the class you are extending or if you have to have all methods public in an extended class.

From what I read, interfaces are basically classes for methods, right? If two classes implements the same interface, then they should both have methods described in the interface.
Now, how is this useful? Let's say I want to call foo()

I am trying to do an app that requires me to change the behavior of a few native methods and classes of a an application.I want to override methods such as:ExternalInterface.call, ExternalInterface.addCallback, flash.net.navigateToURL in a loaded movie.There are a few ways to do this for example:1. Getting the SWF's bytecode and decompile it. Then change the symbols table with my own class.2. Loading the other movie in my applicationDomain, by doing so, I would be able to rewrite it's own classes.o do (2) what I did was:1. Turn off the "-strict" flag.2. Turn on the "-es" flag.in the compiler and then do something like:
Code:
flash.net.navigateToURL = function(u:URLRequest,window:String):void {
throw new Error("yay it works");

I have a question about classes. I just learn that static means that functions and/or properties are specifics to a class, but is it a synonym of private? And why statics (not available to any instances?) properties and/or methods can have a public (available anywhere else (timeline)) access modifier? PS: I just start with classes.
View 6 RepliesI have an application using a class that was originally a MovieClip exported for Actionscript by Flash. I have not been able to figure out how to add new properties to this class.
View 8 RepliesImagine I have a game with a base Entity class, with an init method that takes no arguments. Now I have a Wizard class, but I want to pass in 2 parameters, say speed and strength. In AS3 (and I believe Java and C#) I will not be allowed to do this - it is an "incompatible override" because the method signatures won't match. Now I could just make an "initWizard" method instead, but then I have the problem of the init method of each class potentially having different names. I need solutions that work in AS3, Java or C#.
View 2 RepliesYesterday I found myself wondering, what is the difference between either having a class with methods that are all static, or simply giving your class the static attribute?
View 9 RepliesI've recently started practising test driven development - thus far I've been working on a library project, so I've organised my FlexUnit tests in a separate FlexBuilder 3 project, linking against my library's swc.Now I'm working on a web app and wondering how best to organise the tests for this. At the moment I've put them in a src/test package in the project I'm testing, with the test runner application at the same level as the default application. Is this the best way to do it, or should I have a separate test project and link in the source for the application I'm testing?
View 1 RepliesBasically an array if fed to callThumbs() which iterates through it and compares the entries with preloaded XML _my_images. If match is found, it's sent to processXML which loads all relevant info and loads a .jpg thumbnail. All this is then fed to createCell which creates a specific cell with position values depending on x_counter and y_counter values (4 cells in a row) and adds the cell into a container _container_mc.
The Problem: This all works fine and looks fine, the problem is that the cells within the container do not display in descending order. They are in random order, probably because some of the .jpg's takes longer to load etc. How do I easily organise the cells within the container in descending order by the XML .id value? Or how do I tell Flash to wait till the thumbnail and data is loaded and the cell created and added?
//Flash (AS3)
function callThumbs(_my_results:Array):void { // selector = 1 for specific items, 2 for search items
var _thumb_url:XML;

What's the best way to organize functionality modules in a flex project? I saw some people put all modules in one view stack ,and so the application interface is only load once, but when the application get larger, the whole compiled swf would be very big. If we put swfs in different pages, we pass request parameters through HTTP request, we lost the benefits from flex RPC services, slow loading, and we can't see any superior comparing to php,asp,jsp... what's the best practice to organize front end architecture?
View 3 RepliesI really want to start work on a game idea I have using PaperVision.The largest/most complex thing in Flash I have ever made is probably my last project which is an interactive school map for my A Level [URL] . Check it out, its a little laggy in the browser but it is designed to run in the flash projector from the desktop.I used around 10 .as files and dumped all my graphics in 1 .fla as sprites and stuff.This is ok (...ish) as I had a large 'main' file and a massive 'main3d' file which (324 lines which is big for me :S lol).
Im planning on making it a big, 3D adventure style game with lots of elements and AI things. But how do I organise my code? If I continue like this, I'm going to have a few mahasssive files and lots of small ones.How to the 'pros' organise their stuff? All the time I see source codes for small experiments which are great, but I have never seen any layout overviews of what files they used and what kinds of things they put in them. I also have no idea how complex environments, where objects need to update to add/remove elements without having to check the position of the player every frame.
How should I go about organizing the scripts for an invenotry system in an RPG? Should I use arrays for this? I've already assembled a basic movement system and a basic item inventory system... now how do I go about assembling this system?
View 5 RepliesIn an attempt to organize my code, I'm trying to split up my (lengthy) main controller class into separate files, but my new files must still have access to the variables and functions of the main controller class.I'm trying to cut and paste code from my controller class into a new class/file, allowing the controller class to call the new class, and allowing the new class to have access to the controller class's properties and function.Assuming I'm not totally bludgeoning appropriate design patterns, below is my unsuccessful attempt at accomplishing this task:
package
{
import flash.display.Sprite;
import flash.events.Event;

I have a task. I must make an interface/application with a list of songs, alphabetically sorted by Genre / Mood. That also gives you the possibility to add more Genres/Moods and it should be easy to browse them. When a specific Genre/Mood is selected, the corresponding tracks appear, and when a specific track is selected, it should play in a player (see description below), and information about this track should also be displayed.
There should also be a Player included with Start/Pause/Stop buttons. It should be possible to see the full length of that track (time duration). There should be a loading bar and visible progression bar (like on Youtube) and it should be possible to drag in the progress bar to get to the specific point of the track. Is there a template for this sort of thing? Or how do I make this sort of menu? I guess it is some XML combined with some ActionScript?
I have more sites, sites have some users, and each user has separate application folder
What I want is put application folder in a defined folder like following
C:FMISsiteAapplicationsuser1
C:FMISsiteAapplicationsuser2
C:FMISsiteBapplicationsuser1
C:FMISsiteBapplicationsuser2
etc...
I think for this I need to create virtual hosts.
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)
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).

I'm trying to import a class from a class that is located in another folder. How do you move up a directory? Using./ or ../ doesn't seem to work. Essentially I want to access a TweenLite Class but not from the document class. My class is at com/myName and the class I want to access is at com/TweenLite. import ../TweenLite doesn't work... I realize I could just copy and paste the entire Tweenlite folder again, but there's got to be a less duplicative way of doing this..
View 2 Repliesinheritance and building classes from other classes.
I have 3 classes:
gfxRoomText - changeable colour
gfxRomInter - changeable colour - interactive
gfxRoomImg - interactive - only image / no colour
The first two incorporate the same text field and functions to change colour. The second and third incorporate another class to interactive with. What is the best way of creating these classes using inheritance and how?
I have to use many custom classes for a project, each class includes lots of elements(methods,properties) and I generally forget their names when coding. Is there any editor which I can enumarate the elements of my classes after pressing "." like Flash's built in classes?
