I have written 3 classes classA, classB and classC.how can I refer to class A's doSomething method. ie to get output "classA.doSomething()"
View 4 RepliesI'm a programmer familiar with object oriented programming, with experience in C++, C# and the MS Visual Studio development environment.
I've been tasked to create a web based game using Flash CS4 and ActionScript3. I am new to Flash, ActionScript and game programming. I have never used previous versions of Flash or ActionScript.
The game will be a single player role playing game. The player will have the ability to create an avatar. The player will move the avatar from screen to screen based on button clicks or drag and drop onto objects in the current screen. Players must register, and player information will be stored in a database backend. Additonal data will be saved to the backend database during game play.The saved data will be based on player actions in various screens, and in some cases data entered in a form on a screen.
For a first pass a stick figure avatar and screens containing simple buttons and simple objects to drag the avatar to will be sufficient. I would like to store data in a database tracking date/time information, e.g. date/time each screen is entered/exited.
I have no background in programming and at 49 it seems that I am having a hard time understanding AS3, especially AS3 OOP. I wonder if I should give up at this point. I have been studying AS3 for 3 months now. Here's what I don't get right now.:

How can I apply OOP(Object Oriented Programming) in flash actionscript like as in Java?[code]...
I know there are a billion questions regarding what books are best and I'm sorry for posting another, but all of them see to have an orientation to a language I am not familiar with.
My problem is I learned to program before OO became big, then I stopped programming for a few years, moved into web design, moved into coldFusion, and now find myself in PHP, actionScript and FLEX.
I have muddled along for quite some time, but I am really struggling with my understanding of OO and would like a good book that will help me out with it. If that book is geared towards Flex and AS3 then that would be awesome, but if it had no language specified either I would be happy. I'm just not sure how reading a book oriented to Java or whatever is going to help my understanding of AS3.
Any links to any tutorials that teach how to create a full site with Object Oriented Programming? I am one year in now on Flash and AS3 and think I am getting pretty good at the basic AS3 principles and creating dynamic sites. Now I want to start migrating over into OOP so that I can create the more dynamic and browser friendly Flash Sites, but OOP is much more complex and would like a good example or sample of how to finish a full site under OOP coding.

I recently read some forum thread and article talking about Data Oriented Programming. This think seem realy interesting. I tryed to find some exemple, but i did not find any one using ActionScript. I would like to know if it is a good thing to use DOP with AS3 and how exactly this could be done?
View 14 RepliesI really get confused with these type of statements :
What does this mean :
when casting :
var xyz = ClassA( obj as MovieClip );
when declaring/defining :
var xyz:ClassA = new SomeOtherClass();
I mean, how 2 different classes are used in the same statements above ? Is this possible because of inheritance relationship ?
does anybody know about any good open source xml framework for actionscript? I find the one that comes with actionscript is quite cumbersome and unintuitive so I was wondering if anyone there is a framework that loads xml files into objects in actionscript 2.0 if you know of any such framework
View 2 RepliesI'm new to the object oriented stuff and I'm trying to learn how it works. Here's what I've started on - it's led to a few dilemmas. I have one flash file and two .as each with one class. In the timeline of the fla file, it reads:
ActionScript Code:
var FileObject:ScriptFile = new ScriptFile();
function onEnterFrame(){
FileObject.CallInput();
}
Call input is a function in "ScriptFile.as" that calls another function in "Input.as";
ActionScript Code:
class Input{
public function Input(){
} public function keyListener(target:Number):Number{

In output, when I press Left, it will say -5 over and over again, and I'm trying to add to xpos value but that isn't happening.
Clearly i'm a coding Novice, and I am going absolutely insane trying to figure out The Object-Oriented Scrollbar. I have the caurina folder in the same directory as my .fla , but when I publish I get these three error messages:
1172: Definition caurina.transitions could not be found.
1172: Definition caurina.transitions could not be found.
1120: Access of undefined property Tweener.
When I change my publish settings to find the files I get this message: 5001: The name of package 'caurina.transitions' does not reflect the location of this file. Please change the package definition's name inside this file, or move the file. /Users/npenta/Documents/AKA::Truth/Web/caurina/transitions/Tweener.as
I have followed correctly the Object-Oriented Scrollbar: Part 1 [URL] and Part 2 [URL] tutorials and I seem to have a problem when I want to use it with code. I have in my library the following objects:
ScrollBox:Linkage ScrollBox ;
ScrollBar:Linkage ScrollBar ;
Thumb ; Track ; Masker ;
Long (the long content that I am displaying with a scrollBar)
I create a new scroll with this code:
Select allvar scroll:ScrollBox = new ScrollBox();
for(var i:int = 0 ; i<= dictionarXML.length(); i++){
//This are some actions i have in my .fla (the DictionaryWord is a custom class)
var word:DictionaryWord = new DictionaryWord();
word.engleza.text = dictionarXML.cuv[i].engleza;

Ive gone through the Object-Oriented Scrollbar tutorial on [URL]. Its working great and I have multiple buttons inside of the moveclip it lives within. The problem occurs when I create another one on the same page. I have put one on frame 1 and the other on frame 5 so that I can select a 'category' and the scrollbar movieclip changes to the relevant buttons.Ive duplicated the movie clips and changed the instances accordingly. I keep getting these errors in the Output panel when playing my swf;TypeError: Error #1009: Cannot access a property or method of a null object reference. at as3_movieplayer_fla::MainTimeline/frame1()and when I click the like to the second category it comes up with this error;TypeError: Error #1009: Cannot access a property or method of a null object reference. at as3_movieplayer_fla::scrollbox_1/thumbUp()Not really sure what im doing wrong - or even what these mean!Here is the code from my main actions layer;

I tried the tutorial on [URL] The Object-Oriented Scrollbar: Part 2 tutorial. Every thing is fine, but when I load the swf to main.swf
- I can scroll the scroller, but not the content
- I got this error

I am using an Apple PowerBook g4, Flash CS4, ActionScript 3 and I am trying to develop and design my own site and truth be told I have no idea what I am doing nor how I will put all the pieces together. But at the moment I am trying to make a horizontal scrollbar using the Object-Oriented Scrollbar: Part 1 tutorial. Basically all I have done is used x instead of y within the actionscript code. However, the only error I am getting is with the import caurina.transitions.Tweener*; code. What comes up in the compiler error report is:
Location) Symbol 'scrollbox' , Layer 'Actions', Frame 1, Line 1.

After placing the unzipped caurina folder into my project folder and that not working I have placed in Applications/Adobe Flash CS4/en/First Run/Classes as I read within the forum post "Re: Object-Oriented Scrollbar Part 1" posted by AKA//TRUTH on Wed Jan 20, 2010 12:30 pm.

Simply put, what I'm trying to do is create a Dynamic Textfield with custom scroll bars via this tutorial [URL], that renders an external HTML file with CSS attached as its content instead of images like in the tutorial. I've tried a mix and match combination, ultimately, when I test the movie, the scroll bar works, but I see no content to scroll through. I have attached my project file.

I'm doing this object oriented game and I create a bunch of 'boxes' via a for loop
Code:
Select allfor (var z=0; z < numOfBoxes; z++){
var box:Object = new Object();
box.mc = new Box();
box.mc.name = "box"+z
box.mc.x = Math.round((Math.random()*(530-box.mc.width)) + 20);
for (var i=0; i<boxXArray.length; i++){
[Code] .....
I get my random amount of boxes scattered over my stage (I haven't put in any checks to see if they are touching). How do I 'name' these boxes so I can reference them later? Say I want to move the .x of boxA in another function? Is there a simple way to call them box+z instead of just all as box? (Then I can run them through a loop later to talk to them).
I am dynamically creating a movieclip, say, a ball. I want to apply a movement to each new ball created. I have created a movement function and now I need to know how to use this function as a method on each newly created ball. Would I do something like this:

ame_Manager.as= this manages the creation of balloons, players and collisionsBalloon.as= This is the balloon classPlayer.as=This is the player classThe Game Manager class will pass stage to the balloon and player classes and create them. I add these two in the Game Manager class.In the balloon class i add all the balloons in an balloon array.Now when i run the code i am unable to check for collisions as nothing happens when the player and balloon collides. and i get a child must be a caller of the display object when i ry to remove the balloons after they have crossed the stage.I have been trying to make it work for a long time a the game is very very simple.in the Object Oriented way of designing this simple game as i think that is where my error might be.I will post the code for these belowGame Manager.as

I have no experience with Object Oriented Programming, so I wonder about the following:
1) Will the code past the .LOAD line (in red) be executed only after the image completes loading?
2) Can I nest several listeners as seeing in my code below?

As stupid as my question might sound, i have spent the last 2 weeks reading oop books; but could use some guidance. I have a flash project that is basically a supped up slide show. On the stage i have the following: main_mc (instance name = images_mc) = movieclip which holds "pictures" ui1 (instance name = ui1_mc) = user interface that allows user to draw on picture (when drawing is enabled) ui2 (instance name = ui2_mc) = activates invisible hit areas (buttons) on select pics, when hit area is clicked, we jump to another pic in the main_mc.
I accomplished all of this on the timeline, but am updating the code to OOP. I am having A HELL OF A TIME trying to figure out how to store references to the instances (images_mc etc..), so i can control them from varying class files. I have found it is easy to control the instances from the documentclass, but not from unrelated class files. Example: images_mc.stop(); works in document class; but ovieclip(Parent).images_mc.stop() doesn't seem to work from any class file.(ui2 class file for example);

I have read at multiple places tutorials/explanations on the EventDispatcher use in AS3 and that confuses me a lot. how I should do to just send a simple message from a ClassB to a Class A. In the exemple below that I made, I have classA that calls classB to send a message that ClassA then gets. Of course, I simplified to the minimum the 2 classes to allow focusing on the problem. Currently, the exemple does NOT work, i.e. the line "trace ("message was received!");" is not executed. I saw in several exemples on the web that some put the addEventListener on the EventDispatcher object. I do not understand the logic behind this, I would put the addEventListener on the objects that will receive the message.

Im having a little bit of trouble trying to make a button give me different results based on what frame the main timeline is on. I am trying to get a button to go to a different link based on what frame the main timeline is on. If I am on frame 5 It will trace back "4" .. that is fine but other frames trace back the frame number and also 4.
frame 2 click of button traces back 1 and 4
frame 3 click of button traces back 2 and 4
frame 4 click of button traces back 3 and 4
frame 5 click of button traces back 4

is it possible in as3 to override a variable defined in a super class simply redefining a variable that has been defined in super class creates this error
ActionScript Code:
1152: A conflict exists with inherited definition classA.Type in namespace public.
i know i could use get/set methods or pass class type through constructor but thats not an elegant way to do what im trying to do.
