ActionScript 3.0 :: Object Oriented Scrollbar - Getting Error
Mar 17, 2010
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;

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

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;
stop();//buttonsbtn_advertising.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);function mouseDownHandler(event:MouseEvent):void { gotoAndStop(1);}btn_corporate.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler2);function mouseDownHandler2(event:MouseEvent):void { gotoAndStop(5);}//video player scriptfunction

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
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.leebrimelow.ui::ScrollBar()
at flash.display::Sprite/constructChildren()
at flash.display::Sprite()
at flash.display::MovieClip()
at com.leebrimelow.ui::ScrollBox() .....
The scenario is:
- The main timeline play and stop at 56.
- At 56 the main.swf loads the sec1.swf

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.
Discription0 1086: Syntax error: expecting semicolon before mult.
Source) import caurina.transitions.Tweener*;
The caurina file was downloaded the from Tweener Documentation and Language Reference site [URL] and I used the tweener_1_33_74_as3.zip Stable version 1.33.74, Actionscript 3 (Flash 9+) Featured Jun 2009 34.4 KB file. 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.
ActionScript Code:
Code: Select allimport caurina.transitions.Tweener*;
var xOffset:Number;
var xMin:Number = 0;
var xMax:Number = sb.track.width - sb.thumb.width;

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 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'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'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.

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.

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).

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 am having problems with a scrollbar tween on my site. I have tested the site ([URL]) on many browsers, and it tends to work fine. But, on a Firefox browser, I think with a new version of flash player, and also when I run the Debug on Flash, I get this occasional error:
[Code]...
This tends to happen if the user clicks on the scrollbar button, begins moving the scroller, and then, without clicking back on the scrollbar button to stop it, the user presses on a button on the left navigation. I think I understand what the error is telling me, that it can't complete a function for things that are not yet on the stage. But I am not sure how to fix the code regarding the Tween to get around this. Would anyone be willing to look over my files if I sent them? Here is the Tween code I am using:

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 read some of the other posts concerning scrollbars but they didn�t solve my problem. I created a simple horizontal scrollbar but it doesn�t appear on my screen at all. Instead I keep receiving the following error message (I translated it from German so it might not be 100% correct):
1046: Type has not been found or there was no Compiling time constant: ScrollEvent.
The error lies with "public function scrollHandler(event:ScrollEvent): void { ".

I have a main movie that contains a series of buttons that load different swf files into a loader component.
Each of the secondary movies contains a series of buttons that when clicked load a movie clip with information specific to that button.
Nothing earth shattering, right...
When I preview the secondary movie it runs as I would expect.
When I bring it into the main movie via the loader component and click any of the buttons to load the secondary movie's movie clip I receive the following errors[code]...
