At the moment, my main classes game variable, is static, so I can access any class in the game, from any class in the game. However I keep getting errors related to the fact it is static; is there any alternative to this?
View 5 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 RepliesWhat I was told, which sparked my curiosity on this topic:Java gui classes can implement hundreds of Listeners and Callbacks and many books teach you to implement all these interfaces in your gui class. Alternatively, these aspects can be implemented in inner classes, so methods called by that listeners do not get mixed up.'d like to know how to do this in ActionScript, which doesn't have inner classes, but has private classes. But, I don't think I fully realize what inner classes are about, so I'm merely trying to wrap my head around the situation where I would use them to organize a class' methods by their usages.
View 2 RepliesI have a Flash application that creates a sort of powerpoint presentation. All the 'slides' are stored in an XML files which is read and processed.
I'm trying to build the presentation using this XML file. At the moment, my main class has it's initial function main and a static function processXML main initiates my database class with a function called initDB. One of my issues is that initDB forgoes processing because it's dependant on an event listener. On completion of loading the XML files, the event listener initiates my static function on my main to create objects from this file.
The issue is that because the event listener continues the processing (after an indeterminate amount of time), the functions are no longer controlled by the main class.

How do Static classes work in projects where child swf's use the same Static class as their parent?
For simplicity... lets say we have some older content swf files that are using TweenLite version 8 ( a common enough Static class.) But the parent SWF is being updated and uses a more recent version of TweenLite (version 10). The child SWF's are loaded into the parent SWF. Do the child SWF exist in there own sandbox and have TweenLite version 8 running and the Parent runs it's own copy of TweenLite 10? Or does the parents clips Static class of TweenLite (version 10) overwrite the children Static class using some sort of magical shared memory space when JIT (runtime) compiling?
I've rarely used static variables or methods when creating external classes, but I have on occasion, and it's very useful when I need global access to a value. I've seen negative criticism on the use of the "static" keyword, but never understood why. Is there a right and wrong way of using it, or is this not true? I'd like to use it in a context similar to classes such as MouseEvent or TextFieldAutoSize, where there is a list of values globally accessible for identification purposes.
It allows better code readability, and also allows for easy customization in the future. The value of TextFieldAutoSize.NONE is "none", but as long as a programmer used the reference TextFieldAutoSize.NONE and not the string literal "none", Adobe could change the value of TextFieldAutoSize.NONE to be "hahahahaha" and everything would still work just dandy because (TextFieldAutoSize.NONE == TextFieldAutoSize.NONE) is still true even though ("none" == "hahahahaha") is not.
Is there any kind of negative impact on using static variables this way? Or even functions for that matter? I'd just like to clarify this before I go and build a large project around the idea this is perfectly okay.
I load many classes in at runtime from external SWF's, accessing those classes is pretty simple, like so -
var currentDomain:ApplicationDomain = ApplicationDomain.currentDomain;
var modelClass:Class = currentDomain.getDefinition(className) as Class;
var model:Model3D = new modelClass();
However I've never tried to access static functions from a runtime class, and now I need to. How is it done? It seems like something that should be simple, but I haven't worked it out yet.
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.

I have a site with ScrollPanes, that are calling a Class on what to display. (so the movieclip that I want displayed in the ScrollPane has a Class name.) Within that movieclip (webScroll) that is being displayed in the scrollpane, I have 2 other movieclips (web1 & web2), with unique instance names and eventlisteners targeting those instances. when I preview my site, i get this error: 1119: Access of possibly undefined property web2 through a reference with static type Class.

how bad is this practice? I am having trouble getting to some stuff so i am taking the easy way out
Code:
private static var _interrupted:Boolean;
public static function setInterrupted(value:Boolean):void{

Let's say you have the following situation:
1. Static var(an Array) stored in a class.
2. You create a variable reference to the static class in a separate class.
3. Splice some items from the reference variable in the separate class.
4. Trace the static class and the items have been removed from that too.
5. Verify several times.
6. Get confused.

Ok, so I have a bit of a mess here (Which I'm probably not doing right anyway, which could be my problem...). I have a document class, I'll call it as Body.as, that creates an object from another class known as Headgear.as. There are also other objects created from other classes, or will be in the future. Now, amoung all this, Headgear.as and all of the other classes Body.as will use to make objects require the use of dragging functions (starting and stopping dragging). On stopping drags, position checks are then made to compare a particular hidden movieclip with the dragged MC.
To try and save myself some hassle (from making the same functions over and over to ensuring that when the objects are created I don't need to send a complete crapload of variables just to ensure the position checking function would work), I had the functions for the event listeners (Which are set-up on the draggable MCs in Headgear.as) just direct to functions in Body.as

If I created a static method. say I decide to call on other methods within that static method. Do those methods I call on need to be static as well? what If I used some of the properties. Not to store data permanently, but just within that process. Do those properties need to be static ??
View 3 RepliesAlright, so I have a class that is linked (via the linkage panel) to a scrollbox class. I'll paste the class here:[code]Ignoring the formatting, the commented out functions are the ones causing the issue. Adobe says that it's a static class and I can't use non-static functions. The way I wanted to use it was:
1. Call the page button generating function above.
2. In the main code in my program is this line:scrollbox.setClickFunction(historyContent.generate Page);So when the buttons that are supposed to be generated are clicked, the scrollbox class can call the History pages generatePage function and pass it which page to show. (I did this because there was a lot of text and a limit on how much would display, so small chunks sounded logical).
3. In the onClick function (which I haven't finished yet because the rest wont work), when you click one of the buttons it calls the set function. Its that simple.
I'm kind off oblivious as to what I'm doing wrong here... I have two classes: - Alley - AlleyCat

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..

I have created a Flash application for a "big" client which communicates heavily with the server. Flash app is initially loaded with a big XML file, which is retrieved by an aspx file. Then every 5 seconds, it calls a different aspx file to update. There are 3 asp files, which also sends back XMLs, that it calls periodically on top of the aspx file. Buttons on the app calls 4 different asp files with data being sent via querystring, but, uses the XML.sendAndLoad commands since we want the communication being done behind the scene.
During testing on development and live sites, we noticed no problems. We had sporadic complaints about the application being slow, but, they were so rare that we let it slide.
Now, it seems more frequent. I went back to the application and tried utilizing the built-in garbage collection by deleting all temporary variables, but, that didn't seem to improve much.
Given this scenario... is there anything I could try to improve the speed of server communications?
I have an application requiring exporting of Flash animations to run on an embedded media player. This accepts a number of video formats. The most reliable I have found so far is DivX. The player supports DivX versions 3.11, 4.x & 5.x. The export codec in CS3 is DivX 6.8.5 which is not compatible with the player.The player also supports MPEG2 but the quality is not very good. Other options are Xvid Mpeg4 video (doesn't work) and MS Mpeg4 video codec V2 & V3 (also not supported in CS3).I have tried downloading a variety of alternative second source file converters but frankly tied myself in knots. Any idea how I can get around this problem and get a DivX 5.x codec to work natively within CS3?
