i am pretty familiar with tweaking as1/as2 performancehowever in as3 i am still a noob concerning optimization.i tend to have a class utils in my projects in which i carry a lot of static vars and functions.[code]
View 3 RepliesI'm wondering if anyone has experience with if there is a big difference in performance in ActionScript 3 between keeping a class with only public static functions, and utilizing those functions often (as in a frame event at 30fps), and in turning the class into a "normal" class of which I instead make an instance and call the functions via the instance instead.

I realize this is kind of an odd issue, but I am wondering if there's any way to get Flash to allow me to access a class's static functions using a class variable that points to the class. Example:I create a class called FooClass that has a static function named fooI then create a variable of type Class that points to it
Code:
var class:Class = Class(getDefinitionByName("FooClass"));
However, when I try to call foo() using the variable, it errors saying the function

To rephrase my question: if you have a class with a bunch of static methods and you use one of them in your code, does the whole class get compiled with your movie? I suspect that it would be and, if that's the case, wouldn't it be better (from a file-size perspective) to use packaged functions instead?
View 3 RepliesOk, 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

6. Network availability
I'm building an air app which will run on iPads. For the touch interaction I'm using just MouseEvents handlers (MOUSE_DOWN, MOUSE_MOVE, MOUSE_OUT, MOUSE_UP) because my app don't need multitouch, now I'm wondering if there is any difference in execution speed, should I use the equivalent touch events or the mouse events are faster?
View 2 RepliesI'm developing an application using Flas Builder / Flex for Adobe Air. This application will be processing a large set of static text (100 - 200 MB) using a variable set of processing instructions.The target platforms will be iOS, Android and Desktop.The data set can be either one large XML file or broken into a bunch of XML files about 3MB each.This will be decided at design time.From your experience would it be better to store the text in an Adode Air database or a set of XML files for best performance (including speed and battery life)?What other considerations should I take into account?
View 1 RepliesI'm creating a simple scratch game (6 cards). It doesn't even have to contain difficult logic. You eventually win all the time ;)The code i wrote works pretty well, but i keep thinking it could be better. I'm not too familiar with coding, but i'm learning step by step. Do you have ideas to write this down in a cleaner and more sophisticated way?.g. I tried to separate the IF statement that returns in every function, so i would only have to write it down once, but i didn't succeed
//set card variables to 0 and when they're scratched, they're changed to 1
var checkCard1:int = 0, checkCard2:int = 0, checkCard3:int = 0, checkCard4:int = 0, checkCard5:int = 0, checkCard6:int = 0;

when using nested functions in my code. It's very easy to want to do something like this:
ActionScript Code:
private function someFunction():void
{[codee].....
So, performance wise, is it necessary to null references to classes, etc inside a function? Something like:
Code:
function myFunction():void{
var myVar:myClass = new myClass();
//do stuff with myVar...
//don't need myVar anymore
myVar = null; //is this necessary?
}
Alright, 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 am using get/set functions to make variables that are (or appear to be) read only. I can get it to work with instance variables, but not static variables. I found this, which seems to indicate that it's possible to use get/set functions on static properties, but the compiler keeps telling me I have duplicate function declarations. This is essentially what I'm using:
package {
public class Foo {
protected static var bar:int = 0;
public static function get bar():int {return bar;}
}
}
It seems that Actionscript doesnt support defining static functions in interfaces. Whats the reasoning behind this?I think it would be useful to have that ability but I'm sure there must be a reason why its not there.

I'd like to have a class that will resolve calls to static functions that don't exist.If you have an object that subclasses the Proxy class, you can override the callProperty() method to catch calls to functions, as properties of that object, that don't exist.How can this be done with static function calls in a class? It cannot be done by making the overridden callProperty() method static. Is there another way?
View 1 RepliesI'm working with an application which was originally designed to make heavy use of static-variables and functions to impose singleton-style access to objects. I've been utilizing Parsley to break apart some of the coupling in this project, and I'd like to start chiseling away at the use of static functions. I will explain the basic architecture first, and then I'll ask my questions. Within this application exists a static utility which sends/receives HTTP requests. When a component wishes to request data via HTTP, it invokes a static function in this class: Utility.fetchUrl(url, parameters, successHandler, errorHandler); This function calls another static function in a tracking component which monitors how long requests take, how many are sent, etc. The invocation looks very similar in the utility class:

I 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.

Let's say I would want to use the frameScript method to add some stop and play methods to some frames.
Normally I would declare the stop function:
[Code].....
My question is, how can I create the same $FUN_FrameStop as a static function?
Static functions do not allow the use of this since static members are bound to a class and are not inherited by that class' instances.
So, is there a way to create a function similar to $FUN_FrameStop, but static?
How can I get around using an instance variable in a static function that must be called by the Delegate method?

View 3 RepliesI'm developing a game atm, and I need some help on the mathematics/coding of colliding circles (and their change in x/y speed). What i need to know is how to calculate the direction and speed a circle has after colliding with a static (non-moving) circle. I know how to detect a collision between the two, but I'm not sure about the maths I need to give the circle the right speed and direction after the collision
If i do know how far away the two circle-points (in the middle of each) are to each other (in both x and y coords) would it be easy for me to find the new speed and direction of the large circle in the example above? I know that I somehow should use the angles to pretend the circle hits a flat "wall" (as it only hits one point), and then calculate the new speed/direction. My only problem is that I'm not sure how to decide the angle of this flat "wall" and how x and y speeds should change when colliding with a wall that is angled. Does anyone here have any insight, links or tips on how I can du this?

View 6 RepliesI'm curious about event performance. I have a custom class that downloads files from a server and writes to your local system with AIR. This class has a few custom events that fire during a download process: File starts downloading, files finishes downloading, error occurred, progress, and a few others. This class was built for a specific project, but made coupled so it can be used for anything else wanting to download a file from a server. I'm starting to implement it into a new project, and a few events I'm not listening for, such as when the file starts downloading, or the progress of it, just the complete.
Does it strain overall performance having all the other events still dispatching, when I know they aren't being listened to? Would be be better to comment out the dispatchEvent() for the specifics I know aren't used, or does it even matter? There's obviously events dispatched throughout the SDK that aren't always listened for: Right click, drag, resize, etc. This makes me think it doesn't matter that these events fire but aren't handled, but since code is running and things are happening, that means there is performance going on.
