How can I replace
public function Mainclass()
{
Calculations.getDistance(5,9,4,2);
}
[Code]....
I'm not lazy (lying? :p), but I use the class more than 20 times, and it looks better if I replace al these long classnames.
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

Ok, so here's the problem. What happens in the above, is that I call 'loadTheXML()', it loads the xml file into xmlLoader and then runs the event handler 'onLoad'. My problem is here: once I get into the event handler 'this' refers to xmlLoader, not the class. Therefore, I have no way of calling wannaCallThis(). How do I call a member function of the class from inside the eventHandler?
Code:
package
{
import flash.display.MovieClip;
import flash.display.Graphics;
public class Rail extends MovieClip
[code]...
this is a simple Rail class, what I am trying to do is take the for loop out of the timeline and build into the Rail class itself. How do I refer to the Rail class itself within the method? If I am doing this the wrong way please let me know! Would it be better if I created another class, say a "RailSpacing" class and build the for loop into the contructor into that?
Also, if I wanted to add depth to the rail(textures or something else to make it look real) and still be able to change the color without transforming the entire rail instance, what could I do ActionScript wise. I have come to the conclusion the only way to do this is creating a multilayered movieclip and target the base object and not the highlight/ shading layer.
Also, if I created a nice graphic/movieclip and exported it for ActioSncript, how can I find the class file and add too it? Is this even possible? Is it possible to draw something that is detailed and export it and then add some methods?
How can I access a timeline variable from a static class / singleton?
View 14 RepliesI have an actionscript class with a static member variable defined.
public class A
{
public static var x:int;
}
When I try to access it from different parts in my code I don't get the same value in each spot.
A.x
I am accessing the variable in different modules that are loaded, so they are all in their own separate .swf file.
In the following code (thoroughly debugged) the first case (1) in the switch is met and a new instance of BannerSingle is assigned to retVal (the return value). Unfortunately, while the second case (2) is never met, the assignment therein to retVal takes place and I can't compile. When I comment out the assignment to retVal for "case 2:" everything works fine.
I've tried using an if/else instead and I still get the same odd behavior. Also tried a number of solutions involving separate variables, etc.
package fl {
import fl.IBanner;
import fl.Banner;
[Code].....
I have 3 swfs, and let's label them MovieA, MovieB, and MovieC. MovieB is a child of MovieA, and MovieC is a child of MovieB. So the hierarchy goes like this: MovieA -> MovieB -> MovieC. Each of these movies have their own document class, so they are each essentially a class extending MovieClip.
Now I have this other external class which contains only static variables. Let's call this class "TestClass" and let's say one of its static variables is called "testVar". So in MovieB's document class, I imported TestClass and set testVar = "hello world". In MovieC's document class, I imported TestClass and traced TestClass.testVar. When I publish and run MovieB, testVar is successfully traced as "hello world". Now when I publish and run MovieA, testVar is traced as undefined.
I'm currently working on a particle system for a game that I recently started development on, but I've hit a snag: I have a class particlecontainer that tells each particle what to do on enterframe, and which contains each particle as a child. I also have a class (mischandler) which has a static array that contains all current particles, as well as another static array that is a buffer to remove particles from the particlecontainer. Whenever a particle "dies", it calls a function which adds it to the buffer array in mischandler. However, when I try to access this buffer array from the particlecontainer class it does not recognize it as having any elements. If this is unclear here's a simpler explanation:
particlecontainer tells a particle to do it's enterframe function particle calls die() and adds itself to the removebuffer inside mischandler particle container tries to access mischandler.removebuffer but removebuffer has no elements Strangely, the particle can access the removebuffer perfectly fine and sees all the elements in it.
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'm kind off oblivious as to what I'm doing wrong here... I have two classes: - Alley - AlleyCat

The Idea is i want to make avariable that stores his value after i close the swf and open ti again,
an example:
i make acounter
var i:int = 0;
var timer:Timer = new Timer(1000);
timer.start();
[Code]....
the value of i will increase but after i close the application and open it again the value will return to 0 , keep the variable stores his value after closing the application ?
I'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.
View 1 Repliesok I am having what I think is a targeting problem.I'm loading a swf into a blank container inside another movie (main). The AS in the loaded swf refers to positions of MC's in itself _x & _y etc.However once it is loaded, those positions are not true... ex. if the center of the swf is 200 by itself depending in where it is loaded, it might become 400 or any other number - reletive to the main movie's stage (I hope Im being clear).I need the AS in the loaded swf to refer to itself (x/y values relative to its OWN stage). So how do I target that? _root.MC.containerMC doesnt seem to work, but is this on the right track? Basically when an swf is loaded into another, does its _root now become the main timeline of the movie its loaded into???

I have a class named Locator that I use to GeoLocate a user. There's a static method in that class called "locate()". This method then calls another method which sets a static variable called "loc" to an instance of a LngLat class.The issue I'm having is, when I call the locate method at Frame 1 on the scene, and then try to access the loc variable it shows as null... but when I trace the loc variable after it's set in the Locator class it shows as an object.[code]and then trace the variable at the end of the static method in the Locator class it shows as a object and the city is traced as expected.
View 1 RepliesIt is possible to call variables using this[ "stringname" ] for instance, to refer to a variable called "stringname".
However, when referencing a static variable by the name "stringname", the "this" attribute no longer works if applied.
Is it possible to use this technique with statics?
I've been trying to create a script that pulls the current time and turns it into a variable, the problem is the variable keeps updating as the time changes, where as I need it to remain static as the time that is was when the variable was first created...it's just a simple:
Code:
var theTime = today.getTime();
In the following class
Code:
package
{
public class Factory
{
[Code]]....
A break point on the "Okay" line shows that x1 is null but x2 is equal to "<entity id="DRONE" points="100"/>".
If I take the whole block out of the switch statement, both x1 and x2 are equal to the expected xml.
I'm trying to change a static variable in the class's constructor. At the start I have:
public static var mainReference:Main;
public static var timerReference:Timer;
public var timer:Timer = new Timer(1000);
This is so my static functions can access main and timer. At Main's constructor I have:
mainReference = this;
timerReference = timer;
The problem is, the first gives no error when I compile it, but the second tells me Access of undefined property (timerReference).
Is there any way that you can have dynamic variables inside of a static function considering that you can't use "this" inside a dynamic function.
What I am trying to do:
public static function convertToDynamicString(pString:String):String
{
if(pString == "" || pString == null) return "";

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 know about static function.What is static class? What is the use of static class? how can i use static class.? Give me a static class example?
View 5 RepliesHi there, i am hoping for some advice on structure/optimisation from some of you experts . I am working on a portfolio system that is modular, each module works in a self contained way and does not require the other modules to function, though they can be 'linked' by having them all reference the same PortfolioData() class.
im happy with how it is working, but i feel there could be a better way to share the datasource between all classes rather than duplicating it and storing a copy in each class.

I am attempting to create cash register simulation game and am running into a problem with a conditional statement that I am using to check whether the correct change is being provided to the customer and if a button is being pressed or not. In this game, the user can see the amount of the sale as well as the amount the customer pays. With this information they have to click on the cash drawer slots which will increase a variable called changeCount by the value of the monetary unit they have selected.
I am using an if statement to take them to the next frame if the changeCount = payment-sale and the confirm button has been pressed. To check for the button I am using a boolean to see if it is being pressed or not. For some reason, it is not registering the updated value of the changeCount for the if statement to work. If I trace the value with trace(changeCount); it will return the value I want.
The source code is pasted below:
package {
public class CashierMain extends MovieClip {
private var confirmBtn:ConfirmButton;
private var pennyBtn:PennyButton;
private var dimeBtn:DimeButton;
