How do you go about creating a Class that just holds constants such as the StageScaleMode or StageAlign classes. I tried just making a class with just public static constants and an empty contractor but I get errors.
View 2 RepliesI am working on a Flash site template for which I am implementing the possibility for the users to change the theme dynamically while the site is opened.Basically, the site will have a few themes available and when the user selects a new theme, all of the site objects will change their properties (colors, alpha, fonts, etc) to fit the new theme.
And my questions is what is the best approach to sending the theme information to all of the objects in the site.I was thinking of making a static class called "Theme" and when the objects need a property, they will call a static getter of the Theme class that will return the appropriate property value for the object.But, from my understanding, static properties are quite slow and seeing that I may need quite a lot of them, maybe more that 100 for the whole site, will this approach be too slow ?
I have some code from a CS3 app composed of the .FLA file with an .AS file for the class that had definitions for two private classes in it. Yesterday I brought the files into CS4 and noticed that they did not compile. Gives an 1120, access of undefined property and names a constant. I have reduced this problem down to bare bones and it still occurs, so it is a bug in CS4.

Flash UI Components have many different styles to set, which require passing a string name to the setter method.while this certainly is not challenging, the use of a constants class would be beneficial but i can't find one.is there no constants class available with all of the possible style settings?
View 1 RepliesI'd like to make an object that has it's properties named by constants from another class but can't quite get it to work. I'd essentially like to do something like this:
var myObject:Object = {Event.OPEN:"value", Event.COMPLETE:"value2"};
This syntax causes compiler errors.
I have a class ErrorMessages which holds all my error messages as static constants. So I could access them like ErrorMessages.PASSWORD_INVALID or ErrorMessage.PASSWORD_TOO_SHORT. I want to know if it is possible to have separate classes that hold subset of these constants and access them like ErrorMessages.PASSWORD.INVALID or ErrorMessages.PASSWORD.TOO_SHORT, etc. This way I can more structured static structure and makes it much easier to use autocomplete. I tried few different ways and couldn't figure out if this was possible..
View 3 RepliesIs there a way to generate an instance of a class that implements an interface based on the name of the class?
I am trying:
var ClassReference:Object = getDefinitionByName("movement.OuterSpaceMovement") as IMovement;
var m:IMovement = new ClassReference as IMovement;
trace("startup..." + m);
-But I am getting an error message ReferenceError: Error #1065 (OuterSpaceMovement) not defined.
I have several classes that implement the same interface (IMovement) but I need to be able to generate new instances of these classes and then pass these instances as a datatype (IMovement datatype) to other classes...
So then I tried:
var ClassReference:Class = getDefinitionByName("OuterSpaceMovement") as Class;
var m:IMovement = new ClassReference() as IMovement;
and this doesn't seem to work...but the following
var m:IMovement = new OuterSpaceMovement();
I'm trying to create a new instance of a MovieClip when the original one has been used. Would sound easy enough. Just use: var
instanceName:ClassName = new ClassName();
the class name/mc in the library im trying to duplicate is MCg1 so
var instanceName:MCg1 = new MCg1(); right?
However, the particular object in the library i'm trying to duplicate has a base class that is an external class file (just to control it's drag drop functionality)... i.e baseclass is not set to the standard flash.display.MovieClip, or whatever the case maybe. So i end out with a: TypeError: Error #1009: Cannot access a property or method of a null object reference.
I'm creating a slideshow where each slide can have:- a video or a still- 1 audio track or many (up to 3)- 1 button or many (up to 3)I was thinking that each slide can be it's own object, and then I would pass the video, audio, buttons, etc., into it as parameters:
package
{
import flash.media.Video;

I have a class that represents a turret in the center of my screen.When I hold down SPACE, I want it to create a "bullet"-object that moves in the direction of the turrets cannon, every frame the SPACE key is held down. I am having problems with this cause I am getting this error when I am trying to create the object:
Error #1009: Cannot access a property or method of a null object reference.
This is where the error occurs:
ActionScript Code:
public function chaingun(x_:int, y_:int, rot:int, cd:Number, spd:Number, sprd:Number, life:Number) {
this.Cooldown = cd;
this.Speed = spd;
[code]....
PS: What happens is that when I press the SPACE key, the "turret" class event handler runs the function "Shoot_Chaingun" and that function creates a new Chaingun-object (which actually is a bullet), that inherits the x, y, and rotation of the turret, along with some additional varaibles, including lifetime. Then upon creation, I use "addChild(this)" to add it to the main stage, and "removeChild(this)" once it's lifetime is up.
EDIT: And also, I just realized I don't have a MovieClip linked to this chaingun class. How do I make sure that every time a chaingun object is made, the MovieClip is also loaded?
Just wondering if there is a way to read class static constants from a SWF file server side. I have found things like getimagesize() but it doesn't have all these details. I guess that means I need a partial decompiler.Specifically, I have this class in my Flex project:
package
{
public class AppVersion
[code].......
How can I have a constant in a Flex application which I could apply at several places in a Flex CSS file? For example I may have a background color which is the same in several UI components and then I would like to have this color set in only one place and reused in all style clauses. Something like ...
public static const myColor = "#00FF00"...
component1 {
backgroundColor: myColor
}
component2 {
backgroundColor: myColor
}
Basically I want to call a const by a int. Here is the code I have so far...
public static const _100:String = "name=lion legs*type=legs";
public static const _101:String = "name=lion tail*type=tail";
public static const _200:String = "name=tiger legs*type=legs";
///more lines going down with the number on the far left being the main differentiating factor
public static function getByName(name:int):String {
[Code] .....
Is there a better way out there to call the constants by an outside int without having a switch function handle the logic?
i can write constants in two ways:
MouseEvent.CLICK - "click"
MouseEvent.ROLL_OVER - "rollOver"
TextFieldAutoAlign.LEFT - "left"
etc.Is there any difference between the two ways of writing?
Despite if it is good practice or not, I read here that you can have package variables (or constants), so I tried this:
[Code]...
I want to create a function pointer object:
private var func:Object = { Class.Constant: function };
What is the clean way of doing this? I did the above and got
Error: Syntax error: expecting colon before dot.
And I'm not even sure that's right. The goal is that I can just do
func[ Constants ]();
I just found out that it is executed like a normal variable at runtime. Typically constants are supposed to be 'inlined'........ so when you write this:
ActionScript Code:
const SPEED:int = 5;
o.x += SPEED;
...you should get this in the SWF:
ActionScript Code:
o.x += 5;
...but when I decompile my SWF I get this:
ActionScript Code:
const SPEED:int = 5;
o.x += SPEED;
Is there a way to force the Flex compiler to inline constants in AS3?
How can I get the ord values of certain keys. Say if I want a function to run when the left arrow key is pressed or right arrow key. Or is there a constants list?

View 14 RepliesWhat is the most proper way to store "global" constants for a flash app:
a static data class
a dynamic data class
a dynamic data class via getter/setter
We have a project that has been built in Flash and as3. It is a video player of sorts that we want to fully customize. We have different images and color schemes that we want to be able to change very quickly. Right now we have config constants that we turn on and off for different schemes. And in the code there is a massive amount of different spots where the images and such are changed.When we create a new color scheme or whatever, we need to create a new config. Then we have to go through all of the code and put it in correctly.Basically any suggestions for how we can take the current flash project (maybe flex?) and make it customizable a lot quicker.
View 1 RepliesI am trying to set some public static constants on a class conditionally by passing variables to the compiler e.g. -define=CONFIG::ENVIRONMENT,'testing_server'
[Code]...
Obviously this means I have to tinker with long command line setting each time. I thought my initial approach was possible given the documentation and various tutorials I have read.
Say you have a web application that has a lot of business rules built around if-then comparison of String constants. These are used on both client-side and backend code, and at the moment are hard-coded badly throughout both places with lots of duplication and sometimes errors. What's a sensible way to refactor them out? Unfortunately, in most cases they must exist as using polymorphism would be much more hideous. Anything specific for flex/java? Is there an easy way to keep all those constants in one place and compile it into both client and server code?
Edit: I'm really looking for a way to share string constants between flex and java with compile-time checking of everything.
I would have expected, given the way Adobe seems to do things, that you could reference some of the non-ASCII keycodes using a static constant, for example KeyCode.UP_KEY. Am I dreaming? Or do you just assume 38 will be the up key in perpetuity..?
View 1 RepliesHow do you use config constants with values other than true or false? The only documentation examples I've found uses the syntax:
ActionScript Code:
CONFIG::CONSTANT_NAME {
//do stuff
}
But what if the constant is set to a value like "hello"? How can I set a block of code to only compile if the constant is set to "hello" but not "goodbye"? I tried:
ActionScript Code:
CONFIG::CONSTANT_NAME == "hello" {
}
I have a class that holds some constants and will receive an object literal (associative array) with some data like this:
var ConfigObj:Config = new Config({
"Some" : 10,
"Other" : 3,
"Another" : 5
});
The class looks like this:
public dynamic class Config
{
static public const SomeProperty:String = "Some";[code].....
I've defined two classes, one of which extends the other. The superclass defines a constant and I can't seem to access it through the subclass.
Code:
public class BigClass
{
public static const BIG_CLASS_CONSTANT:String = "Hi Mom.";
[Code]....
Shouldn't polymorphism allow a subclass to access constants of the classes they extend? Does the subclass have to reference the parent constant in some other way than a simple extension? Do I actually have to declare that constant in each and every class that decided to extend from that parent (but then how would the parent refer to it?)? Or (and this is the most likely) is there something completely different that I'm missing?
I want to create a rectangular box and add it to the stage. Easy enough.
At the moment I create custom classes and attach them to movie clips in the library via linkage, but in my example there is nothing to attach it to as it does not exist. How can I create a "generating class" like this?
I just want to call it with a call like
createRectangle() or possibly have some parameters createRectangle("200", "400")
I'm having a little issue understanding scoping in this package environment. My question is this: Is it possible to declare globally visible variables and constants? I tried this with no successful results:
