Is it possible to change an inherited variable's type?I have a class, Switch, which defines a Boolean variable, _currentState. I then have a class, VariableSwitch, which extends Switch. I would like to redefine the variable _currentState as type int.
View 3 Repliesis it possible in as3 to override a variable defined in a super class simply redefining a variable that has been defined in super class creates this error
ActionScript Code:
1152: A conflict exists with inherited definition classA.Type in namespace public.
i know i could use get/set methods or pass class type through constructor but thats not an elegant way to do what im trying to do.
Im really new to as3, and im just trying out some stuff, but i cant get a shape to refresh and change when i change its variable using a text field.If i change the text fields text before i test it, it works, but while its running it doesnt change it again.Btw, trying to change the stroke size.[code]i just want is so that when i change the strokeSize_txt text box, it will change the stroke for the shape.
View 2 RepliesI've created an FLA as an AS3 project. It's been completed for about a year. I want to port it over as an iPhone.. and Android app.
When I try to start a new FLA and choose iPhone project or Android 2.5 project the project generates some weird errors.
Even if I create a new AS3 project and copy over the library and the keyframes it generates the same errors.
So .. I'm wondering if there is a way to open the FLA that is working and simply alter the project type to iPhone ... or Android?
I have been banging my head against a brick wall regarding the following problem which must be very simple to fix, just can't see the answer.I have a class assigned to a movieclip called canvas. The class is called drawClass. I have called the instance of canvas on the stage 'drawingCanvas'.When I trace "drawingCanvas" I get object drawClass] which is fine. Tracing drawingCanvas.name gets me the instance name 'drawingCanvas'.This is a String variable.Basically what I am trying to do is pass the MovieClip name to another class. In my example the class 'toolBar', which can then interact with the MovieClip.
The problem is passing 'drawingCanvas.name' results in a String, so I get an error saying :TypeError: Error #1034: Type Coercion failed: cannot convert "canvasArea" to flash.display.MovieClip.I can't for love or money find a way to convert a String variable to a MovieClip variable! I have the name of the MovieClip, I just need to tell the toolbar class. But I can't find a way of doing this as the instance on stage is an object of drawingClass, not a MovieClip (unless MovieClips with attached classes are not treated as standard MovieClips?).
I'm trying to achieve something i thought would be extremely easy, but i can't get it to work!

What is the ActionScript 3 function that returns the type of a variable ?
I remember that there is one but I can't remember it nor can I find any reference of it.
I have two objects [object MovieClip] [object ContentDisplay]
i have to differentiate them abut i can't find a method in as3 check variable type.
The task was meant to be quite simple: I needed to initialize variable with new keyword dynamically, depending on it's type. For example:
public var object:Sprite;
...
object = new Sprite();
In this case type is Sprite, but it could be anything and a method which actually instantiates it with new, doesn't know with what type it was declared. Of course I could store type (or class name) in string variable and instantiate object with it. But I just wonder if I could get that type info from the object itself, 'cause it's declared in a class and logically thinking it's type info might be stored somewhere and be retrievable.
In a movie clip, I have several frame labels applied. The type of label is set to Name, which is the default. I want to change some of them to Anchor (to use as named anchors with fscommand), but the Type drop-down list is grayed out. Anyone know why? I can't find any info on named anchors, not even in the Help. Yes I know that anchors don't work everywhere, but this is for a specific client.

-= Lets say I have two swfs: 'parent.swf' and 'child.swf' AND MyCustomObject.as that extends MovieClip-= In child.swf I have a MovieClip physically placed on stage (not using adddChild). Lets call it "ball_mc"-= child.swf gets loaded into parent.swfWhat I want:-= once child.swf is loaded I want to change ball_mc from a ball_mc:MovieClip to all_mc:MyCustomObject-= Then I want to be able to call ball_mc.init() (init() would be a public function in MyCustomObject.as)Why I want to do this:-= I dont want to import MyCustomObject.as directly into the child.swf. This is because there will be LOTS of child.swfs (child1.swf - childN.swf) If the .as is imported directly into each of these AND the MyCustomObject.as changes I have to re-publish ALL the child.swfs so that they publish with the new code... Right.MAIN QUESTIONs:-= whats the best way to go about doing this?? I just want to be able to change the MyCustomObject.as and have the effects show up on all the child.swfs (but not have to re-publish them all

I want to do something like this in Actionscript 3:
if(variable is Object) ...;
else ...;
Where variable could be a String(), Number(), Array(), Object()...Currently the above check returns true for all of these types, which makes sense. I only want it to return true for objects made with new Object(), however.
Is it possible to cast a variable as a type dynamically, where the type would be a variable of type Class? Consider the following (invalid):
var myClass:Class = MyClass;
var myInstance:myClass = new myClass();
For context: I'm working in Flex (4) to create a modal manager that will control various aspects of creating modals (via PopUpManager) and I'd like to keep it as minimal as possible. Components would be passed through the same functions, and rather than allowing any type of variable to be cast, eg:

View 3 Repliesi'm attempting to load data from XML and use this data as variable values. My problem is, loaded XML data is always a String, but sometimes I want to load other variable types.There are several boring solutions to this, such using typeof to determine the the datatype of a variable and then using a function and switch statement to convert the XML data to the appropriate data type. I'd love though if there's a sneaky 1 liner to do this using built in functions. Something like:var x:int = typeof(x)("123");Let me phrase the problem another way.Lets say we have this:
var x:int = new int;
var y:string = "123";
var z: othertype = "123"

ve faced a problem. I have a super class called "Plane" which has subclasses called "Fighter" and "Bomber". each of these subclasses have a bullet type "Cannon" and "Bomb"Now I want the to send a reference of the bullet type to the super class, because bullet creation is handled there and I want to let the super class know which bullet type to create.Ofcourse I could pass a string, I just ant to know if there is a better way, like storing a class type in a variable?
View 2 RepliesI'm trying to find information in how or if it it possible to declare a Variable Type that can accomodate 1 of 2 different Types In this particular case I'd like to set a Variable able to accept either Integrals or Strings I know i Can use a wildcard as below and it works, but it also allows for any other type to be added.
private var _destination:*;
My first Thought was something like this
private var _destination:String^int;
private var _destination:String|int;
Unfortunatly this does not work

View 1 RepliesComing from a Delphi background, I am used to be able to have class references/pointers of a specific superclass, example:
#!pas
var
niceVar: class of TClassOne; // Delphi style
badVar: class; // Only? allowed AS3 style to the best of my knowledge
begin
niceVar := x;
badVar := x;
niceVar.staticMethodSpecificToTClassOne;
TClassOne(badVar).staticMethodSpecificToTClassOne;
end;
What this means is that I don't have to cast my variables to a specific class; they are of the correct Class beforehand. This also means that compile-time checking can be performed to make sure proper members are being accessed and I don't have to check that niceVar is in fact of class TClassOne if niceVar was passed to a method.
[Code] .....
So just like a variable storing an object can be for a specific type and only objects of that class or subclasses of it are accepted, so to does "class of AClass" allow for variables of a specific class to be limited to references to a certain class or those inherited from it. I hope that makes sense somehow; I don't know of specific nomenclature for the whole "class of SuperClass" thing. So I'd like to do the same in AS3 as having variables/properties/parameters of type Class does not cut the mustard; its kind of like having all object variables/properties/parameters simply being Object instead of their proper, specific type.
What I'd like to be able to do
public function set recordClass(aRecordClass: TRecordClass): void {
_recordInstance = new aRecordClass(this); // Compiler will know that I am creating a TRecord
}
How do you declare a variable type that is the same name as the current class in a different package? Is it possible?I'm importing the class and using getDefinitionByName for the instantiation. However, without declaring a variable of that time, the class is not being imported.
