This is for a playbook app. I have two classes:
public dynamic class Bullet extends Sprite {
public function update():void {
x += 5;
y += 5;
[Code]...
This is essentially what I'm trying to do. What's the best way to achieve this in actionscript?
override a custom class method with a function expression? For instance, if I want to change the destination of a button on the fly, I could theoretically type:
Code:
var new_destination:Function = function(evt:Event):void{ go_to_new_place();};
myButtonClass.mouse_clicked = new_destination;
but unfortunately that generates an error because the class method "mouse_clicked" is already defined in my class (with the eventListener tied to it). I tried using the "override" keyword in the Function Expression but that didn't work either.
Ive been trying to write my first Blackberry Adobe Flex application but get the following errors:
1172: Definition mx.controls:Label could not be found.
I'm creating a pure actionscript 3 mobile project for Blackberry Playbook. One problem I have came across is that there seems to be no inbuilt way to handle view navigation. In flex mobile projects, we have the spark.components.ViewNavigator component, but this isn't available on a pure AS3 mobile project. These two links are both making their own libraries for view navigation...

I am creating a Playbook app in Adobe Flex/AIR. I have a situation where there is too much content to show all on one page so I would like it where the content overflows vertically, the user can swipe to scroll down, like they were viewing a website on an Ipad.
I am extending the View class to make my screens, I could place every screen in a one element List or surround it all in a Scroller but surely there must be an inbuilt way to do this on the Playbook?
With the limited Blackberry documentation, I'm struggling to find the solution,
Is possible to make a "push", initiated by a server, to send data down to a Blackberry playbook application?
If so how is this best implemented in Flex/Actionscript? ie. How do we capture this on the client?
I have a Flash application written in ActionScript 2 that I would like to port to the BlackBerry Playbook. The application is composed of an .swf file and a directory containing a large number of vector images. The path to these images (e.g. imagefolder/icons/icon1.swf) is hard-coded into an application and requires the image directory and the .swf file to be in the same directory.
I've installed the PlayBook SDK and have tried packaging the application with FlashBuilder 4, but I have no experience with this programme and have so far been unsuccessful. I tried placing the application in an SWFLoader component, but I then realised after reading this pdf document that MXML components are not supported. Since the app is written in AS2, I believe it cannot be compiled by Flash Builder. I don't need any any of the AIR features so I was wondering how could I embed the .swf and image directory in a Flash Builder ActionScript project so that it would run on the BlackBerry PlayBook.
way to modify/replace the icon of a Playbook program?
Like display a red star on it - to indicate there is new message for the user.
I've tried tracing NativeApplication.supportsDockIcon and NativeApplication.supportsSystemTrayIcon properties, but they are both false on Playbook simulator.
What is a good framework to build a multiplayer game in Actionscript? I want to create a multiplayer 2D shooter like Asteroids on the Blackberry Playbook; my main concern is latency - a shooter wouldn't be fun if the bullets are super-jerky and unexpectedly hit people. I'm guessing that a UDP-based framework would be the best.
View 4 RepliesI'm trying to do an unzip like application for the Blackberry Playbook, which means that the application mostly gets launched when the user clicks a file for which the app is registered.I googled a bit around, and the closed what I found is this, but MobileApplication doesn't have invoke parameter.

there is a Picker example for usage in an ActionScript project. It works well in simulator. But how do you use that component in a Mobile Flex Project (with Burrito Flash Builder)? How do you add a qnx.ui.picker.Picker to a spark.components.View? The latter seems to expect a mx.core.UIComponent, but the former is a qnx.ui.core.UIComponent. The ActionScript project I've mentioned above works ok, because the Picker is added to the Sprite. But adding it to a View in a Mobile Flex project fails for me.
UPDATE: I've found this page today: [URL] And also I've found out that the QNX AIR components work on Android as well, wonder if it is legal to use them there? Nothing is mentioned in Playbook SDK Legal Notice.
I have learned that there is a class called Function which is used as a blueprint for all as3 functions. Is there a way to override the call() function within the function class so that a trace can be made when any/every function is called?
View 2 RepliesI have two child classes ClassA and ClassB both inherit the same base class.
I also have a function that has a parameter which could be an instance of either child classes.
function Test(instance):void //instance is either a ClassA or ClassB instance
{
instance.DoSomething();
}
However, when I run the test, it's always the BaseClass.DoSomething() get called. How can I use the same function (DoSomething()), but call child class function instead of the base class one?
Is it possible to externally override a public function of a class (as opposed to override via inheritance)?
For example:
Code:
Class Foo {public function doFoo():void {trace ("Foo");
}
}
Such that:

I know this is possible in JavaScript and ECMAScript, but the compiler won't let me get away with this kind of mischief in ActionScript, from what I've seen: It barfs up a 1168 Illegal Assignment error as soon as I attempt to assign a new function to doFoo.
I'm thinking specifically in terms of a "hot fix" solution where you deploy a small swf that replaces a specific chunk of code in a larger application, without the need to recompile/deploy the full application (or even see the sourcecode for that matter, just know the API).
i know its easy to override a function of a parent class, but I need to be able to override a function for a class on movieclip.. see highlighted code.

I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

is there a way to extend a function, or override it, without having to rewrite the whole function. e.g would it be possible to add a simple trace statement at the beginning/end of the addChild() function. im looking for something similar to super() in constructor. just as i dont have to rewrite the whole constructor of the class that i extend, but i can add my own code, then call super(). ive read something about prototypes and that they could be possible solutions.

I trying here to avoid having to bind resources to all my components labels ( ie a button) and find a way to have this automated.
Problem: It corrupts the layout in design mode to bind directly in the mxml label="{resourceManager.getString('myResources', 'submit')}" and makes the design view useless. but when declaring bindings elsewhere, in actionScript or via a bind tag, it is counter productive and prone to many errors and miss.
Proposition: I would like to create my own button that automatically invoke resources to localize a button label. So the author puts "Submit" in the mxml description of my button, and when running it would take the value of the label ie "submit" and use resourceManager.getString('myResources', 'submit').
but I can't find the way to override the set label function, Is it possible if yes how? else how can I go about it?
Maybe I am missing an essential process here that would make the use of resources more elegant, as well as how to override such thing as a button's label.

View 2 RepliesThe current implementation of the Flash Player ApplicationDomain with regards to override class definition seems like a giant security flaw to me.A parent SWF has complete control over what child SWF they want to load and add to its ApplicationDomain. It stands to reason that if the parent trust the child SWF enough to load the file, it should also trust the class definition defined by the child SWF and use those definitions.
In contrast, a child SWF has no control over where it is being loaded into, or if it want to be loaded into another SWF at all. Therefore, there is no reason for the child SWF to trust the class definitions defined by the parent SWF.I recommend changing the current implementation of the ApplicationDomain and allowing a child SWF to override any conflicting class definition in the parent's ApplicationDomain.

View 1 RepliesI'm having a total brain fart right now because I haven't dealt with AS2 library linkage classes in a while. I want to be able to let a designer assign an object in the library to a specific class and have that class listen for changed _x and _y values.I have the class made up that extends MovieClip:
Code:
class CoordinateMonitor extends MovieClip {
public function CoordinateMonitor () {}
}
But I draw a blank now on how I'm to monitor _x and _y values for the clip. I'm pretty sure I remember it being possible to do this and declaring an overriding function ("public function set _x(val:Number) { super._x = val; }") does not work as intended.
