ActionScript 2.0 :: [OOP] Calling A Method In A Method?
Jul 24, 2006
Code:
class A{
function A(){
trace("construct");
}
private function moo(){
[code]....
yet this doesn't, I'd expect it to: construct, start mooing, moo!, moo!, moo!, ...yet the moo! moo! moo! doesn't appear, as if moo() never gets called it all.
getUser was already in UserService.java. I just created getUser2 and it's identical to getUser. When I try to call getUser2, i get the "Cannot invoke method" error. question: Do I need to specify getUser2 in some other file? like in some configuration file? if so, which one and how do I do it.
I have two classes, in one (the Start class) I want to run a function I created in another (the Brown class). I commented in Start where I want to call the "addBrownListen" method. I tried doing it with the line: Brown.addBrownListen(); But that didnt work.
Here are the two classes: package { import flash.display.MovieClip; import flash.events.Event; public class Brown extends Rebounders { [Code] ......
Suppose that I have the following inheritance scheme: Foo -> Base1 -> Base0 (i.e. Foo is indirect successor of Base0). Base0" that has method "bar()" and class "Base1" overrides method "bar()". Now when overriding method bar in Foo I want to call method bar() that belongs to the Base0 class.
Making a flash video streaming web-app using Actionscript 3's external Api. I am at a very rudimentary phase of the project where we're just experimenting with external interface. Right now i just have a flash object and 3 buttons each to play pause and load a video. The only button that is currently set up to do anything is the load button. My swf and my html file sit on the same file system, and my video files sit on another server with traffic being redirected through a media server.When i press the load button, which should just give it the path of the video file on it's server. Instead it throws an error that reads "Error: Error Calling method on NPObject". [code]I've read in a lot of places that this is an issue with security, but both my swf and html are in the same folder on my local machine. Only the files come from outside, and in any case I think i've set the security settings correctly when i declare my flash player in the object tag, but maybe i'm missing something there.if you can't solve my question directly can someone please explain what "error calling method on NPObject" means? I'm sure its specific to flash-js communications because i've never seen it before and that's what i have gathered from my googling.
If I have a MovieClip, simply a blue square with class AS file called blueBox, in the constructor of the blueBox.as file I have: this.addEventListener(MouseEvent.MOUSE_DOWN, sayHello); Why does this not call the sayHello method when I click the movieclip on the stage? I know on the stage that I could grab the instance of my bluesquare movieclip and add an event listener to it that way, but I just wanted to 'encapsulate' in a bit more.
I created a new class as DraggableObject in Flash CS5 with the following definition:
package { import flash.display.MovieClip; public class DraggableObject extends MovieClip{ public function DraggableObject(){
[Code].....
Before running the code, I had a simple rectangle object converted to a movie clip and exported it to actionscript with the class of 'DraggableObject'. I just had it in library (i. e. no other instance in the stage). What I wanted is to create an instant of it at run-time ( 'draggableObject' ) and have it added to the display list of the stage, throgh its method 'draggableObject.addToStage()'.
And I don't have an idea as to what 'null object' referes to here. Since I created an instance in the line "var draggableObjectraggableObject = new DraggableObject()", it cann not be null....? When I commented out the line 'stage.addChild( this );' in the class definition (line9) it works with the trace statement output.
If all I have is an instance of an object, can I call a static method of its class? For fun, let's say I don't know what the name of the class is, only the name of the static method.
I created an application to show a datagrid with a custom column in Flex 3. How can I access the method loadDetails in this code?:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ public function loadDetails(id:String) : void { // Some code here
[Code].....
When I tried to run this code Flex throws an error. It says that loadDetails is not defined. I suppose that error is because of scope.
I have a WCF web service (using basicHTTPBinding) which I am connecting to from a Flex application. I am using the FlexBuilder code generation to make a proxy for the web service.This has been working great until I tried to call a method on the web service that has no parameters. Here is it's interface declaration:
I then started getting HTTP 500 code responses from the service.Inspecting the HTTP response with Fiddler shows that WCF is reporting the following error:
Error in deserializing body of request message for operation 'GetCurrentDateTime'. The OperationFormatter could not deserialize any information from the Message because the Message is empty (IsEmpty = true)
So it seems that there is an incompatability between Flex and WCF whan calling methods that have no paramaters - Flex doesn't include anything in the message but WCF is expecting something to be there.Is there any way to configure either Flex or WCF to work around this or am I going to have to include dummy parameters in such operation contracts?
I have a simple flash socket that I use to connect to IRC servers. It has an open, close, and send method made available to JS through ExternalInterface, for opening connections, closing connections, and sending messages respectively. The socket calls IRC.io.receive in JS whenever it gets a message, which is parsed by JS into something useful.Unfortunately, whenever any of the flash methods are called from JS, they return a "__ is not a function" error.Here's the (watered down) AS, where IRC is the document class:
public class IRC extends MovieClip { public static function open(url:String, port:int) {/* code */} public static function close(port:int) {/* code */} public static function send(port:int, message:String) {/* code */}
[code]....
Any call to any of the functions registered with ExternalInterface throws a "function does not exist" exception.
My method has been passed a class instance, but it was typed through an interface so I'm not 100% sure what class it is. I'd like to attempt call a static method on that instance's Class.. is there an easy way to do this without being forced to pass the class along as well?
Something like this:
ActionScript Code: public function foo(myBarInstance:IBar):void { var barClassPointer:Class = getClass(myBarInstance); try {
I am using the below package to play back a wav file. In my main file I create several of these objects, put them in an array, and then try to call playBack().
Unfortunately it doesn't work. However, I can call playBack() from within the object, for example by having this object create a button.
I have my game swf called inside a fla with loader method. The swf loaded completely, played well.Strange,when my player lost game, I mean for GameOver dialog box. It was playing well without any fault when i played my game swf individually, but when I called it inside a fla, its dialog box button is not working as usual.
It's early days in my AS3 learning, and I'm looking for a little clarification regarding a variable typed to a superclass (in this case var mySpinner:MovieClip) which contains a reference to an new instance of a subclass (in this case Spinner.) I am trying to get my head around why my code compiles and runs and I am able to call the method rotater() on mySpinner even though mySpinner is typed as MovieClip, and the MovieClip class does not contain the method rotater().
On page 163 of the official Adobe Programming ActionScript 3.0 documentation it says the following, which I believe is related to my situation, but I am still in need of clarification: "Because each class defines a data type, the use of inheritance creates a special relationship between a base class and a class that extends it. A subclass is guaranteed to possess all the properties of its base class, which means that an instance of a subclass can always be substituted for an instance of the base class."
I've been playing with the visualization API aka dynamic charts and I've found that the example at [URL] does not really work on localhost. That is, Error calling method on NPObject is thrown when a event is clicked (points A and B in the example aforementioned). I suppose that is a security issue on the server end (Google's flash base).Since that jsFiddle code is hosted on a domain, the note at the very bottom of the documentation should not apply:Because of Flash security settings, this (and all Flash-based visualizations) might not work correctly when accessed from a file location in the browser [URL] rather than from a web server URL [URL] .
I've always just developed my projects in as3 instead of mxml and I usually just setup my application to run a main actionscript file as my main doc root, sort of like how you do it in flash but in flash builder I do something like this:[code] how can I call place a call to that function hitme() within the call_from_outside() function between the <fx:Script> tags?The reason why I'm doing this is because I have some flash swfs that I load into another swf file and I can access the top level public functions of those flash swfs, however the top level of the flash builder/flex swfs is the main mxml file not my fake as3 class root. Of course I should think there is a way for me to access the as3 class methods of the mxml component but for keeping things with the same structure, I can bypass having to modify my loader scripts.
I am trying to call a method that has some xml functionality and It keeps coming up null.What I am trying to do is; I have a page that has four dynamic text fields that get their content from an xml file. I would like to create a method that will output the contents to display in the dynamic field. Maybe my approach is WAY off here, but my supervisor wants all xml related tasks contained in a xml.as fileMain.as
TypeError: Error #1009: Cannot access a property or method of a null object reference. the main idea is calling a method from subclass that inherit to a superclass.. here is the code
Is it possible to call a function defined in a movie clip from a class?Here's a sample project setup I'm trying to achieve this simple feat:
func.fla - Has one movieclip "fooinst" which is library item "foo". - The "foo" library item has linkage is to the "Foo" class - The "foo" library item has one script on it's first frame:
I'm using the "loadMovie" method and according to the using flash manual.. it's supposed to import a swf and resize it to the size of the movieclip it's replacing... only here's the problem.. I cant get it to shrink the incoming swf to the size of the clip calling the method... it keeps importing the swf at full size..
I'm tryng to make a public static method call another method, but Flash throws error 1180, sayng that the method called by the static method is undefined.
