ActionScript 3.0 :: Cannot Pass Parameter To Already Written Class
Feb 5, 2009
I have written a class that works fine, but as soon as I try make it re-usable and pass a parameter. It gives me this error "1120: Access of undefined property xmlList_0."
Here is ActionScript Code:
package Classes{
import flash.display.*;
import flash.events.*;
import flash.net.*;
public class Carousel extends MovieClip {
[Code] .....
This is the code in my fla.file to run this class:
ActionScript Code:
import Classes.Carousel;
var carousel:Carousel = new Carousel(xmlList_0);
addChild(carousel);
I have seen this code in ultitouch gesture samples. But I don't kno how can I pass a bitmap parameter to the statement [Embed(source="imagenes/prueba.jpg")], how can I use this code with other bitmaps using parameters in this class?
I have an application that gets its variable data in XML file.
This application is used for different clients with different data.
Some of the data I pass to the Document class from the first frame. I would prefer to pass url to the XML file the same way, without the necessity to update the document class. But now I have to hardcode this url in the class every time, because I cannot get parameters from the first frame to the class at once, only after some time (like after loading XML with hardcoded url).
Is there a way to force executing of the code on the first frame before the code in the class will proceed?
I am creating a class to handle some audio in an app I am building. This class will need to accept the XML element path as a passed parameter and or a getter.
examples of some XML elements I would like to pass to the the audio handler class to access them.
Dialog.introScreen.text
or
Dialog.secondScreen.main.text
ect.
I pretty sure this is not a string data type and thus cannot be passed as a string (I could be wrong though), if not, what data type would I pass it as?
I have a class that has a constructor which accepts some parameters. Code: class MyClass { var myNumber:Number; function MyClass(number) { myNumber = number; }} Is there a way I can link this to a movieclip and pass the parameter? From what I've found there are two ways to link the class to a movieclip, one using the registerClass and another typing the name intro the Linkage Box in the Library. But in both cases there are no parameters being setup.
giving a function reference in the result attribute of the HTTPService class like this :
protected function httpserviceCheckUpdate_resultHandler(event:ResultEvent):void { var version:Number = event.result.text.version as Number;[code]....
If both of them are same then how can I provide the event parameter using the second approach (as written in the result attribute of the httpservice class)? Which one of them is the better way of doing things in FLEX.
I have a custom class being constructed from my main class. In the custom class it has another custom class that is passed in as a parameter. I would like to strictly type the parameter variable but when I do, 'the type is not a compile type constant etc'.This, I understand, is because the custom class used as a parameter has not yet been constructed.It all works when I use the variable type ( * ) to type the parameter.I suspect this is a design flaw, in that I am using an incorrect design pattern.It is actually hand-me-down code, having received a large project from someone else who is not entirely familiar with oop concepts and design patterns.
I have considered using a dummy constructor for the parametered class in my main class but the passed in class also takes a custom class (itself with a parametered constructor). I am considering using ... (rest) so that the custom classes' parameters are optional.Is there any other way to control the order of construction of classes? Would the rest variables work?edit)in main.as within the constructor or another function
var parameter1:customclass2; customclass1(parameter1); in customclass1 constructor:
Forgive me for this stupid noob question but I want to call a function (loadList) that originally gets triggered after a mouseevent from another function (addToXML) that does not have an event.
The loadList function takes info from a XML var, sticks it into an array which then gets loaded into a tile list and that is working fine.
The addToXML function when called adds elements to the XML var after which I want to call the first function with the event parameter so it refreshes the items in the tile list.
I know it can do this by creating a new array and loading that into the tile list in the addToXML function, but it be much simpler to just recall the function.
but all the event constants I have tried give me error messges like "1061: Call to a possibly undefined method addEventListener through a reference with static type Function."
I want to use some assets ( buttons, etc. ) I'm creating in flash in a flex actionscript project. Since all my assets are bellow 10K, I'm not planning to load a swf ,wait until it's loaded and create the interface. I want to use a swc and just instance the clips I need. Also, I want my Button class to have some extra properties, and this is where the problem occurs.
If in the Linkage Properties in the Flash IDE I add a reference to a custom Button Class and trace a child of the Button MovieClip, I get the right trace. If then I create a Button, in the Main class in Flex, using the generated swc file and trace the same child of the Button MovieClip, I get null. Why is that ? Is there anyway to get around this ? I've considered using the Flex Component Kit, but since I'm working on a simple actionscript project and I'm not using the Flex framework, I see no point in using the Component Kit at this point.
for (var i:Number=0; i<numFaces;i++){ var faceLoader:Loader = new Loader(); faceLoader.contentLoaderInfo.addEventListener( Event.INIT, function(fle:Event){
[code]....
The problem is that im sending the variable i to the function LoadCara on every iteration, and its always called with the last value of i. I would like this function to be called with the appropiate index.
I have an AIR application that is downloaded from a webpage. In order to download the application, one must be logged in. I would like the first time the user opens the application, to be able to acces the userId that was logged in.
I must be missing something obvious. I'm trying to pass a parameter from a URL into a text field in flash, but it doesn't seem to work. I've got a dynamic text field (display as html is checked), with an instance name txt_txt. Here's the only line of code in the file: txt_txt.htmlText="test "+this.loaderInfo.parameters.nameVar; And, when I upload it and use the following, I get "test undefined" as my return!? [URL]
I´d like to know how could use the Timer class extended.I´m trying to pass a parameter to the constructor function, so I can use it inside the listener.
Here´s example:
[CODE] package { import flash.utils.Timer import flash.display.DisplayObject public class ChangeColorTimer extends Timer { public static const CHANGE_COLOR:String = "changeColor"; public var obj:DisplayObject public function ChangeColorTimer(delay:Number, repeatCount:int, obj:DisplayObject ) { super(delay, repeatCount) this.obj = obj } } } [/CODE]
That was the ChangeColorTimer that extends Timer.Now, I´d want to know how would I use ChangeColorTimer.I thought it was the same as using Timer.I´ve tried this:
[CODE] public function changeColor(mc:MovieClip):void { var colorTransform:ColorTransform = new ColorTransform() colorTransform.color = 0xEE0000 mc.transform.colorTransform = colorTransform var changeColorTimer:ChangeColorTimer = new ChangeColorTimer(400, 1, mc) changeColorTimer.addEventListener(ChangeColorTimer.CHANGE_COLOR, setNormalColorListener) changeColorTimer.start() } private function setNormalColorListener(e:Event):void{ trace("called") } [/CODE]
I called changeColor, but, I don´t get "called" in the output from the setNormalColorListener listener.
i want to pass by reference so i can use this variable outside the function.
What im doing is creating a global variable such as var cont:int; and then in a eventListener like enter_frame (stage.addEventListener..) calling a function called "mover", this function modifies "cont" value and i just want to print this value modified. The issue is i cant pass the value by reference just by const :S. The function is void, but if i change it to return int, its useless because each time i call the function, the value i want to return its created each time with a new value, beacuse i need to declare it so.. I read i can use a var such as Object but i really dont get it (im used to c++ i have to say)
