I am lesrning actionscript. I am trying to call an instance method called "resizeSection". But I get the error "access of undefined property _header".
Below is the class where I'm calling the function.
package {
import flash.display.*;

What I want to be able to do:
- click a guy to select him
- click an adjacent tile
- move selected guy to clicked tile
The way I've coded it, each instance of a guy class has a mouse even listener on him which listens for a click. When clicked, I find out the tile underneath him, and the surrounding tiles. So far, so good.
When clicked, the guy calls a method in the tile class, like tile.onClick, which tries to say: get this tile, and send it back to a method in the guy class, like moveGuy. Then moveGuy moves the guy to the tile it was told.
Problem:
From the guy class, I call a method in the tile class. To communicate between classes, the tile class method onClick must be static. But if it's static, the method can't refer to "this", because it's a method in the class only, not on each instance of tile. But I need to know which tile was clicked, and send that reference to the guy so he knows where to go.
How do you access a method from outside its class so that the method can refer to "this" instance? OR, how do I find out which tile was clicked without needing any code on each tile instance? OR... how else can this problem be solved?

Is this problem what getters & setters are for? I don't really understand how to use them yet.
I have a custom function that doesn't function correctly the first time the function executes it removes a textFiled from the display list without a problem but the second time that it executes it won't remove a diffrent textfield and I don't know why here is the code from the time the textField is added to the diplay list to where its deleted.Btw the function in question is being executed by a custom event listener.....the errors i receive are TypeError: Error #1009: Cannot access a property or method of a null object reference...Also note that i can remove the textField in question from any function other thatn the one the custom event executes.
PHP Code:
sendBtn.addEventListener(MouseEvent.CLICK, sendMsg0,false,0,true);
msgOut.addEventListener(KeyboardEvent.KEY_DOWN, sendMsg1,false,0,true);
comboBox.addEventListener(Event.CHANGE,chFontSize,false,0,true);[code]..........
two classes, both extend EventDispatcher. Static method in 1st class calls instance method in 2nd event not getting caught. [code]also, since dispatchEvent() is an instance method, is there any way of calling it without first instantiating the class? i expect not.

I want to have a custom class tempSelection with a Dictionary as a public accessable property of that class. If I use this code, the compiler tells me:

Which translates to:

I created a class of sliders that are used to control the opacity of various movieclips. The movieclips are layered on top of eachother, so if one slider is at 100%, you can't see the other movieclips below it.
Is it possible to push one slider (e.g., 'sliderBus') down to 0% when a new slider (e.g., sliderAir) is moved above 0%? Basically, I only want 1 slider to be able to be above 0% at any given time.
.fla code:
Code:
var thumbAir:img02 = new img02();
thumbAir.x = 450;
thumbAir.y = 773;

I have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
From my Main class, in the method onBackgrLoad, I am trying to call a couple of public methods (i.e. xmlData, hintergrund & numOfProducts) located in LoadXML. I keep receiving an error message that "loadXML" is undefined. I dont understand why because I clearly defined it in the main class:

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'm getting into actionscript3 and was wondering if there was a way to make an 'onclick' type function that returns an id or an instance name. For example in jQuery you can do the following, which is great for then passing the id into an array or whatever you choose.
$('.menuButton').click(function(){
var collectedID = $(this).attr('id');
Is there an equivalent to this in AS3? I'm assuming grabbing the instance name would be the goal? I haven't run across ids in Flash yet.
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);

I have a button which is an instance of a "button1" class. The button is instantiated by an instance of the"introScreen" class which is instantiated by the "screenHandler"class. I'm not sure how to attack getting an instance(the "button1" instance ) to dispatch an event heard by its grand parent(the "screenHandler"instance). My main confusion is getting an instance to transmit a specific event like the name of the screen to switch to. Can I specify a custom event in an instance?

How can I do that? Or I need to extends the Image class?
Through searching the various forums I have found that Loaders are not dynamic and hence you can not apply custom properties to each instance of them. I miss the old way (as2 way of attachingMovieClip) that you load dynamic content, at least you can apply custom properties, and you can always reference them for each object.What I'm trying to do is load a group of Images via XML. Each one of those images have a set of information that is associated with them (name, description, etc). I have the images loading in and positioning just fine, however when trying to have a tooltip show the name on Mouse Over, I'm not able to achieve this.
In short. I want to be able to store information for each item so that I can access it. Is there a way to do this in AS3 with a Loader or is there another route I can go? If I do this with Arrays, how do I store the Index of the specific item so I can use that in reference to the position in each array?** Should I use getChildIndex() in the function for the Event Listener to reference the data stored in the arrays for each item? If so, how do I do so? ***
PHP Code:
num = 0;var titleArray:new Array();function createImage(){ var thumb:Loader = new Loader; thumb.load(new URLRequest(url);

I have written a piece of code where I have created a custom class containing some of my custom properties.I have used multiple instances of this custom class in my main class and added it to a container.Now I need to access one of my custom property in the main class through container.getChildByName()."custom property", but I am not able to access my custom property using this.I get an error saying
Access of possibly undefined property orientation(this is my custom property) through a reference with static type ..name of my main class.
Is there no way that can i access custom property of components through the getchildbyname method of the parent container ??
I have this sample class
Code:
class TestPrivate{
public function TestPrivate(){};
private function getGo(){
trace("can execute");
}}
And then after instantiate I just calling the method...for testing the "public" and "private" keyword purposing only...
Code:
import TestPrivate;
var obj1 = new TestPrivate();
obj1.getGo();
The result is still can be execute even though I put the private keyword in front of the methods. So what's the private keyword stands for actually...I thought it prevent been get accessed from outside...
