ActionScript 3.0 :: Communicate Between Custom Classes?
Jun 26, 2008
I've started to work with Actionscript 3.0 for a couple of weeks and I've just started my very first "top-to-bottom" AS3 project which I'll be delivering (a "demo") next Monday.However, some basic complications are arising and I just don't know what to do, this probably has been answered a lot of times but I can't seem to find a single blogpost/forum/website that addresses this issue in a way that I can understand instead of "copy/pasting" code.[code]Ok, when I press a button inside the NavBar class I want it to execute a function that tells the DocumentSetup generated MovieClip(contentLoader) to load in a different SWF based on the arguments passed on the Event.My questions are:
1 - How do I access a public function on a different class? Let's say I have my navFunction() placed on the DocumentSetup Class, do I need to create "another" instance of the DocumentSetup Class just to tell it to do something?
2 - Let's say you're able to explain to me how to solve the problem above.How can I reference a MovieClip generated by the DocumentClass through another Class? I need something to tell the contentLoader MovieClip to change contents, how do I communicate with it from another Class if the MovieClip was added to the DisplayList through code on the DocumentClass?
3 - How can I create a Variable which is identified throughout the website, let's say I have an XML file with all the text content that's going to fill in the content placeholder's. How do I make this XML data accessible from all classes instead of having to re-import the XML again and again?
My external classes all work 100% themselves but I cannot get them to communicate with each other, I keep getting compiler errors...A website in which you can't navigate to a different page is basically useless
I've created a base class to house some basic functions I'd like to have across several movie clips in a game I'm making, however, when I link a custom class to the same movie clip I get the message; "The base class will not be used because the class specified is already defined and extends its own subclass. If you wish to use the base class, specify a class name in the Class field that will be auto-generated or enter the default base class 'flash.display.MovieClip' in the Base Class field." I removed the 'extends MovieClip' inside the Class but it still shows the message. Does this mean that I cannot use a custom class and a custom base class on a movie clip?
I'm new to as3 programming and I'm trying to communicate between two classes to get the player coordinates for a game from one class to another class. I tried using a getter and a setter and calling a class public function that returns the value.[code]...
I am still wrapping my head around AS3 classes and how to use them..i want to know how classes can communicate with each other and send information to each other? Below I have created an example of 2 classes inside of a package. When 1 class is finished it triggers the other to start.
I am trying to make a little game. In short words; you control a instance named player, and get attacked by children of the Enemy class.How can all the children of "Enemy" know the coordinates to player instance, how can the document class and the Enemy class exchange variables?
if one can't communicate between mc's external classes how can you create stuff?I have a timer inside each instance form a bomber_mc via a external class:this timer places bom_mc's on the stage from the location of bomber_mc (there are several). But I want to do a do a collisiondetection test with each bom and yet another kanon_mc.can you give me a hint in the right direction?
I've had C# lessons in class and saw some basic class functions. Now however it's been a while since I worked with AS3. And it seems I can't figure out a basic way to communicate through different classes. I'd hoped I could do something like level.backgr1.x += 5; Where backgr1 is a MC defined in the class Level. I'll explain the thing I want to accomplish. I have a 3 classes, Main, Player and Level. Player and Level are children of Main. the mc in Level needs to move when a keyboard event occurs in Player. But only Main can acces Level because it is it parent.
I have 2 different swf files with their own separate document classes. My first SWF file is main.swf and it's document class is called Main.as (its the main container that loads in external swfs). The file being loaded into main.swf is called step1.swf and it's document class is called Step1.as. I have a next button in step1.swf that when clicked needs to tell the document class controlling my main.swf (ie Main.as) to load in the next external swf. However I don't know how to call a function in one document class to from another document class. And I don't know if that fact the swf calling the function being loaded into the other makes this situation more complicated. I've looked around but I cant seem to find the answer anywhere. Basically I need these two separate document classes to communicate between one another.
Here is the code for Main.as (the doc class for the container SWF):

if someone can show me how to get swfNavigation() to run from the other class
For example: how to get public var value in document class from another class in another package.
i know two ways but i need to know what if i am in the right side or not:
1- public static var Root:Main = this; and then call Main.Root.PublicVarName from another class.
2- make instance from the class ( var classInstance:ClassName = new ClassName() ) then to call function or var ... ( classInstance.PublicVarName ) but in this case i can't call the Main ( Document class ) as i got an error when try to create instance from Document class.
I use multiple custom classes like tweenlite, csvparse, papervision and many more. The way I do is put them in one central location and edit Flash CS4 Actionscript 3.0 settings to include that location.The problem I face is even though I don't use all the classes in a project, flash CS4 compiles every single class that is in that central location eventually increasing my compile time by minutes.
Is there any way to get a list of custom classes? I'd like to be able to dynamically access the custom classes (that I've created by the "Export for Actionscript" checkbox in the "Linkage" dialog) without having to hard-code their names into the script.
[code]This is my document class, with the Textfields beeing placed on stage.While this all compiles and displays fine I do not get the trace output for the text fields, actually the only trace I get is "constructing". I tried it without the "each" keyword but to no avail as well.
I'm looking to extend Vector.<T>, but it's final, so I'm going to have to include it as a member instead.Regardless, I'd like to make the wrapper class type independant, so I was wondering what the snytax for template classes are.
i'm still in the process of grasping my move from AS2 to AS3 (or from timeline coding to external classes), and here's a problem i've run into.i have two classes, for the sake of easiness, call them Class1 and Class2.in frame 1, if i have
ActionScript Code: var c1:Class1 = new Class1(); var c2:Class2 = new Class2();
I'm trying to get a button to change color via a Custom class written in ActionScript. I have built and attached an example to show you all what I'm trying to achieve. The code works perfectly with a MovieClip, but when I try to apply it to a Button, it falls flat (can't even find the reference to the button it seems). On my stage are two objects:
1. A Movie Clip 2. A Button
These are both set to "Export for ActionScript", and have an attached class called 'ColorClass'. ColorClass is basically what does all the work (makes a Color object, and has set and get methods). I also have an action layer where all my other code is contained. I'm fairly new to ActionScript, but come from a Java background
im trying to port my code to as3 but i stumbled on a problem i have no idea how to fix. error report:

if anyone has any idea why that error happens please enlighten me
I have a few custom classes stored in AS files. Is it possible to have these classes imported another way from using the following method:
Code: import ClassFile;
I want to have the AS files loaded from a server (policy file created for inter-domain talk) into to flash. Also I want it to work, if a person downloads the main SWF and plays it on their compy,i want the class files to be loaded from [URL] and so on.
I have a an array of a custom class that I'm trying to store in a SharedObject.Storing is working fine, but when I recall the SO next compile it only returns an array of generic Objects instead of my custom class. This only happens with custom classes.Code excerpt below, this may be way too cut out, but it seems it's what I've narrowed the problem down too.[code]
In developing (and learning) some OOP gallery class structures, I seem to hit a snag with the non-blocking nature of AS3.[code]However, I need to get these into a grid, and I have a grid class written that takes an array input. So, ideally I would push the i and v instances into the array, and have the grid class loop through and put them in a neat little block. However, I can't access the width and height of the img and vid class instances. I tried getters, and am thinking of having to do some custom events but I'd rather not. Surely there's something I'm missing?The closest thing I got, but it still triggered late, was an Event.ADDED in the img class.
So this is probably an easy thing I don't know, I'm hoping. But when I publish my project and test it in a normal HTML, the swf can find some classes but not others for some reason?
How can I make sure all the classes get compiled into the Swf? I got the main timeline calling the first class (CalypsoPlayer); and it finds this class find -- which is under the same class path. But CalypsoPlayer can't find the class it needs, even though it's under the same class path as the class.
I've tested the project in Flash itself and it all works great without any errors so I'm not sure what's going on. It's only when I test the published SWF that it can't find all the classes it needs.
I have two custom as3 classes, TriviaGame and TriviaQuestion, and I am attempting to retrieve a bitmap image stored in TriviaQuestion and have found it impossible thus far.
It seems the root of my problem is that bitmap is somehow null in my GetImage() function, even though it is class data that has been set earlier in ImageLoaded(). The only time I am able to access the bitmap's info (in order to add it to the display) is inside ImageLoaded().
In TriviaQuestion.as, loading the image: private function XMLLoadedHandler (e:Event):void { xml = new XML(e.target.data);
I have made a very simple custom class for keeping track of groups of offices for a company. The class has a Number variable to tell it how many different offices there are, and an Array to store the individual offices by name. It looks like this.
class officeCluster{ static var _className:String = "officeCluster"; // variables var numOffices:Number; var locationArray:Array = new Array(); // functions function officeCluster() { trace("officeCluster constructor"); }}
Now, it is my understand that when I create different instances of the class, they will each have their own version of "numOffices" and their own version of "locationArray". When I run traces of "numOffices", this seems to be true. For example, trace(manufacturingOfficeCluster.numOffices); trace(servicesOfficeCluster.numOffices); yields 5 4
In the output panel, which is correct. However, there is trouble with the locationArray. It seems that as I assign different values to it, regardless of what instance I specify, there is only ONE array- NOT one for each instance. In other words, trace(manufacturingOfficeCluster.locationArray[1].theLocation); // theLocation is a String. The locationArray itself holds Objects.trace(servicesOfficeCluster.locationArray[1].theLocation);
Is anyone aware of any issues partaining to using Arrays within Class instances? I've been able to work around this by creating multiple arrays within the class and using a different one for each instance, but this seems very sloppy.
