What is the scope of a class created in Flash? If you create a class on the main timeline, can you use it anywhere in your project? If you use your class in a a movieclip, can you use that class outside of the movie clip?
View 3 RepliesI was reading tonypa's tile based game tutorial and tried to translate it to as2 when I realized two things:a. I don't know/remember what the this[stuff]._property syntax means, I don't recall seeing [] except in arrays. can someone explain/link to an explanation/name to so I'll know what to look up.b. I don't know how to scoop my individual tiles. my code is the following:

I add this actionscript code on the first frame. Variables are loaded but. The question is below the code.

Normally when creating small apps, i create a small object something like this.
Code:
//Example
var theApp:Function = function(){
[code].....
Take a look at this code:
Code:
import mx.utils.Delegate;
class Test
{
[code]....
Well... Doesnt work at all... In the class, there isnt a instance of i, so, how may i access this property inside a class function? But i still have an way to access the class.
I could do this way:
Code:
class Test
{
function Test(mc:MovieClip)
{
[code]....
But this way, doesn't sounds good
I have this extremely odd problem. OK to start off I have an MC in my library with the linkage identifier "Interface" and the AS2 class "Player" (both without "" of course). Now, my player class looks like this.

I have a Debug class I've written, and I'd like to include a static trace() method in there, unfortunately I have no idea how to then access global / top level trace as effectively I've blocked it with the local static scope.[code]
View 4 RepliesI recently completed a tic-tac-toe game in AS3, using some simple function-based code I had written in C many years ago.Now I'm on a quest to do it the "right way" using OOP techniques and best practices.Everything is now divided into neat little packages, it looks pretty, and the last part of my journey is to get all the little buggers to communicate with each other.I want to move the code which holds the game state from my main to it's own class in com.okaygraphics.model.GameState.The problem is nearly every other package gets and sets these game state properties.I'm trying to figure out the simplest way to encapsulate this stuff, while still allowing my other classes to access it.
1) Do I need a constructor? I mean, my program will never have more than one GameState. If I should call my getters/setters as instance methods, how do I get each other class to reference the SAME instance from their respective packages?
2) Do I even need getters and setters? Perhaps the class could just have 3 public properties? If so, how would I acheive the proper scope with regard to my other classes?
3) Should I assign everything to the class itself using the static keyword? If so, how would I implement and use those static methods?
4) Is this a mistake? Did I totally just program myself into a corner?

Specifies the value of thisObject to be used within any function that ActionScript calls. This method also specifies the parameters to be passed to any called function. Because apply() is a method of the Function class, it is also a method of every Function object in ActionScript. i don't get how "thisObject" is accessible from within the function invoked with it's apply method i'm trying to pass the scope of one class to the function of another so that the keyword "this" in the target function refers to the passed scope or am i misunderstanding the apply() method? it appears to behave differently between as2.0 and as3.0 as well, try this example code from the adobe docs

I have 2 class. Main class and a subclass (being an image loader).When the subclass has finished loading I want it to access a timer function in the mainclass.Code: Select all1)mainclass |> subClass.loadMe();2) When subclass load finished.3)Subclass |> mainclass.startTimer();This i dont know how to do.
View 2 RepliesHow do I fix this? With this code in my class:
function moveDelay():Void {
myInterval = setInterval(this.movePoints, delay);
}
I lose scope when it calls the function. "this" becomes undefined.
I have 3 files.
main.fla
PHP Code:
import classes.LevelObj;
var newLevel:LevelObj = new LevelObj();
var levelListener:Object = new Object();
levelListener.onLoaded = function(oEvent:Object) {
[Code] .....
Now this runs great but in the loadLevel function of LevelObj.as, when I receive the event from the GBXML class that it has finished loading I want to call another function within the same class (LevelObj) to continue with further processing the XML data. What I make of it, is that I am still within the scope of the myListener object. Should I use a Delegate function here to get to the function within the LevelObj scope?And how about properties from the LevelObj scope? When doing a simple trace of some testVar I get undefined. Logical ofcourse because it is not within the same scope. But I am stuck here.
This is the part that should contain the call to the function..
PHP Code:
myListener.onLoaded = function(oEvent:Object):Void {
trace("LevelObj.XObj > "+oEvent.success);
if (oEvent.success) {
trace(testVar); //CALL FUNCTION HERE IN SCOPE OF LevelObj
} else {
public function addNewMc():void{
var newMC:MovieClip= new MovieClip();
this.addChild(newMC);
}
public function removeOldMc(newMC):void{
this.removeChild(newMC);
}
How can I create a new MovieClip within a method, which can be used throughout the class, without defining it at the top of the class? And for extra points, without using return. I can get it to work, if the first function addNewMc returns the value newMC, and passing that to any other methods.
I'm not an experienced Actionscript user so I'm not sure what the normal way to associate a custom class with a movieclip that has been designed in the Flash IDE is. I made a class called Window to control a movieclip called TestWindow. There are some buttons in the movieclip whose
functionality I would like to assign the instance of class Window. How is this supposed to be done? Here's a representation of what I mean. I hope it is sort of clear. My actual problem is that the local variables are outside the scope of the onPress function but I also think there must be some other way of associating classes with movieclips that have been designed in the IDE.
My question deals directly with ActionScript 3, although it could possibly appear in other languages. Consider the global trace function found in AS3. Calling the method requires no imports and is globally available from all classes.
class A {
public function A() {
trace("Hello, A!"); // Hello, A!
}}
Now, what if I create my own class method of the same name? In AS3, if I have a class method trace and then make a call to trace elsewhere in my class, the call is made to the class method over the global function. Essentially, I've blocked my ability to call the global trace method.
class B {
public function B() {
trace("Hello, B!"); // no output
} public function trace(s:String):void {
// do something else.
}}
Now, I know the obvious answer is to say, "don't create a class method called trace." But what if I'm unaware of the existence of the global trace function? Or what if I have a desire to "override" or "block" the global function? Is doing so bad programming? Or is this just another example of how AS3 is a poor object oriented language?
I have an object and would like to call a function from it, which the way I am trying to do it, does not seem to work. Here is what I have:
Code:
private function setTimer():Void
{

Why I am losing scope on an array that i define as a private member in a class? I am able to access it from a couple of different functions but in one place inparticular it keeps coming up "undefined". What causes scope to be lost in a function for an array that is defined as a private class member?
View 4 RepliesI have some class that I created visually in Flash Professional CS5 by transferring drawn result into a MovieClip and extorting symbol into AS code. Now, I want to add some properties to the class. To be more specific, I've created Ball class and want to add to it variables that will represent vertical and horizontal speeds. How can I edit the class in order to do it? Also, when I wanted to add some visible external element to the class, at first I decided to add MovieClip property in the code itself, but then recalled method .addChild() that worked perfectly for me. Now, I can't do the same with non-visible properties. So, what is the difference between adding visible elements using .addChild() and adding them in the code itself?

Is there anyway of resizing a swf after its been created in flash?
EXAMPLE:
My document size of my animation is 520px width by 680px height... when i resize this as an embedded swf in an html page (through source coding) to 382px width by 400px height.. the animation does not flow properly and there are occasional jerks... its not fluid.
Is there an easy way to do this in flash after its been created? Or am i going to have to start from scratch with the proper document size?
I've followed several instructions on how to develop a simple iOS app. I've managed to go all the way through and Publish + create the .ipa. I'm able to then add the file to my iTunes library, but when I then try to add it to my iPod Touch (2nd Generation) I get the following error:
The app "XXXXXX" was not installed on the iPod "XXXXX's Ipod" because it is not compatible with this iPod.I've even tried it with a simple "Hello World!" app but I get the same error.I'm using Flash Pro Cs5.5 on a Windows PC.
I published a Flash movie in CS4, which includes the following ActionScript 3.0 code to allow people to click the movie to open a new web page; but it will not play from the web server...however, it plays just fine from my local hard drive in Firefox and IE 7.It is an html file with an embedded .swf and I made sure to copy over the swfObject.js, AC_ActvieX.js, AC_RunActiveContent.js, expressInstall.swf, and swfobject_modified.js files to the correct directories. The address is: [URL] and as you will see, there are no errors...just a blank page. I even tried changing the script from:
<script type="text/javascript"><!--swfobject.registerObject("FlashID");//--></script>
to this script: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>, but using this script generates a lot of CSS and other errors.
Nothing works. The ActionScript code I used is:
//Link to websiteSite_btn.addEventListener(MouseEvent.CLICK,visitSite);
function visitSite(e:MouseEvent):void{ var req:URLRequest = new URLRequest("http://giseldemarco.com/Home/Index.html"); navigateToURL(req,"_parent");}
I urgently need to be able to check the authenticity of a Flash CS4 file. There is no information given about author etc in the properties using Windows but I was hoping that Flash embeds author information and history.
View 1 RepliesThis seems like it should be MUCH simpler than it is turning out to be: I have made a custom template in Flash CS4. I want to share it with a colleague. The obvious solution, I would think, would be to COPY the template file from my hard drive, and provide it to my colleague.
However, I have looked high and low, and CANNOT FIND WHERE USER TEMPLATES ARE STORED on my hard drive. I have found the Adobe-provided templates that are included with the product (the "Advertising" templates) at Program Files>Adobe>Adobe Flash CS4>en>Configuration>Templates>Advertising; but MY CUSTOM TEMPLATES are not in the Templates directory.
I have also looked in My Documents, and run several searches on my hard drive, but still cannot find the location of my custom templates. Surely they are SOMEPLACE on my hard drive, as they are available from the Splash page every time I boot up Flash CS4.
there are many flash with obviously too complicated video effects thsat impossible to create in Flash itself even with most advanced actionscript. I purchased couple of samples and it turns out its just sequence of images from the video i guess. So my question what video programs are used to create this and what effects packs are availible for flash or that video programs i rather buy stack than pay per each.

View 1 RepliesI'm trying to use 9-slice to animate a natively created flash movieclip. It's a rounded-corner box, with a little speech-bubble pointy thing jutting out of the bottom left corner. I have 9-slice enabled, and the slices have been repositioned close to the corners. When I distort/grow the MC on the flash stage, it's fine... but as soon as I try to animate the growth, it gets all wonky?
If I use the newer Motion tween style, it's messed up all the way through except for the first frame? And if I use a traditional tween, with the proper small box start frame, and modified/grown end frame... it will look right for the first and last frame of the animation, but its as if the 9-slice isn't working during the tween? I've inserted a series of screen caps to illustrate the traditional tween issue.
I have only one question but phrased it 3 ways:
1) Is it better to pre=render things say in photoshop or have flash render them?
2) if I have a field of stars that drift along; is it better to create that Star Field in photoshop as a single picture (say a .png) or to create a star in my library and add it to a movie clip and then have that drift along?
Lets say I have a blur effect on my stars and have an equivalent on the photoshop.
3) I have heard (and experienced) adding effects like blur takes a fair amount of CPU and memory so was wondering if I created the effect in photoshop and then imported the 'blurred' object into my flash if I could cut down on system resources?
I have this Fla which contains a symbol that is linkaged to a certain class that is in my project. That class inherites a base class named CMovieClip which resides in one of the libraries that is in the class path (and inherites from MovieClip).Of some reason, every change that I do in the base class doesn't seem to influence the resulting linkaged class, much as if this library is cached somewhere that I can't feagure out.I tried to create the same conditions in a separate Fla but it does not repeat the issue.I tried to duplicate the symbol but the issue isn't solved that way.
