I am defining this function in one of my classes:public function onUse():void {};Then in another of my classes (let's call it "class2"), I create a object of this class, and then want to override this function with another one. After some Google-Fu, I have found this, and used it...
button.onUse {
variable = value;
}

View 7 RepliesI would like to make a little app to test out the Accelerometer class. I was thinking of using a Loader to load the swf, and replacing the Accelerometer with my own copy. Is there any way to do this? If it's not possible, how could I do this with a custom client?
View 1 RepliesI'm overriding a protected function in a subclass.Let's say I have two classes, Apple and Fruit. I have all variables in place, this is just a simplified version.
[Code]...
Example is trivial. The problem is that the type of the getRandom function depends on its own type. One returns an apple, the other returns a fruit.Of course I get errors about override and coercion.
I've tried returning a Fruit instead of an Apple, but then the object is not an apple, therefore it has no Apple-specific properties.The problem is in ducktyping. There's a third class I cannot change, that executes the getRandom() function on each object, and I need the Apples to be something slightly different.
How can I override the getRandom function in Apple, so that it returns apples, rather than fruit?
I have a .fla and one.as(DisablingButtons.as).The .fla currently has only one key frame and three movie clips.First movie clip has base class flash.display.MovieClip and class DisablingButtons.as.The other two movie clips have base class DisablingButtons and their own classes (set by flash on export). The movie clips have identical timelines, 20 frames, two motion tweens, and the only action is stop();on frames 1,5,10,15. I get two errors:5000: The class 'DisablingButtons' must subclass 'flash.display.MovieClip'and 4 copies of 1024: Overriding a function that is not marked for override (on frames 1,5,10,15 of movie clip #2)

I'm using FlashBuilder 4 beta2. My base class has a function foo():
protected function foo(s:String, z:String=null): void{}
Literally "foo" so that there's no chance I'm stepping on a built-in method. I am getting an
"Incompatible override" error when attempting to override the method in a subclass:
override protected function foo(s:String, z:String=null): void{}
Does the optional parameter do something "behind the scenes" that makes it illegal to override the method?

View 2 RepliesI am working on a Flash demo (all AS3) that requires a scrollbar. I wanted to create my own so on searching I found this Kirupa tutorial. I learned it an incorporated everything (also went well beyond) and the end product works nicely. There is one aspect of the code provided in this tutorial that has me very confused and, although my code includes it and everything works, it bugs me to not understand it. It's this part of the Scrollbar class:

I'm trying to override dispatchEvent(), with no success in the Flash IDE. Reviewing Adobe docs on the method, it should simply be:
override function name()
As demonstrated by Grant Skinner, this is commonly and easily performed:
override public function dispatchEvent(evt:Event):Boolean {
// code here
}
And while a thorough google search will repeat this syntax successfully used in Class files, doing so inside timeline code, natively in the Flash IDE is proving impossible. The first issue being that the use of public throws the error 1114: The public attribute can only be used inside a package.That was obvious, however upon removing that, running the following (on the first frame of a new .fla file):
override function dispatchEvent(evt:Event):Boolean {
trace(evt.type);
return super.dispatchEvent(evt);[code]..........
results in this error: 1024: Overriding a function that is not marked for override.
Documentation on this error implies that I failed to prefix the identically named function with the override statement, but obviously that's a fallacy, and I'm left flabbergasted as to what the solution may be.
To be clear, we know a class file will work, but that's an irrelavant issue. How do we get override function dispatchEvent() working in timeline code?
I have got an open source "Organisation Chart" component in Flex from the below link [URL]..But the component is in Flex 3, and I want the same in Flex 4.When I am trying to run the same in Flex 4, I am getting some weird errors :

Any one has any idea, Please help me with this.Also If any one knows any other "Org chart" component for Flex4, Please let me know.
I hsve a setp where a couple of classes inherit from a base class (events, plus common math). All derived classes implement the same set of methods. Another part of the program wants to instantiate any of these classes. So far I was creating empty functions in the base class and overriding them. Could an interface improve on that? I tried to list the common functions in an interface and use that as a datatype, but that would not let me use functions that the base class already inherits, in particular event dispatcher. Would I need to add these to the interface?
View 4 RepliesI have two SWFs: main.swf and external.swf. main.swf needs to access some methods in external.swf, so it loads external.swf into itself and uses getDefinitionByName("package.Class") to access the class and one of its methods:
var ExternalClass = getDefinitionByName("package.Class") as Class;
var ClassInstance = new ExternalClass();
var NeededFunction:Function = ClassInstance["NeededFunction"] as Function;
var response:String = NeededFunction(param);
Now, I need to extend the functionality of NeededFunction (which is a public method)... I know it's possible to override public methods, but how would I go about this with a dynamically loaded class?
I was thinking I could do something like this, but it doesn't work:
var ClassInstance["NeededFunction"] = function(param1:uint):String {
var newString = "Your number is: "+param1.toString(); //New functionality
return newString;
}

Let's say I have a Custom Event Class, and it has several Event types stored in static Constant:
[Code]...
Is there an easy way to validate that the type passed to the Constructor is one of the Static Constants of the Class, without having to check it against each value?
If I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()
package{
public class Character{
protected var _hp:uint = 50; //Character Health Points
protected var _power:uint = 5; //Damage dealt
[Code].....
I`m instancing a Character and a Player in the Main Timeline, all in frame 1.
When I use: ""player.attack(character)"" it works fine by itself.
So I added the if (defender._hp <= 0) this.win() which gives me the following error:
1061: Call to a possibly undefined method win through a reference with static type Character.
"defender" is a Character instance, "this" is a Player instance and "win()" is a Player method. I try to call the Player method inside a Character method using the Player instance adding the "." and his method name
Do I really need to define the win() function in the Character class? Is there a bypass to use a subclass method in a parent class method if it`s called from an instance of the subclass?
I was wondering why my current code for calling a setInterval on a function doesn't work inside my class.I have this code inside one function, calling a second function.
intID = setInterval(selfReferential, dupe, 30, 0x000000);
The selfReferential keyword refers to the current class,but was defined previously (selfReferential = this; ).I get no errors, but the dupe() function is never called.and I had the selfReferential variable replaced with the this keyword at one point as well.
I'm not sure that I'm on the right track here. I've got what is essentially a 'gateway' movieclip and depending on the CLICK a corresponding movieclip (form) is loaded -- these all being in their own AS file. There are multiple corresponding pages that will all load/close in their own fashion but the 'gateway' will reload in it's own function-- consequently, I have this function on the main_AS. Can I trigger this function from the sub class or do I need to move the 'reload' function to a 'reload' class.
View 2 RepliesI've been searching around trying to work this out for a while now. There's been various ideas popping up, like dispatchEvent etc but nothing that seems to be a clear, simple way of doing this.What I'm trying to do is call a function from a class seperate (but in the same folder as) my document class.Specifically, I want to 'spawn' an object and run a function within that object's class from my Main.as.The snippet I have at the moment is as follows;
In Main.as:
var object:class_Object = new class_Object();
object.spawn();

How can I run function of the main document class from a class of a MovieClip? I usually just used MovieClip(parent).function(), but now my MovieClip has another parent. Or what do I have to pass to the MovieClip class when creating the MovieClip to acess the main document class?

I keep getting an "undefined property" error when I try to call an external function from within the Doc class. I added the error message to the Doc Class below so you can see where it occurs.
If I take the code from the Tooltip.as below and place it on the FLA's main timeline I can get things working fine, but I would like to move all script to classes. The document class structure looks like this:
Drag_and_Drop.as
Code:
package {
import Tooltip;// Import custom class
public class Drag_and_Drop extends MovieClip {

I realize that I could just combine all the code in the Doc class to get it working, but it would be nice to separate out this particular code which has only one use.
Lets say I have a Main Document Class called Main. I also have a child class called childClass that call a function from the Main class and is also imported in the Main class. How should I call the function? I tried this , but when calling the function, it's getting me error.

I'm trying to have a class reference a variable within the document class and have scoured the web but can't seem to find a solution. It seems relatively simple, but is a major stumbling block for me.
I want the variable in the doc class to increment each time a draggable object is within bounds and snapped to a box in the subclass. By tracking successful snaps, the objects will be placed one under the other each time.
I have a Document class that instantiates a class named Other. I need to call a function in the Other class from the Document class.I'm getting this error: Call to a possibly undefined method OtherFunction through a reference with static type Other.I have read online that you need to use make the functions static or use a getter function but I'm unclear how to do that. I haven't been able to make it work and I feel like i'm missing something fundemental with this problem.below are simplified versions of the classes.

I have a document class called Main.as In the class constructor I have the following listener:

enter code here
var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent;
ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?
I have a class Debug with a function called trace inside it which puts a TextField on the stage and outputs the text. Now I am trying to get the Debug.trace() function to do a "normal" debug trace as well from within side itself. of course this causes a recursive loop. I am trying to figure out how I can access the top level separately. I tried using namespaces such as AS3::trace but to no luck.
I know a solution is to rename my function to stop the conflict, but I would like that to be a last resort. It is being used in quite alot of places throughout my entire code so replacing it everywhere is going to be a ballache.

My first experience is build an aquarium with a lot of fish swimming, and they can be clicked. When one of them is clicked we should receive a trace message saying ("I�m a Fish!"). To do this, I thought that the best way will be:
1- create a document class, named Main.as
2- create a base class, named Clicked.as
2- create a movie clip with a fish.
3- export the movieclip to actionscript. In the mc properties set Class as "fish" and Base Class as "Clicked".
