ActionScript 3.0 :: Overriding A CreateLabel Method?
Sep 9, 2009
I would like to create many different labels which have identical properties but which have a different position and a different name. I created a main class called DefaultLabel which defines the format of a standard label and then I created a seperate class called Label which overrides the createLabel method with a different position and a different label text.
Ever since I added the Label class, my original label doesnt appear anymore and I receive error msgs (1119) stating that my formating properties (text, color, etc) are not defined and that they reference to a static type Label. Unfortunately I do not have Flash installed in English so I cant give you the original msg. Everything worked fine when I just created one standard label so I guess I made a mistake with overriding...
The various labels should be created in this class:
PHP Code:
package {
public class Label extends DefaultLabel
{
private var myLabel1 : Label = new Label();
I've run into a peculiar problem while trying to make use of the Proxy class and override the getProperty() method. I've attached my example class code below:
when extending a class, is it impossible to override a method without also matching the parameters?for example, i'd like to use the method's name, in this case it's a socket extension and the method i want to override is connect. however, i want to request additional parameters that the stock connect function does not request.
is the only alternative to create my own connect-like method with my own parameters, call super.connect from this function and override the stock connect function to throw an error if it's called?
I 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; }
I have been assigned to work on a Java/Flash/BlazeDS project. When I pull down the project code, I need to run an Ant script as part of the setup. This script eventually compiles the Flash code, as seen below.[code]...
I 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?
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...
Trying to find a straight answer for this. I am going to be creating some sub classes in actionscript 3. I was wanting to know if it is possible to override the parent class. If so, do I need to put a override assigner on the parent class method or what.
I've seen methods for overriding addChild inside of movieclips, but can you do it at the upper-most root level? As in, overriding it on the main timeline.
class Base { public var space:Number; } which gets extended by class Desc extends Base {
[Code]...
This doesn't compile. Say, you don't have control of the base class, what ways is there implement the same thing? The obvious is create a function setSpace(), but this object is being embedded in an already existing system that use the public space.
I have been playing with new (or not so new) MouseCursorData to at last stop using mouseX or MouseMove. Better performence is better work but I have a problem with MouseCursorData limitation. As you know MouseCursorData has 32x32 pixels for a custom cursor. Is there any way to overrid this limit?[code]
I'm looking to speed up my game, and I know that people keep saying the default prototypes are slow, and so I'm wanting to swap them out with better ones, like I found one that makes split() 10x faster than default...
super.zValue(n) should be super.zValue = n ........ wowy Nothing to see here folks, just keep moving on I'm having some difficulties in working with the as3 way of overriding methods.. specifically setters. I'm a recent convert from working with as2 for a few years, so some of these quirks are beyond me right now.Here are my two classes:class tempBase in package core
Code: package core { import flash.display.MovieClip; public class tempBase extends MovieClip
[code]....
I do not have any errors for the override of baseFunction, but on compile I get the error 1061: Call to a possibly undefined method zValue through a reference with static type core:tempBase.In as2, this would have been perfectly acceptable (even without the override function), and was incredibly useful in creating my class structures.
I recently started on a new portfolio site and can't seem to figure out why some of my swfs override the html pixel size. I have included a link to the page. When you click on 'portfolio' there should be three thumbnails on the right. When you click on one of the thumbnails you'll see the size shift.
I frequently find myself wanting more granular control of the width/height properties. Consider either of the following cases:
- The DisplayObject is clipped with DisplayObject.mask, but Flash reports unmasked width. - An image is displayed with a transform cage drawn over it. The width of the cage shouldn't be calculated when determining the DisplayObject's width.
The naive way to solve this problem is to override the width getter of the DisplayObject in question. The problem is that the core implementation of DisplayObject.width is written in native code. If after overriding the width getter, I call overridenObject.width, I get what I want; however, if I call overriddenObject.parent.width, DisplayObject.width ignores my override and calculates the dimensions based on its own internal display list representation.
Does anyone know of a technique to limit which children are considered when calculating width without having to override every parent's width getter? I've tried overriding width, getRect, getBounds, and scrollRect, but none of them seem to be referenced by DisplayObject.width's native implementation.
I'm an animator trying to use actionscript along with timeline animation.The setup is flock>fly>wings flock movieclip 30f long, the script looping, starting multiple fly movieclips at different points.
fly movieclip 30f long, controls wings0 movieclip timeline (3 frames, each with a movieclip). Frame1: wings0.gotoAndStop(2) Frame24: wings0.gotoAndStop(1) Frame48: wings0.gotoAndStop(3)
From flock timeline I'm trying to override actions in fly3. to call a different wings0 animation.
I have an external CSS file which defines the style for the Button tag.Button {fontSize 11; blah...}I'm trying to override this style for the buttons of a ToggleButtonBar:<mx:ToggleButtonBar dataProvider="{pm.portalNavigation}" fontSize="16" />Unfortunately, this doesn't seem to work. The fontSize stays at 11. How can I override the external CSS to resize the buttons in my ButtonBar?
I have a class (Wall) that inherits from Sprite.Sprite already has width and height properties. But for wall, I need to do some other additional calculations when the properties change (f.e. make sure the new size won't cause it to overlap any other walls).So, how do I set the width property inherited from the Sprite class from within the width setter of the Wall? (or perhaps there is an alternative way to do my bounds checking whenever width is set?)[code]
I'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?
Is there a way to override the width (for a getter) on a Sprite?I see examples of how to override the setter but not the getterI need to do something like
override public function get width():Number { if (onecase) { return this width;
I'm embedded in an environment (Adobe AIR) where I cannot override idFinishLaunchingWithOptions. Is there any other way to get those options? Are they stored in some global variable somewhere? Or does anyone know how to get those options in AIR
I have been using console.log external calls in my code to make debugging easier in the browser but I have found that when i pass the code on to someone else they are always asking why I am using an "alert" method instead of trace and as they edit the piece they naturally will use trace calls and I was wondering if either of the following is possible?
1. Is there a way to override the trace method? When I try with the following code I get an error: 1020 Method marked override must override another method.
ActionScript Code: public override function trace(arguments:restParam):void{ }
2. If I can't override trace, does it dispatch some event that I don't know about that I can listen for? (normally I would try to figure this out using asdocs but whenever i try to visit the "trace" documentation I just get a page cannot be displayed error :S
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 am importing flash.display.MovieClip and have public class DisablingButtons extends MovieClip.Code below...[code]..........
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?
I want to override the dispatchEvent method while inheriting from flash.display.Sprite. Whenever an event gets dispatched now like ADDED_TO_STAGE and CLICK it will get through dispatchEvent in my theory. However there is no single trace he'll get through dispatchEvent.. so the events get dispatched internally from some where else?
I am much more familiar with Java's semantics of class and interface than with Actionscript semantics, but I have an example of some code that works in Java and doesn't work in Actionscript. This descrepency is a serious problem in that I am trying to code generate my Actionscript value objects from the Java DTOs and unless the semantics are the same, I am in deep trouble.
Here's the code that works in Java and fails to compile in Actionscript:
[Code]...
I don't understand why class B throws a compile error about an incompatible signature for "makeCopy" when clearly interface B extends interface A...thus there is no violation of type or incompatibility. If this is just an Actionscript limitation, can anyone suggest a way to recode?
NOTE: I already tried changing interface B to this and it threw an error in interface B (which work in Java):public interface Ib extends Ia {function makeCopy():Ib;}
I don't know if this is the right term "overriding timeline functions"... I'am making presentation wich has 8 navigation buttons..the presentation goes like this...when you press one button it goes to this buttons segment and play's it, when is finished it comes back to navigation by action gotoAndPlay ("menu")...myproblem is the last button...wich says Whole presentation...i cannot duplicate the presentation because it has too much keyframes and max is 16000 (i am not master atFlash )...so i would like somehow to cancel all the gotoAndPlay actions if it is possible?? so when i click the last button (whole presentation)...the playback doesen't jump back to menu...but plays til the end.
