Actionscript :: Overriding A Protected Function In A Subclass?
Sep 26, 2011
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?
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]..........
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 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...
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'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 :
1024: Overriding a function that is not marked for override. OrgChart.as
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.
Can I access a static variable of a subClass' subClass? I don't want to instantiate it, just looking to get the variable because it has already been initialized by the subClass.example:
package { public class A extends MovieClip { private var classB:B = new B();
I seem to be having some difficulty calling a function from my subclass to home/doc class. I am trying to click the button called "GalleryButton.swf" (located in in Home page.as) to add a function called "addGal". (Also located in in Home page.as) to call a function from my main/doc class to work, called "gallery". Which indeed removes my home page from the stage and adds my gallery page to the stage.
I receive this error: ReferenceError: Error #1069: Property gallery not found on flash.display.Stage and there is no default value. at HomeClip/addGal()
EXAMPLE CODE - NOT FULL I have import code such as: import flash.net.URLRequest; import flash.display.LoaderInfo; etc etc. Because the pages to transition using buttons from the navigation class, its just that a button from homeClip.as, won't call the function "gallery" on the main class needed to add the gallery page to the stage.
Main Class - (holds the functions to add pages) Code: package { public function StartHome() { trace("addingHome"); addChild(_NavigationBar); //ADDS NAVIGATION CLASS// _NavigationBar.name="NavBar"; } public function home() { [Code] .....
package{ public interface GraphADT{ function addNode(newNode:Node):Boolean;[code]........
Having this setup here is giving me errors, namely:
1144: Interface method addNode in namespace GraphADT is implemented with an incompatible signature in class AdjacancyListGraph.
Upon closer inspection it was apparent that AS3 doesn't like the different parameter types from the different Graph classes newNode:Node from Graph , and newNode:AwareNode from AdjacancyListGraph
However I don't understand why that would be a problem since AwareNode is a subClass of Node.Is there any way I can make my code work, while keeping the integrity of the code?
I have a problem I just can't seem to solve.I have an FLA .. (augmented.fla)I have a movieclip inside of augmented.fla with a class name of myMaterial that has the following code on it's timeline.
ActionScript Code: var request:URLRequest = new URLRequest("main.swf");
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?
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.
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:
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 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 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...
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]
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?
