just made my jump into OOP and I am quite excited to find out such marvelous things that I did not know. If someone has a quick answer or can point me in some direction please reply to this question: How can I, if at all possible, modify a function from a superclass but preserving all of it's functionality? I know about the "override public function" but that is not precisely what I want.
View 5 RepliesI'm trying to override a subclass's method but I think I need access to the superclass one higher up in the hierarchy. So I'd like to do something like super.super.methodName();
FYI, the actual problem I'm trying to solve should be explained by my code below:
public class A extends UIComponent{
override protected function keyDownHandler(event:KeyboardEvent):void{
super.keyDownHandler(event);
[Code]....
If I use the class A's KeyDownHandler method, you will see that remove() is called regardless. However, the docs state that I need to call UIComponent.keyDownHandler whenever I subclass UIComponent. Of course this works for the first subclass, but not that subclass's subclasses.
I realise that I could put the functionality all into A with something like if(this is B){...} but that seems to me to be a hack.
I've struggled to get my animation working the way it is currently and now the functionality has been requested to change and quite frankly I just don't think I would be able to work it out as I'm not a Flash developer.[URL]It's a sliding image gallery. There are 13 images and when you roll your mouse over an image a set of filters are applied (to the movieclip wrapping the image) that gives it a glow/drop shadow effect.The images move based on the mouse position.
1. The animation still needs to move on the mouse position, but also the when the animation loads it should automatically move in one direction (images moving left across the stage) but when the user rolls their mouse over the animation then the mouse position takes control. Once the user rolls their mouse away from the animation then the images need to keep moving in the last direction (at a set speed)
2. When the user rolls their mouse over an image it needs to get bigger - but wont some of the images then overlap, so each movieclip would then have to dynamically move to the top of the stack to make sure they overlap the other images correctly
3. The animation needs to loop!?
Anyone know how to add keyboard (up and down arrows) functionality to move the scroll up and down? And clicking the scroll bar area to move the scroll?

So I've been trying to add tooltip functionality, but I'm getting some strange behavior. e.g. duplicate clips appearing, clip not loading completely, clip not fading in correctly.
Goal: Tooltip box that quickly fades in after a short delay. Must resize to accomodate varying number of lines and line lenghts.
Structure: The tooltip movieclip holds three other clips in this layer order:
1) clip with a texbox
2) clip with the yellow box background
3) clip with a black box for the border (this box is 2 pixels larger than the box background, effectively leaving a 1 pixel border.)
These clips exist transparent on a timeline for about a half second, then start to fade in to full opacity by the last frame. So, the button code consists of assigning some text to a variable, then calling a function to make the tooltip visible via rollOver, and a hide function on rollOut. The idea is:
RollOver
1) use startDrag to place the clip by the mouse
2) Assign the text to the text box
3) Resize the background and border to match the size of the current text
4) Make the tooltip clip _visible = true
5) Play the tooltip clip, causing the delay and then fade in. (stop at last frame)
RollOut
1) make tooltip clip _visible = false
2) gotoAndStop(1); (reset clip)
Now for the problems:
1) Improper (loading?)
Upon opening the flash file, If I do anything that causes the tooltip move to stop playing, or if the showTooltip() function get called before that playback is done, the clip will no longer play. And it will be stuck at whatever frame it was on at the time of interrupt everytime the tooltip is shown thereafter.
2) Duplicate clips
If my main timeline has more than one frame, and extra instance of the tooltip appears from 'somewhere' - which is odd because there is only one tooltip movieclip and it's there from the begining.
3) Fade not working
The setting of the box size seems to be somehow interfering with the alpha of the parent clip. I've had to resort to using _visible on the tooltip timeline to control the delayed visibility of the box. (Removal of the box sizing causes the clip to fade properly.)
Relevant code:
Main timeline
startDrag("_root.tooltip", true); tooltip._visible = false;
Tooltip clip
onClipEvent(load) {
function showTooltip() {

View 3 RepliesI'm creating an image scroller in AS2 that pulls images into Flash from an external folder, as determined by an XML file. The program use a MovieClipLoader to load the external images into series of empty, and temporarily invisible, movie clips that are created inside a for loop. Once the attached listener determines that the clips are all loaded, their visibility is turned on and they begin scrolling. Everything had been going fine, until I tried to add functionality to each of the four images that had been loaded. All I want to do is generate a trace statement that says "success" when I mouse over each of the four external images in the scroller. I can use that as a springboard to continue working...
Here is the problem: "Success" IS traced out upon rollover, but only once - when you roll over the last image that was pulled in from the RSS feed and into the for loop. It does not apply to any of the other images. It seems like the functionality on the other images is created but them somehow instantly destroyed or overwritten as the for loop continues to run and the MovieClipListener updates itself. But I am not sure. If this were simply a series of movie clips or images being pulled in from the Flash library, I wouldn't have this problem. However, the external images and the MovieClipLoader are confusing things.
//Start For Loop Pulling from XML File {
//create movie clip that will hold next image pulled in from XML file var cImageHolder:MovieClip = scrollerBase.createEmptyMovieClip
("imageHolder" + i + whichRow, scrollerBase.getNextHighestDepth());
var mcLoader:MovieClipLoader = new MovieClipLoader();

I have a video player that doesn't have "seek from unloaded time" functionality. I want to add it now. I simply load video like this;
stream.play("vidurl.flv");
(pseudo streaming)
Server side is ready. I can call videos like videourl.flv?start=xxx but cant play them in player cuz video comes without metadata
To sum up:
1. stream.play("vidurl.flv"); works, video plays
2. user clicks to seek bar. on unloaded part. I get the position and convert it to seconds
stream.play("vidurl.flv?start=10");
Doesn't work! No metadata what I should do after?
My application creates instances of a movie clip (located in the library) based on XML data. Now I want to add individual button functionality to these instances, and I'm stumped.
I'm basically creating instances of clickable doors, the data of which are fetched from an external XML file. The number of doors (doorCount) is calculated directly from the number of "door" nodes in the XML, so it needs to be fully dynamic. Essentially, I want to have a single function that each instance can use by passing in their individual XML data. Clicking a door would first open the door (or something similar), and clicking it again would lead to a link, listed in each instance node.
Here's the loop, where the instances are created:
[Code].....
I don't really know where to begin. Am I able to declare an eventListener inside the loop? How do I pass the "number" of the door to the function called by the eventListener? Or should I somehow pass the door-specific link (and any other node data) to the function directly from the loop?
I'm looking for a way to extend the functionality of the HTMLEditor control that the Ajax Control Toolkit supplies for ASP.net. I would like to add video and flash functionality to the editor (buttons, allowed tags, etc).
To my knowledge, this is rather easy: plop in an embed tag with the correct parameters and it just works; I have videos running in the preview window of the editor.
Unfortunately, the tag is stripped away when saving the HTML-code and updating it in the database.
Hence, I would like to ask if there is any way of adding this functionality apart from manually adding the changes in the source control repository of the Ajax Control Toolkit and recompiling it.
I have a movie with 5 movieclips named section1_mc, section2_mc, section3_mc, etcI want to advance to frames 1 - 5 by clicking in each of the movieclips.

I'm trying to extend the functionality (not extend the class itself) of the netconnection.call() function by enclosing a netconnection instance in a class.What I'm attempting to do is have a function that I have defined as "call" make a call to mynetconnection.call("", null, ...rest). For example:
Code:
public function call(method:String, ...rest):void {
this.mync.call(method, null, rest);
}
I have tried repeatedly to do this, and it's not working. The rest parameter feeds the parameters into an array, but is there any way to undo that on the inside of the method and pass a pseudo-list of parameters to nc.call() so that it will see it correctly?Is it possible to duplicate the functionality of a ...rest parameter into another function?

View 2 RepliesI got a huge problem trying to color objects that are flying around in my space game. When I shoot and hit them - the affected enemies shall blink. The graphics are pre-rendered (i.e. there's an rotation array and function where the degrees and their appropriate rotation for the objects are stored / calculated for better performance).
So - my idea was to enhance that rotation function with a functionality for additional coloring; but the colored AND rotated objects shall be stored apart of the normal rotated objects. To accomplish this I made a nested array: in row one there are 360 rotated graphics of one object and in row two there are 360 graphics of a rotated and colored object.

View 1 RepliesI am working on a project that is utilizing Flash Professional and Flash Builder. The art team creates assets in Flash Pro and publishes the project as a SWC. I then copy the SWC into my Flash Builder project's lib directory and access the assets through that. The art team is creating a lot of the same type of thing; let's say they're making lots of lizard symbols/components. All of these lizards have similar animations (walk_left, walk_right, etc.) and because of this they all have constants defined in ActionScript (WALK_RIGHT_START, WALK_RIGHT_END, etc.) relating to the keyframes in their animations.
From the Flex side of things, whichever Lizard I load, I want to be able to tell it to walk left. So I created a superclass in Flash Professional and now all of the AS classes for the lizards in Flash Professional extend this class - Lizard.as This is all fine and good, but when I want to add more complexities to my lizards, I don't want to have to open up the Flash Pro project, edit the class, recompile the SWC, send it back to Flex, and then test it out. I want to be able to have my Lizard superclass available for editing in Flex - so I made another superclass in Flex: Lizard.mxml
In Flex, each lizard component (like Gecko.mxml) currently extends Lizard.mxml, and each contains an AS component defined in the SWC (Gecko.as in this case). This seems pretty convoluted: An mxml component extending an mxml superclass, containing an AS component which extends an AS superclass. What I'd like to do is define one superclass in the Flex project, have my Flash Pro defined components extend this class (which is the part I believe to impossible), and then have my Flex Components (Gecko.mxml) extend those.
1: Is there a way to set superclass variables from within a subclass? I can't seem to accomplish it.
2: Also, why does it seem when I call a function, the superclass version is called instead of the sub? I construct the class using the sub, so whats the matter?
3: In one of the classes, I want to push a MovieClip it creates into an array, it works, but I get an undefined, then the value.
4: I have 3 levels of inheritance in my classes Specials -> Human -> Player, who do i call each one correctly from one another?
I have a Hero class that extends a Unit class that extends a SelectableObject class.[code]I have a movieclip in the library that links to the Hero. Inside the movieclip is another movieclip with the instance name "selector".In the Hero I can use selector.gotoAndStop (n) because the movieclip is linked to that class, but I can't do that for the SelectableObject because it's not linked to that.Is there a way to make selector.gotoAndStop (n) work for the SelectableObject? I can't even do var something:* = this.selector because the movieclip isn't linked to it.Or should I just remove the instance name for the selector in the movieclip so I can declare var selector:* = this.getChildAt (1) in the SelectableObject (the selector being the second child)?
View 3 RepliesIs there any non-hacky way to determine wether a class' superclass implements a particular interface?
For example, assume I've got:
class A extends EventDispatcher implements StuffHolder {
protected function get myStuff():Stuff { ... };

How could I perform that super is StuffHolder test in a way that, well, works? In this case, it always returns true.
What I would like to do is to call a method from a superclass in a subclass. Specifically I want to be able to add the subclass as a child of the superclass but without physically having to type addChild in the superclass (but I will have to type it in the subclass). For now I'm just trying to call a method in the superclass that draws some text from a subclass.
Here is the MAIN class (the superclass)
package
{
import flash.display.*;
import flash.events.*;
[Code].....
The code doesn't compile, I get "Call to a possibly undefined method DRAWTEXT through a reference with a static type class".
I realize there are otherways to display text on the screen. I just need to learn how to call superclass methods.
This is basically the opposite of what I was trying to do earlier. I just need to know how to change a subclass variable from it's superclass. So if I were to make an object in a class how would I dynamically change a variable in that object from the original class that I made it in?
Suppose this is the main function of my main class:
public function MAIN()
{
new OBJECT_square().CREATE(this,100,100);
OBJECT_square.X = 40;
}
Changing the X value in this way is not working. I realize I can set/change the X value when I make a new subclass but I need to be able to change it as I go. I also realize I can change it from within the subclass but this isn't what I want.
For some time now I have been making a very easy game for iPhone in flash using as3. Recently I came in contact with a small problem, which is why I am posting this!
The problem: I have a superclass from which everything derives. In the superclass I initiate and place an Object on stage.
1. var myObject:typeA = new typeA();
2. stage.addChild(myObject);
As you can see this object follows the class 'typeA' which, ocf, has its own actionscript file. Inside of this file I have declared a global variable of type string.
What I want to do is change the varbiable on the new object from the superclass. Therefor I tried as following:
1. myObject.myVariable = 'someSortOfString';
Unfortunatly it didn't work and so I wonder how to do this; change a subclass' variable from the superclass.
In Actionscript 3, if I'm given a Class object, is there any way to determine if that class extends from another given class? I don't want to instantiate the class to check it with the is keyword, though.

I have an abstract superclass which has around 300 subclasses. I would like to log when certain methods on this parent are called, and I'd like to know the name of the subclass thats making the call. Is there any way to do this without rewriting all my subclasses to explicitly pass their names upwards to the parent's logging method? E.g., let's say I have a superclass Foo with a method writeLog(str). Foo has a subclass called FooBar, which calls super.writeLog("hello"). Can writelog just inherently figure out that a FooBar called it, without the need to rewrite everything so that we have to call super.writeLog("hello", "FooBar") ???
