ActionScript Code:
1067: Implicit coercion of a value of type
__AS3__.vec:Vector.ie.aro.floorplanviewer.model.buildingVOs:ConfigurationVO>[code]....
which surprises me as ConfigurationVO inherits from NodeVO.Is the compiler really not able to figure out that a Vector of a superclass should be able to hold a reference to a Vector of a subclass?
I have a class which takes a Vector.<DisplayObject> in it's constructor. I had expected it to be ok to create instances of this class by passing Vectors of types that are subclasses to the DisplayObject class (in this case Sprite ans SimpleButton). But it doesn't work. And casting these Vectors as Vector.<DisplayObject> when declaring the instances doesn't work either. [code]...

I am currently being confused by the Vector class.I wrote a beautiful XML to TypedClass parser. Works beautifully and without fault. UNTIL a co-worker noticed we got a Conversion Error for Vector.<Number> to Vector.<*>.
Every Vector I've ever tested all extend Vector.<*>.
Vector.<Sprite>, Vector.<String>, Vector.<Point>, Vector.<Boolean>, Vector.<TextField>, Vector.<CustomObject>, etc etc etc. ALL of them.
<type name="__AS3__.vec::Vector.<String>" base="__AS3__.vec::Vector.<*>" isDynamic="true" isFinal="false" isStatic="false">
<extendsClass type="__AS3__.vec::Vector.<*>"/>
[code]...
But then when I use describeType on Vector.<Number>, Vector.<uint> and Vector.<int>.
<type name="__AS3__.vec::Vector.<Number>" base="Object" isDynamic="true" isFinal="true" isStatic="false">
<extendsClass type="Object"/>
<constructor>
[code]....
Now I have accounted for these 3 vectors individually as even uint and int does not extend Vector.<Number> as I would have expected.
And my parsing function works for all types correctly again. But my confusion comes as to WHY this is the case, and why I couldn't find any documentation on the subject.
Is it possible to obtain a Class reference to a Vector.<T>? I tried the following code:var cls : Class = Vector.<int>;But it fails with a coercion error, presumably because Vector.<T> is also a global function. Is there a simple way around this?
View 1 RepliesI am implementing garbage collection within an AS3 app. In one part, several display objects are created within a loop like so:
for(var i:uint = 0; i <= this._exampleVector.length - 1; i++)
{
this._customText = new CustomTextObject(this._exampleVector[i].playlistText), this._customTextWidth);
[Code].....
When I try to make the _customText within the _customTextVector null, this does not work. It only makes the index inside the Vector null. how to do this or another method to garbage collect?

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 RepliesWhat 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.
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.
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") ???
View 1 RepliesSo, how would you create a class that can access a variable in the class where the subClass was created(superclass), I realise this might be unclear so in example

I have a large vector drawing (imagine 5000x5000) that i want to break up into separate pieces. I know that I can convert this vector drawing into a bitmap and then use the copyPixels method to create many separate bitmaps of the different regions of the original vector drawing, but is there any way to subdivide it into movieclips that just contain vector graphics instead of a bitmap?The reason im dividing a big chunk of vector graphics into smaller pieces is for performance reasons, so flash would only render a small part of this big chunk at a time (only certain regions/voxels/subdivisions are rendered at a time). But bitmaps apparently take up a lot of memory and the system im using would take much less memory if these subdivisions could be preserved in their original vector graphics form.
I imagine I could use masks somehow to achieve this effect (for each subdivision, duplicate the huge image and mask only the region that the subdivision represents), but I dont know the performance costs of masking or if this will create other problems.So is there anyway to split up a movieclip of vector graphics into smaller movieclips of vector graphics the same way copyPixels can with bitmaps?
What passes to a subclass extending from a main or superclass, be it document or extending from a general MovieClip class etc? Does it pass absolutely everything from the superclass? That is to say, instance functions, variables defined inside these functions etc? Or just constructor variables? What passes through and does 'static' affect the transference of these values?
View 2 RepliesI've run into an extremely odd problem. I'll give a code example to start. This is the superclass Building.
Code:
public var allowsEnemyMovement:Boolean = true;
public var information:String = "";
public var buildingName:String ="";
[Code]...
Now here's the odd part. Only SOME of the variables defined in the superclass do this. the variable information, buildingName and health all will take the default value from the super class. But the variable defenseValue will take its value from Factory's constructor. What am I doing wrong here? I would like to keep default values in the superclass so that I don't end up with null pointer errors later just in case.
It's early days in my AS3 learning, and I'm looking for a little clarification regarding a variable typed to a superclass (in this case var mySpinner:MovieClip) which contains a reference to an new instance of a subclass (in this case Spinner.) I am trying to get my head around why my code compiles and runs and I am able to call the method rotater() on mySpinner even though mySpinner is typed as MovieClip, and the MovieClip class does not contain the method rotater().
On page 163 of the official Adobe Programming ActionScript 3.0 documentation it says the following, which I believe is related to my situation, but I am still in need of clarification:
"Because each class defines a data type, the use of inheritance creates a special relationship between a base class and a class that extends it. A subclass is guaranteed to possess all the properties of its base class, which means that an instance of a subclass can always be substituted for an instance of the base class."
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 have a class called Animal that has a method foo() and I call it out within the Animal class.
Code:
protected function foo():void
{
trace("Animal");
}
I also have a class called Cat that extends Animal and overrides the method foo()
Code:
override protected function foo():void
{
trace("Cat");
}
However when calling the function foo() from the superclass it traces out Animal not Cat (using a Cat object).How can I make superclass call out methods in the subclass?
I already Import PSD layers into the Flash CS3 project. But it Imported as a PNG image and not a vector shape.I am using it in a web page and Its size is not suitable for fast loading.
How can I import PSD layers to the flash projects as vector shapse?
I have a simple landing page that im making for a website.The title to the site. Just plain simple static text but its just always edgy and aliased? I even tried making it orginally in a very large font size breaking it up and then reducing it in size. Still no luck.But when i zoom in using the right click menu its starts sharpening up and in real close-up seems razor sharp. But when the page is displayed at 100% size the text which is now much smaller is aliased.
View 21 RepliesThe great thing about vectors is the data typing / autoComplete.. The thing about them that I hate is the numeric index and the resource intensive retrieval methods you need to pull an element.
so with objects:
myObject["myObjectKey"]
is great, fast, etc. BUT there's no data typing myVector[0].myProperty is fantastic for auto complete, but there's no quick index, instead a bunch of for loop logic that can get really messy in more complicated data models where there are a lot of relationships. Does anybody know of an elegant hybrid solution aside from things like
var myProperty:MyFavoriteDataModel = myObject["myProperty"] as MyFavoriteDataModel;
I have seen flash games where the player can actually draw objects. Meaning they have like a pen cursor in the game, and they can just start creating vector art. I have a game in mind where it might be a cool feature to have the user draw a few things. I bet this is a heavy subject so I am not asking for every bit of code I'd need to create something like this, but I have searched quite a lot for anything remotely brushing on this subject and clearly I have no idea what I should be punching into google.
View 3 RepliesI've imported a vector graphic from AI into my stage. When I click on the vector graphic that's been converted to movie clip symbol and drill down to the vector level, as soon as I insert a keyframe in the timeline, I no longer can use an eraser to edit the vector graphic. It automatically move up one level as soon as I insert a keyframe. Does anyone have any idea why I'm getting this behavior? I want to create a hand written effect with this vector grachic.If I draw a vector square on the stage, convert to movie cli, double double click the movie and then I am able to edit or change the vector shap but that's not the case with the imported AI file.

View 1 RepliesI am trying to use the new Vector class introduced in Flash 10. Tried compiling the code using mxmlc but am getting this error message:
Error: Type was not found or was not a compile-time constant: Vector.
public var selectedRoutes:Vector.<Route>;
What is the general consensus about the viability of using this feature? Can you do introspection of the Vector with describeType and get the type the Vector contains at runtime?
Why would bitmap outperform vector?My Flash is for a large Kiosk, with rich media requirements and must function accurately as a counter. I want to keep everything vector for scalability. When I did a simple FPS test, I noticed my Bitmap version performed perfectly, and the all vector file was noticeably slower.
- only text and bitmap perform well, not vector
- background and clouds OK, but more layers slow it down
