I 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?
From which version of the Flex SDK is the Vector class available for Adobe AIR applications? I want to use a library that contains some code with Vectors. But my Flex Builder 3 (Flex SDK 3.0) doesnt seem to support it.

View 1 RepliesIs 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 Repliesimport flash.geom.Point; I am trying to write a game using the new Vector class. Then Vector will be composed of flash.geom.Point (s). However, when I try to use the concat funtion to return another vector with a series of Points added to the end of the vector, I will get: TypeError: Error #1034: Type Coercion failed: cannot convert flash.geom::Point@bce8901 to __AS3__.vec.Vector.<*>. at Vector.<*>$/castToThisType() Action script is saying that I am trying to convert a vector to Point to a vector. I do not see how this is the case. In the example below, I have declared adjoiningPoints to be of:var adjoiningPoints:Vector.<Point>;
When I call path.concat( myNextPoint ); I get the above error. In order to troubleshoot the problem, added the additional lines declaring 'iAPath'. When I work with the arrays everything works fine. The arrays are entirely populated with points and there is no error.

i seem to be having some problems with the Vector class in actionscript 3 in a Flex Project or an ActionScript Project it is possible to do this var v:Vector.<String>; But when i do the same thing in a Flex Library Project (to create an SWC) then i get the following error on that line of code 1046: Type was not found or was not a compile-time constant: String.
so when using Flex Library Project it fails..., but when i compile the same thing using compc there are no problems any idea why only the library project is complaining about Vector ?

As you all know, Vector support type checking by added Type parameter.
var v:Vector.<String> = new Vector.<String>();
I wonder if I am able to create a custom class that have Type parameter, something like this
var myClassInstance: MyClassDefinition.<String>;
Are there some online resource/page/repository where I can view the sources of action script Vector class?

Is there no way to extend the vector class or write functions for a generic vector without specifying the class? There are a few basic reusable functions I want to use and I'd prefer to stick with vectors rather than arrays.

1,11.15126526
2,11.28306635
3,10.78296071
4,10.79878325
The CSV reader class works and produces a Vector.<Point> ... However the container class (which includes an instance of the CSVFile class) needs to access the resultant Vector. Whenever I 'return' the Vector.<Point> to the container via a CSV method it is always empty...I don't know if its something to do with the size of the Vector<> or what?
I would like to take advantage of all the goodness of the newer Vector class for FP10, but it seems it is marked as final. I am doing some intensive mathematical processing in Actionscript, and repeatedly process arrays of Numbers. I have previously been using my own subclass of Array(I call it NumericArray), with added functions such as sum(), mean(), add(), multiply(), etc. This works very well and allows for some clean OO code. However, I am finding through profiling that about 95% of my processing time occurs in the functions of these objects. I need more performance out of these arrays.
I want to use a Vector, as it provides some performance enhancements. I want to specifically use a Vector.<Number>. Unfortunately, I cannot subclass Vector as it is marked final. What is the best and cleanest way to imitate what I was previously doing with a subclass of Array, to a Vector.<Number>?
I have thought about passing around Vector.<Number> variables instead of my custom class and just using utility functions to manipulate, but this is not good OO design and will be a pain to use, not to mention ugly.
I'm getting
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 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.

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?
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.

- only text and bitmap perform well, not vector
- background and clouds OK, but more layers slow it down
I'm looking to build a website that has a flash interface and allows visitors to upload vector art in a number of file formats such as SVG, EPS and AI.
I have two rather large problems...
1) I need to load the original vector art, probably convert it to FLV and display it in my flash application.
2) After the user potentially loads a number of images, adds some text, rotates or transforms some elements, I need to save the resulting composition into a vector art format that I can print.
I'm not much of an AS developer...my experience is mostly in .NET/C# & C++. I'm looking for a good library or API that provides the functionality I will need to convert different image formats and save the results. How much of this can be done using Flash / AS...? How much in C#...?
