ActionScript 3.0 :: Return Vector Object From Composing Class
Mar 16, 2011
I have a CSV reader class that parses a CSV file.....
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'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):
I found myself loading a new XML file every day and so decided to create a small class that will load the xml file and return it.The class is loading the file but when i try to return it to a new xml object in the document class it doesnt load it.I think that it's something to with the return being in a nested function but i tried a few ways and non seems to work.
[DOCUMENT CLASS] loadXML:LoadXML = new LoadXML(); myXML:XML = new XML(loadXML.loadXMLFile("gallery.xml"));[code].....
i need to be able to launch pdf files from a .exe off a cd. simple enough. the problem starts here.... when i wiew the movie using .swf or .exe some images shift a tiny bit and then shif back during some of the animations. (god knows why but it dosent look great) when viewing the movie over a browser however there is no such problem. so here's where i need help. i would like to launch a browser window with no toolbars and such fit to the flash movie that can launch pdf's. again, i can launch the .exe from the cd and furthermore launch the pdf's but some images shift for some reason.. is there anyway possible to get around the security features in flash that wont allow you to launch a local file from a .swf file?
It seems that dropTarget only returns the name of the object that is directly under the mouse. Does anyone know whether there is a simple way for it return the name of the object that is under the entire bounding box of the object being dragged?
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.
First: When creating a Vector, does it have to contain a Flash data type (uint, int, Number) or can I have a Vector of objects I created classes for?
Second :I cannot instantiate a Vector object. All of the documentation I am finding is saying[code]
I get "1084: Syntax Error: expecting identifier before lessthan". I was thinking that maybe I needed to include a library, but the error seems like it knows that I am trying to create a Vector.
If I have declared my vectos object as such ActionScript Code:
private var _delsUI:Vector.<Single> = new Vector.<Single>();
fill it with data like:
ActionScript Code: _delsUI.push(newListing);
Then later on I decide to use this: ActionScript Code: _delsUI = new Vector.<Single>();
Will this essentially destroy all objects and prepare them for GC if there are no other references any where else? or do I have to loop through the entire Vector and delete and set null each object?
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?
Why is it that I can never change a vector object's color? I mean I would think it'd be as simple as changing the fill color but that does nothing.
And why is it that copying and pasting vector objects from illustrator very inconsistent? Sometimes I get the exact copy, and other times their's three anchor points missing, very much screwing up the look of the object. Also, when I import a vector png image made in photoshop to flash, the fill is hollow at times.
I'm having a very weird problem with a vector in my application.
Details...I have the following classes.
Person,Player,PlayerController.
Player extends Person. Person extends ObjectProxy in order to enable binding.So the Player class has the [Bindable] tag.The PlayerController class contains a remote object calling a php method to receive a firstname and a lastname and when the CallResponder gets the result from the call,the result handler creates a Player instance. At that moment I am trying to push the player object into a Vector..
The problem is the following.Every time the push method is called, the vector is being populated with the last player that was created but not just in the end of the vector. It replaces the other instances as well! So the vector always contains the most recent player instance but in every position of it.I have also tried doing it with an Array and the results are the same.
So far, I have a class that creates a Vector object, and pushes data into it:
ActionScript Code: public var mList:Vector.<cusClass> = new Vector.<cusClass>();
The data is read by a second class like so:
ActionScript Code: trace(firstClass.mList);
The problem Im having is take that same Vector and passing it into a third class (from the second class) as an argument in a method: ActionScript Code: views.mUpListing(firstClass.mList);
import 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 ?
I am creating a flash game for iPhone using Flash CS5, Everything runs smoothly when creating swf via Ctrl+Enter. But when I am attaching .p12 and provisioning profile files and publish the FLA for generating .ipa there is an error thrown by the compiler that is:
"Incorrect number of arguments, Expected no more than 0" private static function closestVertexOnOBB(p:Vector, r:RectangleParticle):Vector { var d:Vector = p.minus(r.samp); var q:Vector= new Vector(r.samp.x, r.samp.y); for (var i:int = 0; i < 2; i++) { [Code] .....
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.
I am trying to snap 2 vector points together but for some reason its moving the entire object instead of the point. I am trying to follow instructions in a book and the book shows that it is using the solid (filled) selection tool and it has the magnet turned on for snap options. It shows I am suppose to click where the (right triangle) appears beside the mouse arrow and then snap. but it keeps moving the entire Object even with the (right triangle) appear beside the mouse arrow. what could I be doing wrong ??
Because of the inability to create Vectors dynamically, I'm forced to create one with a very primitive type, i.e. Object: var list:Vector.<Object> = new Vector.<Object>(); I'm assuming that Vector gains its power from being typed as closely as possible, rather than the above, but I may be wrong and there are in-fact still gains when using the above in place of a normal Array or Object:
