ActionScript 3.0 :: Get Vector To Contain Elements Of Different Types?
Dec 31, 2010
The AS3 Reference says that...
ActionScript Code:
var v:Vector.<DisplayObject> = new Vector.<Sprite>();
...won't compile because the object's base type isn't the same as the variable's declared base type (even though Sprite is a subclass of DisplayObject)But I tried the following which compiles fine:
ActionScript Code:
var v:Vector.<Sprite> = new Vector.<Sprite>();
var a:Sprite = new Sprite();
var b:MovieClip = new MovieClip();
I'm trying to use Vector. in a Flash Professional Project, Person being a custom class. Eclipse keep saying it cannot find the type in brackets, even if I try with basic types like int or String[code]...
The way I'm doing this is by giving the function metadata which sort of maps the JSON data properties to these data properties and their types, using reflection.So, I have a JSON object that might look something like this:
I have function that's used to transfer elements from one vector to another. The problem is that I need to use this function to transfer data from multiple pairs of vector with each pair having a different data type. I tried this but it came up with an error.
ActionScript Code: function addToVector(dataType:Class, vect:Vector.<dataType>, baseVect:Vector.<dataType>):void { for (var i:int = 0, l:int = vect.length; i < l; i++) baseVect.push(vect[i]); }
I've also tried this, but then flex says it doesn't recognize the vector class. ActionScript Code: function addToVector(vect:Vector.<*>, baseVect:Vector.<*>):void { for (var i:int = 0, l:int = vect.length; i < l; i++) baseVect.push(vect[i]); }
This failed too ActionScript Code: function addToVector(vect:Vector.<Object>, baseVect:Vector.<Object>):void { for (var i:int = 0, l:int = vect.length; i < l; i++) baseVect.push(vect[i]); }
I'm using a Vector structure in ActionScript 3 to store references to a custom class. My Vector is fixed length for performance reasons, and also because it needs to map 1:1 to another data structure.
I'm trying to figure out how I "remove" an element from this fixed list. I don't want the length of the Vector to change, I just want the value of that element to be "null". Or more specifically, when I test for the truth of that element (eg: if (myVector[index]) { // do something... }), I want that test to fail for that element, since it's "empty".
I've been developing Flash applications for several years, and here's something I've always wondered about.
I try to be as careful as possible about minimizing the amount of "overhead" that my application uses. (By overhead, I generally mean RAM, cpu processing effort, downloaded data, etc.) My goal is to consume as little of the user's PC resources as possible.
[Code]...
I circumstances matter - a few KB of "page weight" on Amazon.com or Twitter.com matter a lot more than on a site that gets a few hundred visitors a month. But in general, are there good tools to measure this type of thing?
Code: public function foo(bar1:int, bar2:uint, bar3:String, bar4:Boolean):void{}
What I want is to have the different types of data represented by custom named types which are essentially representing the original data types. I other word, I would like to proxy the data types and have a valid function as following:
Code: public function foo(bar1:PAR_Bar1, bar2:PAR_Bar2, bar3:PAR_Bar3, bar4:PAR_Bar4):void{}
so PAR_Bar1 would proxy the `int` data type, PAR_Bar2 would proxy the `uint` data type, so on and so forth.
The reason I need this is because I'm using a debugger with a GUI that can run methods and allows changing function parameter values in real-time, the issue is that the debugger can't tell me what parameter I'm changing, it only displays the data type of a parameter. So if I need to change 10 different parameters all of type int, the debuggers display all of them as int and not by their names.
I think that if I use proxy types I can easily differentiate between parameters.
So, my question: Is it possible to proxy data types? I mean map specific data types to custom data types that would represent the base data types?
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 need to import a bunch of vector work from Photoshop into Flash. Is there a trick to it. So far, on import, it's converting the layer styles into black.
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>.
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 made a .as Class where some graphical elements are spawned into the stage. However, the Flash (.fla) have some internal graphics that are supposed to be over the graphical elements spawned from the custom class.I tried to make another layer over the layer where the as3 Class is being called, but unfortunately it doesn't do anything, the graphic from the .as still appearing over the internal .fla graphics.
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 was looking for the difference between the different content types in Flash CS3/CS4 - Browser/Screen Saver/Application etc - especially it's capabilities and limitations. Of interest are Standalone player and Application.
Types like Movieclip , String, Object act as references when declared and defined, while types like int, Number are primitives. Why such difference has been made. Why not all of them can be primitives ?
I've been working on a cute game and I've hit a bit of a wall
It's a shooting gallery game and I want to add multiple target types (so far this has been easy) but I want to game to randomly bring them up as you play. There are four possible target spots and seven possible targets:
In the past I embedded several (with makers permission) youtube clips into a html web page (with the file stored on my server - mainly because I think it looks nicer). It worked fine. Now these were the old plain .flv low quality ones. But now I am trying to embed the newer higher quality youtube version, again, with the file stored on my server, and the embed code I used previously doesn't work. Now the new higher quality file is still called flv but it has a codec: mp4a
My old coding: <object type="application/x-shockwave-flash" width="704" height="546" wmode="transparent" data="mediaplayer.swf?file=xxx.flv&autoStart=false "> <param name="movie" value="mediaplayer.swf?file=xxx.flv&autoStart=fals e" /> <param name="wmode" value="transparent" /> </object>
A gentleman doing the sound track for the video I want to do on Flash has asked me what audio files Flash will handle? I have looked at Adobe and Macromedia and many other Flash websites and, of course, Flash itself, and cannot find any enumeration of what video files Flash handles, much less any mention of what audio files.
i have a tree of nodes that i dont want some type of nodes to appear in the tree, i can check the data on tree item renderer for each specific node type, so i have one type that i dont want it to be shown as tree node, like it doesn't exist.
I've been developing a framework for ActionScript 3 and have come across a peculiar scenario where I want a method to be able to return either an AvFrameworkObject or an Array containing multiple instances of AvFrameworkObject.[code]...
public function foo(bar1:int, bar2:uint, bar3:String, bar4:Boolean):void{}
What I want is to have the different types of data represented by custom named types which are essentially representing the original data types. In other words, I would like to proxy the data types and have a valid function as following[code]...
