Actionscript 3 :: Dynamic Class That Only Accepts A Given Type?
Aug 18, 2011
Is it possible to make a dynamic class in AS3 only accept dynamically created properties if they're a given type?For example, I may only want Sprites to be allowed. So take this quick example class:
public dynamic class Test extends Object{}
And a few quick lines to get an idea of what I mean:
var test:Test = new Test();
test.something = 32; // error
test.something = "party hats"; // error
test.something = new Sprte(); // works
Maybe using the proxy class/namespsace there's a way to manipulate whatever is run when creating variables dynamically?
I constantly get:Implicit coercion of a value of type Class to an unrelated type lash.display.BitmapData.var ba:ByteArray = jpg.encode(BitmapData);This is my code from where it tells me it's wrong"
ActionScript Code: var jpg:JPEGEncoder = new JPEGEncoder(); var ba:ByteArray = jpg.encode(BitmapData);
Basically plots a dot wherever you click. Getting the error 1067: Implicit coercion of a value of type Class to an unrelated type Function.
package { import flash.display.MovieClip; import flash.events.MouseEvent; public class particle extends MovieClip { //private var _xmouse:Number; //private var _ymouse:Number; private var mc1:MovieClip = new MovieClip(); private var mc2:MovieClip = new MovieClip(); private var mc3:MovieClip = new[code].....
I don't understand why this script doesn't work. I am new to Action Script 3.0 and I watched this incomplete video on youtube. -- [URL] and I got the fails below.
So for instance, I've got three .as files called 'Helicopter.as, Game.as, Blue.as' and I also have a .fla file called Helicopter.fla (These files are all suppose to link together, to make the helicopter game) . In the Game.as file, I have the following;
[Code]....
Flash doesn't recognise the original Helicopter symbol (in the Helicopter.fla file, because I deleted it). But I want the system to detect the 'circle' drawn using API (In the Helicopter.as file). And I have no idea how to how to name the API drawn circle 'Helicopter', thus I'm getting an error. So how do I name the API circle to 'Helicopter', so the Game.as file recognises it.
Need a code that only accepts numbers. Upon inputting, the code must check if it is number, if not, it must remove the entered key or not enter it at all
Is there a way to detect when the user accepts the Privacy Pop-up?
Basically, I'm using the microphone to record a voice message. I'd like to start a countdown timer that tells the user how much time they have to record their voice.
I start the countdown timer on the same event that I call nsPublish.attachAudio(microphone), and the countdown starts immediately, even though the user sees the privacy pop-up.
I created an flv video player using Flash Builder 4. This "BasicVideoPlayer" project is compiled into a SWC that will be eventually be used to create other video players that extend the functionality. One of the features is a view that appears when the video has finished playing that displays a "Play Again" button. This "Play Again" view has its own class, "BasicPlayAgain", that accepts a graphic asset that is exported from a .fla file that contains all of the graphic/UI assets.
In my new project, "EnhancedVideoPlayer", I'm using the BasicVideoPlayer SWC as a library to create a new video player that will add more functionality to the "Play Again" view; specifically it will add more buttons to that view.The EnhancedVideoPlayer uses a default class that extends the BasicVideoPlayer class. The BasicVideoPlayer class has a member called "playAgainScreen" whose type is BasicPlayAgain. The EnhancedVideoPlayer needs to override the playAgain member and recast it as EnhancedPlayAgain so it can control the new buttons properly.
I realize this is kind of an odd issue, but I am wondering if there's any way to get Flash to allow me to access a class's static functions using a class variable that points to the class. Example:I create a class called FooClass that has a static function named fooI then create a variable of type Class that points to it
Code: var class:Class = Class(getDefinitionByName("FooClass")); However, when I try to call foo() using the variable, it errors saying the function
I'm working on an accordion component and I was thinking that it'd be cool if I could write a very basic one and then set it up so that it would be possible to pass in any kind of container class and child class so long as they subclassed a particular parent or implemented an interface (haven't really gotten that far yet).
What I've noticed though is that I can't setup a default class for my constructor parameter. For example I'd like to do this:
Code: public function DropDownList(containerClass:Class = ContainerSprite, childClass:Class = ChildSprite) However it gives me the following error: 1047: Parameter initializer unknown or is not a compile-time constant.
I am making a ball move from left to right and back. but when I rollover twice quickly, it also accepts the second rollover command. I would like it to accept that second rollover only when the first one is finished. I mean, I want the first to be finished before it accepts another rollover.I know it is simple to solve this with a tween using frames instead of as, but I was wondering if someone knows how to adapt the script.
I have an application which receives dynamic XML data from a server. The structure of the XML is dynamic and the tags/attribute names cannot be predicted. NO row items can be hardcoded. The data is coming back from a database (imagine columns and rows), and the type of the data is known on the server side. The following is just an example, an only shows the structure of how the data comes back.
I'm parsing XML file and draw some objects. Each object has it's own class which name is stored in another XML. I also have some .as files with those classes, f.ex[code]...
I'm not shure how to do this. Is it possible to give dynamic names to the types like, khm obj:{classname}=new {classname}?
without having to make my movieclip (from a swc) a global variableThe code works perfectly, but i'm guessing it's redflagging it because it's not a waterproof method.
i want to essentially classify a simple function in it's own .as file. the function compares integers. but i don't know how to call the class and receive a boolean return.
here's my class
package { public class CompareInts {
[Code]....
so now i'd like to write something like this:
if (CompareInts(1, 5) == true). or output 'true' by writing trace(CompareInts(1, 5));
I have a main application(app.swf) which loads a module(profiles.swf) and the profiles module loads another module(member_profile.swf). In member_profile I get member data from the server side where an object of type Member is returned. The object returned contains an array called Jobs holding objects of type MemberJob. In the member_profile module there's a function that takes a parameter of type MemberJob to display the job details. I have a loop that goes through the array returned and calls the function for each array item like this:
for(i = 0; i < member.Jobs.length; i++) addJob(member.Jobs[i]);
I am getting an error at the addJob line: Type Coercion failed: cannot convert components.classes::MemberJob@19107d81 to components.classes.MemberJob.
And I receive this error always on the second loading of the member_profile module. I mean this module gets loaded when I click a member's name from the profiles module which passes this name as the parameter for the sub module to load the profile of that member including his jobs. So if I chose to see the profile of member "X" the profile is loaded without any errors but if I then click on member "Y" (which causes the sub module to be reloaded with the new parameter) then I get the type coercion error. And if I did the opposite click on "Y" first then "X" the same happens, error in the second load.
I have a class which deals with a lot of visuals, which essentially are movieclips. So I have around 50 privately declared movieclips in the class. Would it be a good idea to put them in a dictionary and retrieve them by their name (as key) , put them in an array or just leave them as they are?
My issue is the visual look of my class right now with that many private members, looks like a mess visually.
ve faced a problem. I have a super class called "Plane" which has subclasses called "Fighter" and "Bomber". each of these subclasses have a bullet type "Cannon" and "Bomb"Now I want the to send a reference of the bullet type to the super class, because bullet creation is handled there and I want to let the super class know which bullet type to create.Ofcourse I could pass a string, I just ant to know if there is a better way, like storing a class type in a variable?
I'm working on a game where I'm adding a symbol (an enemy unit) from the Library via addChild() to an instance on the Stage. The symbol has Linkage/Class enabled so I can stick stat variables directly on it for easy access.The problem is that I want to use the same name for enemies (like en0, en1) in different areas, but if I try to removeChild(), I get Error 1067: Implicit coercion of type Class to type DisplayObject.
Coming from a Delphi background, I am used to be able to have class references/pointers of a specific superclass, example: #!pas var niceVar: class of TClassOne; // Delphi style badVar: class; // Only? allowed AS3 style to the best of my knowledge begin niceVar := x; badVar := x; niceVar.staticMethodSpecificToTClassOne; TClassOne(badVar).staticMethodSpecificToTClassOne; end;
What this means is that I don't have to cast my variables to a specific class; they are of the correct Class beforehand. This also means that compile-time checking can be performed to make sure proper members are being accessed and I don't have to check that niceVar is in fact of class TClassOne if niceVar was passed to a method. [Code] .....
So just like a variable storing an object can be for a specific type and only objects of that class or subclasses of it are accepted, so to does "class of AClass" allow for variables of a specific class to be limited to references to a certain class or those inherited from it. I hope that makes sense somehow; I don't know of specific nomenclature for the whole "class of SuperClass" thing. So I'd like to do the same in AS3 as having variables/properties/parameters of type Class does not cut the mustard; its kind of like having all object variables/properties/parameters simply being Object instead of their proper, specific type.
What I'd like to be able to do public function set recordClass(aRecordClass: TRecordClass): void { _recordInstance = new aRecordClass(this); // Compiler will know that I am creating a TRecord }
