I'm working on a very simple dependency injector, reflecting on a types constructor parameters.But when ever I use the describeType on my custom classes, all I get in the constructor packet of the returned XML is something like this:
<constructor>
<parameter index="1" type="*" optional="true"/>
</constructor>
[code].....
is it possible to obtain the instance name of a class from the class without having to manually pass the instance name as a string parameter to the class constructor?
//Create New SizeClass
var big:SizeClass = new SizeClass();
//-------------
[Code]....
I have the Class and the parameters of its contructor as an object. What I need to do is a function that returns an instance of this class, passing this parameters to the constructor.
This is the code:
Some random and unmodifiable class:
public Foo {
public function Foo(a:int, b:String) {
// constructor
}
}
And some function (in some another class):
function bar(params:Object):* {
var baz:Foo = new Foo(params.a, params.b);
return baz;
}
What I need to do is make this function generic, without pass params as parameter to Foo constructor because I can't modify it. Something like:
function bar2(clazz:Class, params:Object):* {
var baz:* = new clazz(/*some magic way to transform params in comma separated parameters*/);
return baz;
}
I am working on a side-scrolling platformer game. Because of this, I have a class that acts as a floor. I also have a class representing enemies. I am having problems with passing a parameter to a custom class' constructor. The class (SkullDemon.as) extends MovieClip. I am trying to pass an instance (called "floorL1") of a customer class called "FloorLevel1." "FloorLevel1" also extends MovieClip (I do not have a written .as file for "FloorLevel1"; I just exported the floor MovieClip to that class).
I am trying to pass an instance of "FloorLevel1" so that the "SkullDemon" object can land on the floor just like in a platformer. My main class is called "TME2_Main." This is the class from which I try to pass the "floorL1" instance to the "SkullDemon" class. This is how I try to create a Skull Demon instance and pass "floorL1" to its constructor:
[Code]...
What am I doing wrong here? I have spent a while looking for solutions (including moving code outside of TME2_Main's constructor),
I want to serialize ThugtrisShapes' children (heritage/polymorphism) but his children like Right_LShape take constructor parameters,i have to assign it a default value (in my case null because they receive an Array type), but i get this error even when implementing IExternalizable.
Take Note: IForm extends IExternalizable.
here is a link i found about it but it still does not work...[URL]
Code:
public class ThugtrisShapes extends Sprite implements IForm
{
var squares_:Array;
var numsquares_:int=MAX_SQUARES;

I know that not all class' can be cloned , but cloning is an important aspect of OO programming.... There should be a solution for my problem,besides taking the parameter out of the constructor and add a setter.
Let us assume I have classes "Main", "Sub1" and "Sub2". I also have interface "Inter".[code] Basically, I want the constructor function of any class implementing "Inter" to take the same parameters, and thus avoid initialization errors. (So as that the code above gives a compiler error) With any other function,[code]But As the constructor name differs from function to function, I cannot do this.
View 4 RepliesI just posted a message asking how to call a method from the constructor which has the parameters e: Event. I mistakenly ticked that post as answered when in reality it isnt. I was told I could add = null in the parameter of the function to make it work, like this:

So I usually use an object in the constructor to receive the parameters like new Class({param1:00,param2:0099,etc).To be able to access those parameters from other functions inside the class I create an object, and copy it:
Code:
public class MyClass {
var params = {};
public function MyClass(p){

I've got a function wich can accept a varible number of parameter with a rest operator. I want create an object passing the argument collected with the rest operator directly to a constructor without create an object and call an initializing function and without passing the entire array but the parameters ah I do with apply() function.
[Code]...
When using ObjectUtil.copy() on my object, I get the following error
Argument count mismatch on foo.bar::MyObject(). Expected 1, got 0.
MyObject's constructor takes in one parameter. Is there a way for me to clone, or copy it?
Is it possible to create a class instance dynamically and specifiy the constructor parameters dynamically?
So for example, imagine I have a class 'TestClass' which as constructor takes two parameters, (Array, int)[code]...
How do I call class constructor functions with indefinite number of arguments?
For example:(this piece of code doesnt serve any purpose, just to demonstrate an example)I wish to create a new class Foo with the parameters bar1, bar2, bar3, bar4.
[Code]...
I know I can create instances from a string like this:
var classFromClassPath:Class = getDefinitionByName(classPath) as Class;
var instance:Object = new classFromClassPath()
I know I can call some function with a parameter array like this
var x:Function = someFunction;
x.apply(null,args);
But does anyone know if I can pass parameters like that when I construct a class?
i've added this reflection class [URL] to this simple .fla file, but i can't see any reflection [URL]
View 2 RepliesThere is a library component represented by Class A. But constructor of this class requires some parameters. When the component needs to be added dynamically, it's fine because of code :
var abc:A = new A(param1,param2)
But what if my movieclip is already present on the stage. I notice it gives out error, that the parameters are null.
Is their any way to insert constructor parameters for movieclips already on stage.
I am new to actionscript 3 and I wanted to know if anyone could direct me to some websites (Tutorials) which can help me create a gallery like the one in the link but using AS3. Any help would be really appricated, I am not asking for the code just tutorials I can use to create someting very similar to it. [URL]...

View 1 RepliesI have been looking at how to reflect a point in a line, and found this question which seems to do the trick, giving this formula to calculate the reflected point:
Given (x,y) and a line y = ax + c we want the point (x', y') reflected on the line.
Set d:= (x + (y - c)*a)/(1 + a^2)
Then x' = 2*d - x
and y' = 2*d*a - y + 2c
However there are two problems with this implementation for my needs:
My line is not described in the form y = ax + c (so I'd have to translate it, which is easy to do, but it means the process is slower). What if a is infinity ie. a vertical line?
Is there a simple way to calculate (x', y'), the reflection of point (x, y) in a line, where the line is described by the two points (x1, y1) and (x2, y2)?
Edit:
I've found a formula which does this, but it seems as though it does not work with lines that look like they have equation y = x.
Here it is in actionscript:
public static function reflect(p:Point, l:Line):Point
{
// (l.sx, l.sy) = start of line

i am using 2 instances of an flv, and as you would expect they arent sync'd.so how do i 'clone' an flv in AS3 so that they are exactly the same?i have seen an example, but it was AS2, i am working with AS3, cs4..[URL]
View 5 RepliesSo I followed the 3D Carousel tutorial, the first part of it and the coding worked fine, but the reflection is not working properly. I used a .PSD file and followed the instructions step by step. I added the action script code in the end, but when I take a look at the preview, the reflection image is displayed just like the original picture. Is the .PSD format a problem?

View 3 Repliesi'm trying to create a "reflection" to scrolling text.i'm using a nice little scroller code that works very well on it's own. i thought just duplicating the movie clip and mirroring it would do the trick, but instead only the "reflection" bit is moving up and down, the rest of the items stay put.
i thought it might be a matter of changing instance names, but then the "reflection" is the same object, just mirrored vertically, so i'm not sure how one should go about doing this...i'm attaching both the FLA and SWF files...
I have an image and I want it to have a reflection and to apply an effect onMouseOver so that image bounces (like a rubber ball) until it stops.I found this example (http:url]....)that does exactly what i want (except I want it to bounce just one time per mouse over), but this is for Flex and I cant manage to translate it to Flash.

var thumb:Loader;

I am trying to provide a reflection for the images(movieclips) that I loaded on the stage. For this purpose I am using a reflection class. The class can be used with action script 2. the reflection is working finely. Also after loading the image or movieclip, I tried to give tweening for that image or movieclips. Thus also it works finely. The reflection of that also moves along with the actual image. The problem comes with the resizing the actual image. If I resize the actual image, the reflection would not be seen under the actual image.Can anybody know why it may happening like that. After searching for a long time, I got this class.But unfortunately, the reflection would not be working when the image or moviclip resizes.
View 8 RepliesI'm trying to create an image reflection at runtime, using this code I found on the WEB. It all seems to work fine as long as I'm loading an image from the local drive, but when I try loading an image from a remote server, the reflection no longer appears.[code]
View 13 RepliesIs there a way to "reflect on" static members of an ActionScript object (get all the static properties/methods of that type programmatically)?
Why is that flash.utils.describeType(*) can only show non-static members?
What I've done so far is using your mouse you (click & release) you shoot a ball off in that direction using radians. Now what I'd like to happen is when the ball hits the wall it bounces off in it's reflection angle. Eg. if the ball hits the right-hand-side wall travelling at in a radians of -0.65 it should bounce back in the radians of about -2.5
View 3 RepliesI have a image loaded in a sprite, the image is from a remote location [URL]. Once the image is loaded in the Loader Object i then want to create a reflection of the sprite that contains the image. Now this works when i run the application in flash IDE but when i embed this flash application inside a HTML page the reflection images do not work. Why is this, the code is below.
