I'm creating a slideshow where each slide can have:- a video or a still- 1 audio track or many (up to 3)- 1 button or many (up to 3)I was thinking that each slide can be it's own object, and then I would pass the video, audio, buttons, etc., into it as parameters:

Im coding in AS3, and i want to make a class that will recieve optional parameters, but i dont know how to identify these parameters as optional.
I tried writing
Code:
public function mydate([language:String]):void{
like Adobe identifies optional parameters, but it doesnt work
I want to create some functions similar to how GreenSock's tweening class works.With the optional parameters by name in brackets. {}[code]I get this error: "Parameter initializer unknown or is not a compile-time constant."Pretty sure it's the "Parameter initializer unknown", but I don't know what to do about it.
View 8 RepliesI have a class that represents a turret in the center of my screen.When I hold down SPACE, I want it to create a "bullet"-object that moves in the direction of the turrets cannon, every frame the SPACE key is held down. I am having problems with this cause I am getting this error when I am trying to create the object:
Error #1009: Cannot access a property or method of a null object reference.
This is where the error occurs:
ActionScript Code:
public function chaingun(x_:int, y_:int, rot:int, cd:Number, spd:Number, sprd:Number, life:Number) {
this.Cooldown = cd;
this.Speed = spd;
[code]....
PS: What happens is that when I press the SPACE key, the "turret" class event handler runs the function "Shoot_Chaingun" and that function creates a new Chaingun-object (which actually is a bullet), that inherits the x, y, and rotation of the turret, along with some additional varaibles, including lifetime. Then upon creation, I use "addChild(this)" to add it to the main stage, and "removeChild(this)" once it's lifetime is up.
EDIT: And also, I just realized I don't have a MovieClip linked to this chaingun class. How do I make sure that every time a chaingun object is made, the MovieClip is also loaded?
I want to create a simple component in as3, cs4. There are 2 problems I cant solve:
1.)I can't get the default parameters "loaded" in the class for the component so lets say if I have w = 10 in the parameters how can I refer to it in the code?
2.) How can I get the tool with which I can set which corner of the component should stay the same : it looks like this in the default
flash button component

I have created a file called Config.as, in it are getter and setter methods that define variables that I need to reference throughout my system.
I have obviously made a mistake as I tried to access a variable in two files as indicated in a demo below:
Code:
package {
import Config;
public class TestOne {
[Code].....
It seems quite clear to me that I have created two instance of the Config class and that is why in class TestTwo the trace statement doesn't return "hello world". Is there a common coding practice to access the same variable with multiple classes?
How do I make some parameters of a function optional?
For example in the function below, how do I make para3 optional?
function someFunction(para1:int, para2:int, para3:String){
}
I have this function:
Code:
MovieClip.prototype.changeColor = function(mode, kl, kh, rl, rh, gl, gh, bl, bh) {
}
How can I make all parameters optional except the first one?
Is there a way to generate an instance of a class that implements an interface based on the name of the class?
I am trying:
var ClassReference:Object = getDefinitionByName("movement.OuterSpaceMovement") as IMovement;
var m:IMovement = new ClassReference as IMovement;
trace("startup..." + m);
-But I am getting an error message ReferenceError: Error #1065 (OuterSpaceMovement) not defined.
I have several classes that implement the same interface (IMovement) but I need to be able to generate new instances of these classes and then pass these instances as a datatype (IMovement datatype) to other classes...
So then I tried:
var ClassReference:Class = getDefinitionByName("OuterSpaceMovement") as Class;
var m:IMovement = new ClassReference() as IMovement;
and this doesn't seem to work...but the following
var m:IMovement = new OuterSpaceMovement();
I'm trying to create a new instance of a MovieClip when the original one has been used. Would sound easy enough. Just use: var
instanceName:ClassName = new ClassName();
the class name/mc in the library im trying to duplicate is MCg1 so
var instanceName:MCg1 = new MCg1(); right?
However, the particular object in the library i'm trying to duplicate has a base class that is an external class file (just to control it's drag drop functionality)... i.e baseclass is not set to the standard flash.display.MovieClip, or whatever the case maybe. So i end out with a: TypeError: Error #1009: Cannot access a property or method of a null object reference.
quick question:Is there a better way to do this?

how i can pass parameters to an instance of a class using the Object.registerClass method. It seems i can only put the name of the class but no extra parameters.
View 3 RepliesIn Flash CSn/AS3 you associate a Main class with a flash file which when loaded in the flash player "automatically creates an instance of the program's main class."I'd like to know how to pass arguments to the main class, since you don't write it yourself (you put its name in the Document textfield in the IDE).

So I have a movieclip that I want to play nice with my class file. So I set the linkage and all that and it works. But, my initialization function gets called with no parameters, because I have not set any. How do I do that with this method?
I've tried something like:
Code:
import tab;
tab1_mc = new tab("left", 5, 55, "testclip.swf", 0);
And that sets the parameters, but not before the linkage on the MovieClip fires. how to get the best of both worlds?
I am wanted to know how can i pass a parameter to the function which I'm calling using Delegate class. I know to pass params having static values such as true / false or a static string "hello".
Code:
var myFunc:Function = btn.onRelease = Delegate.create(tihs, releaseHandler);
myFunc.str = "hello";
function releaseHandler()
[code]....
Here str can be retrieved as 'arguments.caller.str' inside the function.But in case i want to pass the reference of the 'btn' button. Then how can i do this ?
I've got a main.as that loads SWF to the stage. the loaded SWF seppoused to pass a link to the main.as and trigger a javascript function to popUp that photo from that link.
I know there are two ways:
((root as MovieClip).parent.parent as Object).somefunction(parameters);
and to dispatch an event. inorder to pass parameters throug the event i need to extend it with another class.
isnt the (root as... ) more efficient if all i need is to pass a link?
I'm unsuccessfully attempting to instantiate a reference of a class that is passed as a parameter to another class. In this example there are 3 classes:
MainClass, Canvas, MyCircle
From the MainClass I am creating an instance of Canvas, which is passed a class reference of MyCircle as I want to create instances of MyCircle from within Canvas. However, the MyCircle constructor contains required parameters that are created from within Canvas. How can I pass and instantiate a class reference with required parameters?

I'm having some problems importing a class, the message that Flash gives me is this; The class being compiled, 'ImageLoader', does not match the class that was imported, '[URL]'. The only line of code in my flash movie is this: import com.martijndevisser.*; And yes, the class is in that folder The class is from here: [URL] I've used the class before and it works fine, I just dont know what to do?
View 4 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 have a problem when making flash applications with more than one frame that has symbols placed on it in that I can't declare all of the event listeners for the objects at the same time and I have found that even if I put them all on the first frame, add the event listeners, then click through to the next frame then the buttons won't work on that frame.
Does anyone have any idea how I could solve this? I did consider myself a fairly competent AS3 programmer until I realised I had no idea how to handle this sort of thing. Solved: I initialised the clips from my external class and then addChild'd and removeChild'd them as I needed to and placed their x and y on addChilding.
I have a "format" method that works in a similar manner to the C# String.Format method, with the following signature:

I want to create a rectangular box and add it to the stage. Easy enough.
At the moment I create custom classes and attach them to movie clips in the library via linkage, but in my example there is nothing to attach it to as it does not exist. How can I create a "generating class" like this?
I just want to call it with a call like
createRectangle() or possibly have some parameters createRectangle("200", "400")
Version: Flash CS4, AS3 is it possible to turn a given sprite into a Class with a given string as its name? The resulting class should then be available under that name in the current domain's definitions.ie.
