ActionScript 3.0 :: Making An Argument Of Type Function Optional
May 16, 2009
Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;
var animTween:Tween;
[Code].....
I have figured out the following: Well, as you see the function moveStuff accepts three arguments, namely:
objectdurationeasingWhen easing has a default value, I get an error. But if it doesn't have a default value, then it works fine, the code would look like so then:
Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;
var animTween:Tween;

In ActionScript 3 you can declare optional parameters like this:function (i:int = 0, s:String = "", o:Object = null):void { }So you can check if the user passed parameters s and o because you can test against the empty string or the null object if(s && o)...But how do you allow an int to be truly optional? What if all values for i are valid, including 0, negative and positive integers? And what if you want to enforce integer (not use Number?)what's the best practice here? the (...) rest may work but then you can't enforce a certain number of parameters at runtime, nor can you make for useful code completion?

I want to guess the type of every argument from an anonymous function, something like mapping a class with reflection but just for a function, something like...
public function guessMyArgumentType(f:Function):void {
for each (argument:* in f.arguments) {
trace(typeof(argument));

I want to add things to the display list, some will have event listeners and some not. Is it possible to make an argument optional so it doesn't throw an error if it's not there when calling the function?

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.

I have a movie clip in my library linked with a class name "MyClass", and I am trying to do something like this in Actionscript 3:
function createbtn(bclass:Class):void{
var addB:bclass = new bclass();
addChild(addB);
}
creatbtn(MyClass);
But, I get this error: "1046: Type was not found or was not a compile-time constant: bclass."

I'm using FlashBuilder 4 beta2. My base class has a function foo():
protected function foo(s:String, z:String=null): void{}
Literally "foo" so that there's no chance I'm stepping on a built-in method. I am getting an
"Incompatible override" error when attempting to override the method in a subclass:
override protected function foo(s:String, z:String=null): void{}
Does the optional parameter do something "behind the scenes" that makes it illegal to override the method?

I have a function and it accepts an argument, it can be a MovieClip or an Array. How can I determine what the type is of the argument? I did an attempt, but it didn't work, my code currently looks like so:
Code:
var peopleArray:Array = new Array("Alfred", "Bob", "Casper", "David");
function myFunction (givenArray:Object) {
if (givenArray.dataType == Array) {
trace ("This is an array");
// do stuff where an array is needed

Code:
for (var i:int = 0; i < menuArray.length; i++) {
var currentIndex:MovieClip = this["menuButton" + i]
currentIndex.menuButtonTxt.text = menuArray[i];

So when I did this the problem that I am having is that it throws an error at compile time. 1067: Implicit coercion of a value of type void to an unrelated type Function.

I want to write a function which has 2 dimensional array as one of its arguments
_global.getList = function ( type:Number, list[]:Array )
This is giving syntax error, if I do
_global.getList = function ( type:Number, list:Array )
Then there is no error, but then, list is now, single dimensional array, which I don't want. Whats the correct syntax to write it as two dimensional array?

I have recently moved from AS2 to AS3 and I am finding the transition fairly easy, however I do have a few questions, some of which may not have been possible with AS2 but I would like to achieve them in AS3
1. Is it possible to pass the name of a class as an argument in a function and then use it to create a new instance. e.g [code]
2. Carrying on from the previous question, if a class can infact be passed, can I specifying a variable type for the argument so that only classes and not instances will be accepted?
3. I have three class files that all inherit some functions and variable from another class called Ship. Is it possible to specifying a variable type so that the variable can only hold instances of classes that are inherited from the Ship class?
