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'm revisiting some old code that filters XML, but this could easily apply to the parameters of a method (the way I'm using it, it essentially is). This is a problem I feel like I run into a lot and don't know a good way around this. So the problem is that I've got 3 arguments. They're all optional. I want to see which ones are presents and test if their values based on which ones are present (sorted according to likelihood):

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){
}
lets say i define a function...
function myFunc(para1, para2, para3){
blah.. blah..
}
but i want para3 to be an optional parameter... can i do it..?
example..i will either use myFunc(var1, var2); or myFunc(var1, var2, var3); when calling myFunc function...
im trying to pass in an optional argument into a function. The datatype of this needs to be an object... however, im not getting very far. I know i can do this....

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'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?
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:

I'm designing a game that uses this function;
function moveBars(Bl:Number,Gr:Number,Or:Number,Ye:Number)
{
blueBar_mc.scaleX += Bl;
greenBar_mc.scaleX += Gr;
orangeBar_mc.scaleX += Or;
yellowBar_mc.scaleX += Ye;
}
When moveBars is called, the length of the 4 colored bars change to indicate how the player is doing in different areas of the game, like so; moveBars(.1,-.2,.3,-.1)
My problem; I need to store the moveBars parameter arguments in XML like so;
<myArgs> .1,-.2,.3,-.1 </myArgs>
But I can't find the way to get those 4 numbers into the moveBars parameters from the XML doc. Is there a way to do this?
I have a component that I hand over a function
public var func : Function;
Now the function is a function that has parameters in its signature
public function myFunction(s : String) : void {
doSomething(s);
}
from my component I can call the function with
func.call();
how to invoke the function with its parameters?
I have a movie clip that contains several movie clips, only one of which should be shown at a time. Which one is shown, depends on what buttons the user selects.Having trouble with the syntax for passing the argument in a button to the function that controls the tweening of the clips. (When I hard code the references into the function, it works, so I know the basic function is ok).There's a clip called 'slide1_mc' which contains various MC's to be shown based on user selection (in this case, using 'system' clip as the first one already showing). Here's the code in the parent clip of that item:
Code:
var currSection = slide1_mc.system_mc;
function changeSection(newSection):Void {
TweenLite.to(currSection,.3,{_yscale:200, _xscale:200, _alpha:0});
[code]....
Here's one of serveral buttons that will control the content to be seen:
The code in the button is:
Code:
var changer = slide1_mc.software_mc;
smallButton.onPress = function() {
_parent.changeSection(changer);
};
So - the initial part of my function works so I know my 'external' initializing of "currSection" is working (that clip is zooming/fading out)... but then the clip that I want to fade in isn't doing anything.

View 9 RepliesLet's say I have a function that accepts a function and some arguments as parameters. Something like:
ActionScript Code:
function myFunction(func:Function,args:Array):Void{
// do something awesome here

How would I go about calling this function with the arguments in args? It's pretty simple to call a function without any arguments, but calling it with them..
As an example:
ActionScript Code:
// I'd like this call
myFunction(trace,["Hello world!"]);

I have a main class that is running an external sub class which loads my data (loads data via flash remoting on a ColdFusion server). No problems loading the data; however, I am trying to run a function from the main class on the sub class function onResult. I do not have problems running functions in the sub class in general, only in the responder result function. Problem: My problem is that I can't pass the main class through the function onResult because I get a error with the arguments.Here's what some of the code look likes:
function init(){
myService2.connect("URLgateway");
var responder:Responder = new Responder(onResult, onFault);
