Optional Parameter
How do i program an optional paramater funtion ?
eg. i want to be able to say like Update() OR Update(type)
Will i need to make two functions ?
function Update(){
}
function Update(type:String){
}
or can i just make one ? ( since this will keep code cleaner )

Optional Array As A Parameter
how do you do this? specifically for a class constructor.
this is what i tried:
Code:
public function MyClass(optional_int:int = 0, optional_array:Array = null){}
and:
Code:
public function MyClass(optional_int:int = 0, optional_array:Array = Array(0)){}
but i get compiler errors. so i ended up having to do on of these
Code:
public function MyClass(optional_int:int = 0, ... args){}
this feels wrong... and does provide different functionality than what i'm after (but works to accept an optional Array)
any ideas?

Using Only 1 Optional Parameter In A Class Method
Is it possible to use, say 3rd optional parameter in a built in class method? I'm trying to use the draw method of the Bitmap class with the clipRect parameter only but it says 'type mismatch' probably because I'm not declaring any of the previous optional parameters.
The original method of the bitmap class is the following, and I'm trying to use the bold parameter only:
public draw(source:Object, [matrix:Matrix], [colorTransform:ColorTransform], [blendMode:Object], [clipRect:Rectangle], [smooth:Boolean]) : Void
Any ideas?

Optional Zoom
I am making a 2d duck hunt type game and i am using the mask option to create a zoom effect in the scope/aimer. I have gotten it to work but i am having trouble making it possible for the user to zoom in even more. I try to make it so when the up or down arrows are pressed you zoom in or out. I have gotten the larger picture of the background to increase in size to make it appear as though you are zooming in but i can't get the picture to line up with the normal sized picture. This is the function i am using for the zoom option:
bigbckground is the larger picture that is giving the zoom effect
scope and zoom are the aimer and the maskover it so it can zoom
bigzoom is the variable being used to increase and decrease the zoom effect
bigzoom=0
zoombigbackground = function () {
scope._x = _xmouse;
scope._y = _ymouse;
zoom._x = _xmouse;
zoom._y = _ymouse;
Mouse.hide();
bigbackground._x = (-1)*_xmouse;
//this is aligning it for regular zoom
bigbackground._y = (-1)*_ymouse;
if (Key.isDown(Key.UP)) {
bigzoom += 2;
bigbackground._xscale = bigbackground._xscale*2;
bigbackground._yscale = bigbackground._yscale*2;
bigbackground._x = (-1)*bigzoom*_xmouse;
bigbackground._y = (-1)*bigzoom*_ymouse;
//this is where i have problems with it algining the big picture^
}
if (Key.isDown(Key.DOWN)) {
bigzoom -= 2;
bigbackground._xscale = bigbackground._xscale/2;
bigbackground._yscale = bigbackground._yscale/2;
bigbackground._x = (-1)*bigzoom*_xmouse;
bigbackground._y = (-1)*bigzoom*_ymouse;
}
};
If any can help me please do. THANKS!!

Optional Parameters
Hello,
I have always wondered about optional function parameters.
Lets say i have a function below:
Code:
function cookies (tastes_good:Boolean, is_big:Boolean, amount_of_chips:Number) {
if (tastes_good) {
trace("i taste good");
}
if(is_big) {
trace("i am big");
}
if(isNaN(amount_of_chips)) {
}
if(amount_of_chips == null) {
}
if(amount_of_chips == undefined) {
}
}
which is the proper way of checking if amount_of_chips has been set. Is there a way of saying amount of chips is option right were u pass in the parameters? something like you can with objects:
function cookies (tastes_good:Boolean, is_big:Boolean, {amount_of_chips:Number}) {
or can you set a default number that will get reset if I pass something in:
function cookies (tastes_good:Boolean, is_big:Boolean, amount_of_chips:Number = 0) {

Optional Floating Exponent
Flash outputs 0.0000000000056 as 5.6e-12. I do not want the "optional floating exponent". I want 0.0000000000056. Is it possible?
I ask because I'm making a math game for kids in converting small numbers into scientific notation and I want them to change 0.0000000000056 into 5.6 x 10^-12 manually.

Class With Optional Arguments
I would like to create a class for a project I'm working on. This class would be used for cables that are unplugged and replaced, some of which are tested with a multimeter. The issue is that, if the cable doesn't need to be tested at all, it is possible to simply unplug it then replace it from the unplugged state. Other cables, however, need to have certain pins tested for voltage and thus need to go to what we call the "face" of the cable (the part that plugs into the outlet).
My first thought for a class was to have a couple of optional arguments that would be used to give the appropriate pins needed for a test, if in fact the cable would be tested. But can I make a class with optional arguments?

sendLV = new LoadVars();
for (var i = 0; i<tfArray.length; i++) {
//check fields for entry
if(t[tfArray].text.length<1) {
entry=false;
break;
}
sendLV[tfArray] = t[tfArray].text;
}
if(entry) {
//send email request **CHANGE THIS PHP ADDRESS**
sendLV.sendAndLoad('http://as2.omni1031.com/RepSupport/contact',receiveLV,'_POST');
}else{
//display error message
fieldError();
}
};
receiveLV = new LoadVars();
receiveLV.onLoad = function() {
//do whatever: message sent successfully (thank you + info page or something)
TEMPty_mc._visible = true;
//in this case I've turned off all the text fields and the buttons
for(var i=0;i<tfArray.length;i++) {
t[tfArray]._visible = false;
}
submitBtn.enabled=false;
};
//display error message handling
var fielderror_id:Number;
function fieldError() {
submitBtn._visible = false;
submitBtn.enabled = false;
fielderror_mc._visible = true;
clearInterval(fielderror_id);
fielderror_id=setInterval(this, "time", 3000);
}
function time() {

Having Optional In Function Parameters
How do I go about setting up a function to optionally take a parameter? For example, to call a function like the following
test(1,2,3)
test(1,2,3,4)
Both of these would call the same function, but parameter 4 is optional. I have done this in VB.NET with 'Optional' and I can default the missing parameter. Is this possible in AS?
thanks,

Define Constructor With Optional Parameters
Hi,
I'm creating a class and I'd like to have some optional parameters in my constructor. Can I do this by simply defining parameters and then not passing them if I don't need to, or is there a better, cleaner way to do this.
eg
code:
class FooBar {
FooBar (aMandatory, anOptional) {
trace (aMandatory);
trace (anOptional);
}
}
Then, I'd like to be able to call it either as:
code:
FooGuy = new FooBar ("Happy");
FooGirl = new FooBar ("Happy", "Sad");
This appears to work as I've done it, but I'm wondering if something will break that I'm not seeing right now!

How To Organize Classes For Optional Inclusion?
I have Flash MX 2004. I want to write some actionscript classes that i can import into my Flash projects. I want someone using my classes to be able to choose which class will be used to encode data. Is there a way that my main class (let's call it Service) can choose which file to reference for another class for data encoding? For instance, if I want my Service class to be a communication channel and I want to have it encode data as XML i could choose a class called SerializeXML. If I wanted my data encoded as a PHP object, i would use SerializePHP.
Ideally using my main Service class in your Flash file would not bloat your project unnecessarily by compiling a Serialize class that doesn't get used. For instance if I'm developing my Flash project to speak with a PHP server, there would be no need for SerializeXML and so it would not get included.
Is there some easy way to do this? I'm also hoping to make my class very easy to use so the users don't have to write a ton of code to choose SerializeXML vs. SerializePHP.
I imagine something like this:
Code:
import myService.*
var Service = new myService('server.mydomain.com', blah, blah);
// this line would result in SerializeXML being used for all data objects
// sent across the myService connection
Service.encodingMethod = 'XML';

How To Make Sound Optional In Flash?
I need to edit this flash design. I have not done flash in a very long time and have no clue what to do so I need a simple and step by step explanation. Currently, the flash design starts off with sound and there is an option on the bottom right corner that let's you turn it off. I need it to be the other way around. I need the flash design to start with the sound off and then have the option on the bottom right to turn it on.
How can I do this? Please explain. Thanks!

Create Function With Optional Parameters
Hi there! I have this simple problem...
I want to create a function that has default values for its parameters. I do it like this:
ActionScript Code:
function fn (param1:Number) {
//set the default value
if (!param1) {
param1 = 0
}
//execute the function
trace (param1)
}
I just wondered if there is a more elegant way. Something like:
ActionScript Code:
function fn (param1:Number = 0) {
trace(param1)
}

How To Make A Function With Optional Arguments?
I'm just starting to get into creating my own custom classes. My first experiment is a custom textfield that includes a scrollbar (and necessary behavior).
Right now the constructor function needs the height, width, a textFormat and a string (the actual text). I want to make those all optional with defaults. How would I go about doing that?

Parameter
Hello!
I've just started to work with flash (MX) and I wonder...
How is it with parameters in flash.
If I have four scenes: start,intro,pictures,and music.
When a new visitor enter the site for the first time then I want to have an intro on every page. I have declared a boolean "introfirst=true" ---> if(introfirst){I play my intro and then setting the introfirst-parameter to false, which means next time the visitor click on the link to current page s/he wont to have to se the intro again}
What I've done is at the beginning (my startscene) I declare/set attribute to all my booleans which controlls if the visitor have entered my 4 pages. And then I change their attribute when entering current page. E.g I enter music I see the intro and the parameter "musicfirst" is set false.
But that doesn't work.
To my question is it like in java that the parameters both can be global and local. Shall I print start.introfirst or what shall i print ????
I hope you understand what I mean.
Thanks for helping me /M8M8

How Would I Pass A Parameter...
How would I pass a parameter (or any method) into a scrolling text box?
The parameter would come from a .jsp file. It would function exactly like an <iframe>
It would work like this.... (I run a affiliate program)
I send out an email to my clients with new links.
The problem is some 1000 of my clients have Yahoo and Hotmail accounts, and both services will replace my links with theres. So I will create a flash text box that will be independent of those meddlesome kids.
When the email is delivered it calls the flash file which in turn fills the text boxes with dyn. data. And my clients cut and paste the untouched code into there pages.

I got a function like this:

So, as you already have guessed, the "choice" in the setence inside the function is the parameter that enters the function. The problem is this doesn't work..i guess i have to "say" that the choise in the _root.bla bla bla is the var that enters the function!
How to do that?

StartDrag With Or Without Parameter
I wish to drag a MovieClip keeping the position of the MC (movieClip) relative to where I first clicked on it, and constrain it into a defined rectangle.
My understanding is to use the following cmd:
myMovieClip.startDrag([LOCK, [0, 0, 200, 200]]) where LOCK = 0 -- "locked to the point where the user first clicked on the movie clip (false)"
But when I click on the movieClip, the MC reposition under the mouse at its registration point. Toggling my LOCK parameter from 0 to 1 actually does not make any difference.
The only way I can start dragging - without the MC repositioning - is by using the "startDrag" method with no parameter at all:
myMovieClip.startDrag();
The problem of course, is that I now don't have any limits to where the mc can be dragged.
Any suggestion would be greatly appriciated.
Thanks in advance.

Is This Possible? Action, Parameter
(Sorry bout the non-descript subject to this post)
Curious to know if this is possible:
function someFunc(var1, var2, act){
//do stuff here
--
//
if(stuff done){
act;
}
};
someFunc(100, 200, _root.gotoAndPlay(2));
The code above doesnt work (thats why i am here...), it simply runs the third parameter directly which i dont want it to, but i hope you're able to see what i'm trying to do. I want the third parameter to run when the code in the 'someFunc' is done.
I would greatly appreciate if anyone know of any solution to this problem and showed me how it done.
//edit:
I want to be able to run any sort of code in the, in this case, third parameter btw. In my real code i would for example have
this code: loadXML('xml/nyhetsbrev.xml', -4). Which is a call to another function to load an xml.
//edit
cheers

Default Parameter Value
It seems there is a neat new feature which allows you to set default parameter values when establishing a function:
function ball (xmove:Number = 5) {
ball.x += xmove;
}
ballMove = setInterval (ball, 50);
This will move the ball. However can the default value be a variable (something like this...although as is it doesn't work):
movement = 5
function ball (xmove = movement) {
ball.x += xmove;
}
ballMove = setInterval (ball, 50);
...or is there another way to change the parameter as the ball reaches certain x locations:
if (ball.x >= 100) {
//change the direction of the ball movement (-5)
}
