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 RepliesHow 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'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:
package
{
import flash.media.Video;

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?
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 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?
View 2 Replieslets 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'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:
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;

How do I make the color array, dColors, an optional parameter?[code]It gives me a "1047: Parameter initializer unknown or is not a compile-time constant."I've tried a bunch of different ways, but all I get are compile errors.Don't forget to drop a colorpicker control in to your library if you copy out the code.
View 2 Repliesis it possible to store a list of params needed for a function in an array and then use that in a funciton call?

or something like that?? Prob have to iterate the array but how do i get the params into the function call? Is this even possible?
I'm having some trouble passing parameters with a function that is itself being passed as a parameter.In my application code I'm instancing that class five times:they are buttons in a menu.In that class, I've got an onRelease handler that does a number of things when a button is released, one of which is to invoke a function that is defined in the application level of the code.My problem is that I don't know how to send the function parameters.In my StandardButton class I have:
class StandardButton extends MovieClip
{
/* define properties */[code]..........
The function is successfully being "sent" to the StandardButton class, but without any parameters.How can I send parameters to the class instance with the way I've got this architected.
How would I write a procedure that would build this array such that I could choose as many parameter names such as KBP? I wanted?
public var expenses:ArrayCollection = new ArrayCollection([

{Impact:"B", KBP1:0, KBP2:0, KBP3:0, KBP4:0 },

I want to create an static drawing (say any animals like giraffe) using some points, lines, drawing etc. Now i want to update the drawing by passing the parameters say height of his legs, its width or its color.The parameters are supplied from the web page. The image will be a 2D image.I am searching on which technology should i implement this for more than 10 hours but cannot find any perfect solution.Right now i am thinking i can use Adobe flash in which i can do some programming to create an drawing and change the drawing by passing the parameters to a Flash file, i think we can pass it when we embed an flv.
View 2 RepliesI have some functions that have mouseEvents for their param and I am wondering how those can be use without the param. Meaning those functions where set up to work with buttons, but how can call those when I don't have a button to call them? Here is an example of one of the functions:
function forward(e:MouseEvent):void
{
ns.togglePause();

Since I have to loop through all of them. I can convert them to an array inside the function, but it would save me 10 lines if I could just enter them as an array in the function parameter (as I have 10 variables 1-10...)
So say I have a function that has some number of optional parameters but I don't like to write the function more than once. Instead just use for loop or such to iterate the parameters through and give them to that function.
Here's a raw scetch:

i am loading an image with a loader, and in onComplete function i would like to call calculateRatio function and pass it Loader.content.width and Loader.content.height so it can compare it with the current stage width and height and resize image proporcionally to fit the screen. how would i go about passing that parameters?

I have a hard time getting this
Code:

function loadFirstTime(whichXML:String):void {
XMLLoader = new URLLoader();
XMLLoader.load(new URLRequest(whichXML + ".xml"));
}
I'm having a problem with a menu that is loaded from a xml file. I want to control the onRelease action for every button in the menu from one XML file, but I can't seem to get it to work... The buttons in the menu each have to call a different function with parameters which are declared in the flash file. The trace output shows the right function call, but it just won't fire the function.
This is an example of one of the nodes from my XML file with the function as node attribute:
PHP Code:
<locatie menu="LOCATIE )" label="LOCATIE" functie="showTextpage(myObj.locatie, CurrentProject)"> <image></image> <text></text> </locatie>
And this is my AS which loads the XML and sets up the menu:
PHP Code:

{Flash MX 2004 Pro}

The above does not work. Infact the function is not even called. How can I pass parameters to such functions. I dont wanna do the following:

I have 40 buttons on the stage. Their names are contained in the Array musicGrid. What I'm trying to do with this code is attach an EventListener to each button so that it will call the function mgMouseBehavior with a parameter to identify the button. For example, I want the button at musicGrid[0] to call the function mgMouseBehavior(0). I want the button at musicGrid[32] to call the function mgMouseBehavior(32), and so on.
However, if you try to add parameters to mgMouseBehavior in the addEventListener, for example:
Code:
musicGrid[i].addEventListener(MouseEvent.CLICK, mgMouseBehavior(i));
Then you get Error 2007: Parameter listener must be non-null. How would I accomplish what I'm trying to do?

I'm trying and it doesn't seem to like it. I'm guessing it's not possible?[code]...

I created a function to handle the size of a talk bubble for a chat application based on what's being loaded into the movie clip I want it to scale it's height that is. I have it working when like this
Code: Select allif (!gabChatBox.gabOp1.text == "") {
Tweener.addTween (gabChatBox.talkBubble,{height:200, time:1, transition:"easeOutElastic"});

I am assuming that I must pass some sort of parameter over to the other function that is calling the resizeGabHandler()
