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:
ActionScript Code:
// stylesheet for lines
var params1 = {
thicknes: 1,

I have a function gameTimerInterval() set to run every half second. Every x of those intervals (the value of x varies in this situation), it creates another interval that calls the function birdTimerInterval() every y of these new intervals. Basically, gameTimerInterval() determines when a new flock of birds will enter, and then birdTimerInterval() controls how each individual bird in the flock comes in (one at a time). The thing is, there can be multiple flocks coming on the stage at the same time, so birdTimerInterval() will need to receive a parameter so it knows which group of birds to control. The only way I could see achieving this is doing something like dynamically passing the name of the interval that's calling the function, as I don't know how I could use global variables or arrays to distinguish which flock should be moving.
View 4 Repliesis it possible to store a list of params needed for a function in an array and then use that in a funciton call?
[Code]...
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.
I have a 16x16 grid of buttons, and want to add an event listener to each of them so when clicked it will return its unique grid position number (anything between 0-255);
What I have so far:
public static const GRID_SIZE:Number = 16;
private var i:int;
private var j:int;
// Constructor
public function Grid()
[Code] .....
Unfortunately every time the listener function is called by each button, it uses the last two values of i and j, which in this case return 255 for every button.
I just am looking over the CS4/3D methods and am a little bit stumped at this: globalToLocal3D... I am just trying to determine parameters to dynamically resize the width of myMc (once it is pushed back in z dimension - say to 2000) - I am basically using the globalToLocal3D method - yet the compiler is throwing errors - Error #2004: One of the parameters is invalid. here is the code that should be self explanatory (other than the fact that I am doing something wrong)...

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:"A", KBP1:1, KBP2:0, KBP3:0, KBP4:0 },
{Impact:"B", KBP1:0, KBP2:0, KBP3:0, KBP4:0 },

How do I make some parameters of a function optional?

I 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();

Something like[code]...
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...)

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:

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:

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?

View 5 RepliesI am trying to to attach a function with parameters to the timer but it says "unrelated type function" is there any way to get around this??
code example:

redoTimer.start();
this wont seem to work but is there a way to pass on arguments???
I'm attempting to write a performance testing function that can take any function, run it X times and spit out how long it took that function to run in AS3. I've got it working just fine if a function doesn't take any parameters but it comes up with an error otherwise.Here's the 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"});
}
[code]....
I am assuming that I must pass some sort of parameter over to the other function that is calling the resizeGabHandler()
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.

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:
[AS]

Here I've got this bit of code that works alright, but I would prefer to have the parameters that are being sent through myTween.tweenMe(_text, 40, 300, 150, 100, 4000) originate instead with the call to tweenerIt. The problem seems to be that the tweenerIt function needs to receive the e:Event parameter, which is some sort of 'behind the scenes' type of thing that I don't fully understand. If I try putting ... _text.addEventListener(MouseEvent.MOUSE_DOWN, tweenerIt(_text, 40, 300, 150, 100, 4000) and then something like.. private function tweenerIt(param1, param2, param3, etc..., e:Event):void, it doesn't work.
Code:
_text.addEventListener(MouseEvent.MOUSE_DOWN, tweenerIt);
}
private function tweenerIt(e:Event):void {

I'm building an app with transitions out of each page. I'm using the code below to store references to a function and parameters for that function to use. Is this the best approach though?
[Code]...
So, basically, the photo_btn is writing the references and variables, telling the transition to play, when it reaches the end, it calls the function that's stored in the __func ref and uses the parameters. I'm doing it this way because I have a bunch of nav buttons that all call different functions, and this is the only way I could figure out to get transitions to play and then call the desired function at the end.
When assigning a function to onEnterFrame, for ex. onEnterFrame = someFunction, you do not include the brackets or the script will not run properly. my question is then, how can you assign a function to onEnterFrame while specifying parameters for that function? I tried onEnterFrame = someFunction(param1), but the function will only execute once.

How can I set default values for the parameters of a function in AS2? I am trying the common way but it doesn't work...

I am creating some sort of interactive background and at is current state of development the master constructor function have like 15 parameters that need to be put in. I can add at least 6-8 more and make it really flexible, but I start to wander if this will be such a good idea. I am not sure that the general people that I am developing this class would like to type so many parameters before using it to full potential. So there is only 2 must enter parameters and like 13 that you may want to change or leave the original values. My question is if there is some common practice about this? Is it to many or no? Just for idea this is the function at this point (working ok):
Code:
new Maker(textTest,15,150,200,2,8,3,5,0.3,1.5,4,360,0.003,30);
Look at the simple code below:
Code:
stage.addEventListener(MouseEvent.CLICK,traceMe);
function traceMe(evt:MouseEvent)
{
trace ("hello world!");
}
What if I want to pass a parameter to the traceMe function? There is a way to do that?
