ActionScript 2.0 :: Function Won't Recognize A Variable Parameter?
Oct 22, 2009
For the record I am running Flash CS4, but am using actionscript 2.0 (its just what I know, and I don't feel like learning 3.0)-So I'm making a contact list, and each of the names will be clickable to bring up more information. There's going to be a lot of names, so I'm trying to keep the actionscript concise. The code is shown below in a simplified form, but essentially I have created a variable for the hexadecimal color, and I have created a function which will change the text color of each of the name buttons. This works, I have tested it. But, I don't want to have to tell the function to run for every single name button
(eg. changeColor (option1 , testColor);
changeColor (option2 , testColor);
changeColor (option3 , testColor);
etc..)

My goal is to change the time for setInterval each time the function is called. Planning to replace myInterval = 5000; with a randomized number. My problem is getting setInterval to recognize the myInterval variable from the function.
var myInterval = 1000;
callback = function() {
_root.myMovie.gotoAndPlay(1);[code]....

SO - I tried to create a for loop that would run the changeColor function for each button without typing it a million times. The one below should run from "option1" to "option5" for instance. I originally tried entering the equation "option" + i as a parameter, but it did not work. So I tried the code below where the for loop creates a variable which is assigned the value option1, option2, etc. as it runs through the loop. I added the trace code, and it is showing me that MCname is holding the correct value. However, the changeColor function still refuses to insert the MCname variable as a parameter. The testColor parameter is a variable, and that will work, so why not the MCname one? I also tried replacing the MCname variable with the name of a button (option1) and it runs fine. I just don't want to type in every single option name for the entire list.Sorry for rambling, but I'm trying to fully explain the situation.. If the code is all correct, why won't the changeColor function accept a variable for the first parameter? Is there a way I can get this to work without having to copy and paste the changeColor(option, Color) code for every button (there could be over 100 options)
CODE:
var testColor:Number = 0x33ff00;
function changeColor(buttonName , myColor:Number){

I need a way to wait running the parseCSV command until the readFile event has updated the content of importData. I have seen a few things about custom event dispatchers but cannot quite figure out how to use them in my situation.
private var importData : String;
public function importFile(event:MouseEvent):void {
var data:String = chooseFile();

I have a function with three parameters, that works fine when I type in the parameter values. The function is tweens(MCname, targX, targY) and it runs properly when I use tweens(btn1, 150, 200) for instance. I need the function to move 6 different movie clips, one at a time, and I am using a variable (Counter) and an if statement to tell the function to run again after one of my tween classes finishes. The code all works, and it will run six times with the same clip if I just type in one of the movie clip's instance names as the MCname parameter. BUT, if I try to use a variable (BTNname) to serve as the MCname parameter, it will not work, making it so I cannot apply the function to my 6 different movie clips. I put a trace on the MCname parameter, and it returns the correct value (btn1, btn2, btn3, etc) but it is not moving the corresponding movieclips. I've tried a number of different methods, but nothing will work..[code]

ok so i've been stuck on this for a while...What i'm trying to do is create a function that updates a global variable (randomVar) that is itself a parameter in the function e.g
[Code]....
Basically, i thought randomVar and vari were the same so when vari was changed randomVar would too but that's not the case. So how do i make the parameter equal the new value(5). I want to repeat the function using different variables so putting randomVar = vari in the function is not possible.

Forgive me for this stupid noob question but I want to call a function (loadList) that originally gets triggered after a mouseevent from another function (addToXML) that does not have an event.
The loadList function takes info from a XML var, sticks it into an array which then gets loaded into a tile list and that is working fine.
The addToXML function when called adds elements to the XML var after which I want to call the first function with the event parameter so it refreshes the items in the tile list.
I know it can do this by creating a new array and loading that into the tile list in the addToXML function, but it be much simpler to just recall the function.
I have tried things like
Code:
addToXML.addEventListener(Event.COMPLETE, loadList);
but all the event constants I have tried give me error messges like "1061: Call to a possibly undefined method addEventListener through a reference with static type Function."

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 recently took over an AS3 project someone else programmed. It's quite well done and nicely object oriented. However, I have come across something I have not seen before.
protected function addedToStage ($event:Event) : void {}
The parameter in the function above uses the prefix $ before the parameter name "event". What does this do - if anything?

I'm working on a sliding gallery like Hulu. Setting it up and the sliding slides in and out is working fine. However, I need to add and then remove a button to each slide as it comes in and goes out. (I initially tried including the button on each slide, a mc, but this proved problematic for the event listeners). So when the file loads up, I add a mc to the first slide of the group like so (features[] is an array of movie clips - my slides):
Code:
var goBtn:MovieClip = new FeatureButton();
features[0].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
So I add the button/mc to the first slide - works just fine.
So there are two handlers, next and previous. So I started with the next handler. The first thing I have to do is kill the button on the panel that is sliding out, so I do that like so:
Code:
features[featureCount].removeChild(goBtn);
goBtn = null;
(featureCount is a counter keeping track of the slides). This works fine. I click the next button, and the button on the slide disappears and we move to the next slide - perfect.
So then I add the following next - exactly like I did in the beginning:
Code:
var goBtn:MovieClip = new FeatureButton();
features[featureCount].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
This time adding it to the current slide coming in - but this generates the following error:
Code:
TypeError: Error #2007: Parameter child must be non-null.
at flash.display::DisplayObjectContainer/removeChild()
at featuregallery_fla::MainTimeline/nextFeature()
How I'm getting an error on the removeChild() when that is already gone. I assume "parameter child" means goBtn - yes it is null because it's been removed. But I'm not trying to do something with that. I can only guess this is a variable scoping issue with goBtn - but I'm not seeing how to resolve it. Flash file attached.

I want to create a component with a variable/parameter that is a method it calls when (clicked on for example). In "Flash UI Components.fla" the they do this and I studied the code but cant get it to work. The Push Button one has a click handler, but the way it is actually called in the script is like this:
this.handlerObj[this.clickHandler](this);
That bracket/parenthesis thing is not working.

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'm trying to program a race timer with OOP, and I've been adding more and morefunctionality to its class. Everything had been running well, until I had the idea to put a countdown() function, to make a cool countdown effect. Things got worse when I wanted to make the countdown function to call another function when the countdown effect has finished.The code runs well when I first pass a function parameter from the Main class to the Timer'scountdown() function. The problem begins when I want that function to be past again on other private function of the same class, because this time, the function becomes nullOn the Main class constructor, I 've written the following line:

I am sending a name of a function via parameters to another function. This allows more usage of a single function. However, the button commands work every-so-often. The message appears everytime with no problem.
Code:
_root.msgReveal("This is just a random message. Click the ok button to close.", false, true, false, false, _level0.msgHide(), false);
Code:
function msgReveal(msgString:String, btn1B:Boolean, btn2B:Boolean, btn3B:Boolean, command1:Function, command2:Function, command3:Function) {
msg.messageBox._visible = true;
msg.messageBox.textF.htmlText = msgString;
msg.messageBox.btn1._visible = false;
