ActionScript 3.0 :: Fake An Event For A Function Parameter?
Jul 3, 2010
The following code is how you call a function with an event listener. There is a disadvantage to this however: you can -only- call loginCheck with a MouseEvent. If I want to call the function through code, I can't just write loginCheck(); and have it work.
[Code]...
But I have always wondered if there was a way to run a function with a MouseEvent parameter through code. Is there any way to fake a MouseEvent and send it as a parameter to the function?

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 want a generic function that lets me align a child object to the bottom edge of a parent object. The problem is that the parent object can either be a simple movie clip or the Stage. With Stage, I would have to use the stageHeight property rather than the normal height propery.

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 function that receives a function as a parameter. example:
function foo(bar:Function):void() {};
how can i set a default value for the function to be an empty function so the user will not have to paste a function as a parameter ?

I am dispatching an event and I would like to add a parameter to the event. Is that possible? The event I have is dispatched like this: dispatchEvent(new Event(CuePoints.TIME_IN, true));and gets listened to like this:
cues.addEventListener(CuePoints.TIME_IN, addDefLink); How can I add a parameter to this? Or would this be done differently? All I want is a uint that gets sent with it each time the event gets dispatched.

I'm new to ActionScript and have a fairly basic question. I want an eventlistener to call a function and pass it a parameter that will send the movie to a specific frame. My code generates and invalid parameter type error. It's as follows:
TL_AboutUs_btn.addEventListener(MouseEvent.MOUSE_OVER, DropSubMenu(10)); // calls a function to drop a sub menu
function DropSubMenu(sm:number)
{ gotoAndPlay(sm);}
Error is "1046: Type was not found or was not a compile-time constant: number."

I'm using an HTTP request to download a image in binary format. When the downloading is complete, I want to process it, but I also want to pass the image's ID to the complete handler function.

What is the difference between :
giving a function reference in the result attribute of the HTTPService class like this :
protected function httpserviceCheckUpdate_resultHandler(event:ResultEvent):void
{
var version:Number = event.result.text.version as Number;[code]....
If both of them are same then how can I provide the event parameter using the second approach (as written in the result attribute of the httpservice class)? Which one of them is the better way of doing things in FLEX.

For example:
for(var i:int=0; i<someArray.length; i++)
{
var loader:Loader=new Loader();
loader.load(new URLRequest("http://testurl.com/test.jpg"));
[Code]....
The second paramter (i) for imageLoaded is always 1, I guess because i no longer exists and is defaulting to 1. Is it possible to get that second paramter to be evaluated when the load is started rather than on complete?

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?

Essentially, 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]...

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:
ActionScript Code:
timer.countdown(5, false, myFunc);

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;

Simply said, I want to have an inputtextfield, a button that is linked to the textfield and a dynamic textfield as an display, to display stuff, which comes from the inputtextfield and the button.Then, I want to have items in the actionscript, like item1 = 5, or item1 = 1a, or 1a = item1. Just some code that equals to another code. But for now item1 = 5.For the button that is linked to the input textfield, has to calculate something when pressed and the dynamic textfield will display it. So if I would type in the inputtextfield 5 and press the button, it will be as example multiplied by 2, so the dynamic textfield will show 10.
Still following? The point is, I know how to set something like that up, but what I want is that when I type item1 in the textfield (which equals to 5) and press the button the dynamic text will show 10, because "2 x instance name inputtextfield" (in which intem 1 is typed, which equals 5) should be 10 right? But when I try to do this, the dynamic text will show nothing or some error. but when I type directly in the code "2 x item1" and press the button it will show 10. But I want it to double link, so "2 x (instancename inputtextfield which equals to what is typed in the field, this case: item 1 which equals to 5) and not that it stops to item1, so it will freak.

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..)
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){
