ActionScript 3.0 :: Passing Parameters In Functions And Event Listeners?
Jun 21, 2009I'd like to know what's the different using global functions and functions with param..Why using params? When the as3 developer uses it?

ActionScript 3.0 :: Dynamically Passing Parameters To Event Listeners
Sep 28, 2011I 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.
ActionScript 3.0 :: Passing Parameters To Event Functions?
Dec 16, 2008I like reusing functions repeatedly so I pass the object to the function (blur, drop shadow, etc.) but if an Event or MousEvent function is involved, I have to do things I don't like. In my example, I had to put the TimerEvent.TIMER_COMPLETE function as a sub function of the setTimer function. I would rather keep the functions apart but I don't know how to pass a parameter to the event function to tell it what movieclip(timerObject) to fade in. Is there a better way to do this?

Jun 30, 2011I have 2 functions. Each one is being called by a different event listener. Both event listeners work because I am able to trace strings in both of them.. my problem is that i am trying to create a variable that is local to both functions. The first function "working" adds a number to the variable and when the second event listener triggers function "notworking" which retrieves this same variable called "counting" both functions are called automatically by event listeners.. how do I do this? i am stomped!

ActionScript 3.0 :: Passing Additional Parameters To Function Listeners?
Apr 28, 2006hboxvar.addEventListener("mouseDown",dosomething(3 43));
hboxvar.addEventListener("mouseDown",dosomething(1 23));
hboxvar.addEventListener("mouseDown",dosomething(1 2342));
public function dosomething( somenumber:Number ):void {
//do something here
}
I try to do above function but I need to pass variable from hboxvar but not from inside function suggested by macromedia.
any one frustated with this way of passing multiple parameter which depends on what to pass in flex 2 using addEventListener ?

Passing additional parameters to function listeners You can pass additional parameters to function listeners depending on how you add the listeners. If you add a listener with the addEventListener() method, you cannot pass any additional parameters to the listener function, and that listener function can only declare a single argument, the Event object (or one of its subclasses).
ActionScript 3.0 :: Pass Parameters To Event Listeners?
Sep 3, 2009Suppose I want to create a bunch of buttons using a loop. But I want each button to do something different. Suppose the buttons are numbered and I simply want each button to print out its unique number when clicked. Heres what I have so far:
Code:
var t:CTextField;
for (var i:int = 1; i <= 100; i++) {
t = new TextField();

Ive tried many different things to get this to work, but none of them worked so I wont bother posting them all. At best, I got it so every single button traced "button 100 was clicked". I sort of understand why that happened, but I dont know how to make it work properly. Once again, all I could find was people saying "use custom events", but I think I need a lot more details than that. For example, I dont see how changing
Code:
t.addEventListener(MouseEvent.MOUSE_DOWN, buttonClicked);
to
Code:
t.addEventListener(MySpecialMouseEvent.MOUSE_DOWN, buttonClicked);

ActionScript 3.0 :: Add / Remove Event Listeners Within Functions
Apr 4, 2011What I am trying to do is, if a user presses keyboard (key 1), picture 1 should FadeIn and if a user presses keyboard (key 2) picture one should FadeOut and picture 2 FadeIn and vice-versa. With the code mentioned below it works fine sometimes if I am not pressing any other key while it is performing one action but sometimes it behaves weird also. What I want AS3 to do is not to take any action or in other words it should not listen to keyboard until it finishes the opening or closing animation of a picture or any other object assigned to the key.

ActionScript 3.0 :: Why Are Functions With Event Listeners Firing Themselves Again
Aug 23, 2009I've had this glitch for a long time, and I've tried several ways to get rid of it, and now that I just recoded everything to see if it was something I did, it's back again! basically, whenever I press space (regardless of whether or not I am listening for a space press [or any key press]), the last function fired by an event listener will run itself again, with the exact same arguments supplied to it in the first time.
For example, if I make a simple button to trace("text"); and take you to another frame. Once you get to that frame you can press Space and it'll trace "text" again! I really have no idea what's causing this, and it doesn't seem to be happening to me in new files. and there's too much code to show you, but I just want to know if anyone has heard of this before or if they have any theories to what's going on.

ActionScript 3.0 :: Remove Event Listeners In Separate Handler Functions?
Sep 17, 2010I've managed to create a button which on MOUSE_DOWN scales its parent object- it works just like windows in your OS, where you grab the corner and can change the scale of the window.
Here's how I've done it, (minus the MOUSE_DOWN listener)
Code:
function scaleDragHandler(event:Event):void {
var mcWidth:Number = event.target.parent.width;
var mcHeight:Number = event.target.parent.height;
[Code].....
However, it throws the error, "Access to undefined property 'scaleMC'" on the removeEventListener line. My thought was to put another listener for mouse up inside the first, but that sounds wrong
Actionscript 3 :: Flex Adding Event Listeners With Callback Functions Which Have No Arguments
Jun 10, 2009fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler);
private function uploadCompleteHandler(event:Event):void {}
Above is one way to add an event listener in Actionscript. By default the callback function needs to have an argument with name event and type Event. Is there a way to declare this function without any arguments :
private function uploadCompleteHandler():void {}
Edit : It's possible to add an event handler without any arguments in mxml. So one student wanted to know, why isn't it possible to do the same in actionscript?
ActionScript 2.0 :: Passing Parameters With A Mouse Event On A Button

ActionScript 3.0 :: Multiple Functions/Listeners Similar Process?
Jan 13, 2012I am adding a different listener to each button in the menu and there are several menus as well, then each one of those functions adds a different child depending on the button and also pushes several values to the Array list, in this example called objectsOnStage. I will be running this structure function 40 times with each of the highlighted elements changing accordingly.
//Listener and function for Button01
menu01.button01( MouseEvent.MOUSE_DOWN, button01Function);
function button01Function(event:MouseEvent):void

Professional :: Passing 2 Parameters To A Swf?
Nov 9, 2010I need to dynamically pass 2 parameter to an swf movie to make it work properly, they are a number and a boolean. To do this I've changed the html page which contains the movie to php, I pass to the page the parameters' values through GET. The values are correctly passed to the page, I've tried to print them.
I build the call to the swf in this way collpreloader.swf?connid=<?php echo $_GET['connid'] ?>&animazione=<?php echo $_GET['animazione'] ?>
collpreloader.swf correctly reads the connid parameter, but animazione results always true.

IDE :: Passing Parameters With AddEventListener?
Mar 3, 2009So I have an MC that has 6 labels and 6 buttons all with different names. When you click on a button, it needs to direct you to it's appropriate frame label in the MC. Now, since AS 3.0 has done away with inline functions, how the heck do I code it so I don't have a function with a bunch of if statements inside of it in addition to all of my eventListeners that I have to add to each of my buttons? In AS 2.0, I would have done it like so:
Code:
function movePlayhead(whichOne:String):Void{
this.gotoAndStop(whichOne);
} button1_mc.onRelease = function():Void{
movePlayhead("label1");
};
button2_mc.onRelease = function():Void{
movePlayhead("label2");
};
Etc...
With AS 3.0, you have to add eventListeners to each of your buttons where each eventListener calls a function, but how can I write it so I don't have to write a bunch of if statements inside the function the eventListeners are calling in order to test for which button is being clicked? Like so:
Code:
button1_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
button2_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
button3_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
function movePlayHead(event:MouseEvent):void {
