ActionScript 3.0 :: Dynamically Passing Parameters To Event Listeners
Sep 28, 2011
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.

hboxvar.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).

Suppose 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();
[code]...
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);

I am fairly new to AS3.

vancouverMC.dotsBttn.addEventListener(MouseEvent.M OUSE_OUT, mcOut(vancouverMC));
function mcIn(mcName:MovieClip):void{
mcName.gotoAndPlay("in");
mcName.ringMC.gotoAndPlay("on");
} function mcOut(mcName:MovieClip):void{
mcName.gotoAndPlay("out");
mcName.ringMC.gotoAndPlay("off");
}
Why this is Not Working?

I'm stuck with an issue and I cannot understand why it behaves like that. In a for loop, I'm passing the for index as an event parameter. However, the eventHandler is getting the wrong index, but the right target...

I 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!

I 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?

I would like to pass Parameters to a functions from a button click. Currently I need to call a function that in turn passes the Parameters.
example
gardengate_btn.addEventListener(MouseEvent.CLICK, onClick_gardengate);
function onClick_gardengate(e:MouseEvent):void{
/*Sends the xml and the paintingCount_Numb to the parseXML function.
This will display the text and images for each painting
*/
ParseXML(xmlData,0);
}
I would think that i could just do this but it gives me an error. gardengate_btn.addEventListener(MouseEvent.CLICK, ParseXML(xmlData,0)); 1067: Implicit coercion of a value of type void to an unrelated type Function.

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?

I'm trying to dynamically load different MovieClips based on user input. Several of those clips have embedded url link symbols. How can I add event listeners to the url links if the dynamically loaded MovieClip does not have an instance name? Seems like I can (right?) apply an instance name when the clip is loading, but the event listener doesn't compile because the name is not there yet, so that seems out.

I have a parent SWF (Parent) that handles user navigation between multiple children SWFs (Child_1, Child_2, Child_3). How do I add event listeners to the navigation buttons on the children SWFs so that the user can move laterally between Child_1, Child_2 and Child_3? I can think of two options but can't get either one to work:
1) The parent SWF sets up the event listeners when it loads a child. So, I use a loader on Parent to load Child_1 and in Parent add eventlisteners to Child_1.myNavigationform.myButton.
The problem here is that the Parent is only handing the loader instance and I can't think of how it would drill down to the individual objects within Child_1.
2) Child_1 adds the event listeners to its own objects. This just reverses the problem. Child_1 has no problem accessing its own buttons but when a user clicks them it has no way of accessing methods on parent so that Child_2 can be loaded.

I've created a drop down list and populated it with dynamic buttons. (I made a DropDown_btn class with a dynamic text field in it and then filled the button text from an xml file). On rollover I tint the button blue and then set the tint back to black on rollout. When you click on the button I'd like it to stay blue until a different button is clicked.
I thought on CLICK I'd run a function like this:
ActionScript Code:
function removeRollover(evt:MouseEvent):void {
evt.target.transform.colorTransform=c;
evt.target.removeEventListener(MouseEvent.ROLL_OUT, btnOut);
evt.target.removeEventListener(MouseEvent.ROLL_OVER, btnOver);
}
...and then I need to addEventListeners back to any button that doesn't have them and set that button back to black. I could do this by looping through an array of the buttons but I can't figure out how to access them as objects.
I also gave them each a property of "buttonValue" when I loaded them so I can access event.currentTarget.buttonValue (which in this case is a number from 1-5) but once again I can't figure out how I might leverage this information.

I have already created a custom mouse event which seems to work fine. It is simply a mouse event which passes an additional sound object. The problem is I am passing this event to another class which checks for collision of a movie clip with another and if true it adds the sound to an array. What I think is happening is a type conversion problem between my customEvent and the MouseEvent. [code]...

Can event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:
ActionScript Code:
pseudo code:
class main {
main() {
[code]....
This doesn't work. Why can't the main class listen for an event on the thumb class?

I 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.

So 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 {

An odd thing is happening for me, my eventlisteners only fire off once then they seem to stop working.
This thing is a movieclip that slides up the parent movieclip and another movieclip within mc slides it down. They only work once.

slider.up.addEventListener(MouseEvent.MOUSE_UP, activateSlider);
slider.down.addEventListener(MouseEvent.MOUSE_DOWN, activateSlider2);
var frameBoolean:Boolean = false;

What I want to do is to pass parameters from the browser to flash. I searched and seems like the best way is FlashVars. However, I have tried different codes and can't get Flash to detect the parameters. I decided to follow the example here and just copy and paste the whole thing (just changing the "main.swf" to my swf name): [URL]. The flash loads, but it only shows "param:" without anything else. I gathered that it probably is a more fundamental problem. (e.g. the way I am debugging, or some settings, etc.) I am using CS4 trial version AS3.

I want to open a .swf file with a parameter for instance test.swf?beer=good and set "good" (the "good" parameter is going to constantly change) as a variable in the script so that I can add it to the stage in the swf file. The problem is I can't seem to figure out how to read the parameter so that it can be placed in the script.
For instance I have it set to:
var beer = "";
on (release) {
getURL("http://www.google.com/search?&q="+ beer , "_self");
}
