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?
I want to pass parameters when an event is triggered. My function:
private function keyChange(e:KeyboardEvent, setValue:Boolean):void
so that I can use the same function to set if a key is up or down. How would I write the event listener? I tried:
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyChange(,true)); however that didn't work.
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 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?
View 2 RepliesI have created different buttons on different movieclip. Then i assigned onPress event on each buttons. But the function of onPress event is not triggered. The arrangement of movieclips is following.
var mainMC:MovieClip = _root.createEmptyMovieClip("mainMC",0);
mainMC._alpha = 0;
var adImgMC:MovieClip = mainMC.createEmptyMovieClip("adImgMC",0);
var offerMC:MovieClip = mainMC.createEmptyMovieClip("offerMC",1);
var offerList:MovieClip = offerMC.createEmptyMovieClip("offerList",0);
[Code] .....
I have created an event as follows:
offerList.onRollOver = function(){
offerList.stopTween();
clearInterval(autoScrlTimer);
} offerList.onRollOut = function(){
duration = 0;
autoScrlTimer = setInterval(automaticScroll,duration);
ovrFlag = true
}
I doubt that the onPress event is not working because of the above piece of code.
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.
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.

Ok, I have 2 buttons on the stage. Each button does almost the same thing, so I want to create a single function, and each button calls that same function (we'll name that function "Navigate")... however, the function will need to end up doing something different dependant on which button was clicked.So, previously, in AS2, I would've added some code onto the buttons themselves with on(release) methods, like so:
Code:
// Define the Navigate function
function Navigate(myLabel){

Trying to migrate my way of thinking from AS2 to CS4/AS3. Ok, I have 2 buttons on the stage. Each button does almost the same thing, so I want to create a single function, and each button calls that same function (we'll name that function "Navigate")... however, the function will need to end up doing something different dependant on which button was clicked. So, previously, in AS2, I would've added some code onto the buttons themselves with on(release) methods (see CODE EXAMPLE 1) So, each button effectively calls the Navigate function, and passes a different frame label to the function. Now, I'm trying to recreate this functionality in AS3. As you all know, on(release) has been done away with (still don't know why), but we now have to use event handlers, so I'm trying to figure out a way to pass a different frame label argument to the Navigate function. Currently I can achieve that by using a switch statement to test which button was clicked, and act accordingly (see CODE EXAMPLE 2).

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?

I've got an XML file that is loading in data and is calling functions.
how to call the methods from classes with variables set from the XML file:
var functionToCall:String = xml.functions.func[0].to_fire.toString();

This calls the function perfectly.

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).
I am wanted to know how can i pass a parameter to the function which I'm calling using Delegate class. I know to pass params having static values such as true / false or a static string "hello".
Code:
var myFunc:Function = btn.onRelease = Delegate.create(tihs, releaseHandler);
myFunc.str = "hello";
function releaseHandler()

Here str can be retrieved as 'arguments.caller.str' inside the function.But in case i want to pass the reference of the 'btn' button. Then how can i do this ?
I have an FLVPlayback component with several ActionScript cue points designated along its timeline. I've written a listener that successfully executes a function whenever the video reaches one of my cue points. However, I'd like it to do different things depending on which of the cue points it has reached.
Here is my code:
Code:
// these are the cue points that I'm adding to my video
_root.thevid.addASCuePoint(33, "show1");
_root.thevid.addASCuePoint(43, "hide1");
[Code]....
Essentially, I would like for the function to accept a String name from the cue point, and then decide which action to take (either showing or hiding something). I don't know the correct syntax for accepting information from the cue point. Should I pass the cue point into the function as an object, then parse its name from within the function?
I have benn programming in AS2 for a while, but I'm moving to AS3, and I'm having some trouble with syntax and mostly with management of parameters and variables (actually I tried to work with functions in packages without good results T.T).

I have succeeded on disappearing the target (a coin in this case) when it is hit by the bullet, but the problem is that I can't quite find the way to dissapear the bullet properly.
