is it possible to determining what object calls a function based on an event listener? for example, i have 2 buttons on stage that call the same function when they are clicked. i'd like the function to determine which button was the sender.
[Code]...
Alright, I've looked online at a bunch of different collision tutorials but they don't explain what I'm looking for. I want object A to hit object B and then execute a function via to a Event listener.
View 1 RepliesI'd like to simply scale down a movieclip (that I'm treating as a button) when the user presses their mouse button. When users release the mouse button, I want my button to scale back to it's normal (.scaleX = .scaleY = 1) size. My button also has listereners for a ROLL_OUT event to turn off (.alpha = 0) a highlight movieclip that rests atop movieclips showing the different states the button can be in.
When I roll over the button, the higlight comes, but there is an annoying flicker problem. For some odd reason, when I press the mouse button the ROLL_OUT event handler function is called, yet I didn't scale the movie down enough for the cursor to be off of the actual button itself. I do not want that flicker. I'm not sure why ROLL_OUT is being called even though the event is clearly a mouse down, and within the mouse down event handler I am scaling the button movie clip, but not enough to remove out from under the cursor. In other words, if I click the button at its registration point, a flicker appears.
Here's my code.
//this add all the appropriate listeners to the button private function addMouseListeners() { this.addEventListener(MouseEvent.MOUSE_OVER, mouseOver); this.addEventListener(MouseEvent.MOUSE_DOWN, mouseDown); this.addEventListener(MouseEvent.ROLL_OUT, rollOut); this.addEventListener(MouseEvent.MOUSE_UP, mouseUp); }
[code]....
why my rollOut function is being called when the mouse button is pressed, and called once more when the mouse button is released.
When you click on the button something happens. However it seems redundant to me that in the declaration of myListenerFunction, the event object e of class MouseEvent, actually has to have its data type MouseEvent mentioned.

Is there a method to see which event called a function and do something different based on that specific event?[code]...
View 3 RepliesI can't think of a way to write a function that returns an object that is loaded from an external swf. I need to be able to make a function that waits for an event listener before returning the value. I want to be able to create objects that can load in external swfs with minimal and no redundant code.
Here is the over all logic of my function:
Code:
//First create an object and set it to function that loads in an external file
var MaskFrames:Object = loadFile(parentObjectName, "swfs/", "file.swf");
//Create the function that returns the loaded swf as an object

I've loaded text from database and I make links for each title, works good, until I try to add a item counter to have a next and previous button, allowing user to load 12 records.when inserting the next code, my links fire n times, not just once as expected, making browser to unespectly quit.what can be the reason?
some explanation
init is the number I need to increase or decrease to make database query
total is the number of received records by query
total_geral is the number of all records in database, so I can know if I must or not have a next button
t is the name of the mysql table where query should happen
code:
Contadores
function contagem(init:Number, total:Number, total_geral:Number, t:String):void {
var contador;[code]...
I'm moving on to my next massive programming project and I'm trying to decide whether I should code it in as 2.0 or 3.0. I came across the new click event model in 3.0. Right now it's looking like a pain in the butt to me. So now I have to make a function and add it as an event listener? what the hell? What's the benefit? I understand stuff like this makes AS a more complete language but it's kinda annoying.
View 1 RepliesI think I had this issue before I decided to try and learn mvc, which I'm doing right now. it's not a complex problem. But I can't figure it out. First, should I add swf address to my controller? that's what I think, considering it's between the view and the update. But mainly... I feel like it's just going to loop.. for instance. I add the .setValue method on a click handler. and it changes the url and everything.. grand. but during the change it fires off the change event of course.. now how can I make adjustments to my file based on the change event listener, if it's going to fire every time something in my movie sets the value?? as you can see i'm trying to use simplemvc's classes.. i'm just trying to learn though.

how do i use two event listeners on one function. For example, i want a mouse_move and enter_frame event listener with one function

what appens when I add an Event Listener to Object Event?
Following the logic with the display list in AS3, I thought only Classes who inherit flash.display.InteractiveObject could react from events coming from mouses (or keyboard).
I'm trying and it doesn't seem to like it. I'm guessing it's not possible?[code]...
View 5 RepliesI am working on a game for my university project and I have run into a bit of trouble. I have the following code here:
function launchBall() {
this.stage.addEventListener(KeyboardEvent.KEY_DOWN ,launchBallHandler);
function launchBallHandler(e:KeyboardEvent):void {
if (e.keyCode==32) {
[Code].....
Its set up so that when a ball goes off screen, it resets to a coordinate and launchBall is called.
LaunchBall then adds the event listener to see when the Space key is pressed and that starts the ball moving again. The problem I have now is I cant seem to get rid of that eventListener. I have tried removeEventListener and that doesn't seem to work. I have tried:
if (ball.xVel>0 && ball.yVel>0) {
removeEventListener(KeyboardEvent.KEY_DOWN,launchB allHandler);
just below that code and that doesn't work either. It's not spitting any errors out at me but I am completely stumped.
I just started a course that does a little flash. To teach us they have us build a brick breaker game. I have come to a part were I have to remove all the Listener that were created for the game. Each level is a movie clip and when the level is over the level instance is removed from the child. From what I understand when the level is removed the Event.REMOVED_FROM_STAGE becomes true and the function attached should be called however it is not. Here is the code of the function that sets the listener and the function to be called:
[Code]...
private function myFunction(numIn:Number){
trace ("numIn " + numIn);
}[code].....
This won't work, but can you see what I'm trying to do? It's kind of like a function pointer, or when you pass a function name into an event listener.
I have a method which registers an event listener to each of the MovieClips in an array I have. The method is inside a class, and so is the listener function. The problem is, I'm getting an error that's says "Access of undefined property handleNavToggle", even though is declared.
[Code]...
So I guess the usual stuff is to have
function listenToEvent(evt: Event){
//stuff
}

How do i pass a variable to a function from an event listener which is inside a function Below is a function that is called when after loading some variables
function dataOK(mydataevent:Event):void{
var j:int = 0;
do {
trace(j);
[Code]....
This is a simplified version of the original code. The above function generates an error because j is undefined in the function. I am wanting to get the variable j when the button is pressed.
How do I pass the variable j to the Button_Click function?
I'd like a movie clip called "following_cursor_mc" to follow the cursor, regardless of which of several different frames the playhead may be on. I've reproduced the code below on each frame in which I would like the cursor to be followed by "following_cursor_mc" but these errors are thrown for each of the frames:

Just wondering how to set up an event listener to trigger a function when a movieclip reaches a certain y position?
Say the movieclip is called ball_mc.

How would you remove an event listener from a nameless function?[code]
View 7 RepliesI have a set of buttons on, and what i would like to do is change the value of a variable, depending which button you are over.i know i could do this by writing an event listener and a function for each button, but this is too time consuming.I'm sure in the old days it would have been as simple as if btnwhatever.mousedown = true then.... but now i have no idea.

View 1 RepliesSo I have an event listener, and I call a function from it.. but I want to pass some variables along with it as well.Is that possible?
View 10 RepliesI am trying to create an event listener to check that a function has completed before the next action is run. In simple terms I have a module that is opened and closed via two functions... module_open() and module_close().Each function has tween elements that must complete before the next element is processed... i.e the next function, etc.This is the code I have ( have attempted to create an event listener but I seem doing something wrong. I am not even sure that it is possible to create an event listener that checks for a function finishing before calling the next function.
Code:
function onAbout(event:Event):void {
module_close()
module_close.addEventListener(Event.COMPLETE, onClose_Complete);

Say I have the following function
Code:
function myVideoFunction(event:VideoEvent):void {
do some stuff....
}
but i want to call it from the event listener
Code: button.addEventListener(MouseEvent.CLICK,myVideoFunction);
I cant because it runs off a VideoEvent, not a MouseEvent.The obvious work around is to copy and paste the function and rename this part, or alternativly just make a function such as:
Code:
button.addEventListener(MouseEvent.CLICK,callMyVideoFunction);
function callMyVideoFunction (event:MouseEvent) {
myVideoFunction(null);[code].....
I have a movie clip being dynamically added to the stage via an AS3 linkage call:
gameOver_mc = new GameOver();
stage.addChild(gameOver_mc);
The movie loads as required.But when the movie has been added I want the user to be able to press spacebar and a function to run.So in the GameOver.as class I wrote the following:
Code:
package
{
import flash.ui.Keyboard;
[code]...
But as soon as the movie clip tries to load I get the error message: TypeError: Error #1009: Cannot access a property or method of a null object reference.I would have thought this would work fine. When I trace the statement in the Constructor function is works. Its only when I try to add an event listener that I get the problems. So am I not allowed to add event listeners from a dynamically loaded class?
I'm trying to add an event listener inside an object but it doesn't seem to work. other OO languages it makes sense for an object to be able to attach events etc itself rather than have some external action do it.Here's an example of what I'm trying to do:
ActionScript Code:
package {
import flash.display.MovieClip;
public class Player extends MovieClip {
[CODE]....
This gives an error "1120: Access of undefined property MouseEvent." suggesting that I don't have access to MouseEvent from within the instansiated object.What I can do is create an instance of the class from the Document Class for example and then do the following:
ActionScript Code:
newInstance.addEventListener(MouseEvent.CLICK, newInstance.mouseClick);
run event listener through dynamic object call
