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 it ever preferred to not declare the data type of the return value of a function? Data type of return value is not declared:

I know a removeEventListener will removes them both, so I am guessing that in reality I have only one listener taking up system resources?
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 Repliesis 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.

I know I can create a custom event and associate data with it and retrieve it in respective Event Listener. But What I am interested to know is, is there a short method (without having to extend Alert Event Class) to associate parameters to its alert Listener.
View 2 RepliesI have a mc (squareContainer) that can be dragged around. It also contains other mc's that uses hittest and changes colour on mouseDown.I want to add another squareContainer (eg squareContainer2) that contains the same mc's with a couple of extra ones.. what is the best way to do this without duplicating instance names, functions and variables?
View 0 RepliesI 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'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'm in the beginning stages of trying to understand AS3.Flash is outputting these two errors:1118: Implicit coercion of a value with static type Object to a possibly unrelated type Function.1120: Access of undefined property event_obj.

What if I want to pass a parameter to the traceMe function? There is a way to do that?

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 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
}
[code]......
Seems like in AS3, I can in theory, delare arrays that can only contain certain data types:
private var my_array:Array.<String>;
produces this error:
1199: type parameters with a non-parameterized type
however
private var my_vector:Vector.<String>;
is just fine. Is there a way of making this work with an Array?
The compiler keeps yelling at my first line "package aRenberg.utils", and I don't see anything wrong with it.
what this error even means? I'll upload the code if needed, and I'm using a heavy amount of ASDoc if it makes any difference.
EDIT: I might have isolated it. If I comment out "import flash.utils.Dictionary;" the error goes away, and it moves on to other errors, however, one of the errors is "1046: Type was not found or was not a compile-time constant: Dictionary."
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:

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.
