Actionscript 3.0 :: Professional : Removing An Event Listener In Code?

Mar 20, 2012

i have a movie clip named "contact" inside this movie clip made the same object into a 2nd imbedded movie clip named "em_contact" inside this I did a frame by frame animation and added a new movie clip symbol of a piece of paper named contactbtn_mc on this frame, I added an event listener for a click that acesses on the root level a symbol named contact_mc i told it to go to and play frame 2 that plays out an animation of this object moving into the screen.

my problem here is i asked earlyer on how to stop the em_contact to stop listening for the mouse click once it is clicked. I made the code it come up with no errors but it does not stop the event listener the event listener is still there bellow is my code.

import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
import flash.events.MouseEvent;

[code]....

what i want to happen here is for the event listener once it is click to stop listening for that event becuase i have a mouse event inside the "em_contact" movie clip on an object named "contactbtn_mc". and that one has a click event on it as well but when i click on the contactbtn_mc the animation above plays out as well.

ActionScript 3.0 :: Removing An Event Listener From A Function?

Mar 15, 2010

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.

The problem is how to remove the event listener later in the program as the usual code isn't working. I'm guessing I should have done this in a class but I'd like to understand this problem better.

Professional :: Removing Event Listeners On Leaving A Frame

Mar 15, 2012

I have l modded some code that I am really happy with, it makes buttons bounce around for the user to try to click on when entering a certain frame.. I notice tha the code adds eventlisteners ENTER_FRAME to make this work, when you leave that frame there are now problems with null objects becuase the listeners are still on but the objects are not there anymore..
 
Ok so attempted solution - I can use a currentLabel on the main timeline to check if the correct frame is reached then use a function if (label is x) put listeners on else take them off... works but then I have to have these objects hidden on the timeline  and then add visible=true/false to my framelabel listener.. This works but part of my functionality here is that these movieclips that move are buttons that the user clicks on and they explode and dissapear- but now they dont because I have a code that says on that frame they should be visible..
  
The only thing I can think of is to have a blank frame at the end of the explode and put a stop on it.  Then add a gotoAndPlay(1) into my frame label code.  Seems very ugly, you guys got a better way?  Can I remove eventlisteners on leaving a frame?  Is there a code like LEAVE_FRAME??

Professional :: Target Event Listener When Loading External SWF

Jan 22, 2010

I'm looking for an alternative to using:
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyFunction);

The problem I am encountering is that eventListener above works fine on its own(stand-alone swf), but when loading an .swf externally into another .swf, the listener fails with the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

How can you target the event listener when loading as an external .swf differently?

ActionScript 3.0 :: Proper Listener On Tween Event Inside Mouse Event

Feb 23, 2011

My stage has about 25 buttons on it. Each button when pressed to tweens the background to some random x/y coordinates and then loads an external swf file.This is all working, but the timing is off. How can I wait for the initial background tween to end before I make the loader call to the .swf file.Currently each button's behavior is called on the MouseEvent.CLICK event which calls a function that knows its unique filename.swf. I know you can add the MOTION_FINISH even to the tween event but then I would have to call a new function and lose track of the button that initially called it.

ActionScript 3.0 :: Basic Event Listener Mouse Event ROLL OVER

This is a very basic question but I can't seem to find an answer. I have a mouse over event and have created the buttons with the mouse overs which is working great. I created the actionscript to go to a specific web page when a user clicks the button. Now, I need to add a label to the mouse over so when someone mouse's over any area of the button, it will show them a particular name for the button.

I am sure that this can be done using actionscript in a mouse event roll over command but I can't figure out what I need to show the text. Here is where I am:

Actionscript 3 :: Use The Same Event-listener Callback For Multiple Event Types?

Nov 18, 2011

This might be more of a subjective question, but is it generally best practice to have one dedicated method per event-types that you add an event-listener?

Such as:

myButton.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
myButton.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
//Somewhere else in the code...

[Code].....

And if you had a MouseEvent.MOUSE_UP, MouseEvent.MOUSE_DOWN and other relevant MouseEvents event-listeners to watch for, you could even set a switch statement to handle all the various MouseEvent types.
