ActionScript 3.0 :: Frame Of Nested Object - Remove Only The Event Listeners From Objects Only On Frame 1?
Jan 21, 2011
I have 3 frames each with a movie clip called map_mc. Each different map_mc have different objects that call the CollisionDetect class. Heres whats happening. objects from frame 1 will start freaking out when I goto frame 2. How do I remove only the event listeners from objects only on frame 1?
I have been trying this.currentFrame but the problem is that all the objects are inside map_mc on the first frame so no matter what it will always be 1. On the other hand MovieClip(root).currentFrame will always give me the current frame but wont tell me what the objects frame is relative to the stage.What I want to do is have something to this effect:MovieClip(root).this.currentFrame would output that this object is on frame 1 and MovieClip(root).currentFrame will tell me that the stage is on frame 2 so I can remove the listeners accordingly.

I have a movieclip that contains two frames, each frame contains a different set of buttons.
it seems that i cannot add the event listeners to buttons that are not in my current viewed frame.
so.. problem one: is there a way to add event listeners to all the elements in the movieclip even if the elements are in a different frame.
problem two: after I added an event listener to some elements in current frame and then I move forward to the next frame and go back to the same frame, all the event listeners are removed and i need to initialize them again. is there a way to resolve the issue without the need to re-initialize the event listeners ?

I've got a project I'm working on that has two frames in the main timeline and on the second frame there is a movieclip (pages_mc) with 7 frames to it, each containing content (more movieclips, text, graphics, etc). I set it up this way because I have a title bar and navigation buttons on the main timeline I want to always stay on top of everything.If I have actionscript on an individual frame of pages_mc, that controls buttons on that frame, do I need to remove the MouseEvent listeners if the user navigates to a different frame? I've read that if you don't remove them it will eat up memory and cause poor performance.
I already ran into a problem with the ENTER_FRAME event listener, in which I was forced to remove it because it would just keep going even when the user navigated to a different frame of the pages_mc movieclip.Just didn't know how much of a problem this would be. I'm thinking that if I don't remove them, every time the user goes back to that frame it's just adding another MouseEvent listener to the buttons. Is that correct?

If you dynamically create a parent movieclip, and dynamically add a color picker to each clip, and add an event listener for each color picker, does a removeChild on the parent movieClip remove event listeners belonging to any of it's children?

I'm having problem with garbage collection in a large, not-so-well-written project that I didn't start. I am getting memory leaks -- and want to make sure that all event listeners on the offending objects are removed. I've gone through the code and done what I can, but still ain't happening -- is there a way in AS3 to take an object and see IF it has an event listener, and to REMOVE that listener -- that is, to remove ALL listeners, without knowing what they are? I know if I know what the EVENT TYPE is then I can use hasEventListener() to figure out if it has a listener of that type (although the presupposes I know all the event types being used), but if I don't know the function that it's subscribing to then I can't remove it.
Or is there some other way to simply nullify an object for GC? I've changed all listeners to weak -- but I think (since the offending objects are FLVPlaybacks) that something in the flash internal setup is still listening to my object (I've gleaned this from FB 4 profiler which I've used in external mode). I would just, at this point, like to see what's going on.

If I have 5 frames and each contanins a MovieClip on stage that includes it's class, listeners, functions etc.If I go from one frame to another,should I clean everything up? I mean remove listeners, remove childs etc etc.Or other MovieClips except those in the current frame are ignored from flash player.

Lately I've found myself constantly writing removeEventListeners everywhere, which makes code quite messy. I know it's a best practice and such, but in general it has no sense. Garbage collector should handle such a simple task by itself, shouldn't it? Is it that hard to remove all listeners automatically when object is set to null?
So I just want to be sure if that's the case. Does setting an object to null, automatically remove all attached event listeners? In my case scenario is like this - I create an object and attach bunch of event listeners to it, then after a while I need to re-initialize this object. Of course setting this object to null is much easier then unbinding every listener by hand. And on most part listeners are anonymous functions, which means that it's not possible without code refactoring. When I simply re-initialize a variable with new I do not get duplicate listeners and such, but I'm not sure that it's previous value, along with all the listeners gets garbage-collected. Is it?

I want to make a static function that I can use in all the custom classes.It should be some kill(); function that would remove the object from the stage as well as removing its event listeners. I made it in Document class, and it didn't work. Here's the code:

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??

I'm working on a gunslinger game. I have numerous frames which correspond to different stages of the game. The frame that corresponds to the actual gameplay has a really involved ENTER_FRAME function attached to particular item on the stage. When the game is over (or an error occurs, or the network connection fails) I want to leave the gameplay frame and move to some other frame. When this happens, I would like the ENTER_FRAME function on the gunslinger to be removed because the player may finish a game and then re-enter the gameplay frame later after selecting a new opponent.
QUESTION: Can anyone recommend a good way to manage the keyboard event listeners, all the button event listeners, etc? As you might imagine, I have no reliable way to determine which frame might be entered after the gameplay frame because the frame change could be triggered by a variety of different reasons.

I am using Adobe Flash Professional CS4 with all the latest updates. The FLA is an Actionscript 3.0 file. I am creating a basic flash site with several pages that change when the user clicks links on a left side navigation bar. on the pages are sub tabs that change out different content(text) based on what the user clicks on the current page. when they click a button it triggers an event listener, the event listener runs its function which changes the definition of an already defined (String) variable, and the page goes on to a frame checks what that variable is and then leads the movie to the correct frame that the corresponding content is on.
here's the issue: it works perfectly the first few times, and then the event listeners stop working, first one of them, then all three once i click one of the two available. i started this site before i even knew what a class was(regretably), and all the code is on the timeline in different frames.

OK, I am trying to get the following functions to load and unload the video to my main timeline when I go in and out of a frame. I tried on Enter_FRAME but it is now working properly and load many instances.
What are the listeners I need to do to call the functions of oCoach when enetering a frame and fclickCV when leaving a frame?

I have an problem whereby I have created a Frame by Frame dancing human figure and now I want to move it across the screen as well as scale it using a Tween.
I have spent quite some time slightly adjusting the upper arms, forearms, hands, legs etc and creating a new keyframe for each movement. All the movements are all in one layer... ie the forearm doesn't have it's own layer etc. I am running the animation at 24fps so there is quite bit going on.
I now realise that I should have created a symbol/movie clip from the first image I created and then scaled and moved the image first before animating it's limbs but I only realized that after hours of work and I would hate to start all over again.
So basically what I have is a dancing human figure in the one spot moving it's arms and legs and I want it to move across the screen and become larger by scaling it using a Tween. I could of course re-edit each keyframe by slightly scaling and the slightly moving the figure but that will take quite some time to get right as there will be a fair bit of trial and error doing it that way.

I have two movie clips. The child movieclip is a button with rollover events which is nested inside the parent. I would like the parent to also have rollover events, but I understand that this is not possible in flash. I am familiar with two workarounds: event bubbling/delegation and the event listeners.

Here's a hodge-podge of information:
Custom Event Class:
Code:
package com.events {[code]...
I made a custom loader to replace the urlLoader and even tried a replacement for the _loader using the same custom event.Works great for the first addEventListener:
Code:
urlLoader.addEventListener(Event.COMPLETE, onSwfLoaded).But stops on the second addEventListener.If I just apply the custom event to the following...
Code:
_loader.addEventListener(Event.COMPLETE, onLoaderInit);
VERSUS
Code:
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderInit);it works just fine.As soon as I use it on the contentLoaderInfo line, it throws that type error cannot convert CustomEvent to Event error.I also double checked that my custom event listener was overriding clone()properly and it looks like it does.

i have As code with functions on frame 1-6 i want on frame 7 to have a clear code that will remove all the functions from frame 6. I need only the AS code to be cleared on frame 6 no where else... so the functions that are there no longer work in the rest of the animation.

How do you know when you should remove event listeners? For example, I know that if I have a TimerEvent listener, I can safely remove that event when I have stopped and / or deleted my timer. Or, if I have a display object on the stage, and I remove it, I can safely remove any event listeners associated with the display object.

I've placed listeners on the var "topic_mc" (below), but I'm not sure how to remove them properly:
Code:
private function layoutTopics(modNum:Number, attachTo:MovieClip):void {
topicLength = MainMenu.modArr[modNum].topicArr.length;
if (Interface._ui != null) {

doesn't really work - the listeners keep running. How do I call the objects properly to remove the listeners?

is it necessarily to add and remove event listeners like so:
Code:
addEventListener(MouseEvent.MOUSE_DOWN,mDown);
function mDown(e:MouseEvent){
removeEventListener(MouseEvent.MOUSE_DOWN,mDown);
[code]....
assuming rapid input, is it really better to do this rather than just let the mouseDown and MouseUp Listeners run all the time? It seems like it would be strenuous to constantly add and remove listeners like this. But this is how i generally see it done..

What I am trying to do is, if a user presses keyboard (key 1), picture 1 should FadeIn and if a user presses keyboard (key 2) picture one should FadeOut and picture 2 FadeIn and vice-versa. With the code mentioned below it works fine sometimes if I am not pressing any other key while it is performing one action but sometimes it behaves weird also. What I want AS3 to do is not to take any action or in other words it should not listen to keyboard until it finishes the opening or closing animation of a picture or any other object assigned to the key.
stage.addEventListener (KeyboardEvent.KEY_DOWN, KeyDownHandler);
/**///keyboard keycode for 1 & 2var key1:uint = 49;
var key2:uint = 50;
var BG1:Image1 = new Image1();
var BG2:Image2 = new Image2();

I create a stage keyboard event listener in an externally loaded swf such as:
Code:
stage.addEventListener(KeyboardEvent.KEY_DOWN, onDown);
My question is how and where I should remove this event listener? I have added an unload event handler to the external swf like this:
Code:
this.loaderInfo.addEventListener(Event.UNLOAD, unloadHandler);
The unloadHandler code looks like this:
Code:
private function unloadHandler(event:Event):void {
stage.removeEventListener(KeyboardEvent.KEY_DOWN, onDown);
}
When the container swf unloads the external swf, unloadHandler() gets called, but with the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Where should the keyboard event be removed?
