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.
View 3 RepliesI 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'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?
Is there any way to list all listeners to an EventDispatcher instance, or at least list all event strings that are being listened for?
I know there is a "hasEventListener()" function, but you need to know the string you pass in in order to check for it. I suppose it would be bad coding ethic, but it can have its uses. (Am I making myself clear enough on what I am looking for?)
Also, how are eventListeners speedwise? Since there is a lot that needs to be accomplished when dispatching and listening for events, would it be a bad idea to use an Event system for such potentially CPU heavy items as collision detecting?
Some of my flash buttons do not work in FlashPlayer 10 but work in 10.1 So I wanted to alert a user to upgrade to the most current flash player 10.1 if he/she has 10 and visits my website. What is the best way to do it? My entire site is done in Flash and I am using AS3.
View 1 RepliesI was able to gather info on how to test and display users OS and FP version. However this info is "dormant" it is just being displayed on the screen.Does anyone know how to make an alert message to upgrade to the current Flash Player if a user runs the lower version?
View 1 RepliesOK, 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?

Is it possible to add a child to the current frame only?
I know you can just remove/hide them, and generate/show them again.
But isn't there an easier way?
What's the sanest way to achieve something along the lines of this.gotoAndStop(this._currentframe)?
What I want is that Flash re-loads the current frame as if I was using gotoAndStop (which does nothing if it is given the current frame as target frame).

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.

View 2 RepliesI'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) {
[code]...
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..
I'm trying to remove all the event listeners from nextBtn. the names of all the possable callback functions are stored in mdpArray. I want to use the for loop to remove all the listeners from nextBtn. the error message says
cannot convert "mdp1_1" to Function
How can i make this work.
Code:
var mdpArray:Array = ["mdp1_1","mdp1_2","mdp1_3","mdp1_4","mdp1_5"];
private function clearEvents(nextBtn):void{
var _nextBtn = nextBtn;
for(var i:Number = 0; i<mdpArray.length; i++){ _nextBtn.removeEventListener(MouseEvent.CLICK,mdpArray[i]);
}
}
First, when i print my movie(properties 760 x 520) it is very small on paper. How can i make it fit the paper?
Second, how can i only print the current frame or what is on the screen from flash?
We have noticed a possible bug in the Flash Player within Mac's latest OS version Snow Leopard.
When a Browse for file dialog is initiated, upon returning to the browser. It's as if there is a layer above the flash app which stops interaction with the mouse. MouseOver events no longer take place and a click is require to remove this layer. If you move your mouse at all after the click this invisible layer returns limiting interaction.
We have tested this with 2 macs running snow leopard and the latest Flash Player. And also verified it is not an issue on Mac OSX previous to Snow Leopard.
It seems to effect only FF and Safari. Opera functions correctly.. Here is a video we created documenting the problem: [URL]
We have not had any customers complain about this yet. But if it's infact a bug, it's just a matter of time.
I'm creating a new look for the xspf player: [URL]The playlist highlights the current song being played. I'd like to change the color but can't find where that option is listed in the .flv file, or in the actionscript file.
View 2 RepliesI'm trying, to remove and then reassign an MouseEvent.CLICK to a on stage button, using a second on stage button.
when first button is released, it works fine, but when 2nd is released, the 1st one MouseEvent should be cleared and re-assigned a second listenner.
example code
bt_ok.addEventListener(MouseEvent.CLICK, log_in);
bt_pesquisa.addEventListener(MouseEvent.CLICK, pesquisar);
//
function log_in(e:MouseEvent) {
[Code].....
circDraw.addEventListener(Event.ENTER_FRAME,function(e:Event){expand(e .target); },false,0,true);
function expand(obj):void {
obj.height+=3;
obj.width+=3;
How would I add a line here to remove that event?
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();

View 4 RepliesI load into an empty movieclip (via addChild) a library object (a movieclip of class MyObject that extends the MovieClip class). At some point, from the main I remove this custom movieclip from its parent and I set any reference to null to completely destroy it. The question: what if in the custom movieclip class there are eventListeners? Are them deleted when I destroy the object? Should I write a method to remove them before deleting the object?
View 3 RepliesI 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?

I have a mc that i use as a button. I have an external class that controls the button and adds interactivity to it, here's part of the code:
[Code]...
The problem is, i want the btn that, when clicked, remain inactive.That's why I remove all the listeners in the class. HOWEVER, it still functions as a button, I mean the functions haven't been removed at all after I click it. What's wrong here? Why are the functions still there, if I have removed them when clicked at the btn?
