ActionScript 3.0 :: Can't Set Vars For Functions Of Event Listener
Feb 9, 2010why can't we set vars for functions of a Event Listener. To be more specific, this is my code:
Code:
package
{
import flash.display.MovieClip;

isit possible to call two functions from one button event listener?
or is it even possible to write two seperate listeners for one button that listen for the same thing an example is shown in the code;
also, i have string variable, that i want to use to call a certain funtion depending on the variable, for example the vairables name is phase_no can i do next_btn.addEventListener(MouseEvent.CLICK,nextPhase,beginSubmit+phas e_no)??
Code:
trace("Hello!");
I'm up late coding and I've come to a halt here's why:
I'm looking (desperately) for something that will explain why my "public class marquePage" is not working properly. I don't have access to the actual file right now - on a friend's computer - but i'll try and make this clear, here it goes :
Code:
// example : (having declared the namespaces at package level and embedded the pictures in separate classes "photosMP", etc)
public var ceNom:Namespace;
public var cetteListe:Array = [photos, dessins, livres, maous];
[Code].....
Somehow, the event listener doesn't want to know about namespaces... in fact, everything comes up ok except that when you click on any of the bookmarks (cetMP), nothing happens at all
this is the error I am having:
TypeError: Error #2007: Parameter listener must be non-null.at flash.events::EventDispatcher/removeEventListener()
at project1_fla::MainTimeline/btnName()
here is my code:
ActionScript Code:
import caurina.transitions.Tweener;
import caurina.transitions.properties.ColorShortcuts;[code]..........
PHP Code:
function finale(){ finalFunc = "section" + _root.selectedSection finalFunc();}_root.selectedSection = 1finale();function section1(){trace("moo")}function section2(){}
how can i call public functions or vars of a sprite class from another class (or frame script)? i keep getting 1061: Call to a possibly undefined method getSide through a reference with static type flash.display:Sprite.
//Framescript
var a:Sprite = new customRect();
addChild(a);

since i started using Flash Builder (Flex 4) i could see that it can auto-generate some handlers for example if i have a <s:Button> and i add a click="" i get a hint of "Generate Click Handler" and when i click Enter he writes this code:
Code:
protected function button1_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub
}
Now i knew about public and private things(functions/vars) and if a function was public i could execute it form outside of the class and inside. But if it was private i could only execute it from inside of the class and i couldn't execute it from outside of the class.
So anyway, what does "protected" mean? what does it do?I was thinking that if i load a SWF in my app I can go inside of that SWF and execute functions, read values from variables, or anything like that ... and that seems like a security problem ... So i was wondering if the "protected" keyword could help me with this security problem. And if not, I would like to know what is it good for
Lately I changed Flash CS3 for CS4. In older version classes written by me worked fine. However, in CS4 I have serious problem with them. Compiler states that part of my functions and vars are undefined, which is not true. I tried everything - changing name of class, functions, moving class file to different directory, removing package. I even counted { to check if they have pairs. I'm really out of options what can cause those errors.
Here are error given by compiler:
1120: Access of undefined property mnChangeMan.
1120: Access of undefined property ChangeManSliders.
1120: Access of undefined property ChangeManInput.

i am builiding a photogallery where at each stage i load six thumbnails. Each "placeholder" is initially set to 20% xscale and yscale and when each thumb has fully loaded, i want to have the thumb tween from 20% to 80%. The jpg thumbs are loaded inside the placeholder.when the thumb has fully loaded, goodToGo = 110 and so i want to trigger the AS tween.[code]to get some idea of how it would look, check out URL...and click inside any of the collections.
View 1 RepliesCould anyone suggest how to fix the function at the bottom so that when button forward_btn with label "Go to next Training Point" when clicked recalculates the fields created in function fileLoaded.[code]

I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
View 3 Repliesif I have an event listerner (mouse, keyboard, enterframe,....event) that is being triggered, and when it finishes its event, something that is able to detect the finished event listener and fire out another sets of event.
It works more like MOTION_FINISH in TweenEvent, but it is only available for TweenEvent only, what if I want to detect a mousclick, keyboard, enterframe or even touch event?
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.
View 3 RepliesI'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 RepliesThis 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:

how can i access event.target outside event listener method.say for example
my_mc.addEventListener(MouseEvent.CLICK, onC);
function onC(e:MouseEvent):void
{
var m:MovieClip = e.target as MovieClip;
}
trace(m.totalframes);/// not working
now what if i want to get totalframe property of m instance, in short for every movieClip clicked.
I am doing this inside a module containing viewstacks and their childs.Calling onInit() on creationComplete of module.When I am inside one of the childs of a viewstack of this module and press Enter, it doesnt not invoke the listener function at all (bp inside this does not get hit).
private function onInit():void{
this.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
}[code]..........
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.
I have these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:
test01.abtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.bbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.cbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);[code]....
It is only targeting the movie clip, not the buttons inside the movie clip.
how to add an event listener to an event from a custom class. Here are the relevent lines of code (I think) from the class:

I have a code in AS3 that works when you rollover it. I need to use the same code but not with an eventlistener for a mouse event but a frame event when the timeline plays the clip
var coordX:Number = shaker_mc.x;var coordY:Number = shaker_mc.y;var timer:Timer = new Timer(10); shaker_mc.buttonMode = false; shaker_mc.addEventListener(MouseEvent.MOUSE_OVER,startShake);shaker_mc.addEventListener(Mous

printableInvoice.addEventListener(batchGenerated, printableInvoice_batchGeneratedHandler);Results in this error: 1120: Access of undefined property batchGenerated. I have tried it as FlexEvent.batchGenerated and FlashEvent.batchGenerated.
The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
Reference objects on stage/frame from document class. AddFrameScript seems to do what I need it to, except for one thing. In the function I'm passing to be added as a frame script, I want to dynamically create some event listeners for buttons, but variables I want closed over the listener functions aren't behaving as expected -- they all end up having the last assigned value of the variable rather than the value it had when the function was defined, as if different scope rules are in effect than normal:
addFrameScript(node_frame - 1,
function() {
stop();
question_txt.text = node_question;
answers_xml = node_xml.answer;
[Code] .....
But then afterward, if I click any of the three buttons, they all trace:
3A
Do frame scripts observe different (dynamic rather than lexical?) scoping or something?
Basically what I want to do is call a function attached to an event listener, without the event actually happening - for example:I have a function that is attached to Event.RESIZE.I would like to call that function from time to time, but this function of course requires an Event argument, so attempting to just call the function throws an error that it expects 1 argument and got none.
View 2 RepliesI have what I think is a scoping issue with a listener. I have a movie clip which contains several picture management functions. I want to add a listener to it so that the next image loads before it is processed. Where do I put the listener - In the MC or in the root? At the moment, I have it in the MC but it does not run the function. I created a test function in the root which runs the listener no problem.
View 2 RepliesI am currently having a mc in my library use a class. The mc is duplicated and put on the stage. Inside the class the mc gets a rollover state. Problem is that, although the rollover listener and function 'works', any action that is given is applied to all objects linked to that class.
Code:
Select allpublic class cities extends MovieClip {
private var theStage:*;
public function cities(cityid:int, cityname:String, mymc, ref:*) {
theStage=ref;
this.alpha=.85;
this.buttonMode=true;
[Code] .....
So pretty much on rollover on one of the mc's makes them all alpha = 1 and rollout makes them all alpha = .85 instead of the one being rolled over. It does make sense I guess because they are all calling that same function I think. I also tried referring to the specific mc (mymc) instead of the parent and this.
