Here's the code
public function onKeyPress( keyboardEvent:KeyboardEvent ):void {
if (keyboardEvent.keyCode == Keyboard.A) {
//DO MY STUFF NAO
}}
Error:
1119: Access of the possibly undefined property A through a reference with static type class.
When I put Keyboard.RIGHT or Keyboard.SHIFT etc. It works fine. I tried it with keyboard.Event.keyCode == 97 and such and it still didn't work.
I have been been testing for keyboard events one key at a time. Now I want to test two keys being pressed or released at the same time. I am unclear on how to do this. Do I need to indicate this intention in the functions parameter
Code:
if(event.keyCode==keyboard.LEFT&&keyboard.keyCode.RIGHT);
isn't cutting it.
I created an array with movie clips now how can i target one movie clip with event handler function . so that when i clicked on one movie clip a message should be displayed
View 4 RepliesIn frame 1 I set a keyboard handler on the frame:
stage.addEventListener(KeyboardEvent.KEY_DOWN, moveRusty);
moveRusty() moves an icon back and forth when the arrow keys are pressed - very simple. From frame 1 Flash proceeds to frame 2 where the main action takes place - rusty moves just fine. When he reaches a certain point I gotoAndPlay frame 3 which sets rusty's visibility to false. A button in frame 3 has gotoAndPlay frame 2 where everything is reset and Rusty is free to move.
The problem is, Rusty stops moving when we go back to frame 2 from frame 3. I put in a trace statement into the keyboard handler and it never gets hit. Now the REALLY weird part is that if I move the focus from the flash window to any other window and back again, things start working. From then on, everything works fine until I go to frame 3 and then back to frame 2 via the button in frame 3.
What kind of behavior would Adobe build in so that keyboard handlers only worked after change focus away and then back?
In AS2 we can add additional event handler on same event as below code does.
on (rollOut, dragOut) {
// Statement 1
}
Now , I am workin in AS3 . So, how to add additional event handler on event in AS3
Let's say display Object's instance name is "myBtn"
Here I have include only Mouse Out only, Now I want to add additional event handler
myBtn.addEventListener(MouseEvent.MOUSE_OUT, myBtnEvent);
myBtnEvent(event:MouseEvent):void
{
// Statement 1
}
I have an event listener for a custom event type. This custom event overrides the clone method as required.In this event listener I want to dispatch an instance of a different type of event... a different custom event instance altogether. It also overrides the clone method as required.The problem is I'm getting a type coercion error: TypeError: Error #1034: Type Coercion failed: ...I do not know what is trying to do the casting. My code is:
/* elsewhere in a method */
addEventListener(GestureEvent.GESTURE_SCALE, handlePinched);
/* the event handler */

I am writing a program that needs to go to a random frame after clicking a button. However, the program also needs to start on a random frame. When I call the function at the start of the program it gives me an 1120: Access of undefined property event error. The function is originally written as followed:
function randomMatchedTrial(event:MouseEvent) {
... lots of code that probably doesnt matter, but let me know if it does...
}
the program starts by calling the function as followed:
randomMatchedTrial(event)
Can event handler functions be called outside of the event listeners they are handling?
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 RepliesI have 2 scenes. In both scenes, I have a movie clip that moves via keyboard control. If the goto next scene is triggered by the movie clip in the first scene the keyboard control works in the second. However, if I use a button to move to the next scene then there isn't any control over the movieclip in that scene. I've traced the keyCode in the second scene and it is picked up but the switch statement doesn't run. I'm migrating to Actionscript 3.0 and updating something I created in 2.0. I would like to do it without writing a class.

i have a question to ask about asynchronous key controls This was what i did
[Code]...
and i checked with [URL]...?newspage=6249 and it looked more or less the same, so why is it that when i move my character and when i hold down a key, it just keeps on listerning to that keypress event listener, instead of just executing the other event. So say, i tap left and after which i tap right, it will work just fine, but if i hold left and tap right, the event listerner will still be listening to the left key. So, i was wondering could anyone point me in a direction as to how should i make my code stop listening to an event as soon as another event has been dispatched?
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).

I have a question about making a function for two different kinds of event. It's not critical but I would like to reduce my lines of code and just be more efficient. Basically I have a button on the stage called "Enter". I also want the user to have the option of hitting the enter button. I don't have a problem making these two separate handlers for these events (i.e. one handler for the KeyboardEvent and one handler for the MouseEvent):
[Code]...
how can you switch the mouse event with keyboard event in the folowing example:
Code:
var qno=0;var rnd1; var rnd2;
tick.visible=false;cross.visible=false;
var right_answers=0;var wrong_answers=0;

i know that u have too define key up and down functions and in the beginnig give the keys we are using the false value, but how to make it that after i pess of a key you cant press in again unless you go to the next question that is the enable_disable in the following code. How would that function looked in case of keyboard event
What methods do you use to unit test event handlers, particularly if they require information from the event (such as mouse coordinates, or the target of the event)? Is the most common practice to just refactor the behavior into a method that does the lifting while the handler just extracts information from the event, or are there effective ways to simulate event dispatch in FlexUnit or Fluint?

We (AS3 coders) all know that one of the great things about the AS3 event model is that handlers are scoped to their containing objects. I'm writing an EventDispatcher for JavaScript, and trying to achieve the same effect.My question could be answered in a couple different ways:A: How does ActionScript 3 set scope within an event handler to the handler's container object, rather than to the event handler's caller (the IEventDispatcher on whom dispatchEvent() was invoked)?

I'm using a progress bar component in a movie clip and this progress bar works loading an external movie clip. However, once the external clip is loaded, it seems the "complete" event is not registering with the object listener. This is what I have:
ActionScript Code:
this.createEmptyMovieClip("FOB", _root.getNextHighestDepth());
var progressBarListener:Object = new Object();[code].......
The code a little more complicated than this in that there is an array that stores some information and a setInterval command that calls the loadContent function loading each external movie clip. I can past the entire code if necessary.Also the progress bar component is set up as thus: in the main movie (root) there is a movie clip called progressBar. Within progressBar the component resides with a variant name of PB.For some reason, when the external clip is finished loaded, the progressBarListener doesn't seem to be called.
I'm trying to find a way that I can control how a flash movie handles the click event from the HTML page outside the movie.
I run a website where we have advertising space for Flash Ads provided by our customers which, when clicked, open their own website in a new browser window (i.e. target='_blank') - however this causes us a few issues:
1.) We want to track the success of their ads, so we give them a custom URL that their ad should link to instead of linking directly to their site. This URL logs the click before redirecting the browser to the customer's website.
2.) Often the flash files we get use GetUrl() which seams to trigger the popup blockers in IE 7 & 8.
These two points mean we have to provide them with the custom URL for them to include in their flash ad, and/or tell them how to set up the movie to handle the clicks in a way that doesn't trigger the IE popup blocker, and this doesn't make it as seamless as it should be to place an ad on our site.
So, what I'm trying to do is find a way that I can reference the Flash movie object with JavaScript (or similar), and set the click event to open up a specified URL - so if the customer's flash movie doesn't have the right URL set in it, or is triggering IE's popup blocker it doesn't matter because when we display it, we can modify the event handler to use the correct URL and to open up their website without tripping any popup blockers.
I'm editing an xml gallery.you can see how it works now here (thumbnails are different than images, cause it's just for the sake of testing now)[code]...
oki. this all works via for each loop which creates thumbnails dynamically. the event handler for the click on the thumbnail is inside the - also dynamically created via this for each loop - button over each thumbnail. more or less like this[code]...
and now: i'd like to add "next" and "back" buttons,so that the user doesn't always have to click the closing cross and go back to the thumbnails, but that he can also -once he selected an image - simply loop through the gallery image by image.
oki. so first i tried to get the name of the button clicked previously and store it in a variable, a thus this would tell which image should be loaded via loader (say, name instance56 means Image00002 was loaded, so if now user clicks next, Image00003 should follow) . but i'm simplytoo simple to get the variable out of the event handler and for each loop scope. i also tried to do it inside the event handler,but then it gets terrbily messy, and i can never force loader to load the right image.
I have one event handler for several object's events. I would like to pass a value through to the function from the event listener:
ActionScript Code:
function chkEmpty(event:Event){
if(event.currentTarget.text==""){
[Code]....
So I am trying to essentially have one class dispatch an event into the flow when it is added to the stage, and have another class catch the event, but I'm having problems. I set up a little test to simplify/display the problem I'm having. There are 2 classes, and then just some init code on the timeline.
ActionScript Code:
//code for box 1
package {
[code].....
Is there a way to get the handler(s) function(s) of an event listener?
I'm trying to find a way to remove them without knowing what they are.
For example:
ActionScript Code:
if (mc.hasEventListener(MouseEvent.CLICK)){
// this object has a MouseEvent.CLICK listener
mc.removeEventListener(MouseEvent.CLICK, null );
}
Instead of null, I was hoping to find some function that retrieves the handler function.
I have classes that need to communicate with each other, but are instantiated at different times.Therefore I feel I need to create a universal Event Handler that my classes can add event listeners to,and can receive dispatched events from.
