ActionScript 3.0 :: Keyboard Event Listener Doesn't Call On Function
Jul 5, 2011
The keyBoard event listeners call on the rotate and unrotate functions and based on the key inputs(A and D) will implement either of the functions and rotate the image or return it to the original upright position. However, I haven't been able to get the function to work. When I press the A or D keys on the keyboard nothing happens. I even put trace() in one of the functions to see if the function will even be implemented but I don't get anything. I put in my Scripts below. Why are the functions not working? Do the eventlisteners fire or are there conflicts? I'm not getting any error messages.
ti.border = true
ti.addEventListener(TextEvent.TEXT_INPUT, onInput);
function onInput(event:TextEvent):void {
if(ti.text.search('a')!=-1) load_image("http://i54.tinypic.com/anom5d.png", "ottefct");
[code]....

I have this keyboard event listener to listen for key_Down of letter A and D but I end up with and error:
1119: Access of possibly undefined property A through a reference with static type Class.
When I use
function rotate(evt:KeyboardEvent):void
{
if (evt.keyCode==68) {
evt.currentTarget.rotation = 90 }

Is there a reason why a keyboard event listener would not work if the flash is embedded in an HTML? The rest of my game is running fine in the background, but I can't launch the movieClip "nextCar." My code is below, if that makes any difference...
function goNow (event:KeyboardEvent): void { thisOtherKey = event.keyCode; if (thisOtherKey == 32) { nextCar.gotoAndPlay(2); parkingQue.play(); tries++; }}stage.addEventListener(KeyboardEvent.KEY_DOWN, goNow);

Say I have the following function
Code:
function myVideoFunction(event:VideoEvent):void {
do some stuff....
}
but i want to call it from the event listener
Code: button.addEventListener(MouseEvent.CLICK,myVideoFunction);
I cant because it runs off a VideoEvent, not a MouseEvent.The obvious work around is to copy and paste the function and rename this part, or alternativly just make a function such as:
Code:
button.addEventListener(MouseEvent.CLICK,callMyVideoFunction);
function callMyVideoFunction (event:MouseEvent) {
myVideoFunction(null);[code].....

I am loading 5 images using "for loop" and I have created the listener and if the images completes the loading, the function is called. Now, I need is the name of the "image" which is loaded on each five images gets completed.
[Code]...
in the output it is throwing as "[object LoaderInfo]". Now i need is the name of the "Image", inside the thumbnail_load function, that means, which image loading is completed.

this.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);

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.

I have a document class called Main.as In the class constructor I have the following listener:
enter code here
var listeningFORModeChangeToStudent:Sprite = new Sprite;
listeningFORModeChangeToStudent.addEventListener(TellAllModeChangeToStudent.STUDENT,exp);
addChild(listeningFORModeChangeToStudent);
[code]....
In a third class I make a call to the despatcher in the previous class:
enter code here
var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent;
ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?

Atm im putting a a game i build into my main flash app.Everything works fine except the keyboard listener.unny.AFTER a mouse click on the 'loaded' swf the keys 'arrow UP' + 'arrow DOWN' start working.I created already a script that loads the listeners IF they are not loaded yet, but i think thats not the problem. Same situation.After clicking on the movie it starts to work, but apparently the listeners are already applied. All other listeners work besides the keyboard listeners.Stand alone(the game swf running by its own) the game works perfectly!btw the game is importing a main document class.
Code:
this.addEventListener(KeyboardEvent.KEY_DOWN
var keybListenerLoadedUp:Boolean = false;

Just using the script below to output the key that is pressed in the output but I get the "Cannot access a property or method of a null object reference." warning on the addEventListener line, which I assume is because of the "stage" var. How do I correct that?

my event listeners does not catch a custom event while all of the others do. I have this in my FLA:
[Code].....
...which obviously means p5.finished() executed AND NGDemoEvent successfully fired the custom event. But I don't get the trace from closeP5Handler() (and obviously not from closeP5).
My FLA file has six other such function calls to six other classes (P2, P3, etc.) and these all work. They're identical. I'm tearing my hair out over this. Why won't the listener get the event?

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):

I'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.

I have an eventListener that is listening for the end of an audio channel that is playing an external MP3:
ActionScript Code:
d1Channel.addEventListener(Event.SOUND_COMPLETE, soundComplete, false, 0, true);
function soundComplete( e:Event ):void {
[Code].....
This works beatifully when I am running a test movie on my computer, and even the fully published SWF. But when I load it on the web server, and run it in a browser. This doesn't do anything. Once the audio is done, nothing happens.

I have a movie clip being dynamically added to the stage via an AS3 linkage call:
gameOver_mc = new GameOver();
stage.addChild(gameOver_mc);
The movie loads as required.But when the movie has been added I want the user to be able to press spacebar and a function to run.So in the GameOver.as class I wrote the following:
Code:
package
{
import flash.ui.Keyboard;
[code]...
But as soon as the movie clip tries to load I get the error message: TypeError: Error #1009: Cannot access a property or method of a null object reference.I would have thought this would work fine. When I trace the statement in the Constructor function is works. Its only when I try to add an event listener that I get the problems. So am I not allowed to add event listeners from a dynamically loaded class?

I have a movieclip with 3 frames. each frame has a button on it. Using actionscript I jump to a frame then add an event listener to that button.However, it doesn't work since the playhead for that movieclip doesn't actually get moved to a different frame until the frame redraws. So actionscript says the button doesn't exist.(other than not dynamically adding the buttons with code... which will be my next step...)

I've been lookign around for this but cant seem to find how to do it. How do you make a array of buttons then call it in a event listener? The idea is that I don't have to creat code for each button. it can just run it over for each button.

I'm working on a game that involves some timed animations and I need to fire a kind of 'failed' event.Basically I'm moving a clip from one point to another on the stage, the user has to input a correct key combination before the endpoint. I'm capturing the inputs correctly, but I need a default procedure to fire if the player doesn't input anything at all.So I'm guessing that at the endpoint I could check if my function to capture the key inputs was actually called, and if not, call the 'failed' procedure, or if at the endpoint, no keys were pressed, do the same
