KeyboardEvent Help
Okay, I need to know how to use the letter keys, as in
abcdef.. to do simple things like advance a movie clip in
actionscript.. anybody have the code?
there's no "the code". you need to code for the specifics
that you want.
this is the basic code to use during production of your
project:
stage.focus = this;
this.addEventListener(KeyboardEvent.KEY_DOWN, keyDownF;
function keyDownF(e:KeyboardEvent):void {
trace(e.keyCode);
}

Std barcode reader - keyboardevent for stream of chars - help :(
Hi all,
It's the very first time for me in adobe forum so.. hi everyone
I've got a question related to my air application. This application has many controls like textinput button etc. etc.
I would like to catch a barcode (a very fast keyboard stream of chars) in the main application (this isn't a problem I already can do this) and, if it is a barcode then i would like to stop the propagation of the chars otherwise the propagation of the chars continue as usual
In order to catch the stream of chars I've used a timer, restarted every time i retrieve a character, if this timer expire and I have collect more the 5 chars I suppose the chars collected could be a barcode otherwise the chars (if they are less than 5) should be normal character from the user that use a keyboard
the effect is:
first case:
a fast keyboard chars coming (a.. ok this is a barcode)
stops the writing for example in the related textinput that has focus
elaborate the barcode
second case:
a character or two is arrived from the keyboard (ok this isn't a barcode)
continue with propagation and the related textinput show the character
is this possible?
I've tryed it.. but I can't find the solution, could anyone help me?
thank you
edit: if it isn't clear, please let me know, I can try to explain the problem in a better wayI tried to made some other test.
first test -------------
here I tried to record all the 3 events (i report only the script part)
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
import spark.components.Application;
var eventArray:Array = new Array()
var t:Timer = new Timer(5000)

NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_UP, appKeyUp, true);
NativeApplication.nativeApplication.addEventListener(TextEvent.TEXT_INPUT, textinput, true);
private function appKeyUp(e:KeyboardEvent):void
trace("appKeyUp")
var evttmp:KeyboardEvent = new KeyboardEvent(KeyboardEvent.KEY_UP)
evttmp = e.clone() as KeyboardEvent
eventArray.push(evttmp);
e.stopPropagation()
e.preventDefault()
private function textinput(e:TextEvent):void
trace("textinput")
var evttmp:TextEvent = new TextEvent(TextEvent.TEXT_INPUT)
evttmp = e.clone() as TextEvent
eventArray.push(evttmp);
e.stopPropagation()
e.preventDefault()
private function appKeyDown(e:KeyboardEvent):void

var evttmp:KeyboardEvent = new KeyboardEvent(KeyboardEvent.KEY_DOWN)

t.addEventListener(TimerEvent.TIMER, timerout)
t.start()
e.stopPropagation()
e.preventDefault()
private function timerout(e:TimerEvent):void
trace("timerout")
t.stop()
NativeApplication.nativeApplication.removeEventListener(KeyboardEvent.KEY_DOWN, appKeyDown, true);
NativeApplication.nativeApplication.removeEventListener(KeyboardEvent.KEY_UP, appKeyUp, true);
NativeApplication.nativeApplication.removeEventListener(TextEvent.TEXT_INPUT, textinput, true);
for(var i:int=0; i<eventArray.length; i++)
barcodeField.dispatchEvent(eventArray[i])

NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_UP, appKeyUp, true);
NativeApplication.nativeApplication.addEventListener(TextEvent.TEXT_INPUT, textinput, true);
]]>
</fx:Script>
the textinput event is never catch.
then I tried writing textinput event myself (in order to try if something appens) but I wasn't lucky
second test ---------
private function timerout(e:TimerEvent):void
trace("timerout")
t.stop()
NativeApplication.nativeApplication.removeEventListener(KeyboardEvent.KEY_DOWN, appKeyDown, true);
NativeApplication.nativeApplication.removeEventListener(KeyboardEvent.KEY_UP, appKeyUp, true);
barcodeField.dispatchEvent(eventArray[0])
var text:TextEvent = new TextEvent(TextEvent.TEXT_INPUT, true, false, bcd);
barcodeField.dispatchEvent(text);
barcodeField.dispatchEvent(eventArray[1]) -
Error #1009 in my Platform Game! Please Help!!!
In my basic platform game I have a "hero" that can walk and jump on the "ground." There is also a door to the next scene, which is the next level.The first scene works fine, but "TypeError: Error #1006: value is not a function. at Charles3_fla::MainTimeline/frame1()" pops up once in the output. It works however, and I'm not worried about it. The second I go throught the door though, Scene 2 opens, but then starts flashing as "TypeError: Error #1009: Cannot access a property or method of a null object reference. at Charles3_fla::MainTimeline/onenter()" pops up A LOT in the output. I don't know how to fix it, and would like help. P.S. I am using Adobe CS5 with actionscript 3
Here is the code for Scene 1:
hero.gotoAndStop('still');
var Key:KeyObject = new KeyObject(stage);

HELP! Uploading AS3 Game to server, no sound and Spacebar doesn´t work HELP!
Hello, relatively new to AS3 and flash, this is the first time i am publishing anything. We are trying to upload our simple flashgame to our webserver, the game works perfectly fine locally save for one thing. We get an error regarding TLF which says it wont stream or something. So when it gets online, no sounds play and spacebar doesn't work, left and right arrow does work. We have three TLF text fields that are used to update score, lives and show you final score. If i turn these into classical text they stop working.
Things we have tried: Changing default linkage from RLS to Merged into code, changing the text boxes to classical text(they then stop working), made sure the paths are correct(all files are in the same directory including the .swz file)
This is the code from the soundclass:
package
import flash.net.URLRequest;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.events.*;
public class MySound
private var bgSound:Sound;
private var fireSound:Sound;
private var waterSound:Sound;
private var earthSound:Sound;
private var lightSound:Sound;
private var soundChannel:SoundChannel;
public function MySound()
soundChannel = new SoundChannel();
bgSound = new Sound();
var req:URLRequest = new URLRequest("BackgroundSound.mp3");
bgSound.load(req);
//fire
fireSound = new Sound();
var req2:URLRequest = new URLRequest("soundFire.mp3");
fireSound.load(req2);
// water
waterSound = new Sound();
var req3:URLRequest = new URLRequest("soundWater.mp3");
waterSound.load(req3);
// earth
earthSound = new Sound();
var req4:URLRequest = new URLRequest("soundEarth.mp3");
earthSound.load(req4);
// light
lightSound = new Sound();
var req5:URLRequest = new URLRequest("soundLight.mp3");
lightSound.load(req5);
public function playBgSound()
soundChannel = bgSound.play(0, 999999);

public function playFireSound()
fireSound.play();
public function playWaterSound()
waterSound.play();
public function playEarthSound()
earthSound.play();
public function playLightSound()
lightSound.play();
I can somewhat get that sound can bugg out, but why does spacebar stop functioning? ANy help is greatly appreciated as this has to be delivered in twelve hours(published online) for a school assignment.Also might add publishing it locally in my own browser everything works, as does ofcourse playing it in flash itself. Changing from RLS to merged into code stops the error from coming, but doesn´t fix the problem on the server.

Help a newbie with Keyboard events
Right so I'm just getting started with ActionScript (and Flash) and I'm getting a bit confused. I've got quite a bit of experience programming in other languages but I've never touched either actionscript or flash before.
I've got various books and have tried searching around the internet but I can't find anything to help me with this problem... it looks to me like it SHOULD work (but obviously I'm wrong because it doesn't!) I'm just trying to get the base for a game set up, and want to be able to take in user input via the keyboard (I will want mouse control as well, but let's focus on this problem first).
My code is:
package {
import flash.display.MovieClip;
import flash.events.*;
import flash.ui.Keyboard;
public class Main extends MovieClip
var isRunning:Boolean = true;
public function Main()
trace("Flash Project!");
Initialize();
//Game Loop
while(isRunning)
Update();
trace("Exiting...");
public function Initialize():void
trace("Initializing!");
stage.addEventListener(KeyboardEvent.KEY_DOWN, OnKeyPressed);
public function Update():void
trace("Updating...");
public function OnKeyPressed(evt:KeyboardEvent):void
switch (evt.keyCode)
case Keyboard.ENTER:
trace("Enter!");
break;
case Keyboard.ESCAPE:
isRunning = false;
break;
case default:
trace("keyCode: ", event.keyCode);
break;
The errors it is generating refer to the OnKeyPressed function, and say that I have tried to access the undefined properties Keyboard, escape and default. I thought I imported all the keyboard stuff at the top? Help would be much appreciated here, I'll be fine once I'm up and running but at the moment I'm feeling somewhat lost.Right, well at least part of my problem was that I had
trace("keyCode: " event.keyCode);
instead of
trace("keyCode: " evt.keyCode);
but it still doesn't like the word "default"? This is strange as it's coming up in blue so it's obviosly recognising it as a keyword...
If I comment out the 'default' section of te switch case statement it get's stuck in an infinite loop, even if I press escape... which should set 'isRunning' false therefore exiting the loop...
Help! -
Hello everyone,
Currently if been busy with AS3 for a schoolproject however I'm facing all kind of problems.. If tried to contact a number of people for help, but neither they can help me with this. If searched my schoolbooks and of course the internet but I cant find anything about my issue.. Therefor I'm desperate and hoping someone on this forum is able to help me.
The current problem with my code is everytime I press the play again button in frame 4 and I restart my game it goes twice as fast. So I asked my teacher and she told me it's something with the EventHandlers but I didn't used them in my code. She's of no help to me currently.. Yes, education over here is worthless in a certain amount.. Personally I think to error lies in this code:
I also get the error called: TypeError: Error #1009 about a null object. It's at the MainTimeline/ enter_frame()..

If one of them traces undefined, it should isolate which object is the problem. If you describe what is involved with that object.child, then it may help generate an idea of what might be wrong. -
Is the help file wrong, or is it me?
Ok, so I am working through the help files, and am working on
"Enhancing the Hello World application", and I keep getting an
error message:
"1119: Access of possibly undefined property keyCode through
a reference with static type flash.events:Event."
Which is apparently having trouble with the following line of
code:
if (event.keyCode == Keyboard.ENTER)
The code is verbatim from the help file. I have checked
through and seen that keyCode does exist. Any thoughts?Reify32207,
> I keep getting an error message:

What you need, in this case, is an instance of the
KeyboardEvent class.
The Event class, alone, doesn't have a keyCode property, but
KeyboardEvent
(which extends Event) does.
> textIn.addEventListener(KeyboardEvent.KEY_UP,
keyPressed);
> function keyPressed(event:Event):void
That second line is the culprit. Should be this:
function keyPressed(event:KeyboardEvent):void

Help Needed With Scrollbar and Content
I'm having a difficult time with the Scrollbar component. I'm trying to have a scrollbar set up to navigate a text field or a MC of a text field. I managed to get it functioning within the desired frame, however when I jump to another frame, that very same content appears on the other frame, despite the fact that said frame did not have the scrollbar nor the content pasted within.
The bar seems to do what I want it to do save for the unwelcomed presence outside of the frame of choice. Here's the code I'm using. This is the keyframe code:
import boppreh.ui.Scrollbar
var scrollbar1:Scrollbar = new Scrollbar(boomboom, 500, true, false, 293, bar, slider, arrowUp, arrowDown)
addChild(scrollbar1)
scrollbar1.x = 50
scrollbar1.y = 50
And this is the code found in the AS file:
package boppreh.ui
import flash.display.*
import flash.events.*
import flash.geom.Rectangle;

import flash.ui.Keyboard

Any help would be appreciated. I've been stuck here all day.I'm having a difficult time with the Scrollbar component. I'm trying to have a scrollbar set up to navigate a text field or a MC of a text field. I managed to get it functioning within the desired frame, however when I jump to another frame, that very same content appears on the other frame, despite the fact that said frame did not have the scrollbar nor the content pasted within.
The bar seems to do what I want it to do save for the unwelcomed presence outside of the frame of choice. Here's the code I'm using. This is the keyframe code:
import boppreh.ui.Scrollbar
var scrollbar1:Scrollbar = new Scrollbar(boomboom, 500, true, false, 293, bar, slider, arrowUp, arrowDown)
addChild(scrollbar1)
scrollbar1.x = 50
scrollbar1.y = 50

Help Please!!! AS3 Platform game
I am creating a a platform game for one of my classes. I am not fimilar with Flash and I am having trouble with the coding. I keep getting this error message
TypeError: Error #1009: Cannot access a property or method of a null object reference.

at TheBallMan2_fla::MainTimeline/fl_ClickToGoToAndStopAtFrame_12()
TheBallMan2 is the name I have my project saved as.
My partner did all the coding but he doesn't really know what he is doing either. The character is supposed to move with the arrow keys which it did until we added the collision code. Here is our coding...which we got from following a tutorial online.

A litle help please... drawing app.
Hi all,
I'm trying to adapt a file I downloaded (legally) and I'm having some trouble as I'm still stuck in the days of AS2 and this has
been built in AS3. As you will see it's a drawing app that allows a few options for brush size, blur etc.,
What I'd like to do is to duplicate the brush_tool_mc with settings for full brush size and full blur to use as a spray can tool.
All my attempts so far have ended in disaster and multiple output errors ! : (
Any help / pointers / guidance much appreciated.
Best wishes
Tony

Sound not working in Flash Builder. Help please.
So, here's my situation. I keep trying to put an mp3 in Flash Builder to try and make sounds happen, but each time I do it only plays the beginning of it and stops midway through. My music is working at 44100 Hz with a 32 bit rate (tried changing it to 16, but Audition won't let me). Here's my code.
package
import flash.display.Sprite;
import flash.events.Event;
import flash.events.KeyboardEvent;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.ui.Keyboard;
[SWF(width = "550", height = "400",
backgroundColor = "#FFFFFF", frameRate = "60")]
public class SoundThing extends Sprite
[Embed(source="../sounds/try1.mp3")]
private var Try:Class;
private var _try:Sound = new Try();
private var _tryChannel:SoundChannel = new SoundChannel();
public function SoundThing()
stage.addEventListener
(KeyboardEvent.KEY_DOWN, keyDownHandler);
public function keyDownHandler(event:KeyboardEvent): void
if (event.keyCode == Keyboard.SPACE)
_tryChannel = _try.play();
I'm not sure what the issue is. Please help me. Thank you!I would say that either the OP needs two tabs somewhere to make his headings and line items align,Exactly what I was thinking. As this sample code illustrates, the b will not line up under Column#2. Perhpas OP needs to use a Formatter or the printf method instead.
StringBuffer sb = new StringBuffer();
sb.append("Column#1");
sb.append("\tColumn#2\n");
sb.append("a");
sb.append("\t");
sb.append("b");
System.out.println(sb); -
Hi guys , just joined!!!
I am a PHP developer and have 'forced' into some work with java.
Now I am a complete noob here and I have what I hope is a fairly straight forward request. I have a jar file that I have extracted so I can view all teh classess witihin and have found a class decompiler so I can actually see the code.
I need to edit one of the classes and then re-generate the .jar file.
What software do I need (just got the java studio creator and java studio enterprise...) and how exactly do I go about this process.
I have read a few pages abut this but still not confident so would really appreciate a hand holding exercise if anyone wuld be so kind.Hello! There seems to be alot wrong, so I don't know if I'll
get you up and running, but I'll try.
First of all you are stating "override function" for the
first 2 functions. This is only ok when you use it inside a class
(I assume you are coding on the timeline right?), so get rid of the
override.
Secondly I am not really sure what you are trying to do with
this part of your code:
addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler);
keyDownHandler {function event
(keyCode)==Keyboard.LEFT):void;{
gotoAndStop:(20);
addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler2);
keyDownHandler2(event )(keyCode==Keyboard.RIGHT);{
gotoAndStop:(30);
Are you trying to specify another 2 functions (you'll have a
naming conflict then as keyDownHandler and keyDownHandler2 are
already in use) or are you trying to call the above functions?
Third there are little flaws like gotoAndStop:(30); which
should be gotoAndStop(30); and some semicolons too much.
Hope that helps a little. -
I can't solve this for days already... When the hero object dies, the floorObject do not remove completely, such that one of them remains. And the hero object
disappears. Thanks for all the help.

if (Key.isDown(Key.RIGHT)) {
_x += speed;
this.gotoAndStop("right");
if (Key.isDown(Key.LEFT)) {
_x -= speed;
this.gotoAndStop("left");
