I'm trying to detect keyboard input and if the arrow keys are pressed, set the players next move to whatever was pressed. I'm listening for keyboard input using:
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown);
This is the function that gets called:
public function keyDown(event:KeyboardEvent):void

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 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).

this.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);

When game starts, the car runs automatically. Then we click the SPACE button, movement of car stops. And the door of structure near car is available to CLICK.
But in coding I got this error code:
TypeError: Error #2007: Parameter listener must be non-null.

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
how to get the charCode from the character but I cant seem to find out how to get the character from the charcode.
Basically I am I am listening for the KeyDown event on a TextInput.
I prevent the char from being typed via event.preventDefault();
Later I need to add the text-char to the TextInput.
I can get the charCode via event.charCode so if I can turn that into a string I can save it for later user.
Why I need it
Basically I am making a TextInput, that that I can set to display default text in it. When A user types into it, I want to remove the default text first then add the user typed text.
Currently I am either removing it all, or ending up with both.
How do you replace text based on a charcode?
View 1 Repliesprivate function pressedLetter(event:KeyboardEvent):void
{
pressedKeyLabel.text = String.fromCharCode(event.charCode);
}
According to code below, the letters such : "ı, ğ" could not be displayed at pressedKeyLabel, it shows different things. how can i display this letters correct ?
i'm looking for a way to capture key press based on the character pressed. using KeyboardEvent.KEY_DOWN has some problems: i can use String.fromCharCode works for letters only (and have to do capitalization manually using shiftKey boolean) but it doesn't work for other characters. the keycode for - (hyphen) is the same as for _ (underscore), for example, and fromCharCode returns the 1/2 (half) symbol.
View 1 RepliesIs there an easy way to convert keyCode to charCode?
Either this or a way to get the name of a key via it's keyCode and not it's charCode (I've made all of my movie use keyCodes so far, and I really don't want to have to convert it just to get the name of the key).I know there is a String.fromCharCode but this isn't what I need, I need one from keyCode.
I thought all keyboards were alike other than maybe special Chinese and Japanese ones. I was guessing that, other than adding a few extra letters (such as Sweden's the keyboards would be identical... WRONG. find it extremely annoying typing since when I reach for a ", I get an when I want a closed curly bracket, I get ^. Swedish keyboards are not a programmer's best friend. It is quite frustrating, but that is another subject, and quite off topic.o doubt, since the key locations vary so drastically in some areas,How are "keyCode" and "charCode" values different if captured from other keyboards?How smart is Flash, and how much does the developer need to compensate for this?Is there any way to detect what type of keyboard the user is currently using?

I am creating a game where you have to use the up and down buttons on the keyboard to avoid movie clips. For some reason it won't register when i press the keys down. Here is my code:
[Code]...
I'd like to arrange things so that I have a chain of keyboard event handlers in my flex application, all of whom are queried when key down events occur. Basically, when a visual component is on screen, it is a candidate for handling a key press event. Something like this (clearly this is pseudocode):
<application handles_keys="F5, F6">
<tabGroup>
<tab1 handles_keys="pgup, pgdn">
<control handles_keys="0,1,2,3,4,5,6,7,8,9" />
[code]...
I have a class written that will respond to the key events the way I want it to, so how do I register one or more instances of this class to have the results I want? Also, note that there are some situations where this class should receive events that would ordinarily be handled by a UI component. The TAB key is the main example; I have a few cases where I want my key down event handler to fire even when the focus is on a text field.
Tracing the keyCode for the 'a' key (65) only works once for KEY_DOWN events and sometimes KEY_UP behaves in the same way, making development a pain when trying to do things quickly.
Clicking on the stage makes it start working, but why is it just the 'a' key that is affected?
This is on a new MBP running OSX 10.6.5, Flash version MAC 10,1,102,64

The issue can be reproduced every time with this code:
ActionScript Code:
import flash.events.KeyboardEvent;
stage.addEventListener (KeyboardEvent.KEY_DOWN, keyDownHandler);

I have a button on the stage called enterCostBtn that when it is pressed it executes the code inside the calculateCost function. What I want to do is to be able to use the ENTER key on my keyboard to trigger that function. In other words I would like to be able to use the ENTER key or click directly on the enterCostBtn to trigger this function.
Code:
enterCostBtn.addEventListener(MouseEvent.CLICK,calculateCost,false,0,true);
function calculateCost(event:MouseEvent):void {
var material:Number=Number(Material_txt.text);
var labor:Number=Number(Labor_txt.text);

I'm an artist, not a developer, but I work with various media. I am so~so with AS3 and JS and a total noob with PHP and databases.Anyway, I am writing a Class based on keyboard events and I am finding that if the keys are hit too fast the triggered events don't complete.I'll explain further:I have a picture broken into parts (a red background here, a blue stroke there, and so on). Each one of these elements is a Library Object, and they are all set to alpha=0, and each one in turn, is tied to a key on the keyboard. When the key is struck, the picture element goes to alpha=1, plays a sound, and starts tweening back towards alpha=0.
Code:
public class TypedImageV4 extends MovieClip {
public function TypedImageV4() {

I have been reading for about an hour online with no solution, if you are typing in a text field, you seem to not be able to read if the "enter" key is pressed, exmaple attached.
View 8 RepliesI'm still a beginner in programming ActionScript 3.0,
I had a problem with KeyboardEvent in ActionScript 3.0,
I created a simple shooting game, the game has 2 Frame,
1. Title Game (Frame 1)
2. Game Playing (Frame 2)
The problem is in Frame 1 when Button is clicked playinggame
then switched Frame to Frame 2 where the game takes place where the user can move the aircraft by using the keyboard, (Left Arrow, Up Arrow, Right Arrow & Down Arrow).
But when a keyboard button is pressed, KeyboardEvent not react at all, and aircraft can not be controlled.
Even more bizarre when the stage at the click KeyboardEvent can react and aircraft can be controlled.
The question is how to keep the button is clicked playinggame in Frame and the Frame 2, the aircraft can still be controlled using the keyboard

I looked around but I didn't find any event sent by the TextField whe the keyboard cursor enters or leaves the field ?
View 5 RepliesMost flash games and interactive animations that use keyboard events are made to respond in different ways to different keys.I am working on games for toddlers, who basically just bang on the keyboard indiscriminately. The trouble I'm having is setting up keyboard eventlisteners (key_up) that each perform different function.We're talking games like: when key pressed, ducky dances; when key pressed, doggy dances; when key is pressed, ducky and doggy go to sleep. I've attempted removing the listener before adding the next one:
stage.addEventListener(KeyboardEvent.KEY_UP, doSomething);
function doSomething(evt:KeyboardEvent):void
{make it do something;

I am working on a game project and i have a question about movie clip movement using keyboard event. Basically I have a character on screen and it can move on the x axis using the left and right buttons. I am making my character move by changing the x value of the character movieclip but I find very it laggy and not smooth and if I am going point by point then it's too slow. Whats the best way to make the character move so that the transition will be smooth.

I'm trying to get familiar with the whole keyboard event detection thing.Here's my sample code.
<fx:Script>

import flash.events.KeyboardEvent;

now I'm trying to make the keyboard events to stop repeating.
My idea was to have a true and false condition for when the key is pressed so that it wont repeat if the key is down already.
//Mouse Event Over
keyCButton.addEventListener(MouseEvent.MOUSE_OVER, function(){gotoAndStop(2)});
//Variable
[Code].....
doing this makes the key loop over and over without a keyboard event I think i need to add a "&& keyDown..." to "if (this.soundplayed==true)" but i dont know how to do it without getting errors
here is the keyboard player i'm trying to fix [URL]
I have a textArea and would like to prevent the default behavior for certain keys such as the enter key from being run upon user input. However, KeyboardEvent is not cancelleable so preventDefault does not work.
