ActionScript 3.0 :: Handling Keyboard Events In Classes?
Nov 18, 2009
I'm trying to handle movement of my Hero Class by adding event listeners in my constructor. I'm trying to move my Hero object.Inside my hero constructor, I have:
Code:
//Adding Event listeners
this.addEventListener(KeyboardEvent.KEY_UP, reportKeyUp);
this.addEventListener(KeyboardEvent.KEY_DOWN, reportKeyDown);
this.addEventListener(Event.ENTER_FRAME, EnterFrame);
And then I have functions for each of the events above. For some reason,the event listeners for key up and key down are never being triggered.

Is there any cross-platform-safe method for dealing with keyboard shortcuts in Flash? For example, on my Mac, pressing ctrl+f results in a KeyboardEvent where the keyCode is 6, but on Windows, the keyCode is 70.

I 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'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.

I am trying to use Javascript to intercept keyboard events, so I can do CMD-W for "close-window" and whatnot, inside a Flash application, so the Browser doesn't get to use them. Well, I am able to listen for ALT, CTRL, and CMD onKeyDown/onKeyPress events, but I am not able to listen to anything else...
Here is the code, in the index.html file from a Flex Project:
<script language="JavaScript" type="text/javascript">
document.onkeydown = function(event) {applicationKeyboardHandler(event)}
document.onkeypress = function(event) {applicationKeyboardHandler(event)}
function applicationKeyboardHandler(event) {
alert("Key Pressed")
} </script>
I would like to make it so it could listen to any key press, not just alt/ctrl/cmd.

In the attached code sample, keyboard events just don't work. The control never reaches handleKeyDown, no matter which key I press.

I'm working on a pause feature for my game and the only issue giving me trouble is how to pause/restart the sound effects and music that is being played in various classes.
I do understand how to record the position when stopping and then play from the new position. All code examples are based on a single sound being played at a time.
I have multiple channels to handle music and for various sound effect categories (so the volume may be controlled separately).
Currently, all of the channels are all in a single class but the sound effects they are assigned (.play commands) are executed within each class (Bullet, Enemy, Tank, etc...)
I'm sure other developers have experience with sound effects in various classes as well... so how did you handle pausing multiple channels and then restarting all of the same sounds that were playing previously?

I want to have a single event listener for multiple events and depending on the type of event i want to handle them separately.Something similar to Swiz framework see: 'Handling Multiple Events from a Single Method'.i have a piece of code like
var toolOptions:UIComponent=ToolOptions.createToolOptions(type);
if (options != null)
{[code]....
In above toolOptions is a mxml component which get dynamically created based on 'type'.Also which type of event should be dispatch the event from the component? eg: Event.SELECT. To be more precise the above is basically required for a toolbar.When user selects a tool,he is shown options for a tool and when he selects options,tool should apply them to object on the view.

I need to do something and I don't know if it's possible... in a proper way.
1 - I have an FULLSCREEN application that extends to two monitors in a Windows system.
2 - The graphic card is extending the single desktop to the two monitors, so the fullscreen fits everything correctly.
3 - Only one monitor is interactivity-enabled, with an interactive touch-sensitive foil on it, which works great.
4 - The second monitor is interactivity-disabled, it just displays stuff depending on what happens on the first monitor.
The Problem: The interactive foil on the interactivity-enabled monitor responds as if it is the *whole monitor*. But it only covers one monitor!! The *whole monitor*, are the two screens put together. I obviously can't cut the interactive foil in 2, and then stretch the two parts to fill a monitor each... So if one touches beyond 50% of the foil's width, the touch event will actually occur in the second monitor!
A fact for the solution is - if all Mouse Events occur with mouseX divided by 2, everything will work fine! How to make all Mouse Events's mouseX be divided by 2? Is there a way to do that in the core of the actionscript MouseEvents handling?

I'm trying to write a simple counter. UP or Space increments a number and DOWN decrements. It's just one big number in the middle of the screen. A bell rings on an increment and I have added code to go full screen on mouse click.
Test mode works fine ( except for full screen of course).
Seems to work fine on the local machine using Safari 3.2.3
However if I try to run it locally using firefox it does not work.I need it to run on a laptop but it does not always acknowledge the keyboard events and while in full screen it never responds to the keyboard events.Laptop is running Safari 3.2.1

I was looking at this game called "Tsunami Fighter" (if you google it, it'll be the first thing that pops up�I can't post links sadly) which is a keyboard mashing game. Basically you have to mash a certain keyboard button as fast as possible to stop the rage bar from reaching the top. I tried some things that I thought would work,
How would I script the keyboard mashing part of this game (The part where you have to keep a greater keyboardclicks/second than the rising bar You'll know what im talking about if you play the game. I'm not really concerned at the score or the graphics just the keyboard event thing.

I created an E-learning project for a customer that has pages that require the user to make keyboard entries. When the user enters a specific letter, the page progresses. The pages work as expected until the customer places the project in a 'wrapper' that controls the navigation. When this is done, the user can make the keyboard entries, but now the page will not progress to the next section. It seems that the wrapper is stopping the system from detecting that the specific letter is pressed.

why the swf does not catch any keyboard events? When i Ctrl+Enter my .fla there is a message appearing that says: "Your content will not stream. Runtime Shared Library (RSL) preloading will require all of your content to download before the first frame will play. To prevent this you can change the Runtime Shared Library Library Settings in the Advanced ActionScript 3.0 Settings dialog which can be raised from the Public Settings dialog. The Runtime Shared Libraries being preloaded are: textLayout_1.0..........."

I am adding a key listener to my AIR application like so:
<mx:WindowedApplication
xmlns:mx="http://www.adobe.com/2006/mxml"
keyDown="onKeyDown(event)">
Yet only sometimes when I press keys does it actually invoke. I have no clue why, I thought maybe something else has focus. Well I cannot add key listeners to NativeWindow or NativeApplication, and I would assume if it is on the WindowedApplication which is the root element, that as long as my application has focus the key presses should invoke the listener.

I have a key.addlistener setup to listen to key events.What I want to be able to do is to dispatch key events by for example a mouse click or just on load. I've tried a lot of possible solutions such as dispatchEvent with type as "onKeyDown" and "keyDown" etc.... but key listener simply do not treat it as a keyboard event.
Code: Select allvar eventObj = new Object();
eventObj.type = "keyDown";
eventObj.code = 13;
eventObj.ascii = 'e';
dispatchEvent(eventObj);

Is there way to navigate to various buttons on a stage using only the keyboard? I have several movies (complete with cover art) on my Flash stage. I want to convert them into buttons so that anytime a user navigates to that button and presses enter, it will take them to a new frame (where I will have information about that particular movie). I know how to do this with Mouse clicks. But, this application requires users to use arrow keys in order to navigate and not the mouse.

I want my animation to STOP when I press SPACE, and then PLAY when I press SHIFT. This needs to be in AS3. The only catch is that my whole animation is composed of 5 Scenes. Would this be a problem? Also, I'm confused as to where I should add the code. I have it in a class and it still doesnt work. I tried putting it on the 1st frame on Scene 1.
