ActionScript 3.0 :: Keyboard Listener & Input Box?
Oct 11, 2011
I want to monitor each charachter in a text box when a user inputs, eg. there name. If they type John, I want an image to dislplay J . o . h. n under the text box. I cannot seem to figure out how to monitor each letter individually. I could only get it working if i use seperate input boxes, so a input box for j, o, h & n as an example.Could someone point me in the right direrection. Here is the code Im trying to use at the moment.
Code:
////////////////111111////////////////////
firstname.addEventListener(KeyboardEvent.KEY_DOWN, key_pressed);

Any way to change a keyboard listener I have set up, so that instead of reacting instantly when it hears a key_UP event, it waits to see if there's another KEY_UP within, say 50ms?

I was trying to make a tank game in which I can move the tanks, let them shoot each other, etc... I insist on creating external classes with Flash Pro cause I am used to OOP language like Java. I created a Tank class which represents all the tanks. Here is the code of this class:

The problem is that the action listener seems never get called when I press any keys. the trace() is not called. But I tried to add a mouse listener just to test and it worked. So I guess its the Keyboard event listener class's problem? Everyone I see on the web uses stage.addEventListener(KeyboardEvent.KEY_DOWN, move) approach.

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?
Code:
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
backgroundColor="#123456" creationComplete="init();">[code].............

I have a flash app that I would like to listen for a string of characters being typed on a keyboard. If a user typed in apple as an example that would either be correct or incorrect, and if they typed it in uppercase or lowercase or upper and lower it would still equate to true. Here is the tricky part, the string is not being typed into a textfield or anything like that, it must just be typed and after flash sees the correct keys pressed in the correct sequence it will fire a function.
I have seen this done before in a situation where a website had a background administration application, and when browsing the site you could just type admin, and a window would pop up asking for a username and password, so that is almost exactly what I want. Because of this I figured I would try to replicate the admin application first as it should be simpler
This is what I have thus far
stage.addEventListener(KeyboardEvent.KEY_DOWN, keysPressed);
var keyCatcher:Array=new Array(); var keyCatchNew:String;
function keysPressed(e:KeyboardEvent):void{
if(e.charCode==65 || e.charCode==68 || e.charCode==77 || e.charCode==73 || e.charCode==78 || e.charCode==97 || e.charCode==100 || e.charCode==109 || e.charCode==105 || e.charCode==110){
keyCatcher.push(String.fromCharCode(e.charCode));

I have a basic presentation which will have basic interactivity for the user. i.e. The user clicks on a play button, and the presentation plays, the user clicks on a back button, and the playhead steps back through the animation. I also want to provide keyboard shortcuts to do the same thing, so the user can also hit the spacebar to play the presentation, or press the left arrow key to step back, etc.
I've successfully gotten both the click interactivity and keyboard interactivity to work... but only separately, when I try to add them to the same file, it breaks. I also think I've figured out why. The problem seems to be that if I click a button that is only on the timeline for SOME of the frames, the KeyboardEvent listener no longer triggers.
I have a rewind button that will jump the playhead to the start of the presentation. However, from a use design standpoint, I really only want the rewind button visible/clickable if the user has advanced a bit into the presentation (i.e. frame 2 or beyond) because having the rewind button active on the first frame of the presentation can be confusing because it makes it appear to the user as though they can still rewind further, even though they've reached the beginning. I want to take a similar approach to a play button... as long as there are frames to play, the play button should be active; however, once you reach the end, the play button should dim down and not be clickable anymore, which serves as a visual cue to the user that they have reached the end of the presentation.
So, previously (in AS 2.0) this was not a problem. On the frame I wanted the rewind button to be "disabled", I would just turn the Button Symbol into a Graphic Symbol which would make it unclickable and remove any script, and then I would dim the Alpha of the Graphic. So, on frame 1, the rewind button would actually just be a transparent Graphic, and then once the playhead goes to Frame 2, it would be a Button symbol that could be clicked.
This technique apparently will break the new event model in AS3. If you look at the FLA I have attached (just change the extension), you can see that when you first "Test Movie"... any keyboard press outputs a trace statement that shows which key was pressed. However, if you hit the play button to play a little of the timeline, and then click the rewind button (instance name of rewind_btn) which jumps the playhead to frame 1 (where rewind_btn doesn't exist, because it's a Graphic now).
Now my Keyboard listener doesn't trigger!
I've even tried testing to see if the KeyboardEvent listener still exists by using the hasEventListener("keyUp"), and it returns as true, so the listener is there, it just doesn't trigger anymore
How would I go about solving this problem? Because I can see this being a huge issue in a more complicated project, because I could see scenarios where you only want certain buttons to exist on certain frames

I'm having what's probably a very basic problem, but I keep getting this error message: Error 1079: Label must be a simple identifier. I'm trying to have AS navigate through a panorama I made in photoshop and turned into a movieclip (panorama_mc). I want it to move from end to end (registration point is in the center) without going past the end of the photo on either side. I also want to make sure that when you get to the end, you can navigate back in the other direction.

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");

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);

I have two scenes in flash - when you go to scene 2 there is a eventListener attached to the stage to move a movieclip. When I test the movie the only way the keyboard listener seems to work is if I click on the stage first, then the object will move. Is there a solution to this. The code I am using is:

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;

I am new to Flash and this forum, so please excuse what will hopefully be a simple question.I am using Flash to build an interactive video kiosk for a museum that will be playing on a MacMini. it possible to create buttons or "scripts" that can be controlled with keystrokes? For example when you press "K" an embedded video will start playing. Or if you press "D", you could go back to the main menu? I am trying to make it so you can interact with flash via push-buttons, as opposed to moving a cursor over virtual buttons. Is this possible? would normally do this in DVD Studio Pro, but the sheer number of videos will not work in a single DVD project, so Flash is the only option I can think of. As a DVD it works great because I can use the arrow keys to navigate, and the enter key to choose a selection.

I have in a previous project published a game as a standalone app and run it full screen. It would allow users to put their info in for high scores.
Now i am working on another game that will be published as a standalone app. It will need to be full screen and have an entry form at the end for high scores. It does not seem to allow the keyboard to enter text in an input box. Is this true?
Note, this is not an swf played through a browser, but an actual .exe generated from Flash CS5. If this is true, is there a workaround. I need if full screen with keyboard input.

Since flash doesn't allow keyboard input while in fullscreen mode I'm wondering if there is a workaround to that?
I have a flash that is going to run fullscreen in a browser and needs different kinds of keyboard input. I have read something about AIR, but I don't fully understand it and would like another way if thats even possible.

can't figure out why the keyboard input isn't working. I got this warning, but I always get that warning and it always works. The warning says:Warning: 1090: Migration issue: The onKeyDown event handler is not triggered automatically by Flash Player at run time in ActionScript 3.0. You must first register this handler for the event using addEventListener ( 'keyDown', callback_handler).

I'm going true the AS Programming 3 manual and the [URL] example doesn't work. The authoring environment gets the focus. You can tel because you see the toolbar changing the selected tool as
you type the corresponding letter.
