IDE :: Getting Responsive Keyboard Movement - Multiple Keys Pressed
Feb 16, 2010
Im having a problem getting responsive keyboard movement. I have a key_up listener which fails to trigger when 3 keys are down. E.g. Imagine up and right keys are being pressed to move up + right. The user wants to change to moving up + left. The user presses the left key before lifting thg right key. I have a key_up listener to detect when a key is no longer being pressed. However in this scenario it fails to trigger when 3 keys are pressed. Even in this online example, there is the same problem, look how unresponsive it is when chaging from up right to up left really quickly. [URL]

I want this code to move my map i.e map_mc when the keyboard keys are pressed. When I add it to the map_mc, I see no effect what do u think I am messing with.
Code:
on (keyPress "<Left>") {
currentX = this._x;
this._x = currentX - 2;
} on (keyPress "<Right>") {
currentX = this._x;
this._x = currentX + 2;
} on (keyPress "<Up>") {
currentY = this._y;
this._y = currentY - 2;
} on (keyPress "<Down>") {
currentY = this._y;
this._y = currentY + 2; }

I have it like this so far:
ActionScript Code:
stage.addEventListener(KeyboardEvent.KEY_DOWN, KeyPressed);
stage.addEventListener(KeyboardEvent.KEY_UP, KeyReleased);
public function KeyPressed(event:KeyboardEvent):void
[Code]....
and so far it works good, except when I press shift. If I'm holding the left or right arrow key and then I press shift, the object stops moving and doesn't do anything. However, if I release the arrow key and THEN press and hold shift, it works perfectly. How can I make it so that I can press shift while I'm holding the arrow key and still have it work?

I am struggling a bit with keys on the keyboards controlling a movieclip to happen.Ive got a person moving when pressing right and left, and a movieclip with three frames: First frame is a movieclip with the person standing still, looking bored. The second frame is the person moving right, and the third frame is the person moving left.This is the code that Ive inserted into the persons actions on scene1:
if (Key.isDown(Key.RIGHT)) {_x += speed;this.gotoAndStop(2);_xscale = +scale;}
if (Key.isDown(Key.LEFT)) {_x -= speed;this.gotoAndStop(3);_xscale = -scale;}
this code works alright accept that when the keys are not pressed it doesnt stand still, the legs are still moving, so I tried to include this code aswell:
if (!Key.isDown(KEY.RIGHT)) [code]....this makes the person standing still when not pressed but not moving the legs when turning right and left.

How do you detect when to keys are pressed together. For example, if I press W and E together, I want something to happen. How do I do that?

I am doing a Flash game for school with parallax scrolling. Though I am going a much simpler way of the art, I am having one major error. My error is that when I stop pressing the Up Arrow Key, my ship does not move. All that my ship does, is sit there doing nothing, except for the following; exhausting fuel and showing the flame animation. Detecting if the Up Arrow Key (evt.keyCode == 38), I have tried both code below:
ActionScript Code:
!evt.keyCode == 38
and
ActionScript Code:
evt.keyCode != 38

Cannot Detect All Key pressed onKeyDown
Here is the code I used:
Code:
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
trace("DOWN -> Code: " + Key.getCode() + " ACSII: " + Key.getAscii() + "
[Code]....
It is an usual code to listen the key presed on the keyboard. For some reason, I cannot detect any letter-key exept letters "w", "x", "d" and "J". I tested it on a different computer and results are the same. It is driving me crazy. I am not sure what is the problem.

I'm developing a little game. I use the following code to detect the keys pressed by the player:
[Code]...
Basically the shootKey will be hold down by the player almost all the time. And the changeColorKey will be pressed very often but not hold down. While testing I noted that holding the shootKey and the right arrow down, the onKeyUp events for the changeColorKey don't get fired. Holding the up or down arrow key instead of the right arrow has the same effect. If I hold the left arrow key the events get fired. Why does it occour? Is there something wrong with my code?

I've followed the thread there: [URL]
I understand that this class allow the script to detect when keys are pressed in combination.
But what is exactly the implementation when a key is used both in single and combination states. Let's say that you've the "q" key used alone and "shift-q"...how would one proceed to achieve this detection?

Create a listener that will wait for a combo of keys pressed to launch a command? Something like if they type "admin" it will trigger a function.

I have this code on a frame in the main timeline:
ActionScript Code:
addEventListener(MouseEvent.MOUSE_DOWN,startSquare);
stage.addEventListener(KeyboardEvent.KEY_DOWN,addPoint);

When I test it, it seems to ignore most keys, but notices others. I went through the alphabet, and it only responded to dguw&x

2) It is working slowly, when i loaded its compiled swf with another swf but working fine when played individually, i hv specified the different stage.framerate for both swf in their corresponding class.

I have a word; let's say it is "GAME". How can I check if I pressed the "G" on my keyboard?
I just can't seem to figger it out.
PS. If I want to show text on the screen, do I really have to make a new textField, or can I use something like 'echo' in PHP?

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.

I used to use AS 2.0 but I've finally made the switch to 3.0. I am majoring in CS so I am familiar with basic/intermediate concepts, but I am very unfamiliar with 3.0. I have a movieclip controlled by arrow keys, however the movement is still slightly choppy. Everything is uploaded below, the code I note here is the code for movement located within the .as file.
Code:
package {
import flash.display.MovieClip;
import flash.display.Stage;
import flash.events.KeyboardEvent;
import flash.events.Event;

I'm using a keyboard event to detect when a key is pressed. This is what it looks like:
Code:
private function keyPressed(event:KeyboardEvent)
{
switch(event.keyCode)
{
case Keyboard.CONTROL:
ctrlHandle=true;
[Code]...
It's worked up until now. I know that all the keys except the last one work because they carry out their function and the trace on DOWN works. However, for the last one, I've tried W and ALTERNATE (and got errors) and ESCAPE and TAB (both not doing anything, not even returning the trace).
