ActionScript 3.0 :: Detecting Multiple Keys Pressed Without Bugs?

Nov 1, 2010

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?

ActionScript 1/2 :: Keys Pressed Or Not Pressed?

Dec 6, 2010

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.

ActionScript 3.0 :: How To Detect That No Keys Pressed

Jan 9, 2012

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

ActionScript 2.0 :: Cannot Detect All Keys Pressed OnKeyDown

Aug 12, 2009

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.

Actionscript 3 :: How Many Pressed Keys Flash Can Detect

Dec 1, 2009

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?

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]

ActionScript 2.0 :: Make A Box That Fades In When Pressed On The Button And Fade Out When Pressed For The Second Time?

I have a function on root:

This causes a mc to fade in and out on rollover/rollout. But what I wanna make is a box that fades in when pressed on the button and fade out when pressed for the second time. But if I say

on (press){
_root.fade = true;
}

the mc fades in, but I cant do another on (press) to fade out. Is this too confusing?

ActionScript 3.0 :: Reading All The Keys?

May 28, 2009

using the authoring tool to test,I find I can only read certain keys via:stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown);
 
But when I test in a browser, I can indeed read all the keys. So the IDE must be intercepting certain keypresses. E.g., I can read w and d but not e.

How can I read all keys? Testing in a browser all the time is a bit inconvenient
