When I am pressing a key nothing happens. I have 2 AS files and a Ship object in the library.
1st is Engine.
Code:
package {
import flash.display.MovieClip;
public class Engine extends MovieClip {
private var ourShip:Ship=new Ship();
public function Engine() {
addChild(ourShip);
[Code] .....
I have a ship on stage but I can't move the ship with keyboard
Code:
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard;
[Code]...
I'm making a top-down shooter game.I have keyboard input that moves the ship around and fires a laser. everything works perfect except that when the ship moves diagonal up left, or diagonal down right, the laser can't fire at the same time. It will work in any other direction, including the other diagonals.here is my code:
[AS]
function captureKeys() {
if (Key.isDown(Key.RIGHT) && ship.x < 355 ) {
ship.x+=ship.right[code].....
I'm debating two approaches to a pretty typical problem: Knowing when an event occurs or responding to it immediately if it already has occurred. In approach one, a user of MyLoader1 adds an event listener which will be fired immediately if the loader is already complete.
class MyLoader1 extends EventDispatcher {
private var _isComplete:Boolean = false;
public override function addEventListener(type:String, listener:Function, useCapture:Boolean=false, priority:int=0, useWeakReference:Boolean=false):void {
super.addEventListener(type, listener, useCapture, priority, useWeakReference);
[Code] .....
What advantages/disadvantages are there to each approach? Is there a design pattern out there that I could/should be using for this situation? I'm leaning towards the first because it requires less knowledge of the Loader class and less code to leverage it. It could potentially create unwanted side effects when there are multiple listeners though, because the event will fire once for each time a listener is added. The second method is understandable and easier to debug, but requires more up front work and seems to break encapsulation of the Loader.
I'm creating a container as a MovieClip and adding a mousewheel handler, then adding items to it like so:
Code:
container = new MovieClip();
addChild( container );

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).
private function onInit():void{
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:

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
I'm assuming the answer to my question is "no" but figure it's worth asking just in caseI'm mostly an AS3 coder, but I need to work on library assets quite often to set classnames on assets so they can be instantiated through code. This usually involves hunting through the Library for the asset I need, then giving it a new name, clicking the tiny little "info" icon at the bottom of the window to bring up the Properties panel for the library item, and assigning a class name etc.
My problem is bringing up the Properties panel is not as quick and simple as it should be. That "info" icon really is tiny, and right-clicking the item in the library and scrolling through it to get to the "Properties" item is fiddly and error prone.What I really want is a keyboard shortcut. There doesn't seem to be one, and I can't assign one in the otherwise excellent Keyboard Shortcuts... menu item since Library commands are not listed there. It is not even a menu item so I can't even trigger it with applescript.
I have several stage event handlers to enable mouseovers over several dynamically generated moviecilps on the stage that then change their alpha to indicate the mouse is over that particular mc... fairly trivial (mcOver handler). Additionally, I also want to know what MC is clicked, so I update a public variable (public var activemc:Number) with the ID of the dynamic movieclip when the mouse is over it (using a hitTest to check, which is why the EventListener is added to stage and not to the MC), which is checked in the mcClicked handler:This is in the constructor:
//stage.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing);
//stage.addEventListener(MouseEvent.MOUSE_UP, stopDrawing);
stage.addEventListener(MouseEvent.MOUSE_MOVE, mcOver);[code]....
However, the mouseover behaviour (alpha 0 when over, alpha 1 when out) stops working as soon as I click on any movieclip on the stage, and the mcClicked ID checking (below) stops working completely. I don't know if this is to do with focus:
private function mcClicked(event:MouseEvent):void {
myTextField.text = String(activemc); // activemc is a public var:Number with the movieclip //ID
}
I then tried adding the event handler for the stage mouse_move again and this gets the mouseover working again but only for 1 more click, after which it stops again:
private function mcClicked(event:MouseEvent):void {
myTextField.text = String(activemc); // activemc is a public var:Number with the movieclip //ID
stage.addEventListener(MouseEvent.MOUSE_MOVE, mcOver);
Is there a keyboard shortcut to duplicate items in the Library. I'm having to right-click and select Duplicate right now.

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.
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
[code]....
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 trying to write a keyboard event listener so that when I press a specific key it controls the time line. Below is working code for when I press "enter". How would I make it work if I pressed "Q"?

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.
View 3 RepliesI want the user of my game to be able to press the Space bar and be taken to a new scene. I know how to do this with a button, but I can't figure out the code to use for a Keyboard event.
