ActionScript 3.0 :: KEY_UP Not Recognizing ?
Mar 7, 2011
I have a typing game and I want to be able to detect period and commas, however unless you are holding down another key (any other key), the period and comma keys do not trigger KeyboardEvent.KEY_UP. I found that sometimes they would work when focus was set to the document class. After hours of debugging my game trying to figure it out, I decided to create a new project to JUST test this problem. Here's the absolute barbones example:
package
{
import flash.display.MovieClip;[code]..............
If you run this, it should automatically set focus to the document class. At this point, the period and the comma do not work. Now click the stage and you will find that the comma and period do not work UNLESS you hold down another key (for example hold down the m key and then press the comma key). Also at this time, focus is set to null.Now click the textfield, and the comma and the period work again.

I am trying to capture Ctrl+C. I have noticed that many times, there is no KEY_UP event for C key. I believe it happens in cases KEY_UP event for C key should be thrown just before or after KEY_UP event for Ctrlkey.
Why does this happen? How can I catch the KEY_UP for C key?

The problem is that I've done a lot of work in my game, and there's too much code bound to shift and control keys. For example you need to hold shift key to select multiple soldiers or control key to shoot or sometimes pause the game or even call a map, a lot of stuff in GUI depends on those keys as well. Both KEY_UP and KEY_DOWN are added to the stage object. But, time after time, there happens a very annoying thing, KEY_UP event just doesn't fire for shift or control (in most cases it does, but not always). That is, I press shift, start selecting soldiers, then release shift but Flash Player keeps thinking it's still pressed, so I can still select multiple soldiers, which is not good.
I found the exact same problem here: [URL]

I'm using very basic code to move an object around the stage using keys on the keyboard (W,A,S,D). However, I have noticed at times when the CPU hiccups, flash does not register that a key was released and in turn my object keeps moving in a direction without any keys pressed. The only way to stop the object from moving is to press the key corresponding to the direction the object is moving.

I'm trying to make as3 application which uses custom mouse pointer while pressing spacebar on my keyboard. Everything works fine when I don't move my mouse but when I do the KEY_UP event is dispatched to my listener almost immediately (and this is while I'm still pressing my key down). Below is simple main class which used to test this behaviour:

I have discovered a bug with KeyboardEvent.KEY_UP keyLocation values for the shift keys. how to reproduce this:
1.when no other keys are down the value for left shift is 1 and for right shift is 2 for KeyboardEvent.KEY_DOWN and KeyboardEvent.KEY_UP
2. when you have pressed shift and then press another key - when releasing shift the value for left and right become 0.
There is absolutely no reason why these values should report anything other then what they initially reported on key down as each key fires its own event with details for each , regardless of any key combinations. Im using cs5.5 windows 7 basic.

I´m trying to catch KEY_UP event if I press ENTER, without clicking on stage.
I´ve already disabled keyboard shorcuts for flash player, and added stage.focus = stage.
Not succeeding.
It only works if I click on stage.
It seems that for the other keys the KEY_UP works.

Try the following code:
myListener = new Object();
myListener.onKeyUp = function() {
if (Key.isDown(Key.CONTROL) && Key.getCode() == 67) {
[Code]....
hold Ctrl key and start pressing C. From some point you will notice that there is no KEY_UP event for the C key (there will also be no event for A,X,R,V and maybe more). For most of the button the KEY_UP event will still be dispatched.

I'm programming a Flash-based site designed by the client. The trouble is the SWF dimensions are small within the HTML page, and the thumbs show the larger images on roll over. The large images are meant to disappear on mouseout, but it's easy to move the cursor too quickly for the mouseout to be recognized -- so the image gets stuck on screen.

Code:
SetNextProject = function () {
i++;
ProjectPreloadB(currentArray[i]);
[code]....
The point of this code is to make button mc_arrowF go away when the end of the array is reached. Its BASICALLY working, however when i load, say currentArray[18], the end of the array, the button doesn't disappear until i press it again. Basically, the button doesnt disappear until currentArray[19]... even though currentArray.length=18.

So I have a Clef class:
package Clefs
{
import flash.display.MovieClip;
import flash.ui.Keyboard
[Code]....
Yeah, I have no idea why it thinks getNoteCode isn't a function. For the record, I'm coming from AS2. I don't like that I can't give linkage instance names to objects in my root .fla - that was handy.

I've built a flash application on which I've created a webservice client to consume a dotnet service. when the full domain ex: www.yourdomain.com is used to load the site (primarily html and asp.net code with just a flash client) everything is fine. If I load the website using just... yourdomain (no www) then the flash interface activates but never returns a response. I've tried loading a cross domain policy file to see if that could be the issue to no avail. So far no www flash bugs are turning up as a common issue on Google, maybe I'm not using the right key words?

I'm working with Flash Builder 4.6 as an IDE and Flash CS5.5 to create library items. The problem is - when I put an instance of a library item on the stage or inside of another item, Flash Builder fails to detect the instance name that was declared in Flash CS. This doesn't prevent the code from compiling just fine though.
I understand that the IDE only sees the fields that I have declared directly in the .as file, but it really hinders me that I the IDE goes crazy when I do this.
Is there any way to circumvent this - other than dynamically creating and placing the instances?

I need a way of recognizing what weapon is currently being held.The way the weapons works is it is a movie clip, with multiple frames, each with a different weapon, and each weapon has a different minimum/maximum damage they can do. How can i make a code that recognizes which frame the weapon movie clip is on?

I have recently been given an Actionscript framework that was developed in Flash CS3 or CS4 and it compiles fine in Flash CS3 and Flash CS4. I am now working with Flash CS5 and do not have CS3 or CS4 installed. When i compile the files in Flash CS5 it throws an error and does not properly compile. It appears that Flash is not recognizing one of the AS classes in one of the directories within the framework. Has anyone experienced this with Flash CS5. These files worked fine in Flash CS3 and CS4 but I can't seem to figure it out for CS5; is there a setting or config option I am missing?

My program beings with a frame with a "play" button on it. Once he "play" button is clicked the user is taken to the second frame to play a game. Control for the game is done via key presses. The control works well; I'm able to move the sprites and so forth. However, my problem is after the user clicks "play" and is taken to the second frame the game will not recognize key presses until the user has clicked the applet again. How do I get the game to recognize key presses automatically after the user has clicked "play"?
Here is the code I use in the second frame to listen for key presses:

why "hitTestPoint(character.x, character,y, true)" would be hit testing off the origin point in the center of the character, and not the whole shape??
This is my code from my document class. There's a custom splat class in there, but don't worry about that. This code is inside 2(1 nested) for loops.
function hitTestBalls(e:Event) {
for (var i = ballArray.length - 1; i >= 0; i--) {
for (var m = MonsterArray.length - 1; m >= 0; m--) {

Something is corrupt with my Flash Professional CS5 Actionscript Auto format: Comments within a block, such as ' // ' or block comments ' /* ... */ ' are tripping up the Auto Formattor, which returns this error: ' Error with autoformat near line: }'. Comments before package block don't cause an error. When I remove comments within package block, Auto format works correctly.

I have an .as package that I have attached to a simple .fla with a List component and named it list. I have done this in an earlier document that I built using a tutorial and it worked then. Now I am getting an error:1120: Access of undefined property list.This is something that I've seen a thousand times when I forget to give something an instance name, but this time I have not forgotten. I've double and triple checked. The .fla file is just a document with a list component on it. It will be getting its data from a html page via javascript. Here is my package:

I am trying to develeop a Graph Structure with drag and drop features in Flex. I have to connect various components/children on the canvas. Once i drag n drop the components on the canvas, i am using SystemManager event handlers to draw connectors between the components. But, as i click on one component and drag the mouse, the line is drawn on the canvas as long as my mouse stays only on the canvas. If the mouse moves over a component/child(that has been dragged and dropped onto the canvas), the line is drawn to the origin of the canvas from the first clicked component. How shud i recognize the component when i move my mouse over the component? I want the line to be drawn connecting the components once my mouseup event is called.

I have this class:

I have something like this as a part of my code
Code:
var gen:particle;
var a:int = 0;
var b:int = 1;
[Code]....
As you can see i am creating instances of particle and adding them stage and then giving them instance names.
Now in the empty event handler function I want to access these instances of particle I created by their instance names and change their rotationX values.
how do I call these instance names in the for loop in the second function. I can generate the string pretty easily, but how do I get flash to recognize these strings as instance names?

I have a main swf file, Main.swf, which has an associated .as file, mainClassCode.as[which actually does nothing, it is not being used]. Main.swf, loads an external swf,ContentHolder.swf, which has a base class contentHolderClass.as. Now all the stuff that happens within ContentHolder.swf, is within the contentHolderClass.as. There is nothing on the stage within ContentHolder.swf, and everything is being done by the base class. Now when I test the ContentHolder.swf on its own, everything runs fine. But the moment I load it through Main.swf, I get a million errors, stating that none of the movieclips in the ContentHolder.swf library are being recognized by contentHolderClass.as..Why could this be happening??? I have imported contentHolderClass within Main.swf [in frame 1], and I after I addChild(ContentHolder loaded swf)
