AS3 :: Flash - Check Keyboard State Without Using KeyboardEvent?
Apr 10, 2010
Is it possible to check for pressed keys without using the KeyboardEvent?
I have an ENTER_FRAME event setup called enterFrameHandler and I want to check within the function enterFrameHandler if any keys are pressed.
normally when using a KeyboardEvent I could check for keys easily using a switch that checks the KeyCode of the event, but in an ENTER_FRAME event this isn't possible for me.
Is there any other way of checking the keyboard's state within the ENTER_FRAME event?
UPDATE:
I found this AS2 script:
onClipEvent (enterFrame) {
if (Key.isDown(Key.LEFT)) {
_x -= power;
[Code]....
This seems to be doing what I want, but it's in AS2, does anyone know how to 'translate' this into AS3?
I have been at this for 5 hours and I'm about to pull all my hair out.I have a seemingly very simple problem that I can NOT find any reason for why it's happening.I built a simple flash doc that has three distinct pieces in it (2 frames):
1) A FLVplayback component on frame 1 - (working)
2) An AS listener that checks for end of Video and progresses to 2nd frame - (working)
3) a cookie script that checks to see if the video has been played and if it has skips frame 1 and goes to frame 2 (also working)
The video successfully plays the first time and moves to the 2nd frame. But, when the document is reloaded it checks the cookie (finds it) skips the 1st frame, moves to the 2nd BUT it does NOT display ANY of the elements in the 2nd frame. NOTHING!! There is a simple graphic and button that allows the users to replay the video (by simply clearing the cookie and going back to Frame 1) but they do not show up. (However, they DO show up if the video plays first and moves to frame 2 via the listener, just not via the cookie).I have placed traces in each frame to show if it is indeed arriving on frame 2. It is, but NOTHING shows.I have rebuilt the FLA step by step testing each time and have found that it works perfectly, right up until the FLV Component is dropped in. Then it moves to the 2nd frame and shows NONE of the 2nd frame elements. URl...
Any best way to script several MCs (acting as buttons) so that on release(), the alphas on the others tween to 20. When you go to click one of the dimmed button, its alpha should tween back to 100 and the previous one that had the full alpha should now fade to 20. Logically, I know I need to somehow implement a variable to check the state of the MC and an if statement to script the actual alpha tweens but I'm confused as how to actually implement it. Where to put it etc.
I am using the mousewheel mouse event and keyboard keys to perform certain actions. But how can i check when the user has stopped using either the mouseWheel or keyboard?
When using a notebook and I have remarked that I cannot enter numerical character with shift + a letter to enter number.Is this a bug in flash ? How to circumvent this ?
i curious how to access state in flex "Current State" from flash movie clip??..so far i make movie clip in flash and it has button inside with name " button" and i put this flash file into flex in "state 1" flex application..i want to make event handler for "button" that trigger changing state from "state 1" to "state 2" in flex application..and in flex application i do not write anything because i have no idea how to deal with this stuff..
I have already stumbled across two games (I mean... um... work related Flash stuff, yes boss, I'm working) which get "choppy" when you hold down the key to move (though it should apply to all keys)You know when you are typing in word, if you hold down one key, first you get one letter printed, and a second later it writes that letter really fast multiple times until you release? I believe that is what is happening that makes those games choppy. This is likely because the "KEY_DOWN" event gets dispatched very many times for the same reasons.
Now, either both those games were crappy enough so they forgot to test for this issue, or it's a Linux specific issue. I need you (yes you) to double check (stating your operating system and browser) if you get the same results.If you hold down the key to go left, (or right, doesn't matter) first you go left smoothly, and then after a second it starts "chopping" and resetting the movieclip's frame to the first walk frame.
I'm new to ActionScript development and am using the FlashDevelop IDE. I've been playing around with some really simplistic things and have come across a problem I can't seem to solve.My application compiles and runs, and a function that watches click events fires perfectly and I can see the event in the console when I pass it to trace(), yet the same code watching for KeyboardEvent fails to fire at all.Here's my code:
Ive been using the 'event' parameter for my KeyboardEvents and MouseEvents in a recent project ive been working on for my course (VERY BASIC).Im not entirely sure on what the 'e' part of e:KeyboardEvent actually does, and ive been asked to find out what information the parameter 'e' can actually access when using it.
EDIT: If A method takes the parameter (e:KeyboardEvent). what information could we access through the use of the parameter e?
I have a movieclip called keyCButton that I want to add a keyboardEvent ("C" Key) to. This will play an animation from frames 2-30 with a sound. I have watched a few tutorials but still haven't gotten the correct information to make it work. The following is my code.
stage.addEventListener(KeyboardEvent.KEY_DOWN, cNote); function cNote(event:KeyboardEvent):void { if (event.keyCode == Keyboard.C)
[Code]....
When I try it with the SPACE instead of C i don't get errors but it still doesn't work
I'm loading an image in to my flex application and I'm trying to move the image via keyboard. I added an event listener to the application but the image will not move. How can I get it so that the flex 4 top level application can use the keyboard listener. The only possible way I'm figuring out how to get the keyboard event listener to work is add to to a text field.[code]Take into consideration I'm not even getting the trace on the keyboard event.
I need to use flash as3 to create a game, and I have tried to use 3 layer to load my swf. My game is in the third layer, and the first and second layers are just a preloader script.My problem is when the game is loaded onto the stage of first layer my KeyboardEvent function is not work until I press the stage.I have try to use Event.ADDED_TO_STAGE to solve it, but I also get a same error.this is my code for preloader
var request:URLRequest = new URLRequest("game.swf"); var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);[code]....................
I'm getting this weird error, don't know why, I've reduced the code to minimum and found the source of the problem but I don't understand why it errors.
i want to ask how that part of code would looked if there was keyboard evevt:
Code: function enable_disable(a){ if(a==0){field1.mouseEnabled=false;field2.mouseEnabled=false;field3.mouseEnabled=false;} if(a==1){field1.mouseEnabled=true;field2.mouseEnabled=true;field3.mouseEnabled=true;}}
[code]...
after clicking on a field you chose its selection is pernament you cant change it
I'm using ActionScript to listen for key presses and route to a method to handle them. It works fine in Flash Player Debugger 10.1, but does not work with the SWF in a browser. I've tried it with all sorts of keys: letters, numbers, etc. But I can't get it to work at all in the browser. I'm using Safari 5.1 and Firefox 3.6.8 on the Mac. Here's my relevant code:
It's my understanding that view states can be useful when switching the layout of design elements. Such as, a loading page as one state and the main application design in another state. Is this the correct use of them? Additionally, I have a label in State1 and I cannot figure out how to access that label via actionscript. labelID.text = "New Text"; is not working.
I need to add a rollover effect to the disabled state of a Spark button. This way, users can rollover the button and know why the button is disabled.I think I would have to override ButtonBase's getCurrentSkinState. Is there anyway to test if a mouse cursor is over a disabled button?
I'm using Flex 4.5 and trying to take advantage of the new state groups feature. I have two States (call them readType1 and readType2) that both belong to the same stateGroup (call it readOnly). There are several places where I'd like to do something based on the current state, and it would be the same thing for the two read states. [code]...
In my air project i used current state size is width="441" height="358" . i have link button like Singin then move to singin state (currentstate='singin')
So application resize into 616,919 . After that function finished move to current state like(currentstate='') But size not be changed . How can i set the size for current state?
I want to fade all the elements of the next state when transitioning from any state.I tried different things but I can't get it to work. And I don't want to manually add transitions for every state.
Which is a pretty small component and I have panelContainer:
[Code]...
Whilst the user is reading the warm and fuzzy welcome note in the welcome state I want to be creating the big expensive panels state so taht when we switch there is no delay. Before the panels state is set panelView is null but I presume there must be an IDefferredInstance floating around somewhere that I can use to kick off the creation of the view. How can I get hold of it?
I am trying to get converted to Actionscript 3 from AS2.In old versions of flash, you simply placed the sound in a keyframe inside the button on the over or down state. Worked fine, but not anymore.I guess the sound must be set up with actionscript and a listener.I understand linkage. how to make one sound on the over state and a different one on the down state?
I have 2 scenes. In both scenes, I have a movie clip that moves via keyboard control. If the goto next scene is triggered by the movie clip in the first scene the keyboard control works in the second. However, if I use a button to move to the next scene then there isn't any control over the movieclip in that scene. I've traced the keyCode in the second scene and it is picked up but the switch statement doesn't run. I'm migrating to Actionscript 3.0 and updating something I created in 2.0. I would like to do it without writing a class.
How do? Edit the field with numeric keypad, not a full keyboard my code: <s:TextInput text="{TransactionObject.cartao}" id="item" restrict="0123456789" /> app for Android and playbook
I get an error while extracting the asdoc of my flash professional project:
Code:
C:...Main.as(33): Spalte: 73 Fehler: Access of possibly undefined property D through a reference with static type Class. private var moveRightArray:Array = new Array(Keyboard.RIGHT, Keyboard.D); ^ C:...Main.as(33): Spalte: 73 Fehler: Access of possibly undefined property D through a reference with static type Class. private var moveRightArray:Array = new Array(Keyboard.RIGHT, Keyboard.D);
I'm a Flash newbie and I'm trying to get some keyboard action going. I've followed some tutorials, but nothing seems to work. To test it I created a brand new fla file and added the following code in the first frame:
[Code]...
The first trace ("Add listener") shows up in the debug output, but no matter which keys I press I can't get the function to be called. Am I doing it wrong?
