ActionScript 3.0 :: React To Simultaneous Key Presses?
Jan 26, 2011
I am familiar with taking in keyboard input in AS3. I was wondering if there was a way to capture and process simultaneous key presses.I don't mean when a user holds down, say, the up and left arrows at the same time and an object moves diagonally. I mean when they actually press down on the keys simultaneously, like in a video game where 2 simultaneous button presses performs a new action.Currently, I have a class that reads whenever a user presses a key and assigns it to an instance variable. Then, each frame, the class pushes the key into a storage array if the current key pressed doesn't match the last key pressed. Each key is stored for 60 frames before being dumped if it isn't processed.

I'm an intermediate flash user and I've made a file for my kids in class that has some sound on-off buttons. they are set to play once or loop depending on length by simple mouse click. they will play simultaneously if more than one is clicked individually on the page. I'm trying to make the page so the kids can just select the sound button icon, drag as many of them as they want (usually 2 -4 sounds at a time) into a box at the bottom of the page where they will then just play and loop. if they are dragged out of the box, that sound will stop. if another is dragged into the box it's sound will then join the ones that are already looping.

I am running Window 7 64 bit with 6 gb of RAM, two E5520 Xeons, two 10k raptors, one 320gb HD, and a ATI FirePro V5700. Brand New machine and a Fresh install of windows.
Everytime Photoshop CS4 is open it will cause Flash Cs4 to Crash. I can work in Flash without any issues until Photoshop is opened. Flash will usually crash in under 5 min with Photoshop open. I have tested this over and over and it is Photoshop causing Flash to crash. Does not matter whether I am running the 32 or 64 bit version of Photoshop. I am starting to believe it is a memory issue but I am not sure or how to fix if it is.I have tested the memory and it passed all tests. This is really killing my production time.

I am using mcl ( moviecliploader ) class to download images for a photo book;
when a user mouseover's a thumbnail, the corresponding fullsize img is downloaded;
PROBLEM: 1 - a user can move their mouse quickly over many thumbs;
2 - mcl class doesn't seem to have a way to stop downloading
3 - therefore it is realistic that the mcl could be forced to download 10-15 images simultaneously
4 - possibly the thumb that the user actually wants is last in the que;

I'm learning on how to make que loader system. I'm loading in 30 images at once when the swf loads onto stage that contains moderate tween animations. I was wondering would I get better performance if I only allowed to load 5 images at once then next set 5 ect ect. rather than to load 30 images at once? I can't tell because my computer is very good so I can't hardly tell. Is this common practice?

I'm not only new to the forums, but also rather new to AS 3.0, so this might be something really simple but I can't seem to figure it out Basically, what I'm trying to do it make a photogallery that's essentially a grid of thumbnails. When the user rolls over a thumbnail, I want it to grow in size just a little bit and when they click it would get much larger.Now, that part is simple, but when all of these size changes take place, I'm trying to make the other thumbnails get out of the way, instead of the usual overlapping that would occur. So my question is this:Is there some simple way to change the properties of those thumbnail MCs to avoid overlapping at all costs, while remaining on the stage? Or would I have to animate every possible combination separately on ever possible thumbnail?

I have two flash ads that need to look as though they are interacting. is there a way to make sure they load at the same time so they can sync every time? they do not need to communicate with each other just load simultaneously so the animation lines up. can local connection object work for this?I suppose I could stager load em and plan the animation accordingly if simultaneous load gives issues. is there a proper way to load one ad and then the second say 10 frames in, ya know?

I have changed the variable <MaxConnectionRate>2</MaxConnectionRate> base on the URL - "Limit connection requests",but more than 2 client can connect to the server.
Is that other settings to config to restrict the number of simultaneous users?

I'm trying to upload to amazon s3 using FileStream and UrlRequest.
But it seems I can only upload 2 files simultaneously.
Is there a reason for this? How can I work around this?
Also would this affect web service calls to a SOAP web service on the same domain?

Im in the final steps of my Flash game, now I have to take care of the music/sound.And, I figure out that I'd need to reproduce several sounds simultaneously, sounds like gun shots, explosions, screams, etc, however, these sounds are short, < 1 seconds.So, how many sounds can I reproduce at the same time?, and what would be the best approach (what class to use, how, tips, etc) to achieve this?, considering my situation.

I am trying to do a little multimedia player where I have at least 9 small videoclips that I would like to place and play - all controlled by AS 3.0.
It might even be more than 9 clips, but they will show randomly in 9 places. A movie can switch viewport too.
I will preload them all into buffers and I would like to play them randomly at the same time.
This means that there could be 9 equally sized areas showing small movieclips including sound and random times.
Like this:
[1][2][3]
[4][5][6]
[7][8][9]
So its 1 Flash canvas/player showing them all at the same time.
Is this possible or will it crash Flash to play 9 movies including their sound? The movies might be of different length and will have to be reset and played many times, but I cant prerender the result as its randomly generated from user input.
like in... an example code of where to start? I've been thinking that I could put all the parts into one "sprite movie" and the play from frame XYZ for each "window" - but not sure how or if it will work..

I have been been testing for keyboard events one key at a time. Now I want to test two keys being pressed or released at the same time. I am unclear on how to do this. Do I need to indicate this intention in the functions parameter
Code:

Currently my flash file will insert an object onto the stage when the user clicks onto the stage. each object will play and loop a sound (the user can select sounds and time before the sound loops for each object) but when I have many sounds playing at once, the sounds will suddenly stop and briefly come back before stopping again. Now I'm guessing there must be a maximum number for sounds simultaneously playing for a flash movie? If so, I'd like to know if there are any workarounds?At present, a sound playing about 2 times a second will be able to repeat roughly 30 times before it sound cuts out.
I added in functionality to stop a sound if it is attempting to trigger again in my play function to which I had a "cannot access a property or method of null object reference" output on the function and the sounds all started doing the same thing again. This happens the same as above, after 30 times playing 2 a second.Unless I've assessed the cause incorrectly, the only workarounds I can think of are to restrict the sound length and restrict the time before a sound loops - but this would ruin some of the aspects of what I wanted to create

My AS 3 program has multiple buttons. Users can select one and then immediately select another and this causes 2 threads that collide. Once one button is executing, I want the other buttons to ignore clicks.
The problems are twofold: 1) the first time the 2nd button attempts to execute (by checking lock), when it returns (from checking lock) and attempts to pick up processing where it left off, it seems to forget where it was and does not utlimately complete its task(s); possibly variables have been altered, it is difficult to say. That is, AS 3 is unable to successfully pickup where it left off on the first button. the second problem is that AS 3 incorrectly returns to button 2 after the lock condition is cleared. It persists and will execute that button.

I am making the board game Shogi in actionscript 2 and I have a question on how to detect a particular imput.I have a movie clip on the stage, I want it so that if I hold down the keyboard button "p" and then click on the movie clip, it will go to the movie clip's frame 2 (not the entire flash project's frame 2, just the particular icon's frame 2. I need this because I am using movie clips as game pieces and in Shogi, certain game pieces can be promoted. I also was wondering how to detect what frame it is on.

Essentially, I have flash content that scrolls on mouse wheel. It works fine, unless there is other content in the browser such that the browser's scrollbar is enabled - when that is the case, both the browser window AND my SWF scroll on mouse wheel. Is there any way to correct this behavior?
Similar question asked here:
disable mouse wheel scrolling while cursor over flex app?
which references the solution blogged about here:
[URL]
But the solution does not work on all browsers! While it works on some Windows browsers, it doesn't work at all on Mac OS X - it registers mouse wheel events in Firefox, but they are not getting fired at all in Chrome and Safari.
Now I know that (per the official Adobe InteractiveObject docs) mouse wheel is supposedly only supported on Windows systems, but the event is still fired by default on Mac OS X. Is this simultaneous scroll bug the reason it is not supported?
Edit: adding more info on above solution...
Note that the above solution basically uses ExternalInterface to send the following JavaScript to the "eval" function:
var browserScrolling;
function allowBrowserScroll(value) {
browserScrolling = value;

how flash handles multiple simultaneous objects being loaded? If I set two images loading into two empty movie clips in two consecutive lines of code, do they both load simultaneously or does the one that was called first load and then the second image load when the first has finished?

I have a large block of code in frame one of a movie. It executes, then the movie progresses to frame 2 and stops.I then have buttons at frame 2 that change the value in a string variable and send the movie back to frame 1 where it executes the code with the new value and proceeds to stop in frame 2 again.How can I eliminate this use of frame 2?How do I set it up so that I just re-run the code when the variable changes?I assume I can put all my code inside a function that gets called when the variable changes.

I'm re-writing an MXML item renderer in pure AS. A problem I can't seem to get past is how to have each item renderer react to a change on a static property on the item renderer class. In the MXML version, I have the following binding set up on the itemenderer:instanceProperty=callInstanceFunction(ItemRenderer.staticProperty)What would be the equivalent way of setting this up in AS (using BindingUtils, I assume)?PDATE:So I thought the following wasn't working, but it appears as if Flex is suppressing errors thrown in the instanceFunction, making it appear as if the binding itself is bad. indingUtils.bindSetter(instanceFunction, ItemRenderer, "staticProperty");However, when instanceFunction is called, already initialized variables on the given instance are all null, which was the cause of the errors referenced above.
