ActionScript 3.0 :: Passing Keystrokes From Air Browser To Flash Game?
Jan 11, 2011
I am accessing some games that my company built using a AIR browser (allowing us to sell an installable product on a CD, but keeping the content online for ease of maintenance). I can get the games to load, but i cant get them to accept keystrokes, ie: we have a tetris-like game that isnt getting any of the arrow key inputs. I'm fairly certain this has something to do with a focus issue, but I have no idea how to fix it.
I've written a little video game in Flex that runs in a browser. The player moves by pushing the arrow buttons on the keyboard, so I need to capture those keystrokes. In fact, the game action starts when the player presses one of those keys.In order to capture the keystrokes, the Flash/Flex application, not just the browser, needs to have the focus.How can I ensure that the application has the focus? I've implemented a bit of a hack: A "Begin" button you must click to start the game. The only point of this button is to ensure that the app has the focus.
What I want to do is to pass parameters from the browser to flash. I searched and seems like the best way is FlashVars. However, I have tried different codes and can't get Flash to detect the parameters. I decided to follow the example here and just copy and paste the whole thing (just changing the "main.swf" to my swf name): [URL]. The flash loads, but it only shows "param:" without anything else. I gathered that it probably is a more fundamental problem. (e.g. the way I am debugging, or some settings, etc.) I am using CS4 trial version AS3.
There's clearly a bunch of new stuff in Flash 10, I'm seeing a bunch in the Graphics class so far. Struggling a bit to reconcile it with what I know already but it looks useful - render lists and 3D transforms, etc - however I wondered if there are good arguments for targeting Flash 9 since I can definitely manage without all the new stuff I don't know. Like support on non-Windows devices, wide adoption of Flash 9 Vs 10, etc.
I have made a plattformgame in flash, and after I had published it I tested it (local) when it was embedded in a browser, and it hacks and laggs! But when I play it in the flash player it works just fine.
I removed all the heavy graphics, lowerd the fps to 30fps and removed all the code so now its just the bassis left (gravity, collision, key checking etc. and yes u should bounce on the walls giving a wall jump effect).[URL]
when I test my project in flash CS4, both the flash player and the authoring tool detect my keystrokes. Is there a way to make the authoring tool ignore key input while testing a movie, since I really only intend the key presses for the movie?
has anyone else found trace() to be much, much slower in CS4?
I am developing a non-real time browser RPG game (think Kingdom of Loathing) which would be played from within a Flash app. At first I just wanted to make the communication with server using simply URLLoader to tell PHP what I am doing, and using $_SESSION to store data needed in-between request. I wonder if it wouldn't be better to base it on a socket connection, an app residing on a server written in Java or Python.
The problem is I have never ever written such an app so I have no idea how much I'd have to "shift" my thoughts from simple responding do request (like PHP) to continuously working application. I won't hide I am also concerned about the memory and CPU usage of such Server app, when for example there would be hundreds of users connected. I've done some research. So, considering the fact I don't need real time data exchange, will it be wise to develop the server side part as socket server, not in plain ol' PHP?
I've been working for a month on a flash game, which should be manageable to play in a browser (light computation). This being said, I've noticed that in some browsers the game runs at what looks like 15 fps (the game should run in 80fps). This has been known to happen in IE9, and the quick fix was to add this line to the top of the html: <meta http-equiv="X-UA-Compatible" value="IE=9"> This was a quick-fix that forces IE into compatibility mode and greatly improved the fps (to about... 60, let's say). Still, I believe that the game is running slower than it should in every browser, which is evident when the html version is compared to the swf.
I am currently making for fun a racing game. When it started to get in shape, I decided to try it in a browser.
Now, when using CTRL+Enter or running the swf file, it was all working really smoothly. But when I ran it through a browser (when publishing, I generated html file and opened it in FireFox) it was extremely sloppy.
My first thought is that there are too many calculations which resulted in low fps. I downloaded and put a script to measure the fps. In both, IDE and browser, the movie was played back with max fps of 24. When I increased it to 50 it was still reaching max fps in both, yet in browser movie was still really sloppy (though it was a little bit better than with max fps being 24). When raised to 100, playback in browser was capped at 60fps on different computers so I guess it's a flash player cap. Movie was still not smooth at all.
How do I make my flash game keep picture quality when browser is resized.I built a flash game combining using actionscript and whenever the player or browser is resized it loses quality.Is there a way so, if the browser for example is made smaller the game's picture still keeps its display quality
Some of my Flash application components require to intercept Ctrl + F4 keyboard events. Unfortunately, the KeyboardEvent is not caught when running the app under IE since it is conflicting with the IE native shortcut (closing the active tab). Is there a way (ideally relying on Flash principles) to intercept such keystrokes?
I made a game as the same site URL..Anyone knows how to prevent user open and play game on multiple browser windows at a time?I used flash control to embed flash into aspx page and connect to sql server
I'm currently having a problem with preloading. What I have is: 1. Preloader -> an SWF preloader, made in Adobe Flash CS5 2. GUI -> an SWF file containing the user interface, made in Adobe Flash CS5 3. Game -> an SWF containing actual game logic, made in Flash Develop
The preloader SWF should preload both GUI and Game. I can do this, no problem. The problem however is: I need to be able to control the GUI from the Game. So how can I access the GUI from the Game? In particular the main movieclip in the GUI which contains every interface screen. How can a script inside a SWF communicate with another SWF (all in the same file)?
I have benn programming in AS2 for a while, but I'm moving to AS3, and I'm having some trouble with syntax and mostly with management of parameters and variables (actually I tried to work with functions in packages without good results T.T). The game has four different types of shooters, and all of them use the same bullet (shoot function). I have succeeded on disappearing the target (a coin in this case) when it is hit by the bullet, but the problem is that I can't quite find the way to dissapear the bullet properly. I keep receiving this message:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. at flash.display:isplayObjectContainer/removeChild() at eco_adm9_fla::MainTimeline/moveBullet()
I need to find a way to detect keystrokes when the flash file is not selected and send that information to an .swf file. The file would be stored locally (not on the internet).
I started off game development on Android about a year ago and want to expand to developing browser games as well. Is flash worth learning? Or should I go for using an engine like Unity and learn game development in c#. Mostly I'm just worried that I would be wasting my time learning flash if I'm not going to get much use from it.
I am making a password protected site. I have made the site function that the proper password is required and once submitted the user gets linked to the next page.I want the password text box to not accept anything from the keyboard except for the ctrl+paste function. how to disable certain keystrokes using AS3? I want the letters A-Z disabled with the exception of the letter V.
If I wanted to code a desktop-based game, I could pull some XNA code and UDP sockets and make a decent multiplayer game. I would have an extremely clear of how to code the game I wanted.But if I wanted to code a browser-based online multiplayer game, how would I do it?ou can't use XNA....I've been looking at some questions and I'm seeing PHP and ASP.NET and Silverlight and Flash and Java as the alternative languages...I really don't understand how it works. I mean, for a desktop-based game, you're opening a UDP socket and accepting clients and transferring data, updating player states, drawing the results using XNA. But in a browser, how do you open a socket and stuff? How does that concept work, communicating to people in realtime through a web-browser.
I'm working on a game and want the freedom to choose between UDP and TCP connections in the future when I decide to add multiplayer. I'm not sure how something like this would work in the browser with security.
There are two scenarios I can think of for multiplayer. The first is that a player becomes the host of the game (in the browser) and thus would need to communicate with other players directly via TCP or UDP. This would save me on bandwidth costs.
The second scenario would be to have the web server host the game and pass messages back and forth to the clients again via TCP or UDP.
Do Flash or Java applets let me do something like this? If not is there an alternative I can use for the browser or am I stuck with moving to providing a game download and installation?
Is it possible to handle keystrokes WHILE dragging? I found this to be impossible, because hitting a key always fires an "onRelease" or "onReleaseOutside" event on the dragged movieclip when releasing the key - intterupting the drag operation. What I want to do is something like this: Drag and Drop a Movieclip and while dragging it I want to be able to flip it with a keystroke.
I have a little application running and I want the Page Up and Down Buttons to do something when pressed. For some reason though, when I am testing the movie and I press the buttons nothing will happen. I can't even trace anything.It seems to be the case with all of the "Document Keys" (Home, End, Delete, PgUp, PgDown), but not with any of the others.
Can keylisteners be used to record keystrokes for later playback? If not, what can? The goal is to develop a way for individuals to make their own music via keypresses. For example: The R key is pressed to start the recording of the user's keyboard, with each keystroke assigned to play a different movieclip/audio, etc. The S key is then pressed to stop the recording. Lastly, the P key is pressed to play those movieclips/audio,etc. in their recorded sequence at the enjoyment of the individiual user.

On the very first frame in my .swf I have over 3.000 lines of code, mostly just a bunch of functions and variables.
I'm closing in to the completion of my game and I'm about to setup a preloader. However, I was wondering, how will all that code affect the preloader when the game is being loaded in a browser?
Will it cause a slight performance issue at the beginning or should I setup all that code on an empty frame right after the preloader?
I'm learning Flash to make a website for one of the companies I work forI have a decent portfolio page that loads content information from an .xml document. I'm just thrilled that it works, but my boss wants a little more.He wants to be able to scroll through the entries with left and right keystrokes. In the glow of my recent array-building triumph, I told him, 'sure, I can do that!' ...but I can't. I can't figure out how to make the left and right keys go to previous or next entries. With previous problems I've been able to find an answer by searching google, but I'm stuck on this one.
Here's my code: var titleArray:Array = new Array(); var descriptionArray:Array = new Array();
I have a movie with a blank mc on the stage. I have it set up so that when you press the RIGHT keyboard key it loads another movie in that mc. Here's the code for that:
If I have more than one movie, how do I code it so that when I press the RIGHT key again it loads another movie as well as goes back when I press the LEFT?
I'm creating a game at the moment for my university course and it involves the player character jumping on top of boxs twice to break them as opposed to just once.What would be the most efficient/simple way of writing this in Actionscript 3.
I am thinking of developing of a game like this: [URL]... Do you have any idea - by which game engine I may develop this type of games? I am not sure whether I have to use any 3d physics engine? I think JiglibFlash may be useful, but I am not sure.
