• Optimizing transition/movement smoothness for a 2D flash game.

  - by Tom

  Update 6: Fenomenas suggested me to re-create everything as simple as possible. I had my doubts that this would make any difference as the algorithm remains the same, and performance did not seem to be the issue. Anyway, it was the only suggestion I got so here it is: 30 FPS: http://www.feedpostal.com/test/simple/30/SimpleMovement.html 40 FPS: http://www.feedpostal.com/test/simple/40/SimpleMovement.html 60 FPS: http://www.feedpostal.com/test/simple/60/SimpleMovement.html 100 FPS: http://www.feedpostal.com/test/simple/100/SimpleMovement.html The code: package { import flash.display.Sprite; import flash.events.Event; import flash.events.KeyboardEvent; import flash.utils.getTimer; [SWF(width="800", height="600", frameRate="40", backgroundColor="#000000")] public class SimpleMovement extends Sprite { private static const TURNING_SPEED:uint = 180; private static const MOVEMENT_SPEED:uint = 400; private static const RADIAN_DIVIDE:Number = Math.PI/180; private var playerObject:Sprite; private var shipContainer:Sprite; private var moving:Boolean = false; private var turningMode:uint = 0; private var movementTimestamp:Number = getTimer(); private var turningTimestamp:Number = movementTimestamp; public function SimpleMovement() { //step 1: create player object playerObject = new Sprite(); playerObject.graphics.lineStyle(1, 0x000000); playerObject.graphics.beginFill(0x6D7B8D); playerObject.graphics.drawRect(0, 0, 25, 50); //make it rotate around the center playerObject.x = 0 - playerObject.width / 2; playerObject.y = 0 - playerObject.height / 2; shipContainer = new Sprite(); shipContainer.addChild(playerObject); shipContainer.x = 100; shipContainer.y = 100; shipContainer.rotation = 180; addChild(shipContainer); //step 2: install keyboard hook when stage is ready addEventListener(Event.ADDED_TO_STAGE, stageReady, false, 0, true); //step 3: install rendering update poll addEventListener(Event.ENTER_FRAME, updatePoller, false, 0, true); } private function updatePoller(event:Event):void { var newTime:Number = getTimer(); //turning if (turningMode != 0) { var turningDeltaTime:Number = newTime - turningTimestamp; turningTimestamp = newTime; var rotation:Number = TURNING_SPEED * turningDeltaTime / 1000; if (turningMode == 1) shipContainer.rotation -= rotation; else shipContainer.rotation += rotation; } //movement if (moving) { var movementDeltaTime:Number = newTime - movementTimestamp; movementTimestamp = newTime; var distance:Number = MOVEMENT_SPEED * movementDeltaTime / 1000; var rAngle:Number = shipContainer.rotation * RADIAN_DIVIDE; //convert degrees to radian shipContainer.x += distance * Math.sin(rAngle); shipContainer.y -= distance * Math.cos(rAngle); } } private function stageReady(event:Event):void { //install keyboard hook stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown, false, 0, true); stage.addEventListener(KeyboardEvent.KEY_UP, keyUp, false, 0, true); } private final function keyDown(event:KeyboardEvent):void { if ((event.keyCode == 87) && (!moving)) //87 = W { movementTimestamp = getTimer(); moving = true; } if ((event.keyCode == 65) && (turningMode != 1)) //65 = A { turningTimestamp = getTimer(); turningMode = 1; } else if ((event.keyCode == 68) && (turningMode != 2)) //68 = D { turningTimestamp = getTimer(); turningMode = 2; } } private final function keyUp(event:KeyboardEvent):void { if ((event.keyCode == 87) && (moving)) moving = false; //87 = W if (((event.keyCode == 65) || (event.keyCode == 68)) && (turningMode != 0)) turningMode = 0; //65 = A, 68 = D } } } The results were as I expected. Absolutely no improvement. I really hope that someone has another suggestion as this thing needs fixing. Also, I doubt it's my system as I have a pretty good one (8GB RAM, Q9550 QuadCore intel, ATI Radeon 4870 512MB). Also, everyone else I asked so far had the same issue with my client. Update 5: another example of a smooth flash game just to demonstrate that my movement definitely is different! See http://www.spel.nl/game/bumpercraft.html Update 4: I traced the time before rendering (EVENT.RENDER) and right after rendering (EVENT.ENTER_FRAME), the results: rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 14 ms rendering took: 14 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 24 ms rendering took: 18 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 232 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms rendering took: 14 ms rendering took: 16 ms rendering took: 12 ms rendering took: 14 ms rendering took: 12 ms The range is 12-16 ms. During these differences, the shocking/warping/flickering movement was already going on. There is also 1 peak of 232ms, at this time there was a relatively big warp. This is however not the biggest problme, the biggest problem are the continuous small warps during normal movement. Does this give anyone a clue? Update 3: After testing, I know that the following factors are not causing my problem: Bitmap's quality - changed with photoshop to an uglier 8 colours optimized graphic, no improvement at all. Constant rotation of image while turning - disabled it, no improvement at all Browser rendering - tried to use the flash player standalone, no improvement at all I am 100% convinced that the problem lies in either my code or in my algorithm. Please, help me out. It has been almost two weeks (1 week that I asked this question on SO) now and I still have to get my golden answer. Update 1: see bottom for full flex project source and a live demo demonstrating my problem. I'm working on a 2d flash game. Player ships are created as an object: ships[id] = new GameShip(); When movement and rotation information is available, this is being directed to the corresponding ship: ships[id].setMovementMode(1); //move forward Now, within this GameShip object movement works using the "Event.ENTER_FRAME" event: addEventListener(Event.ENTER_FRAME, movementHandler); The following function is then being run: private final function movementHandler(event:Event):void { var newTimeStamp:uint = UtilLib.getTimeStamp(); //set current timeStamp var distance:Number = (newTimeStamp - movementTimeStamp) / 1000 * movementSpeed; //speed = x pixels forward every 1 second movementTimeStamp = newTimeStamp; //update old timeStamp var diagonalChange:Array = getDiagonalChange(movementAngle, distance); //the diagonal position update based on angle and distance charX += diagonalChange[0]; charY += diagonalChange[1]; if (shipContainer) { //when the container is ready to be worked with shipContainer.x = charX; shipContainer.y = charY; } } private final function getDiagonalChange(angle:Number, distance:Number):Array { var rAngle:Number = angle * Math.PI/180; //convert degrees to radian return [Math.sin(rAngle) * distance, (Math.cos(rAngle) * distance) * -1]; } When the object is no longer moving, the event listener will be removed. The same method is being used for rotation. Everything works almost perfect. I've set the project's target FPS to 100 and created a FPS counter. According to the FPS counter, the average FPS in firefox is around 100, while the top is 1000 and the bottom is 22. I think that the bottom and top FPSs are only happening during the initialization of the client (startup). The problem is that the ship appears to be almost perfectly smooth, while it should be just that without the "almost" part. It's almost as if the ship is "flickering" very very fast, you can't actually see it but it's hard to focus on the object while it's moving with your eyes. Also, every now and then, there seems to be a bit of a framerate spike, as if the client is skipping a couple of frames, you then see it quickly warp. It is very difficult to explain what the real problem is, but in general it's that the movement is not perfectly smooth. So, do you have any suggestions on how to make the movement or transition of objects perfectly smooth? Update 1: I re-created the client to demonstrate my problem. Please check it out. The client: http://feedpostal.com/test/MovementTest.html The Actionscript Project (full source): http://feedpostal.com/test/MovementTest.rar An example of a smooth flash game (not created by me): http://www.gamesforwork.com/games/swf/Mission%20Racing_august_10th_2009.swf It took me a pretty long time to recreate this client side version, I hope this will help with solving the problem. Please note: yes, it is actually pretty smooth. But it is definitely not smooth enough.

• Gui problem after rewriting to MVC

  - by trevor_nise

  I'm practicing MVC style programming. I have a Mastermind game in a single file, working with no problems (maybe apart of the fact that "Check" button is invisible at start). http://paste.pocoo.org/show/226726/ But when I've rewritten it to model, view, controller files - when I click on empty Pin (that should be updated, and repainted with new color) - noting happens. Can anybody see any problems here ? I've tried placing repaint() in different places, but it simply does not work at all :/ Main : public class Main { public static void main(String[] args){ Model model = new Model(); View view = new View("Mastermind", 400, 590, model);

• What is asloader.exe and why does it want to run elevated?

  - by wscholine

  I have Vista 64-bit ultimate on my home computer, with accounts for each family member. Most are administrators but I have one kid with a plain user account. When she logs in she gets a prompt that asloader wants to run but needs administrator. I gather that this has something to do with either the ASUS mobo (P6T Deluxe V2) or the ATI graphics card (Sapphire 4890 OC). Can anyone explain what asloader does, and suggest how I might configure something to suppress the prompt my kid gets? Thanks.

• HTTP client - HTTP 405 error "Method not allowed". I send a HTTP Post but for some reason HTTP Get i

  - by Shino88

  Hey I am using apache library. I have created a class which sends a post request to a servlet. I have set up the parameters for the client and i have created a HTTP post object to be sent but for some reason when i excute the request i get a reposnse that says the get method is not supported(which is true cause i have only made a dopost method in my servlet). It seems that a get request is being sent but i dont know why. The post method worked before but i started gettng http error 417 "Expectation Failed" which i fixed by adding paramenters. below is my class with the post method. P.s i am developing for android. public class HTTPrequestHelper { private final ResponseHandler<String> responseHandler; private static final String CLASSTAG = HTTPrequestHelper.class.getSimpleName(); private static final DefaultHttpClient client; static{ HttpParams params = new BasicHttpParams(); params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); params.setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, HTTP.UTF_8); ///params.setParameter(CoreProtocolPNames.USER_AGENT, "Android-x"); params.setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 15000); params.setParameter(CoreConnectionPNames.STALE_CONNECTION_CHECK, false); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register( new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); schemeRegistry.register( new Scheme("https", SSLSocketFactory.getSocketFactory(), 443)); ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager(params, schemeRegistry); client = new DefaultHttpClient(cm,params); } public HTTPrequestHelper(ResponseHandler<String> responseHandler) { this.responseHandler = responseHandler; } public void performrequest(String url, String para) { HttpPost post = new HttpPost(url); StringEntity parameters; try { parameters = new StringEntity(para); post.setEntity(parameters); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } BasicHttpResponse errorResponse = new BasicHttpResponse( new ProtocolVersion("HTTP_ERROR", 1, 1), 500, "ERROR"); try { client.execute(post, this.responseHandler); } catch (Exception e) { errorResponse.setReasonPhrase(e.getMessage()); try { this.responseHandler.handleResponse(errorResponse); } catch (Exception ex) { Log.e( "ouch", "!!! IOException " + ex.getMessage() ); } } } I tried added the allow header to the request but that did not work as well but im not sure if i was doing right. below is the code. client.addRequestInterceptor(new HttpRequestInterceptor() { @Override public void process(HttpRequest request, HttpContext context) throws HttpException, IOException { //request.addHeader("Allow", "POST"); } });

• Windows 7 Drivers for Hp Tx2000 tablet Pc

  - by iceman

  Has anyone tried the new tablet features of windows 7 on the Hp tablet TX2001au : http://h10025.www1.hp.com/ewfrf/wc/product?product=3653674&lc=en&dlc=&cc=us&lang=&softwareitem=ob-77258-1&dest_page=product&os=4062 ? Hp has only Vista drivers and no Windows 7 drivers yet : link and link The main issues after installing Windows 7 is that the graphics card (Nvidia GeForce Go 6150) and the coprocessor are not detected.The latest 191.07 GeForce/ION Driver installer says that it cannot find any compatible hardware by the way, i still haven't been able to get Xp running on this . The Nvidia GeForce Go 6150 driver seems to be customized by HP !! If you install the laptopvideo2go.com/ drivers on Xp(after MS nags that it can't verify the publisher of the driver) , it shows the blue screen of death. Is there a way to debug the BSOD ?

• New build won't POST, no video, no beeps

  - by Nate Koppenhaver

  Specs: Motherboard: MSI 760GM-P23 FX Integrated graphics (on MoBo) CPU: AMD Athlon II x4 640 RAM: GeIL Pristine 4GB DDR3 Case/PSU: TOPOWER TP-4107BB-400 Is not POSTing, no video output, no beeps. When RAM is removed, 3 beeps. I have tried removing and replacing the CPU and all the power cables with no change. Resetting the BIOS (by removing and replacing the battery) did nothing as well. Is there something I'm forgetting (1st time building from components), or could one of the components be bad? EDIT: New development: with CPU and RAM installed correctly, it will turn on lights and fans (still no POST) and after running for a minute or so it will turn off and the PSU will make a buzzing noise that ceases only when unplugged.

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Web Browsers Software Tools Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers Drawings If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.

• Can my laptop run dual 1080p (Sony Vaio - Nvidia 330M)

  - by Charlino

  I am looking to buy a monitor to setup dual monitors for my laptop and was wondering if my laptop could handle 2 x 1080p. I have a Sony Vaio VPCF116FG which has a Nvidia GeForce 330M chip and 1GB dedicated graphics memory. The laptop also has a Intel® Core™ i7-720QM Processor (1.60 GHz with Turbo Boost up to 2.80 GHz) but I don't know if that's relevant(?). The laptop screen has a native resolution of 1080p (1920 x 1080) so I'll be looking at buying a external monitor with 1080p to connect up using a HDMI cable. So, the question is, will my laptop be able to handle it's own 1080p screen AND an external 1080p screen? TIA, Charles

• Install 64-bit Ubuntu or 32-bit?

  - by nitbuntu

  I'll be receiving a new notebook in a few days and was planning on running Ubuntu on it as it's compatible and the notebook has no OS pre-installed. The specifications are: Core 2 Duo, T6600, 4 GB RAM, Intel integrated graphics. I know a year or two ago, running a 64-bit version of Ubuntu was not advised due to much of the applications and plugins (e.g. Flash) only running on 32-bit. Is this still the case? Would I get better performance with 64-bit Ubuntu since I have 4 GB of RAM? Are there any downsides anymore?

• Computer starts, POSTs normal, no video

  - by Annath

  So, I recently tried to start up an old computer of mine. It would not power on, so I replaced the PSU. When I powered it on, all the fans spun up and the POST beeps indicated a normal startup. The problem was there was no video output. Every couple of minutes, I hear the post code again. I think it is restarting after POST, but without video I have no idea why. Does anyone have an idea as to why this is happening, and how to fix it? EDIT: The video card is a PCI-e card. There is no integrated graphics on the motherboard. If I remove the video card, the POST indicates a missing card. When I put it back, it goes back to normal, so I know that it recognizes that the card exists.

• Windows 7: app crashing/hanging on "save as" dialog

  - by Fuxi

  now this is really annoying - I'm having a global problem in Windows 7: when using the system's "save as"-file dialog, the main app will just hang. the mouse-cursor is showing progress, the whole app is hanging and I need to terminate it manually. it's happening with every app! (notepad, word, graphics app). I'm assuming it's something with the system enumerating the harddisk-drivenames or something. any idea how to fix this? by the way - when viewing the problem details - it's telling the module - it's msonsext.dll, looks like some office thing to me.

• Stuck on Checking battery state at startup in Ubuntu, have splash screen no startup

  - by jeffhsu3

  I am running Ubuntu 10.04 LTS. When I boot up the computer it goes to the splash but there is no login screen, just the purple background and the mouse cursor. "Checking battery state" is the last line that does not have an "[OK]". When I press Ctr-alt-shift-F1 I can login and sudo stop gdm and startx. However this makes it so that the applets don't show. Error: "The panel encountered a problem while loading "OAFIID:GNOME_notificationAreaApplet" and does it for every single applet. Everything else works fine though. I get a EHCI: BIOS handoff failed twice in the dmesg as well. The laptop has intel mobile integrated graphics. UPDATE: Now my desktop has the exact same problem. Things that I have tried: Changing to GRUB_CMDLINE_LINUX_DEFAULT="i915.modeset=1 acpi=off"

• Windows 7 and laptop overheating

  - by Nikola

  I am using ArchLinux 99% of my working time, and laptop has absolutely no heating problems. But when it comes to using Windows 7, laptop starts heating and one can clearly hear CPU fan working like crazy. I think it has something to do with CPU itself, because on Linux I can simply manipulate with CPU governors (eg. set it to ondemand), but I can't seem to find any similar software to do the same thing as if in Linux. Or, the heating might be caused because of two graphics cards or something? CPU-Z results http://valid.canardpc.com/show_oc.php?id=2310815 Any idea/solution regarding this issue?

• jQTouch flicker on iPad with pixel doubling

  - by websfear

  I'm using jQTouch on an iPhone application and one of our requirements is to make this work in the iPad with pixel doubling. I believe there's a bug/issue with jQTouch on the iPad (running within an app UIWebView, but pixel doubled) that causes the screen to flicker during transitions. Pretty much every transition has a stutter/flicker on it. Has anyone else experienced this? I also started seeing this flicker on some Android devices as well.

• How to black out second monitor when playing a full screen game?

  - by Gary

  I've got two monitors. When I play a full screen game in my primary monitor, the second monitor still shows the Windows desktop. How can I black out the second monitor so that it doesn't show anything at all? My graphics card is from ATI. I'm running Windows 7 in Boot Camp on an iMac. I don't know if this makes a difference, however, as any solution to my question will do, really. For instance, is there a tiny app that I could run to disable the second monitor for a while? I'd rather not have to open Windows display settings every time I run a game and disable the monitor that way, though.

Headings, header and footer, and captions are printing on the page, along with any graphics such as border styles applied to the style, but the text itself doesn't print -- except for en dashes. The text is pretty basic -- a justified Calibri style. Images are their own style, a centered paragraph item. There's no floating image boxes or text boxes going on, everything's a paragraph style. It's not a print driver issue. I get identical behavior on both a HP and Brother laser printer. It's also not a paragraph-level style issue; I've inserted enough dummy text to move a printing paragraph on a page with no images to the next page, which has an image, and the paragraph does not print on the next page. Has anyone run into an issue like this and knows the solution?

• How can you invert the colors of a PDF?

  - by legr3c

  I need to invert all the colors of a PDF document (background, text, graphics, and images). I want it persistent in the file so the inverted viewing options, that some viewers offer, won't help. Rasterizing the document and using image manipulation software is also not an option. I read somewhere that this can be done with the Enfocus PitStop plugin for Acrobat. However I didn't see a corresponding command anywhere. Am I missing something? Then I read that the ARTS PDF Crackerjack plugin for Acrobat offers negative printing so I tried that, too. The option is there but it simply doesn't work. I have been searching for very long for a way to do this. It seems like a common enough task but I just can't find out how to do it. Are there maybe any virtual printer drivers or something of the sort that support negative printing? Can anyone help?
