• Frameskipping in Android gameloop causing choppy sprites (Open GL ES 2.0)

  - by user22241

  I have written a simple 2d platform game for Android and am wondering how one deals with frame-skipping? Are there any alternatives? Let me explain further. So, my game loop allows for the rendering to be skipped if game updates and rendering do not fit into my fixed time-slice (16.667ms). This allows my game to run at identically perceived speeds on different devices. And this works great, things do run at the same speed. However, when the gameloop skips a render call for even one frame, the sprite glitches. And thinking about it, why wouldn't it? You're seeing a sprite move say, an average of 10 pixels every 1.6 seconds, then suddenly, there is a pause of 3.2ms, and the sprite then appears to jump 20 pixels. When this happens 3 or 4 times in close succession, the result is very ugly and not something I want in my game. Therfore, my question is how does one deal with these 'pauses' and 'jumps' - I've read every article on game loops I can find (see below) and my loops are even based off of code from these articles. The articles specifically mention frame skipping but they don't make any reference to how to deal with visual glitches that result from it. I've attempted various game-loops. My loop must have a mechanism in-place to allow rendering to be skipped to keep game-speed constant across multiple devices (or alternative, if one exists) I've tried interpolation but this doesn't eliminate this specific problem (although it looks like it may mitigate the issue slightly as when it eventually draws the sprite it 'moves it back' between the old and current positions so the 'jump' isn't so big. I've also tried a form of extrapolation which does seem to keep things smooth considerably, but I find it to be next to completely useless because it plays havoc with my collision detection (even when drawing with a 'display only' coordinate - see extrapolation-breaks-collision-detection) I've tried a loop that uses Thread.sleep when drawing / updating completes with time left over, no frame skipping in this one, again fairly smooth, but runs differently on different devices so no good. And I've tried spawning my own, third thread for logic updates, but this, was extremely messy to deal with and the performance really wasn't good. (upon reading tons of forums, most people seem to agree a 2 thread loops ( so UI and GL threads) is safer / easier). Now if I remove frame skipping, then all seems to run nice and smooth, with or without inter/extrapolation. However, this isn't an option because the game then runs at different speeds on different devices as it falls behind from not being able to render fast enough. I'm running logic at 60 Ticks per second and rendering as fast as I can. I've read, as far as I can see every article out there, I've tried the loops from My Secret Garden and Fix your timestep. I've also read: Against the grain deWITTERS Game Loop Plus various other articles on Game-loops. A lot of the others are derived from the above articles or just copied word for word. These are all great, but they don't touch on the issues I'm experiencing. I really have tried everything I can think of over the course of a year to eliminate these glitches to no avail, so any and all help would be appreciated. A couple of examples of my game loops (Code follows): From My Secret Room public void onDrawFrame(GL10 gl) { //Rre-set loop back to 0 to start counting again loops=0; while(System.currentTimeMillis() > nextGameTick && loops < maxFrameskip) { SceneManager.getInstance().getCurrentScene().updateLogic(); nextGameTick += skipTicks; timeCorrection += (1000d / ticksPerSecond) % 1; nextGameTick += timeCorrection; timeCorrection %= 1; loops++; } extrapolation = (float)(System.currentTimeMillis() + skipTicks - nextGameTick) / (float)skipTicks; render(extrapolation); } And from Fix your timestep double t = 0.0; double dt2 = 0.01; double currentTime = System.currentTimeMillis()*0.001; double accumulator = 0.0; double newTime; double frameTime; @Override public void onDrawFrame(GL10 gl) { newTime = System.currentTimeMillis()*0.001; frameTime = newTime - currentTime; if ( frameTime > (dt*5)) //Allow 5 'skips' frameTime = (dt*5); currentTime = newTime; accumulator += frameTime; while ( accumulator >= dt ) { SceneManager.getInstance().getCurrentScene().updateLogic(); previousState = currentState; accumulator -= dt; } interpolation = (float) (accumulator / dt); render(interpolation); }

  Just when you feel like you’ve seen it all, some guy comes along and shows you how he can play original PlayStation games on his ebook reader. Check out the video to see the surprisingly full-speed–albeit black and white–graphics in action. The secret sauce in Sean’s cool setup? He’s rooted the device and installed Free PlayStation Emulator (FPSE) on it–along with the NoRefresh hack–to enjoy touch-screen controls and PS emulation. The whole thing is shockingly smooth; once you get past the choppy intro videos, the games run at full speed. [via Hack A Day] HTG Explains: Why Do Hard Drives Show the Wrong Capacity in Windows?

• TFS 2010 SDK: Integrating Twitter with TFS Programmatically

  - by Tarun Arora

  Technorati Tags: Team Foundation Server 2010,TFS API,Integrate Twitter TFS,TFS Programming,ALM,TwitterSharp   Friends at ‘Twitter Sharp’ have created a wonderful .net API for twitter. With this blog post i will try to show you a basic TFS – Twitter integration scenario where i will retrieve the Team Project details programmatically and then publish these details on my twitter page. In future blogs i will be demonstrating how to create a windows service to capture the events raised by TFS and then publishing them in your social eco-system. Download Working Demo: Integrate Twitter - Tfs Programmatically   1. Setting up Twitter API Download Tweet Sharp from => https://github.com/danielcrenna/tweetsharp  Before you can start playing around with this, you will need to register an application on twitter. This is because Twitter uses the OAuth authentication protocol and will not issue an Access token unless your application is registered with them. Go to https://dev.twitter.com/ and register your application   Once you have registered your application, you will need ‘Customer Key’, ‘Customer Secret’, ‘Access Token’, ‘Access Token Secret’ 2. Connecting to Twitter using the Tweet Sharp API Create a new C# windows forms project and add reference to ‘Hammock.ClientProfile’, ‘Newtonsoft.Json’, ‘TweetSharp’ Add the following keys to the App.config (Note – The values for the keys below are in correct and if you try and connect using them then you will get an authorization failure error). Add a new class ‘TwitterProxy’ and use the following code to connect to the TwitterService (Read more about OAuthentication - http://dev.twitter.com/pages/auth) using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Configuration;using TweetSharp; namespace WindowsFormsApplication2{ public class TwitterProxy { private static string _hero; private static string _consumerKey; private static string _consumerSecret; private static string _accessToken; private static string _accessTokenSecret;  public static TwitterService ConnectToTwitter() { _consumerKey = ConfigurationManager.AppSettings["ConsumerKey"]; _consumerSecret = ConfigurationManager.AppSettings["ConsumerSecret"]; _accessToken = ConfigurationManager.AppSettings["AccessToken"]; _accessTokenSecret = ConfigurationManager.AppSettings["AccessTokenSecret"];  return new TwitterService(_consumerKey, _consumerSecret, _accessToken, _accessTokenSecret); } }} Time to Tweet! _twitterService = Proxy.TwitterProxy.ConnectToTwitter(); _twitterService.SendTweet("Hello World"); SendTweet will return the TweetStatus, If you do not get a 200 OK status that means you have failed authentication, please revisit the Access tokens. --RESPONSE: https://api.twitter.com/1/statuses/update.json HTTP/1.1 200 OK X-Transaction: 1308476106-69292-41752 X-Frame-Options: SAMEORIGIN X-Runtime: 0.03040 X-Transaction-Mask: a6183ffa5f44ef11425211f25 Pragma: no-cache X-Access-Level: read-write X-Revision: DEV X-MID: bd8aa0abeccb6efba38bc0a391a73fab98e983ea Cache-Control: no-cache, no-store, must-revalidate, pre-check=0, post-check=0 Content-Type: application/json; charset=utf-8 Date: Sun, 19 Jun 2011 09:35:06 GMT Expires: Tue, 31 Mar 1981 05:00:00 GMT Last-Modified: Sun, 19 Jun 2011 09:35:06 GMT Server: hi Vary: Accept-Encoding Content-Encoding: Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Transfer-Encoding: chunked   3.

• Does Google include the time to load images, for a single page, as part of the page speed?

  - by Pure.Krome

  we all know that Google's affects your page rank with the load time of a page. How? That's part of the secret sauce. But we know that page speed is a serious factor. So - what is considered the speed of a page? Is it just the first (and main) html file which the GET receives? Or does it also include loading of images as part of that speed. so for example... GET /index.htm <- takes 0.45 seconds to retrieve (including DNS lookup before). robot parses page.. see's there's a single main image.... GET /img/main.png <- takes 5 seconds to download. is the page speed for that resource, 0.45 seconds OR 5.45 seconds? I understand Javascript is not fired .. but are any of these external resources all downloaded and part of the page speed?

• Network Multiplayer in Flash

  - by shadowprotocol

  Flash has come a long way in the last decade, and it's a well-kept secret getting a flash game to connect to a multi-client server for chat and/or basic avatar movement in real time. Why has the industry as a whole not made this a common-knowledge type of thing yet? We keep pushing to the web but I am finding it incredibly difficult gathering learning material on this subject. Sure, I can find multi-client server socket tutorials in various languages (using select statements and/or threads to handle multiple socket connections), but in regards to Flash applications inside of a browser? NOPE! Can everyone please share what they know? :] It's a subject I'd really love to get into but I'm afraid I just honestly don't know enough about how to do it. Thanks!

• Do I need to install a package (openSWAN or strongSWAN maybe) to use ipsec?

  - by user68886

  I want to connect to a windows share that only accepts ipsec transport mode. I have a list of security policies and a shared secret. I've skimmed through the man page on ipsec.conf on the web and it seems to be the place to put these polices. If ipsec is part of the kernel (and I think it is, I'm using Ubuntu 12.04) do I need to install some other package in order to get this working? I'm guessing it's either openSWAN or strongSWAN but don't know the difference.

I ran out of ideas why it isn't working.

• How to send credentials to linkedIn website and get oauth_verifier without signing in again [closed]

  - by akash kumar

  I am facing a problem sending credentials to another website so that I can login the user (automatically, not clicked on sign in here) and get an oauth_verifier value. I want to send the email address and the password through a form (submit button) from my website (e.g. a Liferay portal) to another website (e.g. LinkedIn), so that it automatically returns an oauth_verifier to my website. That means I don't want the user of my website to submit his email and password to LinkedIn again. My goal is to take the email and password of the user in my website and show the user his LinkedIn connection, message, job posting (again, in my website, not LinkedIn). I dont want the user redirected to the LinkedIn website to sign in there and then come back to my website. I have taken a consumer key and a secret key from LinkedIn for my web aplication. I am using the LinkedIn API and getting oauth_verifier for access token but in order to login, I have to take user to LinkedIn to sign in, while I want it to happen in the backend.

• Interesting conversation about the nature of info-wars

  - by Malcolm Anderson

  Over at Schlock Mercenary, Howard Taylor has started a facinating conversation on the nature of Info-Wars. As Howard puts it:   Somebody (I forget who) tweeted that the Wikileaks fight right now is the first infowar in history. I disagree. I think we've fought numerous infowars in the last fifteen years. And that's really what I want to see discussed in the comments. We can argue right and wrong until the eCows come 127.0.0.1 but nobody is going to walk away convinced. I want to see a list of information-age conflicts that you feel qualify as "infowar." Me, I think the RIAA vs file-sharing qualifies. My buddy Rodney suggested RBLs vs Spammers (the spammers won that one.) Somebody pointed out that the Secret Service raid on Steve Jackson Games back in the 80's might qualify.

• What is the best currency API out there?

  - by YouBook

  I may be asking an odd question, but webmasters seem like a decent place to post this. I'm in the search for an accurate, easy API (such as using JSON or XML) so I can use my web application. I've been trying Google's secret API, but it's dependency isn't that good because of parsing the string (weird JSON format that PHP sometimes return incorrect data or truncates the string due to parsing error, but Google's API is fair but can be improved. So, all I'm asking is your current best currency API out there, I want to have them to include documented API so I can use it with PHP. Cheers.

• Juju bootstrap fails with "Temporary failure in name resolution" using Amazon AWS

  - by Will

  I have followed the instructions over at https://juju.ubuntu.com/docs/config-aws.html to try and setup myself with a juju environment. It all seemed to setup alright. SSH keys, Gererate config, repository, adding access id and secret keys to environments.yaml file. Although my key file from aws IAM management console was called credentials.csv rather than rootkey, I couldn't find that link described in the documentation. When I give the command juju bootstrap in the testing page. It fails giving me the error: juju bootstrap ERROR Get https://s3-us-west-1.amazonaws.com/juju-gobblygookmynukmbersinhere/provider-state: lookup s3-us-west-1.amazonaws.com: Temporary failure in name resolution (note I just replaced my numbers for this posting my actual terminal has my numbers in. This is my first attempt at any ec2 work so I have gone in and created new IAM profiles. What have I done wrong? Any help would be great. I think I'm in over my head!

• What reasons are there for not using a third party version control service?

  - by Earlz

  I've recently noticed a bit of a trend for my projects as of late. I use to run my own SVN server on my VPS, but recently the nail went in the coffin for that when I got my last project migrated from my server to a Mercurial repo on Bitbucket. What are some of the ramifications to this? (disregarding the change in version control systems) It seems like there has been a huge explosion in version control hosting, and companies like Bitbucket even offer private repos for free, and Github and other such services are extremely cheap now. Also, by using them you get the benefit of their infrastructure's speed and stability. What reasons are there these days to host your own version control? The only real reason I can think of is if your source code is super top secret.

• Broken Links in different browsers

  - by kdorival

  Hi I'm having problems with our website, http://www.accessiblehomehealthcare.com, which is a wordpress 2.7 (version). All of a sudden our RSS links broke on the right side, which has happened before and I fixed it within 5 mins. Now, when I fix it, it doesn't look right in different version of I.E. or Firefox, I have I.E. 8 and Firefox 3.6.15 and it looks good for the most part, but there are a few parts where the links are broken. One browser the links would look ok but go to another page and the links or logos would be broken. Certain parts of the website should be static(identical) to the other pages of the site, but if a link is broken on one page, its perfect on another page. I was wondering was there a secret code for wordpress to keep the sites compatible with all browser versions or is there a bigger issue???? Any help or suggestions will help???
