• Suggestions for a Self-serv advertising service

  - by Mystere Man

  I am seeking a self-serv advertising service for my websites, but I have a few restrictions that seem to make what i'm looking for hard to find. Specifically, I want to place "advertise here" links on my pages and allow end-users to purchase advertising on that site, page, and location. These ads will not be part of a national network. Supports multi-tenancy - That is, I have a number of domains using the same "web application" but with customized content per domain. When a customer wants to advertise on a given domain, then the ads will only appear on that domain and on that page of the domain (even though the page name may be the same across multiple domains). Supports fixed ad prices, not just CPC. I need monthly and quarterly pricing regardless of performance. Integrates with OpenX and other ad networks, so that if there is no self-serv on a given zone, it will use national advertising or direct advertising. Shiny Ads has much of this, but i'm looking for alternatives, as their prices are a bit crazy (20%) and can only do PayPal.

• A few questions about how JavaScript works

  - by KayoticSully

  I originally posted on Stack Overflow and was told I might get some better answers here. I have been looking deeply into JavaScript lately to fully understand the language and have a few nagging questions that I can not seem to find answers to (Specifically dealing with Object Oriented programming. I know JavaScript is meant to be used in an OOP manner I just want to understand it for the sake of completeness). Assuming the following code: function TestObject() { this.fA = function() { // do stuff } this.fB = testB; function testB() { // do stuff } } TestObject.prototype = { fC : function { // do stuff } } What is the difference between functions fA and fB? Do they behave exactly the same in scope and potential ability? Is it just convention or is one way technically better or proper? If there is only ever going to be one instance of an object at any given time, would adding a function to the prototype such as fC even be worthwhile? Is there any benefit to doing so? Is the prototype only really useful when dealing with many instances of an object or inheritance? And what is technically the "proper" way to add methods to the prototype the way I have above or calling TestObject.prototype.functionName = function(){} every time? I am looking to keep my JavaScript code as clean and readable as possible but am also very interested in what the proper conventions for Objects are in the language. I come from a Java and PHP background and am trying to not make any assumptions about how JavaScript works since I know it is very different being prototype based. Also are there any definitive JavaScript style guides or documentation about how JavaScript operates at a low level? Thanks!

• So now Google has said no to old browsers when can the rest of us follow suit?

  - by Richard

  Google recently announced that they will no longer support older browsers on Aug 1st: http://www.bbc.co.uk/news/technology-13639875 http://gmailblog.blogspot.com/2011/06/our-plans-to-support-modern-browsers.html For this reason, soon Google Apps will only support modern browsers. Beginning August 1st, we’ll support the current and prior major release of Chrome, Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version is released, we’ll begin supporting the update and stop supporting the third-oldest version. There is nothing worse than looking at the patching of code that takes place to support older browsers. If we could all move towards a standards only web (I'm looking at you IE9) then surely we could spend more time programming good web apps and less trying to make them run equally on terrible non standards compliant older browsers. So when can the rest of us expect to be able to tell our clients that we no longer support older browsers? Because it seems that large corporates will continue to run older browsers and even if google chrome frame can be installed without admin privileges (it's coming soon, currently in beta) we can't expect all users to be motivated to do this. I appreciate any thoughts.

• NINTENDO, EDCON and ALLEGIS GROUP @ Oracle Open World 2012 Conference Session (CON9418): The Business Case for Oracle Exalogic: A Customer Perspective

  - by Sanjeev Sharma

   Are you looking to deliver breakthrough performance for packaged and custom  applications? For many front-office applications such as Oracle WebCenter Sites, Oracle Transportation Management, and Oracle’s ATG and Siebel product families,  improved  performance leads directly to greater revenue or cost savings from the business - a  compelling  proposition. For back-office applications, improved performance has tangible benefits  in terms of  footprint reductions. For all applications, Oracle Exalogic and Oracle Exadata provide an engineered solution that provides shorter time to value and lower operational costs.  Edcon is a leading clothing, footwear and textiles (CFT) retailing group in southern Africa trading through a range of retail formats. The Company has grown from opening it's first store in 1929, to ten retail brands trading in over 1000 stores in South Africa, Botswana, Namibia, Swaziland and Lesotho. Edcon's retail business has, through recent acquisitions, added top stationery and houseware brands as well as general merchandise to its CFT portfolio. Edcon was looking to consolidate their existing middleware components (Weblogic and Oracle SOA) and retail applications (Retek, Siebel and E-Business Suite) on a common platform and turned to Oracle Exalogic. With Oracle Exalogic, Edcon is able to derive significant HW CAPEX savings, improve response-time of core business applications and mitigate operating risk. Hear senior business leaders from Nintendo, Edcon and Allegis Group discuss how the business value of  leveraging Oracle Exalogic at the following conference session at Oracle Open World 2012: Session:  CON9418 - The Business Case for Oracle Exalogic: A Customer PerspectiveDate: Monday, 1 Oct, 2012Time: 1:45 pm - 2:45 pm (PST)Venue: Moscone South (306)

• The advantages & disadvantages to be had from using a Web Framework?

  - by JHarley1

  Hello, This question is focused on extracting the advantages and disadvantages of using Web based Frameworks: such as Cake PHP, Zend, jQuery, ASP.NET). This question is completely language agnostic. Let me start with the notion of "Standing on the shoulders of Giants". Advantages: Empowers Developers - by taking features that would have previously have taken 100's of lines of code and compressing them into one simple function call empowers developers to integrate more complex features into their Web Sites. Allow for Quicker development of applications - this is very relevant for people that need websites created in a very small window (has anyone any examples of this?) Lower Costs - allows programmers to pass cost savings onto the customer, a whole new range of customers generated that wanted a website but previously could not afford the higher development costs. Disadvantages: Lost Understanding - by relying on the features of a framework a developer is in danger of loosing understanding on how things work (underneath the hood). The configuration cliff - once you go further than the configuration of your framework your productivity drops right off, it can be difficult to implement features outside of a frameworks configuration. Developer tramlines - you (the developer) has to do things the way that the developer want you to do things. Security issues - giving people these tools to develop professional looking websites fast is a potential risk, people can quickly create professional looking websites for fraudulent companies. I wonder what people make of my points, and whether any body disagrees with them? Also if people have additional points I would be grateful. Many Thanks, J

• Need Help Hiring a Perfectionist Programmer [closed]

  - by Bryan Hadaway

  I understand my question may be in the gray area, but I'm not able to use the Meta to ask if this question is appropriate or not so I'll simply have to risk it. My project is complete in the sense that it's a fully functional, ready to go 1.0 version. However, that's not good enough for my standards. My expertise is in HTML/CSS, not jQuery and PHP. I'm looking for someone to refine every character of my code for quality, speed, security and compatibility. I want everything to be as bug free as possible for launch. So I need an expert programmer who's a perfectionist in their coding who cares about the quality of their work (not just making it work) to review and refine my code. I'm sure I can't outright post the project's details and hope for interested parties to contact me as that wouldn't be beneficial to the community so instead I'm looking for advice from programmers about where some of best places to hire quality programmers are and the best strategies to hire the right programmer. In other words, screening applicants off of craigslist isn't going to cut it for this project. Thanks

• Information about rendering, batches, the graphical card, performance etc. + XNA?

  - by Aidiakapi

  I know the title is a bit vague but it's hard to describe what I'm really looking for, but here goes. When it comes to CPU rendering, performance is mostly easy to estimate and straightforward, but when it comes to the GPU due to my lack of technical background information, I'm clueless. I'm using XNA so it'd be nice if theory could be related to that. So what I actually wanna know is, what happens when and where (CPU/GPU) when you do specific draw actions? What is a batch? What influence do effects, projections etc have? Is data persisted on the graphics card or is it transferred over every step? When there's talk about bandwidth, are you talking about a graphics card internal bandwidth, or the pipeline from CPU to GPU? Note: I'm not actually looking for information on how the drawing process happens, that's the GPU's business, I'm interested on all the overhead that precedes that. I'd like to understand what's going on when I do action X, to adapt my architectures and practices to that. Any articles (possibly with code examples), information, links, tutorials that give more insight in how to write better games are very much appreciated. Thanks :)

• Physics-perfect (or somewhere near) 3d sound engine

  - by passcod

  I'm new to game programming, although I have some years of experience in console/web development. My problem is not so much that I can't find what I'm looking for, it's just that I don't have the terminology to actually perform a successful search. I am looking for a physics engine which has great focus on sounds. In fact, I do not care at all for anything else. What I mean is better explained by an example: Suppose a 1st person type game. You are facing North, and someone somewhere around you throws a flute at you (nevermind the absurdity of the situation). The flute spins while it is on its way, making sounds through its holes. There is a wind of say, 5 knots South. I imagine a physics engine will be capable of calculating the trajectory of the flute, as well as the direction it takes after it hits. What I want is for the physics engine to calculate the precise sounds it will make, from any listener's perspective. Does any such engine exists? If there are several, which one would be best for the example above?

• How does a single programmer make a game?

  - by Mike

  I have always been a software developer, but lately I've been wanting to get into games. The only thing stopping me is the fact that I'm a programmer, not an artist. I've made some simple stuff, Tetris, 2D chess things like that but I can't do much art and that's really what holds me back. Now the problem is, I've yet to go to college so most commercial projects wouldn't accept me even to work for free and learn a bit especially with my lack of experience in games and any indie projects I've looked into really have an issue with responding to people interested, or actually completing (or starting really, most don't get past the ideas on paper) the project they want to do. I've looked around locally for artists, anyone who can do modeling, textures or animating or even anyone with some ability to make some more advanced 2D assets to get something like a side-scrolling RPG or something but haven't been able to find anyone. So how do you guys do it? Do I really just have to wait until I can go to college to see if I like working with games or is there some way I can get art (for free, anything I do is just going to be for fun so I don't want to have to sink money into it) and just start messing around on my own? Or am I just having bad luck and not looking in the right places for other people interested in having me help? I'm not looking for anything in particular, just something to fill some time with and see if I like making games. If not, well I'll go back to my software projects. I just have one more year of highschool and I'd like to try a few different areas before I go to college.

• Will an online degree get you a job that requires "CS or equivalent 4-year degree"? [on hold]

  - by qel

  I'm a nerdy slacker type who didn't get my life together till I was 30. I've had a real job for a couple years doing C#/SQL. I've gotten several raises, but I'm making less than most developers, and the atmosphere is ... not positive. Looking for a new job, I think my applications get thrown out because I don't have a degree. And I want to finish a Bachelor's just to feel like less of a loser. I have a lot of college credits from 1996-2003 and a low GPA, so I don't know if that's worth much. An online degree looks like a good option, but I just don't know what I should be looking at for online schools because they all look like fake degrees. If they had programs equivalent to a real Comp Sci degree, I don't think they would have weird sounding names like they do. University of Phoenix has a B.S./Information Technology-Software Engineering. DeVry has a B.S./Computer Engineering Technology program. But that's not CS, and most other things I see have even more fake-sounding names. Are these useless degrees? Some people say DeVry and UoP are acceptable, some people say they're a joke. I have enough experience now, though, that maybe all I'm missing is being able to check the box that I have a 4-year degree. Harvard Extension seems like a real degree, even if it isn't a real Harvard degree, but I'd have to live there at least 3 months, which kinda defeats the purpose of an online degree fitting around work.

• Do the benefits of Resin/Quercus outweigh the overhead?

  - by Craige

  Lately, I've been looking more and more into Resin + Quercus as a technology to develop an application of mine. The reason I started looking into it was that this application has high reporting needs, a lot of which cannot (or realistically, should not) be created in real-time. Java would offer a nice backend to queue and generate reports. Also, with Quercus I would be able to develop my data models in Hibernate, and use them "from PHP", thus effectively stretching these models across front and back-end. This same concept would also apply to any front/back-end common business logic, which could be developed in Java libraries. Now, the downside is that whichever front-end (PHP) MVC Framework I choose (my goal was Symfony 2), it is unlikely to work without some heavy modification, if it can work at all. Quercus is a pretty close implementation of PHP, and is supposed to be compatible with PHP5.3, so namespaces and closures SHOULDN'T be a problem, but when I tried to run an existing Symfony 1.4 app, I failed miserably. So, my question to you is, do you think the benefits of Resin + Quercus outweigh the overhead of using a not-so-perfect/stable implementation of PHP? If this were your application, and your goal was and end-product, rather than educational purposes, what would you decide?

• Advice and resources on collaborative environments

  - by Tjaart

  I need some advice on collaborative software environments. More specifically, I am looking for books and reference materials that can aid me in understanding team and code structures and the interactions thereof. In other words books, blogs or white papers explaining: Different strategies for structuring teams that share common code between each other but have distinct individual functions? To summarise my question I would like to know what would be a good source of knowledge if I were to set up teams in an organisation that shared code but each unit still remained autonomous. I have done some research on this subject and explored: code review tools, distributed VCS, continuous integration tools, Unit testing automation. The tough part about implementing these tools are to determine where a good place would be to start, which tools are low hanging fruit, which tools or methods provide higher success rates. If someone asks me about code quality reference I point them to Code Complete. I am looking for an equivalent guide on software team structures and tools to make this equation work better. I realise that this question is quite vague but it arose as "we need to share code between teams without breaking each others stuff and causing management headaches and reams of red tape" The answer is definitely not simple and requires changes on many levels, hence the question. If the question is too vague please vote to close or delete. I would accept any good starting point as an answer.

• What are some good tips for a developer trying to design a scalable MySQL database?

  - by CFL_Jeff

  As the question states, I am a developer, not a DBA. I have experience with designing good ER schemas and am fairly knowledgeable about normalization and good schema design. I have also worked with data warehouses that use dimensional modeling with fact tables and dim tables. However, all of the database-driven applications I've developed at previous jobs have been internal applications on the company's intranet, never receiving "real-world traffic". Furthermore, at previous jobs, I have always had a DBA or someone who knew much more than me about these things. At this new job I just started, I've been asked to develop a public-facing application with a MySQL backend and the data stored by this application is expected to grow very rapidly. Oh, and we don't have a DBA. Well, I guess I am the DBA. ;) As far as designing a database to be scalable, I don't even know where to start. Does anyone have any good tips or know of any good educational materials for a developer who has been sort of shoved into a DBA/database designer role and has been tasked with designing a scalable database to support an application like this? Have any other developers been through this sort of thing? What did you do to quickly become good at this role? I've found some good slides on the subject here but it's hard to glean details from slides. Wish I could've attended that guy's talk. I also found a good blog entry called 5 Ways to Boost MySQL Scalability which had some good information, though some of it was over my head. tl;dr I just want to make sure the database doesn't have to be completely redesigned when it scales up, and I'm looking for tips to get it right the first time. The answer I'm looking for is a "list of things every developer should know about making a scalable MySQL database so your application doesn't perform like crap when the data gets huge".

• Good practices when optimizing HTML5/Javascript Game Developement [closed]

  - by hustlerinc

  I'm just starting out as a game developer and have created a few crappy but playable clones of classic games like pong, and bomberman. Being self taught (bless the internet) I do this by just stuffing in code to make the games work. Now I feel the time has come to create something complete, for this I need to know how a game is structured. I've searched on the web but there isn't that much to be found. The only "high-level" language I know is javascript so reading a tutorial or article based on C++ doesn't help me that much. I'm looking for good resource's pedagogically covering the theory and possibly examples (in Javascript or pseudo code that is understandable for a beginner) of how the game pieces fit together. From the start screen to asset loading and running the game loop. I'm not looking for anything complicated like reading through a 4000 line source code. All I want to learn is where, how and when the main parts of every game should be called. If you know any good resources to share, or maybe even have an answer for me I would deeply appreciate it.

• Is C# development effectively inseparable from the IDE you use?

  - by Ghopper21

  I'm a Python programmer learning C# who is trying to stop worrying and just love C# for what it is, rather than constantly comparing it back to Python. I'm really get caught up on one point: the lack of explicitness about where things are defined, as detailed in this Stack Overflow question. In short: in C#, using foo doesn't tell you what names from foo are being made available, which is analogous to from foo import * in Python -- a form that is discouraged within Python coding culture for being implicit rather than the more explicit approach of from foo import bar. I was rather struck by the Stack Overflow answers to this point from C# programmers, which was that in practice this lack of explicitness doesn't really matter because in your IDE (presumably Visual Studio) you can just hover over a name and be told by the system where the name is coming from. E.g.: Now, in theory I realise this means when you're looking with a text editor, you can't tell where the types come from in C#... but in practice, I don't find that to be a problem. How often are you actually looking at code and can't use Visual Studio? This is revelatory to me. Many Python programmers prefer a text editor approach to coding, using something like Sublime Text 2 or vim, where it's all about the code, plus command line tools and direct access and manipulation of folders and files. The idea of being dependent on an IDE to understand code at such a basic level seems anathema. It seems C# culture is radically different on this point. And I wonder if I just need to accept and embrace that as part of my learning of C#. Which leads me to my question here: is C# development effectively inseparable from the IDE you use?

• Twinview broken on upgrade to ubuntu 10.10

  - by mapkyca

  I have been on 9.10 for over a year on the grounds that if it ain't broke, don't fix it. However, I had a spare weekend and figured it was probably about time... I performed an upgrade to 10.4, and everything seemed to proceed smoothly, so I took the plunge and went for 10.10. Disaster. My twinview Nvidia display which had been working perfectly is now broken. On boot everything seems fine, but when X starts and the second monitor springs into life the primary winks out and switches off - almost as if its been put into an unsupported display mode. The system seems to think there's a second monitor - the nvidia logo is split across the two screens, but it can't seem to start. Things I've tried: Swapping the monitors (one is older than the other, and its definitely the port not the actual monitor) Rolling back to an old Xorg conf from prior to the upgrade Installing a non-beta driver direct from Nvidia (this seems to start both monitors but then apparently stops boot and causes the second display to 'wink'. Twinview seems non-functional, both displays are mirrors) Disabling EDID Disabling twinview, logging in and attempting to use the Nvidia config to re-detect the monitors (second monitor is falsely detected and won't go higher than 1024x768. Selecting 'apply' causes one screen to go blank and the other to display garbage) googling for about 5 hours looking for similar problems, none of the offered solutions seemed to work I'm at a loss, and it is looking very much like I'm going to have to go through a time consuming reinstall to downgrade back to the working 10.4. Any thoughts?

• What are some best practices for minimizing code?

  - by CrystalBlue

  While maintaining the sites our development team has created, we have come across include files and plugins that have proven to be very useful to more then one part of our applications. Most of these modules have come with two different files, a normal source file and a min file. Seeing that the performance and speed of a page can be increased by minimizing the size of the file, we're looking into doing that to our pages as well. The problem that we run into is a lot of our normal pages (written in ASP classic) is a mix of HTML, ASP, Javascript, CSS, and include files. We have some pages that have their JS both in include files and in the page, depending on if the function is only really used in that page or if it's used in many other pages. For example, we have a common.js and an ajax.js file, both are used in a lot of pages, but not all of them. As well as having some functions in a page that doesn't really make sense to put into one master page. What I have seen a few other people do online is use one master JS file and place all of their javascript into that, minify it, gzip it, and only use that on their production server. Again, this would be great, but I don't know if that fully works for our purposes. What I'm looking for is some direction to go with on this. I'm in favor of taking all of our JS and putting it in one include file, and just having it included in every page that is hit. However, not every page we have needs every bit of JS. So would it be worth the compilation and minifying of the files into one master file and include it everywhere, or would it be better to minify all other files and still include them on a need-to-use basis?

• How do 2D physics engines solve the problem of resolving collisions along tiled walls/floors in non-grid-based worlds?

  - by ssb

  I've been working on implementing my SAT algorithm which has been coming along well, but I've found that I'm at a wall when it comes to its actual use. There are plenty of questions regarding this issue on this site, but most of them either have no clear, good answer or have a solution based on checking grid positions. To restate the problem that I and many others are having, if you have a tiled surface, like a wall or a floor, consisting of several smaller component rectangles, and you traverse along them with another rectangle with force being applied into that structure, there are cases where the object gets caught on a false collision on an edge that faces the inside of the shape. I have spent a lot of time thinking about how I could possibly solve this without having to resort to a grid-based system, and I realized that physics engines do this properly. What I want to know is how they do this. What do physics engines do beyond basic SAT that allows this kind of proper collision resolution in complex environments? I've been looking through the source code to Box2D trying to find out how they do it but it's not quite as easy as looking at a Collision() method. I think I'm not good enough at physics to know what they're doing mathematically and not good enough at programming to know what they're doing programmatically. This is what I aim to fix.

• Methods for getting static data from obj-c to Parse (database)

  - by Phil

  I'm starting out thinking out how best to code my latest game on iOS, and I want to use parse.com to store pretty much everything, so I can easily change things. What I'm not sure about is how to get static data into parse, or at least the best method. I've read about using NSMutableDictionary, pLists, JSON, XML files etc. Let's say for example in AS3 I could create a simple data object like so... static var playerData:Object = {position:{startX:200, startY:200}}; Stick it in a static class, and bingo I've got my static data to use how I see fit. Basically I'm looking for the best method to do the same thing in Obj-c, but the data is not to be stored directly in the iOS game, but to be sent to parse.com to be stored on their database there. The game (at least the distribution version) will only load data from the parse database, so however I'm getting the static data into parse I want to be able to remove it from being included in the eventual iOS file. So any ideas on the best methods to sort that? If I had longer on this project, it might be nice to use storyboards and create a simple game editor to send data to parse....actually maybe that's a good idea, it's just I'm new to obj-c and I'm looking for the most straightforward (see quickest) way to achieve things. Thanks for any advice.

• Will I be able to get programming interviews at good software companies with a non-CS degree?

  - by friend

  I'll be graduating in a year, but I'll have a degree in Economics. I'm pretty much done with my Economics coursework, and by the time next year comes around I will have devoted 1.5 years to learning CS. I will have almost finished the requirements to graduate with a degree in CS, but unfortunately my school requires a science series that would add another 6-9 months of study if I were to try and get the degree (not to mention a max unit cap). I have or will have taken: Objected Oriented Programming Discrete Math Data structures Calculus through multivariable (doubt this matters at all) Linear Algebra (same) Computer Organization Operating Systems Computational Statistics (many data mining projects in R) Parallel Programming Programming Languages Databases Algorithms Compilers Artificial Intelligence I've done well in the ones I've taken, and I hope to do well in the rest, but will that matter if I can't say to the HR people that I have a CS degree? I'd be happy to get an internship at first too, so should I just apply as if I'm an intern and not looking for fulltime, and then try and parlay that into something? Sidenote if you have time -- Is a computer networks or theory of computation class important? Would it be worth taking either of those in lieu of a class on my list? edit -- I know this isn't AskReddit or College Confidential; I know there will be some outrage at posting a question like this. I'm merely looking for insight into a situation that I've been struggling with, and I think this is the absolute best place to find an answer to this question. Thanks.

• Advanced TSQL training

  - by Dave Ballantyne

  Over the past few years, Ive had it on my to do list to write and deliver and full-scale SQLServer training course and not just an hour long bite size session at user groups and conferences.  To me, SQLServer development is not just knowing and remembering the syntax of commands.  Sometimes I semi-jest that i have “Written a merge statement without looking up the syntax”, but I know from my interactions on and off line that I am far from alone in this.  In any case we have an awesome tool in the internet which is great at looking things up. When developing SQL Server based solutions,  of more importance is knowing the internals of the engine.  SQL Server is a complex piece of software and we need to be able to understand to a fairly low level ( you can always dive deeper ) the choices that it makes and why it makes them in order to deliver performant, reliable, predictable and scalable systems to our customers and end-users.

• Windows Recovery from Grub messed up my computer?

  - by Hudson Worden

  Ok so I'm a noob when it comes to Operating Systems and I think I really messed up this time. So I have a laptop that dual boots Windows 7 and Linux Mint 11. I was trying to boot into Windows 7 but it would just have a black screen with a blinking cursor. So I turned off my computer and tried again. Still a black screen with a cursor. So I thought "well it must be broken somehow and I remembered seeing something like 'Windows Recovery' from the boot menu so I should try it." So when I turned on my computer a third time I selected 'Windows Recovery' (Something like that I can't remember exactly what it was called). After I had selected that I got a white Windows window that said in big red letters "ERROR". I turned off my computer again a turned it back on expecting the Grub menu to reappear. I was wrong. Instead I am greeted with error: no such partition grub rescue. Then I put in a live CD for ubuntu 11.04 and tried looking at my partitions using the disk manager. Looking at my partitions I notice that there isn't a Linux partition anymore and in its place is a unallocated space partition yet the Linux Swap partition is still there. My windows partition is still fine and I can access the files in it. If you understand what has happened, is there anyway I can get my files back? I don't care about reinstalling the OS again. I just want those files that are in the Linux Mint partition.

• Make a basic running sprite effect

  - by PhaDaPhunk

  I'm building my very first game with XNA and i'm trying to get my sprite to run. Everything is working fine for the first sprite. E.g : if I go right(D) my sprite is looking right , if I go left(A) my sprite is looking left and if I don't touch anything my sprite is the default one. Now what I want to do is if the sprite goes Right, i want to alternatively change sprites (left leg, right leg, left leg etc..) xCurrent is the current sprite drawn xRunRight is the first running Sprite and xRunRight1 is the one that have to exchange with xRunRight while running right. This is what I have now : protected override void Update(GameTime gameTime) { float timer = 0f; float interval = 50f; bool frame1 = false ; bool frame2 = false; bool running = false; KeyboardState FaKeyboard = Keyboard.GetState(); // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); if ((FaKeyboard.IsKeyUp(Keys.A)) || (FaKeyboard.IsKeyUp(Keys.D))) { xCurrent = xDefault; } if (FaKeyboard.IsKeyDown(Keys.D)) { timer += (float)gameTime.ElapsedGameTime.TotalMilliseconds; if (timer > interval) { if (frame1) { xCurrent = xRunRight; frame1 = false; } else { xCurrent = xRunRight1; frame1 = true; } } xPosition += xDeplacement; } Any ideas...? I've been stuck on this for a while.. Thanks in advance and let me know if you need any other part from the code.
