  • Getting into game/game engine programming

    - by Darkslash
    So I am interested in learning game programming, but I really have an interest in the lower level engineering in games. I have openGL experience, and I am really interested in learning more about implementing AI, Physics, etc. I have a computer science degree, so I really like getting into technical stuff. Many times when I ask about this sort of thing, I get a lot of "Use an engine", "Use Unity3d", "Why waste your time writing code that already exists", etc etc. My idea was to use simpler libraries such as SFML or XNA so that I could learn how to implement the more complex systems. The thing is, although I do want to write games, I want to learn things that using something like Unity simply doesnt teach you. My goal is not to make a current generation quality 3D game to sell, I just want to make some cool smaller games and learn all I can about the programming side of game development. Is this something that people just do not do anymore? It seems like everywhere I turn people are using Unity or UDK or GameMaker. I fully understand why you would use a tool like these, but I cant see how they would suit my purposes. So where does someone like myself turn? Am I trying to learn something that people just do not bother doing anymore? Is the innovation in this area gone and just all about gameplay now? Im sorry if this question seems silly, but I am genuinely interested in knowing more about this and meeting more people who are interested in this sort of thing.

  • Logging library for (c++) games

    - by Klaim
    I know a lot of logging libraries but didn't test a lot of them. (GoogleLog, Pantheios, the coming boost::log library...) In games, especially in remote multiplayer and multithreaded games, logging is vital to debugging, even if you remove all logs in the end. Let's say I'm making a PC game (not console) that needs logs (multiplayer and multithreaded and/or multiprocess) and I have good reasons for looking for a library for logging (like, I don't have time or I'm not confident in my ability to write one correctly for my case). Assuming that I need : performance ease of use (allow streaming or formating or something like that) reliable (don't leak or crash!) cross-platform (at least Windows, MacOSX, Linux/Ubuntu) Wich logging library would you recommand? Currently, I think that boost::log is the most flexible one (you can even log to remotely!), but have not good performance update: is for high performance, but isn't released yet. Pantheios is often cited but I don't have comparison points on performance and usage. I've used my own lib for a long time but I know it don't manage multithreading so it's a big problem, even if it's fast enough. Google Log seems interesting, I just need to test it but if you already have compared those libs and more, your advice might be of good use. Games are often performance demanding while complex to debug so it would be good to know logging libraries that, in our specific case, have clear advantages.

  • chromium-browser usus 99,99% IO disk

    - by lars
    My favorite browser: chromium is testing my patience. For some reason it sometimes uses 99,99% of I/O. (reading 2-3MB/s) Other processes (updatedb.mlocate, [kswapd0], clementine, compiz) show the same behavior. However this problem always starts and ends with chromium. To illustrate the impact on my system: when my disk starts to spin like crazy en the led burns continiously the system is so slow that it takes about two to five minuits to switch to tty6, log in and execute "killall chromiumbrowser && killall chromium" This is way faster than starting a new terminal in X, just starting a terminal seems to heavy for compiz under these circumstances. Waiting until its over takes more than 30 minuits, if it ends at all. The exact circumstances are difficult to replicate. Several tabs have to be open, usualy 8 or more. It seems that the chance to increases when more complex sites like gmail of plugins like flash are running. Opening several new tabs at omgubunt.co.uk has the best chance to replecate this isue. I have no idea where to start looking for a solution. Any help would be greatly apreciated ubuntu 12.10 | 2GB | 2x 1.66GHz Intel | 32bit | IBM Thinkpad R60e

  • Web Application: Combining View Layer Between PHP and Javascript-AJAX

    - by wlz
    I'm developing web application using PHP with CodeIgniter MVC framework with a huge real time client-side functionality needs. This is my first time to build large scale of client-side app. So I combine the PHP with a large scale of Javascript modules in one project. As you already know, MVC framework seperate application modules into Model-View-Controller. My concern is about View layer. I could be display the data on the DOM by PHP built-in script tag by load some data on the Controller. Otherwise I could use AJAX to pulled the data -- treat the Controller like a service only -- and display the them by Javascript. Here is some visualization I could put the data directly from Controller: <label>Username</label> <input type="text" id="username" value="<?=$userData['username'];?>"><br /> <label>Date of birth</label> <input type="text" id="dob" value="<?=$userData['dob'];?>"><br /> <label>Address</label> <input type="text" id="address" value="<?=$userData['address'];?>"> Or pull them using AJAX: $.ajax({ type: "POST", url: config.indexURL + "user", dataType: "json", success: function(data) { $('#username').val(data.username); $('#dateOfBirth').val(data.dob); $('#address').val(data.address); } }); So, which approach is better regarding my application has a complex client-side functionality? In the other hand, PHP-CI has a default mechanism to put the data directly from Controller, so why using AJAX?

  • Implement service layer in MVC

    - by Dan H
    We have a defined service layer hosted in WCF. We are now building a website that will need to use the services functionality. The website is being written in ASP.NET MVC 4 and I'm trying to decide how to reference the WCF service from the MVC app. It's a large complex website and it will be changing on a weekly basis. My first reaction is to abstract out the service references (About 7 services on this one WCF host) and create a service ref facade library with which the website interacts. But, I don't know exactly how to use the service facade in MVC. I'm starting to think the Models will be responsible for it because when the controller gets a model, that model should call the service (if needed) and return what the controller asked. I'm trying to avoid having the MVC app know details of the service references. So, I could have a model factory that creates whatever model the controllers need and they can use the service facade to accomplish it. Is this a good plan, or am I off track?

  • How to Clean Up and Fix Your Music Library with the MusicBrainz Database

    - by Erez Zukerman
    Over the years, some of us accumulate lots and lots of music files. Since these come from a variety of sources, they’re not always as neat as they could be. If your music library is in a bit of a jumble with tags missing, oddly named files and incomplete albums, read on to see how easy it is to make it neat once and for all. MusicBrainz is an online database that uses audio “fingerprints” to identify music tracks even when they’re incorrectly labelled. We’ll be using this database through a free client called Picard, available for Windows, Mac OS X and Linux. So first thing, head on over to Picard’s download page and get the installer. If you use Linux, you can install Picard using your package manager. Once you finish going through the installer, run Picard. Your firewall might pop up an alert telling you Picard is trying to access the Internet; you should agree to let Picard through. You will now see the main Picard interface.

  • Calculate the Intersection of Two Volumes

    - by igrad
    If you've ever played The Swapper, you'll have a good idea of what I'm asking about. I need to check for, and isolate, areas of a rectangle that may intersect with either a circle or another rectangle. These selected areas will receive special properties, and the areas will be non-static, since the intersecting shapes themselves will also be dynamic. My first thought was to use raycasting detection, though I've only seen that in use with circles, or even ellipses. I'm curious if there's a method of using raycasting with a more rectangular approach, or if there's a totally different method already in use to accomplish this task. I would like something more exact than checking in large chunks, and since I'm using SDL2 with a logical renderer size of 1920x1080, checking if each pixel is intersecting is out of the question, as it would slow things down past a playable speed. I already have a multi-shape collision function-template in place, and I could use that, though it only checks if sides or corners are intersecting; it does not compute the overlapping area, or even find the circle's secant line, though I can't imagine it would be overly complex to implement. TL;DR: I need to find and isolate areas of a rectangle that may intersect with a circle or another rectangle without checking every single pixel on-screen.

  • How far to go with Domain Driven Design?

    - by synti
    I've read a little about domain driven design and the usage of a rich domain model, as described by Martin Fowler, and I've decided to put it in practice in a personal project, instead of using transaction scripts. Everything went fine until UI implementation started. The thing is some views will use rich components that are backed up by unusual models and, thus, I must transform the domain model into what is used by those components. And that transformation is specially "complex" in the view-to-domain portion, up to the point that some business logic is involved. Wich brings me to the questioning: where should I do these adaptations? So far I've got the following conclusions: Doing it in the presentation layer is good because, well, if that layer imposes restrictions in it's model, then it should be the one to handle them. But it's bad because there'll be some business leakage. If I do it on the services objects (controllers, actions, whatever), then it'd be good because there won't be any change to the domain API just because of presentation layer, but it's bad because then I'd have transaction scripts, wich is not the intended design. Finally, if I do it on the domain model, there'd be no leakage of business logic at all. But in the future I could expect an explosion of the API into a series of methods designed just to handle that view-model <- domain-model adaptation. I hope I could make myself clear on this.

  • Is this kind of design - a class for Operations On Object - correct?

    - by Mithir
    In our system we have many complex operations which involve many validations and DB activities. One of the main Business functionality could have been designed better. In short, there were no separation of layers, and the code would only work from the scenario in which it was first designed at, and now there were more scenarios (like requests from an API or from other devices) So I had to redesign. I found myself moving all the DB code to objects which acts like Business to DB objects, and I've put all the business logic in an Operator kind of a class, which I've implemented like this: First, I created an object which will hold all the information needed for the operation let's call it InformationObject. Then I created an OperatorObject which will take the InformationObject as a parameter and act on it. The OperatorObject should activate different objects and validate or check for existence or any scenario in which the business logic is compromised and then make the operation according to the information on the InformationObject. So my question is - Is this kind of implementation correct? PS, this Operator only works on a single Business-wise Operation.

  • Server side C# MVC with AngularJS

    - by Ryan Langton
    I like using .NET MVC and have used it quite a bit in the past. I have also built SPA's using AngularJS with no page loads other than the initial one. I think I want to use a blend of the two in many cases. Set up the application initially using .NET MVC and set up routing server side. Then set up each page as a mini-SPA. These pages can be quite complex with a lot of client side functionality. My confusion comes in how to handle the model-view binding using both .NET MVC and the AngularJS scope. Do I avoid the use of razor Html helpers? The Html helpers create the markup behind the scene so it could get messy trying to add angularjs tags using the helpers. So how to add ng-model for example to @Html.TextBoxFor(x = x.Name). Also ng-repeat wouldn't work because I'm not loading my model into the scope, right? I'd still want to use a c# foreach loop? Where do I draw the lines of separation? Has anyone gotten .NET MVC and AngularJS to play nicely together and what are your architectural suggestions to do so?

  • Visual WebGui helps Dawsons put its Windows Forms HR system on the web

    - by Webgui
    Dawsons needed to upgrade their existing Windows Forms LAN human resources system to allow better and flexible access to the ever increasing data size as labor hire clients are demanding easy access to copies of tickets and licenses and etc. The company has some 30,000 applicants on file, but access to this data has been complex and limited with the current system. Therefore the IT department was asked to find a possible solutions that would allow creating a web based application while utilizing as much of the existing Windows Forms code as possible. Visual WebGui was found to be highly regarded in many frameworks comparisons so the team decided to give Visual WebGui a try. It didn’t take long for them to recognize that the Visual WebGui controls appear and react over the web the same as desktop controls. This and the fact that most of the code was directly ported which saved Dawsons hundreds of development hours are what make Visual WebGui so unique and productive. “My first impression of Visual WebGui was perhaps disbelief. Not being a seasoned Web programmer, I initially found it hard to accept so much functionality from a web based application. Also, the speed is exceptional” said John Sainsbury, Financial Controller of the Dawsons Group who added “Since working with Visual WebGui, I have showcased parts of the application to our major clients, some of whom use SAP portals, and they are amazed.” The result was so satisfying that the company is now looking to produce a mobile version for accessing the labor pool on the go. “By removing the barriers of the local network, Visual WebGui has changed how we can do business” said Lloyd Everist, General Manager Dawsons Group.

  • Strategy for restoring state via URL in web apps

    - by JW01
    This is a question about modern web apps, where a single page is loaded, and all subsequent navigation is done by XHR calls and modifying the DOM. We can use libraries that manipulate the hash string, which let us navigate by URL and support the back/forward buttons. But to use those libraries, we need to be able to move the UI from any one state to any other. Is there a good strategy for moving between UI states, that also allows them to be restored from scratch when you load a new URL? In a complex app, you might have a lot of different states. You don't want to reload the entire UI each time you change states. But you also don't want to require separate methods for moving from every state to each every state. Typically we need to: Restore a state from scratch, when you enter a new URL or hit Reload. Move from one state to another, when you use the Back/Forward buttons. Move from one state to another, when you perform an action within your app (like clicking a link). Move to certain states that shouldn't be added to the history, like ones that appear after form submissions. Move to some states that are built on the previous state, like a drill-down list. When you perform actions within your app, there's the additional question of which comes first: Do you change the URL, listen for the URL change, and change your state in response to it? Or do you change your state, then change the URL, but don't do anything in response? Does anyone have some experience to share on this topic?

  • Implement Budget Allocation in DAX for Power Pivot and Tabular #powerpivot #tabular #ssas #dax

    - by Marco Russo (SQLBI)
    Comparing sales and budget, or costs and budget, is a very common operation. However, it is often the case that you have different granularities for different tables containing budget and the data to compare with. There are two ways to do that: you can limit the comparison to the granularity that is common to the two tables, or you can allocate the budget where it’s not defined. For example, if you have a budget defined by quarter and category, you might want to allocate it by month and product. In this way, you will do the comparison as you had a more granular definition of the budget, without actually having to do the manual job of allocating data (usually in an Excel worksheet!). If you want to do budget allocation in DAX, you can use the Budget Patterns we published on DAX Patterns. If you come from and MDX/OLAP background, at first you might find it hard to solve the problem of not having attribute hierarchies that helps you in propagating the budget values to lower hierarchical levels. However, I think that once you get used to DAX, you will find the behavior very predictable and easy to “debug” also for more complex allocation formula. You just have to be careful in writing the DAX formula, but probably the pattern we wrote should help you designing the right data model, without creating physical relationships to the budget table! This pattern is also based on the Handling Different Granularities scenario I discussed a couple of weeks ago.

  • Can the csv format be defined by a regex?

    - by Spencer Rathbun
    A colleague and I have recently argued over whether a pure regex is capable of fully encapsulating the csv format, such that it is capable of parsing all files with any given escape char, quote char, and separator char. The regex need not be capable of changing these chars after creation, but it must not fail on any other edge case. I have argued that this is impossible for just a tokenizer. The only regex that might be able to do this is a very complex PCRE style that moves beyond just tokenizing. I am looking for something along the lines of: ... the csv format is a context free grammar and as such, it is impossible to parse with regex alone ... Or am I wrong? Is it possible to parse csv with just a POSIX regex? For example, if both the escape char and the quote char are ", then these two lines are valid csv: """this is a test.""","" "and he said,""What will be, will be."", to which I replied, ""Surely not!""","moving on to the next field here..."

  • Pub banter - content strategy at the ballot box?

    - by Roger Hart
    Last night, I was challenged to explain (and defend) content strategy. Three sheets to the wind after a pub quiz, this is no simple task, but I hope I acquitted myself passably. I say "hope" because there was a really interesting question I couldn't answer to my own satisfaction. I wonder if any of you folks out there in the ethereal internet hive-mind can help me out? A friend - a rather concrete thinker who mathematically models complex biological systems for a living - pointed out that my examples were largely routed in business-to-business web sales and support. He challenged me with: Say you've got a political website, so your goal is to have somebody read it and vote for you - how do you measure the effectiveness of that content? Well, you would. umm. Oh dear. I guess what we're talking about here, to yank it back to my present comfort zone, is a sales process where your point of conversion is off the site. The political example is perhaps a little below the belt, since what you can and can't do, and what data you can and can't collect is so restricted. You can't throw up a "How did you hear about this election?" questionnaire in the polling booth. Exit polls don't pull in your browsing history and site session information. Not everyone fatuously tweets and geo-tags each moment of their lives. Oh, and folks lie. The business example might be easier to attack. You could have, say, a site for a farm shop that only did over the counter sales. Either way, it's tricky. I fell back on some of the work I've done usability testing and benchmarking documentation, and suggested similar, quick and dirty, small sample qualitative UX trials. I'm not wholly sure that was right. Any thoughts? How might we measure and curate for this kind of discontinuous conversion?

  • Character progression through leveling, skills or items?

    - by Anton
    I'm working on a design for an RPG game, and I'm having some doubts about the skill and level system. I'm going for a more casual, explorative gaming experience and so thought about lowering the game complexity by simplifying character progression. But I'm having trouble deciding between the following: Progression through leveling, no complex skill progression, leveling increases base stats. Progression through skills, no leveling or base stat changes, skills progress through usage. Progression through items, more focus on stat-changing items, items confer skills, no leveling. However, I'm uncertain what the effects on gameplay might be in the end. So, my question is this: What would be the effects of choosing one of the above alternatives over the others? (Particularly with regards to the style and feel of the gameplay) My take on it is that the first sacrifices more frequent rewards and customization in favor of a simpler gameplay; the second sacrifices explicit customization and player control in favor of more frequent rewards and a somewhat simpler gameplay; while the third sacrifices inventory simplicity and a player metric in favor of player control, customization and progression simplicity. Addendum: I'm not really limiting myself to the above three, they are just the ones I liked most and am primarily interested in.

That is why in the past quarter (Q1) we put a great effort and get all the scenarios and users reports that we had so far and made this control as stable as possible. Now post Q1 we added some small, but important new features to the control. Here they are: Option to get the changed value when the focus of the control is lost. Before this change each user stroke causes the ValueChanged and ValueChanging events to be raised. Now you have to option to get these events on lost focus.

  • How to make game sessions like "with friends" games?

    - by Miguel lugo
    I want to make a game like "words with friends" or "chess with friends" or "Draw Something" or any of the other online multiplayer type games that are based around friends having game sessions with each other. I have made one app before that had no online features so I know the basics of objective-C and xCode. I looked up facebook connect so I know how to make friends find other friends to play with through Facebook. Just not how to make the gaming session. I only need my game to send a small array (or XML if it's better) of strings and integers from one iPhone to the other as each iPhone takes a turn. I'm NOT sending some complex video or anything like in "Draw Something." I was hoping someone could point me in the right direction (whether link to website or book or just a general idea) for how to do gaming sessions between two iPhones. I read this tutorial http://www.raywenderlich.com/3932/how-to-create-a-socket-based-iphone-app-and-server but it seems to be more about having two iPhones communicate over a server on a laptop or through the same wifi, not how to have iPhones game together over any Internet connection like in "with friends" games. I've tried to research this in other places but I'm never quite sure if what the articles I find are talking about is related to what I want or not. Someone please just point me in the right direction or give me a general outline of what to do. I will look up the specifics on my own once I know what to look for. Thank you.

  • Hiding the Flash Message After a Time Delay

    - by Madhan ayyasamy
    Hi Friends,The flash hash is a great way to provide feedback to your users.Here is a quick tip for hiding the flash message after a period of time if you don’t want to leave it lingering around.First, add this line to the head of your layout to ensure the prototype and script.aculo.us javascript libraries are loaded:Next, add the following to either your layout (recommended), your view templates or a partial depending on your needs. I usually add this to a partial and include the partial in my layouts. "flash", :id = flash_type % "text/javascript" do % setTimeout("new Effect.Fade('');", 10000); This will wrap the flash message in a div with class=‘flash’ and id=‘error’, ‘notice’ or ‘warn’ depending on the flash key specified.The value ‘10000’ is the time in milliseconds before the flash will disappear. In this case, 10 seconds.This function looks pretty good and little javascript stunts like this can help make your site feel more professional. It’s also worth bearing in mind though, not everybody can see well or read as quickly as others so this may not be suitable for every application.Update:As Mitchell has pointed out (see comments below), it may be better to set the flash_type as the div class rather than it’s id. If there is the possibility that you’ll be showing more than one flash message per page, setting the flash_type as the div id will result in your HTML/XHTML code becoming invalid because the unique intentifier will be used more than once per page.Here is a slightly more complex version of the method shown above that will hide all divs with class ‘flash’ after a time delay, achieving the same effect and also ensuring your code stays valid with more than one flash message! "flash #{flash_type}" % "text/javascript" do % setTimeout("$$('div.flash').each(function(flash){ flash.hide();})", 10000); In this example, the div id is not set at all. Instead, each flash div will have class “div” and also class of the type of flash message (“error”, “warning” etc.).Have a Great Day..:)

  • OWB/ODI Users: Last Chance to Submit and Vote On Sessions for OpenWorld 2010

    - by antonio romero
    Now is the last chance for OWB and ODI users to propose new ETL/DW/DI sessions for OpenWorld! Oracle OpenWorld 2010 "Suggest a Session" lets members of the Oracle Mix community submit and vote on papers/talks for OpenWorld. The most popular session proposals will be included in the conference program. One promising OWB-related topic has already been submitted: Case Study: Real-Time Data Warehousing and Fraud Detection with Oracle 11gR2 Dr. Holger Friedrich and consultants from sumIT AG in Switzerland built a real-time data warehouse and accompanying BI system for real-time online fraud detection with very limited resources and a short schedule. His presentation will cover: How sumIT AG efficiently loads complex data feeds in real time in Oracle 11gR2 using, among others, Advanced Queues and XML DB How they lowered costs and sped up development, by leveraging the DBs development features including Oracle Warehouse Builder How they delivered a production-ready solution in a few short months using only three part-time developers Come vote for this proposal, on Oracle Mix: https://mix.oracle.com/oow10/proposals/10566-case-study-real-time-data-warehousing-and-fraud-detection-with-oracle-11gr2  I have already invited members of the OWB/ODI Linkedin group (with over 1400 members) to come vote on topics like this one and propose their own. If enough of us vote on a few topics, we are sure to get some on the agenda!  And if you have your own topics, using the Suggest-a-Session instructions here: http://wiki.oracle.com/page/Oracle+OpenWorld+2010+Suggest-a-Session If you propose a topic, don't forget to come to Linkedin and promote it! I have already sent the members of the Linkedin group an email announcement about this, and I will send another in a week, with links to all topics submitted. Thanks, all!
