  • 2D graphics - why use spritesheets?

    - by Columbo
    I have seen many examples of how to render sprites from a spritesheet but I havent grasped why it is the most common way of dealing with sprites in 2d games. I have started out with 2d sprite rendering in the few demo applications I've made by dealing with each animation frame for any given sprite type as its own texture - and this collection of textures is stored in a dictionary. This seems to work for me, and suits my workflow pretty well, as I tend to make my animations as gif/mng files and then extract the frames to individual pngs. Is there a noticeable performance advantage to rendering from a single sheet rather than from individual textures? With modern hardware that is capable of drawing millions of polygons to the screen a hundred times a second, does it even matter for my 2d games which just deal with a few dozen 50x100px rectangles? The implementation details of loading a texture into graphics memory and displaying it in XNA seems pretty abstracted. All I know is that textures are bound to the graphics device when they are loaded, then during the game loop, the textures get rendered in batches. So it's not clear to me whether my choice affects performance. I suspect that there are some very good reasons most 2d game developers seem to be using them, I just don't understand why.

  • I want to build a Virtual Machine, are there any good references?

    - by Michael Stum
    I'm looking to build a Virtual Machine as a platform independent way to run some game code (essentially scripting). The Virtual Machines that I'm aware of in games are rather old: Infocom's Z-Machine, LucasArts' SCUMM, id Software's Quake 3. As a .net Developer, I'm familiar with the CLR and looked into the CIL Instructions to get an overview of what you actually implement on a VM Level (vs. the language level). I've also dabbled a bit in 6502 Assembler during the last year. The thing is, now that I want¹ to implement one, I need to dig a bit deeper. I know that there are stack based and register based VMs, but I don't really know which one is better at what and if there are more or hybrid approaches. I need to deal with memory management, decide which low level types are part of the VM and need to understand why stuff like ldstr works the way it does. My only reference book (apart from the Z-Machine stuff) is the CLI Annotated Standard, but I wonder if there is a better, more general/fundamental lecture for VMs? Basically something like the Dragon Book, but for VMs? I'm aware of Donald Knuth's Art of Computer Programming which uses a register-based VM, but I'm not sure how applicable that series still is, especially since it's still unfinished? Clarification: The goal is to build a specialized VM. For example, Infocom's Z-Machine contains OpCodes for setting the Background Color or playing a sound. So I need to figure out how much goes into the VM as OpCodes vs. the compiler that takes a script (language TBD) and generates the bytecode from it, but for that I need to understand what I'm really doing. ¹ I know, modern technology would allow me to just interpret a high level scripting language on the fly. But where is the fun in that? :) It's also a bit hard to google because Virtual Machines is nowadays often associated with VMWare-type OS Virtualization...

  • Geek Chess: Nixie Tubes as Board Pieces [Video]

    - by Jason Fitzpatrick
    We’ve seen some geeky chessboards in our day, but this board is a masterpiece of geekiness. Check out the video to see the Nixie tubes in action. Courtesy of a tinker named Tony, we find this delightfully analog and geeky chess set. He writes: This developed as a spinoff from the hardware and controllers I’m designing for a range of nixie clocks and watches as a ‘simple’ project that wouldn’t need much software to complete it. All visible parts are made from materials contemporary with Nixie technology and no modern plastics or resins are used anywhere in its’ consruction (other than the electronic components and PCBs). The board and pieces are machined from phenolic resin laminate and assembled using brass fittings. The brown base pieces have been filled and wiped with gold and silver engravers wax, giving a ‘worn gilding’ appearance. The displays are ex-Soviet Nixie gas display tubes, manufactured in the early 1980s.

  • Collocation in Code

    - by Dan McGrath
    Quite some time ago I remember reading an article from 'Joel on Software' that mentioned collocation of information in code was important. By collocation, I mean that relevant information about the code is present when the code is. I'm currently writing an article that has a small bit in it about collocation so I went searching for sources and found the quote in the article 'Making Wrong Code Look Wrong' In order to make code really, really robust, when you code-review it, you need to have coding conventions that allow collocation. In other words, the more information about what code is doing is located right in front of your eyes, the better a job you’ll do at finding the mistakes. When you have code that says For me, collocation isn't just about the code itself, but the tool used to view the code. If it can help with the 'collocation factor' (term coined by me?) I believe it can help with the programmers productivity. Take for example the modern IDEs that show you the variables type by hovering over it. Are their any other articles written about collocation in code and/or are their other terms that this is known by?

  • Tessellating to a curve?

    - by Avi
    I'm creating a game engine, and I'm trying to define a 3D model format I want to use. I haven't come across a format that quite does what I want. My game engine assumes a shader model 5+ environment. By the time I'm finished with it, that won't be a very unreasonable requirement. Because it assumes such a modern environment, I'm going to try and exploit tessellation. The most popular way, it seems, to procedurally increase geometry through tessellation is to tessellate to a height map. This works for a lot of things, but has limitations in that height maps still use up VRAM and also only have finite scalability. So I want to be able to use curves to define what a mesh should tessellate to. The thing is, I have no idea what definition of curves I should use, how I should store it, and how I should tessellate to it. Do I use NURBS curves? Bezier? Hermite? And once I figure that out, is there an algorithm to determine how the tessellation shader should produce and move vertices to match the curve as closely as possible? Is the infinite scalability and lower memory usage when compared to height maps worth the added computational complexity? I'm sorry I'm kind if ignorant as to these matters. I just don't know where to start.

  • Acceptable sound quality: stereo needed for an Android game?

    - by Thomas Calc
    I have various simple short sound effects (damage sound, dying sound, thunderbolt, fanfare, breaking) for a game that is developed for Android currently. I use OGG files: 96kbps VBR, 44.1KHz, 2 channels (that means stereo, right?). I read the other stackexchange topics about "acceptable sound quality", but they're too general, address too many things. My experience is that even with 80kbps, my effects sound OK. But I tested it on a limited number of Android devices (including a Sony Ericsson Xperia Neo and a HTC Desire HD). My questions: For mobile phones and tablets, generally, what parameters are recommended? Won't my 80kbps sounds be bad on a newer device (such as a modern tablet)? I don't hear any difference between stereo and mono (2 channels vs. 1 channel, right?), is there any noticeable difference at all for mobile phones / tablets? (in terms of the player experience) May it worth it at all? I assume that stereo sounds take much more in memory (when they're decoded to PCM), despite of the fact that the compressed OGG size is practically the same. Reacting to Roy T.'s great comment: Actually, I couldn't measure the PCM size (Android decodes OGG internally), but I thought that stereo will take more space than mono when uncompressed After throwing out one of the WAV channels in Audacity, and re-exporting it: The new WAV file size is half than before The OGG file size is practically the same as before The sound effects and game music was recorded by my friend who is an experienced hobby musician/composer, but he knows little about computers & software so he just gave me some high-quality WAV files generated via his hardware.These were stereo, but if I check them in Audacity, both channels appear to be exactly the same.Can I consider them the same (= moving to mono), or might there be some unnoticeable differences to the human eye?

  • Checking All Checkboxes in a GridView Using jQuery

    In May 2006 I wrote two articles that showed how to add a column of checkboxes to a GridView and offer the ability for users to check (or uncheck) all checkboxes in the column with a single click of the mouse. The first article, Checking All CheckBoxes in a GridView, showed how to add "Check All" and "Uncheck All" buttons to the page above the GridView that, when clicked, checked or unchecked all of the checkboxes. The second article, Checking All CheckBoxes in a GridView Using Client-Side Script and a Check All CheckBox, detailed how to add a checkbox to the checkbox column in the grid's header row that would check or uncheck all checkboxes in the column. Both articles showed how to implement such functionality on the client-side, thereby removing the need for a postback. The JavaScript presented in these two previous articles still works, but the techniques used are a bit antiquated and hamfisted given the advances made in JavaScript programming over the past few years. For instance, the script presented in the previous articles uses server-side code in the GridView's DataBound event handler to assign a client-side onclick event handler to each checkbox. While this works, it violates the tenets of unobtrusive JavaScript, which is a design guideline for JavaScript programming that encourages a clean separation of functionality from presentation. (Ideally, event handlers for HTML elements are defined in script.) Also, the quantity of JavaScript used in the two previous articles is quite hefty compared to the amount of code that would be needed using modern JavaScript libraries like jQuery. This article presents updated JavaScript for checking (and unchecking) all checkboxes within a GridView. The two examples from the previous articles - checking/unchecking all checkboxes using a button and checking/unchecking all checkboxes using a checkbox in the header row - are reimplemented here using jQuery and unobtrusive JavaScript techniques.

  • DAO/Webservice Consumption in Web Application

    - by Gavin
    I am currently working on converting a "legacy" web-based (Coldfusion) application from single data source (MSSQL database) to multi-tier OOP. In my current system there is a read/write database with all the usual stuff and additional "read-only" databases that are exported daily/hourly from an Enterprise Resource Planning (ERP) system by SSIS jobs with business product/item and manufacturing/SCM planning data. The reason I have the opportunity and need to convert to multi-tier OOP is a newer more modern ERP system is being implemented business wide that will be a complete replacement. This newer ERP system offers several interfaces for third party applications like mine, from direct SQL access to either a dotNet web-service or a SOAP-like web-service. I have found several suitable frameworks I would be happy to use (Coldspring, FW/1) but I am not sure what design patterns apply to my data access object/component and how to manage the connection/session tokens, with this background, my question has the following three parts: Firstly I have concerns with moving from the relative safety of a SSIS job that protects me from downtime and speed of the ERP system to directly connecting with one of the web services which I note seem significantly slower than I expected (simple/small requests often take up to a whole second). Are there any design patterns I can investigate/use to cache/protect my data tier? It is my understanding data access objects (the component that connects directly with the web services and convert them into the data types I can then work with in my Domain Objects) should be singletons (and will act as an Adapter/Facade), am I correct? As part of the data access object I have to setup a connection by username/password (I could set up multiple users and/or connect multiple times with this) which responds with a session token that needs to be provided on every subsequent request. Do I do this once and share it across the whole application, do I setup a new "connection" for every user of my application and keep the token in their session scope (might quickly hit licensing limits), do I set the "connection" up per page request, or is there a design pattern I am missing that can manage multiple "connections" where a requests/access uses the first free "connection"? It is worth noting if the ERP system dies I will need to reset/invalidate all the connections and start from scratch, and depending on which web-service I use might need manually close the "connection/session"

  • Oracle in Romania - 1: Brand new office, "Greenest in Bucharest"

    - by Steve Walker
    The importance of Romania within Oracle's global operations was underlined the other day as a marvellous new office building was opened at Floreasca Park in Bucharest.  The importance of the new facility was further underlined by presence of Oracle President Safra Catz, who participated in the opening ceremony. Seen here opening the building alongside Oracle Romania country leader Sorin Mindrutescu, Safra Catz said, "Our presence in Bucharest is significant and the work our teams are doing here is hugely valuable to our company and to our customers and partners. Our expansion in Bucharest signals our success in the region and commitment to making a positive contribution to the Romanian economy." The office itself looks very impressive, as the photos above show.  But more importantly, it is a cutting edge "green" office building in Bucharest, offering modern, environmentally friendly solutions such as a geo-thermal pump for heating and cooling, eco-friendly and chemical free materials used in walls and floors, a complex shading system, a bio diversity garden, and water and electricity saving equipment throughout the building. Floreasca Park is styled "the greenest office building in Bucharest" and its environmental credentials are laid out in full in a comprehensive infographic. Finally, Oracle's commitment to its Romanian operation was recognised as the company is proud to have been voted the most desired employer in Romania in surveys conducted by Catalyst Solutions and Brainspotting Consultancy. So, here's to the success of the Romanian operation, an important part of Oracle's global business and further testament to the importance of EMEA's contribution to the company's success.

  • Internship in License Contract Management

    - by cristian.condurache(at)oracle.com
    Hi Everyone, My name is Luca. I am an intern in the License Contract Management team in Italy. I have studied Economics and Business in Pescara and finished my Master’s Degree in July 2009. After a short work experience near my home town I decided to look for a job in an International Company. I got in touch with Oracle in January 2010. I had a telephone interview and then a face-to-face interview. On a cold and grey morning, I arrived in Milan....my first impression was fantastic....a big modern building with wide TVs everywhere. I was a little nervous but very excited. I understood this could be a great opportunity... The interview went well and I started to work in March. After a training period I was quickly involved in the closing of the last quarter of the fiscal year - of which May is the last month at Oracle. Working as a License Contract Manager is a real challenge for a fresh graduate. It involves thoroughly understanding the Oracle Policies and Practices with regards to License Contracts. In my experience, especially in May, I learnt to work under high pressure, within time constrains, and to keep up with constant changes. In this period I also had the opportunity to be involved in different negotiations, being directly in contact with the customers. This helped me to develop my relational skills during complex transactions. Looking back at the nine months at Oracle I can say I have a better understanding of the IT world. It is a complex environment that changes continously, offering new challenges to learn from everytime. If you have any questions related to this article feel free to contact [email protected].

  • Data binding in web UI frameworks, what's the deal?

    - by c-smile
    I believe that most of modern Web frameworks that pretend to be MVC ones also has a notion of data binding in one form or another. Examples: AngularJS, EmberJS, KnockoutJS, etc. I am assuming that "data binding" is a declarative definition (oxymoron, no?) of live link between data (a.k.a. model) and its representation (a.k.a. view). With some transformers in between (a.k.a. controllers). I understand why declarativeness is kind of appealing but also understand that as usual it comes with the price. In particular: 1. Live binding is quite heavy, either with dirty watch (high CPU consumption) or with Object.observe() (high memory consumption with high CPU load in some scenarios). 2. There is a "frame" part in the framework word, means there are some boundaries/limits that can be hard to overcome if you need slightly more than it was designed for. Quite usual time split: 90% of features are made in 10% of project time. But 10% rest take 90% of project time. I suspect (a.k.a. educated guess) that those MVC things are not helping to implement more functionality in less time... If so their usage motivation is not quite clear. As an example: last week wanted to find virtual list idea/solution. Found one in vanilla JavaScript that is 120 LOC. Implementation of the same but in AngualrJS is about 420 LOC. Most of the code there seems like a fight with the framework itself... So is my question: what benefits that MVC stuff or data binding give us? Is it just a buzzword popular among project managers or they give us something useful. If later one then what exactly?

  • Examples of limitations in IT due to different bit length by design

    - by Alaudo
    I am teaching the course "Introduction in Programming" for the first-year students and would like to find interesting examples where the datatype size in bits, chosen by design, led to certain known restrictions or important values. Here are some examples: Due to the fact that the Bell teleprinter used 7-bit-code (later accepted as ASCII) until now have we often to encode attachments in electronic messages to contain only 7 bit data. Classical limitation of 32-bit address space leads to the 4Gb maximal RAM size available for 32-bit systems and 4Gb maximal file size in FAT32. Do you know some other interesting examples how the choice of the data type (and especially its binary length) influenced the modern IT world. Added after some discussion in comments: I am not going to teach how to overcome limitations. I just want them to know that 1 byte can hold the values from -127..0..+127 o 0..255, 2 bytes cover the range 0..65535 etc by proving examples they know from other sources, like the above-mentioned base64 encoding etc. We are just learning the basic datatypes and I am trying to find a good reference for "how large" these types are.

  • Are very short or abbreviated method/function names that don't use full words bad practice or a matter of style.

    - by Alb
    Is there nowadays any case for brevity over clarity with method names? Tonight I came across the Python method repr() which seems like a bad name for a method to me. It's not an English word. It apparently is an abbreviation of 'representation' and even if you can deduce that, it still doesn't tell you what the method does. A good method name is subjective to a certain degree, but I had assumed that modern best practices agreed that names should be at least full words and descriptive enough to reveal enough about the method that you would easily find one when looking for it. Method names made from words help let your code read like English. repr() seems to have no advantages as a name other than being short and IDE auto-complete makes this a non-issue. An additional reason given in an answer is that python names are brief so that you can do many things on one line. Surely the better way is to just extract the many things to their own function, and repeat until lines are not too long. Are these just a hangover from the unix way of doing things? Commands with names like ls, rm, ps and du (if you could call those names) were hard to find and hard to remember. I know that the everyday usage of commands such as these is different than methods in code so the matter of whether those are bad names is a different matter.

It also features significant performance improvements. The only directly-visible difference is that the optional "Script run time" timing report no longer includes the time to setup and run the compiler, so it's a pure benchmark of the time required to actually execute a script.VidCoder: 1.5.23 Beta: Added first translations for 1.5. Includes new languages Portuguese, Japanese, Chinese Simplified and Czech. Many of these translations are still incomplete: you can help out on Crowdin.

  • Creating a retro-style palette swapping effect in OpenGL

    - by Zack The Human
    I'm working on a Megaman-like game where I need to change the color of certain pixels at runtime. For reference: in Megaman when you change your selected weapon then main character's palette changes to reflect the selected weapon. Not all of the sprite's colors change, only certain ones do. This kind of effect was common and quite easy to do on the NES since the programmer had access to the palette and the logical mapping between pixels and palette indices. On modern hardware, though, this is a bit more challenging because the concept of palettes is not the same. All of my textures are 32-bit and do not use palettes. There are two ways I know of to achieve the effect I want, but I'm curious if there are better ways to achieve this effect easily. The two options I know of are: Use a shader and write some GLSL to perform the "palette swapping" behavior. If shaders are not available (say, because the graphics card doesn't support them) then it is possible to clone the "original" textures and generate different versions with the color changes pre-applied. Ideally I would like to use a shader since it seems straightforward and requires little additional work opposed to the duplicated-texture method. I worry that duplicating textures just to change a color in them is wasting VRAM -- should I not worry about that?

  • What is a good support knowledge base tool?

    - by Guillaume
    I have been searching for a tool to help my team organize its knowledge for resolving recurring support cases. I know this question will probably be closed, but I'll try my change anyway because I know that I can have some good answers about that. Context: our team is developing and supporting an huge applications (lots of different screens and workflow processes. We already have a good tool for managing our documentation, but we are struggling with support cases. Support action involve often quite a lot of manual steps to fix stuff and the knowledge for these actions is more 'oral transmission' than modern tools. We need an efficient way to store them in a knowledge base to be able to retrieve similar cases based on patterns (a stacktrace, an error message, a component name, a workflow step, ...) and ranked by similarity. Our wiki search is not very powerful when it come to this kind of search and the team members don't want to 'waste' time writing a report that will never be found... Do you know efficient knowledge base tool for this kind of use case ?

  • An unexpected pleasure from Windows 8

    - by eddraper
    This post is certainly on the more nuanced side of all the goodness that is Windows 8, but it’s about something that’s really changed my PC usage experience for the better. Besides being a geek and the enjoying all the techno-thrills and chills that go along with sitting in front of a keyboard all day, I really love the forest.  Trees have always been special to me.  The feeling of being in the forest with all the sounds and ambiance, the broken light, the fragrance of the air… it’s paradise to me. As I can’t get there often, due to work, and quite often the heat here in Texas, I’ve found something that can at least partially fill the gap…  When you install Windows 8, you’ll have an app called “Naturespace” from http://www.naturespace.com/ .  It boasts a number of predefined loops in what they call “holographic audio.”  They’re essentially high-tech 3D sound fields recorded in natural environments. After checking them out, I really liked the sound of the “Daybreak” selection: A great benefit is that you don’t have to be in Metro/Modern/Windows App Store mode, in order to keep the sound playing.  To start the day, I click on Daybreak, start it, then go back to the desktop and fire up VS, Chrome, etc. As I work and play, I’m surrounded by this delightful background ambiance which relaxes me and puts my mind at ease. Give it a try.  I think you’ll like it.  And no, you don’t need ear buds or headphones to get the benefit.

  • Customer Service Experience, Oracle e Cels insieme per innovare le strategie.

    - by Claudia Caramelli-Oracle
    Si è svolto oggi il workshop Oracle "Customer Service Experience. Strategie per progettare un Servizio eccellente e profittevole." che ha visto il contributo del gruppo di ricerca CELS (Research Group on Industrial Engineering, Logistics and Service Operations) e della sezione ASAP SMF dell’Università degli Studi di Bergamo. Giuditta Pezzotta (PhD - Cels) e Roberto Pinto (PhD - Cels) ci hanno presentato la Service Engineering Methodology (SEEM), innovativa piattaforma metodologica che permette di ottimizzare la creazione di valore sia per il cliente finale sia per l’azienda, partendo dalla progettazione del prodotto e arrivando alla progettazione della soluzione prodotto-servizio, e valutando la bontà del prodotto-servizio ipotizzato attraverso strumenti concettuali e di simulazione dei processi. Armando Janigro, CX Strategy Director EMEA - Oracle ha invece parlato di Modern Customer Service, ovvero di come adattarsi in modo agile e veloce alle mutevoli necessità dei clienti, ipotizzando l’adozione in chiave strategica di nuovi strumenti di differenziazione e di leadership come la Customer Experience (CX) e sfruttando le nuove dinamiche di relazione azienda-singolo consumatore per ottimizzare l’esperienza multicanale e per render più efficiente il Customer Service, creando ulteriore valore. A seguire è stata mostrata da PierLuigi Coli, Principal Sales Consultant - Oracle, una demo sui prodotti Service Cloud offerti da Oracle, a supporto di tutti i concetti raccontati nelle sessioni precedenti. Il workshop è stato un’occasione unica per definire i percorsi da intraprendere per sviluppare efficaci strategie di Customer Experience grazie ad approcci e metodologie innovative alla base di uno sviluppo sostenibile del business. Le slide proiettate sono disponibili su richiesta: scrivi a Claudia Caramelli per ogni informazione o chiarimento.
