  • Best practices for using namespaces in C++.

    - by Dima
    I have read Uncle Bob's Clean Code a few months ago, and it has had a profound impact on the way I write code. Even if it seemed like he was repeating things that every programmer should know, putting them all together and putting them into practice does result in much cleaner code. In particular, I found breaking up large functions into many tiny functions, and breaking up large classes into many tiny classes to be incredibly useful. Now for the question. The book's examples are all in Java, while I have been working in C++ for the past several years. How would the ideas in Clean Code extend to the use of namespaces, which do not exist in Java? (Yes, I know about the Java packages, but it is not really the same.) Does it make sense to apply the idea of creating many tiny entities, each with a clearly define responsibility, to namespaces? Should a small group of related classes always be wrapped in a namespace? Is this the way to manage the complexity of having lots of tiny classes, or would the cost of managing lots of namespaces be prohibitive?

  • Agile development challenges

    - by Bob
    With Scrum / user story / agile development, how does one handle scheduling out-of-sync tasks that are part of a user story? We are a small gaming company working with a few remote consultants who do graphics and audio work. Typically, graphics work should be done at least a week (sometimes 2 weeks) in advance of the code so that it's ready for integration. However, since SCRUM is supposed to focus on user stories, how should I split the stories across iteration so that they still follow the user story model? Ideally, a user story should be completed by all the team members in the same iteration, I feel that splitting them in any way violates the core principle of user story driven development. Also, one front end developer can work at 2X pace of backend developers. However, that throws the scheduling out of sync as well because he is either constantly ahead of them or what we have done is to have him work on tasks that not specific to this iteration just to keep busy. Either way, it's the same issue as above, splitting up user story tasks. If someone can recommend an active Google agile development group that discusses these and other issues, that'll be great. Also, if you know of a free alternative to Pivotal Labs, let me know as well. I'm looking now at Agilo.

  • How to pick a great working team?

    - by Javierfdr
    I've just finished my master and I'm starting to dig into the laboral world, i.e. learning how programming teams and technology companies work in the real world. I'm starting to design the idea of my own service or product based on free software, and I will require a well coupled, enthusiast and fluid team to build and the idea. My problem is that I'm not sure which would be the best skills to ask for a programming team of 4-5 members. I have many friends and acquaintances, with whom I've worked during my studies. Must of those ones I have in mind are very capable and smart people, with a good logic and programming base, although some of them have some characteristics that I believe that could influtiate negatively in the group: lack of communication, fear to debate ideas, hard to give when debating, lack of structured programming (testing, good commenting, previous design and analysis). Some of them have this negative characteristics, but must of them have a lot of enthusiasm, nice working skills (from an individual point of view), and ability to see the whole picture. The question is: how to pick the best team for a large scale project, with a lot of programming? Which of these negative skills do you think are just too influential? Which can be softened with good leadership? Wich good skills are to be expected? And any other opinion about social and programming skills of a programming team.

  • System boots in console + login loop

    - by Imagicien
    I messed up my system while trying to fix permission problems for setting up a LAMP local server. I tried this solution: How to avoid using sudo when working in /var/www? without success. Then I saw this solution: Permissions issue: how can Apache access files in my Home directory? I understood that I had to change the permissions of my root directory (among others), so I executed: sudo chmod 710 / I also changed the user group on / to www-data. I also did these operations on /home. I'm pretty sure one of those commands broke something, because it's the last commands I executed, and after that, my system showed strange/broken behavior: Firefox stopped showing pages Some icons got replaced by an red X icon (meaning "Icon not found" I guess) Applications refused to launch (no reaction) After rebooting: I got a strange graphical message talking about not being able to mount something, asking me if I wanted to wait, and talking about /tmp (I forgot the message since I was in shock) My system now boots in console, and when I login, it flashes unsignificant stuff* before re-asking me to login. My important data is on Ubuntu One. I'd prefer not having to reinstall from scratch. Is there a way to regain access to my system? Thanks a lot for your help. *Looks like a terminal header with the name of the OS and other info. Doesn't seem important.

  • JSR Updates - Multiple JSRs migrate to latest JCP version

    - by Heather VanCura
    As part of the JCP.Next reform effort, many JSRs have migrated to the latest version of the JCP program in the last month.  These JSRs' Spec Leads and Expert Groups are contributing to the strides the JCP has been making to enable greater community transparency, participation and agility to the working of the JSR development through the JCP program. Any other JSR Spec Leads interested in migrating to the latest JCP version, now JCP 2.9, as of 13 November, incorporating the Merged Executive Committee (EC), see the Spec Lead Guide for instructions on migrating to the latest JCP version.  For JCP 2.8 JSRs, you are effectively already operating under JCP 2.9 since there are no longer two ECs.  This is the difference for JCP 2.8 JSRs migrating to JCP 2.9 -- a merged EC.  To make the migration official, just inform your Expert Group on a public channel and email your request to admin at jcp.org. JSR 310, Date and Time API, led by Stephen Colebourne and Michael Nascimento and Oracle (Roger Riggs)  JSR 349, Bean Valirdation 1.1, led by RedHat (Emmanuel Bernard) JSR 350, Java State Management, led by Oracle (Mitch Upton) JSR 339, JAX-RS 2.0: The Java API for RESTful Web Services, led by Oracle, (Santiago Pericas-Geertsen and Marek Potociar) JSR 347, Data Grids for the Java Platform, led by RedHat (Manik Surtani)

  • Where to find Oracle Training for BI & EPM Partners

    - by Mike.Hallett(at)Oracle-BI&EPM
    We run both “Live Virtual Training” (web-based classes) as well as “In Class Training” in most countries around Europe, Middle East and Africa. Some of these are subsidised for OPN partners, while others are available at a discount (usually 25%) to OPN partners via OU (Oracle University).  To see what is scheduled for in-depth hands-on implementation training for partners see:   Oracle Business Intelligence Enterprise Edition Plus Implementation Boot Camp For example, these are some of the OBI11g Boot-camps we currently have scheduled: 11 - 15 June 2012 Bucharest, Romania 21 - 23 August 2012 Johannesburg, South Africa 24 - 28 September 2012 Utrecht, Netherlands Oracle Essbase Implementation Boot Camp Oracle GoldenGate Implementation Boot Camp Hyperion Planning Boot Camp   Hyperion Financial Management Boot Camp   Oracle Business Intelligence Applications for ERP Boot Camp     You can also selectively filter search for courses via the Partner Events Calendar @ http://events.oracle.com/search/search?group=Events&keyword=OPN+Only   Otherwise, it is worth checking the Oracle Partner Enablement BLOG for any BI / EPM news, especially the sub-Blogs on the right for each country.   There is also a monthly Partner Enablement Update (PDF) to find out the latest partner training on Oracle's new products and new releases.

  • How should I show shared resources during a Shared Resource game in the Galaxy Editor?

    - by Mag Roader
    One of my favorite ways to play the original StarCraft was in a "Team" game. In this game type, multiple players on the same "team" would share control, resources, supply, and even the same starting location. It was like playing as 1 player, only 2 humans were controlling it. It was a lot of fun. I want to do something very similar in StarCraft 2, but I need to create a custom map in the Galaxy Editor to do it. I found the editor can quite easily emulate this behavior. There is a Trigger action "Set Alliance for Player Group" to "...treat each other as Ally With Shared Vision, Control, And Spending." To use this, I create units for only 1 of the players, and then set all players to be allied with each other in this way. All the other players get no units and no resources. This makes it so 1 player is the actual owner of all the units and everyone else is tagging along with full control. This nearly works! The problem is that if I am not the actual owning player, I can't actually see how many minerals/gas/supply the team has. This makes it pretty difficult to build stuff. What would be the best way to display to the other players how many Minerals/Gas/Supply the team has?

  • Solaris 11 Customer Maintenance Lifecycle

    - by user12244672
    Hi Folks, Welcome to my new blog, http://blogs.oracle.com/Solaris11Life , which is all about the Customer Maintenance Lifecycle for Image Packaging System (IPS) based Solaris releases, such as Solaris 11. It'll include policies, best practices, clarifications, and lots of other stuff which I hope you'll find useful as you get up to speed with Solaris 11 and IPS.   Let's start with a version of my Solaris 11 Customer Maintenance Lifecycle presentation which I gave at this year's Oracle Open World and at the recent Deutsche Oracle Anwendergruppe (DOAG - German Oracle Users Group) conference in Nürnberg. Some of you may be familiar with my Patch Corner blog, http://blogs.oracle.com/patch , which fulfilled a similar purpose for System V [five] Release 4 (SVR4) based Solaris releases, such as Solaris 10 and below. Since maintaining a Solaris 11 system is quite different to maintaining a Solaris 10 system, I thought it prudent to start this 2nd parallel blog for Solaris 11. Actually, I have an ulterior motive for starting this separate blog.  Since IPS is a single tier packaging architecture, it doesn't have any patches, only package updates.  I've therefore banned the word "patch" in Solaris 11 and introduced a swear box to which my colleagues must contribute a quarter [$0.25] every time they use the word "patch" in a public forum.  From their Oracle Open World presentations, John Fowler owes 50 cents, Liane Preza owes $1.25, and Bart Smaalders owes 75 cents.  Since I'm stinging my colleagues in what could be a lucrative enterprise, I couldn't very well discuss IPS best practices on a blog called "Patch Corner" with a URI of http://blogs.oracle.com/patch.  I simply couldn't afford all those contributions to the "patch" swear box. :) Feel free to let me know what topics you'd like covered - just post a comment in the comment box on the blog. Best Wishes, Gerry.

  • Tracking feature requests for small-scale components

    - by DXM
    I'm curious how other development teams (especially those that work in moderate to large development groups) track "future" features/wishlists for functionality for internally developed frameworks or components. I know the standard advice is that a development team should find one good tool for tracking bugs/features and use that for everything and I agree with that if the future requests are for the product itself. In my company we have an engineering department, which is broken up into multiple groups and within each there can be one to several agile teams. The bug tracking product we use has been "a leader since 1997" (their UI/usability seems to also be evaluated against that year even today) but my agile team or even group doesn't really control what is being used by the whole department. What we are looking to track is not necessarily product features but expansion/nice to have functionality for internal components that go into our product. So to name a few for example... framework/utility library on top of CppUnit which our developers share low-level IPC communications framework Common development SDK that myself and several other team leads started to help share some common code/tools at the department-wide level (this SDK is released as internal "product" to each of the groups). Is the standard practice to use the one bug tracking tool? Or would it make more sense to setup something more localized specifically for our needs and maintain it ourselves? It's also unclear how management will feel if developers start performing "IT" roles of maintaining software and servers. At the same time, right now, we use excel files, internal wiki and MS OneNote for this kind of stuff and that just doesn't feel right. (I'm afraid to ask for actual software recommendations, since that might make this question more localized or something. Also developers needs this way more than management, so it would be nice to find something either free or no more than the cost of a happy hour).

  • Update

    - by Jeff Certain
    This blog has been pretty quiet for a year now. There's a few reasons for that. Probably the biggest reason is that I view this as a space where I talk about .NET things. Or software development. While I've been doing the latter for the past year, I haven't been doing the former.Yes, I took a trip to the dark side. I started with Ning 11 months ago, in Palo Alto, CA. I had the chance to work with an incredibly talented group of software engineers... in PHP and Java.That was definitely an eye-opening experience, in terms of technology, process, and culture. It was also a pretty good example of how acquisitions can get interesting. I'll talk more about this, I'm sure.Last week, I started with a company called Dynamic Signal. I'm a "Back End Engineer" now. Also a very talented team of people, and I'm delighted to be working with them. We're a Microsoft shop. After a year away, I'm very happy to be back. Coming back to .NET is an easy transition, and one that has me being fairly productive straight out of the gate.(Some of you may have noticed, my last post was more than a year ago. Yes, it's safe to infer that I didn't get renewed as an MVP. Fair deal; I didn't do nearly as much this year as I have in the past. I'll be starting to speak again shortly, and hope to be re-awarded soon.)At any rate, now that I'm back in the .NET space, you can expect to hear more from me soon!

  • Executing NUnit Tests using the Visual Studio 2012 Test Runner

    - by David Paquette
    At a recent Visual Studio 2012 event at the Calgary .NET User Group, I was told that I could run my NUnit tests directly in the Visual Studio 2012 without any special plugins.  Naturally, I was very excited and I immediately tried running my NUnit tests. I was somewhat disappointed to see that the Test Runner did not discover any of my NUnit tests.  Apparently, you do still need to install an extension that supports NUnit.  Microsoft has completely re-written the Test Runner in Visual Studio 2012 and opened it up for anyone to write Test Adapters for any unit test framework (not just MSTest).  Once the correct test adapters are installed, everything works great.  Luckily, there are a good number of adapters already written. Here are some Test Adapters that you might find useful: NUnit Test Adapter – This one is still in beta, but tit does work with the official Visual Studio 2012 release xUnit.net Test Adapter Silverlight Unit Test Adapter Chutzpah Test Adapter Overall, I still prefer the unit test runner in ReSharper, but this is a great new feature for those who might not have a ReSharper license.

  • SSIS Denali as part of “Enterprise Information Management”

    - by jorg
    When watching the SQL PASS session “What’s Coming Next in SSIS?” of Steve Swartz, the Group Program Manager for the SSIS team, an interesting question came up: Why is SSIS thought of to be BI, when we use it so frequently for other sorts of data problems? The answer of Steve was that he breaks the world of data work into three parts: Process of inputs BI   Enterprise Information Management All the work you have to do when you have a lot of data to make it useful and clean and get it to the right place. This covers master data management, data quality work, data integration and lineage analysis to keep track of where the data came from. All of these are part of Enterprise Information Management. Next, Steve told Microsoft is developing SSIS as part of a large push in all of these areas in the next release of SQL. So SSIS will be, next to a BI tool, part of Enterprise Information Management in the next release of SQL Server. I'm interested in the different ways people use SSIS, I've basically used it for ETL, data migrations and processing inputs. In which ways did you use SSIS?

  • Perth's ADF Community Event now an open invite

    - by Chris Muir
    Yesterday saw the next ADF Community Event in Perth, and as promised we grew from 15 to 25 attendees (which is going to cause a bit of a problem soon if we keep growing as we're going to run out of powerpoints for laptops). This bimonthly enjoyed presentations from Matthew Carrigy from the Dept of Finance WA on the ADF UI Shell, a small presentation from me about how Fusion Apps uses ADF, and a hands on based on programatically extending ADF BC to call external web services.  For Matt, his first presentation to a user group, with two live demos, all kudos to him for making it look smooth (for the record I hate live demos, I always break something) - thank you Matt! We've already lined up our speakers for the next event in November, and will be inviting yet more customers to this event.  However the event will now move to an open invite, so if you'd like your staff to attend please let me know by emailing chris DOT muir AT oracle DOT com. Alternatively I've had a fair few requests now for an "Intro to ADF" 1 day session so I'll consider this soon.  Certainly if you're interested let me know as this will help organize the event earlier rather than later.

  • Broad topics needed for teaching game development

    - by livingtech
    I am going to be doing a presentation on game development to an iPhone user group in the near(ish) future. My audience are iPhone developers, but not necessarily very experienced ones, and this is meant to be an introduction. My question is, what broad topics are needed to understand game development? I acknowledge that this is fairly subjective, but I really am hoping for a comprehensive list of high-level topics that apply to a broad enough swath of games that anyone interested in the topic SHOULD know about them. I would be ecstatic with some pointers to any resources that attempt to make a list such as this this. (I have looked, but my google-fu is failing me tonight.) Here's what I have so far: The Game Loop a sub-note about event driven games 2D Animation sprites/texture maps 3D Animation importance of frameworks modeling software Particles and particle effects hit detection AI Obviously I will not be covering all these topics with any depth, more like simply defining them so that after my talk, the audience will (hopefully) be able to wrap their heads around how any given game might be developed. What am I missing?

  • mdadm: brakes boot due to "is not ready yet or not present" error

    - by BarsMonster
    This is so damn frustrating :-| I've spent like 20 hours on this nice error, and seems like dozens of people over Internet too, and no clear solution yet. I have non-system RAID-5 of 5 disks, and it's fine. But during boot up it says that "/dev/md0 is not ready yet or not present" and asks to press 'S'. Very nice for Ubuntu Server - I have to bring monitor and keyboard to go next. After this system boots and it's all fine. md0 device works, /proc/mdstat is fine. When I do mount -a - it mounts this array without errors and works fine. As a dumb and shameful workaround I added noauto in /etc/fstab, and did mounting in /etc/rc.local - it works fine then. Any hints how to make it work properly? fstab: UUID=3588dfed-47ae-4c32-9855-2d69df713b86 /var/bigfatdisk ext4 noauto,noatime,data=writeback,barrier=0,nobh,commit=5 0 0 mdadm config: It is autogenerated: # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired.

  • How do I find a programming internship / practice?

    - by user828584
    I'm taking the SAT soon, and quickly heading toward the chaos of figuring out which college's I will be able to attend, and how on Earth I'll be able to afford it. I would like to be able to gain some experience in programming or web development, but I don't know where to look. I've been trying my best to learn over the past year, and have been doing alright in C# and the web languages (HTML, PHP, CSS, javascript). I have no idea where to look though. I've asked similar questions and rummaged through old questions on here, and they all say nothing specifically. The main two points are always "Contribute to open source projects" and "Find a company and ask to be a part of it." I don't know how to find either of the two. I've looked online at github and source forge, and the like, but all the projects are already so progressed and I just don't have the experience needed to bring myself up to speed with their code. I don't have much experience in code management, and I don't know how to get it. I would be ecstatic to be able to start a project with a group of more experienced members, but, like I said, I have no clue how to find these people.

  • Why Wouldn't Root Be Able to Change a Zone's IP Address in Oracle Solaris 11?

    - by rickramsey
    You might assume that if you have root access to an Oracle Solaris zone, you'd be able to change the root's IP address. If so, you'd proceed along these lines ... First, you'd log in: root@global_zone:~# zlogin user-zone Then you'd remove the IP interface: root@user-zone:~# ipadm delete-ip vnic0 Next, you'd create a new IP interface: root@user-zone:~# ipadm create-ip vnic0 Then you'd assign the IP interface a new IP address (10.0.0.10): root@user-zone:~# ipadm create-addr -a local=10.0.0.10/24 vnic0/v4 ipadm: cannot create address: Permission denied Why would that happen? Here are some potential reasons: You're in the wrong zone Nobody bothered to tell you that you were fired last week. The sysadmin for the global zone (probably your ex-girlfriend) enabled link protection mode on the zone with this sweet little command: root@global_zone:~# dladm set-linkprop -p \ protection=mac-nospoof,restricted,ip-nospoof vnic0 How'd your ex-girlfriend learn to do that?

  • TCO Comparison: Oracle Exadata vs IBM P-Series

    - by Javier Puerta
    Cost Comparison for Business Decision-makersOracle Exadata Database Machine vs. IBM Power SystemsHow to Weigh a Purchase DecisionOctober 2012 Download full report here In this research-based  white paper conducted at the request of Oracle, The FactPoint Group compares the cost of ownership of the Oracle Exadata engineered system to a traditional build-your-own (BYO) solution, in this case an IBM Power 770 (P770) with SAN storage.  The IBM P770 was chosen given it is IBM’s current most popular model, based on FactPoint primary and secondary research and IBM claims, and because at least one of the interviewed customers had specifically migrated from a P770 to Exadata, affording us a more specific data point for comparison. This research found that Oracle Exadata: Can be deployed more quickly and easily requiring 59% fewer man-hours than a traditional IBM Power Systems solution. Delivers dramatically higher performance typically up to 12X improvement, as described by customers, over their prior solution.  Requires 40% fewer systems administrator hours to maintain and operate annually, including quicker support calls because of less finger-pointing and faster service with a single vendor.  Will become even easier to operate over time as users become more proficient and organize around the benefits of integrated infrastructure. Supplies a highly available, highly scalable and robust solution that results in reserve capacity that make Exadata easier for IT to operate because IT administrators can manage proactively, not reactively.  Overall, Exadata operations and maintenance keep IT administrators from “living on the edge.”  And it’s pre-engineered for long-term growth. Finally, compared to IBM Power Systems hardware, Exadata is a bargain from a total cost of ownership perspective:  Over three years, the IBM hardware running Oracle Database cost 31% more in TCO than Exadata.

  • Questions about Code Reviews

    - by bamboocha
    My team plans to do Code Review and asked me to make a concept what and how we are going to make our Code Reviews. We are a little group of 6 team members. We use an SVN repository and write programs in different languages (mostly: VB.NET, Java, C#), but the reviews should be also possible for others, yet not defined. Basically I am asking you, how are you doing it, to be more precise I made a list of some questions I got: 1. Peer Meetings vs Ticket System? Would you tend to do meetings with all members, rather than something like a ticket system, where the developer can add a new code change and some or all need to check and approve it? 1. What tool? I made some researches on my own and it showed that Rietveld seems to be the program to use for non-git solutions. Do you agree/disagree and why? 2. A good workflow to follow? 3. Are there good ways to minimize the effort for those meetings even more? 4. What are good questions, every code reviewer should follow? I already made a list with some questions, what would you append/remove? are there any magic numbers in the code? do all variable and method names make sense and are easily understandable? are all querys using prepared statement? are all objects disposed/closed when they are not needed anymore? 5. What are your general experiences with it? What's important? Things to consider/prevent/watch out?

  • Suggested HTTP REST status code for 'request limit reached'

    - by Andras Zoltan
    I'm putting together a spec for a REST service, part of which will incorporate the ability to throttle users service-wide and on groups of, or on individual, resources. Equally, time-outs for these would be configurable per resource/group/service. I'm just looking through the HTTP 1.1 spec and trying to decide how I will communicate to a client that a request will not be fulfilled because they've reached their limit. Initially I figured that client code 403 - Forbidden was the one, but this, from the spec: Authorization will not help and the request SHOULD NOT be repeated bothered me. It actually appears that 503 - Service Unavailable is a better one to use - since it allows for the communication of a retry time through the use of the Retry-After header. It's possible that in the future I might look to support 'purchasing' more requests via eCommerce (in which case it would be nice if client code 402 - Payment Required had been finalized!) - but I figure that this could equally be squeezed into a 503 response too. Which do you think I should use? Or is there another I've not considered?

    Great Article, although it is a little dated at this point. Information Week Article Standards Matter: The Battle for Interoperability goes on Summary If you're guilty of relegating standards support to a "nice to have" feature rather than a requirement, you're part of the problem. If you want products to interoperate, be prepared to walk away if a vendor can't prove compliance. Don't be brushed off with promises of standards support "on the road map." The alternative is vendor lock-in and higher costs, including the cost of maintaining systems that don't work together. Standards bodies are imperfect and must do better. The alternative: splintered networks and broken promises. The point: "The secret sauce to a successful 'working standard' isn't necessarily IETF or another longstanding body," says Jonathan Feldman, director of IT services for the city of Asheville, N.C., and an InformationWeek Analytics contributor. "Rather, an earnest and honest effort by a group that has governance outside of a single corporation's control is what's important." In order to have true interoperability vendors as well as customers must be actively engaged in the standards process. Vendors must be willing to truly work together and not be protecting an existing product. Customers must also be willing to truly to work together and not be demanding a solution that only meets their needs but instead meets the needs of all participants. Ultimately, customers must be willing to reward vendor compliance by requiring compliance in products and services that they purchase and deploy. Managers that deploy systems without compliance to standards are only hurting themselves. Standards do matter. When developed openly and deployed compliantly standards deliver interoperability which provides solid business value.

  • Update Since Microsoft/PSC Office Open XML Case Study

    - by Tim Murphy
    In 2009 Microsoft released a case study about a project that we had done using the OOXML SDK 1.0 for Research Directors Inc.  Since that time Microsoft has released version 2.0 of the SDK and PSC has done significant development with it.  Below are some of the mile stones we have reached since the original case study. At the time of the original case study two report types had been automated to output as PowerPoint presentations.  Now that the all the main products have been delivered we have added three reports with Word document outputs and five more reports with PowerPoint outputs. One improvement we made over the original application was to create a PowerPoint Add-In which allows the users to tag a slide.  These tags along with the strongly typed SDK 2.0 allows for the code to use LINQ to easily search for slides in the template files.  This allows for a more flexible architecture base on assembling a presentation from copied slide extracted from the template. The new library we created also enabled us to create two new Word based reports in two weeks.  The library we created abstracts the generation of the documents from the business logic and the data retrieval.  The key to this is the mark up.  Content Controls are a good method for identifying sections of a template to be modified or replaced.  Join this with the concept of all data being generically either scalar or two dimensional and the code becomes more generic. In the end we found the OOXML SDK 2.0 to be a great tool for accelerating document generation development and creating happy clients.  del.icio.us Tags: PSC Group,OOXML,Case Study,Office Open XML,Word,PowerPoint

  • How to update entity states and animations in a component-based game

    - by mivic
    I'm trying to design a component-based entity system for learning purposes (and later use on some games) and I'm having some troubles when it comes to updating entity states. I don't want to have an update() method inside the Component to prevent dependencies between Components. What I currently have in mind is that components hold data and systems update components. So, if I have a simple 2D game with some entities (e.g. player, enemy1, enemy 2) that have Transform, Movement, State, Animation and Rendering components I think I should have: A MovementSystem that moves all the Movement components and updates the State components And a RenderSystem that updates the Animation components (the animation component should have one animation (i.e. a set of frames/textures) for each state and updating it means selecting the animation corresponding to the current state (e.g. jumping, moving_left, etc), and updating the frame index). Then, the RenderSystem updates the Render components with the texture corresponding to the current frame of each entity's Animation and renders everything on screen. I've seen some implementations like Artemis framework, but I don't know how to solve this situation: Let's say that my game has the following entities. Each entity have a set of states and one animation for each state: player: "idle", "moving_right", "jumping" enemy1: "moving_up", "moving_down" enemy2: "moving_left", "moving_right" What are the most accepted approaches in order to update the current state of each entity? The only thing that I can think of is having separate systems for each group of entities and separate State and Animation components so I would have PlayerState, PlayerAnimation, Enemy1State, Enemy1Animation... PlayerMovementSystem, PlayerRenderingSystem... but I think this is a bad solution and breaks the purpose of having a component-based system. As you can see, I'm quite lost here, so I'd very much appreciate any help.
