  • How to avoid being forked into oblivion by a more powerful contributor?

    - by Den
    As recently reported here: Xamarin has forked Cocos2D-XNA, a 2D/3D game development framework, creating a cross-platform library that can be included in PCL projects. However the founder of the project that was forked says: The purpose of the MIT license is to unencumber your fair use. Not to encourage you to take software, rebrand it as your own, and then "take it in a new direction" as you say. While not illegal, it is unethical. It seems that the GitHub page of the new project doesn't even indicate that it's a fork in a typical GitHub manner, opting for an easily-removable History section instead (see bottom). So my questions are: Was Xamarin's action and the way the action was done ethical or not? Is it possible to avoid such a situation if you are a single developer or a small unfunded group of developers? I am hoping this could be either a wiki question or there will be some objective answers grounded on modern OSS ethics/philosophy.

  • How do games make money? What models do they use?

    - by cable729
    I'm trying to research the ways in which games make money. I want to know more about the models they use (free/premium, trial/subscription, free-to-play with micro-transactions, etc.). In addition, I want information on which models work for which games, what models are best for which age groups, etc. I've tried my best to find information, and Google hasn't turned anything up at all. I think I'll stop by my University's library and see if there's anything there. This may seem like a broad question, but I'm looking for links and titles of books, not typed-out answers.

  • Oculus Rift with Antichamber

    - by Scott Hainline
    Antichamber runs great on linux (steam version). But it is not playable with the Oculus Rift at this point. The issues are: 1) no headtracking 2) graphics are not being split and distorted by Oculus SDK My current plan is to use LD_PRELOAD to add the functionality, this seems to be the linux equivalent of DLL injection. Antichamber appears to be using SDL, I'm hoping this can be configured to use the headtracking data as a joystick and apply the graphics distortion, but I am not sure which functions I should be looking for. Is there a simpler way of getting these issues resolved? Is SDL the right choice here? Would appreciate any information on how the Unreal Engine 3 works under linux; and library injection too.

  • Using IE 9 as my primary browser

    - by Robert May
    With the release of Internet Explorer 9 RC the browser looks to be in a usable state.  So far, my experience has been positive. However, one area where I am having problems is when people are using the jQueryUI library.  Versions older than 1.8 cause IE 9.0 to be unable to drag and drop.  This is a real pain, especially at sites like Agile Zen, where dragging and dropping is a primary bit of functionality. Now that IE 9 is a release candidate, we’ll see how quickly these things improve.  I expect things to be rough, but so far, I’m really liking IE 9.  There’s more real estate than Chrome (it’s the tabs inline with the address bar) and its faster than Chrome 9.0 and FF 3.6.8 (as tested on my own machine). The biggest drawback so far is that because IE has been so badly behaved in the past, sites expect it to be badly behaved now, which is breaking things now. Technorati Tags: Internet Explorer

  • Getting front audio jacks to work

    - by Ashfame
    I run Ubuntu 10.10 on my Intel D945. My front audio ports don't work in Ubuntu, the rear one does. I never got it working earlier when I had Ubuntu 10.04 but this time I am going to try it again. My codec is SigmaTel STAC9227 My ALSA information is here. Handy details: !!ALSA Version !!------------ Driver version: 1.0.23 Library version: 1.0.23 Utilities version: 1.0.23 !!Loaded ALSA modules !!------------------- snd_hda_intel snd_hda_intel I know something that I will have to change the model of my module to make the front audio jack works but I couldn't find a model related line in my ALSA configuration file - /etc/modprobe.d/alsa-base.conf (I was able to get to that point in Ubuntu 10.04, may be something has changed). How can I proceed from here?

  • Understanding Unity3d physics: where is the force applied?

    - by Heisenbug
    I'm trying to understand which is the right way to apply forces to a RigidBody. I noticed that there are AddForce and AddRelativeForce methods, one applied in world space coordinate system meanwhile the other in the local space. The thing that I do not understand is the following: usually in physics library (es. Bullet) we can specify the force vector and also the force application point. How can I do this in Unity? Is it possible to apply a force vector in a specific point relative to the given RigidBody coordinate system? Where does AddForce apply the force?

  • How to get scripted programs governing game entities run in parallel with a game loop?

    - by Jim
    I recently discovered Crobot which is (briefly) a game where each player codes a virtual robot in a pseudo-C language. Each robot is then put in an arena where it fights against other robots. A robots' source code has this shape : /* Beginning file robot.r */ main() { while (1) { /* Do whatever you want */ ... move(); ... fire(); } } /* End file robot.r */ You can see that : The code is totally independent from any library/include Some predefined functions are available (move, fire, etc…) The program has its own game loop, and consequently is not called every frame My question is: How to achieve a similar result using scripted languages in collaboration with a C/C++ main program ? I found a possible approach using Python, multi-threading and shared memory, although I am not sure yet that it is possible this way. TCP/IP seems a bit too complicated for this kind of application.

  • Are the technologies used in an application part of the architecture, or do they represent implementation/detailed design details?

    - by m3th0dman
    When designing and writing documentation for a project an architecture needs to be clearly defined: what are the high-level modules of the system, what are their responsibilities, how do they communicate with each other, what protocols are used etc. But in this list, should the concrete technologies be specified or this is actually an implementation detail and need to be specified at a lower level? For example, consider a distributed application that has two modules which communicate asynchronously via AMQP protocol, mediated by a message broker. The fact that these modules use the Spring AMQP library for sending and receiving messages is a fact that needs to be specified in the architecture or is a lower-level detailed design/implementation detail?

  • Javascript A* path finding

    - by Veyha
    I am trying to learn A* path finding. I am using this library - https://github.com/qiao/PathFinding.js But there is one thing I don't understand how to do. To find a path from player.x/player.y (player.x and player.y are both 0) to 10/10 I use this code var path = finder.findPath(player.x, player.y, 10, 10, grid); This gives an array of where I need to move, but how do I apply this array to my player.x and player.y? The path structure looks like this path = [[0, 0], [1, 0], [1, 1], ..., [10, 10]]

  • How do I get my polygons to be lighted by either side?

    - by Molmasepic
    Okay, I am using Ogre3D and Gorilla(2D library for ogre3D) and I am making Gorilla::Screenrenderables in the open scene. The problem that I am having is that when I make a light and have my SR(screenrenderable) near it, it does not light up unless the face of the SR is facing the light... I am wondering if there is a way to maybe set the material or code(which would be harder) so the SR is lit up whether the vertices of the polygon are facing the light or not. I feel it is possible but the main obstacle is how I would go about doing this.

  • Best way to load rigid bodies from file

    - by Mel
    I'm trying to switch to bullet for physics simulation. Lemme just say first that I am so pleased with bullet's accuracy and performance. After messing around it for a bit, I'm now trying to load rigid bodies from files. Most of my models are in blender and with some searching, I was able to export them in .bullet format. However, loading the files into bullet doesn't look like an easy task. I've come across this page that points me to a sample application that loads bullet files. But then it goes and says that this loader is just a starting point. Is there any open source library out there that will allow me to load rigid bodies from a file? I don't really wanna spend that much time trying to create my own loader.

  • Banshee won't sync OGG format to my iphone

    - by Daze
    I have a jailbroken iphone 3g with 16 gigs of memory and I've been putting my music on it from banshee lately and have been having almost no issue. Unfortunately, I just added a few albums to my Banshee library and tried to sync them to my iphone, but every time I try, i see a hundred or so errors saying that the device doesn't support the ogg format and there was no converter found. I'm still pretty much a newb at this stuff, so please help me and dumb down your answer. I'm running 12.04 and again, using an iphone 3g with no sim card, but it's been jailbroken and is used primarily for it's music function.

  • What 2D game engines are there available for C++?

    - by dysoco
    I just realized there are not C++ 2D Game Engines that I know of. For example, something like Pygame in Python, or Slick2D in Java. We have the following: SDL - Too low level, not a Game Engine SFML - Handles more things than SDL and it's more modern, but still not a Game Engine. I like it, but I have found it a little bit buggy with the 2.0 version. Irrlitch - It's a Game Engine, but 3D focused. Ogre3D - Same as Irrlitch Allegro - This is a Game Engine, but it's C based, I'd like a modern C++ library. Monocle Engine - This looks like what I need... but sadly there is no Documentation, no community... nothing, all I have is the Github repo. So, do you know any ? I'd like to use C++, not C#, not Java: I'm just more comfortable with C++.

  • Automatically adding CD box art so that I can put it on my iPod.

    - by Seamus
    I know it's possible to automatically find CD covers for albums, because rhythmbox is doing it on the fly. (When I listen to stuff, it finds the CD cover online...) What I want is to get this information onto my ipod. As it stands pretty much all my songs have the default blank CD cover... I use gtkpod to transfer music to it. This needs to be an automatic process, because I have a large music library and I'm lazy and it's not exactly an important thing... I rip CDs I buy with the basic CD extractor, so all the files are in a Artist/Album/song.mp3 structure. (Yes I know, mp3 is evil, but iPod doesn't like .ogg so whatever)

  • Pronunciation in programming?

    - by Xepoch
    How do you correctly or erroneously pronounce programming terms? Any that you find need strict correction or history into the early CS culture? Programming char = "tchar" not care? ! = bang not exclamation? # = pound not hash? Exception #! = shebang * = splat not star? regex = "rej ex" not "regg ex"? sql = "s q l" not "sequel" (already answered, just i.e.) Unixen | = pipe not vertical bar? bin = bin as in pin , not as in binary? lib = lib as in library , not as in liberate? etc = "ett see" , not "e t c" (as in /etc and not "&c") Annoyance / = slash not backslash LaTeX = "laytek" not "lay teks"

  • Pros and cons of creating a print friendly page to remove the use of pdfs?

    - by Phil
    the company I work for has a one page invoice that uses the library tcpdf. they wanted to do some design changes that I found are just incredibly difficult for setting up in .pdf format. Using html/css I could easily create the page and have it print very nicely, but I have a feeling that I am over looking something. What are the pros and cons of setting up a page just for printing? What are the pros and cons of putting out a .pdf? I could also use the CSS inline so that if they wanted to download it and open it they could.

  • Tic-Tac-Toe game AI

    - by David Jones
    I'm looking into creating a simple tic tac toe/noughts and crosses game in Actionscript3 and am trying to understand the ideas behind the AI used in a game like this. I've seen some simplistic examples online but from what I've read a game tree or something like minimax is the best way to go about this. Can anyone help explain or reference any good examples of this? I've seen that there is a library called as3ds - data structures for game developers which has a number of classes that might help tie this together? Any info/examples or help is much appreciated.

  • Online architecture guide

    - by hunterman
    I am a newbie in gamedev, and I don't know about programmer's problems that can appear during development. So can you advice me some best practice for starting build new online multi-player game backend? I just saw reddraft server, and I think Spring library can also do some of its features. What is big difference? Do I need learn more spring or I have to use servers like reddraft or write these tools myself? I know that I need to learn hard and many - and the question is - what I should to learn now at the beginning? Thanks.

  • Can I use GPL software in a commercial application

    - by Petah
    I have 3 questions about the GPL here: If I use GPL software in my application, but don't modify or distribute it, do I have to release my application under the GPL? What if I modify some software that my application uses. Then do I have to release my application under the GPL, or can I just supply the modified software under the GPLs terms. And what if I use GPL software, but don't modify it, can I distribute it with my application? My case in point is, I have a PHP framework which I use the GeSHi library to highlight some output. Because GeSHi is GPL, does my framework have to be GPL? Can I modify GeSHi for particular use cases of my application if I supply the modifications back to the GeSHi maintainers? Can I redistribute my framework with GeSHi?

  • Allow any arguments for a given command with sudo

    I have the following sudo config entry which I added via sudo visudo: mark ALL = NOPASSWD: /usr/bin/lxc-ls* I can run lxc-ls with my user fine but I can't append any parameters without it demanding I prefix the command with sudo. $ whoami mark $ lxc-ls test-container $ lxc-ls --fancy lxc-ls: error: You must be root to access advanced container properties. Try running: sudo /usr/bin/lxc-ls Any idea how I can edit via sudo visudo to allow for any argument after the command? I don't want to prefix the command with sudo as I'm using a python library to execute the command and it's being funny about sudo prefixes.

  • How can I get my meshes to work with Bullet Physics?

    - by Molmasepic
    The problem is that I'm trying to use my meshes with Bullet Physics for the collision part of my game. When I attempted doing this method with my GLM(model loading library by nate robins) model, I get a segmentation fault in the debug, so I figured that it doesnt like the coordinate variables of the model. If i use blender to export my model as a collision file, what type of file should I use? I have heard of a .bullet exporter, but i dont know hot to integrate this python script into my Blender 2.5 program.
