  • Optional structural typing possibilty in C++ or anyother language?

    - by ambhai
    In C++ how to tell compiler that Ogre::Vector3 IS_SAME_AS SomeOtherLIB::Vector3 ? I feel that.. in languages like c++ which are not structural typed but there are cases when it makes sense. Normally as game developer when working with 4+ libraries that provide sort or their own Vector3 implementation. The code is littered with ToOgre, ToThis, ToThat conversion function. Thats a lot of Float3 copying around which should not happen on first place. Is in C++ or any other languages where we dont have to convert (copying) from one type to another which is essentially the samething. But any solution in C++ as most of the good gamedevs libs are for c/c++.

  • sigsetjmp and siglongjmp inside signal handler

    - by EpsilonVector
    How do I: sigsetjmp inside the handler and then return from the handler such that the signal will be unmasked once I siglongjmp back to this point? In pseudo code this is sort of the function that I have: signal_handler(){ if(sigsetjmp(env[i++])) return; else siglongjmp(env[i]); } It's supposed to be the context switch code for user threads in Linux.

  • How to get a physics engine like Nape working?

    - by Glacius
    Introduction: I think Nape is a relatively new engine so some of you may not know it. It's supposedly faster than box2d and I like that there is decent documentation. Here's the site: http://code.google.com/p/nape/ I'm relatively new to programming. I am decent at AS3's basic functionality, but every time I try to implement some kind of engine or framework I can't even seem to get it to work. With Nape I feel I got a little further than before but I still got stuck. My problem: I'm using Adobe CS5, I managed to import the SWC file like described here. Next I tried to copy the source of one of the demo's like this one and get it to work but I keep getting errors. I made a new class file, copied the demo source to it, and tried to add it to the stage. My stage code basically looks like this: import flash.Boot; // these 2 lines are as described in the tutorial new Boot(); var demo = new Main(); // these 2 are me guessing what I'm supposed to do addChild(demo); Well, it seems the source code is not even being recognized by flash as a valid class file. I tried editing it, but even if I get it recognized (give a package name and add curly brackets) but I still get a bunch of errors. Is it psuedo code or something? What is going on? My goal: I can imagine I'm going about this the wrong way. So let me explain what I'm trying to achieve. I basically want to learn how to use the engine by starting from a simple basic example that I can edit and mess around with. If I can't even get a working example then I'm unable to learn anything. Preferably I don't want to start using something like FlashDevelop (as I'd have to learn how to use the program) but if it can't be helped then I can give it a try. Thank you.

  • Escape doube and single backslashes in a string in Ruby

    - by Nick Gorbikoff
    Hello. I'm trying to access a network path in my ruby script on a windows platform in a format like this. \\servername\some windows share\folder 1\folder2\ Now If I try to use this as a path, it won't work. Single backslashes are not properly escaped for this script. path = "\\servername\some windows share\folder 1\folder2\" d = Dir.new(path) I tried everything I could think of to properly escape slashes in the path. However I can't escape that single backslash - because of it's special meaning. I tried single quotes, double quotes, escaping backslash itself, using alternate quotes such as %Q{} or %q{}, using ascii to char conversion. Nothing works in a sense that I'm not doing it right. :-) Right now the temp solution is to Map a network drive N:\ pointing to that path and access it that way, but that not a solution. Does anyone have any idea how to properly escape single backslashes? Thank you

  • Java apache commons library source license question

    - by llm
    I want to use functionality from a certain method in apache commons StringUtils. I currently do not have the option of just using the library as one would normally do. I found the source for the method I need and my question is: am I free (legally) to use this code (just a method out of the library) or do I have to use the entire library? If its ok, what kind of attribution would I need in my code, if any? Thanks.

  • Help to convert PostgreSQL dates into SQL Server dates

    - by Earlz
    Hello I'm doing some data conversion from PostgreSQL to Microsoft SQL Server. So far it has all went well and I almost have the entire database dump script running. There is only one thing that is now messed up: dates. The dates are dumped to a string format. These are two example formats I've seen so far: '2008-01-14 12:00:00' and the more precise '2010-04-09 12:23:45.26525' I would like a regex (or set of regexs) that I could run so that will replace these with SQL Server compatible dates. Anyone know how I can do that?

  • LINQ Join for Orderby only

    - by RandomBen
    I am trying to run this code: ItemTaxonomy iTaxonomy = from itemTaxonomy in connection.ItemTaxonomy where itemTaxonomy.Item.ID == itemView.ID orderby itemTaxonomy.Taxonomy.Name select itemTaxonomy; When I compiled it I get the error: Cannot implicitly convert type 'System.Linq.IOrderedQueryable<Website.Models.ItemTaxonomy>' to 'Website.Models.ItemTaxonomy'. An explicit conversion exists (are you missing a cast?) I believe the issue is with orderby itemTaxonomy.Taxonomy.Name but I am just trying to order by the name of Taxonomy items instead of their IDs. Is there a way to do that?

  • Possible to be adequate with respect to decision/condition coverage but not block coverage?

    - by bparker
    Following up on a debate that I was having with a colleague. What is the community's opinion on whether or not a section of code can be adequate with respect to decision coverage (all possible decisions have evaluated to true and false) but not block coverage, and if a section of code can be adequate with respect to condition coverage (each simple condition in a compound conditions has evaluated to true and false) but not block coverage. Thanks.

  • How do I output Unicode characters as a pair of ASCII characters?

    - by ChrisF
    How do I convert (as an example): Señor Coconut Y Su Conjunto - Introducciõn to: Señor Coconut Y Su Conjunto - Introducciõn I've got an app that creates m3u playlists, but when the track filename, artist or title contains non ASCII characters it doesn't get read properly by the music player so the track doesn't get played. I've discovered that if I write the track out as: #EXTINFUTF8:76,Señor Coconut Y Su Conjunto - Introducciõn #EXTINF:76,Señor Coconut Y Su Conjunto - Introducciõn #UTF8:01-Introducciõn.mp3 01-Introducciõn.mp3 Then the music player will read it correctly and play the track. My problem is that I can't find the information I need to be able to do the conversion properly.

    Possible Duplicate: What static analysis tools are available for C#? At work we tend to use two tools for analysing our projects, FxCop to analyse our managed code and StyleCop to have consistent code layout.

    I want to have a seperate project that runs my server communication code in a normal JVM for the purposes of integration testing.
