It is meant to become +a small set of generic interfaces for various game middleware +libraries, such as sound, input, graphics, and so on. It consists of +several independent modules, one for each of these areas. These may be +used together to build an entire game engine, or they can be used +individually as separate libraries. + +However, GOOI does NOT actually implement a game engine, or any new +fundamental functionality. More on that below. + +Currently there is only the Sound module, but more will come in the +future (including input, 2D/3D graphics, GUI, physics, file +system/archive access, and more.) + + +Main idea +--------- + +The idea behind to provide a uniform, consistent interface to other +game libraries. The library does not provide ANY functionality on its +own. Instead it connects to a backend implementation of your choice. + +The Sound module, for example, currently has backends for OpenAL +(output only), FFmpeg (input only) and for Audiere. Hopefully we'll +soon add IrrKlang, FMod, DirectSound and Miles to that. It can combine +libraries to get more complete functionality (like using OpenAL for +output and FFmpeg to decode sound files), and it's also easy to write +your own backend if you're using a different (or home-brewed) sound +system. + +Regardless of what backend you use, the front-end interface (found in +sound/sound.h) is identical, and as a library user you shouldn't +notice much difference at all if you swap one backend for another at a +later point. + +The goal in the long run is to support a wide variety of game-related +libraries, and as many backend libraries (free and commercial) as +possible, so that you the user will have to write as little code as +possible. + + + +What is it good for +------------------- + +The main point of GOOI, as we said above, is that it connects to any +library of your choice "behind the scenes" but provides the same, +super-simple interface front-end for all of them. There can benefit +you in many ways: + +- If you want to use a new library that GOOI support. You don't + have to scour the net for tutorials and usage examples, since much + of the common usage code is already included in the implementation + classes. + +- If you don't want to pollute your code with library-specific code. + The GOOI interfaces can help you keep your code clean, and its user + interface is often simpler than the exteral library one. + +- If you are creating a library that depends on a specific feature + (such as sound), but you don't want to lock your users into any + specific sound library. GOOI works as an abstraction that lets your + users select their own implementation. My own Monster scripting + language ( http://monsterscript.net ) will use this tactic, to + provide native-but-generic sound, input and GUI support, among other + features. + +- If you want to support multiple backends, or make it possible to + easily switch backends later. You can select backends at compile + time or even at runtime. Maybe you decide to switch to to a + commercial library at a late stage in development, or you discover + that your favorite backend doesn't work on all the platforms you + want to reach. + +The GOOI implementations are extremely light-weight - often just one +or two cpp/h pairs. You plug them directly into your program, there's +no separate build step required. + +Since the library aims to be very modularly put together, you can +also, in many cases, just copy-and-paste the parts you need and ignore +the rest. Or modify stuff without fearing that the whole 'system' will +come crashing down, because there is no big 'system' to speak of. + + +Past and future +--------------- + +GOOI started out as a spin-off from OpenMW, another project of mine +( http://openmw.sourceforge.net ). OpenMW is an attempt to recreate +the engine behind the commercial game Morrowind, using only open +source software. + +The projects are still tightly interlinked, and the will continue to +be until OpenMW is finished. That means that all near-future work on +GOOI for my part will be more or less guided by what OpenMW needs. But +I'll gladly accept external contributions that are not OpenMW-related. + + +Conclusion +---------- + +As you might have guessed, GOOI is more a concept in development than +a finished library right now. + +All feedback, ideas, concepts, questions and code are very +welcome. Send them to: korslund@gmail.com + +I will put up a forum later as well if there's enough interest. diff --git a/sound/.gitignore b/sound/.gitignore new file mode 100644 index 000000000..8b1378917 --- /dev/null +++ b/sound/.gitignore @@ -0,0 +1 @@ + diff --git a/sound/imp/.gitignore b/sound/imp/.gitignore new file mode 100644 index 000000000..8b1378917 --- /dev/null +++ b/sound/imp/.gitignore @@ -0,0 +1 @@ + diff --git a/sound/imp/audiere_imp.cpp b/sound/imp/audiere_imp.cpp new file mode 100644 index 000000000..ea094409f --- /dev/null +++ b/sound/imp/audiere_imp.cpp @@ -0,0 +1,94 @@ +#include "audiere_imp.h" + +// Exception handling +class Audiere_Exception : public std::exception +{ + std::string msg; + + public: + + Audiere_Exception(const std::string &m) : msg(m) {} + ~Audiere_Exception() throw() {} + virtual const char* what() const throw() { return msg.c_str(); } +}; + +static void fail(const std::string &msg) +{ + throw Audiere_Exception("Audiere exception: " + msg); +} + +using namespace audiere; +using namespace GOOI::Sound; + +AudiereManager::AudiereManager() +{ + needsUpdate = false; + has3D = false; + canRepeatStream = true; + canLoadFile = true; + canLoadSource = false; + + device = OpenDevice(""); + + if(device == NULL) + fail("Failed to open device"); +} + +// --- Manager --- + +Sound *AudiereManager::load(const std::string &file, bool stream) +{ return new AudiereSound(file, device, stream); } + + +// --- Sound --- + +AudiereSound::AudiereSound(const std::string &file, + AudioDevicePtr _device, + bool _stream) + : device(_device), stream(_stream) +{ + sample = OpenSampleSource(file.c_str()); + if(!sample) + fail("Couldn't load file " + file); + + buf = CreateSampleBuffer(sample); +} + +Instance *AudiereSound::getInstance(bool is3d, bool repeat) +{ + // Ignore is3d.
