Welcome to Mangle v0.1

|
||||
Mangle is the project name for a small set of generic interfaces for
|
||||
various game middleware libraries, such as sound, input, graphics, and
|
||||
so on. You can imagine that it stands for "Minimal Abstraction Game
|
||||
Layer", if you like. It will consist of several more or less
|
||||
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, Mangle does NOT actually implement a game engine, or any new
|
||||
fundamental functionality. More on that below.
|
||||
|
||||
Currently there's modules for sound and streams / archives (virtual
|
||||
file systems.) More will come in the future (including input, 2D/3D
|
||||
graphics, GUI, physics, and more.)
|
||||
|
||||
|
||||
Main idea
|
||||
---------
|
||||
|
||||
The idea behind Mangle is 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 (or of your making.)
|
||||
|
||||
The Sound module, for example, currently has backends for OpenAL
|
||||
(output only), FFmpeg (input only) and for Audiere. Hopefully we'll
|
||||
add IrrKlang, FMod, DirectSound, Miles and more in the future. 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 interfaces (found
|
||||
eg. in sound/output.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. It should Just Work.
|
||||
|
||||
The interfaces themselves are also quite simple. Setting up a sound
|
||||
stream from FFmpeg or other decoder into OpenAL can be quite hairy -
|
||||
but with Mangle the hairy parts have already been written for you. You
|
||||
just plug the parts together.
|
||||
|
||||
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 Mangle, 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 Mangle 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 Mangle interfaces can help you keep your code clean, and its
|
||||
user interface is often simpler than the exteral library one.
|
||||
|
||||
- If you want to quickly connect different libraries together, it
|
||||
really helps if they speak a common language. The Mangle interfaces
|
||||
are exactly that - a common language between libraries. Do you need
|
||||
Audiere to load sounds from a weird archive format only implemented
|
||||
for PhysFS, all channeled through the OGRE resource system? No
|
||||
problem!
|
||||
|
||||
- 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. Mangle works as an abstraction that lets
|
||||
your users select their own implementation.
|
||||
|
||||
- If you want to support multiple backends for your game/app, or want
|
||||
to make it possible to easily switch backends later. You can select
|
||||
backends at compile time or even at runtime. For example you might
|
||||
want to switch to to a commercial sound library at a later stage in
|
||||
development, or you may want to use a different input library on
|
||||
console platforms than on PC.
|
||||
|
||||
The Mangle implementations are extremely light-weight - often just one
|
||||
or two cpp/h pairs per module. You can plug them directly into your
|
||||
program, there's no separate library building 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
|
||||
---------------
|
||||
|
||||
Mangle started out as (and still is) a spin-off from OpenMW, another
|
||||
project I am personally working on ( http://openmw.com/ ). 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 they will continue to
|
||||
be until OpenMW is finished. Most near-future work on Mangle will be
|
||||
focused chiefly on OpenMW at the moment. However I will gladly include
|
||||
external contributions and suggestions that are not OpenMW-related if
|
||||
someone sends them to me.
|
||||
|
||||
|
||||
Conclusion
|
||||
----------
|
||||
|
||||
As you might have guessed, Mangle 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.

TODOs:

- mpg123 impressively enough supports custom stream reading. Which

means we could (and SHOULD!) support reading from Mangle::Streams
|

as well. But I'll save it til I need it.
|
||||
|
||||
An alternative way to do this is through feeding (which they also
|
||||
support), but that's more messy.
|
||||
|
||||
- the library also supports output, via various other sources,
|
||||
including ALSA, OSS, PortAudio, PulseAudio and SDL. Using this
|
||||
library as a pure output library (if that is possible) would be a
|
||||
nice shortcut over using those libraries - OTOH it's another
|
||||
dependency.
|
||||
|
||||
- we could implement seek(), tell() and size(), but they aren't
|
||||
really necessary. Furthermore, since the returned size is only a
|
||||
guess, it is not safe to rely on it.
