OpenMW - the completely unofficial reimplementation of Morrowind
================================================================
OpenMW is an open source reimplementation of the Morrowind game
engine. For more information, see README.txt or
http://openmw.snaptoad.com/
Installation from source
========================
Supported Unix platforms:
-------------------------
OpenMW has been tested for the most part on 32bit Ubuntu Linux
8.04. It should, however, also work on most other 32bit
distributions.
FreeBSD is also known to work with recent versions of GDC (the D
compiler), but you might need to rebuild some of the dependencies from
source yourself. (If you have done this and can give more specific
instructions, please let me know!)
64bit systems are NOT supported.
If you manage to build OpenMW on a platform not listed here, or want
to try, please let me know!
Dependencies:
-------------
Dependencies needed to build OpenMW:
OGRE 1.6.2 (3d engine)
OIS-1.0.0 (input system)
MyGUI 2.2.2 (GUI system for OGRE)
Bullet 2.74 (collision and physics library)
Monster 0.12 (scripting engine, included)
OpenAL (3d sound system)
libavcodec,
libavformat (For MP3 playback)
gcc and g++ (C++ compiler)
GNU make (build tool for C++ files)
DMD 1.036 (D compiler)
or GDC 4.1.3 (alternative D compiler)
The above versions are the ones I have tested recently, but other
versions might work. OGRE, OpenAL and the other libraries have
dependencies of their own, so I recommend using an automated package
tool to install as many of these as possible. On Ubuntu, for example,
try typing:
sudo apt-get install libogre-dev libavcodec-dev libavformat-dev libois-dev build-essential g++ gdc
On Arch Linux, get the following packages from AUR:
ogre
mygui-svn
bullet-2.75
openal
ffmpeg
ois
dmd
libphobos
dsss
(On Arch you also need to change the Bullet libraries to
-llBulletDynamics -llBulletCollision -llLinearMath in dsss.conf, or
similarily in the Makefile if you prefer building with make.)
A note about OpenAL: The library found in most Linux distributions
(0.0.8 SI) is outdated. Some distributions are now changing to OpenAL
Soft, which has a less hardware-dependent implementation. If you
experience sound problems (like stuttering music), try switching to
OpenAL Soft.
Note to UBUNTU 8.10 users: There's a problem with Pulseaudio in this
Ubuntu version. If you find that sound doesn't work or you get error
messages related to sound, try this page:
http://idyllictux.wordpress.com/2008/10/29/alsa-instead-of-pulseaudio-for-ubuntu-810-intrepid-a-non-destructive-way/
libavcodec and libavformat are part of the FFmpeg package, which is
part of the 'mplayer' project. Note that some of the codecs might be
patent protected in your country or area.
If you want to install Ogre, Bullet, OpenAL, OIS or FFmpeg manually,
try:
OGRE: http://ogre3d.org/
MyGUI: http://www.ogre3d.org/wiki/index.php/MyGUI
OpenAL: http://openal.org/
Linux source: http://kcat.strangesoft.net/openal.html
OIS: http://sourceforge.net/projects/wgois/
FFmpeg: http://ffmpeg.mplayerhq.hu/download.html
Bullet: http://bulletphysics.com/
Monster: Included with OpenMW.
Setting up Bullet
-----------------
Bullet is not yet included in most Linux distributions, and must
usually be compiled manually. Consult the documentation included with
Bullet for instructions on compiling.
After compiling, you should have the files libbulletdynamics.a,
libbulletcollision.a and libbulletmath.a. (Depending on build method,
you may end up with names like libLibBulletDynamics.a instead.) Copy
or link these to bullet/ in the openmw directory (and rename them to
the libbulletdynamics.a etc if necessary.)
Example:
cd openmw/bullet
ln -s ~/software/bullet-2.74/src/BulletCollision/libbulletcollision.a .
Next, create a link to the "src" directory in openmw/include/bullet/ .
Example:
cd openmw
mkdir -p include
cd include
ln -s ~/software/bullet-2.74/src bullet
Setting up MyGUI
----------------
Like Bullet, MyGUI is still too fresh to be prepackaged with the major
Linux distros. To make matters worse, there's not even a recent source
package. You'll need to get the source from svn (at
https://my-gui.svn.sourceforge.net/svnroot/my-gui/trunk ). Revisions
at around 1738 should work, but newer revisions are probably better.
Once you've compiled the sources, install normally using 'make
install' (check the MyGUI docs for any instructions), and the OpenMW
makefile should pick up its location automatically.
Choosing a D compiler
---------------------
The above apt-get command installs the GDC compiler. There are
currently two choices for the D compiler, DMD and GDC. DMD is the
"official" compiler and is updated more often, while GDC is a
completely open source front-end for GCC (the GNU compiler.) Both
should work equally well with OpenMW.
If you want to install GDC manually, go to
http://sourceforge.net/projects/dgcc
If you want to use DMD instead, it can be found at:
http://digitalmars.com/d/1.0/dmd-linux.html
Note that the DMD unstable branch (2.000 and up) will NOT currently
work with OpenMW. Use the stable branch (1.x) instead.
Also note that DMD is only available on 32 bit x86 Linux - other
operating systems or architectures will have to use GDC. Note however
that GDC might be unstable on these platforms as well, especially on
64 bit platforms.
Building:
---------
After installing all the dependencies, you can try running "make cpp"
first to see if the C++ parts compile. You may need to alter the
Makefile if you are using non-standard include paths, etc. If you have
DSSS installed (a D build tool), type:
dsss build
If you do NOT have DSSS, try using make
make all
You might need to edit the Makefile to match your setup. If you are
using DMD instead of GDC, try changing the compiler from "gdmd" to
"dmd" in the Makefile.
If all else fails, you can try the build script:
./build_openmw.sh
This build method is deprecated and only works with gdc.
Configuration
=============
Before you can run OpenMW, you have to help it find the Morrowind data
files. The 'openmw' program needs the files Morrowind.esm and
Morrowind.bsa, and the directories Sound/ and Music/ from your
"Morrowind\Data Files\" directory. By default it expects to find these
in the data/ directory. (This can be changed in openmw.ini)
I recommend creating a symbolic link to your original Morrowind
install. For example, if you have Morrowind installed in:
c:\Program Files\Bethesda Softworks\Morrowind\
and your windows c: drive is mounted on /media/hda1, then run the
following command:
ln -s "/media/hda1/Program Files/Bethesda Softworks/Morrowind/Data Files/" data
Also, if you have OGRE installed in a non-standard directory (ie. NOT
in /usr/lib/OGRE), you have to change the PluginFolder in the file
plugins.cfg.linux.
The first time you run openmw you will be asked to set screen
resolution and other graphics settings. You can bring this dialogue up
at any time with the -oc command line switch. I don't recommend using
fullscreen mode yet, since it might mess up your screen and input
settings if the program crashes.
Running OpenMW
==============
If Azura is with you and all the stars and planets are aligned in your
favor, you should now be able to run OpenMW using the program called
'openmw'.
Write openmw -h to see a list of options.
Running without parameters should bring you into the cave called Assu,
or the last cell loaded. Move around with WASD (or arrow keys), change
physics mode (walking, flying, ghost) with 't', exit with 'q' or
escape.
To load another cell, specify the cell name on the command line. Use
the 'esmtool' program to get a list of cells. Note that you must use
quotation marks "" if the cell name contains spaces or other weird
characters.
Enjoy! ;-)

OpenMW - the completely unofficial reimplementation of Morrowind
================================================================
OpenMW is an open source reimplementation of the Morrowind game
engine. For more information, see README.txt or
http://openmw.snaptoad.com/
Building from source
====================
Supported Windows platforms:
----------------------------
Mostly tested on Windows XP, but Vista is also rumored to work. If you
manage to compile or run OpenMW on another Windows platform
(9x/Me/NT/2000), please let me know.
At the moment, only command line building is supported.
Dependencies:
-------------
To compile OpenMW you need Mingw with g++ (a C++ compiler) and gdc
(the D compiler.) You can find them here:
Mingw: http://sourceforge.net/projects/mingw/
gdc: http://sourceforge.net/projects/gdcwin/
Note that the "official" D compiler, DMD, will not currently work on
Windows, because it is uses an object format incompatible with most
C++ compilers.
All library dependencies are included in the file
openmw-dll-pack.zip. Simply download this file and unpack it in the
same directory as the OpenMW source code. You should not need to
download any other dependencies.
Setting everything up
---------------------
First, install Mingw (get the automatic installer.) Make sure gcc and
g++ packages are selected.
Next install the gdcwin installer (the package named 'gdc') and
install it in the same directory as Mingw.
Open a command line. Set up your PATH to include Mingw and gdc
(eg. "set PATH=%PATH%;c:\mingw\bin").
Next you must make sure the D include files are found by the
compiler. Run the following command:
set DFLAGS=-Ic:\mingw\include\d\3.4.5\
where the path following -I is the path of your Mingw GDC include
directory.
Make sure the commands g++ and gdc work (should output "no input
files".)
Building
--------
To build, simply run build_openmw.bat
Running
-------
For instructions on how to set everything up after compilation, see
README-win32.txt.
Good luck!

OpenMW - the completely unofficial reimplementation of Morrowind
================================================================
OpenMW is an open source reimplementation of the Morrowind game
engine. For more information, see README.txt or
http://openmw.snaptoad.com/
Running OpenMW
==============
OpenMW consists of three separate downloads:
openmw-0.X_win32.zip - binary package (with EXE file)
openmw-0.X.zip - source code
openmw-dll-pack.zip - library pack
You only need the binary or the source package, not both. The DLL pack
is needed in both cases.
NOTE: If downloaded the SOURCE release, please read COMPILE-win32.txt
before reading the rest of this file.
Configuration
-------------------
OpenMW assumes you have the Morrowind data files in c:\Program
Files\Bethesda Softworks\Morrowind\Data Files\ . If this is not where
you have installed Morrowind, you should edit the file openmw.ini.
Running
-------
Just run openmw.exe and enjoy! ;-)
The first time you run OpenMW, you will be asked to set screen
resolution and other graphics settings. To be safe, I don't recommend
setting fullscreen mode on the first run. You can bring up the
dialogue at any time by using the -oc switch.
Move around with WASD or arrow keys, change physics mode (walking,
flying, ghost) with 't', exit with 'q' or escape. You can change key
bindings in the openmw.ini file.
You start in a cell called "Assu". You can change this in openmw.ini or
by specifying a cell name on the command line.
Write openmw -h on the command line to see a complete list of options.

OpenMW - the completely unofficial reimplementation of Morrowind
================================================================
Written by Nicolay Korslund
Email: korslund@gmail.com
WWW: http://openmw.sourceforge.net
License: See GPL3.txt
Current version: 0.6
Date: 2009 mar. 2
QUICK NOTE: You must own and install Morrowind before you can use
OpenMW. Let me repeat that: OpenMW will NOT run if you do not have
Morrowind installed on your system!
Installation
============
Currently supported platforms are Windows, Linux and FreeBSD. Most
testing is done on Ubuntu 8.04 and Windows XP Professional.
For instructions, see one of the following:
README-win32.txt - instructions for binary Windows release
COMPILE-win32.txt - instructions for building from source on Windows
COMPILE-linux.tx - instructions for building from source on Linux / Unix
Linux 64 does NOT work, because of problems with the D compiler. We
hope to sort this out at some point, but right now it's simply not
supported.
Programs included in this package:
==================================
openmw - The main program. Run openmw -h for a list of options.
esmtool - Used to inspect ES files (ESM, ESP, ESS). Run without
arguments to get a list of options.
bsatool - Tool for viewing and extracting files from BSA archives.
(Can also be used to test the NIF parser on a BSA.)
niftool - Decodes one or more NIF files and prints the details.

// value. Sets all the elements in the array
// to the value. Takes an int specifying the
// element/value size.
CatArray, // Concatinate two arrays, on the stack.
CatLeft, // Concatinate an array with a left
// element. The element is pushed first, so
// the array index is first off the stack.
CatRight, // Concatinate with right element. Array
// pushed first, then element. Both these take
// an element size (int).
ReverseArray, // Reverses an array. The index is on the
// stack. The array is reversed in place, and
// the index is left untouched on the stack.
CreateArrayIter, // Create array iterator. Expects the stack to
// hold an index(int), a value(int) and an
// array index, pushed in that order. Replaces
// the array index with an iterator index,
// sets the rest to reflect the first element
// in iteration. Takes two byte parameters
// that are either 0 or 1. If the first is
// set, then the array is iterated in the
// reverse order. If the second is set, then
// the value is a reference, ie. changes to it
// will be transfered back to the orignal
// array. Pushes false if the array is empty,
// true otherwise.
CreateClassIter, // Create a class iterator. Expects the
// stack to hold a value (object index =
// int). Takes one int parameter, which is the
// class index. Pushes false if no objects
// exist, true otherwise.
IterNext, // Iterate to the next element. Leaves the
// iteration variables on the stack. Pushes
// false if this was the last element, true
// otherwise.
IterBreak, // Break off iteration. Does exactly the same
// thing as IterNext would done if it had just
// finished the last iteration step, except it
// does not push anything onto the stack.
IterUpdate, // Update the original array or data from
// reference variables in this
// iteration. Called whenever a 'ref' variable
// is changed, to make sure that the changes
// take effect. Takes an int parameter that
// gives the stack position (in the current
// frame) of the iterator index.
GetStack, // Internal debugging function. Pushes the
// current stack position on the stack. Might
// be removed later.
MultiByte, // This instruction consists of a second byte
// or an extra int. Reserved for future
// use. This is intended for when / if the
// number of instructions exceeds
// 256. Instructions in this list with numbers
// >= 256 will be coded in this way.
// Instructions appearing after the MultiByte mark might be coded
// as multi-byte. They are handled in a more time-consuming
// matter. You should only use this space for instructions that
