PrBoom 2.5.0
|
|
============
|
|
|
|
PrBoom is a version of the classic 3D shoot'em'up game Doom, originally
|
|
written by id Software.
|
|
|
|
See the file AUTHORS in this distribution for a list of authors and
|
|
other contributors, and a history of the projects PrBoom is derived
|
|
from.
|
|
|
|
PrBoom is made available under the GNU General Public License. See the
|
|
file COPYING included in this distribution for details.
|
|
|
|
Please see the NEWS file included for changes since the previous version.
|
|
|
|
Game data - WADs
|
|
----------------
|
|
|
|
(This section is aimed at people not familiar with Doom and the
|
|
data files it uses.)
|
|
|
|
PrBoom is a game engine - it provides a program to play Doom levels, but
|
|
it doesn't include any levels itself. More importantly, you need all the
|
|
sounds, sprites, and other graphics that make up the Doom environment.
|
|
So to play PrBoom, you need one of the main Doom date files from id
|
|
Software - either doom.wad, doom2.wad, tnt.wad or plutonia.wad from one
|
|
of the commercial Doom games, or the shareware doom1.wad. This file
|
|
is called the IWAD.
|
|
|
|
PrBoom also supports playing Doom add-on levels, called "PWADs", which
|
|
are small extra .wad files which just contain extra levels or other
|
|
resources. PWADs are ONLY ADD-ONS, you still need the original IWAD
|
|
that they are designed to work with. In practice, most PWADs on the
|
|
Internet require doom2.wad (although some work with doom.wad).
|
|
|
|
If you don't own any of the Doom games, get the shareware doom1.wad
|
|
from doom19s.zip on Doomworld's shareware download page. But note that you
|
|
will not be able to play most add-ons.
|
|
http://www.doomworld.com/files/shareware.shtml
|
|
|
|
Windows Installation
|
|
--------------------
|
|
|
|
Just extract the zip to a directory of your choice and copy your IWAD
|
|
files into it. Now you can make shortcuts and add "-iwad filename.wad"
|
|
to them.
|
|
|
|
The SDL_mixer library used by PrBoom supports software MIDI music
|
|
synthesis. If you want to hear the Doom music, you need a set of
|
|
Timidity instrument patches. Do a web search for timidity patch sets,
|
|
there are plenty around.
|
|
These patch sets are a large download (>5megs).
|
|
SDL_mixer does not currently support hardware MIDI synthesis. But we
|
|
have added a hacked version of SDL_mixer with native midi support. If
|
|
you like to try it out, rename SDL_mixer_beta.dll to SDL_mixer.dll.
|
|
You should rename the original SDL_mixer.dll before. Tell us if it
|
|
works or not. Please note, that there might be bugs in the native midi
|
|
implementation.
|
|
|
|
Linux Installation
|
|
------------------
|
|
|
|
For UNIX, Linux, and other POSIX systems, you need the SDL libraries in
|
|
order to use PrBoom. If you haven't already done so, visit
|
|
http://prboom.sourceforge.net/linux.html and follow the instructions there
|
|
for your system, downloading the necessary libraries, and either
|
|
installing the binary RPM package or compiling PrBoom from source.
|
|
|
|
Once you've done that, you'll need to copy your IWAD file (see the section
|
|
above if you don't know what this is) to a directory where PrBoom can find
|
|
it. Make /usr/local/share/games/doom/, and copy your IWAD (all of your
|
|
IWADs, if you own more than one) to that directory.
|
|
|
|
Mac OS Installation
|
|
-------------------
|
|
|
|
Copy your IWAD (see above) into your home folder under
|
|
Library:Application Support:PrBoom (this folder will be created for you the
|
|
first time you run PrBoom).
|
|
|
|
First Use
|
|
---------
|
|
|
|
If it's the first time you've run PrBoom, you'll need to do some configuring
|
|
to get the controls and display right for you.
|
|
|
|
On a new installation, PrBoom runs at 640x480 resolution. If you have used
|
|
PrBoom before, you may have an old config file in your home directory which
|
|
specifies a lower resolution, such as Doom's normal 320x200. You can use the
|
|
-width and -height parameters to select a higher resolution, e.g.:
|
|
|
|
prboom -width 640 -height 400
|
|
|
|
sets the resolution. This setting is remembered for future sessions. For
|
|
other parameters, see the included README.command-line.
|
|
|
|
You may also wish to customise the key bindings. PrBoom's default keybindings
|
|
are the same as the original Doom; unlike original Doom, you can change key
|
|
bindings in the game. In the in-game menus, go to Options, Settings, Key
|
|
Bindings.
|
|
|
|
On Mac OS X, you can't use the command line, but after running the program
|
|
once, you can edit YOURHOME:Library:Application Support:PrBoom:prboom.cfg to
|
|
change settings like your screen resolution.
|
|
|
|
Features
|
|
--------
|
|
|
|
This is all the features PrBoom has compared to the original Doom game
|
|
- it's intended to give you an idea of the enhancements, rather than
|
|
burying you in details.
|
|
|
|
See http://prboom.sourceforge.net/about.html for an HTML version of
|
|
this list.
|
|
|
|
This is shamelessly modelled on Boom's changes pages. By each
|
|
change, there's the name of the port the feature comes from (so it's
|
|
compatible with).

Other Tips
|
|
----------
|
|
|
|
On Linux, SDL tries to detect an appropriate video device automatically.
|
|
If you want to overrite the default, you can set the SDL_VIDEODRIVER
|
|
enviromental variable. At a bash prompt, this is as easy as running:
|
|
|
|
SDL_VIDEODRIVER=fbcon prboom
|
|
or
|
|
SDL_VIDEODRIVER=svga prboom
|
|
|
|
Details
|
|
-------
|
|
|
|
Details on these extra features are split into separate text files:
|
|
|
|
README.demos provides a guide to PrBoom's demo support
|
|
README.compatibility describes PrBoom's various compatibility
|
|
options and modes
|
|
README.command-line gives a command line reference for prboom,
|
|
prboom-game-server, and the format of boom.cfg.
|
|
On UNIX/Linux systems use the man pages instead.

Editing features are not covered in the docs with this package. We plan
|
|
to bundle the editing docs as a separate download. Watch our website
