1.0) About:
---- ------
OpenTTD is a clone of Transport Tycoon Deluxe, a popular game originally
written by Chris Sawyer. It attempts to mimic the original game as closely
as possible while extending it with new features.
OpenTTD is licensed under the GNU General Public License version 2.0. For
more information, see the file 'COPYING'.
2.0) Contacting:
---- ----------
The easiest way to contact the OpenTTD team is by submitting bug reports or
posting comments in our forums. You can also chat with us on IRC (#openttd
on irc.oftc.net).
The OpenTTD homepage is http://www.openttd.org/.
You can also find the OpenTTD forums at
http://forum.openttd.org/
2.1) Reporting Bugs:
---- ---------------
To report a bug, please create a Flyspray account and follow the bugs
link from our homepage. Please make sure the bug is reproducible and
still occurs in the latest daily build or the current SVN version. Also
please look through the existing bug reports briefly to see whether the bug
is not already known.
The Flyspray project page URL is: http://bugs.openttd.org/
Please include the following information in your bug report:
- OpenTTD version (PLEASE test the latest SVN/nightly build)
- Bug details, including instructions how to reproduce it
- Platform and compiler (Win32, Linux, FreeBSD, ...)
- Attach a saved game *and* a screenshot if possible
- If this bug only occurred recently please note the last
version without the bug and the first version including
the bug. That way we can fix it quicker by looking at the
changes made.
- Attach crash.dmp, crash.log and crash.sav from the data
directory if they exist.
2.2) Reporting Desyncs:
---- ------------------
As desyncs are hard to make reproducable OpenTTD has the ability to log all
actions done by clients so we can replay the whole game in an effort to make
desyncs better reproducable. You need to turn this ability on. When turned
on an automatic savegame will be made once the map has been constructed in
the 'save/autosave' directory, see OpenTTD directories to know where to find
this directory. Furthermore the log file 'commands-out.log' will be created
and all actions will be written to there.
To enable the desync debugging you need to set the debug level for 'desync'
to at least 1. You do this by starting OpenTTD with '-d desync=<level>' as
parameter or by typing 'debug_level desync=<level>' in OpenTTD's internal
console.
The desync debug levels are:
0: nothing.
1: dumping of commands to 'commands-out.log'.
2: same as 1 plus checking vehicle caches and dumping that too.
3: same as 2 plus monthly saves in autosave.
4 and higher: same as 3
Restarting OpenTTD will overwrite 'commands-out.log'. OpenTTD will not remove
the savegames (dmp_cmds_*.sav) made by the desync debugging system, so you
have to occasionally remove them yourself!
The naming format of the desync savegames is as follows:
dmp_cmds_XXXXXXXX_YYYYYYYY.sav. The XXXXXXXX is the hexadecimal representation
of the generation seed of the game and YYYYYYYY is the hexadecimal
representation of the date of the game. This sorts the savegames by game and
then by date making it easier to find the right savegames.
When a desync has occurred with the desync debugging turned on you should file
a bug report with the following files attached:
- commands-out.log as it contains all the commands that were done
- the last saved savegame (search for the last line beginning with
'save: dmp_cmds_' in commands-out.log). We use this savegame to check
whether we can quickly reproduce the desync. Otherwise we will need...
- the first saved savegame (search for the first line beginning with 'save'
where the first part, up to the last underscore '_', is the same). We need
this savegame to be able to reproduce the bug when the last savegame is not
old enough. If you loaded a scenario or savegame you need to attach that.
- optionally you can attach the savegames from around 50%, 75%, 85%, 90% and
95% of the game's progression. We can use these savegames to speed up the
reproduction of the desync, but we should be able to reproduce these
savegames based on the first savegame and commands-out.log.
- in case you use any NewGRFs you should attach the ones you used unless
we can easily find them ourselves via e.g. grfcrawler or when they are
in the OpenTTDCoop pack.
Do NOT remove the dmp_cmds savegames of a desync you have reported until the
desync has been fixed; if you, by accident, send us the wrong savegames we
will not be able to reproduce the desync and thus will be unable to fix it.
3.0) Supported Platforms:
---- --------------------
OpenTTD has been ported to several platforms and operating systems. It shouldn't
be very difficult to port it to a new platform. The currently working platforms
are:
BeOS - SDL or Allegro
DOS - Allegro
FreeBSD - SDL
Linux - SDL or Allegro
MacOS X (universal) - Cocoa video and sound drivers (SDL works too, but not 100% and not as a universal binary)
MorphOS - SDL
OpenBSD - SDL
OS/2 - SDL
Windows - Win32 GDI (faster) or SDL or Allegro
4.0) Installing and running OpenTTD:
---- -------------------------------
Installing OpenTTD is fairly straightforward. Either you have downloaded an
archive which you have to extract to a directory where you want OpenTTD to
be installed, or you have downloaded an installer, which will automatically
extract OpenTTD in the given directory.
OpenTTD looks in multiple locations to find the required data files (described
in section 4.2). Installing any 3rd party files into a "shared" location has
the advantage that you only need to do this step once, rather than copying the
data files into all OpenTTD versions you have.
Savegames, screenshots, etc are saved relative to the config file (openttd.cfg)
currently being used. This means that if you use a config file in one of the
shared directories, savegames will reside in the save/ directory next to the
openttd.cfg file there.
If you want savegames and screenshots in the directory where the OpenTTD binary
resides, simply have your config file in that location. But if you remove this
config file, savegames will still be in this directory (see notes in section 4.2)
4.1) (Required) 3rd party files:
---- ---------------------------
Before you run OpenTTD, you need to put the game's datafiles into a data/
directory which can be located in various places addressed in the following
section.
As OpenTTD makes use of the original TTD artwork you will need the files listed
below, which you can find on a Transport Tycoon Deluxe CD-ROM.
The Windows installer optionally can copy these files from that CD-ROM.
List of the required files:
- sample.cat
- trg1r.grf
- trgcr.grf
- trghr.grf
- trgir.grf
- trgtr.grf
Alternatively you can use the TTD GRF files from the DOS version:
- TRG1.GRF
- TRGC.GRF
- TRGH.GRF
- TRGI.GRF
- TRGT.GRF
If you want the TTD music, copy the gm/ folder from the Windows version
of TTD to your OpenTTD folder (not your data folder - also explained in
the following sections).
Do NOT copy files included with OpenTTD into "shared" directories (explained in
the following sections) as sooner or later you will run into graphical glitches
when using other versions of the game.
4.2) OpenTTD directories
---- -------------------------------
The TTD artwork files listed in the section 4.1 "(Required) 3rd party files"
can be placed in a few different locations:
1. The current working directory (from where you started OpenTTD)
2. Your personal directory
Windows: C:\Documents and Settings\<username>\My Documents\OpenTTD
Mac OSX: ~/Documents/OpenTTD
Linux: ~/.openttd
3. The shared directory
Windows: C:\Documents and Settings\All Users\Documents\OpenTTD
Mac OSX: /Library/Application Support/OpenTTD
Linux: not available
4. The binary directory (where the OpenTTD executable is)
Windows: C:\Program Files\OpenTTD
Linux: /usr/games
5. The installation directory (Linux only)
Linux: /usr/share/games/openttd
6. The application bundle (Mac OSX only)
It includes the OTTD files (grf+lng) and it will work as long as they aren't touched
Notes:
- Linux in the previous list means .deb, but most paths should be similar for others.
- The previous search order is also used for newgrfs and openttd.cfg.
- If openttd.cfg is not found, then it will be created using the 2, 4, 1, 3, 5 order.
- Savegames will be relative to the config file only if there is no save/
directory in paths with higher priority than the config file path, but
autosaves and screenshots will always be relative to the config file.
The prefered setup:
Place 3rd party files in shared directory (or in personal directory if you don't
have write access on shared directory) and have your openttd.cfg config file in
personal directory (where the game will then also place savegames and screenshots).
4.3) Portable Installations (External Media):
---- ----------------------------------------
You can install OpenTTD on external media so you can take it with you, i.e.
using a USB key, or a USB HDD, etc.
Create a directory where you shall store the game in (i.e. OpenTTD/).
Copy the binary (OpenTTD.exe, OpenTTD.app, openttd, etc), data/ and your
openttd.cfg to this directory.
You can copy binaries for any operating system into this directory, which will
allow you to play the game on nearly any computer you can attach the external
media to.
As always - additional grf files are stored in the data/ dir (for details,
again, see section 4.1).
5.0) OpenTTD features:
---- -----------------
OpenTTD has a lot of features going beyond the original TTD emulation.
Unfortunately, there is currently no comprehensive list of features, but there
is a basic features list on the web, and some optional features can be
controlled through the Advanced Settings dialog. We also implement some
features known from TTDPatch (http://www.ttdpatch.net/).
Several important non-standard controls:
* Ctrl makes many commands more powerful. For example Ctrl clicking on signals
with the build signal tool changes their behaviour.
* Ingame console. More information at
http://wiki.openttd.org/index.php/Console
* Right clicking shows tooltips
5.1) Logging of potentially dangerous actions:
---- ----------------------------------------
OpenTTD is a complex program, and together with NewGRF, it may show a buggy
behaviour. But not only bugs in code can cause problems. There are several
ways to affect game state possibly resulting in program crash or multiplayer
desyncs.
Easier way would be to forbid all these unsafe actions, but that would affect
game usability for many players. We certainly do not want that.
However, we receive bugreports because of this. To reduce time spent with
solving these problems, these potentially unsafe actions are logged in
the savegame (including crash.sav). Log is stored in crash logs, too.
Information logged:
* Adding / removing / changing order of NewGRFs
* Changing NewGRF parameters, loading compatible NewGRF
* Changing game mode (scenario editor <-> normal game)
* Loading game saved in a different OTTD / TTDPatch / TTD version
* Running a modified OTTD build
* Changing settings affecting NewGRF behaviour (non-networksafe settings)
* Changing landscape (by cheat)
* Triggering NewGRF bugs
No personal information is stored.
You can show the gamelog by typing 'gamelog' in the console or by running
OpenTTD in debug mode.
6.0) Configuration File:
---- -------------------
The configuration file for OpenTTD (openttd.cfg) is in a simple Windows-like
.INI format. It's mostly undocumented. Almost all settings can be changed
ingame by using the 'Advanced Settings' window.
When you can not find openttd.cfg you should look in the directories as
described in section 4.2. If you do not have an openttd.cfg OpenTTD will
create one after closing.
7.0) Compiling:
---- ----------
Windows:
You need Microsoft Visual Studio .NET. Open the project file
and it should build automatically. In case you want to build with SDL support
you need to add WITH_SDL to the project settings.
PNG (WITH_PNG) and ZLIB (WITH_ZLIB) support is enabled by default. For these
to work you need their development files. For best results, download the
openttd-useful.zip file from SourceForge under the Files tab. Put the header
files into your compiler's include/ directory and the library (.lib) files
into the lib/ directory.
For more help with VS see docs/Readme_Windows_MSVC.txt.
You can also build it using the Makefile with MSYS/MinGW or Cygwin/MinGW.
Please read the Makefile for more information.
Solaris, FreeBSD, OpenBSD:
Use "gmake", but do a "./configure" before the first build.
Linux/Unix:
OpenTTD can be built with GNU "make". On non-GNU systems it's called "gmake".
However, for the first build one has to do a "./configure" first.
MacOS X:
Use "make" or Xcode (which will then call make for you)
This will give you a binary for your CPU type (PPC/Intel)
However, for the first build one has to do a "./configure" first.
To make a universal binary type "./configure --enabled-universal"
instead of "./configure".
BeOS:
Use "make", but do a "./configure" before the first build.
MorphOS:
Use "make". However, for the first build one has to do a "./configure" first.
Note that you need the MorphOS SDK, latest libnix updates (else C++ parts of
OpenTTD will not build) and the powersdl.library SDK. Optionally libz,
libpng and freetype2 developer files.
OS/2:
A comprehensive GNU build environment is required to build the OS/2 version.
See the docs/Readme_OS2.txt file for more information.
DOS:
A build environment with DJGPP is needed as well as libraries such as
Allegro, zlib and libpng, which all can be downloaded from the DJGPP
website. Compilation is straight forward: use make, but do a "./configure"
before the first build. The build binary will need cwsdpmi.exe to be in
the same directory as the openttd executable. cwsdpmi.exe can be found in
the os/dos subdirectory. If you compile with stripping turned on a binary
will be generated that does not need cwsdpmi.exe by adding the cswdstub.exe
to the created OpenTTD binary.
7.1) Required/optional libraries:
---- -------------------
The following libraries are used by OpenTTD for:
- libSDL/liballegro: hardware access (video, sound, mouse)
- zlib: (de)compressing of savegames
- libpng: making screenshots and loading heightmaps
- libfreetype: loading generic fonts and rendering them
- libfontconfig: searching for fonts, resolving font names to actual fonts
- libicu: handling of right-to-left scripts (e.g. Arabic and Persian)
OpenTTD does not require any of the libraries to be present, but without
zlib you cannot open most savegames or use the content downloading system.
Without libSDL/liballegro on non-Windows and non-MacOS X machines you have
no graphical user interface; you would be building a dedicated server.
8.0) Translating:
---- -------------------
See http://www.openttd.org/development for up-to-date information.
The use of the online Translator service, located at
http://translator.openttd.org/, is highly encouraged. For getting an account
simply follow the guidelines in the FAQ of the translator website.
If for some reason the website is down for a longer period of time, the
information below might be of help.
8.1) Guidelines:
---- -------------------
Here are some translation guidelines which you should follow closely.
* Please contact the development team before beginning the translation
process! This avoids double work, as someone else may have already
started translating to the same language.
8.2) Translation:
---- -------------------
So, now that you've notified the development team about your intention to
translate (You did, right? Of course you did.) you can pick up english.txt
(found in the SVN repository under /src/lang) and translate.
You must change the first two lines of the file appropriately:
##name English-Name-Of-Language
##ownname Native-Name-Of-Language
Note: Do not alter the following parts of the file:
* String identifiers (the first word on each line)
* Parts of the strings which are in curly braces (such as {STRING})
* Lines beginning with ## (such as ##id), other than the first two lines of
the file
8.3) Previewing:
---- -------------------
In order to view the translation in the game, you need to compile your language
file with the strgen utility. You can download the precompiled strgen from:
http://www.openttd.org/download-strgen
To compile it yourself just take the normal OpenTTD sources and build that.
During the build process the strgen utility will be made.
strgen is a command-line utility. It takes the language filename as parameter.
Example:
strgen lang/german.txt
This results in compiling german.txt and produces another file named german.lng.
Any missing strings are replaced with the English strings. Note that it looks
for english.txt in the lang subdirectory, which is where your language file
should also be.
That's all! You should now be able to select the language in the game options.
9.0) Troubleshooting
---- ---------------
To see all startup options available to you, start OpenTTD with the
"./openttd -h" option. This might help you tweak some of the settings.
If the game is acting strange and you feel adventurous you can try the
"-d [[<name>]=[<level>]" flag, where the higher levels will give you more
debugging output. The "name" variable can help you to display only some type of
debugging messages. This is mostly undocumented so best is to look in the
source code file debug.c for the various debugging types. For more information
look at http://wiki.openttd.org/index.php/Command_line.
The most frequent problem is missing data files. Don't forget to put all GRF
files from TTD into your data/ folder including sample.cat!
Under Windows 98 and lower it is impossible to use a dedicated server; it will
fail to start. Perhaps this is for the better because those OS's are not known
for their stability.
With the added support for font-based text selecting a non-latin language will
result in garbage (lots of '?') shown on screen. Please open your configuration
file and add a desired font for small/medium/-and large_font. This can be a font
name like "Tahoma" or a path to a font.
Any NewGRF file used in a game is stored inside the savegame and will refuse
to load if you don't have that grf file available. A list of missing files
will be output to the console at the moment, so use the '-d' flag (on windows)
to see this list. You just have to find the files (http://grfcrawler.tt-forums.net/)
put them in the data/ folder and you're set to go.
