OpenTTD comes without AIs, so if you want to play with AIs you have to download

them. The easiest way is via the "Check Online Content" button in the main menu.

You can select some AIs that you think are compatible with your playing style.

Another way is manually downloading the AIs from the forum although then you

need to make sure that you install all the required AI libraries too; they get

automatically selected (and downloaded) if you get the AIs via the "Check

Online Content". If you do not have an AI but have configured OpenTTD to start

an AI a message will be shown that the 'dummy' AI has been started.

4.1) (Required) 3rd party files

---- --------------------------

directory which can be located in various places addressed in the following

section.

For OpenTTD you need to acquire some third party data files. For this you have

the choice of using the original Transport Tycoon Deluxe data files or a set

of free data files.

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.

4.1.1) Free graphics and sound files

not matter whether you copy them from the DOS or Windows version of Transport

Tycoon Deluxe. The Windows install can optionally copy these files.

You need to copy the following files:

 - sample.cat

 - trg1r.grf or TRG1.GRF

 - trgcr.grf or TRGC.GRF

 - trghr.grf or TRGH.GRF

 - trgir.grf or TRGI.GRF

 - trgtr.grf or TRGT.GRF

4.1.3) Original Transport Tycoon Deluxe music

------ --------------------------------------

4.1.4) AIs

------ ---

If you want AIs use the in-game content downloader. If for some reason that is

not possible or you want to use an AI that has not been uploaded to the content

download system download the tar file and place it in the ai/ directory. If the

AI needs libraries you'll have to download those too and put them in the

ai/library/ directory. All AIs and AI Libraries that have been uploaded to

the content download system can be found at http://noai.openttd.org/downloads/

The AIs and libraries can be found their in the form of .tar.gz packages.

OpenTTD can read inside tar files but it does not extract .tar.gz files by

itself.

		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 OpenTTD files (grf+lng) and it will work as long as they aren't

		touched

Different types of data or extensions go into different subdirectories of the chosen main

OpenTTD directory:

	Config File:         (no subdirectory)

	Screenshots:         (no subdirectory)

	AIs:                 ai                      (or a subdirectory thereof)

	AI Libraries:        ai/libraries            (or a subdirectory thereof)

	Savegames:           save

	Automatic Savegames: save/autosave

	Scenarios:           scenario

The (automatically created) directory content_download is for OpenTTD's internal use and

no files should be added to it or its subdirectories manually.

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.

	  autosaves and screenshots will always be relative to the config file.

The preferred 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 (portable 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/).

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.

again, see section 4.1).

5.0) OpenTTD features

---- ----------------

OpenTTD has a lot of features going beyond the original Transport Tycoon Deluxe

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:

	small_font = "Tahoma"

	medium_font = "Tahoma"

	large_font = "Tahoma"

You should use a font name like "Tahoma" or a path to the desired font.

Any NewGRF file used in a game is stored inside the savegame and will refuse

to load if you don't have that NewGRF file available. A list of missing files

can be viewed in the NewGRF window accessible from the file load dialogue window.

You can try to obtain the missing files from that NewGRF dialogue or - if they

are not available online - you can search manually through our forum's graphics

development section (http://www.tt-forums.net/viewforum.php?f=66) or GrfCrawler

(see section 4.2 "OpenTTD directories") and rescan the list of available NewGRFs.

Once you have all missing files, you are set to go.
