			Modifying Turbo Sliders


  Almost everything can be modified by text or image files but note that 
if you make new cars or modify existing tracks or terrains, this can cause 
problems with network games if all players do not have the same 
modifications. You will also break your old existing track records if you 
make significant modifications to existing tracks or cars. (You can, however,
change graphics and sounds etc.)

  To learn how to make total conversions, read README-totalmod.txt.


SOUNDS

  The sounds subdirectory contains the game samples as WAVs. You
can  modify or replace them. In addition to this, every car can have 
a distinctive motor sound. 


CARS

  The cars for the game are defined in the cars directory. The
game automatically searches and parses all files ending with ".car".
See the cardef.car for the default car definitions and descriptions
of the various properties that can be changed. If you want to add
your own cars, create new car files, do not edit cardef.car.


DEFAULT GRAPHICS

  Default graphics of the game are defined in files named *-img.png 
in the data directory and they can be freely modified.


CUSTOM TRACKS AND GRAPHICS

  The idea is that tracks packets can be compiled so that the track
maker can either use the default tiles and terrains or define all by
oneself. A track header contains an Include line which defines 
a tiles file. One can specify a custom tile file and put it in the same
directory as the track or use the default, tiles.til. See 
data/tiles.til for the file format and more information. Try to invent
such tile, image and pattern file names that they won't collide with
the names that other people might invent.


USING YOUR OWN TILES

  The files tiles.til and terrains.ter in the data directory contain
information on how to create your own terrain and tile files.
If you have created your own tiles file and some png files that are 
used by your tiles, proceed as follows: Create a new track directory 
under the tracks directory. Copy your tiles file and the graphics files
to that directory. Then, start editing a new track in that directory:

  editor -tx 960 -ty 600 tracks/newdir/newtrack.trk

  Save this track and edit the track. Using some text editor (Notepad 
or something else), edit the "include tiles2.til" to something else
to include your own tiles file instead. Try to use file names that 
the others would not choose to minimize the possibility of colliding 
file names. Note that the tiles file and any image files it might use 
must be in the same directory as the track file. Save the track file, 
and from now on, when you open the new track with the editor, your own 
tiles are used:

  editor tracks/newdir/newtrack.trk

  NOTE: Only use file extensions trk, til and ter for data files and
basic image extensions (png, gif, jpg, jpeg) for images. Otherwise, 
the other people may not be able to automatically download the tracks 
from a server.

  It is also possible to include the whole ter or til file in the trk
file. Just add them before any tile additions. You cannot save the
track with the editor after this, though.
