Hull functions are configured in a file hullfunc.txt. This file is usually provided by the ship list designer as a part of the ship list. The hullfunc.txt file is a plain text file in a similar format as pconfig.src. PHost looks for this file first in the game directory, then in the root directory. If it did not find one, it uses built-in defaults compatible with the standard VGA Planets Host.
(4.0) Alternatively, hull functions can be set up in the section hullfunc of the file shiplist.txt, using the same format as described here. When PHost finds a shiplist.txt file, it will not use hullfunc.txt.
