This folder contains Logtalk versions of some simple Prolog text adventures:

• nani_search, written by Amzi! inc
• sleepy, written by David Matuszek, Villanova University
• spider, written by David Matuszek, Villanova University
• wumpus, written by Dan Cliburn, University of the Pacific For the "nani_search" adventure, I applied the necessary changes to ensure compatibility with the backend Prolog compilers that you can use with Logtalk. The original code was also reformatted to comply with coding guidelines.

  For the "sleepy" and "spider" adventures, I applied the necessary changes to ensure compatibility with the backend Prolog compilers that you can use with Logtalk, rewrote some code to avoid creation of choice-points, and added a very simple command-line interface.

  For the "wumpus" adventure, I applied the necessary changes to ensure compatibility with all the backend Prolog compilers that you can use with Logtalk.

  Any bugs introduced while adapting these text adventure examples to Logtalk are solely my responsibility.

  There is no support for restarting a text adventure. If you want to play again, you must restart your Logtalk session and load the example again.
