In this tutorial you'll learn the basic concepts of rule-based programming, where rules are used to specify the logic of what must be accomplished, but an inference engine determines when rules are applied. You'll incrementally create a fully functional text adventure game, and in the process, learn how to write, organize, debug, test, and deploy CLIPS code.
Gary Riley was a member of the CLIPS development team while working for NASA at the Johnson Space Space Center from 1985 to 1996. Since leaving NASA, he has continued developing and maintaining CLIPS as public domain software.
