Tutorial materials for Ceptre. You will need: a unix-based command line (e.g. Terminal on Mac OS X or Cygwin on Windows), libgmp on Linux or OS X, basic command line knowledge (tar, cp, mv, etc.), and a text editor for code.

Ceptre can be used to prototype or implement autonomous behavior for interactive stories or games. That autonomous behavior could be used for procedural content generation or for controlling non-player characters that the player interacts with.

Ceptre aims to hit a sweet spot between tools for generalized agent autonomy, such as planners, which have little support for designing interaction models; and interactive story authoring tools, such as Inform, which have little support for autonomy.

File: otp.cep.

Key idea: writing rules with multiset rewriting notation.

RANDOM FANDOM! Generate OTPs from a cast of characters.

File: quest.cep

Key idea: interacting with rules.

Exercises:

• Add a rule for opening something (e.g. the chest).
• Add a rule for taking something out of something (e.g. the map out of the chest) and moving it to the surrounding room.

File: quest-sim.cep

Key idea: using stages to separate interactive and autonomous behavior.

Exercise:

• Add a character-to-character interaction of your choosing.

File: quest-social.cep (or build on quest-sim.cep)

Key idea: writing backward-chaining rules and using predicates defined by them to check conditions, e.g. "Does C1 like C2 enough to give them an item that they want?"
