CSC 8310 Prolog Assignment
Fall 2000, David Matuszek

Your assignment is to write an adventure game in SWI-Prolog. Pick any theme you like for your adventure game: rescue, survival, treasure hunt, "a day in the life," or whatever else appeals to you.

Your game should have between 5 and 10 rooms, and at least two "active" objects. But be creative! You cannot just replace the text descriptions and call it a new adventure game; that will get you a very poor grade. (Somebody tries this every time I give this assignment!) You must have a new room layout, a new set of actions, and new code that you have written yourself. This is a programming assignment, and you are expected to do some programming, not just replace text strings.

Here are two adventure games that you can use as a starting point for your own adventure game. Spider is the simpler game, so you should probably look at it first. Sleepy uses more complex logic, including not ( /+ ) and or ( ; ). You may copy and use some source code from the sample games; in particular, you probably want to take the code for picking up and dropping things, and for moving from place to place (take/1, drop/1, and go/1). But again, you are expected to write a reasonable amount of Prolog code of your own, not just change the object descriptions and room descriptions.

I'll ask for the following specifics:

• Two or more active objects with special "behaviors:" for example, a flashlight that only works when it has fresh batteries, a safe that has to be unlocked to get the contents, a vending machine, a time machine, a marker that you can use to write on room walls, etc. Things that you can maybe just pick up and drop, but that have no special properties or uses, do not count.
   
  
• One active object should begin with your first initial, and one with your last initial.. For example, if your name is John Smith, you might have "jar" and "spider" (for a household game), or "jellyfish" and "shark" (for an ocean adventure), or "jet" and "spacesuit" (for a space adventure).
   
  
• At least four new verbs specific to your game (for example, kill/0 in the spider game).
   
  
• Documentation that tells us about your special objects and your new verbs. If you don't point these out, we might not see them, and you won't get credit for them.
   
  
• A start/0 predicate that gives brief instructions, so that if we want to play your game, we know how to get started.

Grading will not be 100% objective. If we like your game, we may give you extra points for it. If your game seems to lack creativity and interest, you may lose points.

Please turn in:

• On paper: A listing of your source code.
• On paper: A transcript of a sample run of your program.
• On floppy: Source code in machine-readable form..
