Package: adventure
This is a faithful port of the “Adventure” game to Python 3 from the
original 1977 FORTRAN code by Crowther and Woods (it is driven by the
sameadvent.datfile!) that lets you explore Colossal Cave, where
others have found fortunes in treasure and gold, though it is rumored
that some who enter are never seen again.This page:http://rickadams.org/adventure/e_downloads.htmloffers the original PHP source code at this link:http://www.ifarchive.org/if-archive/games/source/advent-original.tar.gzTo encourage the use of Python 3, the game is designed to be played
right at the Python prompt.  Single-word commands can be typed by
themselves, but two-word commands should be written as a function call
(since a two-word command would not be valid Python):>>> import adventure
>>> adventure.play()
WELCOME TO ADVENTURE!!  WOULD YOU LIKE INSTRUCTIONS?

>>> no
YOU ARE STANDING AT THE END OF A ROAD BEFORE A SMALL BRICK BUILDING.
AROUND YOU IS A FOREST.  A SMALL STREAM FLOWS OUT OF THE BUILDING AND
DOWN A GULLY.

>>> east
YOU ARE INSIDE A BUILDING, A WELL HOUSE FOR A LARGE SPRING.
THERE ARE SOME KEYS ON THE GROUND HERE.
THERE IS A SHINY BRASS LAMP NEARBY.
THERE IS FOOD HERE.
THERE IS A BOTTLE OF WATER HERE.

>>> get(lamp)
OK

>>> leave
YOU'RE AT END OF ROAD AGAIN.

>>> south
YOU ARE IN A VALLEY IN THE FOREST BESIDE A STREAM TUMBLING ALONG A
ROCKY BED.The original Adventure paid attention to only the first five letters of
each command, so a long command likeinventorycould simply be typed
asinven.  This package defines a symbol for both versions of every
long word, so you can type the long or short version as you please.You can save your game at any time by calling thesave()command
with a filename, and then can resume it later:>>> save('advent.save')
GAME SAVED

>>> adventure.resume('advent.save')
GAME RESTORED
>>> look
SORRY, BUT I AM NOT ALLOWED TO GIVE MORE DETAIL.  I WILL REPEAT THE
LONG DESCRIPTION OF YOUR LOCATION.
YOU ARE IN A VALLEY IN THE FOREST BESIDE A STREAM TUMBLING ALONG A
ROCKY BED.You can find two complete, working walkthroughs of the game in itstestsdirectory, which you can run using thediscovermodule that
comes built-in with Python 3:$ python3 -m unittest discover adventureI wrote most of this package over Christmas vacation 2010, to learn more
about the workings of the game that so enthralled me as a child; the
project also gave me practice writing Python 3.  I still forget the
parentheses when writingprint()if I am not paying attention.Traditional ModeYou can also use this package to play Adventure at a traditional prompt
that does not require its input to be valid Python.  Use your operating
system command line to run the package:$ python3 -m adventure
WELCOME TO ADVENTURE!!  WOULD YOU LIKE INSTRUCTIONS?

>At the prompt that will appear, two-word commands can simply be
separated by a space:> get lamp
OKFor extra authenticity, the output of the Adventure game in this mode is
typed to your screen at 1200 baud.  You will note that although this
prints the text faster than you can read it anyway, your experience of
the game will improve considerably, especially when a move results in a
surprise.Why is the game better at 1200 baud?  When a paragraph of text is
allowed to appear on the screen all at once, your eyes scan the entire
paragraph for important information, often ruining any surprises before
you can then settle down and read it from the beginning.  But at 1200
baud, you wind up reading the text in order as it appears, which unfolds
the narrative sequentially as the author of Adventure intended.If you created a file with the in-gamesavecommand, you can restore
it later by naming it on the command line:> save mygame
GAME SAVED
> quit
DO YOU REALLY WANT TO QUIT NOW?
> y
OK

$ python3 -m adventure mygame
GAME RESTORED
>NotesSeveral Adventure commands conflict with standard Python built-in
functions.  If you want to run the normal Python functionexit(),open(),quit(), orhelp(), then import thebuiltinmodule and run the copy of the function stored there.The word “break” is a Python keyword, so there was no possibility of
using it in the game.  Instead, use one of the two synonyms defined by
the PDP version of Adventure: “shatter” or “smash.”CopyrightTheadvent.datgame data file distributed with this Python package,

my source code from the FORTRAN source (the famous phrase “You have
gotten yourself killed” and so forth) remain public domain and can be
