|
||
! RUINS - an Inform example game, with answers to the exercises.
|
||
!==============================================================================!
|
||
! The Inform Designer's Manual (16May97) includes various references to a
|
||
! sample game called "Ruins", which unfortunately is not supplied with the
|
||
! compiler. This file attempts to knit together several of the fragments from
|
||
! the DM into a small but complete game, intended primarily as an example for
|
||
! novices of a typical way to use Inform features, and as a starting point
|
||
! for experimentation.
|
||
!
|
||
! In order to keep the game manageably small, the following references from
|
||
! the DM have been omitted:
|
||
! parrot, low mist, chasm, pumice-stone ball, glyphs, dictionary,
|
||
! food rations, sodium lamp, cage.
|
||
! Other items have been changed as necessary for simplicity and consistency.
|
||
!
|
||
! Object definitions explicitly state the name of their parent object (if
|
||
! appropriate), rather than using the "->" construct.
|
||
!
|
||
! Once you've played the game and (hopefully) understood how it works, you
|
||
! are strongly encouraged to try modifying or extending it. For instance:
|
||
! - add the low mist in the Forest and Square_Chamber. In the DM it smells of
|
||
! broth, so perhaps you should provide a source for the smell (or just
|
||
! change the description)? [EASY]
|
||
! - implement the parrot, perhaps having it fly into the Forest once the plane
|
||
! has departed? [EASY]
|
||
! - extend the number of rooms. There's a suggestion that you could Down from
|
||
! the Shrine, or perhaps you could add a dark passage leading West from the
|
||
! Corridor? [EASY/MIDDLING]
|
||
! - if the passage is dark, perhaps a lamp would be useful? [EASY]
|
||
! - if you've got a lamp, the maze in the Web becomes much less daunting.
|
||
! So perhaps it's the lamp rather than the bangle which you find on your
|
||
! exit from the darkened Web? [EASY]
|
||
! - there are a couple of daemons in the example, but no timer. How about
|
||
! extending the Honeycomb so that if dropped it starts a timer object
|
||
! causing itself to melt unless picked up again pretty quickly? [EASY]
|
||
! - a routine called SmartCantGo prints a helpful message if you try to move
|
||
! in an illegal direction. The routine, not in the standard library, is
|
||
! commonly Included from a separate file. Download the file from:
|
||
! ftp://ftp.gmd.de/if-archive/infocom/compilers/inform6/library/contributions/
|
||
! [EASY]
|
||
! - the DM is a bit unclear about the role(!) of the pumice-stone ball, but
|
||
! it seems to need pushing into the chasm. Maybe it blocks the gap and
|
||
! allows you to cross to the other side (in order to reach the bangle)?
|
||
! Maybe there's more to moving it than just one push? [MIDDLING/TRICKY]
|
||
! - finally, many games accept an XYZZY command (in tribute to the magic word
|
||
! in the original Adventure). Implement such a verb which transports the
|
||
! player to At_End_of_Road for one turn, then restores the original
|
||
! location (you can copy the room description from Advent.inf). [MIDDLING]
|
||
!
|
||
! You can find another version of this game, without answers to these
|
||
! exercises, in the file Ruins.inf.
|
||
!
|
||
! Of course, it isn't worth spending too long on Ruins, since it's only a
|
||
! somewhat dull and well-visited example. As soon as you start to feel
|
||
! comfortable with the way that an Inform game is constructed...
|
||
!
|
||
! ...have a go at writing one of your own. Good luck!
