2
! The Inform Designer's Manual (16May97) includes various references to a
3
! sample game called "Ruins", which unfortunately is not supplied with the
4
! compiler. This file attempts to knit together several of the fragments from
5
! the DM into a small but complete game, intended primarily as an example for
6
! novices of a typical way to use Inform features, and as a starting point
9
! In order to keep the game manageably small, the following references from
10
! the DM have been omitted:
11
! parrot, low mist, chasm, pumice-stone ball, glyphs, dictionary,
12
! food rations, sodium lamp, cage.
13
! Other items have been changed as necessary for simplicity and consistency.
15
! Object definitions explicitly state the name of their parent object (if
16
! appropriate), rather than using the "->" construct.
18
! Once you've played the game and (hopefully) understood how it works, you
19
! are strongly encouraged to try modifying or extending it. For instance:
20
! - add the low mist in the Forest and Square_Chamber. In the DM it smells of
21
! broth, so perhaps you should provide a source for the smell (or just
22
! change the description)?
23
! - implement the parrot, perhaps having it fly into the Forest once the plane
25
! - extend the number of rooms. There's a suggestion that you could Down from
26
! the Shrine, or perhaps you could add a dark passage leading West from the
28
! - if the passage is dark, perhaps a lamp would be useful?
29
! - if you've got a lamp, the maze in the Web becomes much less daunting
30
! (and the descriptions will need beefing up too). So perhaps it's the lamp
31
! rather than the bangle which you find on your exit from the darkened Web?
32
! - the DM is a bit unclear about the role(!) of the pumice-stone ball, but
33
! it seems to need pushing into the chasm. Maybe it blocks the gap and
34
! allows you to cross to the other side (in order to reach the bangle)?
35
! - there are a couple of daemons in the example, but no timer. How about
36
! extending the Honeycomb so that if dropped it prints a warning and starts
37
! a timer causing itself to melt unless picked up again within two turns?
39
! Of course, it isn't worth spending too long on Ruins, since it's only a
40
! somewhat dull and well-visited example. As soon as you start to feel
41
! comfortable with the way that an Inform game is constructed...
43
! ...have a go at writing one of your own. Good luck!
