<p class="commentary firstcommentary"><a id="SP8" class="paragraph-anchor"></a><b>§8. </b>Darkness behaves, for room description purposes, a little as if it were a
|
|
room in its own right. Until the 1990s that was almost always how darkness
|
|
was implemented in IF programs: this persists in I6, but not I7, where the

|
existence of a room-which-is-not-a-room would break type safety.

<p class="commentary firstcommentary"><a id="SP12" class="paragraph-anchor"></a><b>§12. </b>The supplying activities are linguistically interesting, for reasons gone
|
|
into in the paper "Interactive Fiction, Natural Language and Semantic
|
|
Analysis": English verbs do not naturally seem to feature optional nouns.
|
|
Indeed, we say "it rained on Tuesday" where "it" refers to nothing at all,
|
|
merely because we can't bring ourselves to leave a gap and say just "rained
|
|
on Tuesday". A better example here would be "it sounded like rain", because
|
|
we do the same to convey the idea of listening ambiently rather than to
|
|
any single thing: listening appears to be rare among actions in that it can
|
|
equally well take a noun as not. Just as English handles this problem by
|
|
supplying a spurious "it" which appears to mean "the world at large",
|
|
so Inform handles it by supplying the current location, with the same idea
|
|
in mind. And the same applies to the sense of smell, which can be similarly
|
|
defocused.

<p class="commentary firstcommentary"><a id="SP19" class="paragraph-anchor"></a><b>§19. </b>That clears away the underbrush and reduces us to two matching tasks: (i)
|
|
to print the question, (ii) to parse the answer, given that we want to be
|
|
able to vary the set of choices available.
|
|
</p>
|
|
|
|
<p class="commentary">We do this by reading the options from the Table of Final Question Options.
|
|
(See below for its default contents.) Each row is an option, whose wording
|
|
must be placed in the topic column. The final question wording entry can
|
|
either be text describing the option — e.g., "perform a RESTART" — or
|
|
can be left blank, making the option a secret one, omitted from the question
|
|
but still recognised as an answer. The only if victorious entry can be set
|
|
to make the option available only after a victorious ending, not after a loss;
|
|
Infocom's traditional AMUSING option behaved thus. Finally, the table
|
|
specifies what to do if the option is taken: either it provides a rule,
|
|
or an activity to carry out. (If it provides only an activity, but that
|
|
activity is empty, then the option is omitted from the question and not
|
|
recognised as an answer.)

"locale" is a clutch of objects at a given level in the object tree. Most

then a single (though often, as here, multi-paragraph) locale:

items, especially those not yet picked up, followed by a paragraph which

lists the "nondescript" items — those not given paragraphs of their own,

such as the bucket and spade. (Some items, though — typically scenery,
|
|
but also for instance the player — are not even nondescript and do not

appear at all.) A locale can contain no interesting paragraphs, or no list

of nondescript items, or can even contain neither: that is, it can be

entirely empty.

<p class="commentary firstcommentary"><a id="SP23" class="paragraph-anchor"></a><b>§23. Locale Implementation. </b>When describing a locale, we keep a Table of interesting objects, each
|
|
associated with a priority — a number indicating how important, and
|
|
therefore how near to the top of the description, the object is. A special
|
|
syntax allows us to create the Table with exactly the same number of rows
|
|
as there are things in the model world: thus, in the worst case where
|
|
all things are in a single locale, we still will not run out of table
|
|
rows. (We do this rather than creating a large but fixed-size table
|
|
because memory is very short in some Z-machine I7 works, so we want to
|
|
take only what we might actually need. The table structure is not as
|
|
wasteful as it might look: an experiment with using a number property
|
|
of things instead showed that this table was actually more efficient,
|
|
because of the property numbering overhead in the Z-machine memory
|

representation of objects.)

<p class="commentary">We count the paragraphs printed in a global variable, not an activity variable,
|
|
since it needs to be consulted in sub-activities whose rules are outside what
|
|
would be its scope; that doesn't matter, though, since locale descriptions
|
|
are not nested. (If they were, the above table would fail in any case.)
|
|
</p>
|
|
|
|
<ul class="items"><li>(1) Disaster would ensue if the user tampered with the "initialise locale
|
|
description rule", but nobody is likely to do this other than intentionally.
|
|
</li><li>(2) The "find notable locale objects rule" in fact only runs a further
|
|
activity, the "choosing notable locale objects" activity. The task here
|
|
is to identify the objects which might by virtue of their location appear
|
|
in the locale, and to assign each of them a priority number.
|
|
</li><li>(3) The "interesting locale paragraphs rule" goes through all of the
|
|
notable objects chosen at stage (2), in order of priority, and offers each
|
|
to yet another activity: the "printing a locale paragraph about" activity.
|
|
This can either print a paragraph related to the item in question, or
|
|
demote it as being not even nondescript (by changing its priority to 0).
|
|
The default is to do nothing, in which case the item becomes nondescript.
|
|
</li><li>(4) The "you-can-also-see rule" prints what is, ordinarily, the final
|
|
paragraph of the locale description, listing the nondescript items. It
|
|
goes to some trouble to find out whether these all have a common object tree
|
|
parent, listing them with "list contents of" if they do: this is so that
|
|
people who have written rules such as "Rule for printing the name of the
|
|
blur while listing contents..." will take effect, because the "listing
|
|
contents" activity will be going on. Provided that the notable objects
|
|
chosen in (2) are all children of the locale domain, this will always
|
|
happen. If the user should add rules to make quite different objects also
|
|
notable, then the "you-can-also-see rule" has to resort to listing in
|
|
a way which doesn't use the "listing contents" activity — since the
|
|
list is not in fact a list of the contents of anything.

<p class="commentary firstcommentary"><a id="SP26" class="paragraph-anchor"></a><b>§26. Printing a Locale Paragraph. </b>By default there are four kinds of "interesting" locale paragraph, and
|
|
the following setup is fairly complicated because it implements conventions
|
|
gradually built up between 1978 and 2008.
|
|
</p>
|
|
|
|
<p class="commentary">To recap, this activity is run on each notable thing in turn, in priority
|
|
order. (It is only run on notable things for efficiency reasons.)
|
|
</p>
|
|
|
|
<p class="commentary">The basic principle is that, at every stage, we should consider an item
|
|
only if it is not "mentioned" already. This will happen if it has been
|
|
named by a previous paragraph, but also if it has been explicitly marked
|
|
as such to get rid of it. In considering an item, we have three basic
|
|
options:
|
|
</p>
|
|
|
|
<ul class="items"><li>(a) Print a paragraph about the item and mark it as mentioned — this
|
|
is good for interesting items deserving a paragraph of their own.
|
|
</li><li>(b) Print a paragraph, but do not mark it as mentioned — this is only
|
|
likely to be useful if we want to print information related to the
|
|
item without mentioning the thing itself. (For instance, if the presence
|
|
of a mysterious parcel resulted in a ticking noise, we could print a
|
|
paragraph about the ticking noise without mentioning the parcel, which
|
|
would then appear later.)
|
|
</li><li>(c) Mark the item as mentioned but print nothing — this gets rid of the
|
|
item, ensuring that it will not appear in the final "you can also see"
|
|
sentence, and will not be considered by subsequent rules.
|
|
</li><li>(d) Do nothing at all — the item then becomes "nondescript" and appears
|
|
in the final "you can also see" sentence, unless somebody else mentions
|
|
it in the mean time.
|
|
</li></ul>
|
|
<p class="commentary">Briefly, then, the following is the standard method:
|
|
</p>
|
|
|
|
<ul class="items"><li>(1) The "don't mention player's supporter in room descriptions rule"
|
|
excludes anything the player is directly or indirectly standing on or,
|
|
less frequently, in. The header of the room description has probably
|
|
already said something like "Boudoir (on the four-poster bed)", so
|
|
the player can't be unaware of this item.
|
|
</li><li>(2) The "don't mention scenery in room descriptions rule" excludes
|
|
scenery.
|
|
</li><li>(3) The "don't mention undescribed items in room descriptions rule"
|
|
excludes the player object. (It's redundant to say "You can also see
|
|
yourself here.") At present nothing else in I7 is "undescribed"
|
|
in this sense.
|
|
</li><li>(4) The "set pronouns from items in room descriptions rule" adjusts
|
|
the meaning of pronouns like IT and HER to pick up items mentioned.
|
|
Thus if a room description ends "Mme Tourmalet glares at you.", then
|
|
HER would be adjusted to mean Mme Tourmalet.
|
|
</li><li>(5) The "offer items to writing a paragraph about rule" gives the
|
|
"printing a paragraph about" activity a chance to intervene. We detect
|
|
whether it does intervene or not by looking to see if it has printed
|
|
any text.
|
|
</li><li>(6) The "use initial appearance in room descriptions rule" uses the
|
|
initial appearance property of an object which has never been handled
|
|
as a paragraph.
|
|
</li><li>(7) The "describe what's on scenery supporters in room descriptions rule"
|
|
is a somewhat controversial feature: whereas the rest of Inform's room
|
|
description conventions are generally consensus, this one is much
|
|
disliked by some users for its occasional inappropriateness. It prints
|
|
text such as "On the mantelpiece is a piece of chalk." for items which,
|
|
like the mantelpiece, are scenery mentioned (we assume) in the main
|
|
room description. (It is assumed that scenery supporters make their contents
|
|
more prominently visible than scenery containers, which we do not announce
|
|
the contents of.) The ability to modify, replace or abolish this rule was
|
|
one of the main motivations to break room description up into activities
|
|
in March 2008.
