<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>§1. Summary. </b>To review: an action is an impulse to do something by a person in the model
|
|
world. Commands such as DROP POTATO are converted into actions ("dropping
|
|
the Idaho potato"); sometimes they succeed, sometimes they fail. While
|
|
they run, the fairly complicated details are stored in a suite of I6
|
|
global variables such as <span class="extract"><span class="extract-syntax">actor</span></span>, <span class="extract"><span class="extract-syntax">noun</span></span>, <span class="extract"><span class="extract-syntax">inp1</span></span>, and so on (see
|
|
"OrderOfPlay.i6t" for details); the running of an action is mainly a
|
|
matter of processing many rulebooks, chief among them they "action processing
|
|
rules".
|
|
</p>
|
|
|
|
<p class="commentary">In general, actions can come from five different sources:
|
|
</p>
|
|
|
|
<ul class="items"><li>(i) As a result of parsing the player's command: there are actually two ways
|
|
this can happen, one if the command calls for a single action, and another
|
|
if it calls for a whole run of them (like TAKE ALL). See the rules in
|
|
"OrderOfPlay.i6t".
|
|
</li><li>(ii) From an I7 "try" phrase, in which case <span class="extract"><span class="extract-syntax">TryAction</span></span> is called.
|
|
</li><li>(iii) From an I6 angle-bracket-notation such as <span class="extract"><span class="extract-syntax"><Wait></span></span>, though this is a
|
|
syntax which is deprecated now, and is never normally used in I7. The I6
|
|
compiler converts such a syntax into a call to the <span class="extract"><span class="extract-syntax">R_Process</span></span> below.
|
|
</li><li>(iv) Through conversion of an existing action. For instance, "removing the
|
|
cup from the table" is converted in the Standard Rules to "taking the cup".
|
|
This is done via a routine called <span class="extract"><span class="extract-syntax">GVS_Convert</span></span>.
|
|
</li><li>(v) When a request is successful, the "carry out requested actions" rule
|
|
turns the original action — a request by the player, such as is produced
|
|
by CHOPIN, PLAY POLONAISE — into an action by the person asked, such as
|
|
"Chopin playing the Polonaise".
|
|
</li></ul>
|
|
<p class="commentary">Certain exceptional cases can arise for other reasons:
|
|
</p>
|
|
|
|
<ul class="items"><li>(vi) Implicit taking actions are generated by the "carrying requirements rule"
|
|
when the actor tries something which requires him to be holding an item which
|
|
he can see, but is not currently holding.
|
|
</li><li>(vii) A partial but intentionally incomplete form of the "looking" action is
|
|
generated when describing the new location at the end of a "going" action.
|
|
</li></ul>
|
|
<p class="commentary">In every case except (vii), the action is carried out by <span class="extract"><span class="extract-syntax">BeginAction</span></span>, the
|
|
single routine which unifies all of these approaches. Except the last one.
|
|
</p>
|
|
|
|
<p class="commentary">This segment of the template is divided into two: first, the I6 code needed
|
|
for (i) to (vii), the alternative ways for actions to begin; and secondly
|
|
the common machinery into which all actions eventually pass.
|
|
</p>
|
|
|
|
<p class="commentary firstcommentary"><a id="SP2" class="paragraph-anchor"></a><b>§2. Fake Actions. </b>Though sometimes useful for I6 coding tricks, fake actions — action numbers
|
|
not corresponding to any action, but different from those of valid actions,
|
|
and useable with a number of action syntaxes — are not conceptually present
|
|
in I7 source text. They can only really exist at the I6 level because I6 is
|
|
typeless; in I7 terms, there is no convenient kind of value which could
|
|
represent both actions and fake actions while protecting each from confusion
|
|
with the other.
|
|
</p>
|
|
|
|
<p class="commentary">The following fake actions from the I6 library have been dropped here:
|
|
<span class="extract"><span class="extract-syntax">##LetGo</span></span>, <span class="extract"><span class="extract-syntax">##Receive</span></span>, <span class="extract"><span class="extract-syntax">##ThrownAt</span></span>, <span class="extract"><span class="extract-syntax">##Prompt</span></span>, <span class="extract"><span class="extract-syntax">##Places</span></span>, <span class="extract"><span class="extract-syntax">##Objects</span></span>,
|
|
<span class="extract"><span class="extract-syntax">##Order</span></span>, <span class="extract"><span class="extract-syntax">##NotUnderstood</span></span>.

table of metadata about the actions. Since this is compiled by Inform, the

following structure can't be modified here without making matching changes

in Inform. <span class="extract"><span class="extract-syntax">ActionData</span></span> is an I6 <span class="extract"><span class="extract-syntax">table</span></span> containing a series of fixed-length

|
|
conventions as after a going action, and we don't quite want a looking
|
|
action fully to take place. We nevertheless want to be sure that the
|
|
action variables for looking exist, and in particular, we want to set the
|
|
"room-describing action" variable to the action which was prevailing
|
|
when the room description was called for. We also set "abbreviated form
|
|
allowed" to "true": when the ordinary looking action is running, this
|
|
is "false".
|
|
</p>
|
|
|
|
<p class="commentary">The actual description occurs during <span class="extract"><span class="extract-syntax">LookSub</span></span>, which is the specific
|
|
action processing stage for the "looking" action: thus, we use the
|
|
check, carry out, after and report rules as if we were "looking", but
|
|
are unaffected by before or instead rules.

|

<p class="commentary">Uniquely, this pseudo-action does not use <span class="extract"><span class="extract-syntax">BeginAction</span></span>: it works only
|
|
through the specific action processing rules, not the main action-processing
|
|
ones, though that is not easy to see from the code below because it is
|
|
hidden in the call to <span class="extract"><span class="extract-syntax">LookSub</span></span>. The <span class="extract"><span class="extract-syntax">-Sub</span></span> suffix is an I6 usage identifying
|
|
this as the routine to go along with the action <span class="extract"><span class="extract-syntax">##Look</span></span>, and so it is,
|
|
but it looks nothing like the <span class="extract"><span class="extract-syntax">LookSub</span></span> of the old I6 library. Inform compiles

arising from parsing (such actions do not arise through the "try" phrase,

unless by stored actions in which case this has all happened before and

doesn't need to be done again) — the parser places details of which words

make up the topic in the I6 global variables <span class="extract"><span class="extract-syntax">consult_words</span></span> and <span class="extract"><span class="extract-syntax">consult_from</span></span>.

difficult to arrange without I6 subterfuges.)

hindered by certain restrictions — it only records action/noun combinations,

print a stored action, for instance, or to print an action name value.
|

(For instance, printing an action name might result in "taking"; printing
|

a whole action might produce "Henry taking the grapefruit".)
