Descartes says: first off... for those who have read the previous texts or for
those who were at previous classes, do you have any questions which have come
up since then?
Frog sighs
Kahless says: Not I..
Frog shakes his head
Grumpy shakes his head
Dagger shakes his head
Descartes says: naturally questions with respect to topics covered in those
classes?
Descartes says: well... for those who have not been involved with the classes
to date... here is how the work...
Bess appears from the shadows.
Bess has rejoined our reality.
Bess sighs
Descartes says: 1) go over any questions from previous classes... of which
there seem to be none
Descartes smiles at Bess
Descartes says: you missed nothing :)
Bess says: thanks :)
Frog looks over Bess
Descartes says: 2)  I will speak on a topic... today is detailed room building
Descartes says: 3) we will discuss anything on that topic... questions, ideas,
etc
Dagger looks at his surroundings.
Descartes says: 4) unreleated questions... stuff about what you are currently
doing with your areas
Descartes says: any questions before we start?
Frog shakes his head
Bess says: no, not yet
Descartes looks at his surroundings.
Grumpy says: nope
Dagger says: how long till new monster code comes out?
Descartes says: monster code will be done with the new combat... it will not
affect the way current monsters are coded... more on that later though
Dagger nods
Frog says: one quick question...
Frog says: can wandering monsters use add_action exits in new system?
Descartes says: yes?
Frog bows to Forlock
Dagger bows to Forlock
Descartes says: there will be a whole new idea behind the concept of monster
Kahless sighs
Grumpy smiles at Forlock
Descartes says: the short answer to your question is yes
Grumpy comforts Kahless sincerly
Descartes says: the long answer is that there are no such things as monsters,
blah blah blah
Frog says: oops.  i use add-actions to lock monsters within an area.
Descartes says: ok that is for the last section of class though :)
Frog nods
Descartes says: from the first class, we discussed ewhat made up any sort of
LPC object
Descartes says: we discussed how a room is not just room.c
Descartes says: a room is a container, so it has the properties of container.c
Descartes says: a container is an object, and tus inherits Object.c
Descartes says: and an Object needs cleaning up, so a room has the
functionality of clean_up.c
Descartes says: if you have not read the previous class transcript and you
were not at the previous classes, this may seem a bit nonsensical to ya
Descartes says: to do a quick review, for that reason, I will discuss
inheritance again a bit
Descartes says: and perhaps others may pick up something I did not discuss
before
Descartes says: and hopefully everyone can get a chance to read the
transcripts in detail and bring some questions to the next class
Descartes says: if the idle Nialson will post the transcripts :)
Descartes says: at any rate...
Descartes says: one of the central things about programming in LPC is the
ability to "inherit" the "functionality" of other objects
Descartes says: by functionality, I mean do the things that object is capable
of doing
Descartes says: by inherit, I mean that an object may have its own
functionality as well as that of the other object
Descartes says: hmm... let me step back a second...
Descartes says: who here does not fully 100% understand exactly what a
function is?
Descartes says: we should discuss that before anything else
Bess thinks she does...
Descartes says: thinks is not good enough then :) I would like you all to
REALLY understand before we go on :)
Bess smiles
Dagger only thinks too. :(
Forlock says: yeah it's the most important thing to grasp in all of LPC
Bess nods
Descartes says: LPC works by somethithing called a function call
Descartes says: a function is simply a set of things for the computer to do
which have been grouped together
Descartes says: generally the are grouped together to perform a single
"function"
Descartes says: for example, understand it or not, you have all seen the
function create()
Bess nods
Frog nods
Dagger nods
Descartes says: the purpose of create is to get an object created in the
memory of the computer
Descartes says: when you write that function create(), you are writing the
part of the function known as the definition
Descartes says: in other words, you are writing what create() does
Descartes says: create() basically is used in your objects to call other
functions
Descartes says: calling a function means starting the execution of the
definition of it
Descartes says: for example, if my create()  looks like this:
Descartes says: void create() { SetLong("What a thoughtful long!"); }
Descartes says: create() is defined to do one and only one thing
Descartes says: it simply starts the execution of another function called
SetLong()
Descartes says: when SetLong() is done, it reaches the end of create() and
terminates execution of create()
Descartes says: the order in which functions are defined in a file does not
matter
Descartes says: since a function is executed based on when it is called, not
on where it is
Descartes says: anyone have any questions so far?
Descartes says: by the way, I know a lot fo you are afraid to ask me questions
in general... but here ask ANYTHING, even if you think it is stupid
Frog shakes his head
Descartes says: I am here to help make this clear to you, and if it is not,
then I have not done this right and I need to know :)
Bess says: what would that command look like to a player?
Descartes says: well... the player does not really notice the creation of an
object
Descartes says: what happens behind the scenes is this....
Descartes says: I will use a room as an example
Descartes says: I am going to force you all to more a room really quick
Bess says: 	 know, so that would simply begin the process before
description..you would have to set attributes to the object next right?
Descartes says: cause the mortal here cannot ddo ith without help
Frog nods

Dagger looks at his surroundings.
Descartes says: sorry about the pause there.. trying to alias that last thing
to mmake you all more files :)
Descartes says: at any rate, if I understood your question right Bess, you
were right :)
Bess smiles
Descartes says: say that the room you see has not been touched by the driver
yet
Bess sees the light!
Descartes says: so the first play to enounter it is about to enter it
Bess looks at her surroundings.
Descartes says: the driver sees that the room as not yet been loaded into
memory
Descartes says: 1) it commits the program to memory
Descartes says: 2) then calls the function create() in that object to set it
up with initital valies
Descartes says: 3) then it resumes execution of the command (say "east") the
player typed that referenced the room
Descartes says: 4) that of course moves the player into the room
Descartes says: then the function init() in the room is executed by the driver
Descartes says: then the driver moves on to the command of another player
Descartes says: in the create of the room I just showed you...
Descartes says: does anyone need to see it again?
Descartes says: I seem to have ra,mbled on a bit :)
Dagger says:  I do please

}
Descartes says: create() begins to execute when the room is first loaded
Descartes says: the first thing that happens is ::create() is called and
executed... more on that one another time :)
Descartes says: then the function SetProperties() is called
Descartes says: this is a function that is defined inside your inheritance
chain
Descartes says: that one little line "inherit STD_ROOM"
Descartes says: has all the functions defined in the file room.c defined for
the object
Descartes says: one of the definitions you inherit is SetProperties()
Descartes says: SetProperties() does the following:
Descartes says: void SetProperties(mapping borg) { __Properties += borg; }
Descartes says: that means that whatever properties you defined are added on
to whatever properties might laready exist
Descartes says: and they are stored in the variable __Properties
