CHAPTER ONE
What is an adventure game?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This chapter is mainly for people who have never even seen an
adventure game before, so if you know all about adventures then
you may skip this chapter and read the following ones.
Adventure games come in different forms, they can be mouse or
keyboard controlled. Sac is a keyboard control creator.
There all loads of keyboard control adventure games in PD
librarys like "The elven crystals" for example. This type of
game plunges the player into a world of fantasy where anything
could happen and the computer would act upon the players command.
The standard text adventure would look something like this....
You are in a small clearing. The sun shines its glow upon the
flowers in a nearby field which stands to the north. To the
distance south is a small cottage with a nice garden and to the
west you can see the dark forest.
So this is what an adventure game is, Just a blank screen with
words on it. The computer acts as your eyes and ears and tells you
what you see and hear by displaying the words on the blank
screen. In the above example the computer is telling you that
you are in a small clearing and that you see a cottage and a
forest. This is called the location description and all adventures
are made up of these, a list of locations which
make up a game world.
Of course you will need a way of getting from one location to
another, so the locations are connected together which allows you
to move to that location by telling the computer to move you there.
Lets take a normal bedroom for this example, this could be the
first location in the adventure.
You are in your bedroom. Your posters hang on the wall and your
Hi-fi sits in the corner. The hallway is north.
As you can see, the first location is your bedroom and as the
nearest location is the hallway then this would be the second
location. The location description tells you that the hallway is
to the north, so how do we move to the hallway?
After the location description the computer will display an
input cursor, it will then wait for you to command it, so the
screen would look something like this......
You are in your bedroom. Your posters are on the wall and your
Hi-fi sits in a corner. The hallway is north.
>_
You command the computer by typing in your command, so to move
to the hallway you could type.....
>go north_
You would then press the return key and the computer would
display the hallways location description....
You are in the upstairs hallway. To the west is the bathroom and
some stairs lead down. To the south is your bedroom.
We have now been moved to the hallway and told where we are and
what we see. We can get to any location in the game by telling
the computer to move there by typing the directions in.
As we typed "go north" to go to the hallway we need to type "go
south" to get back to the bedroom. More details in chapter two.
Other Descriptions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The location description will always stay the same so we use other
descriptions which change and move about. These are objects and
messages. First lets have a look at objects. This are things
that can be picked up and used by the player in the game. For
example, a sword could be found at a location. If one is found
then the computer would say....
You can see a sword.
>_
So if you want to take the sword you would just type "get sword"
and the computer will take it and say...
Okay you have got the sword.
>_
By typing "i" and pressing return the computer will list the
objects you are carrying. The letter "i" stands for inventory.
You can move from location to location by just typing the first
letter of the required direction, for example typing the letter
"n" is the same as "go north", and "ne" is just the same as
typing "go north east"...etc...........
Now you have the object you may want to see what it looks like,
so you could type "examine sword" and the computer could say...
The sword is sharp with a golden hilt.
If the object is a piece of clothing then you could wear it by
typing "wear coat" or "remove coat" to take it off.
So if you wear the coat and then pressed "i" then the computer
would say something like..........
You have with you a coat (worn).
If you are carrying a lamp and it has been lit then the
inventory could say.... a lamp (lit).
If you wanted to get rid of the object then you would just type
"drop object" and it would stay at the present location.
More details on objects in chapter two
Messages
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
There are two types of message. Examine and Game. The Examine
messages print up when you examine an object as in the above
example. So typing "examine key" could print the message..
The key has some very small writing on it.
Game messages are ones that print up at all other times like..
There is a large dragon here.
Inside the jug is a key.
Game messages are also used when you examine part of the present
location. For example.......
>examine fireplace
A large fire burns proudly in it.
Here are the normal commands used in adventures...
Get- get an object from the present location.
Drop- drop an object at the present location.
Examine- examine a carried object or part of location.
i- lists objects that are carried or worn.
Quit- ends the game.
You can also group commands together like this......
>drop lamp and get sword then examine it_
Please note that any words or letters between two quotes "" are
to tell you what to type on the screen (user commands) so you
see something like "get sword" then you type it on the screen
without the quotes! (ie: get sword).
What is also important is that you must type any user commands
in lower case letters, not capitals else the game just won't
understand it at all.
So thats mainly what an adventure game is, a game that puts you
in a new world and leaves you to tell the computer what to do.
In order to make things a little bit clearer there is a sample
adventure game on this disk called ST BRIDES which was written
in one day using sac. In this game you play the part of a school
girl who is trapped in St brides school and the object of the
game is to find the doorkey and get out. There are plenty of
adventure games in the PD librarys to play which will enable you
to learn more about them. In fact I have put together a small
