Question About Data Types

[Brian]

Hi!

I am new to VB.net but know enough to kind of dive in. I want to make a text
adventure but I am having problems in how I want to store the data for
inventory items, characters and such. Right now, I have three rooms but a
lot of if and then statements on how to tell if they should appear in your
(listboxes) inventory or items in room box.

Any suggestions on where to store this information? Here is a sample of my
code:

Public Class Form1

Inherits System.Windows.Forms.Form

Dim lecroneLivingRoom As New room()

Dim lecroneKitchen As New room()

Dim lecroneDen As New room()

Dim wigwam As New items()

Dim television As New items()

Dim atari As New items()

Dim locale As String

#Region " Windows Form Designer generated code "

Public Sub New()

MyBase.New()

'This call is required by the Windows Form Designer.

InitializeComponent()

'Add any initialization after the InitializeComponent() call

End Sub

'Form overrides dispose to clean up the component list.

Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

If disposing Then

If Not (components Is Nothing) Then

components.Dispose()

End If

End If

MyBase.Dispose(disposing)

End Sub

Private components As System.ComponentModel.IContainer

Hi Brian,

As far as I understand what you want, I think I would use a XML dataset in
this case.

I asume it is a standalone application.

[Brian]

Hmmm...interesting..I've done the same with some web site menus...I will see
what I can do.

Hi Brian... Sounds like a fun project for you but before you get too far
down this road I'll mention that you are on the wrong track :-)

Start to think of your "adventure world" as a physical place like your own
house. The code you posted has it set up as a "form" which has some objects
scattered around it like rooms and applicances and stuff. You aren't
"moving from room to room" you are clicking on the form and having the form
tell the user stuff. You see the difference?

Consider creating a single "Adventure World" Class that contains rooms
(another class) which contain objects (another class). But don't stop
there. Your LivingRoom, Den and Kitchen are all the same... you have them
described as "rooms" when in fact they should be subclassed from room. Your
LivingRoom should be a class that describes the LivingRoom, a Den class
describes a Den, etc. The television, atari game and such should similarly
contain their own data and have their own methods so the AdventureWorld (and
the UI) can interact with them.

Clicking the eastBtn for instance wouldn't have a bunch of IF or SELECT CASE
statements hoping to keep track of everything but rather it would simply
communicate the "move east one unit" to the player object in the
AdventureWorld object. The UI could ask the player object what it sees or
it can ask the LivingRoom object for a list of items in the room, etc.

In any case... think of it as a model of the real world (to begin with) it
isn't the real world of course but start with that line of thinking. The UI
simply interacts with that world, it doesn't "describe" it or decide what is
in each room.

OK..I will print your message, study and dive in! ;)

I am new to VB.net but know enough to kind of dive in. I want to make a text

adventure but I am having problems in how I want to store the data for
inventory items, characters and such. Right now, I have three rooms but a lot of if and then statements on how to tell if they should appear in your (listboxes) inventory or items in room box.

Any suggestions on where to store this information? Here is a sample of my code:

Hi Brian... Sounds like a fun project for you but before you get too far
down this road I'll mention that you are on the wrong track :-)

Start to think of your "adventure world" as a physical place like your own
house. The code you posted has it set up as a "form" which has some

objects scattered around it like rooms and applicances and stuff. You aren't
"moving from room to room" you are clicking on the form and having the form tell the user stuff. You see the difference?

Consider creating a single "Adventure World" Class that contains rooms
(another class) which contain objects (another class). But don't stop
there. Your LivingRoom, Den and Kitchen are all the same... you have them
described as "rooms" when in fact they should be subclassed from room. Your LivingRoom should be a class that describes the LivingRoom, a Den class
describes a Den, etc. The television, atari game and such should similarly contain their own data and have their own methods so the AdventureWorld (and the UI) can interact with them.

Clicking the eastBtn for instance wouldn't have a bunch of IF or SELECT CASE statements hoping to keep track of everything but rather it would simply
communicate the "move east one unit" to the player object in the
AdventureWorld object. The UI could ask the player object what it sees or
it can ask the LivingRoom object for a list of items in the room, etc.

In any case... think of it as a model of the real world (to begin with) it
isn't the real world of course but start with that line of thinking. The UI simply interacts with that world, it doesn't "describe" it or decide what is in each room.

Tom..can you e-mail me at the address on this posting? I have a few more
questions if you don't mind.

Tom..questions again...

What is the easiest way to more from room to room and keep inventory items
or show ones I've not picked up? Can I do all of this in classes? If so,
could you give me an example?

I do see endless code for buttons (like east, west, etc) the more the game
grows. I get a feeling, from your original post, that there is an easier way
to do this.

Thanks,
Brian

Hi Brian, in answer to your other posting... I'd prefer to avoid an email
exchange on text adventure game design (unless it's for hire) so let's keep
posting here :-)

What is the easiest way to more from room to room and keep inventory items
or show ones I've not picked up? Can I do all of this in classes? If so,
could you give me an example?
You have to do it all in classes... even if you just wrote 100 unrelated
functions and procedures they are part of a class, just a poorly conceived
one. That's why I think writing this could turn out to be a good exercise
for you. And, I don't know what the optimal solution would be but consider
that you would minimally require:

a RoomClass
a RoomCollectionClass
a PlayerClass

a RoomClass would contain properties that decided it should have. So let's
say it could contain various objects, let's call it furniture since naming
them "objects" might get confusing, you'd need

a FurnitureClass
a FurnitureCollectionClass

and the RoomClass would have a property of type FurnitureCollectionClass
which would contain the furniture for that room.

If your player entered a room and the player object had a reference to the
room it was in then you could conceivably output a list of things in the
room by iterating through the collection printing the description (in the
Furniture object.)

objPlayer.GetRoom().GetFurniture.Item(0).Descripti on

If it was something that could be picked up by the player (you would
essentially be keeping a reference to the thing in a collection of things
the player had. You would need to add a collection to the PlayerClass to
hold on to Furniture objects. (Furniture isn't a good name obviously.)
When the player picked up the object it would be removed from the room's
collection of furniture objects and added to the player's collection of
furniture objects.

To display what the player had you would iterate through its collection:

objPlayer.GetFurniture(0).Description

Moving from room to room depends upon (I guess) whether you only move in and
out of room or whether you can move around within the room. If you can
navigate around the room it sounds like you might need to implement a grid
system to keep track of the coordinates. That would complicate it of course
but the furniture could be placed somewhere specifically and not just be "in
the room."

Are you planning on giving the Player object omni-directional view? That is
can they see everything just by entering? Or must they turn to face the
wall in order to see the picture on the wall? Granted it isn't going to be
easy using an OOP methodology but it would surely be harder using strictly
procedural code.
I do see endless code for buttons (like east, west, etc) the more the game
grows. I get a feeling, from your original post, that there is an easier way to do this.

The "trick" is that the game must be able to be played without any GUI at
all. If you write it such that you can control the player, the rooms, the
furniture in the rooms, etc. by addressing the objects you've created
(through the debugger for instance) then you can add a UI surface to the
game after it is working.

Don't start by adding code to the EastButton_Click event hander. You know
that will make the player move east... that's easy. What happens in the
AdventureWorld model when the player moves east? That's the hard part and
that's the game. Not the GUI interface to the game. The same thing would
happen inside AdventureWorld if the user typed "move east" into a text box
and pressed "Enter." You don't want to find yourself cutting the code from
EastButton_Click and pasting it into TextCommand_Changed because you wanted
to test out a new method of moving the player around.

Not to belabor the point but consider... if it is all made up of classes of
objects how easy you can introduce a new feature. Let's say you decided
that "weight" was something you want to know about so you could send the
message "it's too heavy to lift." You would add Weight as a property of the
furniture class (obviously assigning each furniture object a weight) you
would add a MaxWeight property to the player class representing the total
weight of items he can carry.

You add some code to the Player's PickUpFurniture() method to test whether
this object plus the weight of the objects the player is already carrying
exceeds that player's MaxWeight. You haven't wandered around the UI looking
for the PickUpButton_Click event in order to add another select case
statement.

In any case... if I were you I'd hang around or search the game development
websites/newsgroups. Even if you choose to write your version in VB.Net it
doesn't mean that reading Basic, C or Pascal coded solutions would hurt.
Search out the concepts and translate them into VB.Net.

Hope this helps... and have fun.
Tom

Thanks again..this is making sense finally but I am still a little stuck on
how to make a button command refer to a class room. I don't mind having a
class for each room and item and such but just don't know how to make the
actions refer to them. I know using a variable like currentLocation would be
useful.

Brian I don't know your background or experience with OOP but before you try
to write anything complicated you need to familiarize yourself with the
basics. Create a few classes. Understand inheritance and containment.
Create private properties and public accessors. Instantiate a few objects,
interact with them... figure out where you would have to instantiate one in
an app in order to have any button in your UI interact with the object.

If you do it right you won't have a "variable like currentLocation" anywhere
in the UI. The player object isn't in the UI, it is in AdventureWorld. If
there was no UI at all the player would still be a part of AdventureWorld.
:-) The UI can't suddenly be responsible for remembering where the player
is. If it is going to do that it may as well remember where the lamp and
desk is and everything else also. You're back to writing spaghetti code.
I still think you need to read something or start coding "something" just to
get a handle on it... but, consider creating a single class, name it
AdventureWorld. Then in your application (the UI) declare an AdventureWorld
property (name it AW) and instantiate it when the form loads.

Now go back and add one property to the AdventureWorld class, something like
"Name" and have it return AdventureWorld. Go back the UI app and in a
button click event have it output AW.Name. If you see "AdventureWorld"
you're communicating to the object. From them on you add more things to the
world and you interact with them the same way.

At no point (in the UI) do you suddenly start creating variables to hold
onto items the player is carrying or the score or the elapsed time. Put
these things into the AdventureWorld class, it will keep track of
everything. If you need to know the score or the player's name or how long
you've been playing you will ask the AdventureWorld object that you've named
AW. For instance:

AW.Player.Name("Brian") ' should set the player's name
AW.Player.Name ' should return the player's name
