Assignment #3 - Due Feb 12th, 2003
-------------

For this homework you will implement a simple Finite State Machine to
control the behavior of a game character.

***
In order to do this, your CSUG lab account must be set up and GameX 
must be installed. We have provided complete instructions on how to 
do this on the Game Design web site at: 
	http://www.cs.cornell.edu/~rch8/courses/game490

GameX itself can be downloaded from the Gamex home page:

Using C++, create a class which implements a Finite State Machine.
Your class must have the following features:

1) It must load an array of ImageX images from TIF files stored
on disk. You can use the same mechanism that the Ship class does
in the ShipDemoX demo files.

2) You must maintain a current image member variable which is
an index into the image array. This variable will represent the
current image being display (out of the array of images), but >not< 
necessarily the current state of your Finite State Machine. 
(You will probably need another variable for the current state of 
your FSM)

3) You must provide a public member function 
called "void Draw (void)" which takes no parameters, has no 
return value, but uses the GameX draw functions to draw 
your "character" based on the current image variable.

4) The output of your program should be a GameX project in which 
a sprite "character" moves around or behaves in a way directed 
by a FSM. Your character should respond to internal behavior 
(that is, the FSM represents internal character AI) or possibly 
user input (using GameX). Note: More ambitious programmers can 
have their character respond to some other object or the 
environment as well. Implemented as seperate classes, of course.

You can have as many sprites in the sprite array as you would 
like. Although I would prefer if you created your own sprites 
using Photoshop (saving them as TIF files), feel free to use 
whatever sprites or images you want to. (Note: If you do create 
your own sprites, be sure to save them as TIF files with >no< LZW 
compression using Photoshop. Photoshop is available in the CIT lab 
in the basement of Upson)

If you are unfamiliar with C++, or have trouble compiling and 
linking, or have any questions about this assignment in general, 
first look at the ShipDemoX demo files for help or inspiration.
