Assignment 5: 60 points

In this assignment you will make a copy of the Raven project and
modify it so that the three robots exhibit different behaviors.  Here
are some behaviors you can try; you only need three of them.

1. One robot can do the behavior presently built in the Raven project.

2. One robot can chose as target the nearest sensed robot that is
facing in its direction.  It won't attack another robot that is not
poised to attack it.

3. One robot will keep account of how many times another robot has hit
it.  It will then choose the sensed robot that is closest and that hit
it the most times.

4. One robot will keep a record of how much damage another robot does
to it.  It will then choose the nearest sensed robot that has caused
the most damage.

5.  One robot can be a sharp shooter robot. It will take longer before
shooting (because it is taking careful aim) and does not add any
randomness to its aim (so it is more likely to hit its target).

In behaviors 3 and 4, you will modify MemoryRecord to have a field to
hold the new numbers (number of hits from the sensed robot or the
total amount of damage done by that robot) being saved about the
sensed robot described by that record.

The default IDs for the three robots are 401, 402 and 403. When you
modify code, you will look up the robot's ID and then execute the
code you write for that robot.  You will want to turn on the score
display (on General Bot Info menu, click on Show Scores) to see how
many robots each robot kills.  You want to find out which behavior is
most effective.

Turn in a copy of the modified code you wrote.  Identify which
behavior each robot is doing and try to rank the three you implement
in order of effectiveness. Also turn in a screen shot in which the
robot IDs and scores are shown.  Don't show the Goal Queue or Health.
Let the game run a while before taking the screen shot so that the
scores indicate the effectiveness of each robot.
