An Introduction on Robocode
The Brainchild of Matthew Nelson A software engineer in the Advanced
Technology, Internet Division at IBM A game that allows players to create and
control a robot in the Java programming language
The goal is to be the last robot standing while being the best scorer.
Simple to learn, difficult to master like chess.
Player must write a Java code that creates a robot that can:MoveShoot at other robotsScan for other robotsHit the walls and other robots
More Sophisticated TechniquesStatistical Analysis, Neural Networks
To help people in learning the Java program while enjoying the experience
To help people in learning programming concepts such as control statements, method declarations, inheritance and event handling.
To sharpen strategic skills For the excitement of competition For prices?
Body - Carries the gun with the radar on top.
Gun - Mounted on the body and is used for firing energy bullets.
Radar - Mounted on the gun and is used to scan for other robots when moved.
•Must be unique in a specific Robocode installation•Advised to be your initials
•Import necessary Robocode classes, including the type of robot you will be using•You can also import any relevant Java classes including the standard Java classes
java.awt.Color; java.util.Random; Event objects of MouseListener, etc.
•Extending the right class determines the features that your robot can have:
•JuniorRobot•Robot•AdvancedRobot•RateControlRobot•TeamRobot
Robot The Robot type where
most users start Like the JuniorRobot,
this class’ methods are blocking calls
Have getters and setters instead of public fields
AdvancedRobot Has non-blocking calls Support for custom
events Can write to the file
system
•Literally, the life of your robot•Majority of the code resides here•The body outside the loop is used to ready the robot, i.e. setting colors, positioning the robot, etc.•The body inside the loop is used for logic that is not dependent on any event and is supposed to be repeated, i.e. moving though the battlefield.
How to win a battle?
StatisticsTotal Score Survival ScoreLast Survivor Bonus Bullet Damage Bullet Damage BonusRam Damage Ram Damage Bonus **1sts, 2nds, 3rds
BreakdownSurvival Score
Each robot that's still alive scores 50 points every time another robot dies.
Last Survivor Bonus The last robot alive scores 10 additional
points for each robot that died before it.Bullet Damage
Robots score 1 point for each point of damage they do to enemies.
BreakdownBullet Damage Bonus
When a robot kills an enemy, it scores an additional 20% of all the damage it did to that enemy.
Ram Damage Robots score 2 points for each point of
damage they cause by ramming enemies.Ram Damage Bonus
When a robot kills an enemy by ramming, it scores an additional 30% of all the damage it did to that enemy.
BreakdownTotal Score
All statistics are added to obtain the total score. The total score will determine the rank of the robot in the battle.
Additional**1sts, 2nds, 3rds These do not actually contribute to
score. But they are shown to indicate how long
the robot survived. They also show the number of rounds the robot was placed 1st, 2nd, and 3rd.
How to win a battle?LAST ROBOT STANDING
The last surviving robot does not necessarily indicates the winner in a battle.
Reminder:The total score is computed by
adding the different statistics of the robot.Even if your robot survived because it
has more energy than the others, if it only saves energy and the other robots killed other robots, they will gain more points.
WallsMoves around the outer edge (wall)
with the gun facing inA simple robot (inherited from class Robot)
A tricky robot; usually lasts the longest in the battlefield with other sample robots
TargetSits stillMoves every time energy drops by 20An advanced robot (inherited from
class AdvancedRobot)
Target
SpinbotCharacteristics
Body Color: Blue Gun Color: Blue Radar Color: Black Scan Color: Yellow
Behavior Moves in a circle, firing hard when an
enemy is detected
SpinbotAdditional Info
Inherited from Advanced Robot Has a damage of 16 Has a maximum speed of 5(in pixels)
RamfireCharacteristics
Body Color: light Gray Gun Color: Gray Radar Color: Dark Gray
Behavior Drives at robots trying to ram them, fires
when it hits them.
RamfireAdditional Info
Inherited from Robot Has a damage from 4 - 16
Trackerbasically locks onto a robot, moves close
to it, then fires when close
Tracker
TrackFirea still robot.; it just tracks and fires at
the nearest robot it sees
