• Project Six
• CSE 397/497
• AI and Computer Games

2
Introduction to Poker Academy

• Bots for the Poker Academy software are written
  in Java
• We will use the Meerkat API to interact with the
  Poker Academy Software
• Links to everything you need are provided on the
  Project Web Page

3
Programming Your AI

• Implement the poker.Player interface, and
  over-ride the required methods.
• Build against the provided meerkat-api.jar
  library
• Create a jar file with your bot's classes.
• Create a player definition file

4
Some Classes You Should Know

• Player
• Your AI will inherit from Player
• It has three methods
• getAction()
• holeCards()
• init()

5
Player

• init(Preferences prefs)
• Loads preferences from .pd file
• getAction()
• When its your turn to act, this method is
  called. Think of it as your main body
• holeCards(Card c1, Card c2, int seat)
• Returns your two hole cards, and your location at
  the table

6
Card

• Contains functions such as getRank() and
  getSuit() for manipulating cards
• Defines a constants for every value and suit,
  such as TWO, SEVEN, KING, or SPADES
• Ex
• if (c1.getRank() gt Card.TEN c2.getRank() gt
  Card.TEN)
• if (c1.getSuit() c2.getSuit())
• return Action.raiseAction(toCall,
  gi.getBetSize())
• return Action.callAction(toCall)

7
Action

• Think of actions returned by getAction() as nodes
  in your FSM
• From SimpleBot.java
• if (gi.getStage() Holdem.PREFLOP)
• return preFlopAction()
• else
• return postFlopAction()

8
Some More Classes to Know

• GameInfo
• Contains information about the current game, such
  as pot size, stage of the game (pre-flop, flop,
  river, etc), and info about the other players
• Hand
• Stores up to 7 Card elements
• Once your cards are in a Hand, you can use the
  HandEvaluator class to do lots of statistical
  functions on them, such as getNumBetter(), which
  returns the number of hands better than your
  current hand

9
Creating Your .pd File

• The .pd file stores information about your bot.
  We use SimpleBot.pd as a guide
• All plug-ins must run through the following
  class
• PLAYER_CLASScom.biotools.poker.opponent.PlugInOpp
  onent
• put your bot's full class name here
• BOT_PLAYER_CLASSSimpleBot
• put the path to your jar file here (relative to
  PokiPoker.exe)
• PLAYER_JAR_FILEdata/bots/simpleBot.jar
• Your Bot's name
• PLAYER_NAMESimpleBot
• Your bot engine name
• AI_NAMESimpleBot

Creating Your .pd File (cont)

• Options for your Bot
• DEBUGtrue
• RANDOM_SEED31313
• ALWAYS_CALL_MODEfalse
