COMP 424: Code description
Pentago-Twist
Project TAs: Erfan Seyedsalehi and Samin Yeasar
Overview
An implementation of Pentago-twist (follow the link:
Player games requires: a server (the real board) to be launched, and then two clients (agents) to connect to the server
via TCP sockets; this allows for clients to be run on separate computers. We also provide a GUI which displays the
game in a nice and intuitive way for learning the strategy behind Pentago-twist. Note that games between agents can
be played without the GUI to increase speed. All source code is found in the src directory. You must NOT edit any
packages, other than stu- dent player, which can be modified as much as you want so long as it (1) compiles, and, (2)
that you do not use any external libraries, but you can use default internal Java libraries (like Math and Util). If you
edit other packages you must be aware that your edits will not be used during the tournament; e.g., so if you know
what you’re doing, you may want to edit Autoplay.java to run many test games of your agent against another agent (or
perhaps against itself).

Coding tips
The PentagoBoardState (PBS) you are given to work with in your ChooseMove method is a copy of the real PBS,
so you can modify it without worrying about changing the real PBS. However, you should clone the PBS and then
process moves on the cloned PBS to assess the impact of doing different moves on the PBS; note that a cloned PBS
that processed a move can also be cloned again.
Work flow: Eclipse
We recommend that you develop your agent using Eclipse to avoid complication to compile and run the project. You
can also use IntelliJ, which also provides very easy way to run java project. The root directory of the project package
is a valid Eclipse project. There are two ways to get it running, based on the following clicks:
2
• From GitHub: File → Import → Git → Projects from Git → Clone URI !→ put in field URI https://github.com/SaminYeasar/pentago -
twist → keep pressing Next until the end!
• From source: File → Import → General → Existing projects into workspace and then select the root of the
project package.
You may need to set the launch configurations manually as follows: File → Import → Run/Debug → Launch configurations
and then navigate to the eclipse directory and select those launches.
Note: GitHub is a great tool for managing your project. However, if you choose to use it, please set the project access
to private - this is free for students.
Quick Start Pentago-Twist with Eclipse
If using Eclipse and you’ve set it up as described above, you can easily start a game. Simply click Run in Eclipse,
then click on GUI. This will launch the GUI for you. Then, click the launch tab in the GUI, and select Launch Server.
Then, the first client you launch will be the first player; for example, select Launch Human Player next. Then, to set the
second player, select the next client class; for example, select Launch Client (pentago twist.RandomPentagoPlayer).
You can now play against a random player in the GUI to get a feel for the game. Changing the Clients you select will
determine who/what plays who/what - so you can run two humans against each other too, and similarly two agents
against each other.
Playing Games
Here we provide documentation for the server and client programs. The commands outlined in this section are the
commands that are called by the provided build.xml file (if using ant) and launch configurations (if using Eclipse).
The details provided in this section are especially useful for advanced use of the provided code, such as playing games
where the clients are located on different machines than the server. All of these commands assume that you have
compiled the code and stored the class files in a directory named bin located inside the root directory of the project
package (Eclipse will automatically do these things). In a nutshell, if you want to run from the command line, you
will need three terminal shells open and simultaneously running: one to launch the server, one to launch a Client for
the first player, and one to launch a Client for the second player.
Launching the Server
To start the server from the root folder of the project package, run the command:
java -cp bin boardgame.Server [-p port] [-ng] [-q] [-t n] [-ft n] [-k] (1)
where:
• (-p) port sets the TCP port to listen on. (default=8123)
• (-ng) suppresses display of the GUI
• (-q) indicates not to dump log to console.
• (-t n) sets the timeout to n milliseconds. (default=2000)
• (-ft n) sets the first move timeout to n milliseconds. (default=30000)
• (-k) launch a new server every time a game ends (used to run multiple games without the GUI)
For example, assuming the current directory is the root directory of the project package, the command:
java -cp bin boardgame.Server -p 8123 -t 300000 (2)
3
launches a server on port 8123 (the default TCP port) with the GUI displayed and a timeout of 300 seconds. The
server waits for two clients to connect. Closing the GUI window will not terminate the server; the server exits once
the game is finished. If the -k arg was passed, then a new server starts up and waits for connections as soon as the
previous one exits. Log files for each game are automatically written to the logs subdirectory. The log file for a game
contains a list of all moves, names of the two players that participated, and other parameters. The server also maintains
a file, outcomes.txt, which stores a summary of all game results. At present this consists of the integer game sequence
number, the name of each player, the color and name of the winning player, the number of moves, and the name of the
log file.
Launching a Client
As stated previously, the server waits for two client players to connect before starting the game. If using the GUI, one
can launch clients (which will run on the same machine as the server) from the Launch menu. This starts a regular
client running in a background thread, which plays using the selected player class. In order to play a game of Pentagotwist
using the GUI, choose Launch human player from the Launch menu (as described in Section 4). Clients can also
be launched from the command line. From the root directory of the project package, run the command:
java -cp bin boardgame.Client [playerClass [serverName [serverPort]]] (3)
where:
• playerClass is the player to be run (default=pentago twist.RandomPentagoPlayer)
• serverName is the server address (default=localhost)
• serverPort is the port number (default=8123)
For example, the command:
java -cp bin boardgame.Client pentago twist.RandomPentagoPlayer localhost 8123 (4)
launches a client containing the random Pentago-twist player, connecting to a server on the local machine using the
default TCP port. The game starts immediately once two clients are connected. The two approaches of launching
players from the GUI and launching players from the command line can also be combined. For instance, one can
use the GUI to manually play against the random player (or any other agent) by first launching a human player using
the GUI, and subsequently launching the random player, either by selecting it in the GUI or running the appropriate
command from the command line. The order can also be switched; the player that connects to the server first will
move first.
Autoplay
The provided Autoplay script can be used to play a large batch of games between two agents automatically. It launches
a Server with the options -k -ng, and then repeatedly launches pairs of agents to play against one another. To use
Autoplay, run the following command from the root directory of the project package:
java -cp bin autoplay.Autoplay n games (5)
where n games is a positive integer number of games to play. The default behaviour of Autoplay is to play the student
agent against the random player, with the random player agent going first every second game. You can modify this
behaviour by editing Autoplay.java.

Implementing a Player
New agents are created by extending the class pentago twist.PentagoPlayer. The skeleton for a new agent is provided
by the class student player.StudentPlayer, and you should proceed by directly modifying that file. In implementing
your agent, you have two primary responsibilities:
1. Change the constructor of the StudentPlayer class so that it calls super with your student number.
2. Change the code in the method chooseMove to implement your agent’s strategy for choosing moves (the real
work).
To launch your agent from the command line, run the command:
java -cp bin boardgame.Client student player.StudentPlayer (6)
You can also launch your agent by selecting it from the Launch menu in the GUI. The project specification has further
details on implementing your player, and, in particular, what you need to submit.
