Concurrent Pacman

Concurrent Pacman is a game simulation developed at Aveiro University in the course 42593-Object-oriented Concurrent Programming for academic purposes in order to demonstrate concurrency in a object oriented language. Other goals of the project is to use Design by Contract (DbC) in Java.

This project has the following dependencies (included):

• GBoard: a DbC Graphical Console Board
• DbC Concurrency Library: a DbC java concurrent library replacement that replaces checked exceptions to unchecked

How to run

This simulation has 5 operating modes in order to test race conditions. The source root must be same as the folder resources that contains game elements. Help is available when no switch is specified.

$ ls
pacman  resources
$ java -ea pacman.Game

A zip containing a jar and the resources is also available at the releases section. Unzip and run as follow:

java -ea -jar Pacman.jar

Mode 1

Normal game in which pacman has 3 lives for pacman, 4 ghosts. Game ends when pacman has no more lives left or when all points (238) are collected. Bonus duration is 5 seconds.

java -ea pacman.Game 1

Mode 2

Aggressive mode. Pacman has 100 lives with 16 ghosts. Bonus duration increases to 15 seconds.

java -ea pacman.Game 2

Mode 3

Endless mode: infinite lives that doesn't end when all points are collected.

java -ea pacman.Game 3

Mode 4

Crazy mode. inifinite live, 32 pacmans and 32 ghosts running. Also infinite pacman lives so the game is endless.

java -ea pacman.Game 4

Mode 5

This mode is intended to stress-test thread termination and race conditions. 128 pacmans (threads) killing one ghost

java -ea pacman.Game 5

Bugs

For some reason Java may not be running with opengl acceleration and graphical frame rate can drop. In order to force acceleration run the simulation with -Dsun.java2d.opengl=True flag, for example:

java -ea -Dsun.java2d.opengl=True pacman.Game 5
