I express my gratitude to XXXXX for providing me the infrastructure to carry out

the project work and I would also like to thank all my classmates for their valuable

suggestions and helpful discussions.

World is contracting with the growth of mobile phone technology. As the number of

users is increasing day by day, facilities are also increasing. Starting with simple

regular handsets which were used just for making phone calls, mobiles have changed

our lives and have become part of it. Now they are not used just for making calls but

they have innumerable uses and can be used as a Camera , Music player, Tablet PC,

T.V. , Web browser, Games etc . Game development is an ever green and rapidly

growing market today, and therefore this is my attempt at developing a physics based

2D game.

ABSTRACT

The world is contracting with the growth of mobile phone technology. As the

number of users is increasing day by day, facilities are also increasing. Starting with

simple regular handsets which were used just for making phone calls, mobiles have

changed our lives and have become part of it. Now they are not used just for making

calls but they have innumerable uses and can be used as a Camera , Music player,

Tablet PC, T.V. , Web browser, Games etc . And with the new technologies, new

software and operating systems are required.

Operating Systems have developed a lot in last 15 years. Starting from black and

white phones to recent smart phones or mini computers, mobile OS has come far

away. Especially for smart phones, Mobile OS has greatly evolved from Palm OS in

1996 to Windows pocket PC in 2000 then to Blackberry OS and Android.

One of the most widely used mobile OS these days is ANDROID. Android is a

software bunch comprising not only of operating system but also middleware and

key applications. Android Inc was founded in Palo Alto of California, U.S. by Andy

Rubin, Rich miner, Nick sears and Chris White in 2003. Later Android Inc. was

acquired by Google in 2005. After original release there have been number of

updates in the original version of Android.

This Project is aimed at developing an Air Hockey game, and is built for the Android

OS. This game has been built in Java.

1: INTRODUCTION

1.1 PROJECT SUMMARY:

Project Title:

Air Hockey – 2D Physics Game

Problem Statement:

Create a 2D game which simulates the game of air hockey on an android device. The

software should be able to take uninterrupted inputs smoothly during the gameplay,

and hence should be highly optimized. The software should also have a player

running on Artificial Intelligence to serve as an opponent to the user. Scores should

be maintained and updated on each goal and results should be declared at the end of

the game.

Project Description:

The project deals with the task of designing a game by creating various algorithms.

These algorithms are responsible for various things like making possible the physics

emulation of the player in the game, for gesture recognition on the devices which

helps user to control the player, etc. The software will be able to increase the

difficulty of the levels as the user makes progress in the game.

Java is a programming language originally developed by Sun Microsystems and released in

1995 as a core component of Sun Microsystems' Java platform. The language derives much

of its syntax from C and C++ but has a simpler object model and fewer low-level facilities.

Java applications are typically compiled to bytecode that can run on any Java Virtual

Machine (JVM) regardless of computer architecture.

One characteristic of Java is platform independence, which means that programs written

in the Java language must run similarly on any supported hardware/operating-system

platform. One should be able to write a program once, compile it once, and run it anywhere.

This is achieved by compiling the Java language code, not to machine code but to Java

bytecode – instructions analogous to machine code but intended to be interpreted by a

virtual machine (VM) written specifically for the host hardware. End-users commonly use a

JRE installed on their own machine, or in a Web browser. Standardized libraries provide a

generic way to access host specific features such as graphics, threading and networking. In

some JVM versions, bytecode can be compiled to native code, either before or during

program execution, resulting in faster execution. A major benefit of using byte code is

portability.

1.2 INNOVATIVENESS:

Gaming industry is an evergreen and fast growing area in the world. Developing a

game not only tests the programming ability of the programmer, but also tests the

efficiency, creativity, and his ability to map the real world environment into the

software product he is developing. This project not only covers the programming

aspects, but also GUI (Graphical User Interface) designing

1.3 PROJECT SCOPE:

The game can be very helpful software for people who want to find a source of

entertainment, which is mobile. For full functionality, some modules of the game

may require network access on the device. Further, the game provides the single

player functionality and local multiplayer as well, and can be extended to online

multiplayer in the future.

1.4 TOOLS & TECHNOLOGIES USED:

The technologies that were used in the development of the game are as follows:

1.4.1 ANDENGINE

What is AndEngine?

AndEngine is a free 2D OpenGL game engine for the Android platform.

Along with the core engine, the platform supports extensions, such as the

following:

PhysicsBox2DExtension : Allows use of Box2D physics.

TMXTiledMapExtension : Allows reading of files generated in the

TMX Map Format.

TexturePackerExtension : Allows use of sprite sheets or sprite atlases

generated by TexturePacker.

MultiplayerExtension : Supports multiplayer

1.4.2 ECLIPSE

What is Eclipse?

In computer programming, Eclipse is an Integrated development environment

(IDE) comprising a base workspace and an extensible plug-in system for

customizing the environment. It is written mostly in Java. It can be used to

develop applications in Java and, by means of various plug-ins, other

programming languages including Ada, C, C++, COBOL, Fortran, Haskell,

JavaScript, Lasso, Perl, PHP, Python, R, Ruby (including Ruby on Rails

framework), Scala, Clojure, Groovy, Scheme, and Erlang. It can also be used

to develop packages for the software Mathematica. Development

environments include the Eclipse Java development tools (JDT) for Java and

Scala, Eclipse CDT for C/C++ and Eclipse PDT for PHP, among others.

1.4.3 PHOTOSHOP

What is Photoshop?

Adobe Photoshop is a graphics editing program developed and published by

Adobe Systems. Adobe's 2003 "Creative Suite" rebranding led to Adobe

Photoshop 8's renaming to Adobe Photoshop CS. Thus, Adobe Photoshop

CS6 is the 13th major release of Adobe Photoshop. The CS rebranding also

resulted in Adobe offering numerous software packages containing multiple

Adobe programs for a reduced price. Adobe Photoshop is released in two

editions: Adobe Photoshop, and Adobe Photoshop Extended, with the

Extended having extra 3D image creation, motion graphics editing, and

advanced image analysis features. Adobe Photoshop Extended is included in

all of Adobe's Creative Suite offerings except Design Standard, which

includes the Adobe Photoshop edition.

1.4.4 ANDROID SDK

Android applications are usually developed in the Java programming

language using the Android Software Development Kit, but other

development tools are available. As of October 2012, more than 700,000

applications have been developed for Android, with over 25 billion

downloads.

5: FUTURE ENHANCEMENT

It can support online scoreboards.

It can be extended to online multiplayer matches.

The AI can be made more intelligent.

More power-ups can be made available in the game

6: CONCLUSION

From a proper analysis of positive points and constraints on the component, it

can be safely concluded that the product is an efficient GUI based

component.

This application is working properly and meeting to all user requirements.

After doing this project, I have learned many things and I would like to thank

all the concerned individuals who have contributed to my precious learning.

I have also understood the importance of naming conventions and coding

conventions in development process.

I am sure that I can perform better as I step up on the ladder of experience.
