ABSTRACT

"Brick Breaker" is a classic Android arcade game. The game is mainly based

and motivated from the game "Arkanoid" (released in 1986, developed by

Taito).

The game play is based on elementary physics i.e. reflection principle.

Brick Breaker (platformer) is a game in which the player must smash a wall of

bricks by deflecting a bouncing ball with a paddle. The paddle moves

horizontally and is controlled with Android Touch or the computer's touch

screen . When all the bricks have been destroyed, the player advances to a new

level. There are 5 levels with color-coded tiles and entertaining Creative

Common's Licensed music.

The game is considered PG5 due to stress levels and the concentration levels

required by the game.

INTRODUCTION TO UNITY ENGINE

Unity is a cross-platform game engine developed by Unity Technologies and

used to develop video games for PC, consoles, mobile devices and websites.

Unity Pro is available for a fee and Unity Personal has no fee; it is available for

any use to individuals or companies with less than US$100,000 of annual gross

revenue. On March 3, 2015 with the release of Unity 5.0, Unity Technologies

made the complete engine available for free including all features. Unity is

noted for an ability to target games to multiple platforms.

With an emphasis on portability, the engine targets the following APIs:

Direct3D on Windows and Xbox 360; OpenGL on Mac and Windows; OpenGL

ES on Android and iOS; and proprietary APIs on video game consoles. Unity

allows specification of texture compression and resolution settings for each

platform the game engine supports, render-to-texture and full-screen post-

processing effects.

The game engine's scripting is built on Mono, the open-source implementation

of the .NET Framework. Programmers can use UnityScript (a custom language

with ECMAScript-inspired syntax, referred to as JavaScript by the software) or

C#.

Unity is notable for its ability to target games to multiple platforms. Within a

project, developers have control over delivery to mobile devices, web browsers,

desktops, and consoles.

INTRODUCTION TO ANDROID PLATFORMER

Android is a mobile operating system (OS) currently developed by Google,

based on the Linux kernel and designed primarily for touchscreen mobile

devices such as smartphones and tablets. Android's user interface is based on

direct manipulation, using touch gestures that loosely correspond to real-world

actions, such as swiping, tapping and pinching, to manipulate on-screen objects,

along with a virtual keyboard for text input. As of 2015, Android has the largest

installed base of all operating systems.

Android is Open-Source (courtesy Google Inc.) with huge community and tech

support which make it among the best platforms to work upon. Android SDK

2.0 is the current official version released by Google for making Android

Application Development easier for Developers throughout the globe.

INTRODUCTION TO BRICK BREAKER

"Brick Breaker" is a classic Android arcade game.

The game play is based on elementary physics i.e. reflection principle.

Brick Breaker (platformer) is a game in which the player must smash a wall of

bricks by deflecting a bouncing ball with a paddle. The paddle moves

horizontally and is controlled with Android Touch or the computer's touch

screen . When all the bricks have been destroyed, the player advances to a new

level. There are 5 levels with color-coded tiles and entertaining Creative

Common's Licensed music.

The game is fun to play, Open Source (courtesy Developers) and has a childish

element to it.

GAME THEME

9 | P a g e

THE GENERAL UI

The game UI has a very elegant and sophisticated feel with very simple layouts and textures and interesting background music, and smooth working buttons. The game becomes fun to play.

10 | P a g e

LEVELS

The game levels have been thoughtfully designed considering the difficulty level after thorough surveys which adds to the game experience. The levels have color coded bricks with following color codes.

BLUE -- 1 HIT -- 10 POINTS

GREEN -- 2 HIT -- 20 POINTS

YELLOW -- 3 HIT -- 35 POINTS

RED -- 4 HIT -- 50 POINTS

When the player taps in the center of the screen, the ball takes flight. On tapping either side of the screen the paddle moves in the corresponding direction.

11 | P a g e

CONCLUSION

The game produces output as expected for inputs.

The paddle moves in the direction corresponding to the touch.

The ball launches when the screen is tapped.

The bricks get destroyed as expected.

The player score is incrementing based upon the brick destroyed.

Levels progress upon completion.

Game loss screen is displayed after a loss of 3 lives.

APPENDIX A1

MOTIVATION

In the start of this wonderful experience, we actually planned to develop

an E-commerce Application. The idea was dropped later because we

thought it was too mainstream, then we finalized the quizzing App, that

idea was too dropped because of small audience and less exposure.

Finally we choose, the Brick Breaker.

APPENDIX A2

CHALLENGES, PROBLEMS AND SOLUTIONS

The challenges we faced were designing the Sprites i.e the game

components such as paddle, bricks, balls, etc. Another challenge was

learning nVidia physx2D which included colliders. Next challenge was

understanding FPS (Frames Per Second) and touch movements. Content

Designing was another thing we had to think upon because it is the crux

of the game. Lastly, we knew that Android Studio would be a poor choice

for coding the game due to limited interfacing and in-built functions.

The problems we faced during the development stage and the best

solution we could find in the given time frame:-

1.) Choosing an suitable game engine amongst Unity, Unreal4,

CryEngine3 and learning them.

(Unity - fast, free and huge community)

2.)Choosing the best alternative among C#, JavaScript and Python

(C#)

3.)Learning the touch interface of a standard Android device for placing

the Sprites.

APPENDIX A3

UNITY

Unity Engine was developed by Unity Technologies Ltd. for proving a platform to all the aspiring game developers. The tutorials available online guided us through the process of creating a basic game.

The class TouchManager is the header class which is implemented in the touchMovements and has the following aspects - TouchBegan, TouchEnded, TouchMoved, TouchStationary. With support of two fingers, the functions are implemented for the second finger as well. This part concludes the basic touch interface.

The classes playerScript, ballScript and blockScript are used with the paddle, ball and coloured bricks. The concept of preFabs is used to implented the basic content design which is inbuilt in unity Editor.

Finally the class Score is used to maintain the user score and the player Lives which are complimentary in the game start (3).

APPENDIX A4

C#

C# is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed by Microsoft within its .NET initiative and later approved. C# is one of the programming languages designed for the Common Language Infrastructure.

Unity provides the option of using C# or JavaScript. C# is a smoother and easier alternative due to its similarities with Java.

C# need not be learned separately for Unity provides users with extensive guides on Demand.
