Abstract
The software industry continues to evolve rapidly, expanding due to innovative new product
and service applications (apps), hardware platforms, delivery mechanisms and growing global
markets. Software Industry consists software development, game development, designing,
testing, quality assurance this sort of things .Games developers are involved in the creation and
production of games that range from computer, handheld, console and arcade games to games
on the internet, mobile phones and other wireless game applications. Their work involves
either design (including art and animation) or programming.
Games development is a fast-moving, multi-billion pound industry. The making of a game from
concept to finished product can take up to three years and involve teams of up to 200
professionals. There are many stages, including creating and designing a game’s look and how it
plays, animating characters and objects, creating audio, programming, localization, testing and
producing.
This Report is intended to give a complete overview of our Project the game “Ghost in the
Town” including the software requirement specification, working tools, features, playing
procedure , analysis model and overall description therein. This Report details all features upon
which we have currently decided with reference to the manner and importance of their
implementation. It’s important to illustrate that, this project shown as software project lab- II.

Chapter – 1: The Project Plan

6 | P a g e
This chapter covers the project proposal and feasibility of the proposal along with background
study, product and business perspective, the scopes and some preliminary idea of our game.
Gaming in the Field of Software Engineering
In the fast growing field of software engineering and development and even more rapidly
growing sector of game development the future is hard to predict. We are working with this
game as our software project lab-II.SPL-II is a 3 credit course and as part of our degree we
choose this type of work for doing better with development cycle, development period,
graphics, scripting, adopting new technology, animation.
In general software project is a project focusing on the creation of software. Consequently,
Success can be measured by taking a look at the resulting software.
In a game project, the product is a game. But and here comes the point: A game is much more
than just its software. It has to provide content to become enjoyable. Just like a web server:
without content the server is useless, and the quality cannot be measured. This has an
important effect on the game project as a whole. The software part of the project is not the
only one, and it must be considered in connection to all other parts: The environment of the
game, the story, characters, game plays, the artwork, and so on.

7 | P a g e
Background
Background is a set of events invented for a plot, presented as preceding and leading up to that
plot. It is a literary device of a narrative history all chronologically earlier than the narrative of
primary interest. In our project it’s a single player strategy game emphasizing logical thinking
and planning. They often stress resource and time management, which usually takes
precedence over fast action and character involvement. Tactical organization and execution are
necessary, and the game creators usually place the decision-making skills and delivery of
commands in the player’s hands.
1.1 The Project
It’s a complete strategy game with different levels. The main character of ‘Ghost in the Town’ is
a little ghost who loses its parents in a human neighborhood. The baby is afraid of people and
hasn’t adopted many ghost tricks yet. So it’s difficult for it to return to its parents. Now it must
find food and keep itself hidden in a crowded town. The main mission of the gamer is to use his
logic and save the ghost. There are several levels and in each level the gamer must hide the
ghost from people and feed it.
1.2 The Project Scope
This Report describes all the requirements for the project. The purpose of this research is to
provide a virtual image for the combination of both structured and unstructured information of
our project “Ghost in the Town”. “Ghost of the Town” is a single-player strategy game on the
Android platform. The player will progress through levels which require precise manipulation of
the environment, though the game Encourages creativity and daring via branching pathways.

8 | P a g e
The episodic structure of the game facilitates the pace of the story. We demonstrate the action
flow between input, script, display (output).We working mainly with story, levels, object,
animation, graphics, scripts, game engine facilities. We aren’t working with web launching, free
hand programming, carton making.

Chapter – 2: Software Requirement Specification
Section – 2.1: Introduction

10 | P a g e
2.1.1 Purpose
This Software Requirements Specification (SRS) part is intended to give a complete overview of
our Project the game “Ghost in the Town” including the action flow, initial user interface and
story therein. The SRS document details all features upon which we have currently decided with
reference to the manner and importance of their implementation.
2.1.2 Document Conventions
This document will freely interchange the pronoun “we” with the team’s acronym. As the
development team is responsible for the SRS document, no ambiguity arises from its usage.
There is a clear distinction, however, between the use of the words “player/gamer” and
“character.” The “player” is the human being interacting with the game in the real world, while
the “character” is the in-game player avatar being manipulated.
2.1.3 Intended Audience and Reading Suggestions
The SRS document also gives project managers a way to ensure the game’s adherence to our
original vision. Although the document may be read from front to back for a complete
understanding of the project, it was written in sections and hence can be read as such. For an
overview of the document and the project itself, see Overall Description. For a detailed
description of the game-play elements and their interaction with the character, read System
Features. Readers interested in the game-play interface and navigation between different
front-end menus should go through External Interface Requirements. Technical standards to
which the team will hold the project are laid out in Other Nonfunctional Requirements. The
development schedule, meanwhile, will be maintained in the Key Milestones.

11 | P a g e
2.1.4 Document Scope
This Software Requirements Specification (SRS) describes the functional and nonfunctional
requirements for the project. As we said before the purpose of this research is to provide a
virtual image for the combination of both structured and unstructured information of our
project “Ghost in the Town”.
Project “Ghost in the Town” was conceived by the 3 of our team members as having an
anticipated development cycle greater than the length of the semester. The team wishes to
carry on the project until its completion. The game will continue to grow until we feel it
satisfactory for open-source distribution.

Specification
Section – 2.2: General Description

13 | P a g e
2.2.1 Product and Business Perspective
Software product development is a paradigm shift from routine application maintenance and
support in the software industry. Development a game/software product from scratch is a
significant challenge for any organization. It requires considerable investments in terms of
effort and cost and also confirms client involvement, knowledge about client market (example:
Google play).
We have compiled some interesting articles from the web for you which should form the basis
for a concluding public discussion about the future of the game industry. Please feel free to
interrupt us any time and contribute your ideas. This will make our game much more lively and
interesting. Here this report product perspective describes the overall description.
2.2.2 System Environment
Gamer
Input Manager
(Key pad/game pad)
Script
(Compile)
Renders
(Display)

14 | P a g e
Gamer can interact with system by giving input (press key to start game) to the system. System
give those inputs to script, if any change occur (if the value is changed) this object send to
renders to display the things (a character can change its place).
2.2.3 Quality Function Deployment
Quality Function Deployment is a technique that translates the needs of the
customer into technical requirements for software/game. It concentrates on
maximizing customer satisfaction from the Software engineering process .With
respect to our project the following requirements are identified by a QFD.
o Normal Requirements.
o Expected Requirements.
o Exciting requirements.
Normal Requirements
Normal requirements consist of objectives and goals that are stated during the
meeting with the actor/gamer/relevant people. Normal requirements of our project
are:-
1. User friendly efficient and lucrative system.
2. Minimum maintenance cost (may be graphics definition).
3. Availability of expected requirements within the PC/mobile configuration.
4. Easy to operate.

15 | P a g e
5. They observe our game as this is build with professional manner.
6. The game with measured coding, professional thinking.
Expected Requirements
These requirements are implicit to the system and may be so fundamental that the
actor/gamer/ relevant people does not explicitly state them .Their absence will be a
cause for dissatisfaction.
1. Develop system within limited cost.
2. Maximum high definition.
3. Minimum hardware requirements which is relevant for this game.
4. Design whole system with efficient manner.
Exciting requirements
These requirements are for features that go beyond the customer's expectations and
prove to be very satisfying when present:
1. We may provide some cheat codes.
2. Maximum high regulation with minimum hardware.
3. We may provide an international player rank list.
4. Easy to update.

16 | P a g e
2.2.4 Usage Scenarios
First, gamer needs to download the game from our sponsor. After installation
he/she should read how to play and must see the initial “Story” provided by us. If
anyone takes the honey of our game then he feel the test and hopefully enjoy our
game. We provide also some typical options like “continue”, “score board”, “exit”
etc.
UX (user experience) is very important part of any software project/game. UX is a
broad term used to explain all aspects of a person’s experience with the system,
including the interface, graphics, industrial design, physical interaction, and the
manual. It’s essential that how much gamer can interact with our game.

17 | P a g e
Specification
Section – 2.3: Specific Requirements

18 | P a g e
2.3.1 External Interface Requirements
2.3.1.1 User Interfaces
Every game must has a menu so is can be user friendly enough and gamers can easily fulfill their
need. Menu is also an important thing while creating the SRS document section. In this SRS
document part; we have used the menu snapshots in the user manual part. These snapshots
are based on the menu of the game.
2.3.1.2 Hardware Interfaces
“Ghost in the town” is a mobile gaming application designed specifically for the Android
platform and is functional on both mobile smart phones and tablets. Gaming application data is
stored locally on the game engine elements. “Ghost in the town” has been developed for
Android developed Version and all subsequent releases. In the future we released in the
android platform. Now the Android platform is graphically adaptable with a 2 dimensional
graphics library and a 3 dimensional graphics library based on OpenGL ES 2.0 specifications as
well as hardware orientation, scaling, pixel format conversion and accelerated 3D graphics.

19 | P a g e
2.3.1.3 Software Interface
“Ghost in the town” has been developed using a series of game development tools.
Working tools and platform
 Unity3D
 Autodesk Maya
 Autodesk 3ds Max
 Android Software Development Kit (Android SDK): Software development kit for applications on
the Android platform. We want to release this game in the Android platform.
2.3.2 User Characteristics
There is one user all the time and the user always interact with the game (system) in different
manner.
So, Gamer is the only who communicate with the system through playing the game. The
Primary requirement is that Gamer must read the playing procedure provide by us
(developers).

2.4.2 Data Model
If software requirements include the need to create, extend or interface with database or if
complex data structures must be constructed and manipulated, the software team may choose
to create a data model as part of overall requirements modeling. As our game has many data
objects, we have chosen to create a data model which includes a E-R diagram and a data
schema.
Before going to the data model of “Ghost in the Town”, here is a generic data model for games

2.4.3 Behavioral Model
The Behavioral indicates how software will respond to external events or stimuli. There are two
ways to show these responses. One is state diagram and the other is sequence. Usually state
diagram came be made in two ways, one is creating a state diagram for each class and the
other is to create a state diagram of the whole system. As we don’t have any class, for this is
not an object oriented game, we have followed the later one. And to lessen complexity we have
divided the state diagram into two diagrams. On the other hand, for the sequence diagram, we
have created separate a sequence diagram for all the use cases if necessary.

Specification
Section – 2.5: Requirement Change Management

59 | P a g e
The developers intend to release a complete and fully functional game that follows the
guidelines mentioned in the SRS document. However, since the product will be released for
multiple Android platforms (i.e. the different phones running the Android system), updates will
likely be required. These updates would consist of any bug fixes that are necessary,
compatibility patches for all of the current phones that support the Android System, and
expansions of the content. If the players find any issues or has any comments they would be
able to contact the developers through the official support email address which is
ghostInTheTown_support@gmail.com.
2.5.1 Bugs and Glitches
The players would be able to contact the developers through the support email system. This is
where they would present any bugs or glitches they have detected and if they have any beliefs
that the game is not functioning properly. General concerns or comments would also need to
be submitted here.
CAE will check this email regularly in order to respond to any time sensitive information.
2.5.2 Patches
As the Android system is updated and new phones come out, the game would also need to be
updated. Developers would constantly be making changes in order to keep up with any
compatibility issues that may arise. These changes and any others that may be fixing bugs or
glitches would be released through these patches.

Chapter – 3: Design and Implementation

61 | P a g e
3.1 Product Design Terms
For every enterprise product two key terms of design is very important. They are:
 UX (User Experience)
 Backend Programming
3.1.2 User Experience (UX)
To avoid unnecessary product features, simplifying design documentation and customer-facing
technical public at, Incorporating business and marketing goals UX design is must.
User experience design (UXD or UED) is any aspects of a user's experience with a given system,
including the interface, graphics, industrial design, physical interaction, and the manual in most
cases,
User Experience Design fully encompasses traditional Human-Computer Interaction (HCI)
design, and extends it by addressing all aspects of a product or service as perceived by users.
UX stands for mainly relevant access of usability, accessibility and HCI.
UX defines user experience as “a person’s perceptions and responses that result from the use
or anticipated use of a product, system or service”.

62 | P a g e
3.1.2 Backend Programming
The "back end" is the code supporting that front end (responsible for database access, business
logic etc).
In simple term, application front end is what you see (i.e the user interface) and application
back end is the application engine that you do not see. The "back end" is the code supporting
that front end (responsible for database access, business logic etc).
Foe efficient implementation, to increase user acceptance both two are very important in
software industry.
3.2 System Features
I. CCTV Camera
II. Automatic Door
III. Title Screen
IV. Level Selection Menu
V. Pause Menu
VI. Option Menu
VII. Suspicion Meter
VIII. Flying
IX. Disguise
X. Dialogue on Tips

63 | P a g e
3.2.1 CCTV Camera
3.2.1.1 Description and Priority
CCTV Cameras are added in game Streets and other places in the game scene. The player needs
to be very careful so that the ghost child doesn’t get caught into the camera. If it is, the player
will lose the game.
3.2.1.2 Stimulus/Response Sequences
Step 1: The player notices the camera and checks the target area of camera.
Step 2: If player can survive from being camera target he can successfully leave the section.
Step 3: Otherwise, camera caught the ghost and game is finished.
3.2.1.3 Functional Requirements
REQ 1: Camera must change target area in a loop to catch ghost.
REQ 2: Camera must consistently update its current position.
REQ 3: If it catches the ghost in its area, it forces to abort the scene.
3.2.2 Automatic Doors
There are a few automatic doors in the scene .These doors open whenever the ghost comes
near to it.
Step 1: The ghost comes near to the door.
Step 2: Door opens automatically.

64 | P a g e
REQ 1: It must be continuously updated about the objects near it.
REQ 2: It must differentiate the ghost with other game object.
REQ 3: Whenever it feel ghost around it, must be opened.
3.2.3 Title Screen
The title screen is the screen the player will see every time upon playing the game. Through this
interface, the player can choose to start a new game, play from saved data, or adjust the
options. Since the title screen is the “hub” for all activities in the project, it must be included.
Step 1: The player launches the game from their portable device.
Step 2: The start screen loads and appears, prompting the player with three buttons: “Play
Game”, “Options”, and “Exit”.
Step 3: The player presses one of the buttons, triggering its respective function.
REQ-1: The title screen must load and appear every time the game is launched.
REQ-2: If the player quits the game during any stage of a level, they must be returned to the
title screen.
REQ-3: If the player presses the exit button, the game will end and return the player to the
phone’s regular interface.

65 | P a g e
REQ-4: If the player completes the game, the game will end and return the player to the title
screen.
3.2.4 Level Selection
The level selection screen is the primary way for the player to choose between different levels.
The game is separated into narrative chapters, inside of which are multiple levels. The hierarchy
holds true for the level select screen as well. Because this screen constitutes the player’s main
method of accessing the level database, it is essential to the game.
Step 1: Available chapters appear, as well as a “Return to Title Screen Option.”
Step 2: The player selects one of the chapters or returns to the title screen.
Step 3: If the player chooses a chapter, available levels within the chapter appear as well as an
option to return to the chapter view.
Step 4: The player selects one of the available levels or returns to the chapter view (Step 2.)
REQ-1: To unlock a chapter on the map screen, a player must complete the final non-bonus
stage in the previous chapter.
REQ-2: When a chapter is completed, the chapter’s bonus levels which have not been unlocked
become visible on the map screen in sequence with their respective non-bonus levels, but are
still inaccessible to the player.
REQ-3: Only chapters and levels which the player has unlocked are displayed on the level
selection screen, excepting those bonus levels falling under REQ-2.

66 | P a g e
3.2.5 Pause Menu
The player should be able to pause anytime during game-play, and this screen fulfills that
requirement. The pause menu also allows the player to navigate between game-play and the
level selection and title screens. The portable nature of the console renders player convenience
paramount, so this feature must be included.
Step 1: The player presses the pause button on the game-play interface.
Step 2: The level pauses, drawing up the pause menu which prompts the player with three
options: “Resume Game,” “Return to Map” and “Exit Game.”
Step 3: The player presses one of the buttons, triggering its respective function.
REQ-1: The “Return to Map” option must return the player to the chapter to which the exited
level belongs.
REQ-2: The “Resume Game” option must continue the game without any change to the
character’s vector or the state of the level from the moment of the pause action.

67 | P a g e
3.2.6 Option Menu
The options menu is accessible from the title screen and allows the player to configure controls
and graphical settings to suit his/her convenience. This screen is not essential to accessing
game-play and is hence of lower priority than the Title Screen or Pause Menu, but constitutes a
standard feature in commercial titles and is thus a desirable inclusion.
Step 1: The player accesses the options menu from the title screen. From here, the player
chooses to:
A) Select “On” or “Off” for “Sound”
B) Select “Left” or “Right” for “Controls”
C) Select “Return to Title Screen”
Step 2: The chosen options are written to the game and take effect immediately.
REQ1: Sound will be enabled when “On” is selected and disabled when “Off” is selected.
REQ2: The Sound will be set to “On” by default.
REQ3: Movement Scroll Bar will be set to the left side of the screen if “Left” is selected and set
to the right side of the screen if “Right” is selected.
REQ4: The Movement Scroll Bar is set to “Right” by default.
REQ5: Player will be directed back to the Title Screen when “Return to Title Screen” is selected.

68 | P a g e
3.2.7 Suspicious Meter
3.2.7.1 Descriptions and Priority
Suspicious will not be visible in the play screen. But it is a measurement of game score. The
more the player makes people suspicious the less is the score and so to get maximum stars in a
game scene the gamer must not raise suspicious among the civilians
Step 1: Ghost makes sound
Step 2: People suspicious
Step 3: Game score lessons
REQ 1: Store ghost actions during the game
REQ 2: Calculate stars depending on people suspicious
3.2.8 Flying
Introduced in higher level. As our ghost doesn’t have feet, user can say that he is actually flying
always. But this is not the thing we are intended to say by this flying feature. We will give the
play on a option to fly higher and hide from people in multistoried building.
Step 1: The player process the fly button.
Step 2: The ghost flies with a constant force.
Step 3: Player releases the button.

69 | P a g e
Step 4: Ghost falls.
REQ 1: Fly force should be standardized.
REQ 2: Levels should be adapted to this standard fly.
REQ 3: Flying should take into account the current vertical and horizontal velocities.
3.2.9 Disguise
Introduced in higher level (party scene). Ghost can disguise itself here by putting on a mask.
Step 1: Players comes to an interaction with a mask.
Step 2: Player selects the mask and put it on.
REQ 1: Mask must be ready and available to wear.
REQ 2: Levels should be adopted with disguise.
REQ 3: People must not recognize ghost with a mask.

70 | P a g e
3.2.10 Dialogue or Tips
Dialogue is the primary method by which the player will experience the game’s story. The
character’s guide carries on dialogue with the silent protagonist, providing context and
narrative. While this feature is secondary in importance to the primary game mechanics, it is an
important aspect of the game’s atmosphere and informs the level design and music to heighten
the player’s connection to the experience.
Step 1: The player passes a certain waypoint in a stage or completes a certain action.
Step 2: Dialogue is triggered and a text box or floating text pops up.
Step 3: To dismiss text boxes or continue reading multiple-page text boxes, the player clicks on
the text box or floating text area.
REQ-1: Dialogue should not pause the game to prevent player disorientation.
REQ-2: Text boxes and floating text should be brief and placed away from UI components so as
not to interfere with game-play.
REQ-3: The text must be readable from any device.

71 | P a g e
3.3 Assumptions and Dependencies
The final destination of our game's operation will be the Android mobile device. However, Unity
will be responsible for both the construction of the game and its integration within the Android
framework.
3.3.1 Construction of the Game
Unity includes many built-in components which will expedite the process of game development
immensely. These include:
o Physics Engine
o Collision Detection and Handling
o Input Recognition
o Object Creation and Transform Manipulation (position and rotation of game objects)
o Scene Integration (transition of one level to the next)
o Model Attachment (representing game objects with 3D models from external programs)

72 | P a g e
3.3.2 Integration with Android
Unity3D's build settings simplify the process of transferring our game to the Android mobile
device. After completing the project, or during any intermediary step for testing, we can select
Android from the list of options, build the project, and upload it to one of our own devices. A
separate license is required for this functionality, which has already been obtained by one of
the members of our group.

Chapter – 5: User Manual

80 | P a g e
5.1 Playing Procedure
Gamer first interact system UI to start playing. We provide playing tips to all users so that
he/she can easily understand about the playing procedure.
There are different levels in our game. Gamer can play each level by finishing the previous one.
Player uses his/her logic and maintains time to accomplish the game. He needs to feed the little
ghost to survive and take him out from the civilization. If gamer caught with baby ghost by
CCTV camera or any civilian, he loses the game. Here at the first level, gamers aim to be
communicating with the parents of the baby ghost. It can be through telephone or mobile
phone inside those civilians’ houses. Like that different level has different complexity and
different logic to finish. But the main thing is that gamer should survive with the child ghost
which is separated from its family.

 Take user response through website and produce web rank list
Conclusion
A software project means a lot of experience. In this section we summarize the experience
gained by project team during development of “Ghost in the Town”.
6.1 The Obstacles
1. Working with game engine completely a new experience for us. Normally we are working
with different OO languages, DBMS, mark up languages etc.
2. We adopt these things by video tutorials, text tutorials, internet and learning materials given
by the tools themselves. It's a matter of time, patience and hard work.
3. It is very sensible work and it demands much time because the game engines try to connect
game environment with the real world.
4. Creating a 3d model is very difficult because you need to work with each and every point of
the model.
5. The Exists game engines demands vast knowledge about its properties, sections and sub-
sections.
After all the thing is that a game project is not a project of 6 or 8 months for three people !

88 | P a g e
6.2 The Achievements
1. Now we know much more about game engines. How it works? The properties, objects and
others.
2. We know how a model is constructed and how it is animated.
3. The main thing is that as a software engineer, skill and expertise to create a SRS document
and a overall software product report is now better than before.
4. Co-Operation between group members.
5. Develop communication skills
6. Growing creative thinking and imagination capability .
6.3 Last Few Words
We learned a lot through this project. This project has sharpened our concept of Game engine,
animation and the software-hardware interface.
We learned a lot about different documentation. The piece of software we developed is
intended to serve the gamers of the world. The success of this project may give pleasure to
billions of game lovers among the universe. This project not only tested our technical skills but
also our temperament.
There were times that we almost lost hope but we recovered through constant concentration
and hard work.
If any kind of suggestion, improvements, more efficient development idea please feel free to
communicate with us.
