INTRODUCTION TO THE PROJECT

Our project is based on a game which is designed with some codes

using C-language. Programming is done to create a digital-based

visuals using COMPUTER GRAPHICS.


8/37

It is a simple game that shows a spaceship in space which shoots

digitally created enemy sapceships with digital BULLETS. It is

created using various techniques and functions supported in

graphics,such as- setcolor(),arc(),circle(),rectangle() etc.

To make it more interactive light effect and sound effects are also added

to the programming. For light effects setfillstyle(),floodfill() etc.

functions are used, and for audio sound() function is used.

The game can be played in a window sized screen which continuously

shows the playing screen. Several functions can be performed such asmoving the spaceship wherever on the screen as we move the MOUSE

POINTER .The bullets are fired wiht the use of left click.One bullet for

each click.

FEASIBILITY STUDY


9/37

The purpose of the Feasibility phase is to figure out

whether the proposed system development is giving long

term benefits more than the development cost or not. If the

idea of development is not feasibly possible then we have to

either change the idea or drop it.

1. Economic Feasibility:

The proposed project is having requirement of a computer system.

The client who is having the required equipment and facilities will

be able to run the S/W properly. So there is no additional cost for

implementing the project in the department under consideration.

Hence the project is economically feasible for the department.

2. Technical Feasibility:

Technical feasibility refers to the ability to develop the project

using technology in trade. The project under consideration is

technically possible using C programming language.

3. Operational Feasibility:

The potential candidates of the System under consideration are

the Faculty members & trainees. Though the games on this software

can be played by age 6+, all the candidates are well above thisrequirement. Both the trainees and Faculty in charge here are computer

literate so the project is operationally very much feasible.

WHAT IS COMPUTER GRAPHICS?

Computer graphics aregraphics created usingcomputers and, more

generally, the representation and manipulation ofimage data by a

computer with help from specialized software andhardware.

The development of computer graphics has made computers easier to

interact with, and better for understanding and interpreting many types

of data. Developments in computer graphics have had a profound

impact on many types of media and have revolutionizedanimation, movies and the video game industry.

OBJECTIVE OF THE PROGRAM.

The objective of spce jam is to destroy the enemy spaceships who

wants to destroy the universe by obeying the rules given below:-

1. The game starts giving basics about the game such as ...the

world is coming to an end... ...the devil is going to destroy the

universe... .

2. We have unlimited bullets to fire, the aim is to destroy the devil

with bullets. .

3. After the warning game can be continued by pressing any key.

4. The functions in the game can be performed by pressing keys

such as 8 and 2 to move the gun vertically.

5. Bullets can be shot at the enemy by left clicking.

6. As the game starts we can see our spaceship at the lower bottom

of the screen and the enemy spaceships coming towards our

spaceships and firing bullets.

7. The main objective of the game is to take the target from the

point using the valid moves.


12/37

8. If you succeeded in shooting and destroying all of the enemy

spaceships,, a message will appear on screen saying

...YOU'VE...WON... .

9. If you failed to destroy all the enemy spaceships and also failed

to protect the spaceship from the enemy then game will be over

and the following message will appear DESTROYED GAME

OVER.

10.At the end an EXIT message will appear asking for your choice if

you want to exit the game or not. If you want to exit press Y if

you dont press N.

including dynamic memory management, random

number

generation, communication with the environment,

integer

arithmetic, searching, sorting and converting.

C FUNCTIONS:

setcolor function in c :

Declaration :- void setcolor(int color);

In Turbo Graphics each color is assigned a number. Total 16 colors are

available. Strictly speaking number of available colors depends on

current graphics mode and driver.For Example :- BLACK is assigned 0,

RED is assigned 4 etc. setcolor function is used to change the currentdrawing color.e.g. setcolor(RED) or setcolor(4) changes the current

drawing color to RED. Remember that default drawing color is WHITE.


16/37

setfillstyle function in c :

setfillstyle function sets the current fill pattern and fill color.

Declaration :- void setfillstyle( int pattern, int color);

setfillstyle(SOLID_FILL,RED);

Pattern tells that which type of pattern has to be filled and color

specifies the color with which the pattern must be filled.

circle function in c :

Declaration :- void circle(int x, int y, int radius);

e.g. circle(50,50,15);

circle function is used to draw a circle with center (x,y) and third

parameter specifies the radius of the circle. The code given below

draws a circle.

floodfill function :

Declaration :- void floodfill(int x, int y, int border);


17/37

e.g. floodfill(50,50,WHITE);

floodfill function is used to fill an enclosed area. Current fill pattern

and fill color is used to fill the area.(x, y) is any point on the screen if

(x,y) lies inside the area then inside will be filled otherwise outside will

be filled,border specifies the color of boundary of area. To change fill

pattern and fill color use setfillstyle. Code given below draws a circle

and then fills it.

rectangle function in c :

Declaration :- void rectangle(int left, int top, int right, int bottom);

e.g. rectangle(0,0,maxx,maxy);

rectangle function is used to draw a rectangle. Coordinates of left top

and right bottom corner are required to draw the rectangle. Left

specifies the X-coordinate of top left corner, top specifies the Y-

coordinate of top left corner, right specifies the X-coordinate of right

bottom corner, bottom specifies the Y-coordinate of right bottom

corner. The code given below draws a rectangle.

arc function in c :

Declaration :- void arc(int x, int y, int stangle, int endangle, int radius);

e.g. arc(25,25,335,360,40);

arc function is used to draw an arc with center (x,y) and stangle

specifies starting angle, endangle specifies the end angle and last


18/37

parameter specifies the radius of the arc. arc function can also be used

to draw a circle but for that starting angle and end angle should be 0

and 360 respectively.

setviewport function in c :

setviewport function sets the current viewport for graphics output.

e.g. setviewport(1,1,maxx-1,maxy-1,1);

Declaration :- void setviewport(int left, int top, int right, int bottom, int

clip);

setviewport function is used to restrict drawing to a particular portion

on the screen. For example setviewport(100 , 100, 200, 200, 1);

will restrict our drawing activity inside the rectangle(100,100, 200,

200).

left, top, right, bottom are the coordinates of main diagonal of rectangle

in which we wish to restrict our drawing. Also note that the point (left,

top) becomes the new origin.

settextstyle function in c :

Settextstyle function is used to change the way in which text appears,

using it we can modify the size of text, change direction of text and

change the font of text.


19/37

e.g. settextstyle(1,0,3);

Declaration :- void settextstyle( int font, int direction, int charsize);

font argument specifies the font of text, Direction can be HORIZ_DIR

(Left to right) or VERT_DIR (Bottom to top).

outtextxy function in c :

outtextxy function display text or string at a specified point(x,y) on the

screen.

Declaration :- void outtextxy(int x, int y, char *string);

e.g. outtextxy(maxx/2,30,"...the world is coming to an end...");

x, y are coordinates of the point and third argument contains the

address of string to be displayed.

fillellipse function in c :

fillellipse is used to fill the ellipse drawn on the screen.

Declaration of fillellipse function :-

void fillellipse(int x, int y, int xradius, int yradius);x and y are coordinates of center of the ellipse, xradius and yradius are

x and y radius of ellipse respectively.


20/37

getimage function in c :

getimage function saves a bit image of specified region into memory,

region can be any rectangle.

Declaration:- void getimage(int left, int top, int right, int bottom, void

*bitmap);

e.g. getimage(25,25,75,75,buff);

getimage copies an image from screen to memory. Left, top, right, and

bottom define the area of the screen from which the rectangle is to be

copied, bitmap points to the area in memory where the bit image is

stored.

putimage function in c :

putimage function outputs a bit image onto the screen.

Declaration:- void putimage(int left, int top, void *ptr, int op);

e.g. putimage(25,25,buff,XOR_PUT);

putimage puts the bit image previously saved with getimage back onto

the screen, with the upper left corner of the image placed at (left, top).

ptr points to the area in memory where the source image is stored. The

op argument specifies a operator that controls how the color for each

destination pixel on screen is computed, based on pixel already on

screen and the corresponding source pixel in memory.


21/37

putpixel function in c :

putpixel function plots a pixel at location (x, y) of specified color.

Declaration :- void putpixel(int x, int y, int color);

e.g. putpixel(random(maxx),random(maxy),random(16));

For example if we want to draw a GREEN color pixel at (35, 45) then

we will write putpixel(35, 35, GREEN); in our c program, putpixel

function can be used to draw circles, lines and ellipses using various

algorithms.

setfillstyle function in c :

setfillstyle function sets the current fill pattern and fill color.

Declaration :- void setfillstyle( int pattern, int color);

e.g setfillstyle(SOLID_FILL,15);

closegraph function in c:

closegraph function closes the graphics mode, deallocates all memory

allocated by graphics system and restores the screen to the mode it was

in before you called initgraph.


22/37

Declaration :- void closegraph();

getmaxx function in c:

getmaxx function returns the maximum X coordinate for current

graphics mode and driver.

Declaration :- int getmaxx();

getmaxy function in c:

getmaxy function returns the maximum Y coordinate for current

graphics mode and driver.

Declaration :- int getmaxy();

delay function in c :


23/37

Delay in c: delay function is used to suspend execution of a program for

a particular time.

Declaration :- void delay(unsigned int);

e.g. delay(4000);

Here unsigned int is the number of milliseconds ( remember 1 second =

1000 milliseconds ). To use delay function in your program you should

include the dos.h header file.

sound function in c:

Declaration :

Void sound(int value);

e.g. sound(500);

Sound function is used to produce the audio effects with a parameter

int value.

SCREENSHOTS OF THE PROECT


24/37

There are some screenshots of the project, showing the outline of the

project

and the various actions which we can apply on it.

SCREENSHOT 1:

This shows the introductory face of the game which tells about the

worlds coming to an end and informing you to destroy the devil before

it destroys you.


25/37

SCREENSHOT 2:

The main front view of the project showing the objective and actions

that can be performed by the user in the game to SHOOT THE

DEVIL.


26/37

SCREENSHOT 3:

This is the actual starting face of the game, the white bold dot at the

extreme left is the GUN that shoots the bullets at the DEVIL

shown in red on the screen. At the top we can see the number of bullets

were left with which are at its initial in this shot i.e. 10.


27/37

SCREENSHOT 4:

This is the snapshot when there are still 8 bullets left with the players

and it shoots the devil. As soon as the bullet hits the devil, the

screenshot 4 appears to the player.


28/37

SCREENSHOT 5:

This shot appears when the devil is destroyed and the world is saved. It

displays the message YOUVE WON.


29/37

SCREENSHOT 6:

These are some other screenshots from the game where devil is moving

within the screen. Number of bullets left are 7. with each passing shot

the number of shots displayed on the screen will be reduced , updating

you about the number of shots left .


30/37

SCREENSHOT 7:

Now the devil has moved to upper part of the screen and number ofshots left with the player has reduced to 6.


31/37

SCREENSHOT 8:

The player has lost one more shot without hitting the target and now the

number of shots left is 4.


32/37

SCREENSHOT 9:


33/37

Now the player is left with just 2 last shots with which he has to shoot

the target else hell lost the game.

SCREENSHOT 10:


34/37

This is the last shot left with the player to destroy the devil , if the player

failed to hit it this time too, hell lose the game and the game will be

over.

SCREENSHOT 11:


35/37

This shot shows that the bullets are over with the player and that he

failed to shoot the target. The message Your bullets are over

The devil destroys the world will be displayed on the screen. And that

marks the end of the game.


36/37

CONCLUSION

The project report entitled "SPACE JAM" has come to its final

stage. The system has been developed with much care that it is free of

errors and at the same time it is efficient and less time consuming. The

important thing is that the system is robust. We have tried our level best

to make the game as dynamic as possible. Also provision is provided for

future developments in the system. The entire system is secured.
