Balloon Shooting - A Game ( Mini Project )
--------------------------------------------------------------------------------
Description : This is a simple balloon shooting game made in C
language. In this game, there are number of balloons, a bow and
arrows for shooting the balloons. The balloons rise from the
lower portion of the screen. The bow is put on left side which
can move up and down. If you shoot a balloon you will get 20
points. There are total three levels in our game. There are 10
balloons and 6 arrows in first level. If you get a minimum score
of 100, you will be eligible for entering in second level. If
you not get this minimum score, you are not qualified for second
level and game will be over and you are looser. There are 8
balloons and 6 arrows in second level. If you get a minimum
score of 180, you will be eligible for entering in third level.
In third level there are 6 balloons and 6 arrows. If you
completed all the three levels, you will be winner. The up and
down arrow key are used for positioning the bow. The space key
will be used for shooting. Different Functions used in the
project:- void draw_balloon(int ,int ): This function is used
for drawing a balloon. In this function we first use setcolor
and setfillstyle which set the color red and also filling style.
After this we are using fillellipse for drawing the ballon and
line for drawing the thread. void draw_burst ( int x, int y ):
This function is used for making the image of bursting of
balloon. void draw_bow(int x, int y): This function is used for
drawing the bow. In this, we are using setcolor, setlinestyle
for setting the color and style of the line. After that we are
using line and arc functions for drawing the bow. void
draw_arrow(int x, int y): This function is used for drawing the
arrow. In which we are using linerel for drawing the arrow by
considering the relative position of each line. void shoot(int
*x, int *y): In this function we put the image of the arrow on
the screen when it desired. After shooting an arrow we decrease
the number of arrows. Here we also display the number of
remaining arrows. Pointers are used to pass the coordinates by
reference. void fly(int *x, int *y): This function is used for
flying the balloons. The balloons will fly from lower portion of
the screen to upper portion. If one balloon crosses the screen
or is shot then there is a decrement in number of balloons. We
also display the number of remaining balloons in this function.
void start(): This function is used for showing our welcome
screen. Here we are using setbkcolor, settextstyle, setcolor,
setusercharsize, outtextxy and in last clearviewport for
clearing the welcome screen. int testkeys(): This function is
used for getting the ascii code and scan code for the key
pressed.
