C Program for Moving Car Animation Using C Graphics

Write a program in C for moving car animation using graphics.h header file

In this program, we will first draw a car and color it. In every iteration of for loop we keep on increasing the x coordinates of every point of car to make it look like this car is moving from left to right. We will use below mentioned graphics functions in this program.

Function Description
initgraph It initializes the graphics system by loading the passed graphics driver then changing the system into graphics mode.
getmaxx It returns the maximum X coordinate in current graphics mode and driver.
getmaxy It returns the maximum X coordinate in current graphics mode and driver.
setcolor It changes the current drawing colour. Default colour is white. Each color is assigned a number, like BLACK is 0 and RED is 4. Here we are using colour constants defined inside graphics.h header file.
setfillstyle It sets the current fill pattern and fill color.
circle It draws a circle with radius r and centre at (x, y).
line It draws a straight line between two points on screen.
arc It draws a circular arc from start angle till end angle.
floodfill It is used to fill a closed area with current fill pattern and fill color. It takes any point inside closed area and color of the boundary as input.
cleardevice It clears the screen, and sets current position to (0, 0).
delay It is used to suspend execution of a program for a M milliseconds.
closegraph It unloads the graphics drivers and sets the screen back to text mode.

C program for moving car graphics animation

In this program, we first draw a red color car on left side of the screen (x,y) and then erases it using cleardevice function. We again draw this car at(x + 5, y). This will look like a moving car from left to right direction. We will repeat above steps until car reaches the right side of screen.

#include <stdio.h>
#include <graphics.h>
#include <conio.h>
#include <dos.h>

int main() {
    int gd = DETECT, gm;
    int i, maxx, midy;

    /* initialize graphic mode */
    initgraph(&gd, &gm, "X:\\TC\\BGI");
    /* maximum pixel in horizontal axis */
    maxx = getmaxx();
    /* mid pixel in vertical axis */
    midy = getmaxy()/2;

    for (i=0; i < maxx-150; i=i+5) {
        /* clears screen */
        cleardevice();

        /* draw a white road */
        setcolor(WHITE);
        line(0, midy + 37, maxx, midy + 37);

        /* Draw Car */
        setcolor(YELLOW);
        setfillstyle(SOLID_FILL, RED);

        line(i, midy + 23, i, midy);
        line(i, midy, 40 + i, midy - 20);
        line(40 + i, midy - 20, 80 + i, midy - 20);
        line(80 + i, midy - 20, 100 + i, midy);
        line(100 + i, midy, 120 + i, midy);
        line(120 + i, midy, 120 + i, midy + 23);
        line(0 + i, midy + 23, 18 + i, midy + 23);
        arc(30 + i, midy + 23, 0, 180, 12);
        line(42 + i, midy + 23, 78 + i, midy + 23);
        arc(90 + i, midy + 23, 0, 180, 12);
        line(102 + i, midy + 23, 120 + i, midy + 23);
        line(28 + i, midy, 43 + i, midy - 15);
        line(43 + i, midy - 15, 57 + i, midy - 15);
        line(57 + i, midy - 15, 57 + i, midy);
        line(57 + i, midy, 28 + i, midy);
        line(62 + i, midy - 15, 77 + i, midy - 15);
        line(77 + i, midy - 15, 92 + i, midy);
        line(92 + i, midy, 62 + i, midy);
        line(62 + i, midy, 62 + i, midy - 15);
        floodfill(5 + i, midy + 22, YELLOW);
        setcolor(BLUE);
        setfillstyle(SOLID_FILL, DARKGRAY);
        /*  Draw Wheels */
        circle(30 + i, midy + 25, 9);
        circle(90 + i, midy + 25, 9);
        floodfill(30 + i, midy + 25, BLUE);
        floodfill(90 + i, midy + 25, BLUE);
        /* Add delay of 0.1 milli seconds */
        delay(100);
    }

    getch();
    closegraph();
    return 0;
}
