Snake game using C++ complete code is demanded by many friend ! so i decided to write an article, providing you complete code Â of Snake game in c++ without any error ðŸ™‚

Change the headers according to your compiler.

here you go snake game ðŸ™‚

Things you need to do are :

Copy the code below
Paste into your desired environment (dev c++, visual studio)
compile and runÂ

#include <iostream>

#include <conio.h>

void run();
void printMap();
void initMap();
void move(int dx, int dy);
void update();
void changeDirection(char key);
void clearScreen();
void generateFood();

char getMapValue(int value);

// Map dimensions
const int mapwidth = 20;
const int mapheight = 20;

const int size = mapwidth * mapheight;

// The tile values for the map
int map[size];

// Snake head details
int headxpos;
int headypos;
int direction;

// Amount of food the snake has (How long the body is)
int food = 3;

// Determine if game is running
bool running;

int main()
{
run();
return 0;
}

// Main game function
void run()
{
// Initialize the map
initMap();
running = true;
while (running) {
// If a key is pressed
if (kbhit()) {
// Change to direction determined by key pressed
changeDirection(getch());
}
// Upate the map
update();

// Clear the screen
clearScreen();

// Print the map
printMap();

// wait 0.5 seconds
_sleep(500);
}

// Print out game over text
std::cout << “tt!!!Game over!” << std::endl << “ttYour score is: ” << food;

// Stop console from closing instantly
std::cin.ignore();
}

// Changes snake direction from input
void changeDirection(char key) {
/*
W
A + D
S

1
4 + 2
3
*/
switch (key) {
case ‘w’:
if (direction != 2) direction = 0;
break;
case ‘d’:
if (direction != 3) direction = 1;
break;
case ‘s’:
if (direction != 4) direction = 2;
break;
case ‘a’:
if (direction != 5) direction = 3;
break;
}
}

// Moves snake head to new location
void move(int dx, int dy) {
// determine new head position
int newx = headxpos + dx;
int newy = headypos + dy;

// Check if there is food at location
if (map[newx + newy * mapwidth] -2) {
// Increase food value (body length)
food++;

// Generate new food on map
generateFood();
}

// Check location is free
else if (map[newx + newy * mapwidth] != 0) {
running = false;
}

// Move head to new location
headxpos = newx;
headypos = newy;
map[headxpos + headypos * mapwidth] = food + 1;

}

// Clears screen
void clearScreen() {
// Clear the screen
system(“cls”);
}

// Generates new food on map
void generateFood() {
int x = 0;
int y = 0;
do {
// Generate random x and y values within the map
x = rand() % (mapwidth – 2) + 1;
y = rand() % (mapheight – 2) + 1;

// If location is not free try again
} while (map[x + y * mapwidth] != 0);

// Place new food
map[x + y * mapwidth] = -2;
}

// Updates the map
void update() {
// Move in direction indicated
switch (direction) {
case 0: move(-1, 0);
break;
case 1: move(0, 1);
break;
case 2: move(1, 0);
break;
case 3: move(0, -1);
break;
}

// Reduce snake values on map by 1
for (int i = 0; i < size; i++) {
if (map[i] > 0) map[i]–;
}
}

// Initializes map
void initMap()
{
// Places the initual head location in middle of map
headxpos = mapwidth / 2;
headypos = mapheight / 2;
map[headxpos + headypos * mapwidth] = 1;

// Places top and bottom walls
for (int x = 0; x < mapwidth; ++x) {
map[x] = -1;
map[x + (mapheight – 1) * mapwidth] = -1;
}

// Places left and right walls
for (int y = 0; y < mapheight; y++) {
map[0 + y * mapwidth] = -1;
map[(mapwidth – 1) + y * mapwidth] = -1;
}// Generates first food
generateFood();
}

// Prints the map to console
void printMap()
{
for (int x = 0; x < mapwidth; ++x) {
for (int y = 0; y < mapheight; ++y) {
// Prints the value at current x,y location
std::cout << getMapValue(map[x + y * mapwidth]);
}
// Ends the line for next x value
std::cout << std::endl;
}
}

// Returns graphical character for display from map value
char getMapValue(int value)
{
// Returns a part of snake body
if (value > 0) return ‘o’;

switch (value) {
// Return wall
case -1: return ‘X’;
// Return food
case -2: return ‘O’;
}
}
