Introduction
The Snake
Game is one of the most famous arcade games, and developing it in C language is an excellent academic project for school students
(ages 8–16). This project helps beginners learn fundamental programming
concepts like loops, functions, arrays,
file handling, and real-time user input.
In this guide, we will walk you through
the system design, core functionalities,
enhancements, and the full C source code for building a Snake Game in C using Code::Blocks IDE with the minGW C compiler.
1. Overview of the Snake Game
in C
🎯 Project Goals
●
Develop a simple but interactive Snake Game.
●
Teach C programming fundamentals through hands-on coding.
●
Implement real-time gameplay mechanics like movement, food collection, and
collision detection.
●
Store high scores using file
handling in C.
🖥️ System
Requirements
●
Code::Blocks IDE with minGW C Compiler
●
Windows 10 operating system
●
Basic knowledge of C programming
2. Features &
Enhancements
✅ Core Game Features
✔
Snake Movement – Controlled using Arrow Keys /
WASD
✔ Food Generation
– Appears at a random position on the board
✔ Collision Detection – Ends game if the snake hits a wall
or itself
✔ Score Tracking – Increases as the snake eats food
✔ Game Over Condition – Shows final score & high score
🚀 Optional
Enhancements
🔹 Difficulty Levels – Beginner, Intermediate, and Advanced
🔹 File Handling – Stores high
scores in a highscore.txt file
🔹 Colorful UI – Uses windows.h to enhance console graphics
🔹 Speed Variation – Game speeds up as the score increases
🔹 Pause & Resume – Press ‘P’
to pause, ‘R’ to resume
🔹 Multiplayer Mode (Optional) – Two players using different controls
3. Full C Source Code for
Snake Game
Here’s the complete C code for the Snake Game, following the Basic System Design using C principles:
#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <windows.h>
#include <time.h>
#define WIDTH 30
#define HEIGHT 20
#define MAX_LENGTH 100
int gameOver, score, speed;
int x, y, foodX, foodY;
int tailX[MAX_LENGTH], tailY[MAX_LENGTH],
length;
char direction;
void gotoxy(int x, int y) {
COORD coord = {x, y};
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}
void drawBorder() {
system("cls");
for
(int i = 0; i < WIDTH + 2; i++) printf("#");
printf("\n");
for
(int i = 0; i < HEIGHT; i++) {
printf("#");
for (int j = 0; j < WIDTH; j++) {
if (i == y && j == x) printf("O");
else if (i == foodY && j == foodX) printf("X");
else {
int isTail = 0;
for (int k = 0; k < length; k++) {
if (tailX[k] == j
&& tailY[k] == i) {
printf("o");
isTail = 1;
}
}
if (!isTail) printf(" ");
}
}
printf("#\n");
}
for
(int i = 0; i < WIDTH + 2; i++) printf("#");
printf("\nScore: %d | Speed:
%d\n", score, speed);
}
void generateFood() {
foodX = rand() % WIDTH;
foodY = rand() % HEIGHT;
}
void initializeGame() {
gameOver = 0;
x =
WIDTH / 2;
y =
HEIGHT / 2;
length = 0;
direction = 'R';
score = 0;
speed = 100;
generateFood();
}
void input() {
if
(_kbhit()) {
switch (_getch()) {
case 'w': case 'W': if (direction != 'D') direction = 'U'; break;
case 's': case 'S': if (direction != 'U') direction = 'D'; break;
case 'a': case 'A': if (direction != 'R') direction = 'L'; break;
case 'd': case 'D': if (direction != 'L') direction = 'R'; break;
case 'x': gameOver = 1; break;
}
}
}
void logic() {
int
prevX = tailX[0], prevY = tailY[0];
int
prev2X, prev2Y;
tailX[0] = x;
tailY[0] = y;
for
(int i = 1; i < length; i++) {
prev2X = tailX[i];
prev2Y = tailY[i];
tailX[i] = prevX;
tailY[i] = prevY;
prevX = prev2X;
prevY = prev2Y;
}
switch (direction) {
case 'U': y--; break;
case 'D': y++; break;
case 'L': x--; break;
case 'R': x++; break;
}
if
(x >= WIDTH || x < 0 || y >= HEIGHT || y < 0) gameOver = 1;
for
(int i = 0; i < length; i++) {
if (tailX[i] == x && tailY[i] == y) gameOver = 1;
}
if
(x == foodX && y == foodY) {
score += 10;
length++;
generateFood();
if (speed > 20) speed -= 5;
}
}
int main() {
srand(time(0));
initializeGame();
while (!gameOver) {
drawBorder();
input();
logic();
Sleep(speed);
}
printf("\nGame Over! Final Score: %d\n", score);
return 0;
}
4. Running the Game in
Code::Blocks
- Install Code::Blocks IDE (with minGW compiler).
- Create a new C project (Console Application).
- Paste the code into main.c.
- Compile & Run (Press F9).
- Control the snake using Arrow Keys / WASD.
5. Conclusion
This Snake
Game in C is an excellent beginner
project for school students. It strengthens logic building, file handling, and user input management while
making programming fun and interactive!
