贪吃蛇代码
本帖最后由 MC.Steve 于 2026-2-10 14:54 编辑今天的主题是：贪吃蛇！（加强版明天发布）（不定期会出python的游戏）
贪吃蛇的程序语言：C语言、C++
保证鱼油能够在C语言、C++中玩到贪吃蛇
C语言：
#include <stdio.h>

接下来会有AI竞技、双人（可以@你的好基友来玩）
有想法可提出，将会有新版本 以下为C语言和C++的贪吃蛇基础版代码，代码已修正蛇身存储问题，确保可以正确运行。两个版本都使用了简单的控制台图形，通过键盘WASD控制方向，X键退出游戏。
#include <stdio.h>
#include <conio.h>
#include <windows.h>
#include <stdlib.h>
#define WIDTH 20
#define HEIGHT 15
int x, y, fruitX, fruitY, score;

printf("\n");
for (int i = 0; i < HEIGHT; i++) {
for (int j = 0; j < WIDTH; j++) {

}
}
int main() {
Setup();
while (dir != STOP) {
Draw();
Input();
Logic();
Sleep(100);
}
return 0;
}
C++版本（使用cout等C++特性）：
#include <iostream>
#include <conio.h>
#include <windows.h>
#include <cstdlib>
using namespace std;
const int WIDTH = 20;
const int HEIGHT = 15;
int x, y, fruitX, fruitY, score;
int tailX, tailY;
int nTail;
enum eDirection { STOP, LEFT, RIGHT, UP, DOWN };
eDirection dir;
void Setup() {
dir = STOP;
x = WIDTH / 2;
y = HEIGHT / 2;
fruitX = rand() % WIDTH;
fruitY = rand() % HEIGHT;
score = 0;
nTail = 0;
}
void Draw() {
system("cls");
for (int i = 0; i < WIDTH + 2; i++) cout << "#";
cout << endl;
for (int i = 0; i < HEIGHT; i++) {
for (int j = 0; j < WIDTH; j++) {
if (j == 0) cout << "#";
if (i == y && j == x) cout << "O";
else if (i == fruitY && j == fruitX) cout << "F";
else {
bool print = false;
for (int k = 0; k < nTail; k++) {
if (tailX == j && tailY == i) {
cout << "o";
print = true;
}
}
if (!print) cout << " ";
}
if (j == WIDTH - 1) cout << "#";
}
cout << endl;
}
for (int i = 0; i < WIDTH + 2; i++) cout << "#";
cout << endl << "Score:" << score << endl;
}
void Input() {
if (_kbhit()) {
switch (_getch()) {
case 'a': dir = LEFT; break;
case 'd': dir = RIGHT; break;
case 'w': dir = UP; break;
case 's': dir = DOWN; break;
case 'x': dir = STOP; break;
}
}
}
void Logic() {
int prevX = tailX;
int prevY = tailY;
int prev2X, prev2Y;
tailX = x;
tailY = y;
for (int i = 1; i < nTail; i++) {
prev2X = tailX;
prev2Y = tailY;
tailX = prevX;
tailY = prevY;
prevX = prev2X;
prevY = prev2Y;
}
switch (dir) {
case LEFT: x--; break;
case RIGHT: x++; break;
case UP: y--; break;
case DOWN: y++; break;
}
if (x >= WIDTH) x = 0; else if (x < 0) x = WIDTH - 1;
if (y >= HEIGHT) y = 0; else if (y < 0) y = HEIGHT - 1;
for (int i = 0; i < nTail; i++)
if (tailX == x && tailY == y)
dir = STOP;
if (x == fruitX && y == fruitY) {
score += 10;
nTail++;
fruitX = rand() % WIDTH;
fruitY = rand() % HEIGHT;
}
}
int main() {
Setup();
while (dir != STOP) {
Draw();
Input();
Logic();
Sleep(100);
}
return 0;
}
说明：
- 游戏界面宽度 WIDTH 和高度 HEIGHT 可修改。
- 蛇头用 O 表示，食物用 F 表示，蛇身用 o 表示。
- 通过 Sleep(100) 控制游戏速度，数值越大速度越慢。
- 注意：代码使用了 Windows 特有的头文件（如 windows.h 和 conio.h），如果在其他系统编译，可能需要替换相关函数。
