c语言贪吃蛇游戏

以下是一个基于 C 语言的简单贪吃蛇游戏的示例代码：

#include <stdio.h>
#include <conio.h>
#include <windows.h>

#define WIDTH 20
#define HEIGHT 20

int gameOver;
int x, y, fruitX, fruitY, score;
int tailX[100], tailY[100];
int nTail;
enum eDirection { STOP = 0, LEFT, RIGHT, UP, DOWN };
enum eDirection dir;

void Setup()
{
    gameOver = 0;
    dir = STOP;
    x = WIDTH / 2;
    y = HEIGHT / 2;
    fruitX = rand() % WIDTH;
    fruitY = rand() % HEIGHT;
    score = 0;
}

void Draw()
{
    system("cls");

    for (int i = 0; i < WIDTH + 2; i++)
        printf("#");
    printf("\n");

    for (int i = 0; i < HEIGHT; i++)
    {
        for (int j = 0; j < WIDTH; j++)
        {
            if (j == 0)
                printf("#");
                
            if (i == y && j == x)
                printf("O");
            else if (i == fruitY && j == fruitX)
                printf("F");
            else
            {
                int printTail = 0;
                for (int k = 0; k < nTail; k++)
                {
                    if (tailX[k] == j && tailY[k] == i)
                    {
                        printf("o");
                        printTail = 1;
                    }
                }
                if (!printTail)
                    printf(" ");
            }
            
            if (j == WIDTH - 1)
                printf("#");
        }
        printf("\n");
    }

    for (int i = 0; i < WIDTH + 2; i++)
        printf("#");
    printf("\n");

    printf("Score: %d\n", score);
}

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':
            gameOver = 1;
            break;
        }
    }
}

void Logic()
{
    int prevX = tailX[0];
    int prevY = tailY[0];
    int prev2X, prev2Y;
    tailX[0] = x;
    tailY[0] = y;
    for (int i = 1; i < nTail; i++)
    {
        prev2X = tailX[i];
        prev2Y = tailY[i];
        tailX[i] = prevX;
        tailY[i] = 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[i] == x && tailY[i] == y)
        {
            gameOver = 1;
            break;
        }
    }

    if (x == fruitX && y == fruitY)
    {
        score += 10;
        fruitX = rand() % WIDTH;
        fruitY = rand() % HEIGHT;
        nTail++;
    }
}

int main()
{
    Setup();
    while (!gameOver)
    {
        Draw();
        Input();
        Logic();
        Sleep(10); // 控制游戏速度
    }
    return 0;
}

这段代码实现了一个简单的控制台贪吃蛇游戏。你可以将代码复制到 C 语言的开发环境中，如 Dev-C++、Code::Blocks 等，然后编译和运行它。请注意，此代码可能需要在 Windows 环境下运行，因为使用了 conio.h 头文件的一些函数和 windows.h 头文件的 Sleep() 函数。
