用c语言生成贪吃蛇的代码

以下是一个简单的用C语言生成贪吃蛇的代码，仅供参考：

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <time.h>
#define Up 1
#define Down 2
#define Left 3
#define Right 4
#define Width 30
#define Height 20
int x, y, fruitX, fruitY, score, gameover, speed;
int tailX[100], tailY[100], ntail;
int direction;
void setup()
{
    gameover = 0;
    direction = Right;
    x = Width / 2;
    y = Height / 2;
    fruitX = rand() % Width;
    fruitY = rand() % Height;
    score = 0;
    speed = 100;
}
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 print = 0;
                for (int k = 0; k < ntail; k++)
                {
                    if (tailX[k] == j && tailY[k] == i)
                    {
                        printf("o");
                        print = 1;
                    }
                }
                if (!print)
                    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':
            direction = Left;
            break;
        case 'd':
            direction = Right;
            break;
        case 'w':
            direction = Up;
            break;
        case 's':
            direction = 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 (direction)
    {
    case Up:
        y--;
        break;
    case Down:
        y++;
        break;
    case Left:
        x--;
        break;
    case Right:
        x++;
        break;
    default:
        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;
    }
    if (x == fruitX && y == fruitY)
    {
        score += 10;
        fruitX = rand() % Width;
        fruitY = rand() % Height;
        ntail++;
        if (score % 100 == 0)
            speed -= 10;
    }
}
int main()
{
    srand(time(NULL));
    setup();
    while (!gameover)
    {
        draw();
        input();
        logic();
        Sleep(speed);
    }
    printf("GAME OVER\n");
    printf("Score: %d\n", score);
    return 0;
}

该代码使用了Windows系统的conio.h库，可以通过键盘操作控制贪吃蛇的移动方向。其中，setup()函数初始化游戏界面和初始参数，draw()函数绘制游戏界面，input()函数获取玩家输入，logic()函数处理游戏逻辑。最后，在while循环中循环执行以上函数，直到游戏结束。
