c语言贪吃蛇代码简短

C语言贪吃蛇的代码可以通过合理的算法设计和简洁的代码实现。以下是一个简短的示例：

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <time.h>

int width = 20;  // 游戏界面宽度
int height = 20; // 游戏界面高度
int gameOver = 0;
int score = 0;

int snakeX[100], snakeY[100];  // 蛇身坐标
int snakeLength = 1;          // 蛇身长度
int fruitX, fruitY;           // 水果坐标

enum Direction { STOP = 0, UP, DOWN, LEFT, RIGHT };  // 蛇运动方向
enum Direction dir;

void Setup()
{
    srand(time(NULL));
    gameOver = 0;
    dir = STOP;
    snakeX[0] = width / 2;
    snakeY[0] = height / 2;
    fruitX = rand() % (width - 1);
    fruitY = rand() % (height - 1);
    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 == snakeY[0] && j == snakeX[0])
                printf("O");
            else if (i == fruitY && j == fruitX)
                printf("@");
            else
            {
                int tailPrinted = 0;
                for (int k = 1; k < snakeLength; k++)
                {
                    if (snakeX[k] == j && snakeY[k] == i)
                    {
                        printf("o");
                        tailPrinted = 1;
                        break;
                    }
                }
                if (!tailPrinted)
                    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 'w':
            dir = UP;
            break;
        case 's':
            dir = DOWN;
            break;
        case 'a':
            dir = LEFT;
            break;
        case 'd':
            dir = RIGHT;
            break;
        case 'x':
            gameOver = 1;
            break;
        }
    }
}

void Logic()
{
    int prevX = snakeX[0];
    int prevY = snakeY[0];
    int prev2X, prev2Y;
    snakeX[0] += (dir == RIGHT) ? 1 : (dir == LEFT) ? -1 : 0;
    snakeY[0] += (dir == DOWN) ? 1 : (dir == UP) ? -1 : 0;
  
    for (int i = 1; i < snakeLength; i++)
    {
        prev2X = snakeX[i];
        prev2Y = snakeY[i];
        snakeX[i] = prevX;
        snakeY[i] = prevY;
        prevX = prev2X;
        prevY = prev2Y;
    }

    if (snakeX[0] >= width || snakeX[0] < 0 || snakeY[0] >= height || snakeY[0] < 0)
        gameOver = 1;

    for (int i = 1; i < snakeLength; i++)
    {
        if (snakeX[0] == snakeX[i] && snakeY[0] == snakeY[i])
            gameOver = 1;
    }

    if (snakeX[0] == fruitX && snakeY[0] == fruitY)
    {
        score += 10;
        fruitX = rand() % (width - 1);
        fruitY = rand() % (height - 1);
        snakeLength++;
    }
}

int main()
{
    Setup();

    while (!gameOver)
    {
        Draw();
        Input();
        Logic();
        // 控制游戏速度
        _sleep(10);
    }

    return 0;
}

以上代码为一个采用字符界面的简易贪吃蛇游戏实现，具备基本的蛇的移动、水果的生成与吃掉、边界碰撞和自身碰撞判断、分数统计等功能。同时，程序采用了简短的代码段实现游戏的逻辑处理。
