用windows计时器实现c语言控制台版的贪吃蛇代码实现

好的，以下是用 Windows 计时器实现 C 语言控制台版贪吃蛇的代码实现：

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

#define width 60
#define height 20

enum Direction {UP, DOWN, LEFT, RIGHT};

int snake[width * height][2];
int food[2];
int length = 0;
int score = 0;
int direction = RIGHT;
int speed = 100;

void gotoxy(int x, int y) 
{
    COORD pos = { x, y };
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);
}

void hidecursor() 
{
    CONSOLE_CURSOR_INFO cursor_info = { 1, 0 };
    SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE), &cursor_info);
}

void initSnake() 
{
    int x = width / 2, y = height / 2;
    for (int i = 0; i < 5; i++) 
    {
        snake[i][0] = x - i;
        snake[i][1] = y;
    }
    length = 5;
}

void initFood() 
{
    srand(time(NULL));
    int x = rand() % (width - 1) + 1;
    int y = rand() % (height - 1) + 1;
    food[0] = x;
    food[1] = y;
}

void drawSnake() 
{
    for (int i = 0; i < length; i++) 
    {
        gotoxy(snake[i][0], snake[i][1]);
        printf("*");
    }
}

void drawFood() 
{
    gotoxy(food[0], food[1]);
    printf("#");
}

void move() 
{
    switch (direction) 
    {
    case UP:
        snake[length][0] = snake[length - 1][0];
        snake[length][1] = snake[length - 1][1] - 1;
        break;
    case DOWN:
        snake[length][0] = snake[length - 1][0];
        snake[length][1] = snake[length - 1][1] + 1;
        break;
    case LEFT:
        snake[length][0] = snake[length - 1][0] - 1;
        snake[length][1] = snake[length - 1][1];
        break;
    case RIGHT:
        snake[length][0] = snake[length - 1][0] + 1;
        snake[length][1] = snake[length - 1][1];
        break;
    }
    if (snake[length][0] == food[0] && snake[length][1] == food[1]) 
    {
        initFood();
        length++;
        score++;
        if (score % 5 == 0) 
        {
            speed -= 10;
        }
    }
    for (int i = 0; i < length; i++) 
    {
        if (i == length - 1) 
        {
            break;
        }
        if (snake[length - 1][0] == snake[i][0] && snake[length - 1][1] == snake[i][1]) 
        {
            printf("\a");
            gotoxy(0, height + 1);
            printf("Game Over!\n");
            exit(0);
        }
    }
    for (int i = 0; i < length - 1; i++) 
    {
        snake[i][0] = snake[i + 1][0];
        snake[i][1] = snake[i + 1][1];
    }
}

void updateScore() 
{
    gotoxy(0, height + 1);
    printf("Score: %d", score);
}

void changeDirection() 
{
    if (_kbhit()) 
    {
        char ch = _getch();
        switch (ch) 
        {
        case 'w':
        case 'W':
            if (direction != DOWN) 
            {
                direction = UP;
            }
            break;
        case 's':
        case 'S':
            if (direction != UP) 
            {
                direction = DOWN;
            }
            break;
        case 'a':
        case 'A':
            if (direction != RIGHT) 
            {
                direction = LEFT;
            }
            break;
        case 'd':
        case 'D':
            if (direction != LEFT) 
            {
                direction = RIGHT;
            }
            break;
        }
    }
}

void gameLoop() 
{
    while (1) 
    {
        drawSnake();
        drawFood();
        updateScore();
        changeDirection();
        move();
        Sleep(speed);
        system("cls");
    }
}

int main() 
{
    hidecursor();
    initSnake();
    initFood();
    gameLoop();
    return 0;
}

代码中用到了 Windows API 中的一些函数，如 `getch()`、`Sleep()`、`SetConsoleCursorPosition()` 等，需要在 Windows 平台上运行。其中，`initSnake()` 函数初始化蛇的位置，`initFood()` 函数初始化食物的位置，`drawSnake()` 和 `drawFood()` 函数分别绘制蛇和食物，`move()` 函数控制蛇的移动，`updateScore()` 函数更新分数，`changeDirection()` 函数监听键盘输入并改变蛇的移动方向，`gameLoop()` 函数是游戏的主循环，其中不断重绘和更新蛇、食物、分数等。
