c语言 俄罗斯方块代码

以下是一个基于C语言的简单俄罗斯方块代码：

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

#define WIDTH 10
#define HEIGHT 20

int score = 0; // 记录得分
int map[HEIGHT][WIDTH] = { 0 }; // 地图
int x = 0, y = 0; // 方块左上角坐标
int block[4][4] = { 0 }; // 当前方块
int next[4][4] = { 0 }; // 下一个方块
int blockType = 0; // 当前方块类型
int nextType = 0; // 下一个方块类型

// 初始化方块
void initBlock() {
    int types[7][4][4] = {
        { // I

这段代码基于控制台，使用了Windows.h库的Sleep函数和conio.h库的_kbhit、_getch函数。运行后，使用方向键和wasd键控制方块移动，按下空格键可以将方块直接放到底部。
