开发一个俄罗斯方块

俄罗斯方块是一款经典的游戏，下面是一个简单的C++示例代码，用于实现俄罗斯方块：

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <conio.h>
#include <Windows.h>
using namespace std;

const int width = 10;
const int height = 20;

int board[height][width] = {0};

int shapes[7][4][2] = {
    {{0, 1}, {1, 1}, {2, 1}, {3, 1}},   // I
    {{0, 0}, {1, 0}, {1, 1}, {2, 1}},   // Z
    {{0, 1}, {1, 1}, {1, 0}, {2, 0}},   // S
    {{0, 0}, {0, 1}, {1, 0}, {1, 1}},   // O
    {{0, 1}, {1, 1}, {2, 1}, {2, 0}},   // L
    {{0, 1}, {1, 1}, {2, 1}, {0, 0}},   // J
    {{0, 1}, {1, 1}, {1, 0}, {2, 1}}    // T
};

void draw_board() {
    system("cls");
    for(int i = 0; i < height; i++) {
        for(int j = 0; j < width; j++) {
            if(board[i][j] == 0) {
                cout << ".";
            } else {
                cout << "#";
            }
        }
        cout << endl;
    }
}

void draw_shape(int x, int y, int shape) {
    for(int i = 0; i < 4; i++) {
        int px = x + shapes[shape][i][0];
        int py = y + shapes[shape][i][1];
        board[py][px] = 1;
    }
}

void erase_shape(int x, int y, int shape) {
    for(int i = 0; i < 4; i++) {
        int px = x + shapes[shape][i][0];

        int px = x + shapes[shape][i][0];
        int py = y + shapes[shape][i][1];
        if(px < 0 || px >= width || py < 0 || py >= height || board[py][px] == 1) {
            return true;
        }
    }
    return false;
}

int main() {
    srand(time(NULL));
    int shape = rand() % 7;
    int x = width / 2;
    int y = 0;
    int score = 0;
    bool game_over = false;

            }
        }
        
        if(check_collision(x, y + 1, shape)) {
            draw_shape(x, y, shape);
            int count = 0;
            for(int i = 0; i < height; i++) {

                    }
                }
                if(full) {
                    count++;
                    for(int k = i; k > 0; k--) {
                        for(int j = 0; j < width; j++) {
                            board[k][j] = board[k - 1][j];
                        }
                    }

        }
        
        Sleep(100);
    }
    
    draw_board();
    cout << "Game Over! Your score is " << score << endl;

}

该代码使用键盘输入来控制方块的移动和旋转，并使用计时器来控制方块的下落速度。游戏结束时，将显示得分并退出游戏。您可以根据需要添加其他功能，例如显示下一个方块、添加音效等。
