用c++编写俄罗斯方块游戏

好的，下面是一个简单的俄罗斯方块游戏的 C++ 代码，你可以参考一下：

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

const int width = 12;       // 游戏区宽度
const int height = 20;      // 游戏区高度
const int blockWidth = 4;   // 方块宽度
const int blockHeight = 4;  // 方块高度
const int startX = width / 2 - blockWidth / 2;  // 方块初始位置
const int startY = 0;

char blockShapes[7][4][4] = {  // 七种方块的形状
    { "....", "....", ".00.", ".00." },
    { "....", "..0.", ".00.", ".0.." },
    { "....", ".0..", ".00.", "..0." },
    { "....", "..0.", "..0.", ".00." },
    { "....", "..0.", ".00.", ".0.." },
    { "....", ".0..", ".00.", ".0.." },
    { "....", ".00.", ".00.", "...." }
};

int gameArea[height][width] = {};  // 游戏区

void drawGameArea() {  // 绘制游戏区
    system("cls");  // 清屏
    for (int i = 0; i < height; i++) {
        for (int j = 0; j < width; j++) {
            if (gameArea[i][j] == 0) {
                cout << ".";
            } else {
                cout << "0";
            }
        }
        cout << endl;
    }
}

bool checkCollision(int blockX, int blockY, int blockType) {  // 检查方块是否与已有方块冲突
    for (int i = 0; i < blockHeight; i++) {
        for (int j = 0; j < blockWidth; j++) {
            if (blockShapes[blockType][i][j] == '0') {
                int x = blockX + j;
                int y = blockY + i;
                if (x < 0 || x >= width || y >= height) {
                    return true;
                }
                if (y >= 0 && gameArea[y][x] != 0) {
                    return true;
                }
            }
        }
    }
    return false;
}

void placeBlock(int blockX, int blockY, int blockType) {  // 放置方块
    for (int i = 0; i < blockHeight; i++) {
        for (int j = 0; j < blockWidth; j++) {
            if (blockShapes[blockType][i][j] == '0') {
                int x = blockX + j;
                int y = blockY + i;
                gameArea[y][x] = blockType + 1;
            }
        }
    }
}

void removeFullLines() {  // 移除已满行
    int fullLineCount = 0;
    for (int i = height - 1; i >= 0; i--) {
        bool fullLine = true;
        for (int j = 0; j < width; j++) {
            if (gameArea[i][j] == 0) {
                fullLine = false;
                break;
            }
        }
        if (fullLine) {
            fullLineCount++;

                for (int k = 0; k < width; k++) {
                    gameArea[j + 1][k] = gameArea[j][k];
                }
            }
            for (int j = 0; j < width; j++) {

            }
            i++;
        }
    }
    if (fullLineCount > 0) {
        Sleep(100);  // 等待一段时间，让玩家看清楚哪些行被移除了
    }
}

int main() {
    srand(time(NULL));  // 初始化随机数生成器

    int currentBlockX = startX;

    int score = 0;

    while (true) {
        drawGameArea();

        // 绘制下一个方块
        cout << "Next block:" << endl;
        for (int i = 0; i < blockHeight; i++) {

                } else {

                }
            }
            cout << endl;
        }

        // 移动方块
        if (_kbhit()) {  // 如果有按键输入
            char ch = _getch();
            if (ch == 'a' && !checkCollision(currentBlockX - 1, currentBlockY, currentBlockType)) {
                currentBlockX--;
            }
            if (ch == 'd' && !checkCollision(currentBlockX + 1, currentBlockY, currentBlockType)) {

                int newBlockType = (currentBlockType + 1) % 4;
                if (!checkCollision(currentBlockX, currentBlockY, newBlockType)) {
                    currentBlockType = newBlockType;
                }
            }
        } else {  // 如果没有按键输入，则让方块自动下落
            if (!checkCollision(currentBlockX, currentBlockY + 1, currentBlockType)) {
                currentBlockY++;
            } else {
                placeBlock(currentBlockX, currentBlockY, currentBlockType);
                removeFullLines();

                    cout << "Game over!" << endl;
                    cout << "Your score: " << score << endl;
                    system("pause");
                    return 0;
                }
            }
        }
    }

    return 0;
}

这个代码使用了 Windows API 中的 `Sleep()` 函数来控制游戏速度，如果你在 Linux 或 macOS 上编译运行这个代码，可能需要使用其他方式来控制游戏速度。
