C语言俄罗斯方块代码

C语言俄罗斯方块代码是一种使用C语言编写的经典游戏代码，它实现了俄罗斯方块游戏的基本功能。以下是一个简单的C语言俄罗斯方块代码的示例：

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

#define WIDTH 10
#define HEIGHT 20

int board[HEIGHT][WIDTH] = {0};
int currentPiece[4][4] = {0};
int currentX = 0;
int currentY = 0;

void generatePiece() {
    // 生成随机方块
    int pieces[7][4][4] = {
        {{1, 1, 1, 1}, {0, 0, 0, 0}, {0, 0, 0, 0}, {0 0, 0, 0}},
        {{1, 1, 1, 0}, {1, 0, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}},
        {{1, 1, 1, 0}, {0, 0, 1, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}},
        {{1, 1, 1, 0}, {0, 1, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}},
        {{1, 1, 0, 0}, {1, 1, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}},
        {{1, 1, 0, 0}, {0, 1, 1, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}},
        {{0, 1, 1, 0}, {1, 1, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}}
    };
    int randomIndex = rand() % 7;
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            currentPiece[i][j] = pieces[randomIndex][i][j];
        }
    }
    currentX = WIDTH / 2 - 2;
    currentY = 0;
}

int checkCollision(int x, int y) {
    // 检查方块是否与边界或已有方块碰撞
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            if (currentPiece[i][j] != 0 && (x + j < 0 || x + j >= WIDTH || y + i >= HEIGHT || board[y + i][x + j] != 0)) {
                return 1;
            }
        }
    }
    return 0;
}

void mergePiece() {
    // 将当前方块合并到已有方块中
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            if (currentPiece[i][j] != 0) {
                board[currentY + i][currentX + j] = currentPiece[i][j];
            }
        }
    }
}

void clearLines() {
    // 消除满行
    for (int i = HEIGHT - 1; i >= 0; i--) {
        int isFull = 1;
        for (int j = 0; j < WIDTH; j++) {
            if (board[i][j] == 0) {
                isFull = 0;
                break;
            }
        }
        if (isFull) {
            for (int k = i; k > 0; k--) {
                for (int j = 0; j < WIDTH; j++) {
                    board[k][j] = board[k - 1][j];
                }
            }
            for (int j = 0; j < WIDTH; j++) {
                board[0][j] = 0;
            }
        }
    }
}

void drawBoard() {
    // 绘制游戏界面
    system("cls");
    for (int i = 0; i < HEIGHT; i++) {
        for (int j = 0; j < WIDTH; j++) {
            if (board[i][j] != 0) {
                printf("■ ");
            } else {
                printf("  ");
            }
        }
        printf("\n");
    }
}

int main() {
    srand(time(NULL));
    generatePiece();
    while (1) {
        drawBoard();
        if (checkCollision(currentX, currentY + 1)) {
            mergePiece();
            clearLines();
            generatePiece();
            if (checkCollision(currentX, currentY)) {
                break;
            }
        } else {
            currentY++;
        }
        if (_kbhit()) {
            char key = _getch();
            switch (key) {
                case 'a':
                    if (!checkCollision(currentX - 1, currentY)) {
                        currentX--;
                    }
                    break;
                case 'd':
                    if (!checkCollision(currentX + 1, currentY)) {
                        currentX++;
                    }
                    break;
                case 's':
                    while (!checkCollision(currentX, currentY + 1)) {
                        currentY++;
                    }
                    break;
                case 'q':
                    exit(0);
            }
        }
    }
    printf("Game Over!\n");
    return 0;
}

这段代码实现了一个简单的俄罗斯方块游戏，包括生成随机方块、检测碰撞、合并方块、消除满行等功能。你可以在此基础上进行修改和扩展，实现更多的游戏功能。
