c语言俄罗斯方块简易

C语言俄罗斯方块是一个经典的游戏，可以通过使用C语言编写一个简易版本。下面是一个简单的示例代码，演示了如何使用C语言实现俄罗斯方块游戏：

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

#define WIDTH 10
#define HEIGHT 20

int field[HEIGHT][WIDTH] = {0};

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

int rotate(int shape[], int rotation) {
    int newShape[4] = {0};
    int index = 0;
    for (int i = 0; i < 4; i++) {
        int x = i % 2;
        int y = i / 2;
        int newX = -y;
        int newY = x;
        int newIndex = newY * 2 + newX;
        newShape[newIndex] = shape[i];
    }
    return newShape[rotation % 4];
}

int checkCollision(int x, int y, int shape[], int rotation) {
    for (int i = 0; i < 4; i++) {
        int newX = x + i % 2;
        int newY = y + i / 2;
        int index = newY * WIDTH + newX;
        if (newX < 0 || newX >= WIDTH || newY >= HEIGHT || (newY >= 0 && field[newY][newX] != 0 && shape[rotate(shape, rotation) * 4 + i] != 0)) {
            return 1;
        }
    }
    return 0;
}

void drawField() {
    system("cls");
    for (int y = 0; y < HEIGHT; y++) {
        for (int x = 0; x < WIDTH; x++) {
            printf(field[y][x] ? "*" : " ");
        }
        printf("\n");
    }
}

void drawShape(int x, int y, int shape[], int rotation) {
    for (int i = 0; i < 4; i++) {
        int newX = x + i % 2;
        int newY = y + i / 2;
        if (newY >= 0 && shape[rotate(shape, rotation) * 4 + i] != 0) {
            field[newY][newX] = 1;
        }
    }
}

void clearShape(int x, int y, int shape[], int rotation) {
    for (int i = 0; i < 4; i++) {
        int newX = x + i % 2;
        int newY = y + i / 2;
        if (newY >= 0 && shape[rotate(shape, rotation) * 4 + i] != 0) {
            field[newY][newX] = 0;
        }
    }
}

int main() {
    int x = WIDTH / 2 - 2;
    int y = 0;
    int shapeIndex = rand() % 7;
    int rotation = 0;

    while (!gameOver) {
        drawField();
        drawShape(x, y, shapes[shapeIndex], rotation);

                        x--;
                    }

                        clearShape(x, y, shapes[shapeIndex], rotation);
                        rotation++;
                    }
                    break;
                case 'q':
                    gameOver = 1;
                    break;
            }
        }

        if (checkCollision(x, y + 1, shapes[shapeIndex], rotation)) {
            drawShape(x, y, shapes[shapeIndex], rotation);
            shapeIndex = rand() % 7;

            Sleep(500);
            clearShape(x, y, shapes[shapeIndex], rotation);

    printf("Game Over!\n");

}

这段代码使用了Windows.h头文件中的conio.h和windows.h库来实现在Windows命令行中显示游戏界面。你可以将代码复制到一个C文件中，并使用C编译器进行编译和运行。
