c语言俄罗斯方块简单源代码

以下是一个简单的 C 语言俄罗斯方块源代码：

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

#define WIDTH 10
#define HEIGHT 20

int board[HEIGHT][WIDTH];

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

typedef struct {

    }
    placePiece();

这个源代码实现了一个简单的俄罗斯方块游戏，可以使用 WASD 控制方块的移动和旋转。
