用C语言实现俄罗斯方块小游戏简单代码

当然可以！以下是一个简单的用C语言实现俄罗斯方块小游戏的代码示例：

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

#define WIDTH 10
#define HEIGHT 20

    int i, j;
    for (i = 0; i < HEIGHT; i++) {
        for (j = 0; j < WIDTH; j++) {
            if (board[i][j] == 0)
                printf(" ");
            else
                printf("*");
        }
        printf("\n");
    }
}

void drawPiece() {
    int i, j;
    for (i = 0; i < 4; i++) {
        for (j = 0; j < 4; j++) {
            if (currentPiece[i][j] == 1) {
                board[currentY + i][currentX + j] = 1;
            }
        }
    }
}

int checkCollision() {
    int i, j;
    for (i = 0; i < 4; i++) {

            if (currentPiece[i][j] == 1 && (currentX + j >= WIDTH || currentX + j < 0 || currentY + i >= HEIGHT || board[currentY + i][currentX + j] == 1))
                return 1;
        }
    }
    return 0;
}

        }
    }
}

                    board[k][j] = board[k - 1][j];
                }
            }

            }
        }

        // 生成新的方块
        int nextPiece = rand() % 7;

这是一个基本的俄罗斯方块游戏代码，使用了Windows.h头文件中的conio.h库来获取用户输入，使用了Windows的命令行窗口来进行绘制。你可以使用gcc编译器来编译运行该代码。

注意：这只是一个简单的示例，可能还需要进行进一步的优化和改进，比如添加计分系统、游戏结束判断等。希望对你有所帮助！
