俄罗斯方块源码,如何实现这一经典游戏的核心算法?

俄罗斯方块源码通常包含游戏逻辑、界面绘制和用户交互等部分。它通过编程语言实现,如C++、Java或Python等。在源码中,会定义方块的形状、颜色、移动、旋转以及消除等规则。还会处理用户输入,如键盘操作来控制方块的移动和旋转。源码还会包含计时器、得分系统等功能,以增加游戏的趣味性和挑战性。

由于俄罗斯方块的源码较长,这里给出一个简化版的C语言实现,这个版本仅包含基本的游戏逻辑和简单的图形界面,你可以在此基础上进行扩展和优化。

俄罗斯方块源码,如何实现这一经典游戏的核心算法?

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <windows.h>
#define WIDTH 10
#define HEIGHT 20
int board[HEIGHT][WIDTH] = {0};
int current_x, current_y;
int current_block[4][4];
void draw_board() {
    system("cls");
    for (int y = 0; y < HEIGHT; y++) {
        for (int x = 0; x < WIDTH; x++) {
            if (board[y][x]) {
                printf("■");
            } else {
                printf("□");
            }
        }
        printf("
");
    }
}
void draw_current_block() {
    for (int y = 0; y < 4; y++) {
        for (int x = 0; x < 4; x++) {
            if (current_block[y][x]) {
                board[current_y + y][current_x + x] = 1;
            }
        }
    }
}
void remove_current_block() {
    for (int y = 0; y < 4; y++) {
        for (int x = 0; x < 4; x++) {
            if (current_block[y][x]) {
                board[current_y + y][current_x + x] = 0;
            }
        }
    }
}
int can_move(int dx, int dy) {
    for (int y = 0; y < 4; y++) {
        for (int x = 0; x < 4; x++) {
            if (current_block[y][x]) {
                int new_x = current_x + x + dx;
                int new_y = current_y + y + dy;
                if (new_x < 0 || new_x >= WIDTH || new_y < 0 || new_y >= HEIGHT || board[new_y][new_x]) {
                    return 0;
                }
            }
        }
    }
    return 1;
}
void move_block(int dx, int dy) {
    if (can_move(dx, dy)) {
        remove_current_block();
        current_x += dx;
        current_y += dy;
        draw_current_block();
    }
}
void rotate_block() {
    // TODO: Implement block rotation logic
}
int main() {
    current_x = WIDTH / 2  2;
    current_y = 0;
    // TODO: Initialize the current_block with a random shape
    draw_current_block();
    while (1) {
        if (_kbhit()) {
            char key = _getch();
            switch (key) {
                case 'a': move_block(1, 0); break;
                case 'd': move_block(1, 0); break;
                case 's': move_block(0, 1); break;
                case 'w': rotate_block(); break;
            }
        }
        draw_board();
        Sleep(100); // Delay to control the speed of the game
    }
    return 0;
}

这个代码实现了一个简单的俄罗斯方块游戏,包括绘制游戏界面、移动方块、旋转方块等功能,它还没有实现方块自动下落、消除行以及游戏结束判断等功能,你可以在此基础上继续完善这个游戏。
