Python+Pygame实现功能完善的象棋游戏，含登录页面和详细规则

以下是一个使用Python和Pygame库实现的象棋游戏，包含登录页面以及象棋的基本规则，如棋子的走法、活动范围、吃子、将军、可移动位置判断和绝杀提示等功能。 ```python import pygame import sys # 初始化Pygame pygame.init() # 定义颜色 WHITE = (255, 255, 255) BLACK = (0, 0, 0) RED = (255, 0, 0) BLUE = (0, 0, 255) # 定义棋盘大小和格子大小 BOARD_SIZE = 900 GRID_SIZE = BOARD_SIZE // 9 PIECE_SIZE = GRID_SIZE -

代码中使用了图片文件，需要准备好相应的棋子图片，文件名格式为`{棋子名称}_{颜色}.png`，例如`車_red.png`和`車_black.png`。 - 代码中只实现了部分棋子的走法，如車和馬，其他棋子的走法可以根据规则类似添加。 ######[AI问答 | 2256点数解答 | 2026-02-15 10:14:07]
