使用pygame写一个桃花棋游戏

好的，下面是使用Pygame实现桃花棋游戏的示例代码：

import pygame

# 初始化Pygame
pygame.init()

# 游戏窗口大小
WINDOW_SIZE = (400, 400)

# 颜色定义
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)

# 创建游戏窗口
screen = pygame.display.set_mode(WINDOW_SIZE)

# 设置窗口标题
pygame.display.set_caption("桃花棋")

# 定义棋盘格子大小和间隔
CELL_SIZE = 40
CELL_SPACING = 10

# 定义棋子半径
PIECE_RADIUS = 18

# 定义棋子颜色
PIECE_COLOR = (255, 0, 0)

# 定义棋盘坐标
board = [['O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'],
         ['O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'],
         ['O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'],
         ['O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'],
         ['O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'],
         ['O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'],
         ['O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'],
         ['O', 'O', 'O', 'O', 'O', 'O', 'O', 'O']]

# 定义当前落子方
current_player = 'B'

# 定义棋子位置
piece_x = 0
piece_y = 0


# 绘制棋盘
def draw_board():
    for x in range(8):
        for y in range(8):
            # 计算格子左上角坐标
            rect_x = CELL_SPACING + x * (CELL_SIZE + CELL_SPACING)
            rect_y = CELL_SPACING + y * (CELL_SIZE + CELL_SPACING)
            # 绘制格子
            pygame.draw.rect(screen, WHITE, (rect_x, rect_y, CELL_SIZE, CELL_SIZE))
            # 绘制棋子
            if board[x][y] == 'B':
                pygame.draw.circle(screen, PIECE_COLOR, (rect_x + CELL_SIZE // 2, rect_y + CELL_SIZE // 2), PIECE_RADIUS)
            elif board[x][y] == 'W':
                pygame.draw.circle(screen, WHITE, (rect_x + CELL_SIZE // 2, rect_y + CELL_SIZE // 2), PIECE_RADIUS, 2)


# 落子
def place_piece(x, y):
    global current_player
    if board[x][y] == 'O':
        board[x][y] = current_player
        if current_player == 'B':
            current_player = 'W'
        else:
            current_player = 'B'


# 主循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            # 获取鼠标点击坐标
            mouse_x, mouse_y = pygame.mouse.get_pos()
            # 计算棋子所在格子
            piece_x = (mouse_x - CELL_SPACING) // (CELL_SIZE + CELL_SPACING)
            piece_y = (mouse_y - CELL_SPACING) // (CELL_SIZE + CELL_SPACING)
            # 落子
            place_piece(piece_x, piece_y)

    # 绘制背景
    screen.fill(GREEN)

    # 绘制棋盘
    draw_board()

    # 绘制当前落子位置的提示圆圈
    pygame.draw.circle(screen, RED, (CELL_SPACING + piece_x * (CELL_SIZE + CELL_SPACING) + CELL_SIZE // 2, CELL_SPACING + piece_y * (CELL_SIZE + CELL_SPACING) + CELL_SIZE // 2), PIECE_RADIUS + 2, 2)

    # 刷新屏幕
    pygame.display.update()

# 退出Pygame
pygame.quit()

该示例代码实现了一个简单的桃花棋游戏，玩家可以通过点击鼠标来落子，程序会自动判断当前落子方并更新棋盘。游戏界面使用Pygame库绘制，实现了棋盘格子和棋子的绘制，以及落子位置的提示圆圈。
