用Python实现五子棋游戏

以下是一种可能的实现方式：

import pygame

# 设置游戏界面尺寸
SCREEN_WIDTH = 640
SCREEN_HEIGHT = 640

# 设置棋盘尺寸和格子大小
BOARD_SIZE = 15
GRID_SIZE = SCREEN_WIDTH // BOARD_SIZE

# 定义棋子颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

# 初始化 pygame
pygame.init()

# 创建游戏窗口
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("五子棋")

# 画棋盘
def draw_board():
    for i in range(BOARD_SIZE):
        pygame.draw.line(screen, BLACK, (GRID_SIZE // 2, GRID_SIZE // 2 + i * GRID_SIZE), 
                         (SCREEN_WIDTH - GRID_SIZE // 2, GRID_SIZE // 2 + i * GRID_SIZE))
        pygame.draw.line(screen, BLACK, (GRID_SIZE // 2 + i * GRID_SIZE, GRID_SIZE // 2), 
                         (GRID_SIZE // 2 + i * GRID_SIZE, SCREEN_HEIGHT - GRID_SIZE // 2))

# 下棋子
def place_piece(grid_x, grid_y, color):
    x = GRID_SIZE // 2 + grid_x * GRID_SIZE
    y = GRID_SIZE // 2 + grid_y * GRID_SIZE
    pygame.draw.circle(screen, color, (x, y), GRID_SIZE // 2 - 2)

# 判断胜利条件
def check_win(board, row, col):
    directions = [(0, 1), (1, 0), (1, 1), (1, -1)]
    for d in directions:
        count = 1
        for i in range(1, 5):
            r = row + i * d[0]
            c = col + i * d[1]
            if r < 0 or r >= BOARD_SIZE or c < 0 or c >= BOARD_SIZE or board[r][c] != board[row][col]:
                break
            count += 1
        for i in range(1, 5):
            r = row - i * d[0]
            c = col - i * d[1]
            if r < 0 or r >= BOARD_SIZE or c < 0 or c >= BOARD_SIZE or board[r][c] != board[row][col]:
                break
            count += 1
        if count >= 5:
            return True
    return False

# 初始化游戏状态
board = [[0] * BOARD_SIZE for _ in range(BOARD_SIZE)]
current_player = 1
game_over = False
winner = None

# 游戏循环
while True:

    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()
        elif event.type == pygame.MOUSEBUTTONDOWN and not game_over:
            x, y = event.pos
            grid_x, grid_y = x // GRID_SIZE, y // GRID_SIZE
            if board[grid_y][grid_x] == 0:
                place_piece(grid_x, grid_y, BLACK if current_player == 1 else WHITE)
                board[grid_y][grid_x] = current_player
                if check_win(board, grid_y, grid_x):
                    game_over = True
                    winner = current_player
                else:
                    current_player = 2 if current_player == 1 else 1

    # 绘制游戏界面
    screen.fill(WHITE)
    draw_board()
    for y in range(BOARD_SIZE):
        for x in range(BOARD_SIZE):
            if board[y][x] == 1:
                place_piece(x, y, BLACK)
            elif board[y][x] == 2:
                place_piece(x, y, WHITE)
    if game_over:
        font = pygame.font.SysFont(None, 48)
        text = font.render("Player " + str(winner) + " wins!", True, BLACK)
        screen.blit(text, (SCREEN_WIDTH // 2 - text.get_width() // 2, SCREEN_HEIGHT // 2 - text.get_height() // 2))
    pygame.display.update()

这个程序使用了 Pygame 库来实现游戏界面和交互。程序初始化了游戏状态，然后在游戏循环中处理游戏事件，绘制游戏界面，并检查胜利条件。游戏界面由一个棋盘和棋子组成，棋盘是由若干个格子组成的，每个格子大小为 `GRID_SIZE`，棋子半径为 `GRID_SIZE // 2 - 2`。棋盘的大小和格子大小都可以通过调整常量来修改。棋盘上的每个格子被保存在一个二维数组 `board` 中，初始值为 0，表示该格子为空。玩家下棋时，程序会检查该位置是否为空，如果是，则绘制该玩家的棋子，并将该位置的值设为该玩家的编号（1 或 2）。下棋后，程序会检查胜利条件，如果满足条件，则游戏结束，记录胜利者。游戏结束后，程序会在界面上显示胜利者的信息。
