Python Pygame 实现五子棋小游戏攻略

简介

五子棋是一种著名的棋类游戏，现在很多人都喜欢通过程序来实现五子棋游戏。本文将介绍如何使用 Python 及 Pygame 库实现五子棋小游戏。

准备工作

在开始编写代码之前，需要安装 Pygame 库。可以使用以下命令安装：

pip install pygame

另外，本文的实现基于Python 3.x版本。读者需要确认是使用Python 3.x版本，否则需要稍作改动。

编写代码

创建界面

import pygame

# 初始化Pygame库
pygame.init()

# 创建窗口
size = width, height = 640, 480
screen = pygame.display.set_mode(size)
pygame.display.set_caption("五子棋")

# 游戏主循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 绘制棋盘
    screen.fill((255, 255, 255))
    pygame.draw.rect(screen, (0, 0, 0), (20, 20, 400, 400), 2)
    for i in range(15):
        pygame.draw.line(screen, (0, 0, 0), (40 + i * 25, 40), (40 + i * 25, 400), 1)
        pygame.draw.line(screen, (0, 0, 0), (40, 40 + i * 25), (400, 40 + i * 25), 1)

    # 刷新屏幕
    pygame.display.flip()

# 结束Pygame库
pygame.quit()

上述代码实现了创建窗口、绘制棋盘以及处理退出事件等功能。

添加游戏逻辑

import pygame

# 初始化Pygame库
pygame.init()

# 创建窗口
size = width, height = 640, 480
screen = pygame.display.set_mode(size)
pygame.display.set_caption("五子棋")

# 定义棋盘大小和棋格大小
BOARD_SIZE = 15
GRID_SIZE = 25
# 初始化棋盘
board = [[0] * BOARD_SIZE for _ in range(BOARD_SIZE)]

# 绘制棋盘
def draw_board():
    screen.fill((255, 255, 255))
    pygame.draw.rect(screen, (0, 0, 0), (20, 20, BOARD_SIZE * GRID_SIZE, BOARD_SIZE * GRID_SIZE), 2)
    for i in range(BOARD_SIZE):
        pygame.draw.line(screen, (0, 0, 0), (40 + i * GRID_SIZE, 40), (40 + i * GRID_SIZE, 40 + (BOARD_SIZE - 1) * GRID_SIZE), 1)
        pygame.draw.line(screen, (0, 0, 0), (40, 40 + i * GRID_SIZE), (40 + (BOARD_SIZE - 1) * GRID_SIZE, 40 + i * GRID_SIZE), 1)

# 绘制棋子
def draw_chess(row, col, player):
    pygame.draw.circle(screen, player, (40 + col * GRID_SIZE, 40 + row * GRID_SIZE), 10)

# 判断胜负
def check_win(row, col, player):
    count = 0
    # 判断行
    for i in range(BOARD_SIZE):
        if board[row][i] == player:
            count += 1
        else:
            count = 0
        if count == 5:
            return True
    # 判断列
    count = 0
    for i in range(BOARD_SIZE):
        if board[i][col] == player:
            count += 1
        else:
            count = 0
        if count == 5:
            return True
    # 判断正斜线
    count = 0
    for i in range(max(row, col) - min(row, col), BOARD_SIZE):
        if board[i - max(row, col) + row][i - max(row, col) + col] == player:
            count += 1
        else:
            count = 0
        if count == 5:
            return True
    # 判断反斜线
    count = 0
    for i in range(row + col - min(row, col)):
        if i < BOARD_SIZE and row + col - i >= 0 and row + col - i < BOARD_SIZE and board[row + col - i][i] == player:
            count += 1
        else:
            count = 0
        if count == 5:
            return True
    return False

# 游戏主循环
player = (0, 0, 0)
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:
            if event.button == 1:
                row = (event.pos[1] - 40) // GRID_SIZE
                col = (event.pos[0] - 40) // GRID_SIZE
                if row >= 0 and row < BOARD_SIZE and col >= 0 and col < BOARD_SIZE and board[row][col] == 0:
                    if player == (0, 0, 0):
                        player = (255, 255, 255)
                    else:
                        player = (0, 0, 0)
                    board[row][col] = player
                    draw_chess(row, col, player)
                    if check_win(row, col, player):
                        print("Player", end=' ')
                        if player == (0, 0, 0):
                            print("1", end=' ')
                        else:
                            print("2", end=' ')
                        print("wins!")

    # 绘制棋盘
    draw_board()
    for i in range(BOARD_SIZE):
        for j in range(BOARD_SIZE):
            if board[i][j] != 0:
                draw_chess(i, j, board[i][j])

    # 刷新屏幕
    pygame.display.flip()

# 结束Pygame库
pygame.quit()

上述代码实现了添加游戏逻辑。主要功能包括：初始画面绘制、绘制棋盘、绘制棋子、判断胜负、处理游戏事件等。

总结

以上便是使用 Python 和 Pygame 库实现五子棋小游戏的完整攻略。希望对大家有所帮助。

示例说明

示例一：在游戏主循环中，判断处理玩家落子的事件

for event in pygame.event.get():
    if event.type == pygame.MOUSEBUTTONDOWN:
        if event.button == 1:  # 1表示鼠标左键
            row = (event.pos[1] - 40) // GRID_SIZE  # 计算所在的行
            col = (event.pos[0] - 40) // GRID_SIZE  # 计算所在的列
            if row >= 0 and row < BOARD_SIZE and col >= 0 and col < BOARD_SIZE and board[row][col] == 0:
                # 该位置没有棋子则可以落子
                player = (255, 255, 255) if player == (0, 0, 0) else (0, 0, 0)  # 切换当前落子方
                board[row][col] = player  # 在棋盘上标记该位置有该玩家的棋子
                draw_chess(row, col, player)  # 绘制该棋子
                if check_win(row, col, player):  # 判断是否有玩家胜利
                    print("Player", end=' ')
                    if player == (0, 0, 0):
                        print("1", end=' ')
                    else:
                        print("2", end=' ')
                    print("wins!")

示例二：判断胜负的函数check_win()

def check_win(row, col, player):
    count = 0
    # 判断行
    for i in range(BOARD_SIZE):
        if board[row][i] == player:
            count += 1
        else:
            count = 0
        if count == 5:
            return True
    # 判断列
    count = 0
    for i in range(BOARD_SIZE):
        if board[i][col] == player:
            count += 1
        else:
            count = 0
        if count == 5:
            return True
    # 判断正斜线
    count = 0
    for i in range(max(row, col) - min(row, col), BOARD_SIZE):
        if board[i - max(row, col) + row][i - max(row, col) + col] == player:
            count += 1
        else:
            count = 0
        if count == 5:
            return True
    # 判断反斜线
    count = 0
    for i in range(row + col - min(row, col)):
        if i < BOARD_SIZE and row + col - i >= 0 and row + col - i < BOARD_SIZE and board[row + col - i][i] == player:
            count += 1
        else:
            count = 0
        if count == 5:
            return True
    return False

以上是两个关键的示例。在游戏中，可以通过玩家的落子事件和胜负的判断来完整实现五子棋小游戏。
