簡介

使用python實現pygame版的五子棋游戲；

環境：Windows系統+python3.8.0

游戲規則：

1.分兩位棋手對戰，默認黑棋先下；當在棋盤點擊左鍵，即在該位置繪制黑棋；

2.自動切換到白棋，當在棋盤點擊左鍵，即在該位置繪制白棋；

3.輪流切換棋手下棋，當那方先形成5子連線者獲勝（橫、豎、斜、反斜四個方向都可以）。

游戲運行效果如下：

實現過程

1.新建文件settings.py，用來定義一些必須的基本屬性和初始值；

class Settings():

def __init__(self):

"""初始化的游戲配置"""

# 屏幕寬高

self.width = 700

self.height = 554

# 文字顏色和大小

self.fontsize = 14

self.fonttype = 'simsunnsimsun'

# 棋盤格數

self.number = 15

# 棋盤左邊距、上邊距和間隔

self.bd_left = 30

self.bd_top = 30

self.bd_space = 36

# 判斷游戲是否結束（默認開始）

self.game_active = True

# 判斷哪方下棋（默認黑子先寫）

self.chess_player = 1

self.prompt_info = '當前棋手：黑棋'

# 開始校驗輸贏（兩邊合計9，因為已經有一邊5步）

self.win_number = 0

# 設置背景圖、黑棋圖片、白棋圖片路徑

self.checkerboard_bg = 'images/checkerboard_bg.png'

self.black_chess = 'images/black_chess.png'

self.white_chess = 'images/white_chess.png'

# 存儲落子數據

self.move_chess = []

2.新建文件checkerboard.py，主要用來繪制背景圖和棋格線；

import sys

import pygame

class Checkerboard():

def __init__(self, ck_settings, screen, position):

self.ck_settings = ck_settings

self.screen = screen

self.position = position

# 顏色和坐標大小

self.text_color = (0, 0, 0)

self.font = pygame.font.SysFont(ck_settings.fonttype, ck_settings.fontsize)

# 存儲棋子坐標

self.checkerboard = []

# 加載背景圖、黑棋和白棋（當有圖片不存在時，打印錯誤并退出游戲）

try:

self.bg_image = pygame.image.load(ck_settings.checkerboard_bg)

self.black_image = pygame.image.load(ck_settings.black_chess).convert_alpha() # convert_alpha背景透明

self.white_image = pygame.image.load(ck_settings.white_chess).convert_alpha()

self.chess_rect = self.black_image.get_rect()

except Exception as e:

print('error:', e)

sys.exit()

def draw_board(self):

# 存儲棋子坐標

for i in range(self.ck_settings.number):

self.checkerboard.append([])

for j in range(self.ck_settings.number):

self.checkerboard[i].append(self.position(self.ck_settings.bd_left + i * self.ck_settings.bd_space, self.ck_settings.bd_top + j * self.ck_settings.bd_space))

# 繪制棋盤坐標

for i in range(0, self.ck_settings.number):

# ord返回字符的ASCII數值，chr再返回字符

x_text = self.font.render(chr(ord('A') + i), True, self.text_color) # A-O

y_text = self.font.render(str(i + 1), True, self.text_color) # 1-15

# 繪制xy軸坐標（在棋盤背景圖繪制）

self.bg_image.blit(x_text, (self.checkerboard[i][0].x - x_text.get_width() / 2, self.checkerboard[i][0].y - 20))

self.bg_image.blit(y_text, (self.checkerboard[0][i].x - 20, self.checkerboard[0][i].y - y_text.get_height() / 2))

# 繪制橫豎線（在棋盤背景圖繪制）

pygame.draw.line(self.bg_image, self.text_color, self.checkerboard[0][i], self.checkerboard[self.ck_settings.number-1][i])

pygame.draw.line(self.bg_image, self.text_color, self.checkerboard[i][0], self.checkerboard[i][self.ck_settings.number-1])

# 繪制棋盤背景圖

self.screen.blit(self.bg_image, (0, 0))

3.新建文件infopanel.py，主要用來繪制棋盤右邊提示信息（暫時只有顯示下棋方和獲勝信息）；

import pygame.font

class Infopanel():

def __init__(self, ck_settings, screen):

"""初始化屬性"""

self.settings = ck_settings

self.screen = screen

self.screen_rect = screen.get_rect()

# 設置文字顏色和字體大小

self.info_color = (217, 8, 10)

self.font = pygame.font.SysFont(ck_settings.fonttype, 16)

def draw_info(self, info):

"""將文字渲染為圖像，并定位到右邊水平居中"""

self.info_image = self.font.render(info, True, self.info_color)

self.info_image_rect = self.info_image.get_rect()

self.info_image_rect.right = self.screen_rect.right - (self.screen_rect.width - 536 - self.info_image_rect.width) / 2

self.info_image_rect.top = 50

# 繪制到屏幕

self.screen.blit(self.info_image, self.info_image_rect)

4.新建文件“game_functions.py”，存放跟游戲有關的所有業務邏輯函數；

import sys

import pygame

# 棋

def update_board(ck_settings, cb, index_coordinates, position):

"""更新棋盤信息"""

# 判斷棋手（黑棋或白棋）

if ck_settings.chess_player == 1:

ck_settings.prompt_info = '當前棋手：白棋'

img = cb.black_image

chess_type = 'black'

else:

ck_settings.prompt_info = '當前棋手：黑棋'

img = cb.white_image

chess_type = 'white'

"""落棋"""

dropState = check_at(ck_settings, index_coordinates)

if dropState:

i, j = index_coordinates

chess_x = cb.checkerboard[j][i].x - cb.chess_rect.width / 2

chess_y = cb.checkerboard[j][i].y - cb.chess_rect.height / 2

# 累計步數（兩邊合計）

ck_settings.win_number += 1

# 落子并轉換棋手

ck_settings.move_chess.append({'type': chess_type, 'coord': position(i, j)})

cb.bg_image.blit(img, (chess_x, chess_y))

ck_settings.chess_player *= -1

# 合計9步開始校驗輸贏

if ck_settings.win_number >= 9:

check_stats(ck_settings, (i, j))

else:

ck_settings.prompt_info = '已經有其他棋子'

# 檢查(i,j)位置是否已占用

def check_at(ck_settings, index_coordinates):

for item in ck_settings.move_chess:

if index_coordinates == item['coord']:

return False

return True

def check_stats(ck_settings, pos):

"""校驗四個方向，是否有了輸贏"""

pos_i, pos_j = pos

directs = [(1, 0), (0, 1), (1, 1), (1, -1)] # 橫、豎、斜、反斜 四個方向檢查

for direct in directs:

line_checkerboard = []

d_x, d_y = direct

last = ck_settings.move_chess[-1]

line_ball = [] # 存放在一條線上的棋子

for ball in ck_settings.move_chess:

# 跟最后落子判斷

if ball['type'] == last['type']:

x = ball['coord'].x - last['coord'].x

y = ball['coord'].y - last['coord'].y

if d_x == 0:

if x == 0:

line_ball.append(ball['coord'])

if d_y == 0:

if y == 0:

line_ball.append(ball['coord'])

if x * d_y == y * d_x:

line_ball.append(ball['coord'])

if len(line_ball) >= 5: # 只有5子及以上才繼續判斷

sorted_line = sorted(line_ball)

for i, item in enumerate(sorted_line):

index = i + 4

if index < len(sorted_line):

if d_x == 0:

y1 = item.y

y2 = sorted_line[index].y

# 此點和第5個點比較y值，如相差為4則連成5子

if abs(y1 - y2) == 4:

ck_settings.prompt_info = '黑棋獲勝' if last['type'] == 'black' else '白棋獲勝'

else:

x1 = item.x

x2 = sorted_line[index].x

# 此點和第5個點比較x值，如相差為4則連成5子

if abs(x1 - x2) == 4:

ck_settings.prompt_info = '黑棋獲勝' if last['type'] == 'black' else '白棋獲勝'

else:

break

# 事件

def check_events(ck_settings, cb, position):

"""監聽事件"""

for event in pygame.event.get():

if event.type == pygame.QUIT:

sys.exit()

elif event.type == pygame.MOUSEBUTTONDOWN:

# 點擊左鍵

if event.button == 1:

pos = pygame.mouse.get_pos() # 獲取點擊實際坐標

# 判斷是否溢出

x_first = cb.checkerboard[0][0].x

x_last = cb.checkerboard[ck_settings.number - 1][ck_settings.number - 1].x

y_first = cb.checkerboard[0][0].y

y_last = cb.checkerboard[ck_settings.number - 1][ck_settings.number - 1].y

if pos[0] < x_first or pos[0] > x_last or pos[1] < y_first or pos[1] > y_last:

ck_settings.prompt_info = '落子位置不正確！'

else:

index_coordinates = to_index(ck_settings, pos)

update_board(ck_settings, cb, index_coordinates, position)

def to_index(ck_settings, pos):

"""實際坐標轉換為棋盤下標"""

i = round((pos[1] - ck_settings.bd_top) / ck_settings.bd_space)

j = round((pos[0] - ck_settings.bd_left) / ck_settings.bd_space)

return (i, j)

5.新建文件gobang.py，主函數用來初始化程序，并同步更新程序的信息；

import pygame

from settings import Settings

from checkerboard import Checkerboard

from collections import namedtuple

import game_functions as gf

from infopanel import Infopanel

def run_game():

"""運行游戲"""

# 初始化游戲屏幕

pygame.init()

# 創建時鐘對象 (可以控制游戲循環頻率)

clock = pygame.time.Clock()

# 配置實例化

ck_settings = Settings()

screen = pygame.display.set_mode((ck_settings.width, ck_settings.height))

pygame.display.set_caption('五子棋游戲')

# namedtuple創建類似于元組的數據類型，除了可以用索引訪問，能夠迭代，還能用屬性名訪問數據

position = namedtuple('Position', ['x', 'y'])

# 創建實例

cb = Checkerboard(ck_settings, screen, position)

# 實例化面板信息

infopanel = Infopanel(ck_settings, screen)

while ck_settings.game_active:

# 繪制棋盤

cb.draw_board()

# 繪制面板信息

infopanel.draw_info(ck_settings.prompt_info)

# 檢查玩家事件并更新棋盤

gf.check_events(ck_settings, cb, position)

# 讓最近繪制的屏幕可見

pygame.display.flip()

# 通過時鐘對象指定循環頻率

clock.tick(60) # 每秒循環60次

run_game()

6.在文件gobang.py目錄路徑下，執行命令“python gobang.py”彈出窗口，即可對其操作游玩。

結語

該游戲只是實現了基礎功能，還有很多可優化的功能：

1.根據實際情況加上更詳細的面板信息（比如倒計時等）；

2.加上開始游戲按鈕，可參考前面python實例；

3.勝負榜單等，可參考前面python實例。
