一、开发环境&需求分析
开发环境 ：Windows10 Python3.6.
第三方库 ：Pygame1.9.6
IDE ：PyCharm/Sublime Text
需求分析：
- UI界面
- 玩家与电脑胜负的断定
- 游戏逻辑
- 棋盘、星位和天元
- 网格线、信息文本绘制
- 鼠标事件的判定
二、功能模块
第三方库的导入：
import sys
import random
import pygame
from pygame.locals import *
import pygame.gfxdraw
from collections import namedtuple
游戏初始化及全局变量定义：
pygame.init()
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption('五子棋')
font1 = pygame.font.SysFont('SimHei', 32)
font2 = pygame.font.SysFont('SimHei', 72)
fwidth, fheight = font2.size('黑方获胜')
SIZE = 30 # 棋盘每个点时间的间隔
Line_Points = 19 # 棋盘每行/每列点数
Outer_Width = 20 # 棋盘外宽度
Border_Width = 4 # 边框宽度
Inside_Width = 4 # 边框跟实际的棋盘之间的间隔
Border_Length = SIZE * (Line_Points - 1) + Inside_Width * 2 + Border_Width # 边框线的长度
Start_X = Start_Y = Outer_Width + int(Border_Width / 2) + Inside_Width # 网格线起点（左上角）坐标
SCREEN_HEIGHT = SIZE * (Line_Points - 1) + Outer_Width * 2 + Border_Width + Inside_Width * 2 # 游戏屏幕的高
SCREEN_WIDTH = SCREEN_HEIGHT + 200 # 游戏屏幕的宽
Stone_Radius = SIZE // 2 - 3 # 棋子半径
Stone_Radius2 = SIZE // 2 + 3
Checkerboard_Color = (0xE3, 0x92, 0x65) # 棋盘颜色
BLACK_COLOR = (0, 0, 0)
WHITE_COLOR = (255, 255, 255)
RED_COLOR = (200, 30, 30)
BLUE_COLOR = (30, 30, 200)
胜负判定：
# 判断是否赢了
def _win(self, point):
cur_value = self._checkerboard[point.Y][point.X]
for os in offset:
if self._get_count_on_direction(point, cur_value, os[0], os[1]):
return True
画棋子：
def _draw_chessman(screen, point, stone_color):
# pygame.draw.circle(screen, stone_color, (Start_X + SIZE * point.X, Start_Y + SIZE * point.Y), Stone_Radius)
pygame.gfxdraw.aacircle(screen, Start_X + SIZE * point.X, Start_Y + SIZE * point.Y, Stone_Radius, stone_color)
pygame.gfxdraw.filled_circle(screen, Start_X + SIZE * point.X, Start_Y + SIZE * point.Y, Stone_Radius, stone_color)
鼠标事件判定：
# 根据鼠标点击位置，返回游戏区坐标
def _get_clickpoint(click_pos):
pos_x = click_pos[0] - Start_X
pos_y = click_pos[1] - Start_Y
if pos_x < -Inside_Width or pos_y < -Inside_Width:
return None
x = pos_x // SIZE
y = pos_y // SIZE
if pos_x % SIZE > Stone_Radius:
x += 1
if pos_y % SIZE > Stone_Radius:
y += 1
if x >= Line_Points or y >= Line_Points:
return None
return Point(x, y)
棋盘、网格线、背景色：
def _draw_checkerboard(screen):
# 填充棋盘背景色
screen.fill(Checkerboard_Color)
# 画棋盘网格线外的边框
pygame.draw.rect(screen, BLACK_COLOR, (Outer_Width, Outer_Width, Border_Length, Border_Length), Border_Width)
# 画网格线
for i in range(Line_Points):
pygame.draw.line(screen, BLACK_COLOR,
(Start_Y, Start_Y + SIZE * i),
(Start_Y + SIZE * (Line_Points - 1), Start_Y + SIZE * i),
1)
for j in range(Line_Points):
pygame.draw.line(screen, BLACK_COLOR,
(Start_X + SIZE * j, Start_X),
(Start_X + SIZE * j, Start_X + SIZE * (Line_Points - 1)),
1)
右侧信息显示：
# 画右侧信息显示
def _draw_left_info(screen, font, cur_runner, black_win_count, white_win_count):
_draw_chessman_pos(screen, (SCREEN_HEIGHT + Stone_Radius2, Start_X + Stone_Radius2), BLACK_CHESSMAN.Color)
_draw_chessman_pos(screen, (SCREEN_HEIGHT + Stone_Radius2, Start_X + Stone_Radius2 * 4), WHITE_CHESSMAN.Color)
print_text(screen, font, RIGHT_INFO_POS_X, Start_X + 3, '玩家', BLUE_COLOR)
print_text(screen, font, RIGHT_INFO_POS_X, Start_X + Stone_Radius2 * 3 + 3, '电脑', BLUE_COLOR)
print_text(screen, font, SCREEN_HEIGHT, SCREEN_HEIGHT - Stone_Radius2 * 8, '战况：', BLUE_COLOR)
_draw_chessman_pos(screen, (SCREEN_HEIGHT + Stone_Radius2, SCREEN_HEIGHT - int(Stone_Radius2 * 4.5)), BLACK_CHESSMAN.Color)
_draw_chessman_pos(screen, (SCREEN_HEIGHT + Stone_Radius2, SCREEN_HEIGHT - Stone_Radius2 * 2), WHITE_CHESSMAN.Color)
print_text(screen, font, RIGHT_INFO_POS_X, SCREEN_HEIGHT - int(Stone_Radius2 * 5.5) + 3, f'{
black_win_count} 胜', BLUE_COLOR)
print_text(screen, font, RIGHT_INFO_POS_X, SCREEN_HEIGHT - Stone_Radius2 * 3 + 3, f'{
white_win_count} 胜', BLUE_COLOR)
电脑AI类：
class AI:
def __init__(self, line_points, chessman):
self._line_points = line_points
self._my = chessman
self._opponent = BLACK_CHESSMAN if chessman == WHITE_CHESSMAN else WHITE_CHESSMAN
self._checkerboard = [[0] * line_points for _ in range(line_points)]
def get_opponent_drop(self, point):
self._checkerboard[point.Y][point.X] = self._opponent.Value
def AI_drop(self):
point = None
score = 0
for i in range(self._line_points):
for j in range(self._line_points):
if self._checkerboard[j][i] == 0:
_score = self._get_point_score(Point(i, j))
if _score > score:
score = _score
point = Point(i, j)
elif _score == score and _score > 0:
r = random.randint(0, 100)
if r % 2 == 0:
point = Point(i, j)
self._checkerboard[point.Y][point.X] = self._my.Value
return point
游戏主循环：
while True:
for event in pygame.event.get():
if event.type == QUIT:
sys.exit()
elif event.type == KEYDOWN:
if event.key == K_RETURN:
if winner is not None:
winner = None
cur_runner = BLACK_CHESSMAN
checkerboard = Checkerboard(Line_Points)
computer = AI(Line_Points, WHITE_CHESSMAN)
elif event.type == MOUSEBUTTONDOWN:
if winner is None:
pressed_array = pygame.mouse.get_pressed()
if pressed_array[0]:
mouse_pos = pygame.mouse.get_pos()
click_point = _get_clickpoint(mouse_pos)
if click_point is not None:
if checkerboard.can_drop(click_point):
winner = checkerboard.drop(cur_runner, click_point)
if winner is None:
cur_runner = _get_next(cur_runner)
computer.get_opponent_drop(click_point)
AI_point = computer.AI_drop()
winner = checkerboard.drop(cur_runner, AI_point)
if winner is not None:
white_win_count += 1
cur_runner = _get_next(cur_runner)
else:
black_win_count += 1
else:
print('超出棋盘区域')
