前言

周末了，咱们来玩玩五子棋陶冶情操。快拿这个和你女朋友去对线。（分了别来找我哇）。多的不说直接进入正题

人人对战

游戏规则：p1为黑子，p2为白子，黑子先手，一方达到五子相连即为获胜。

动态演示

源码分享

cheackboard.py

定义黑白子，落子位置以及获胜规则。

from collections import namedtuple

Chessman = namedtuple('Chessman', 'Name Value Color')Point = namedtuple('Point', 'X Y')

BLACK_CHESSMAN = Chessman('黑子', 1, (45, 45, 45))WHITE_CHESSMAN = Chessman('白子', 2, (219, 219, 219))

offset = [(1, 0), (0, 1), (1, 1), (1, -1)]

class Checkerboard: def __init__(self, line_points): self._line_points = line_points self._checkerboard = [[0] * line_points for _ in range(line_points)]

def _get_checkerboard(self): return self._checkerboard

checkerboard = property(_get_checkerboard)

# 判断是否可落子 def can_drop(self, point): return self._checkerboard[point.Y][point.X] == 0

def drop(self, chessman, point): ''' 落子 :param chessman: :param point:落子位置 :return:若该子落下之后即可获胜，则返回获胜方，否则返回 None ''' print(f'{chessman.Name} ({point.X}, {point.Y})') self._checkerboard[point.Y][point.X] = chessman.Value

if self._win(point): print(f'{chessman.Name}获胜') return chessman

# 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

def _get_count_on_direction(self, point, value, x_offset, y_offset): count = 1 for step in range(1, 5): x = point.X + step * x_offset y = point.Y + step * y_offset if 0 <= x < self._line_points and 0 <= y < self._line_points and self._checkerboard[y][x] == value: count += 1 else: break for step in range(1, 5): x = point.X - step * x_offset y = point.Y - step * y_offset if 0 <= x < self._line_points and 0 <= y < self._line_points and self._checkerboard[y][x] == value: count += 1 else: break

return count >= 5

画棋盘

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)    # 画星位和天元    for i in (3, 9, 15):        for j in (3, 9, 15):            if i == j == 9:                radius = 5            else:                radius = 3            # pygame.draw.circle(screen, BLACK, (Start_X + SIZE * i, Start_Y + SIZE * j), radius)            pygame.gfxdraw.aacircle(screen, Start_X + SIZE * i, Start_Y + SIZE * j, radius, BLACK_COLOR)            pygame.gfxdraw.filled_circle(screen, Start_X + SIZE * i, Start_Y + SIZE * j, radius, BLACK_COLOR)

画棋子

运行框返回落子坐标
