pythonpygame实现五子棋小游戏

今天学习了如何使⽤pygame来制作⼩游戏，下⾯是五⼦棋的代码，我的理解都写在注释⾥了

import pygame# 导⼊pygame模块print(pygame.ver)

# 检查pygame的版本，检查pygame有没有导⼊成功EMPTY = 0BLACK = 1WHITE = 2

# 定义三个常量函数，⽤来表⽰⽩棋，⿊棋，以及 空black_color = [0, 0, 0]

# 定义⿊⾊（⿊棋⽤，画棋盘）white_color = [255, 255, 255]# 定义⽩⾊（⽩棋⽤）# 定义棋盘这个类

class RenjuBoard(object):

def __init__(self):

# self._board = board = [[EMPTY] * 15 for _ in range(15)]

# 将棋盘每⼀个交叉点都看作列表的⼀个元素位，⼀共有15*15共225个元素 self._board = [[]] * 15 self.reset() #重置棋盘 def reset(self):

for row in range(len(self._board)): self._board[row] = [EMPTY] * 15

#定义棋盘上的下棋函数，row表⽰⾏，col表⽰列，is_black表⽰判断当前点位该下⿊棋，还是⽩棋 def move(self, row, col, is_black): if self._board[row][col] == EMPTY:

self._board[row][col] = BLACK if is_black else WHITE return True return False

# 给棋盘定义⼀个函数将⾃⼰在screen上⾯画出来，使⽤pygame.draw()函数。并且顺便将下了的棋⼦也画出来 def draw(self, screen): for h in range(1, 16):

pygame.draw.line(screen, black_color, [40, h * 40], [600, h * 40], 1)

pygame.draw.line(screen, black_color, # 给棋盘加⼀个外框，使美观

pygame.draw.rect(screen, black_color, [36, 36, 568, 568], 3) # 在棋盘上标出，天元以及另外4个特殊点位

pygame.draw.circle(screen, black_color, [320, 320], 5, 0) pygame.draw.circle(screen, black_color, [160, 160], 3, 0) pygame.draw.circle(screen, black_color, [160, 480], 3, 0) pygame.draw.circle(screen, black_color, [480, 160], 3, 0) pygame.draw.circle(screen, black_color, [480, 480], 3, 0) #做2次for循环取得棋盘上所有交叉点的坐标 for row in range(len(self._board)): for col in range(len(self._board[row])): # 将下在棋盘上的棋⼦画出来

if self._board[row][col] != EMPTY: ccolor = black_color \\

if self._board[row][col] == BLACK else white_color # 取得这个交叉点下的棋⼦的颜⾊，并将棋⼦画出来 pos = [40 * (col + 1), 40 * (row + 1)] # 画出棋⼦

pygame.draw.circle(screen, ccolor, pos, 18, 0)

# 定义函数，传⼊当前棋盘上的棋⼦列表，输出结果，不管⿊棋⽩棋胜，都是传回False，未出结果则为Truedef is_win(board): for n in range(15): # 判断垂直⽅向胜利 flag = 0

# flag是⼀个标签，表⽰是否有连续以上五个相同颜⾊的棋⼦ for b in board._board: if b[n] == 1: flag += 1 if flag == 5: print('⿊棋胜') return False else:

# else表⽰此时没有连续相同的棋⼦，标签flag重置为0 flag = 0

flag = 0

for b in board._board: if b[n] == 2: flag += 1 if flag == 5: print('⽩棋胜') return False else: flag = 0

# 判断⽔平⽅向胜利 flag = 0

for b in board._board[n]: if b == 1: flag += 1 if flag == 5: print('⿊棋胜') return False else: flag = 0

flag = 0

for b in board._board[n]: if b == 2: flag += 1 if flag == 5: print('⽩棋胜') return False else: flag = 0

# 判断正斜⽅向胜利

for x in range(4, 25): flag = 0

for i,b in enumerate(board._board): if 14 >= x - i >= 0 and b[x - i] == 1: flag += 1 if flag == 5: print('⿊棋胜') return False else:

flag = 0

for x in range(4, 25): flag = 0

for i,b in enumerate(board._board): if 14 >= x - i >= 0 and b[x - i] == 2: flag += 1 if flag == 5: print('⽩棋胜') return False else: flag = 0

#判断反斜⽅向胜利

for x in range(11, -11, -1): flag = 0

for i,b in enumerate(board._board): if 0 <= x + i <= 14 and b[x + i] == 1: flag += 1 if flag == 5: print('⿊棋胜') return False else: flag = 0

for x in range(11, -11, -1): flag = 0

for i,b in enumerate(board._board): if 0 <= x + i <= 14 and b[x + i] == 2: flag += 1 if flag == 5: print('⽩棋胜') return False else: flag = 0 return True

def main():

# 创建棋盘对象

board = RenjuBoard()

# ⽤于判断是下⿊棋还是⽩棋 is_black = True

# pygame初始化函数，固定写法 pygame.init()

pygame.display.set_caption('五⼦棋') # 改标题

# pygame.display.set_mode()表⽰建⽴个窗⼝，左上⾓为坐标原点，往右为x正向，往下为y轴正向 screen = pygame.display.set_mode((640,640)) # 给窗⼝填充颜⾊，颜⾊⽤三原⾊数字列表表⽰ screen.fill([125,95,24])

board.draw(screen) # 给棋盘类发命令，调⽤draw()函数将棋盘画出来 pygame.display.flip() # 刷新窗⼝显⽰ running = True

# while 主循环的标签，以便跳出循环 while running:

# 遍历建⽴窗⼝后发⽣的所有事件，固定写法 for event in pygame.event.get(): # 根据事件的类型，进⾏判断 if event.type == pygame.QUIT: running = False

elif event.type == pygame.KEYUP: pass

# pygame.MOUSEBUTTONDOWN表⽰⿏标的键被按下 elif event.type == pygame.MOUSEBUTTONDOWN and \\ event.button == 1:# button表⽰⿏标左键

x, y = event.pos # 拿到⿏标当前在窗⼝上的位置坐标 # 将⿏标的(x, y)窗⼝坐标，转化换为棋盘上的坐标 row = round((y - 40) / 40) col = round((x - 40) / 40)

if board.move(row, col, is_black): is_black = not is_black screen.fill([125, 95, 24]) board.draw(screen) pygame.display.flip() # 调⽤判断胜负函数 if not is_win(board): #break

running = False

# 这⾥我有个bug没找到解决办法，就是判断出胜负后，使⽤break跳出事件遍历的for循环，但是⽼是不能跳出来，导致胜负分出来了还可以继续下，这⾥我采⽤判断胜负后就将running标签赋值为False，跳出主循环，但是这样棋盘的窗⼝也没了。明天再找找bug在 pygame.quit()

if __name__ == '__main__': main()
