Pygame实战练习之纸牌21点游戏(红桃黑桃)

导语

昨天不是周天嘛？

你们在家放松一般都会做什么呢？

周末逛逛街，出去走走看电影......这是你们的周末。

程序员的周末就是在家躺尸唐诗躺尸，偶尔加班加班加班，或者跟着几个朋友在家消遣时间打打麻将，扑克牌玩一下！

尤其是放长假【ps:也没啥假，长假就是过年】在老家的时候，亲戚尤其多，七大姑八大姨的一年好不容易聚一次，打打麻将跟扑克这是常有的事儿，联络下感情这是最快的方式~

说起打扑克，我们经常就是玩儿的二百四、炸金花、三个打一个那就是叫啥名字来着，容我想想......

话说真词穷，我们那都是方言撒，我翻译不过来普通话是叫什么了，我估计240你们也没听懂是啥，23333~

今天的话小编是带大家做一款21点的扑克游戏！

有大佬可优化一下这个代码，做一个精致豪华的界面就好了~~

游戏规则：21点又名黑杰克，该游戏由2到6个人玩，使用除大小王之外的52张牌，游戏者的目标是使手中的牌的点数之和不超过21点且尽量大。当使用1副牌时，以下每种牌各一张（没有大小王）：

（1）初始化玩家数：

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def iniGame():
 global playerCount, cards
 while(True):
  try:
playerCount = int(input('输入玩家数：'))
  except ValueError:
print('无效输入！')
continue
  if playerCount < 2:
print('玩家必须大于1！')
continue
  else:
break
 try:
  decks = int(input('输入牌副数：（默认等于玩家数）'))
 except ValueError:
  print('已使用默认值！')
  decks = playerCount
 print('玩家数：', playerCount, '，牌副数：', decks)
 cards = getCards(decks)  # 洗牌</span></span></span>

（2）建立了玩家列表，电脑跟玩家对战。

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def createPlayerList():
 global playerList
 playerList = []
 for i in range(playerCount):
  playerList += [{'id': '', 'cards': [], 'score': 0}].copy()
  playerList[i]['id'] = '电脑' + str(i+1)
 playerList[playerCount-1]['id'] = '玩家'
 random.shuffle(playerList)  # 为各玩家随机排序</span></span></span>

（3）开始会设置2张明牌玩法都可以看到点数。

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def gameStart():
 print('为各玩家分2张明牌：')
 for i in range(playerCount):  # 为每个玩家分2张明牌
  deal(playerList[i]['cards'], cards, 2)
  playerList[i]['score'] = getScore(playerList[i]['cards'])  # 计算初始得分
  print(playerList[i]['id'], ' ', getCardName(playerList[i]['cards']),
  ' 得分 ', playerList[i]['score'])
  time.sleep(1.5)</span></span></span>

（4）游戏为电脑跟玩家依次分发第三张暗牌，这是别人看不到的。

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def gamePlay():
 for i in range(playerCount):
  print('当前', playerList[i]['id'])
  if playerList[i]['id'] == '玩家':  # 玩家
while(True):
 print('当前手牌：', getCardName(playerList[i]['cards']))
 _isDeal = input('是否要牌？（y/n）')
 if _isDeal == 'y':
  deal(playerList[i]['cards'], cards)
  print('新牌：', getCardName(playerList[i]['cards'][-1]))
  # 重新计算得分:
  playerList[i]['score'] = getScore(playerList[i]['cards'])
 elif _isDeal == 'n':
  break
 else:
  print('请重新输入！')
  else:  # 电脑
while(True):
 if isDeal(playerList[i]['score']) == 1:  # 为电脑玩家判断是否要牌
  deal(playerList[i]['cards'], cards)
  print('要牌。')
  # 重新计算得分:
  playerList[i]['score'] = getScore(playerList[i]['cards'])
 else:
  print('不要了。')
  break
  time.sleep(1.5)</span></span></span>

（5）随机洗牌：

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def getCards(decksNum):
 cardsList = ['Aa', 'Ab', 'Ac', 'Ad',
  'Ka', 'Kb', 'Kc', 'Kd',
  'Qa', 'Qb', 'Qc', 'Qd',
  'Ja', 'Jb', 'Jc', 'Jd',
  '0a', '0b', '0c', '0d',
  '9a', '9b', '9c', '9d',
  '8a', '8b', '8c', '8d',
  '7a', '7b', '7c', '7d',
  '6a', '6b', '6c', '6d',
  '5a', '5b', '5c', '5d',
  '4a', '4b', '4c', '4d',
  '3a', '3b', '3c', '3d',
  '2a', '2b', '2c', '2d']
 cardsList *= decksNum # 牌副数
 random.shuffle(cardsList)# 随机洗牌
 return cardsList</span></span></span>

（6）设置牌名字典：

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">cardNameDict = {'Aa': '黑桃A', 'Ab': '红桃A', 'Ac': '梅花A', 'Ad': '方片A',
 'Ka': '黑桃K', 'Kb': '红桃K', 'Kc': '梅花K', 'Kd': '方片K',
 'Qa': '黑桃Q', 'Qb': '红桃Q', 'Qc': '梅花Q', 'Qd': '方片Q',
 'Ja': '黑桃J', 'Jb': '红桃J', 'Jc': '梅花J', 'Jd': '方片J',
 '0a': '黑桃10', '0b': '红桃10', '0c': '梅花10', '0d': '方片10',
 '9a': '黑桃9', '9b': '红桃9', '9c': '梅花9', '9d': '方片9',
 '8a': '黑桃8', '8b': '红桃8', '8c': '梅花8', '8d': '方片8',
 '7a': '黑桃7', '7b': '红桃7', '7c': '梅花7', '7d': '方片7',
 '6a': '黑桃6', '6b': '红桃6', '6c': '梅花6', '6d': '方片6',
 '5a': '黑桃5', '5b': '红桃5', '5c': '梅花5', '5d': '方片5',
 '4a': '黑桃4', '4b': '红桃4', '4c': '梅花4', '4d': '方片4',
 '3a': '黑桃3', '3b': '红桃3', '3c': '梅花3', '3d': '方片3',
 '2a': '黑桃2', '2b': '红桃2', '2c': '梅花2', '2d': '方片2'}</span></span></span>

（7）判断胜负：

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def showWinAndLose():
 loserList = []  # [['id', score], ['id', score], ...]
 winnerList = []  # [['id', score], ['id', score], ...]
 winnerCount = 0
 loserCount = 0
 for i in range(playerCount):
  if playerList[i]['score'] > 21:  # 爆牌直接进入败者列表
loserList.append([playerList[i]['id'],  playerList[i]['score']])
  else:  # 临时胜者列表
winnerList.append([playerList[i]['id'], playerList[i]['score']])
 if len(winnerList) == 0:  # 极端情况：全部爆牌
  print('全部玩家爆牌：')
  for i in range(len(loserList)):
print(loserList[i][0], loserList[i][1])
 elif len(loserList) == 0:  # 特殊情况：无人爆牌
  winnerList.sort(key=lambda x: x[1], reverse=True)  # 根据分数值排序胜者列表
  for i in range(len(winnerList)):  # 计算最低分玩家数量
if i != len(winnerList)-1:
 if winnerList[-i-1][1] == winnerList[-i-2][1]:
  loserCount = (i+2)
 else:
  if loserCount == 0:loserCount = 1
  break
else:
 loserCount = len(loserList)
  if loserCount == 1:
loserList.append(winnerList.pop())
  else:
while(len(loserList) != loserCount):
 loserList.append(winnerList.pop())
  for i in range(len(winnerList)):  # 计算最高分玩家数量
if i != len(winnerList)-1:
 if winnerList[i][1] == winnerList[i+1][1]:
  winnerCount = (i+2)
 else:
  if winnerCount == 0:winnerCount = 1
  break
else:
 winnerCount = len(winnerList)
  while(len(winnerList) != winnerCount):
winnerList.pop()
  print('获胜：')
  for i in range(len(winnerList)):
print(winnerList[i][0], winnerList[i][1])
  print('失败：')
  for i in range(len(loserList)):
print(loserList[i][0], loserList[i][1])
 else:  # 一般情况：有人爆牌
  winnerList.sort(key=lambda x: x[1], reverse=True)  # 根据分数值排序胜者列表
  for i in range(len(winnerList)):  # 计算最高分玩家数量
if i != len(winnerList)-1:
 if winnerList[i][1] == winnerList[i+1][1]:
  winnerCount = (i+2)
 else:
  if winnerCount == 0:winnerCount = 1
  break
else:
 winnerCount = len(winnerList)
  while(len(winnerList) != winnerCount):
winnerList.pop()
  print('获胜：')
  for i in range(len(winnerList)):
print(winnerList[i][0], winnerList[i][1])
  print('失败：')
  for i in range(len(loserList)):
print(loserList[i][0], loserList[i][1])</span></span></span>

游戏效果：咳咳咳.......感觉这游戏看运气也看胆量！！
