前言
最近在網(wǎng)上看到一個(gè)有意思的開源項(xiàng)目，基于快手團(tuán)隊(duì)開發(fā)的開源AI斗地主——DouZero做的一個(gè)“成熟”的AI，項(xiàng)目開源地址【https://github.com/tianqiraf/DouZero_For_HappyDouDiZhu – tianqiraf】。
今天我們就一起來學(xué)習(xí)下是如何制作一個(gè)基于DouZero的出牌器，看看AI是如何來幫助斗地主的！
一、核心功能設(shè)計(jì)
首先這款出牌器是基于DouZero開發(fā)的，核心是需要利用訓(xùn)練好的AI模型來幫住我們，給出最優(yōu)出牌方案。
其次關(guān)于出牌器，先要需要確認(rèn)一個(gè)AI出牌角色，代表我們玩家自己。我們只要給這個(gè)AI輸入玩家手牌和三張底牌。確認(rèn)好地主和農(nóng)民的各個(gè)角色，告訴它三個(gè)人對(duì)應(yīng)的關(guān)系，這樣就可以確定隊(duì)友和對(duì)手。
我們還要將每一輪其他兩人的出牌輸入，這樣出牌器就可以根據(jù)出牌數(shù)據(jù)，及時(shí)提供給我們最優(yōu)出牌決策，帶領(lǐng)我們?nèi)〉脛倮?/p>
那么如何獲取三者之間的關(guān)系呢？誰是地主？誰是農(nóng)民？是自己一人作戰(zhàn)還是農(nóng)民合作？自己玩家的手牌是什么？三張底牌是什么？這些也都需要在開局后確認(rèn)好。
大致可以整理出要實(shí)現(xiàn)的核心功能如下：
UI設(shè)計(jì)排版布局
- 顯示三張底牌
- 顯示AI角色出牌數(shù)據(jù)區(qū)域，上家出牌數(shù)據(jù)區(qū)域，下家出牌數(shù)據(jù)區(qū)域，本局勝率區(qū)域
- AI玩家手牌區(qū)域
- AI出牌器開始停止
手牌和出牌數(shù)據(jù)識(shí)別
- 游戲剛開始根據(jù)屏幕位置，截圖識(shí)別AI玩家手牌及三張底牌
- 確認(rèn)三者之間的關(guān)系，識(shí)別地主和農(nóng)民角色，確認(rèn)隊(duì)友及對(duì)手關(guān)系
- 識(shí)別每輪三位玩家依次出了什么牌，刷新顯示對(duì)應(yīng)區(qū)域
AI出牌方案輸出
- 加載訓(xùn)練好的AI模型，初始化游戲環(huán)境
- 每輪出牌判斷，根據(jù)上家出牌數(shù)據(jù)給出最優(yōu)出牌決策
- 自動(dòng)刷新玩家剩余手牌和本局勝率預(yù)測(cè)
二、實(shí)現(xiàn)步驟
1. UI設(shè)計(jì)排版布局
根據(jù)上述功能，首先考慮進(jìn)行簡(jiǎn)單的UI布局設(shè)計(jì)，使用的是pyqt5。核心設(shè)計(jì)代碼如下：

font.setWeight(75)
self.Stop.setFont(font)
self.Stop.setStyleSheet("")
self.Stop.setObjectName("Stop")
self.retranslateUi(Form)
self.InitCard.clicked.connect(Form.init_cards)
self.Stop.clicked.connect(Form.stop)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "AI歡樂斗地主--Dragon少年"))
self.WinRate.setText(_translate("Form", "勝率：--%"))
self.InitCard.setText(_translate("Form", "開始"))
self.UserHandCards.setText(_translate("Form", "手牌"))
self.LPlayedCard.setText(_translate("Form", "上家出牌區(qū)域"))
self.RPlayedCard.setText(_translate("Form", "下家出牌區(qū)域"))
self.PredictedCard.setText(_translate("Form", "AI出牌區(qū)域"))
self.ThreeLandlordCards.setText(_translate("Form", "三張底牌"))
self.Stop.setText(_translate("Form", "停止"))
2. 手牌和出牌數(shù)據(jù)識(shí)別
接下來需要所有撲克牌的模板圖片與游戲屏幕特定區(qū)域的截圖進(jìn)行對(duì)比，這樣才能獲取AI玩家手牌、底牌、每一輪出牌、三者關(guān)系（地主、地主上家、地主下家）。
識(shí)別AI玩家手牌及三張底牌：
我們可以截取游戲屏幕，根據(jù)固定位置來識(shí)別當(dāng)前AI玩家的手牌和三張底牌。核心代碼如下：
# 牌檢測(cè)結(jié)果濾波
def cards_filter(self, location, distance):
if len(location) == 0:
return 0
locList = [location[0][0]]
count = 1
for e in location:
flag = 1 # “是新的”標(biāo)志
for have in locList:
if abs(e[0] - have) = distance:
flag = 0
break
if flag:
count += 1
locList.append(e[0])
return count
# 獲取玩家AI手牌
def find_my_cards(self, pos):
user_hand_cards_real = ""
img = pyautogui.screenshot(region=pos)
for card in AllCards:
result = pyautogui.locateAll(needleImage='pics/m' + card + '.png', haystackImage=img, confidence=self.MyConfidence)
user_hand_cards_real += card[1] * self.cards_filter(list(result), self.MyFilter)
return user_hand_cards_real
# 獲取地主三張底牌
def find_three_landlord_cards(self, pos):
three_landlord_cards_real = ""
img = pyautogui.screenshot(region=pos)
img = img.resize((349, 168))
for card in AllCards:
result = pyautogui.locateAll(needleImage='pics/o' + card + '.png', haystackImage=img,
confidence=self.ThreeLandlordCardsConfidence)
three_landlord_cards_real += card[1] * self.cards_filter(list(result), self.OtherFilter)
return three_landlord_cards_real
效果如下所示：
地主、地主上家、地主下家：
同理我們可以根據(jù)游戲屏幕截圖，識(shí)別地主的圖標(biāo)，確認(rèn)地主角色。核心代碼如下：
# 查找地主角色
def find_landlord(self, landlord_flag_pos):
for pos in landlord_flag_pos:
result = pyautogui.locateOnScreen('pics/landlord_words.png', region=pos, confidence=self.LandlordFlagConfidence)
if result is not None:
return landlord_flag_pos.index(pos)
return None
這樣我們就可以得到玩家AI手牌，其他玩家手牌（預(yù)測(cè)），地主三張底牌，三者角色關(guān)系，出牌順序。核心代碼如下：
# 坐標(biāo)
self.MyHandCardsPos = (414, 804, 1041, 59) # AI玩家截圖區(qū)域
self.LPlayedCardsPos = (530, 470, 380, 160) # 左側(cè)玩家截圖區(qū)域
self.RPlayedCardsPos = (1010, 470, 380, 160) # 右側(cè)玩家截圖區(qū)域
self.LandlordFlagPos = [(1320, 300, 110, 140), (320, 720, 110, 140), (500, 300, 110, 140)] # 地主標(biāo)志截圖區(qū)域(右-我-左)
self.ThreeLandlordCardsPos = (817, 36, 287, 136) # 地主底牌截圖區(qū)域，resize成349x168
def init_cards(self):
# 玩家手牌
self.user_hand_cards_real = ""
self.user_hand_cards_env = []
# 其他玩家出牌
self.other_played_cards_real = ""
self.other_played_cards_env = []
# 其他玩家手牌（整副牌減去玩家手牌，后續(xù)再減掉歷史出牌）
self.other_hand_cards = []
# 三張底牌
self.three_landlord_cards_real = ""
self.three_landlord_cards_env = []
# 玩家角色代碼：0-地主上家, 1-地主, 2-地主下家
self.user_position_code = None
self.user_position = ""
# 開局時(shí)三個(gè)玩家的手牌
self.card_play_data_list = {}
# 出牌順序：0-玩家出牌, 1-玩家下家出牌, 2-玩家上家出牌
self.play_order = 0
self.env = None
# 識(shí)別玩家手牌
self.user_hand_cards_real = self.find_my_cards(self.MyHandCardsPos)
self.UserHandCards.setText(self.user_hand_cards_real)
self.user_hand_cards_env = [RealCard2EnvCard[c] for c in list(self.user_hand_cards_real)]
# 識(shí)別三張底牌
self.three_landlord_cards_real = self.find_three_landlord_cards(self.ThreeLandlordCardsPos)
self.ThreeLandlordCards.setText("底牌：" + self.three_landlord_cards_real)
self.three_landlord_cards_env = [RealCard2EnvCard[c] for c in list(self.three_landlord_cards_real)]
# 識(shí)別玩家的角色
self.user_position_code = self.find_landlord(self.LandlordFlagPos)
if self.user_position_code is None:
items = ("地主上家", "地主", "地主下家")
item, okPressed = QInputDialog.getItem(self, "選擇角色", "未識(shí)別到地主，請(qǐng)手動(dòng)選擇角色:", items, 0, False)
if okPressed and item:
self.user_position_code = items.index(item)
else:
return
self.user_position = ['landlord_up', 'landlord', 'landlord_down'][self.user_position_code]
for player in self.Players:
player.setStyleSheet('background-color: rgba(255, 0, 0, 0);')
self.Players[self.user_position_code].setStyleSheet('background-color: rgba(255, 0, 0, 0.1);')
# 整副牌減去玩家手上的牌，就是其他人的手牌,再分配給另外兩個(gè)角色（如何分配對(duì)AI判斷沒有影響）
for i in set(AllEnvCard):
self.other_hand_cards.extend([i] * (AllEnvCard.count(i) - self.user_hand_cards_env.count(i)))
self.card_play_data_list.update({
'three_landlord_cards': self.three_landlord_cards_env,
['landlord_up', 'landlord', 'landlord_down'][(self.user_position_code + 0) % 3]:
self.user_hand_cards_env,
['landlord_up', 'landlord', 'landlord_down'][(self.user_position_code + 1) % 3]:
self.other_hand_cards[0:17] if (self.user_position_code + 1) % 3 != 1 else self.other_hand_cards[17:],
['landlord_up', 'landlord', 'landlord_down'][(self.user_position_code + 2) % 3]:
self.other_hand_cards[0:17] if (self.user_position_code + 1) % 3 == 1 else self.other_hand_cards[17:]
})
print(self.card_play_data_list)
# 生成手牌結(jié)束，校驗(yàn)手牌數(shù)量
if len(self.card_play_data_list["three_landlord_cards"]) != 3:
QMessageBox.critical(self, "底牌識(shí)別出錯(cuò)", "底牌必須是3張！", QMessageBox.Yes, QMessageBox.Yes)
self.init_display()
return
if len(self.card_play_data_list["landlord_up"]) != 17 or \
len(self.card_play_data_list["landlord_down"]) != 17 or \
len(self.card_play_data_list["landlord"]) != 20:
QMessageBox.critical(self, "手牌識(shí)別出錯(cuò)", "初始手牌數(shù)目有誤", QMessageBox.Yes, QMessageBox.Yes)
self.init_display()
return
# 得到出牌順序
self.play_order = 0 if self.user_position == "landlord" else 1 if self.user_position == "landlord_up" else 2
效果如下：
3. AI出牌方案輸出
下面我們就需要用到DouZero開源的AI斗地主了。DouZero項(xiàng)目地址：https://github.com/kwai/DouZero。我們需要將該開源項(xiàng)目下載并導(dǎo)入項(xiàng)目中。
創(chuàng)建一個(gè)AI玩家角色，初始化游戲環(huán)境，加載模型，進(jìn)行每輪的出牌判斷，控制一局游戲流程的進(jìn)行和結(jié)束。核心代碼如下：
# 創(chuàng)建一個(gè)代表玩家的AI
ai_players = [0, 0]
ai_players[0] = self.user_position
ai_players[1] = DeepAgent(self.user_position, self.card_play_model_path_dict[self.user_position])
# 初始化游戲環(huán)境
self.env = GameEnv(ai_players)
# 游戲開始
self.start()
def start(self):
self.env.card_play_init(self.card_play_data_list)
print("開始出牌\n")
while not self.env.game_over:
# 玩家出牌時(shí)就通過智能體獲取action，否則通過識(shí)別獲取其他玩家出牌
if self.play_order == 0:
self.PredictedCard.setText("...")
action_message = self.env.step(self.user_position)
# 更新界面
self.UserHandCards.setText("手牌：" + str(''.join(

self.PredictedCard.setText(action_message["action"] if action_message["action"] else "不出")
self.WinRate.setText("勝率：" + action_message["win_rate"])
print("\n手牌：", str(''.join(

print("出牌：", action_message["action"] if action_message["action"] else "不出", "， 勝率：",
action_message["win_rate"])
while self.have_white(self.RPlayedCardsPos) == 1 or \
pyautogui.locateOnScreen('pics/pass.png',
region=self.RPlayedCardsPos,

self.play_order = 2

self.init_display()
到這里，整個(gè)AI斗地主出牌流程基本已經(jīng)完成了。
三、出牌器用法
按照上述過程，這款A(yù)I出牌器已經(jīng)制作完成了。后面應(yīng)該如何使用呢？如果不想研究源碼，只想使用這款A(yù)I斗地主出牌器，驗(yàn)證下效果，該怎么配置環(huán)境運(yùn)行這個(gè)AI出牌器呢？下面就開始介紹。
1. 環(huán)境配置
首先我們需要安裝這些第三方庫，配置相關(guān)環(huán)境，如下所示：
torch==1.9.0
GitPython==3.0.5
gitdb2==2.0.6
PyAutoGUI==0.9.50
PyQt5==5.13.0
PyQt5-sip==12.8.1
Pillow>=5.2.0
opencv-python
rlcard
2. 坐標(biāo)調(diào)整確認(rèn)
我們可以打開游戲界面，將游戲窗口模式下最大化運(yùn)行，把AI出牌器程序窗口需要移至右下角，不能遮擋手牌、地主標(biāo)志、底牌、歷史出牌這些關(guān)鍵位置。
其次我們要確認(rèn)屏幕截圖獲取的各個(gè)區(qū)域是否正確。如果有問題需要進(jìn)行區(qū)域位置坐標(biāo)調(diào)整。
# 坐標(biāo)
self.MyHandCardsPos = (414, 804, 1041, 59) # 我的截圖區(qū)域
self.LPlayedCardsPos = (530, 470, 380, 160) # 左邊截圖區(qū)域
self.RPlayedCardsPos = (1010, 470, 380, 160) # 右邊截圖區(qū)域
self.LandlordFlagPos = [(1320, 300, 110, 140), (320, 720, 110, 140), (500, 300, 110, 140)] # 地主標(biāo)志截圖區(qū)域(右-我-左)
self.ThreeLandlordCardsPos = (817, 36, 287, 136) # 地主底牌截圖區(qū)域，resize成349x168
3. 運(yùn)行測(cè)試
當(dāng)所有環(huán)境配置完成，各區(qū)域坐標(biāo)位置確認(rèn)無誤之后，下面我們就可以直接運(yùn)行程序，測(cè)試效果啦~
首先我們運(yùn)行AI出牌器程序，打開游戲界面，進(jìn)入游戲。當(dāng)玩家就位，手牌分發(fā)完畢，地主身份確認(rèn)之后，我們就可以點(diǎn)擊畫面中開始按鈕，讓AI來幫助我們斗地主了。
基于這個(gè)DouZero項(xiàng)目做一個(gè)“成熟”的AI，項(xiàng)目開源地址【https://github.com/tianqiraf/DouZero_For_HappyDouDiZhu – tianqiraf】。
