设计一个pygame的斗地主游戏

好的，我可以给你提供一个简单的斗地主游戏的框架，你可以在此基础上进行修改和完善。

首先，我们需要导入pygame库和random库:

import pygame
import random

然后，我们需要定义一些常量，如窗口大小、牌的图片和位置等:

pygame.init()

# 窗口大小
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600

# 牌的图片和位置
CARD_WIDTH = 71
CARD_HEIGHT = 96
CARD_GAP = 20

# 加载牌的图片
cards_img = pygame.image.load('cards.png')

# 定义牌的位置
card_pos = {
    '01': (0, 0), '02': (CARD_WIDTH + CARD_GAP, 0), '03': (2 * (CARD_WIDTH + CARD_GAP), 0), '04': (3 * (CARD_WIDTH + CARD_GAP), 0),
    '05': (4 * (CARD_WIDTH + CARD_GAP), 0), '06': (5 * (CARD_WIDTH + CARD_GAP), 0), '07': (6 * (CARD_WIDTH + CARD_GAP), 0),
    '08': (7 * (CARD_WIDTH + CARD_GAP), 0), '09': (8 * (CARD_WIDTH + CARD_GAP), 0), '10': (9 * (CARD_WIDTH + CARD_GAP), 0),
    '11': (10 * (CARD_WIDTH + CARD_GAP), 0), '12': (11 * (CARD_WIDTH + CARD_GAP), 0), '13': (12 * (CARD_WIDTH + CARD_GAP), 0),
    '14': (0, CARD_HEIGHT + CARD_GAP), '15': (CARD_WIDTH + CARD_GAP, CARD_HEIGHT + CARD_GAP), '16': (2 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP),
    '17': (3 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP), '18': (4 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP), '19': (5 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP),
    '20': (6 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP), '21': (7 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP), '22': (8 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP),
    '23': (9 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP), '24': (10 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP), '25': (11 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP),
    '26': (12 * (CARD_WIDTH + CARD_GAP), CARD_HEIGHT + CARD_GAP), '27': (0, 2 * (CARD_HEIGHT + CARD_GAP)), '28': (CARD_WIDTH + CARD_GAP, 2 * (CARD_HEIGHT + CARD_GAP)),
    '29': (2 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)), '30': (3 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)), '31': (4 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)),
    '32': (5 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)), '33': (6 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)), '34': (7 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)),
    '35': (8 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)), '36': (9 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)), '37': (10 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)),
    '38': (11 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)), '39': (12 * (CARD_WIDTH + CARD_GAP), 2 * (CARD_HEIGHT + CARD_GAP)), '40': (WINDOW_WIDTH // 2 - CARD_WIDTH // 2, WINDOW_HEIGHT // 2 - CARD_HEIGHT // 2),
    '41': (WINDOW_WIDTH // 2 - CARD_WIDTH // 2 - CARD_GAP - CARD_WIDTH, WINDOW_HEIGHT // 2 - CARD_HEIGHT // 2), '42': (WINDOW_WIDTH // 2 - CARD_WIDTH // 2 + CARD_GAP + CARD_WIDTH, WINDOW_HEIGHT // 2 - CARD_HEIGHT // 2)
}

接着，我们需要定义一些类，如玩家类、牌类等:

# 玩家类
class Player:
    def __init__(self, name, cards):
        self.name = name   # 玩家名
        self.cards = cards  # 手牌

    def add_cards(self, cards):
        self.cards += cards  # 添加牌到手牌

    def play_cards(self, cards):
        for card in cards:
            self.cards.remove(card)  # 从手牌中移除已出的牌

    def sort_cards(self):
        self.cards.sort()  # 对手牌排序

# 牌类
class Card:
    def __init__(self, code):
        self.code = code  # 牌的编号
        self.img = cards_img.subsurface(pygame.Rect(card_pos[code], (CARD_WIDTH, CARD_HEIGHT)))  # 牌的图片

    def __lt__(self, other):
        return int(self.code) < int(other.code)  # 比较大小

# 牌堆类
class CardHeap:
    def __init__(self):
        self.cards = []  # 牌堆中的牌

    def shuffle(self):
        random.shuffle(self.cards)  # 洗牌

    def deal(self, num):
        dealt_cards = self.cards[:num]  # 发牌
        self.cards = self.cards[num:]
        return dealt_cards

    def add_cards(self, cards):
        self.cards += cards  # 添加牌到牌堆

然后，我们需要定义一些函数，如绘制牌、绘制玩家和牌堆、游戏主循环等:

# 绘制牌
def draw_cards(cards, pos):
    for i, card in enumerate(cards):
        screen.blit(card.img, (pos[0] + i * CARD_GAP, pos[1]))

# 绘制玩家和牌堆
def draw_players_and_heap(players, heap):
    for i, player in enumerate(players):
        name_font = pygame.font.Font(None, 30)
        name_text = name_font.render(player.name, True, (255, 255, 255))
        screen.blit(name_text, (20, WINDOW_HEIGHT - 70 - i * 120))

        draw_cards(player.cards, (20, WINDOW_HEIGHT - 40 - i * 120))

    draw_cards(heap.cards, card_pos['40'])

# 游戏主循环
def main_loop():
    # 初始化玩家和牌堆
    players = [Player('Player1', []), Player('Player2', []), Player('Player3', [])]
    heap = CardHeap()

    for code in card_pos.keys():
        heap.cards.append(Card(code))

    heap.shuffle()

    for i in range(17):
        for player in players:
            player.add_cards(heap.deal(1))

    heap.cards.sort(reverse=True)

    # 游戏主循环
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                exit()

        screen.fill((0, 128, 0))

        draw_players_and_heap(players, heap)

        pygame.display.update()

pygame.display.set_caption('斗地主')
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))

main_loop()

到这里，我们就完成了斗地主游戏的框架，你可以在此基础上进行修改和完善，比如添加出牌、抢地主、结算等功能。
