如何在Pygame的一类纸牌中添加一堆png？

如何解决如何在Pygame的一类纸牌中添加一堆png？

因此，我通过所学课程学习了如何制作具有各种功能的一副纸牌。现在，我想使用我制作的类和我的png文件创建一个可以在pygame窗口中使用的平台。当我运行各种功能时e.x. deal_card()，它会以“ 4 of Clubs”的格式返回一张卡，因此我知道它可以使用。如何获得那些能真正代表我所拥有的卡片图像的png？

import pygame
import os
from random import shuffle

# Initialize the pygame
pygame.init()


# Setting up the screen and background
screen = pygame.display.set_mode((800,600))


# Title and Icon of window
pygame.display.set_caption("Blackjack")

icon = pygame.image.load('card-game.png')
pygame.display.set_icon(icon)


class Card:
    def __init__(self,value,suit):
        self.value = value
        self.suit = suit

    def __repr__(self):
        # return "{} of {}".format(self.value,self.suit)
        return f"{self.value} of {self.suit}"



class Deck:
    def __init__(self):
        suits = ["Clubs","Diamonds","Hearts","Spades"]
        values = ['A','2','3','4','5','6','7','8','9','10','J','Q','K']
        self.cards = [Card(value,suit) for suit in suits for value in values]

    def __repr__(self):
        return f"Deck of {self.count()} cards"

    def count(self):
        return len(self.cards)

    def _deal(self,num):
        count = self.count()
        actual = min([count,num])
        if count == 0:
            raise ValueError("All cards have been dealt")
        cards = self.cards[-actual:]
        self.cards = self.cards[:-actual]
        return cards

    def deal_card(self):
        return self._deal(1)[0]

    def deal_hand(self,hand_size):
        return self._deal(hand_size)

    def shuffle(self):
        if self.count() < 52:
            raise ValueError("Only full decks can be shuffled")
        shuffle(self.cards)
        return self



# Game Loop that ensures window is always running.
# We make sure we do our stuff in this loop
running = True
while running:

    # RGB
    screen.fill((50,0))

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    
    # RGB
    screen.fill((50,0))

解决方法

PNG 的名称为：2 of Clubs、K of Hearts 等。

卡的文件名对应卡的“官方”字符串表示（__repr__）。通过文件扩展名 (.png) 扩展名称并使用 pygame.image.load 加载卡片图像：

class Card:
    def __init__(self,value,suit):
        self.value = value
        self.suit = suit

        self.image = pygame.image.load(str(self) + '.png')

    def __repr__(self):
        # return "{} of {}".format(self.value,self.suit)
        return f"{self.value} of {self.suit}"
