Question

我需要制作一个类来绘制字符屏幕中心，并使图像的背景颜色与屏幕的背景颜色匹配，反之亦然。我已经将Pygame屏幕的背景色的值设置为蓝色，但是当我在DrawCharacter类中执行同样的操作时，它只是使用图像的背景色（白色）打开了屏幕。我可能只是将bg_color属性放在班级的错误位置。

game_character.py

import sys
import pygame

class DrawCharacter():
    bg_color = ((0, 0, 255))
    def __init__(self, screen):
        """Initialize the superman and set starting position"""
        self.screen = screen

        # Load image and get rect
        self.image = pygame.image.load("Images/supermen.bmp")
        self.rect = self.image.get_rect()
        self.screen_rect = screen.get_rect()

        # Start each new supermen at the center of the screen
        self.rect.centerx = self.screen_rect.centerx
        self.rect.centery = self.screen_rect.centery

    def blitme(self):
        """Draw the superman at its current location"""
        self.screen.blit(self.image, self.rect)

blue_sky.py

import  sys
import pygame
from game_character import DrawCharacter

def run_game():
    # Initialize game and make screen object
    pygame.init()
    screen = pygame.display.set_mode((1200, 800))
    pygame.display.set_caption("Blue Sky")
    bg_color = (0, 0, 255)

    # Make superman
    superman = DrawCharacter(screen)

    # Start the main loop for the game
    while True:

        # Check for keyboard and mouse events
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()

        # Redraw screen during each loop pass
        screen.fill(bg_color)
        superman.blitme()
        # make the most recently drawn screen visible
        pygame.display.flip()
    run_game()

我希望图像的背景颜色与Pygame屏幕的背景颜色相同，但事实并非如此。第一个代码块用于我的课程文件，第二个代码块用于pygame文件

如果图像具有透明背景，请尝试在game_Character.py中执行以下操作：

# Load image and get rect
    self.image = pygame.image.load("Images/supermen.bmp").convert_alpha()
    self.rect = self.image.get_rect()
    self.screen_rect = screen.get_rect()

如果背景为白色，则可能需要像这样设置色键：

    # Load image and get rect
        self.image = pygame.image.load("Images/supermen.bmp").convert()
        self.image.set_colorkey((255, 255, 255))
        self.rect = self.image.get_rect()
        self.screen_rect = screen.get_rect()

如何将图像的背景颜色与Pygame的背景颜色进行匹配？
