学习 python 和 OOP

Question

我试图通过调用 class 来对我拥有的那两张图像进行 blit，但我认为这不是正确的方法。

import pygame


class Ball:

    def __init__(self):
        self.screen = pygame.display.set_mode((1024, 960))
        self.bg_color = self.screen.fill("White")
        self.bg = pygame.image.load("Bg/PowLow.png")
        self.ball = pygame.image.load("karaktär/Char.png")
        self.caption = pygame.display.set_caption("PowLow's Game")
        self.gameloop()

    def gameloop(self):
        pygame.init()
        clock = pygame.time.Clock()
        pygame.display.update()
        running = True
        while running:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    running = False
            self.draw()

    def draw(self):
        draw_ball = self.screen.blit(self.ball, (0, 0))
        draw_bg = self.screen.blit(self.bg, (0, 300))


Ball()
