Pygame 无法加载背景图片？

Question

我得到的只是黑屏。不确定我是否在目录中找不到图像，或者如果我没有正确调用某些图像...但它没有给我错误，所以我不确定该怎么做。

import pygame
# Intialize the pygame
pygame.init()

# Create the screen 
screen = pygame.display.set_mode((300, 180))

#Title and Icon
pygame.display.set_caption("Fighting Game")

# Add's logo to the window 
# icon = pygame.image.load('')
# pygame.display.set_icon(icon)

#  Game Loop
running = True
while running:
    # screen.fill((0, 0, 0))
    # screen.blit(BackGround.image, BackGround.rect)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False


class Background(pygame.sprite.Sprite):
    def __init__(self, image_file, location):
        pygame.sprite.Sprite.__init__(self)  #call Sprite initializer
        self.image = pygame.image.load("images/image.png")
        self.rect = self.image.get_rect(300,180)
        self.rect.left, self.rect.top = location

BackGround = Background('image.png', [0,0])

screen.fill((0, 0, 0))
screen.blit(BackGround.image, BackGround.rect)

Answer 1

您必须 blit 主应用程序循环中的图像，并且必须通过 pygame.display.flip 更新显示。

此外，没有必要将任何参数传递给self.image.get_rect()。无论如何， get_rect() 的参数必须是关键字参数。您可以做的是通过关键字参数 topleft.

设置位置

class Background(pygame.sprite.Sprite):
    def __init__(self, image_file, location):
        pygame.sprite.Sprite.__init__(self)  #call Sprite initializer
        self.image = pygame.image.load("images/image.png")
        self.rect = self.image.get_rect(topleft = location)

BackGround = Background('image.png', [0,0])

#  Game Loop
running = True
while running:
    # screen.fill((0, 0, 0))
    # screen.blit(BackGround.image, BackGround.rect)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    #screen.fill((0, 0, 0)) # unnecessary because of the background image
    screen.blit(BackGround.image, BackGround.rect)
    pygame.display.flip()

注意，主应用程序循环必须：

处理事件
清除显示或 blit 背景图像
绘制场景
更新显示
