Question

我正在关注pygame教程，所以我的子画面无法显示在窗口中。当我运行程序时，我看到矩形在屏幕上移动，但是它只显示全黑。我尝试根据窗口更改矩形上的背景颜色，但仍然没有任何反应。我确实注意到矩形会根据我尝试加载的不同图像而改变形状。这是代码。谢谢

import pygame
import random
import os

WIDTH = 800
HEIGHT = 600
FPS = 30

# define colors
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)

#SET ASSETS FOLDERS
game_folder = os.path.dirname(__file__)
img_folder = os.path.join(game_folder, "img")

class Player(pygame.sprite.Sprite):
    # sprite for the Player
    def __init__(self):
        # this line is required to properly create the sprite
        pygame.sprite.Sprite.__init__(self)
        # create a plain rectangle for the sprite image
        self.image = pygame.image.load(os.path.join(img_folder, "p1_jump.png")).convert()


        # find the rectangle that encloses the image
        self.rect = self.image.get_rect()
        # center the sprite on the screen
        self.rect.center = (WIDTH / 2, HEIGHT / 2)

    def update(self):
        # any code here will happen every time the game loop updates
        self.rect.x += 5
        if self.rect.left > WIDTH:
            self.rect.right = 0

# initialize pygame and create window
pygame.init()
pygame.mixer.init()
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Sprite Example")
clock = pygame.time.Clock()

all_sprites = pygame.sprite.Group()
player = Player()
all_sprites.add(player)
# Game loop
running = True
while running:
    # keep loop running at the right speed
    clock.tick(FPS)
    # Process input (events)
    for event in pygame.event.get():
        # check for closing window
        if event.type == pygame.QUIT:
            running = False

    # Update
    all_sprites.update()

    # Draw / render
    screen.fill(GREEN)
    all_sprites.draw(screen)
    # *after* drawing everything, flip the display
enter code herepygame.display.flip()

pygame.quit()

我只是在您的问题的代码末尾更改了一行，它开始起作用：

    .
    .
    .
# Game loop
running = True
while running:
    # keep loop running at the right speed
    clock.tick(FPS)
    # Process input (events)
    for event in pygame.event.get():
        # check for closing window
        if event.type == pygame.QUIT:
            running = False

    # Update
    all_sprites.update()

    # Draw / render
    screen.fill(GREEN)
    all_sprites.draw(screen)
    # *after* drawing everything, flip the display
    pygame.display.flip()  # <----- FIX THIS LINE

pygame.quit()
